The scope of the invention

The technical field to which the invention relates

The present invention relates to data processing used in display devices such as televisions and monitors, as well as in the imaging devices to create images in computer graphics, particularly to the diagram of the color correction performed by the correction of colors in these images, based on three colors, i.e. red, green and blue color, whereas the difference in the various imaging devices.

The level of technology

Traditionally, when the display color in accordance with the input color signal to a display device such as a monitor screen, the color tone, as a rule, is adjusted depending on the operation mode of the display device, so that the image having the desired color can be reproduced. The process of adjusting the color tone can be broadly divided into two processes, namely the process of the conversion table and the process matrix operations.

In accordance with the process table of the conversion image data corresponding to red color, green color and blue color (hereinafter referred to as R, G and B, respectively), are introduced so that the optimum image data, selected from the image data for R, G and B which have undergone the process of adjusting the color tone and stored in memory, such as persistent storage device or the like, can be displayed in response to input image data; tabular method of transcoding allows adaptation of any of the adjustable characteristics of the color tone and, thus, is advantageous for the realization of adjusting the color tone for good color reproduction. This traditional process, however, has the problem lies in the fact that the process was designed to be simple to save the data for each combination of image data which requires a large memory capacity, such as 400 M bits, and these problems remain even in the case of seal capacity memory in some continuous region; thus, it is difficult to integrate a high level (LSI) in this process, and this process has another problem associated with the fact that the system process is not flexible enough, to change the mode of the device, and the like.

On the other hand, the process of adjusting color tone using the method of matrix operations, it is designed so that the values (value) adjust the hue for output directly calculated on the basis of the luminance signal of alarms color contrast, Y, Cr and Cb, converted from the input R, G and B signals or the original input R, G and B signals. For example, there is a method of operation for the output signals R', G' and B', by multiplying the input R, G and B signals on the matrix coefficients, arranged in three rows and three columns. This formula can be expressed as given below:

This process of adjusting color tone using the method of matrix operations does not require a large memory capacity, which was discussed earlier in connection with the process table conversion, and therefore permits the use of a high integration level (LSI). Next, the process of adjusting the color tone can be flexibly adapted to change the operation mode using the corresponding adjustment of each of the elements a11-a33 matrix coefficients defined above in equation (1). As for the process of adjusting color tone using the method of matrix operations, the following are the links, for example Link 1 or Link 2.

Reference patent 2: tiled patent application No. 2003-223911

In the traditional process of adjusting color tone using the method of matrix operations is determined by the color obtained by mixing the input R, Di B signals, in order to calculate the amount of correction required for the correction of this shade. For example, as shown in Fig. 3 (in the case of the traditional process of adjusting the color tone), the specified color is divided into 6 color ranges, namely the red band, green band, blue band, blue band, purple band and yellow band, for fine adjustment of colors; however, this traditional method of color correction is not good enough, because the peripheral area of each color range are virtually unadjusted, as uncorrected range.

In addition, developed the traditional scheme for simultaneous adjustment of hue and white balance correction; however, in the case of such a conventional approach for adjusting the color tone of the white balance correction is performed by adjusting gains for R, G and B signals, and it is known that the use of such traditional schemes for white balance correction leads to deterioration of other colors. Moreover, as in the case of the above-mentioned color correction process, and in the case of adjusting the white balance, the final adjustment should be performed by the user, which is necessary to determine the extent necessary corrections, watching the state of the image on the screen of the display device; however, this traditional scheme is not intended to provide for each user the opportunity to exercise the necessary adjustments while watching the state of the image displayed on the screen before adjustment, so the user can make fine-tuning adjustments.

The present invention is proposed to solve such problems of the traditional process of color correction by creating a diagram of the color correction for each shade is designed not only to enable the user to perform color correction for each color for any given image without leaving any unadjusted ranges, but in order to make possible adjustment of the white balance without sacrificing other colors, as well as to enable the user to perform a desired color correction for each shade, watching the state of the image before the correction.

Moreover, the present invention is designed so that only the white color could be adjusted, without affecting other colors, unlike the case of using the traditional process of color correction, in which the gain for R, G and B signals are evenly adjusted for white balance correction. The AOC is e, in accordance with the present invention, the image may be divided into two parts so that the user can compare the effect of the correction applied to one part of the image, with the state of the unadjusted portion of the image. The implementation of the present invention will be described below with reference to relevant drawings.

In the description following the implementation of the basic fashion of correction is described as a broad fashion, while compensatory fashion of correction will be described as detailed fashion.

Figure 1 presents a block diagram illustrating the structure of the color correction for each color in accordance with the present invention. As shown in Fig. 1, the component red component, green component and blue color video signal (corresponding to R in G in B in Fig. 1), which signals representing the three colors are entered in the processor 11 gamma, as well as in the calculator 13 to highlight the range and calculate the adjustment values for a wide range calculator 14 to highlight the range and calculate the adjustment values for detailed range.

The output processor 11 gamma is introduced into the matrix processor 12 for performing color correction process using the matrix coefficients, arranged in three rows is three columns, similar to the aforementioned equation 1, and is output through the output terminal. In this case, 9 of the matrix of coefficients, which is the matrix coefficients corresponding to a matrix of 3 rows by 3 columns, calculated by the calculators 30-38 matrix of coefficients denoted DT11N, DT21N, DT31N, DT12N, DT22N, DT32N, DT13N, DT23N and DT33N respectively. The process for obtaining DT11N using matrix calculator 30 will be described below.

The calculator 13 to highlight the range and calculate the adjustment values for a wide range determines which of the three ranges, namely, red band, green band and blue band corresponds to the combination of the entered R, G and B signals in a broad fashion, basic fashion, and outputs the Ws, which is the signal selection to a wide selector 18 correction factor calculator 30 matrix coefficient and also calculates the size of the adjustment wide fashion ΔW for output to the circuit 20 multiplication calculator 30 matrix coefficient through the circuit 16 logical And.

The calculator 14 to highlight the range and calculate the adjustment values for detailed range determines which of the six ranges, namely the red band, yellow band, green band, blue band, blue and purple range, corresponds to the combination of CC is given to R, G and B signals in a detailed fashion, which is a compensatory fashion correction; the calculator to highlight the range and calculate the adjustment values for detailed range not only displays Zs, which is the signal selection, fine-grained selector 19 of the coefficient correction unit 30 processing matrix coefficient, but also calculates the adjustment value ΔZ in a detailed fashion for output to the circuit 21 multiplication arithmetic unit 30 matrix coefficient through the circuit 17 logical And.

The processor 15 data for half of the graphic screen is for entering into it V sync signal, which signal vertical sync input, and the signal of the blank screen, which is the signal blanking display device, and input of a signal for instructing the data processing half of the image from the controller 28. The controller 28 outputs a control signal for processing the data for half of the image in a data processor, half of the image in response to a user instruction; in response to the instruction to process data for half of the image processor 15 data half of the image determines the assigned position for processing in the image based on the V sync signal and the signal of the blank screen, and outputs a high signal for the Asti image, which will be adjusted, and the signal of low level for the part not requiring correction, respectively, to circuits 16, 17 and 24 logical And. Circuits 16, 17 and 24 logical And respectively configured to output input to the following for their elements only when the signal from the data processor, half of the image is a signal of high level.

Wide selector 18 correction factor arithmetic unit 30 matrix coefficient selects the correction factor in a wide fashion on the basis of the Ws signal from the calculator 13 to highlight the range and calculate the adjustment values for a wide range of output, which is the Wt signal, to the circuit 20 multiplying at a later stage. At this stage a wide selector 18 correction factor is intended for input of the correction coefficients, that is, W1S [1], W2S [1] and W3S [1] signals, which are correction coefficients corresponding to each of the shades in a wide fashion, from the controller 28, and the correction factor corresponding to the selection signal of the selection Ws is selected from these signals. Moreover, the controller 28 is intended for input elements of adjustments, such as hue, saturation, gain for R, G and B signals, etc. that have been set by the user using a personal computer etc. via Ter the Inal 29 input external information, and the correction factor for each tone is generated on the basis of this input.

Scheme 20 multiplication multiplies ΔW signal representing the correction value input from the calculator 13 to highlight the range and calculate the adjustment values for a wide range through the circuit 16 logical And Wt signal is introduced as a correction factor introduced from a broad selector 18 correction factor to generate ΔWt signal for output to the circuit 22 adding at a later stage.

Detailed selector 19 correction factor arithmetic unit 30 matrix coefficient selects the correction factor in a detailed fashion on the basis of Zs signal from the calculator 14 to highlight the range and calculate the adjustment values for detailed range; the selected correction factor in a detailed fashion displays, as Zt signal to the circuit 21 multiplying at a later stage. At this stage, the correction coefficients, Z1S [1], Z2S [1], Z3S [1], Z4S [1], Z5S [1] and Z6S [1] signals related respectively to different shades in a detailed fashion, entered from the controller 28, are detailed in the selector 19 correction factor and the correction factor corresponding to the shade selected by the signal selection Zs, is selected from these signals. These 6 possible coefficient the correction generated in the controller 28 in accordance with various shades, based on information from the terminal 29 to the input of external information, in a manner similar to what was described with reference to a broad fashion.

In scheme 21 multiplication ΔZ signal representing the correction value input from the calculator 14 to highlight the range and calculate the adjustment values for detailed range through the circuit 17 logical And, multiplied by the Wt signal, which is a correction factor introduced from detailed selector 19 correction factor, in order to generate ΔZt signal for output to the circuit 22 adding at a later stage.

The calculator 23, the correction values of the white ΔW signal representing the correction value input from the calculator 13 to highlight the range and calculate the adjustment values for a wide range through the circuit 16 logical And, and ΔZ signal representing the correction value input from the calculator 14 to highlight the range and calculate the adjustment values for detailed range through the circuit 17 of the logical And is used to generate ΔWH signal representing a correction quantity for white, for output to the circuit 24 logical And at a later stage. In scheme 24 logical AND ΔWH signal is output to the circuit 25 multiplication at the next stage only when the signal is l from processor 15 data half of the image is a signal of high level.

In the scheme of 25 multiplication ΔWH signal entered from the calculator 23 correction values of white through the circuit 24 logical And multiplied by WH [1] signal, which is a correction factor used to correct the white signal from the controller 28 to generate ΔWHt signal for output to the circuit 26 of the addition at a later stage. WH [1] signal, which is a correction coefficient used for correcting white, is a signal to enter only in the diagonal elements of the matrix 3x3 coefficients and adjusts the white balance by implementing subtle adjustments to the diagonal elements, initially having the value [1].

In figure 22 adding ΔWt signal from the circuit 20 of the multiplication is added to ΔZt signal from the circuit 21 multiplication to generate ΔWZt signal for output to the circuit 26 of the addition at a later stage; in scheme 26 adding ΔWZt signal is folded ΔWHt signal from the circuit 25 multiplication to generate ΔWZHt signal for output to the circuit 27 of the addition at a later stage; in scheme 27 adding ΔWZHt signal is added to the ST [1] signal, which is the static coefficient from the controller 28 to generate DT11N signal, which is the matrix coefficient for output to the matrix processor 12 at a later stage.

When DT11N signal is generated in the arithmetic unit 30 matrix coefficient, although the NGOs are generated matrix coefficients in the other arithmetic units 31-38 matrix coefficients for output to the matrix processor 12 at a later stage; in the matrix processor 12 processing matrix is applied to the output from the CPU 11 gamma using these 9 matrix of coefficients and displays the results processing matrix. However, since the system for calculating correction values of white in the arithmetic unit 30 matrix coefficient applies only to the diagonal elements of the matrix 3x3, arithmetic blocks 34 and 38 of matrix coefficients generate DT22N and DT33N signals, respectively, reflecting the adjustment of white, while the other arithmetic units of the matrix of coefficients of the generating matrix coefficients which are not intended for adjustment of white.

The effect of such a system structure will be described with reference to Fig. 1 and Fig. 4. R in G in B in signals, respectively, entered into a scheme of color correction color, have the tint values, as shown in Fig. 4(a)-4(c), respectively, and these signals are entered into the calculator 13 to highlight the range and calculate the adjustment values for a wide range calculator 14 to highlight the range and calculate the adjustment values for detailed range.

In the calculator 13 to highlight the range and calculate the adjustment values for a wide range of the conditional expression represented in figure 4(d)-4(h)are applied to input R in G in B in the signals for the population ranges, while the correction value ΔW is calculated using conditional expressions, given in figure 4(d). In this case, when ΔW is obtained using the expressions given in figure 4(e), generated triangular pulses that differ from those shown on the chart, but they are fixed to the trapezoidal waveform shown on the same graph, by applying a limiter to such triangular pulses. More precisely, when the maximum brightness level is set equal to 255, the limiter is applied at the point where the brightness level is equal to 32 or so, thereby maintaining a constant value of a portion corresponding to the brightness value that is higher than this level. Thus, through the application of the limiter difference in the correction values between the low brightness and high brightness can be maintained at an approximately constant level, and therefore can be implemented color correction, is not subject to misalignment shades.

In the process 14 selection range and calculate the adjustment values for the detailed range of the conditional expression represented in figure 4(f)-4(h)are applied to input R in G in B in the signals for the selection of their ranges, while the expression defined in figure 4(g), is used to obtain correction value ΔZ for detalizirovano what about the range by means of calculation. As in the case of obtaining the correction value ΔW for a wide range of the waveform is adjusted to the trapezoidal shape shown in the diagram, using a delimiter.

The calculator 23, the correction values of the white correction value for white is calculated for output on the basis of the correction value ΔW for a wide range and correction value ΔZ for detailed range. More precisely, the shape of the signal obtained by the conversion of the high level of the waveform for signal ΔW, shown in Figure 4(e), refers to the low level, and its highest value is limited by the limiter, and the waveform obtained by contacting the high level of the waveform for signal ΔZ shown in Fig. 4(g), refers to the low level, and its highest value is limited by the limiter, become available to the waveform that results from the addition of these two forms, as shown in Figure 4(i), could be taken as a correction value for the white ΔWH.

In the selector 18 correction factor for a broad fashion the correction factor selected Ws signal is multiplied by the correction value ΔW for a wide range to generate ΔWt; drilled selector 19 correction factor the correction factor selected Zs signal is multiplied by a corrective led the rite ΔZ for detailed range to generate ΔZt; corrective quantity for white ΔWH is multiplied by the correction factor white for generating a signal ΔWHt; these three signals, namely, ΔWt, ΔZt and ΔWHt sequentially formed to generate DT11N, which is the matrix coefficient of the first row and first column to output matrix processor 12 at a later stage.

Thus, the color correction is performed using both signals, ΔWt signal reflecting the correction value for a wide range, and ΔZt signal reflecting the correction value for the detailed range so that the peripheral region in the range of tint left unadjusted in the same fashion, could be corrected by correction in a different fashion, thus allowing for color correction, leaving no unadjusted areas. Further, for adjusting the white balance ΔWHt signal reflecting the correction factor white only for the diagonal elements of the matrix of coefficients is generated additionally, in order to allow adjustment of the white balance without affecting other colors, in contrast to the traditional process of white balance correction, designed for uniform adjustment gain R, G, and B signals.

Moreover, in order to make the color is greccio and the white balance correction in accordance with the present invention is more efficient than the traditional process, the processor 15 half of the image is performed so that the image could be divided into two parts at any desired border to the above-mentioned correction process applied to one part of an image, while the other part of this image remained unchanged by saving the output signal from the circuits 16, 17, 24 logical And at the zero level in accordance with the instruction from the CPU 15 half of the image, so that half of the image remained resistant to svecokarelian and correction of white balance, whereby the user can adjust only half of the image, in order to be able to compare state adjusted half of the image with the unadjusted half of the image to allow the user to adjust the image more finely.

The above implementation is done so that corrective value was determined on the basis of the R, G and B signals, which are input signals, and correction values are determined on the basis of these three signals, but the present invention is not limited to such implementation. For example, input signals can be yellow (Y), cyan (C), Magenta (M) signals, in order correction in a wide fashion millibyte made on the basis of the three ranges, the respective Y, C and M, the unadjusted correction ranges can be supplemented by a correction in a detailed fashion and Vice versa, so that could be obtained effects correction, similar to the pre-implementation, in which color was divided into three ranges of R, G and B.

Moreover, in the above implementation, the hue is divided into three ranges during color correction in a broad fashion, while the hue is divided into six ranges during color correction in a detailed fashion so that any uncorrected range could be extended by another correction range. However, the method of separation of hue is not limited to the above method; for example, in the case of correction in a wide fashion shade can be divided into six ranges, and correcting in a detailed fashion, shade can be divided into twelve bands or any other number ranges, provided that the color correction process is designed so that any uncorrected range could be extended by another band and to the purpose of the present invention can be achieved. Similarly, another implementation is designed so that the hue is divided into three ranges, that is, R, G, and B correction in a wide fashion, and the hue is divided into three range is on, that is, the Y, C and M for correction in a detailed fashion, whereby it may be made the color correction process so that any uncorrected range can be supplemented by another correction range for color correction, not leaving any unadjusted range.

FIELD: physics; measurements.

SUBSTANCE: present invention pertains to systems of marking images with a watermark, and particularly to detecting a watermark in an information signal. Proposed here is a detector (100) of presence of a watermark in an information signal. The information signal is correlated with the expected watermark (Wi) for each of set of relative positions of the information signal relative the watermark, so as to obtain a set of correlation results (64). A metric which, is a root-mean-square value, is calculated for the group of results (64). The metric is compared with a threshold value h, which indicates the group representing presence of a correlation peak. The metric can be calculated for groups, created in each position in the result buffer (64). Alternatively, the metric can be calculated only for the group, which is identified as the possible correlation peak.

EFFECT: increased efficiency of detecting a watermark in an information signal.
