The technical FIELD TO WHICH the INVENTION RELATES.

The invention relates to the reading of the photosensitive pixels in a photosensitive crystals, specifically, to read subdescription data photosensitive pixels in a photosensitive crystals with a large matrix. In particular, the invention relates to multi-spectral photosensitive device, and methods for their discretization.

The LEVEL of TECHNOLOGY

This application is a continuation application, called "Multi-Spectrum Photosensitive Devices and Methods for manufacturing the Same" (PCT/CN2007/071262) and "Multi-Spectrum Photosensitive Devices and Methods for manufacturing the Same" (application (China) room 200810217270.2), submitted by the author(s) of the present invention, and is aimed at providing a more specific and preferred implementations at the level of semiconductor circuits and crystals.

Preceding photosensitive devices associated with the reading of the color of visible light or infrared light when a rare simultaneous reading of both of them. Although some other inventions or applications, for example, semiconductor technology based on cadmium, and indium ("Silicon infrared focal plane arrays", M. Kimata, in Handbook of Infrared Detection Technologies, edited by M Henini and M. Razeghi, p. 352-392, Elsevier Science Ltd., 2002), can also be used to implement simultaneous fotostation as for the invisible light is infrared light, but the color is not achieved. Previous methods for simultaneous receipt of photosensitivity colored light and infrared light are to physically impose on each other, colored photosensitive device and an infrared photosensitive device (for example, "Backside-hybrid Photodetector for trans-chip detection of NIR light" authors T. Tokuda, and others, in IEEE Workshop on Charge-coupled Devices and Advanced Image Sensors, Elmau, Germany, may 2003, and "A CMOS image sensor with eye-safe detection function backside carrier injection", T. Tokuda, etc., J. Inst Image Information and Television Eng.(3): 366-372, March 2006).

A new method for the manufacture of multi-spectral photosensitive device, to simultaneously obtain color and infrared images, it is proposed in the earlier application, called "Multi-Spectrum Photosensitive Devices and Methods for manufacturing the Same" (PCT/CN2007/071262) and "Multi-Spectrum Photosensitive Devices and Methods for manufacturing the Same" (application (China) room 200810217270.2)filed by the author of the present invention. In a photosensitive devices of a new type of enhanced dynamic photosensitive ranges photosensitive devices so that they meet the stringent performance requirements in the areas of technology, vehicles, security and surveillance, etc. in Addition, they can be used in the colored photosensitive devices of small size, such as camera cell the phone, and the image quality can be improved dramatically. In addition, they can be manufactured by applying the manufacturing technologies existing CMOS, CCD or other photosensitive semiconductor devices and many effective ways of manufacturing and structural design can be used in these technologies. Some methods of fabrication using CMOS/CCD semiconductor technology available in this application.

However, a new problem emerging as a result of the new two-layer or multi-layer photosensitive devices is that the amount of data twice or more greater than the amount of data the traditional single-layer photosensitive devices. Although only half-PEL may be necessary to obtain permission of the double-layer photosensitive device, identical to the resolution of the single-layer photosensitive devices, data processing for a large matrix of photosensitive devices at high speeds remains a problem that must be resolved.

Recently some excellent methods for domain downsampling images for a large matrix with high performance, such as a shared readout circuit, technology sample grouped by the line and grouping columns are offered in some applications, for example in patents (US) non 6801258B1, 6693670B1, 7091466B2, 7319218B2, etc. of these proposals deserve attention patents (US) non 6693670B1, 7091466B2 and 7319218B2 that provide some effective and simple approaches to implement the grouping of N columns or N rows or grouping of M columns and N rows.

However, these technologies still are not optimal. For example, the signal-to-noise ratio (SNR) of the image is improved only thenNtime by combining the N points into one through the use of operations subdirectly grouped by rows and group by columns (see the patents (US) non 7091466B2 and 7319218B2). This is because the signals are simply averaged in the operations of grouping by rows and/or columns, thereby reducing the variance of the random noise only inNonce, while themselves useful signals are not amplified, and are simply replaced by an average value of several points. In addition, there are usually slowly varying and low-frequency noise in the image signal, which generally is not reduced.

In addition, existing technologies subdirectly consider only the requirements of subdirectly fot the sensitive crystal, placed in the Bayer pattern or CYMG-template separately, and do not provide for ease in handling postdispersal. For example, a color image of the Bayer pattern remains the image of the Bayer pattern through the use of sampling operations with grouping by rows and group by columns (see the patents (US) non 7091466B2 and 7319218B2)used by U. S Micron Technologies Inc., and in this case, in order to obtain YUV images, which are favoured in the stages preview and storage still requires complex processes. Although some other scheme subdirectory can improve SNR, they require complex integrated circuits and modules of the comparison, thereby increasing the number of auxiliary circuits and frequency.

Another significant limitation of existing technologies subdirectly is that the grouping operation on the rows and group by columns apply only to the pixels that reads one color, and the pixels are not directly adjacent in space (i.e., other pixels can be placed between them). For templates Bayer or CYMG color patterns, pixels of the same color are not directly adjacent in space, and feature a uniform spatial distribution of the source image is disturbed due to surgery is grouping by rows and group by columns. Therefore, the effects of aliasing are easily formed on the edges of the lines, if definitive treatment is not specially adapted to the occasion.

In particular, for two-layer or multi-layer photosensitive devices, which are discussed in this application, the prior art seems to be quite awkward and mediocre as a two-layer or multi-layer photosensitive devices provide many excellent, but completely new layouts color pattern, for which the reading and the downsampled signals must use the characteristics of two-layer or multi-layer photosensitive devices in order to perform improvements.

TECHNICAL ADVANTAGES

This application has the following advantages.

In this application the process of subdirectly is divided at least into two processes, i.e., the above-mentioned first process of combining and sampling and the second process of combining and sampling. The first and second processes of combining and sampling is usually carried out between (combined) sampling lines and (combining) the discretization of the columns of pixels and mainly implemented for analog signals, in which order, and the operations are in General variable, except for the imposition of charges, which is usually performed only in the first process of combining and sampling. In addition, in addition, may include a third process of combining and sampling, which is carried out mainly for digital signals after analog-to-digital conversion.

In the first process of combining and sampling combined two directly neighboring pixel in the pixel matrix. On the one hand, is a combination of directly neighboring pixels. In this document the pixel obtained after combining, referred to as the first combined pixel. It should be understood that the concept of the first combined pixel for the convenience of the izania used to specify the pixel obtained after the first process of combining. It has no intention to indicate that "the first combined pixel" physically exists in the pixel matrix. Data obtained by combining and subdirectory for two neighboring pixels, referred to as the ' sample data of the first combined pixel. The term "directly adjacent", as used herein, means that two pixels are adjacent when viewed from a horizontal, vertical or diagonal direction without placing other pixels between them. Cases directly neighboring include two pixels located in the same row but in different columns or rows, but in the same column or in different rows and different columns. Generally speaking, this combined signal is obtained through the average of at least two signals, so that noise is reduced inNtime. Therefore, the SNR will be increased, at least inNafter combining, the combining can be performed between pixels with the same or different colors. On the other hand, the pixels that have the ü combined, can have different colors, i.e., performs addition or averaging of colors. As is known from theory of the three primary colors, the color formed by combining two primary colors, is complementary with another primary color. You only want the color space conversion to migrate from the primary color space to an alternate color space. Thus, the recovery of colors can also be accomplished through a variety of complementary colors. In other words, the combination of pixels with different colors can be performed in order to improve SNR, and restore colors may also be implemented according to the present application. The General process of subdirectly is optimized so that it meets the high demand of the pixel matrix with a large amount of data. The basic requirement is to convert the color space is that the combination of colors after conversion allows the recovery of the desired RGB(or YUV or CYMK-) colors (via interpolation, and so on).

It should be noted that many pixels are usually contained in the pixel matrix, and only two pixels are combined in the first combination and sampling. Obviously, many of the first combined peak of the fir are obtained by combining. For various first combined pixel can be used identical or different ways of combining them. The first process of combination is referred to as the mode of combining one color when it is fully between pixels having the same color. The first process of combination is referred to as the mode of combining different colors when it is fully between pixels having different colors. The first process of combination is referred to as the hybrid mode combining, when he is done partly in pixels with one color, and partly in pixels having different colors. The first process of combination is referred to as the mode of election of eliminating redundant colors, when some pixels of the excess color in the pixel matrix are excluded (of course, such an exception is selective and should not be affected by, for example, to restore colors).

Obviously, the second combining operation is for many the first combined pixel. Similarly, it is possible to combine the first combined pixels with the same or different colors (of course, force all three primary colors can be folded, so that the recovery of colors cannot be executed).

The above modes of combination, i.e., kombinirov is their one color, combining different colors and a hybrid combination, are classified on the basis of color. In addition, from the point of view position selection combining and sampling modes of combination, and sampling the first and second combining include: automatic averaging of signals output directly to a single bus, skipping lines or skipping columns, discretization one item and combine two or three of these modes. Except for the imposition of charges, which is only performed in the first process of combining and sampling, the first and second process combination are identical and modifiable (except for their different order).

The mode of the so-called automatic averaging of signals output directly into the tire, is that the signals (one color or different colors)that should be combined, at the same time displays the bus data collection through the automatic balancing of the signals (voltage)to reach an average value of signals that need to be combined. Mode skip lines or skip columns is that some rows or columns are skipped so that (and combining) the discretization is performed by way of a reduced amount of data. The mode of sampling on one e the point is the source pixels or first combined pixel read sequentially without combining. Several of these three modes can be used simultaneously. For example, the skip mode lines or fewer columns may be used simultaneously with automatic averaging of signals output directly into the tire, or mode of sampling on a single element.

Mode subdirectly third process of combining and sampling includes color space conversion, the final scaling of digital images and consistent use of the two modes. The first and second processes combining mainly applied to analog signals, while the third process of combining mainly applies to digital signals, i.e., is applied after the analog-to-digital conversion. By processing three or four color pixels in different spatial locations as values for identical points and transformation values in another color space data in the horizontal and / or vertical direction must be reduced in order to achieve the benefits of subdirectly. In addition, the zoom mode digital images is the most intuitive mode subdisk is Itachi, which is usually used.

The imposition of charges is implemented by first combining and sampling of this application. Almost all of the downsampled in the prior art is performed by averaging the signals of the voltage or current at which the SNR can be increased up toNonce, when combined N points. The reason is that N pixels having the same color, are shared through the output line in an existing combination of bit rate and sample rate and thus the signal voltage or current of each pixel in this output line should be (automatically) average. Therefore, the improvement in SNR is only that the noise will be reduced inNafter combining, and thus the SNR will increase most inNtime. However, the SNR can be increased N times by using the mapping method of the charges of this application, for example by storing all related charges in the capacitor is read, in order to achieve the imposition of charges, so that the SNR should be improved, at least N times that in Ntimes higher than in the method for averaging signals. In other words, combining N signals by way of the imposition of charges allows to theoretically achieve the benefits of averaging N2or more signals (as described below), which is a method that greatly improves SNR.

Another significant advantage in the overlay adjacent (directly adjacent) pixels, is that crosstalk between pixels is reduced. This is because all the colors that initially interfere with each other, can now rightly belong to the combined signal. In other words, part of the signals, originally owned by noise, now become a useful part of the signal. Thus, the improvement in SNR caused by combining N signals can be theoretically close to the limit, i.e., to be NNtimes, thereby achieving the advantages of averaging N3signals.

The imposition of charges is a regime combining and sampling with a significant advantage, in which the pixels that need to be combined must be spatially contiguous. The reason that the second advantage can be achieved through the previous subdirectory, is that the earlier downsampled runs only between pixels with one color, and the pixels that should be combined, nesmin separated by other pixels. It is relatively easy to implement the imposition of charges for multi-layer photosensitive device, because of its color patterns are very busy. However, it is also easy to reach the imposition of charges in the single-layer photosensitive device is provided that performs a method of converting the color space of this application.

During sampling of the full image (i.e., sampling rate of one image in the highest resolution) in this application mode is set to progressive scan and interlaced readout, and thus the frame rate when reading the full picture for a large matrix of doubles during one image without increasing the clock frequency and use of the frame buffer. If you are adding an analog-to-digital Converter and the buffer columns, the frame rate when reading full image will be greatly enhanced. The method is important to avoid mechanical shutters.

It should be noted that the mode progressive scan and interlaced reading in this application differs from the way black is strachnogo scanning in the conventional television system. The traditional way of interlaced scanning is interlaced scanning and interlaced scanning. Therefore, the time (no matter the time of reading or time perception) between odd and even fields is the difference in one field, i.e., the difference in the half frame. However, the timing sequence readout pixel progressive scan and interlaced reading this application is identical to the time sequence reads in the way of progressive scan and line-by-line reading, except that the sequence of the read row is changed.

New photosensitive device and its method of subdirectly with great opportunities and a wider applicability according to the options of the implementation of this application are explained by means of exemplary embodiments. Preferred methods of implementation are only examples to demonstrate its implementations and advantages of the present application, but in no way to limit the scope of the application.

For specialists in the art the above and other objectives and advantages of this application shall become apparent from the subsequent descriptions and many illustrations of preferred options to implement the ia with reference to the accompanying drawings, as shown below.

Fig. 10 shows the main ideas of the existing technologies combining one color pixels, i.e. pixels are combined adjacent macropixels reading one color (averaging signals). Fig. 10(a) is the concept of combining lines, while Fig. 10(b) is a schematic diagram of a simultaneous combination of rows and columns.

Fig. 11 illustrates the currently used schema for active photosensitive pixel 4T, shared by 4 points, with an average of 1.75 shutter are used for each pixel.

Fig. 12 illustrates a schema for the active photosensitive pixel 4T, shared by 6 points, with an average of only 1.5 shutter are used for each pixel. This is the readout scheme is suitable for double-sided double-layer photosensitive device, in which the pixels are placed in a hexagonal pattern (see patent application (China) room 2008102172702 called "Multi-spectrum Photosensitive Devices and Methods for manufacturing the Same"), i.e., photosensitive diodes in both the upper and lower layers of all three components of the pixels in macropixel can share identical readout capacitor (FD) and identical schema 3T.

Fig. 13 illustrates a schema for the active photosensitive pixel 4T, shared by 8 points, with an average of only 1,375 shutter are used for each pixel. This readout scheme is suitable for double-sided double-layer photosensitive device in which chetyrehpolnye macropixel are placed in a square pattern, i.e., photosensitive diodes in both the upper and lower layers of all four pillars of the pixels in macropixel can share identical readout capacitor (FD) and identical schema 3T.

Fig. 14 shows the basic idea of the technology of combining different colors and a hybrid combination according to the present application, in which the first combined two pixels having different or same color in one macropixel (in the method for averaging or summation of signals), and then combine two adjacent pixel, the ima is the following one color. Fig. 14(a) is a schematic diagram showing a combination of the two columns of photosensitive devices based on the Bayer pattern, while Fig. 14(b) is a schematic diagram showing the simultaneous combination of two columns and two rows of photosensitive devices based on the Bayer pattern. In this paper, the combination of different colors formed by combining G and B or the combination of G and R; while hybrid combination is formed by mixing combinations of G and B, G and R, B and R, and G and G, because some of them are between one color (G and G), whereas others between different colors. After hybrid combining the image with the primary colors (RGB) Bayer pattern is converted into an image with more colors (CyYeMgG). In this drawing, the combination of G and B, G and R, B and R, and G and G are the first process of combining. The second process is implemented by combining simultaneous output values of Cy, Ye, Mg and G in various positions in the bus, and then it is combined with a method of combining one color or skip some pixels through the use of ways to skip lines or columns and read one after the other.

Fig. 15 illustrates a hybrid technology combining the agreement is but this application used in a more General combination of M rows and N columns (5×3, as shown in the drawing, i.e. in the combination of five rows and three columns). Many different cases, similar to Fig. 15, can be obtained by combining the methods of crossing or intersection of rows and columns. The combination of three rows and three columns can be performed by combining two rows and two columns when skipping one row and one column.

It should be noted that the pair of signals (Mg or G)placed in identical average position, is formed when cross-combining is carried out in the third and fourth lines. To simplify the combination of the second column, Mg or G can be viewed in its forward position, so as to maintain uniformity.

When the symmetry property of rows and columns, Fig. 15 can easily be extended to different combinations 3×5, 2×3, 3×2, 2×4, 4×2, 5×2, 2×5, 2×6, 6×2, 3×4, 4×3, 3×6, 6×3, 4×4, 4×5, 5×4, 4×6, 6×4, 5×6, 6×5, 6×6, 7×6, 6×7, 7×7, 8×8 and so on, More useful factors are combining 2×2, 2×4, 4×2, 4×4, 3×6, 6×3, 6×6, 4×8, 8×4 and 8×8, by means of which should be easy to maintain aspect ratio (width to length) of the image. Similarly, in this drawing, the combination of G and B, G and R, B and R, and G and G are the first process of combining. The second process is implemented by combining the simultaneity the temporal output values Cy, Ye, Mg and G in various positions in the tire, and then the process of combining according to the method of combining one color and skip inaccessible pixels between them (for example, the fifth row and the tenth column in the drawing). Missing color should no longer adhere to the following third process of combining and sampling, if the sensor has the function of the third process of combining and sampling.

Fig. 16 illustrates additional reducing scaling of images of 2×2, caused by the transformation matrix color space. Regardless, CyYeMgG image is the original image or an image derived from RGM-image on the basis of the principle Bayer through a hybrid method combining the present application, can be obtained for more reducing the scaling of images of 2×2, when CyYeMgG image is converted into a YUV image. The way to reduce scaling is that macropixel CyYeMgG regarded as the four pixels at a common point, so that it is converted to pixel (Y, U, V), and then YUV422 image (typically required for preview and JPEG/MPEG compression) is implemented by means of averaging adjacent (horizontal direction) of U and V pixels.

Fig. 17 illustrer is no excellent schema of the application, in which the opaque reading capacitor FD (for example, FD1 and FD2, shown in Fig. 1) is shared by the photosensitive pixels in odd and even rows. Switch TG1 is used to selectively move the charges of the photosensitive diode Gr in FD1. Similarly, switches TG2, TG3 and TG4 are also used to move the charge values R, B, and Gb in FD2, FD1 or FD2, respectively. Another switch TG5 is used to read the values of the capacitance of the read capacitor FD1 to FD2 (or FD2 in FD1) in the method of summation. Photosensitive pixels with this layout, you can use schema based on a four-point parallel sharing, as shown in Fig. 18. In this scheme the opacity required by the read capacitor FD, it is necessary to implement progressive scanning and interlaced scanning or reading with gaps as shown in Fig. 21.

Fig. 18 illustrates the sensing scheme is based on a four-point parallel sharing used for four-point matrix template macropixel of this application, in which each pixel uses two transistors. Although the scheme is not reading scheme based on the joint use of minimal closures,it has many advantages in some other areas of technology. One advantage is that during subdirectly a pixel value of Gr in the odd lines and the pixel value B in the even-numbered lines may be imposed in the way of summation by simultaneous opening TG1/TG3 or TG2/TG4, so that the signal increases, while the noise can be reduced. Similarly, the pixels in a diagonal line can be read using the methods of summation by controlling the time sequence to simultaneously open TG1/TG4/TG5 or TG2/TG3/TG5. Another advantage is that the interlaced reading or reading with gaps as shown in Fig. 21 may be implemented by storing the pixel values in the following line in FD during sampling of the full image.

Fig. 19 illustrates a schema-based restitching sharing used in double-layer photosensitive device having tragically hexagonal pattern macropixel according to the present application. In this scheme, the read capacitor FD1 is shared by three pixels in the top layer, while the read capacitor FD2 is shared by three pixels in the lower layer, and amplification and readout scheme is shared by three pixels in the top layer, and p is the means of three pixels of the lower layer. Way together use the read circuit through the upper and lower layer can simplify the design and to simplify the control logic of subdirectly. This circuit differs from the circuit according to Fig. 12 the fact that it reads the capacitor is not shared by the upper and lower layers, in order to make easier to make two-sided photosensitive devices.

Fig. 20 illustrates a schema-based vospitatelnogo sharing used in double-layer photosensitive device having chetyrehpolnye hexagonal pattern macropixel according to the present application. In this readout scheme of the readout capacitor FD1 is shared by four pixels in the upper layer, while the read capacitor FD2 is shared by four pixels in the lower layer, and amplification and readout scheme is shared by four pixels in the upper layer, and by four pixels of the lower layer. This circuit differs from the circuit according to Fig. 13 the fact that it reads the capacitor is not shared by the upper and lower layers in order to simplify the manufacture of bilateral photosensitive devices.

Obviously, two-sided two-layer photocasting the device four macropixel in the upper and lower layers may use the sensing scheme based on parallel use with double FD, it is shown in Fig. 18, respectively, so that the readout circuit for the upper and lower layers are relatively independent and can be read in interlace methods or methods with gaps to increase the speed of the shutter when shooting images with full resolution.

Fig. 21 illustrates a schematic diagram of the readout scheme the discretization shown in Fig. 17, which is used in the way interlaced readout (Fig. 21(a)) or the method of reading with gaps (Fig. 21(b)) during the sampling of the full image.

When the first row (GrRgGrR...) is read during interlaced readout in Fig. 21(a), each pixel value in the second row (BGBG...) is transferred into an empty FD after the value of the corresponding position in the first line read. I.e., when the pixel in column N in the first row is read, the pixel in column N-1 (or N-2 and so on) in the second line is transferred into vertically corresponding FD-region associated with the first and second rows. I.e., immediately after the first line, then read exactly the pixel values in the third line, instead of the pixel values in the second row, now stored in the FD, shared by the first and second rows. Similarly, during the readout of pixel values in the third line of the pixel values of the fourth row od is vremenno transferred to the FD region. In other words, all values of the pixels in the even-numbered rows are shifted to the buffer FD-areas up until the pixel values in the odd rows are not read completely. Finally, the pixel values of the even rows are read line by line sequentially from the buffer FD-regions.

When the first row (GrRgGrR...) is read during the read passes to Fig. 21(b), the values of the second row (BGBG...) are transferred to exempt FD after the values of corresponding positions in the first line read. I.e., when the pixel in column N in the first row is read, the pixel in column N-1 (or N-2 and so on) in the second line is transferred into vertically corresponding FD-region. After the first line, then reads a pixel value in the fourth line, other than pixellogo values of the third row, while a pixel value in the third row is transferred to the FD region. Identical, whereas the pixel values in the third row are read out, the pixel values of the fourth row are simultaneously transferred to the FD region. In other words, the rows are read according to the order 1, 4, 5, 8,..., 2, 3, 6, 7. One of the advantages in Fig. 21(b) is that the first half of the frame is still placed in the Bayer pattern and then the preview image thumbnails can be quickly obtained at the time of photographing according to the ways the U.

The way interlaced read or to be read passes to Fig. 21 differs from the way field scanning used in previous television system. The main difference is that the reading time of the second half of the frame stored in the buffer region is almost identical to the read time of the first half of the frame. Therefore, the speed of the shutter is doubled compared with line-by-line reading, while the situation of delay in one field (half frame) between odd and even fields caused by way of the field scanning in a television system, is not allowed. This situation is suitable for the case of capture one photo, non-continuous video recording.

This is a very effective way to increase the speed of the electric shutter during capture images through the interlace reading or reading with passes. For example, if the clock signal for reading pixels is set to 96 MHz and the number of pixels of the photosensitive crystal is 8 million, the speed of the shutter is (96/8)=12 frames/second or 1/12 of a second during the shooting of the full image. If you do interlaced scanning or reading with gaps shown in Fig. 19, one interesting frame of mcneven what about the increases to 24 frames/second or 1/24 of a second, ie, the rate is doubled. Shutter for shooting speeds up to 1/24 of a second, which means that the mechanical shutter in the module photography mobile phones can be omitted, while the mechanical shutter is needed for photography with the speed of 1/12 of a second, to prevent distortion of the image caused by shaking hands.

Fig. 22 illustrates the situation of a simplified processing for double-layer photosensitive device during subdirectory: in the first process of combining the method of combining or exclusion is used for pixels excessive colors of the upper and lower layers, and then reserved only color components necessary to restore the colors, for example, Cy, Mg (obtained by combining B and R, G and Ye. YUYV422-image obtained in the third process of combining, in which the method of converting the color space shown in Fig. 16, is used to convert the adjacent pixels CyYeMgG in pixels YUV-color, and two subdirectly in the horizontal direction are related to UV-components. The downsampled 2×2 is performed during this process. If the image is still too large, averaging one color in CyYeMgG instead of the method for the discretization of the full image is shown on the drawing, is performed in the second process before converting color CyYeMgG space to YUV color space.

During sampling the full image double-layer photosensitive device may ignore some of the pixels or to read out all pixels that must be processed by the internal processor. The amount of data to read all the pixels are doubled. Now, by the way interlaced scanning or reading with gaps shown in Fig. 18 and 22, the frame rate is doubled and then equal to the speed of an existing single-layer photosensitive device.

Fig. 22 is sufficient to illustrate the complexity and variety of two-layer or multi-layer photosensitive devices during subdirectory. Since there are thousands of options for distributions colors macropixels for two-layer or multi-layer photosensitive device, the greater number of appropriate options available for subdirectly. Next, it lists only a few ways to illustrate the essence of this application.

Fig. 23 illustrates another situation simplified processing for double-layer photosensitive device during subdirectory: macropixel CyYeMgB obtained through the summation (or averaging) of the pixels in the first process of combining. Four points are converted into YUV color through transformation the color in the third process of combining, and it is then downsampled 2×2. Of course, before color conversion can be performed by combining one color for macropixels CyYeMgG (by way of averaging of signals), instead of the method for the discretization of the full image, to execute a greater number of subdirectory during the second trial. It is obvious that macropixel CyYeMgB in the drawing can also be replaced by macropixels BRGB, similar to the Bayer pattern. Here CyYeMgB is used as the example, similarly, CyYeMgB, CyYeMgG, CyYeMgR can be used to obtain YUV or restore RGB, i.e. CyYeMgG is just a special case of CyYeMgX, where X can be R, G or B.

Fig. 24 illustrates another situation simplified processing for double-layer photosensitive device during subdirectory: adjacent pixels are combined (using the method of averaging or summation of signals in the horizontal direction in the first process of combining, and then combined the additional pixels are combined (using the method of averaging or summation of signals or ignore lines) in the vertical direction in the second process of combining. Combining horizontal and vertical directions can be run simultaneously through the proper management of the lie is authorized sequence. This kind of way of subdirectly is not only more versatile than the existing method of subdirectly, but also allows for a much better SNR.

Fig. 25 illustrates that a schematic block diagram of the basic system diagrams for reading and domain downsampling pixels, which implements the present application, which is used to describe the implementation for the various functional modules in a photosensitive devices for this application. The basic system contains will pixeloo matrix controller decoder address lines, the controller address decoder column control circuit discretization, the amplifier module and an analog-to-digital conversion, the conversion module and subdirectly colors and image processing, control module output, the control module main crystal (CC module of Fig. 25) and other possible modules. A pixel reading and downsampled achieved by appropriate control signals generated by controller decoder addresses of rows and columns (signal Row[i] the row selection signal RS[i] vector control lines, signal Col[j] column selection and the signal T[j] vector control columns, where i and j indicate the row number and column number, respectively). Interaction with other modules in the system, mainly istihaada by the control module the main crystal. Third, the combined sampling process, if any, should be performed in a module conversion and subdirectly colors and image processing.

Fig. 26 illustrates the relationship between each of the control signals shown in Fig. 25 (the row selection vector control lines, column selection, the control vector columns), and control signals in the respective photosensitive pixels through specific example (photosensitive pixel shown in Fig. 17). Fig. 26 illustrates the signals that are shared by the two pixels Gr and B (TG5 omitted)shown in Fig. 17, the signals Row[i] and Col[j] row selection are clear. In this scheme, the signal RS1 is reset and the control signal RS2 gate (TG1 or TG3) of the transfer signals are control lines. It should be noted that RS1 is shared by two strings, while the RS2 is used in each row (for example, TG1 belongs RS[i], while TG3 belongs RS[i+1]). However TG5 (which is omitted in Fig. 26), shown in Fig. 17 is a signal T[j] of the control columns. I.e., attempt to only perform string operations (identical to the operation for the pixels in the same row and column operations (identical to the operation for the pixels in the same column), but will not pixeloo is peratio (different operations for different pixels) to the maximum extent possible, in order to reduce the complexity.

Methods for sampling and subdirectory according to the present application is illustrated in the following embodiments, with reference to Fig. 25 and 26.

DETAILED description of the INVENTION

In multi-spectral photosensitive device according to the options the implementation of this proposal, various schemes for reading and subdirectory can be implemented through a scheme similar to the scheme shown in Fig. 25, containing: pixeloo matrix that includes many macropixel, the controller decoder address lines, the controller address decoder column control circuit discretization, the amplifier module and an analog-to-digital conversion, the conversion module and subdirectly colors and image processing, control module output, the control module main crystal (for example, CC-module in Fig. 25), and possibly other modules.

According to the needs of macropixel on the basis of four pixels or three pixels is first placed in a square or hexagonal patterns. These pixels can be active pixels, passive pixels, the pixels having the read capacitor (FD), or the pixel readout capacitor (FD).

The above process subdirectory is divided into first, second and optional third process to which binyavanga and sample rate. First, second and third blocks of combining these processes, respectively, are used in order to implement the above processes of combining and sampling. Of course, these blocks are modules of the device, separated simply from the point of view of functions. Physically, these functional blocks can be implemented in a single physical module functionally implemented in combination of multiple modules or integrated into the physical module. In short, the first, second and third blocks of the combination described only functionally in this document. Their description is not the intention to limit their physical implementation.

In particular, in the example as shown in Fig. 12, the controller decoder address lines and the controller address decoder columns are used to implement the function of subdirectly. The controller decoder address lines should show the two types of signal, i.e. the signal Row[i] select the line (one line in each row) and the signal RS[i] vector control lines (one or more lines in each row), where i denotes the row number. Similarly, the controller address decoder column should show the two types of signal, i.e. the signal Col[j] column selection (one line in each column) and the signal T[j] vector control columns (one or more lines in each column), where j on the mean number of the column.

Signal Row[i] string selection is used to select the line, while the signal Col[j] column selection is used to select a column. These are two of a set of relatively standard signals. Signal Row[i] string selection is an extension of the existing control signal CMOS lines (from line in each line to multiple lines in each row), while the signal T[j] vector control columns do not exist in some photosensitive CMOS devices, even if there is only one signal in a single column. Fig. 26 shows a specific implementation Row[i], RS[i], Col[j] and T[j] on the basis of photosensitive pixels, shown in Fig. 17, in which Row[i] is shared by two strings, while RS[i] includes signals RS1[i] (which is also a reset signal that is shared by two rows) and RS2[i] control lines (which is the control signal of the charge-transfer).

In this application you can select multiple rows, multiple columns or multiple rows and columns. Although multiple rows or multiple columns are selected simultaneously in some previous technologies (for example, patents (US) non 6801258B1, 6693670B1, 7091466B2, 7319218B2 and so on), time sequence and waveform selection lines and the signal of the column selection differ as a result of which their various ways of combining and sampling. For example, during the combining and sampling in Fig. 14(a) first row, first column and second row, second column of the first row are selected simultaneously. This situation never occurs in the way subdirectory in the prior art.

RS[i] and T[j] are used to control the reset, clearing to zero, the control photosensitive time, charge transfer, combination and reading of photosensitive pixels. There are many types of concrete implementations for RS[i] and T[j] due to the symmetry properties of the row and column. Signals TG1-TG5, Vb1-Vb4and so on, shown in Fig. 17, and the signals RS, S and SF, as shown in Fig. 18, can be included in RS[i] and T[j], and the present application should not be limited to the specific implementations of these signals.

More specifically, during subdirectory with any coefficients of the M×N (M≥2, N≥2), first executes the first process of combining and sampling, in which two rows or two columns or two rows and two columns are combined and is discretized, and then downsampled by M rows×N columns is performed based on the first process of combining and sampling.

The downsampled after the first process of combining and sampling, i.e., the second process of combining and sampling may be performed pose the STV or any combination of the following methods: automatic averaging of signals, displayed directly on the bus, skipping lines or skipping columns or sampling one element. However, the third process of combining and sampling, if any, may be met through one or a combination of the following two ways: color space conversion and the final scaling of digital images.

It is known that there are a lot of photosensitive pixels in the pixel matrix. Specifically for two-layer or multi-layer photosensitive devices there are many types and geometric distributions colors. Obviously, the first process of combining and sampling directed at many of the first combined pixel. Thus, during the first process of combining and sampling the color selection for combining the first combined pixel is different from the point of view by combining the colors of the pixel, comprising combining one color by combining different colors, hybrid combining (some pixels have the same color, while others have different colors) or selective elimination of redundant colors.

Color space conversion includes the conversion from RGB - in CyYeMgG-space conversion from CyYeMgG - in YUV-space is the conversion from RGB to YUV space.

It should be noted that the conversion from RGB - in CyYeMgG-space can be performed in the space of analog signals or digital space. Therefore, this conversion may be performed in any of the first, second or third process of combining and sampling. However, the conversion from CyYeMgG - in YUV-space conversion from RGB to YUV space can only be performed in the space of digital signals, i.e., in the third process of combining and sampling.

More specifically, Pixela matrix consists of many macropixels, each of which contains three or four basic pixel, while the base pixels are placed in a square pattern. The underlying pixels in macropixel can be passive pixels or active pixels 3T without FD or active pixels 4T with FD.

If the underlying pixels macropixel are active 4T pixels with FD, the read circuit also can use the 4-point sharing (Fig. 11), mode 6-point sharing (Fig. 12) and mode 8-dot sharing (Fig. 13).

More preferably each macropixel may consist of active pixels 4T, having two opaque FD, and readout scheme also can use the 4-pixellogo parallel joint is the sing (as shown in Fig. 18). Accordingly, photosensitive devices use the overlay method charge time by combining the colors of subdirectly with two rows or two columns or two rows and two columns for the first time. This kind of macropixel provides options for the next progressive scan and interlaced sampling or sampling with deletions of the full image.

For two-layer or multi-layer photosensitive device, in addition to a rich selection of colors in the first process of combining and sampling, where each macropixel may consist of active pixels 4T, having two opaque FD, reading scheme, moreover, you may use the 4-pixellogo parallel sharing (Fig. 18), mode 6-pixellogo parallel sharing (Fig. 19) or 8-pixellogo parallel sharing (Fig. 20). Accordingly, photosensitive devices use the overlay method charge time by combining the colors of subdirectly with two rows, or two columns or two rows and two columns for the first time.

It should be noted that the upper limit of improvement of SNR is NNtime to the Yes N signals are combined by applying the imposition of charges, while the upper limit of improvement of SNR isNonce, when N signals are combined by averaging signals. Secondly, when the discretization of the full images in a photosensitive device in which four points are shared by the two FD (or FD is shared by pixels in two rows), the mode progressive scan and interlaced readout can also be used in addition to normal mode progressive scan and line-by-line reading.

For example, during sampling of the full image in accordance with the requirements of the requested image area controller decoder address lines and the controller address decoder column, first, sequentially determine the values of Row[i] and RS[i] how high or low and, secondly, consistently specify values Col[j] and T[j] as high or low when negotiating through the device so that the desired value of the pixels (charge/voltage) can be displayed in the output bus (via a scheme of reading/writing) in accordance with the order of reading.

During subdirectory for each of the supported ratio of the sampling rate of M×N (through which the line should be reduced by M times, and a hundred the Betz must be reduced N times) according to the ratio of the sampling rate of M×N and the requirement for the image area, the controller decodes the address lines and the controller decodes the column addresses simultaneously set the values of all Row[i] and RS[i] lines, which must be combined according to each line of output as high or low, and then simultaneously set the values of all Col[j] and T[j] of the columns that are to be combined according to each output column as high or low, so that the values of (charge/voltage) of all the pixels must be combined, can be displayed in the output bus (via the read circuit in accordance with the order of reading. Meanwhile, if necessary, the controller decodes the address lines and the controller decodes the column addresses also perform the necessary operation skip rows or columns or eliminate redundant color according to the ratio of the sampling rate of M×N and the requirement for areas of the image.

For different ratios of sampling M×N, various colors can be obtained on the output bus at different points in time. Accordingly, other functional modules, such as module amplification and analog-to-digital conversion, the conversion module and subdirectly colors and image processing and control modules output may need to be coordinated accordingly. The overall management of this system can perform the I through the control module main crystal (CC module of Fig. 25). It should be noted that most of the modules except module amplification and analog-to-digital conversion and the pixel matrix, are the digital processing circuit, and thus can be easily implemented on the periphery of the device so that the interconnect photosensitive device is simplified.

The following is a more specific sequence of control signals in combination with the reading circuit shown in Fig. 26, and other modules photosensitive device shown in Fig. 25, while the read circuit shown in Fig. 26, is used by the photosensitive pixels shown in Fig. 17.

First, controls the reset and read: one simple way to control the reset is to reset Vb1 and Vb2, where Vb1 and Vb2 are the signals of the vector control lines. Another way is that FD1 and FD2 first reset (i.e., RS1 is set to zero in Fig. 26), and TG1 and TG2 are opened simultaneously (i.e., RS2 is set to the high level in Fig. 26)to remove the charges in Gr and R of the photosensitive pixel. Then RS1 is set to high level, while the RS2 is set to zero. When the radiation light photodiodes Gr and R then start the charge accumulation.

There are three ways to read the charges Gr. The first way is that TG1/RS2 ow and[i] appear directly charges Gr transferred to FD1 and then (after conversion from charge to voltage) reads the value of the charge Gr. The second method is that once the charge value Gr is read at the last stage of the first method, FD1 is reset and reads the charge (voltage) FD1 in reset in order to perform cross-discretization for the value of the charge reading Gr. The third way is that before reads the value of the charge Gr, FD1 first sampled reset. The third method does not provide such benefits, as the second method, because it fluctuates the value of Gr. Here, the signal Col[j] select the column corresponding to Gr, must be opened by the controller decoder column address so as to output the dimension of Gr (can be measured two times, one in reset) in the amplifier module and an analog-to-digital conversion.

According to the values of Row[i], Col[j] and RS2[i], module CC control of the main crystal can figure out the color of read pixels and perform the appropriate process for flowers. Different colors can be entered in different amplification schemes and run through various processes of analog-to-digital conversion, thereby obtaining a digital signal.

Digital signals of photosensitive pixels stored in the buffer and add the eno processed by the transform module and subdirectly colors and image processing. In the case of sampling the full image downsampled not performed, and, in General, the color conversion for the image sensors for a large matrix is not running. Therefore, module CC control of the main crystal can manage them accordingly in this mode so that the digital signals of the photosensitive pixels may be received directly in the module image processing instead of the processing module and subdirectly colors. After processing the images in a photosensitive devices digital signals can be output to the external interface of the photosensitive device through the output module.

During sampling of the full image, it should be noted mode progressive scanning and interlaced scanning or reading with passes. In this case, the control is reset, and the photosensitive time in odd and even rows can be done simultaneously. During interlaced readout after the pixels in even-numbered rows (the first row) is read completely, the controller decoder address lines not immediately reads the next line, but moves the pixels in the next odd-numbered row (the second row) in FD that are shared by the even lines, and then begins to read the third line. During the read gaps, if PE is the first row is numbered from 0, reading order of the rows in the first half of the frame is 0, 3, 4, 7, 8, 11, 12, 15,..., while reading order of rows of the second half frame is 1, 2, 5, 6, 9, 10, 13, 14,.... can Also be more complex orders. For example, the string that is not read during reading of the first half of the frame temporarily stored in the FD, which is used once, and must be read up until the last half of the frame is not read.

The difference between the progressive scan and interlaced read or to be read passes and the traditional way of field scan, adaptable in television receivers, is that the time sequence of pixels is entirely progressive in the way that progressive scanning and interlaced scanning or reading with gaps according to the present application.

It is more difficult during subdirectory, but it's possible that only a few coefficients subdirectly M×N are supported for a particular photosensitive device. Accordingly, module CC control of the main crystal, the controller decodes the address lines and the controller decodes the column addresses can consider only supported the coefficients subdirectly M×N. for Example, a photosensitive device with a resolution of 5 million pixels can be is tested only four cases of 2×2, 2×1, 4×4 and 8×8.

The second process of combining and sampling in General neither involves the imposition of charges, and usually apply the following three ways: automatic averaging of signals output directly into the tire, skipping lines or skipping columns or sampling one element. Three ways are traditional and simple and are known to specialists in this field of technology. Thus, their description is omitted. The third process of combining and sampling can be performed in the space of digital images through the use of technology scaling digital images, which is a relative standard. Below detail only the sequence of control signals in the first process of combining and sampling to do how to use the application more understandable.

For macropixels, as shown in Fig. 17, there are two ways of combining the first process of combination, one of which is combined with Gr B and the combination of R with Gb; and the other is combined with Gb Gr and the combination of R with B.

For the first type of combination according to the time sequence:

1. Time t0: RS1 corresponding FD1, as shown in Fig. 26, is set to zero (cleared) by the control of the EPA decoder address lines.

2. Time t1: TG1 and TG3 (RS2[i] and RS2[i+1]) are opened, while the charges of the photosensitive diodes (PD) Gr and B simultaneously transferred to FD1, respectively. Here, RS1 can be set equal to the high level.

3. Time t2: Row[i] and Col[j] open (assuming that Gr is the i-th row and j th column), the charge (voltage value) FD1 is displayed in the output bus.

4. Time t3: zero FD1 can be read to be used for correlated sampling.

All pixels in the i-th and (i+1)-howl lines can be simultaneously performed on the first two stages (i.e., at the moments t0 and time t1), and the combined pixels can be read sequentially in the third and fourth stages (i.e., in the moments t2 and time t3). Therefore, one pixel can be read per one clock pulse in the middle without a correlated sampling; otherwise, when performing a correlated sampling one pixel can be read in the calculation of the two clock pulse on average. This is done according to the priority of the pixel position. The type of combination can be used according to the following priority colors.

For the second method of combining time sequence is more complex. There are two ways of processing, one of them based on priority colors, i.e., on the combination and increments the organizations first Gr and Gb for the entire row and then on the combination of a and sample B and R, or in reverse order. This method is simple, and the time sequence of control signals is as follows:

5. Time t0: RS1 corresponding to FD1 and FD2, as shown in Fig. 17 and Fig. 26, is set to zero (cleared) by the controller decoder address lines.

6. Time t1: TG1 and TG4 (RS2[i] and RS2[i+1]) are opened, while the charges of the photosensitive diodes (PD) Gr and B simultaneously transferred to FD1, respectively. In this document RS1 can be set equal to the high level.

7. Time t2: TG5 offer, and charge FD2 is transferred to FD1.

8. Time t3: next Row[i] and Col[j] open (assuming that Gr is the i-th row and j-th column), and charge (voltage value) FD1 is displayed in the output bus.

9. Time t4: zero FD1 can be read to be used for correlated sampling.

All pixels in the i-th and (i+1)-howl lines can be simultaneously performed on the first three stages (i.e., at the moments t0, t1 and t2 time), and the combined pixels can be read alternately in the fourth and fifth stages (i.e., at the moments t0, t1 and t2 time). Therefore, one pixel can be read per one clock pulse in the middle without a correlated sampling; otherwise, when performing a correlated sampling one pixel can be read in the calculation of the two clock pulse on average. The method of reading violates natural the public order according to the positions of the pixel and require adjustments to the final processing. To maintain consistency, the first type of combination can be carried out according to the priority of colors.

The second procedure is based on the priority items: first is the combination and the discretization of the first Gr and Gb, and then combining and sampling the first B and R, and this is done repeatedly. The time sequence of this type of control signals is similar to the time sequence of the first processing method, while the sequential processing can be performed between pixels instead of parallel processing. I.e., the second combined pixel may not be processed in moments t0-t5 time during processing the first combined pixel. It requires a system clock signal with a higher frequency. Well, the number of pixels is reduced after subdirectly. Therefore, the frequency of the system clock signal may not be too high.

For the preferred scheme of this application during subdirectly correlated sampling may be omitted due to their limited benefits. Therefore, the above time sequence is simpler.

For the selected order of sampling pixels module CC in the management of the main crystal can control the amplifier module and an analog-to-digital conversion, respectively, to carry different colors through different amplifier circuit in the transform module and subdirectly colors and image processing, as well as in the control module output, so that different colors can be processed differently. A more detailed description is beyond the scope of this application.

Previous downsampled mainly performed between pixels of the same color and mainly achieved through the operations of averaging pixels and skip lines or skip columns. These methods may not be applicable for dual photosensitive devices or multiprocessing devices. How subdirectly proposed in this application can be performed by way of converting the color space between pixels of the same color or different colors. Alternatively, the method of subdirectly proposed in this application can be performed in a hybrid scheme (i.e., downsampled partially executed between some pixels of the same color and partially performed between other pixels of different colors). In addition, according to the combination of signals the imposition of charges proposed in this application, the advantage of summation N3signals can practically be achieved by combining only signals. Therefore, the method of subdirectly in this application should provide higher quality images compared to a typical method subdirectory in the prior art. In particular, when this application is used for double-layer photosensitive device or multi-layer photosensitive devices, a large number of simple and excellent way of subdirectly.

The above description is provided to illustrate the nature and scope of the present application by single-layer and double-layer photosensitive device and some active pixels 3T/4T. These specific conditions is not our intention to limit the present application. On the contrary, if this application is used for more complex structures, such as active pixels 5T/6T or multi-layer photosensitive device, the advantages are more obvious.
