Summary of the invention

Problem solved with the help of the invention

When the display device to display a stereoscopic image on the display screen is designed to allow the user to visually recognize the stereoscopic image in interaction with an external device, such as polarization glasses and liquid crystal shutter spectacles, the amount of light coming into the eye of the user can be reduced, in accordance with the type of the external device. For example, when the display device displays a stereoscopic image in a manner of alternately displaying an image for the right eye (the image represented by the image signal for the right eye and the image for the left eye (the image represented by the image signal for the left eye) over time, and the user is watching the image using points with zhidkokristallicheskoi�them shutter, then it happens that the amount of light approaching in the user's eyes through the glasses with liquid crystal shutter may be reduced. In the above case, the image observed by the user as a whole becomes dark due to the insufficient amount of light, therefore, the user may receive eye fatigue.

The display device controls the light source and control of the brightness gradient method, which is an example of preventing the reduction of the amount of light entering the user's eyes. However, when the light source control and management of the brightness gradient without constraints is on the side of the display device, for example, the area of the image, which should be dark, it becomes too bright, and the author of the work (e.g., movie or game) relating to the image displayed on the display screen, may not be reflected in the image observed by the user. Therefore, in the above case, even when it is possible to prevent a decrease in the amount of light entering the eyes of the user when the image signal is displayed on the display screen, there is no certainty that high image quality (high image quality from the point of view that the author works�Denia reliably reproduced so on) sufficiently implemented,

Therefore, there is no certainty that a high quality image sufficiently implemented, as in how to prevent reduce the amount of light entering the user's eyes, even in the case when the use of related technology.

In light of the above, it is desirable to provide a new and improved device processing the image signal transmitting device, a method of processing image signal, program, and system for processing image signal, capable of realizing high-quality image�s and at the same time to prevent the reduction of the amount of light entering the eye of the user when the image signal is displayed on the display screen.

of the present invention;

3. The program according to the embodiment of the present invention;

Approach to the solution of the task according to the embodiment of the present invention

Approach to the problem of obtaining high-quality images, according to an embodiment of the present invention is described before describing the configuration of each device included in the processing system image signal (which in some cases�enoeda to as "system 1000 signal processing image"), according to the embodiment of the present invention.

As described above, when using method of preventing reduction of the amount of light entering the user's eyes and related technologies, the image displayed on the display screen and observed by the user, may not adequately reflect the intent of the author.

Then, in the system 1000 of processing the image signal transmitting device (in some cases, is referred to as "transmitting device 100") according to embodiment of the present invention, which serves for transmission of the image signal, generates setting information for each predetermined segment of the image signal on the basis of the image signal to be transferred, and transmits the setup information together with the image signal. In a further signal including an image signal and setting information for each predetermined segment of the image signal transmitted by the transmitting device 100, sometimes together referred to as "transmission signal".

In the system 1000 signal processing image processing device of the image signal (in some cases, is referred to as "the device 200 signal processing image"), according to an embodiment of the present invention, receives a signal �imaging, and installation information handles the received image signal and selectively controls the brightness gradient and/or to control the light source of the display device based on the adopted installation information.

Meanwhile, in the system 1000 of processing the image signal according to embodiment of the present invention, the transmitting device 100 may transmit an audible signal relating to the audio data corresponding to the image represented by the image signal together with the image signal, the device 200 signal processing image processing audio signals.

The process relating to the transmission of the tone signal transmitting device 100 and process related to the processing of the audio signal in the device 200 of the signal processing of the image, not further described.

Here, although there is a digital signal, such as a stream of binary signals, and as described in this description, the image signal according to embodiment of the present invention, options are not limited by the above description, and perhaps the use of the analog signal. Further, in the example described a case in which an image signal according to embodiment of the present invention is a digital signal. In addition, the image, p�zestawienie image signal, according to the embodiment of the present invention may be a moving image (flat image/ stereoscopic image), and may be a still image (flat image/ stereoscopic image).:

The specified segment of the image signal according to embodiment of the present invention is, for example, completed in time segment of the signal image. Although the quality of a given image segment can be used, for example, a frame, one segment of the image in interlaced scanning, one segment images with progressive scanning or the like, according to an embodiment of the present invention, options are not limited to the above description. For example, a given segment of the image signal according to embodiment of the present invention may be a set of frames.

Installation information according to embodiment of the present invention, includes mounting type information of the image installation information for gamma correction and/or setup information brightness. In this description, although the transmitting device 100 may transmit the setup information to the image type setting information to the gamma correction and setup information brightness, with�publicly embodiment of the present invention, for example, as a single installation information (data), options are not limited to the above description. For example, transmitting device 100 may transmit the setup information to the image type setting information to the gamma correction and setup information brightness separately. In a variant implementation of the present invention, the case where the transmitting device 100 transmits various pieces of information as one of the installation information, and a case in which it transmits them separately, as described above, are described under the assumption that the "setting information includes setting information of the image type, installation information, gamma correction, and/or setup information brightness".

Installation information type of image, according to an embodiment of the present invention, is information that is used to determine whether an image signal for stereoscopic image. The installation information of the image type used by the device 200 of processing the image signal to selectively perform a process of displaying a stereoscopic image. Example installation information type of image, according to an embodiment of the present invention, will be described later.

Next, set�full-time information gamma correction, according to the embodiment of the present invention, is information that is used to determine the value of gamma correction for the image signal. Installation information gamma correction is used by the device 200 of processing the image signal to control the brightness gradient. Example installation information gamma correction, according to an embodiment of the present invention, will be described later.

Further, the setup information brightness, according to an embodiment of the present invention, is information that is used to determine the brightness for each part of the display screen. Setup information brightness is used by the device 200 of processing the image signal to operate a light source of a display device. Example setup information brightness, according to an embodiment of the present invention, will be described later.

According to this description, there is a highlighted area obtained by dividing the image represented by the image signal, in many areas, for example, such as described above, a portion of the display screen. Although in this case, for example, obtained by the division to each pixel of the display device constituting the display screen is highlighted above �the gialo, options are not limited by the above description, and such a region may be a region having a plurality of picture elements. In addition, the above-described part of the display screen may be part corresponding to the control device of the display device, light emission of which is controlled by the device 200 of processing of the image signal using the signal brightness control as described below.

More precisely, in the system 1000 signal processing image processing device of the image signal selectively controls the brightness gradient and/or control the light source of the display device based on the adopted installation information, so that when the image represented by the image signal is displayed on the display screen, the brightness of the image area with a low level of brightness becomes higher.

Fig.1-4 are explanatory diagrams to illustrate the General ideas about the principle of obtaining high-quality image according to the embodiment of the present invention.

(a) the Case in which the device 200 signal processing image does not exercise control of the brightness gradient and the light source control of the display device based on the installation information.

Fig.1 illustrates the p�emer gamma correction device 200 of processing image signal and also illustrates an example of the image signal, when the device 200 signal processing image does not exercise control of the brightness gradient and the light source control of the display device based on the installation information. Fig.1A shows an example of gamma characteristics in the transmitting device 100, and Fig.1 represents an example of a function gamma correction device 200 of the signal processing of the image. Fig.1C shows an example of the image signal after gamma correction device 200 of the signal processing of the image. Further, Fig.2 illustrates an example when the image represented by the image signal against which performed gamma correction illustrated in Fig.1 and displayed on the display screen in the device 200 of the signal processing of the image.

As shown in Fig.1A-1C, when the device 200 signal processing image does not exercise control of the brightness gradient and the light source control of the display device based on the installation information, the image signal processed by the device 200, the signal processing of the image becomes the image close to the image represented by the image signal transmitted by the transmitting device 100 using gamma correction (Fig.2).

In this case, the gamma correction device 200 processing whitefish�Ala image is performed, for example, using the following formula 1.

(Formula 1):

Y=255·(X/255)1/γ

X in formula 1 is an image signal which must be processed, a Y in the formula 1 represents the image signal after gamma correction. In addition, in the formula 1 represents the value of the gamma correction. Although in this description the formula 1 represents an example of the gamma correction when the brightness is divided into 255 levels, options are not limited to the above description.

The device 200 signal processing image sets the amount of gamma correction to the value which corresponds to the gamma characteristic of the transmitting device 100 (e.g., when an image signal is transmitted using radio waves of television broadcasting, the value of y is set at 2.2), thus obtaining an image signal shown in Fig.1C.

(b) the Case in which the device 200 of processing the image signal controls the brightness gradient and the light source control of the display device based on the installation information.

Fig.3 illustrates an example of the image signal, when the device 200 of processing the image signal controls the brightness gradient and/or control the light source of the display device based on the adopted installation information. Further Fi�.4 illustrates an example, when the image represented by the image signal shown in Fig.3, is displayed on the display screen in the device 200 of the signal processing of the image.

As shown in Fig.3, the device 200 of processing the image signal controls the brightness gradient and/or control the light source of the display device based on the adopted installation information so that the brightness of the area with low brightness becomes higher. The device 200 of processing the image signal controls the brightness gradient and/or control the light source of the display device so that the brightness of the area with low brightness becomes higher, and accordingly, the image displayed on the display screen becomes the image brightness is higher than that of the image shown in Fig.2, for example, as illustrated in Fig.4.

An example of a method of controlling the brightness gradient in the device 200 of the signal processing of the image

The device 200 signal processing controls the image brightness gradient by setting the values of the gamma correction function used in the gamma correction based on the installation information of gamma correction, which included, for example, adopted in the installation information.

Fig.5 is an explanatory diagram illustrating a CR�measures installation information gamma correction, generated by the transmitting device 100, according to an embodiment of the present invention. Here Fig.5 illustrates an example installation information gamma correction in accordance with the easy to use video information (VUI), as defined in ISO/IEC 14490-10.

The transmitting device 100 sets the value of the gamma correction parameter "transfer_characteristics" shown in Fig.5, is able to determine a photoelectric transfer function. Although in this description the transmitting device 100 directly sets the value of the gamma correction, for example, "transfer_characteristics=2.2" and "transfer_characteristics=2.8", options are not limited to the above description. For example, the VUI, in accordance with ISO/IEC 14490-10 applicable definition content becomes possible when set to "transfer_characteristics=2". Therefore, the transmitting device 100 can also set the value of gamma correction, for example, such as 2.4 GHz, by setting the parameter "transfer_characteristics=2", as described above.

At the same time, it is obvious that the installation information to the gamma correction, according to an embodiment of the present invention is not limited to the example illustrated in Fig.5.

The device 200 of processing of the image signal can control the brightness gradient based on the installation inform�tion by performing gamma correction, using the value of gamma correction set in the setup information to the gamma correction, which is incorporated into the installation information.

At the same time, a method of controlling the brightness gradient in the device 200 of processing the image signal according to embodiment of the present invention is not limited to the above description. For example, the device 200 of processing the image signal according to embodiment of the present invention can selectively adjust the gain of the image signal for each picture element on the basis of information gain to determine the amount of gain that is included in the installation information, after receiving the image signal shown in Fig.1C, obtained by using gamma correction.

An example of a method of controlling a light source of a display device in the device 200 of the signal processing of the image

The device 200 of the signal processing generates the image signal brightness control to control the brightness of each part of the display screen in the display device capable of displaying an image on the display screen for each part on the basis of the setup information brightness contained, for example, in the received installation information. Then remove�STV 200 processing of the image signal transmits the generated signal to control the brightness of the display device, capable of displaying the image on the display screen.

Light emission in the display device is controlled according to the signal brightness control by sending a signal to control the brightness of the display device. Consequently, the device 200 of processing of the image signal can transmit a signal to control the brightness of the display device on the basis of the setup information brightness included in the installation information, thus controlling the emission of light in the light source of the display device.

Although in this description, the display device receiving the control signal, the brightness generated by the device 200 of processing the image signal may be provided, for example, in device 200, the signal processing of the image options are not limited to the above description. For example, the device 200 of the signal processing of the image may transmit the generated signal to control the brightness of the display device, which is an external device. When the device 200 signal processing image provided by the display device (corresponding to the display, which will be described later), the device 200 of processing of the image signal is used as a display device.

Although the quality of the display device in accordance with an embodiment is�the implementation of the present invention can be used for example, a liquid crystal display (LCD) having a light source capable of emitting light for each area corresponding to each element of the image or multiple image elements, options are not limited to the above description. For example, a display device in accordance with a variant implementation of the present invention may be a display device are self-illuminating type, without a separate light source, such as an organic electroluminescent display (also referred to as an OLED display or a display with organic light emitting diodes). Further, in the example described a case where the device 200 of the signal processing generates the image signal brightness control to control the emission of light in the light-emitting source provided in the display device.

Fig.6 is an explanatory diagram illustrating an example of the setup information brightness generated by the transmitting device 100, according to an embodiment of the present invention. In this description of Fig.6 illustrates an example setup information brightness, according User_data_unregistered SEI (supplemental enhancement information - additional information about the improvement), defined in ISO/IEC 14496-10.

Here the parameter "MacroBlock_ID" shown in Fig.6 is informatiile determine the macroblock (example highlighted area) on the image represented by the image signal. The numerical value given in the order and in ascending order from top left to bottom right, set to "MacroBlock_ID", for example, shown in Fig.6. Therefore, the device 200 of the signal processing for the image that receives the setup information brightness, can clearly recognize the position horizontally and vertically using the above numerical values.

In addition, the transmitting device 100 sets the information of the average brightness level for the macroblock (example selection) corresponding to each "MacroBlock_ID" shown in Fig.6 in the parameter "AverageJLumaJevel" shown in Fig.6. Therefore, the device 200 of the signal processing for the image that receives the setup information brightness, can definitely set the brightness level that should be set for each macroblock (example selection), so it is possible to generate the control signal of brightness corresponding to the setup information brightness for each part of the display screen.

At the same time it is obvious that the setup information brightness, according to an embodiment of the present invention is not limited to the example illustrated in Fig.6.

The device 200 of the signal processing of the image may generate a signal to control the brightness for each�the second part (each highlighted area) of the display screen, using the information of the brightness level for each of the allocated area specified in the setup information brightness, incorporated into the installation information for transmission to the display device, to thereby control the emission of light in the light source of the display device based on the installation information. At the same time it is obvious that a method of controlling a light source of a display device in the device 200 of processing the image signal according to embodiment of the present invention is not limited to the description above.

In the system 1000 of processing the image signal control of the brightness gradient and/or light source control of the display device is, for example, as described above, in the device 200 of the signal processing of the image. Therefore, in the system 1000 of processing of the image signal can be prevented reduce the amount of light coming into the eye of the user when the image is processed by the device 200 of processing of the image signal is displayed on the display screen of the display device.

In addition, in the system 1000 signal processing image device 200 of processing the image signal controls the brightness gradient and/or to control the light source of the display device based on the installation information, p�rezannoy, the transmitting device 100, as described above. That is, in the device 200 of processing the image signal according to embodiment of the present invention, the control of the brightness gradient and/or to control the light source of the display device is not freely based on a received image signal, as in the case of use of a way of preventing the reduction of the amount of light entering the user's eyes.

Therefore, in the system 1000 of processing of the image signal the possibility that the image displayed on the display screen and observed by a user insufficiently reflects the intent of the author of the work may be advanced.reduced and thus, can be realized high image quality.

At the same time, it is obvious that the device 200 of processing the image signal according to embodiment of the present invention is additionally capable to carry out the above-described control operations by the user using the operating device is provided, for example, in the device 200 of processing image signal, in addition to the control of the brightness gradient and/or control the light source of the display device based on the adopted installation information. In the case of using the above-described configuration, the signal processing system image with�publicly embodiment of the present invention can reflect the user's intent, who is watching the image, at the same time reflecting the intention of the author of the work, on the image displayed on the display screen and observed by the user.

As described above, in the system 1000 of the signal processing of the image transmitting device 100 transmits an image signal and setting information for each predetermined segment. The device 200 signal processing image then processes the received image signal, and selectively performs the control gradient, brightness, and/or to control the light source in the display device based on the adopted installation information. Therefore, in the system 1000 of the signal processing of the image is possible to realize a high quality image, while avoiding reducing the amount of light entering the eyes of the user, when displaying the image signal on the display screen.

At the same time, although the above-described case in which the device 200 of processing image signal, which part of the system 1000 of processing image signal, processes the received transmission signal, options are not limited to the above description. For example, the device 200 of processing the image signal according to embodiment of the present invention can save the data content (data, comprising data corresponding to signals�Lou image and installation information), corresponding to the received transmission signal, the data medium (for example, in the memory device that will be described later).

The implication here is that the direct reception of the signal transmission related to 500 radio television broadcasting, means the reception of radio waves 500 television broadcast by each device, such as device 200 of processing image signal and the receiving device 300. In addition, it is accepted. what indirect reception of signal transmission related to 500 radio television broadcasting in the device 200 of processing the image signal indicates reception of the transmission signal transmitted from an external antenna that receives radio�alno 500 television broadcasting by using the processing device 200 of the image signal or reception of the transmission signal, for example, through the receiving device 300. Also, it is assumed that the indirect reception of signal transmission related to 500 radio television broadcasting, the receiving device 300, means the reception of the transmission signal transmitted from an external antenna that receives radio waves 500 television broadcasting, for example, through the receiving device 300.

The transmitting device 100, the device 200A processing image signal and the receiving device 300 are connected to each other through a computer network 600 (or directly). Furthermore, the device 200 In the processing image signal and the receiving device 300 are connected to each other via a connection interface 650. The implication here is that the term "connect" according to the embodiment of the present invention means, for example, that the device is in link state (or entered in the connection state).

For example, the connection interface 650 may be a universal serial bus (USB) interface, using the D-terminal, and an interface that uses optical digital audio terminal.

Meanwhile, although in Fig.7 shows an example in which the transmitting device 100 performs transmission of the image signal through the airwaves 500 television broadcast and the transmission image signal through a computer network 600 is not limited to the above description. The transmitting device 100 according to the embodiment of the present invention can transmit an image signal through the airwaves 500 television broadcast and/or transmit an image signal through a computer network 600.

As shown in Fig.7, the device 200 of the signal processing of the image may receive the transmission signal transmitted from the transmitting device 100 through the receiving device 300, and can receive the transmission signal without the use of a receiving device 300.

Gave�e describes the configuration of each device forming the system 1000 signal processing of the image. In addition, hereinafter, an example configuration for the reception of the transmission signal without the use of a receiving device 300 (device 200A processing image signal), and configuration to receive the transmission signal through the receiving device 300 (the device 200 In the processing image signal), is described as an example of the configuration of the device 200 of the signal processing of the image.

The transmitting device 100

Fig.8 is an explanatory diagram for illustrating the configuration of a transmission device 100 according to the embodiment of the present invention. The transmitting device 100 in Fig.8 module 102 processing frame format, the installation module 104, module 106 to generate a transmission signal and a transmitting module 108.

In addition, the transmitting device 100 may be, for example, is provided with a controller (not shown), a permanent storage device (ROM, not shown), random access memory device (RAM, not shown), a storage device (not shown), the operational module with which the user of the sending device 100 can control (not shown), a display device that displays various screens on a display screen (not shown), and similar devices. The transmitting device 100 coedine�t the above-mentioned components, for example, using a bus as a data transmission channel.

Here, the controller (not shown) consists of a MPU (microprocessor), various processing circuits and similar components, for example, to control the transmitting device 100 as a whole. In addition, the controller (not shown) may be used, for example, as a module 102 processing frame format, the installation module 104, module 106 for generating the transmission signal.

Permanent storage device (ROM, not shown) stores control data such as program and arithmetic parameter used by the controller (not shown). Random access memory (RAM, not shown) temporarily stores a program executed by a controller (not shown), and similar data. Although as a storage device (not shown) may be used in magnetic recording media such as a hard disk and a nonvolatile memory such as electrically erasable programmable permanent memory (EEPROM), flash memory, magnetoresistive random access memory (MRAM), ferroelectric random access memory (FeRAM) and random access memory based on phase transition (PRAM), options are not limited to the above description.

Although the operational module (not shown) may be used �oborotnyu switch, for example, like a button, a button to control the cursor and rotary selector switch, or a combination of these components, options are not limited to the above description. Although the quality of the display device (not shown) may be used, e.g., liquid crystal display or an organic electroluminescent display, options are not limited to the above description. In addition, the transmitting device 100 can be attached to an operation input device (e.g. keyboard and mouse) and display device (e.g. external display) serving as an external device to the transmitting device 100.

The module 102 processing frame format converts an image signal to be transmitted in a predetermined frame format corresponding to the transmission signal.

Here as subject to transfer to the image signal processed by the module 103 of the processing frame format may be used, for example, an image signal obtained by forming the image transmitted from the device forming the image, such as a camera, but options are not limited to the above description. For example, the transferable image signal processed by the transmitting device 100, according to the embodiment is p�effect of the present invention, may be the image signal received from an external device through a computer network 600 or similar, and may be the image signal based on the data content stored in the storage device (not shown).

Although in Fig.8 shows that the module 102 processing frame format introduces two image signal, options are not limited to the above description. For example, when an image signal that is injected into the module 102 processing format of the frame is a flat image, then enter any one of the image signals shown in Fig.8. That is, the module 102 processing frame format processes the image signal corresponding to the stereoscopic image (when you type two image signal) and an image signal corresponding to a flat image (when you enter one image signal). In addition, the number of image signals input from the module 102 processing frame format, correspond to the number of input image signals.

The setting module 104 sets the setting values, which must be set in the setup information of the image type, installation information gamma correction and/or setup information brightness, on the basis of the image signal output from the module 102 obrabativaet frame image signal, subject to transfer). Then the setup module 104 transmits the setup information of the image type, the installation information for gamma correction and/or setup information brightness, which set each setting value, the module 106 for generating the transmission signal.

Meanwhile, the transmitting device 100 according to the embodiment of the present invention, the setup module 104 may transmit each setting value module 106 generating the transmission signal, and a module 106 for generating the transmission signal can generate the setup information of the image type, the installation information for gamma correction and/or setup information brightness. Further, in the example described a case in which the setting module 104 generates the setup type information of the image installation information for gamma correction and/or setup information brightness for the transmission module 106 for generating the transmission signal.

Although the setting module 104 sets, for example, both or either of the installation values for installation in installation information gamma correction and installation values for installation in the setup information brightness in addition to a setup value for setting in the setup information of the image type, the invention is not limited in�Eden above description. For example, there is a possibility that the installation module 104 does not process related to the installation values for installation in installation information gamma correction and setup information brightness based on an operational signal corresponding to a user operation transmitted from the operating unit (not shown), and information determining not to perform the process included in the image signal.

Although the setting module 104 sets, for example, the setting value corresponding to data determined in advance of installation values for installation in installation information gamma correction and setup information brightness, the invention is not limited to the above description. For example, the installation module 104 can selectively connect information in which the setting value is set based on an operational signal corresponding to a user operation transmitted from the operating unit (not shown).

Further, in the example described a case in which the setting module 104 sets the setting values are to be installed in the installation information of the image type, installation information gamma correction and setup information brightness.

An example of the installation process in the installation module 104

Fig.9 JW�makes a block diagram of the sequence of operations, showing an example of the installation process in the installation module 104 of the transmission device 100, according to an embodiment of the present invention. In the following description it is assumed that the installation process, as shown in Fig.9, is performed by the transmitting device 100.

The transmitting device 100 determines whether the image signal that should be transmitted, the stereoscopic image (step S100). Here, although the transmitting device 100 determines that the image signal to be transmitted represents the stereoscopic image, for example, when processing a plurality of image signals, the invention is not limited to the description above.

When in step S100 it is determined that the image signal to be transmitted represents the stereoscopic image, the transmitting device 100 sets the setting value installation information type of the image on the stereoscopic image (step S102). In addition, when the evaluation result in step S100 is not set, the image signal to be transmitted represents the stereoscopic image, the transmitting device 100 sets the setting value installation information type of the image on a flat image (step S104).

Fig.10 is an explanatory �hemou, illustrating an installation example of type information image generated by the transmitting device 100, according to an embodiment of the present invention.

When in step S100 it is determined that the image signal to be transmitted represents the stereoscopic image, in step S102, the transmitting device 100 sets the flag "3D_flag" shown in Fig.10, which is a flag denoting whether the stereoscopic image is set to the state indicating the stereoscopic image. Further, when the evaluation result in step S100 is not set, the image signal to be transmitted represents the stereoscopic image, in step S104, the transmitting device 100 sets the flag "3D_flag" shown in Fig.10, in a state indicating a flat image (the state, not indicating the stereoscopic image). Although the transmitting device 100 sets the flag "3D_flag" shown in Fig.10, for example, in "I" and "O" when the image signal is, respectively, the stereoscopic image and the flat image, the invention is not limited to the description above.

Further, when in step S100 it is determined that the image signal to be transmitted represents the stereoscopic image, the transmitting device 100 us�stopped setting values of various elements of information, related to the image signal to be installed in the installation information of the image type, for example, on the basis of the image signal to be transferred, and the contents of the process performed in the module 106 for generating the transmission signal.

Although in this case as the information set, the transmitting device 100 is used, the flag denoting, for example, a frame or a field ("Frame_flag" in Fig.10), the flag indicating the format of the stereoscopic image ("3D_video_format in Fig.10), and a flag indicating whether the image signal of the image signal for the right eye or the image signal for the left eye ("Current_image_is_L" in Fig.10), the image is not limited to the above description. For example, transmitting device 100 may set various pieces of information relating to the stereoscopic image processing device 200 of the signal processing of the image which receives the installation information of the image type, in addition to the flags "3D_pair_Image", "Lefthand_side_is_L" and "Top_is_L" shown in Fig.10.

Furthermore, the device 200 of the signal processing of the image which receives the installation information, including the installation information of the image type shown in Fig.10, can unambiguously determine whether an image signal to be processed, stereoscopics�e image on the basis of the flag "3D_flag" set in the setup information of the image type. Therefore, when it is determined that the image signal to be processed represents the stereoscopic image, the device 200 of the signal processing of the image may selectively perform processing for displaying a stereoscopic image for the image signal on the basis of various information elements installed in the installation information of the image type.

At the same time, it is obvious that the installation information of the image type according to the embodiment of the present invention is not limited to the example shown in Fig.10.

An example of the installation process in the installation module 104 of the transmission device 100 is again described with reference to Fig.9. When setting value for setting the information of the picture type set in step S102 or S104, the transmitting device 100 determines the average brightness for each of the allocated area on the basis of the image signal (step S106).

When in step S106, for each selected area is determined by the average brightness value obtained statistical information on average values of the brightness of selected areas (step S108). Although in this case the frequency distribution of the average values of the brightness of selected areas is determined, for example, as a result�Tata statistical processing in step S108, this is not limited to the description above.

When in step S108 the obtained statistical information on average values of the brightness of selected areas of the display screen, transmitting device 100 determines whether the number of allocated areas, the average brightness value is not greater than a predetermined value, less than the first threshold value (step S110). Although in this case the values defined in advance, can be used as a set value related to the average brightness value, the first threshold value and second threshold value, which will be described later (first threshold > second threshold), the invention is not limited to the above description. For example, the above values can be appropriately set based on an operational signal corresponding to a user operation transmitted from the operation unit (not shown).

When in step S110 it is determined that the number of allocated areas, the average brightness value is not greater than a predetermined value, less than the first threshold value, the transmitting device 100 considers that the image represented by the image signal is generally quite bright, and sets the first setting values in the setup information schemes�-correction and setup information brightness (step S112).

Here as a first distribution value, according to an embodiment of the present invention is used, for example, setting value, not allowing the device 200 of processing the image signal to control the brightness gradient and the light source control of the display device based on the installation information. More specifically, the transmitting device 100 sets the value of gamma, which must be set in the setup information to the gamma correction, for example, the value of 2.2. In addition, the transmitting device 100 sets the information of the average brightness level that should be set in the setup information brightness, for example, the value corresponding to the average brightness value obtained, for example, in step S106. At the same time, the value set by the transmitting device 100 as a first distribution value and the type of setting, not limited to the above description. For example, transmitting device 100 may set the setting values, which must be installed in the different information elements constituting the setup information to the gamma correction shown in Fig.5, and in various information elements constituting the setup information brightness shown in Fig.6.

When in step S114 it is determined that the number of allocated areas; the average brightness value is not greater than a predetermined value, greater than or equal to the second threshold value, the transmitting device 100 considers that the image represented by the image signal, there is a dark area and second sets setting values in the setup information to the gamma correction and setup information brightness (step S116).

Here as the second setting values according to the embodiment of the present invention is used, the set data that does not allow a device 200 of the signal processing of the image, for example, to control the brightness gradient based on the installation information, but allowing, for example, that device to control the light source of the display device. More specifically, the transmitting device 100 sets the value of the gamma correction to�e must be set in the setup information to the gamma correction, for example, a value of 2.2. In addition, the transmitting device 100 sets the information of the average brightness level that should be set in the setup information brightness, for example, to a value larger than the value corresponding to the average brightness value obtained, for example, in step S106. At the same time, the value set by the transmitting device 100 as the second setting values, and the type of setting values are not limited to the above description. For example, transmitting device 100 may set the second setting values setting value that allows the device 200 of processing the image signal to control the brightness gradient based on the installation information, as well as allowing him to control the light source of the display device.

In addition, when in step S114 is not determined that the number of allocated areas, the average brightness value is not greater than a predetermined value, greater than or equal to the second threshold value, the transmitting device 100 considers that in the image represented by the image signal, there is a larger dark area and third sets setting values in the setup information to the gamma correction and setup information brightness (step S 118).

The transmitting device 100 may set the setting values, which must be set in the setup information of the image type, installation information gamma correction and installation information of brightness by performing the process, for example, shown in Fig.9. At the same time, the installation process in the installation module 104 perejaume� device 100 according to the embodiment of the present invention is not limited to the example, shown in Fig.9. For example, although Fig.9 shows a configuration in which the transmitting device 100 performs the installation process using two predetermined thresholds, the invention is not limited to the above description, the transmitting device 100, according to an embodiment of the present invention can perform the installation process by setting the adjusting value according to a number of threshold values+I", using one or more thresholds.

An example configuration of the transmission device 100 is again described with reference to Fig.8. The module 106 for generating transmission signal generates a transmission signal based on the image signal transmitted from the module 102 processing frame format, installation information of the image type, installation information gamma correction and setup information brightness transmitted to the docking module 104. Then the module 106 for generating transmission signal transmits the generated transmission signal to the transmitting module 108.

Although there's a module 106 for generating the transmission signal consists of encoder 110 to encode the image signal on the basis of a predetermined rule and the multiplexer 112 to output the transmission signal based on the image signal and installation information encoded by the encoding device�Twomey, 110, the invention is not limited to the description above.

Transmitting module 108 transmits the transmission signal transmitted from the module 106 for generating the transmission signal.

Although here in Fig.8 shows a configuration in which the transmitting module 108 is provided with a first transmitting module 114 to transmit the transmission signal through a broadcast radio wave 500 and the second transmitting module 116 to transmit the transmission signal through a computer network 600, the invention is not limited to the above description. For example, a transmitting device according to the embodiment of the present invention may be provided with one of two modules: a first transmitting module 114 or the second transmitting module 116.

Although the first transmitting module 114 is, for example, a modulator 118, and a radio frequency transmitter 120, the invention is not limited to the above description. Although the second transmitting module 116 is, for example, the module 122 processing Protocol and interface 124 to connect to a computer network 600, the invention is not limited to the description above.

The transmitting device 100 can generate the setup information for each specified segment of the image signal on the basis of the image signal to be transferred for transmission of the image signal and setting information, for example, through�Ohm configuration shown in Fig.8. At the same time, it is clear that the configuration of the transmission device according to the embodiment of the present invention is not limited to the configuration shown in Fig.8.

Although here, as the storage device 202 is used, for example, magnetic recording media data, such as a hard disk and nonvolatile memory such as flash memory, the invention is not limited to the description above.

The device data storage 202 stores various data such as the data content corresponding to the received transmission signal, the data content that is not dependent on a received transmission signal, the information for performing the process and various applications. Although here in Fig.11 shows an example in which data 240 with the content corresponding to the received transmission signal, and information 242 for performing the process are stored in the device data storage 202, the invention is not limited to the above description. For example, the device 200 of processing the image signal according to embodiment of the present invention can store the information to perform a process on the recording media data separately from the device data storage 202, for example such as the aforementioned permanent storage device.

Here is information to run� process according to the embodiment of the present invention is the information for example, to selectively control the brightness gradient based on the installation information, the light source control of the display device based on the installation information and the process for displaying a stereoscopic image according to the embodiment of the present invention.

More specifically, the receiving module 204 transmits the image signal to the first module 206 processing of the image signal and transmits the setup type information of the second image module 212 of the signal processing of the image. In addition, the receiving module 204 transmits the setup information to the gamma correction module 208 gamma correction and transmits the setup information brightness controller 210 brightness.

An example of a configuration of the receiving module 204

At the same time, it is obvious that the configuration of the receiving module provided in the device 200 of processing the image signal according to embodiment of the present invention is not limited to the configuration shown in Fig.12.

Again returning to the example of the first configuration of the processing device 200 of the image signal is described with reference to Fig.11.

More specifically, the receiving module 302 transmits the image signal to the module 304 of the processing of the image signal and transmits the setup information to the module 306 of the connection.

Here the receiver module 302 can have a configuration similar to the configuration of the receiving module 204 provided in the device 200A signal processing images, such as shown in Fig.12, but the invention is not limited to the description above.

The module 304 of signal processing image processes the image signal transmitted from the receiving module 302, and transmits the processed image signal module 306 of communication.

Therefore, using the transmission device 100 and the device 200 signal processing image processing system image signal capable of�high image quality at the same time without reducing the amount of light entering the eyes of the user when the image signal is displayed on the display screen.

In addition, in the system 1000 of the signal processing of the image transmitting device 100 selectively transmits the setup information corresponding to the image type (plane/stereoscopic image) of the transmitted image signal, the device 200 of the signal processing performs image process based on the installation information. Therefore, the user watching the image corresponding to the image signal processed by the device 200, the signal processing of the image, can see the image with the same brightness level when the display screen displays a flat image, and when the stereoscopic image is displayed.

In addition, in the system 1000 of the signal processing of the image transmitting device 100 sets the setting value to be set in the setup information on the basis of the average brightness value for each selected area, for example, as shown in Fig.9, and the device 200 of the signal processing performs image process based on the installation information. Therefore, in the system 1000 signal processing image compatibility exists at a visual level image�, displayed on the display screen, in that case, when you need every management option in device 200 of processing the image signal, and when the control is not necessary.
