[0001] The present technology relates to an information processing system and a program, and in particular to an information processing system and a program that are capable of performing color correction processing on an image on a display device even when a display control device that controls the display of a display device consisting of multiple display units arranged in a tiled pattern does not have a color correction function.

[0002] In recent years, large-sized LED (Light Emitting Diode) displays configured by arranging a plurality of display units in a tiled pattern have become widespread (see, for example, Patent Document 1).

[0005] However, not all display control devices for large LED displays have a color correction function. Therefore, there is a demand for a method that can perform color correction processing on images displayed on a large LED display even when the display control device for the large LED display does not have a color correction function.

[0006] The present technology has been developed in consideration of such circumstances, and makes it possible to perform color correction processing on the image of a display device even when the display control device that controls the display of a display device consisting of multiple display units arranged in a tiled pattern does not have a color correction function.

[0015] 1. First Embodiment Configuration Example of Display System FIG. 1 is a diagram showing a configuration example of a display system including a video transmission device as a first embodiment of an information processing system to which the present technology is applied.

[0016] 1 is composed of a video transmission device 11, an LED controller 12, and an LED display 13. In the display system 10, the video transmission device 11 performs color correction processing on video data based on temperature data representing the temperature of each pixel detected by the LED display 13, and an image is displayed on the LED display 13 based on the video data after the color correction processing.

[0017] Specifically, the video transmission device 11 (information processing system) is configured, for example, by a personal computer. The video transmission device 11 acquires temperature data of the LED display 13 (display device) for each frame from the LED controller 12 (display control device). The video transmission device 11 acquires frame-by-frame video data of the video to be displayed on the LED display 13. For each frame, the video transmission device 11 performs color correction processing on the video data based on the temperature data and temperature characteristic data representing the temperature characteristics of the chromaticity and luminance of the LED display 13. The video transmission device 11 supplies the video data after color correction processing for each frame to the LED controller 12.

[0018] The LED controller 12 controls each of the multiple display units (display sections) arranged in a tiled pattern that make up the LED display 13, and displays an image corresponding to the image data supplied from the image transmission device 11 on the entire screen of the LED display 13 for each frame. The LED controller 12 acquires temperature data for each pixel from each display unit of the LED display 13 for each frame, and supplies the temperature data of all the display units to the image transmission device 11 as the temperature data of the LED display 13.

[0019] The LED display 13 is a large LED display consisting of multiple display units (cabinets) arranged in a tiled pattern, and is arranged perpendicular to the ground as a video wall. Each display unit of the LED display 13 is equipped with a temperature sensor (temperature detection device) that detects the temperature of each pixel of that display unit on a frame-by-frame basis. The LED display 13 supplies temperature data representing the temperature of each pixel detected by the temperature sensor to the LED controller 12 for each display unit.

[0020] 1, the number of LED controllers 12 is one, but there may be more than one. For example, there is a limit to the number of display units that can be controlled by one LED controller 12. Therefore, if the number of display units that make up the LED display 13 exceeds the number of display units that can be controlled by one LED controller 12, multiple LED controllers 12 are provided. Each LED controller 12 then controls a share of the number of display units that it can control.

[0021] In this case, each LED controller 12 acquires temperature data of the display unit it controls from the display unit and supplies the data to the video transmission device 11. The video transmission device 11 then acquires temperature data of the entire LED display 13 by acquiring the temperature data of the display unit controlled by that LED controller 12 from each LED controller 12. In this case, too, the video transmission device 11 performs color correction processing on the entire video data based on the temperature data of the entire LED display 13. Therefore, compared to when each LED controller 12 individually performs color correction processing on the video data to be displayed on the display unit it controls based on the temperature data of the display unit it controls, it is possible to perform color correction processing more uniformly across the entire screen of the LED display 13.

[0022] <Example of Display Unit Arrangement> FIG. 2 is a diagram showing an example of the arrangement of the display units in the LED display 13 of FIG.

[0023] As shown in Fig. 2, the LED display 13 is configured by arranging display units 31 in a tiled pattern. In the example of Fig. 2, the LED display 13 is made up of 72 display units 31, i.e., 6 (rows) x 12 (columns), but this number can be any number. The display units 31 are configured by arranging pixels 31a, each of which is made up of red, green, or blue LEDs, in a matrix.

[0024] <Configuration Example of Video Transmission Device> FIG. 3 is a block diagram showing a configuration example of the video transmission device 11 of FIG.

[0025] The video sending device 11 in FIG. 3 includes a temperature acquisition unit 51 , a video acquisition unit 52 , a storage unit 53 , a color correction processing unit 54 , and a transmission control unit 55 .

[0026] The temperature acquisition unit 51 acquires temperature data of the LED display 13 for each frame supplied from the LED controller 12 in FIG. 1, and supplies the data to a color correction processing unit 54 .

[0027] The video acquisition unit 52 acquires video data for each frame of the video to be displayed on the LED display 13. This video data is stored, for example, in a server (not shown) and provided via a wired or wireless transmission medium such as a local area network, the Internet, or digital satellite broadcasting. The video data may also be stored in the storage unit 53. The video acquisition unit 52 supplies the acquired video data to the color correction processing unit 54.

[0028] The storage unit 53 stores temperature characteristic data of the luminance and chromaticity of the LED display 13 .

[0029] The color correction processing unit 54 performs color correction processing on the video data supplied from the video acquisition unit 52 for each frame, based on the temperature data supplied from the temperature acquisition unit 51 and the temperature characteristic data stored in the storage unit 53. The color correction processing unit 54 supplies the video data after the color correction processing to the transmission control unit 55.

[0030] The transmission control unit 55 controls the video data after color correction processing, which is supplied from the color correction processing unit 54 , to be transmitted to the LED controller 12 .

[0031] <Example of Temperature Data> FIG. 4 is a diagram showing an example of temperature data of the LED display 13. As shown in FIG.

[0032] In Fig. 4, the temperature of each pixel 31a represented by the temperature data of the LED display 13 is written within that pixel 31a. In the example of Fig. 4, the resolution of the LED display 13, i.e., the number of pixels, is 3840 x 2160, but in Fig. 4, for the sake of simplicity, the temperatures of only some of the pixels 31a of the LED display 13 are shown.

[0033] Here, if the position of the pixel 31a that is the ith from the left and the jth from the top in the LED display 13 is (i,j) (i,j are integers equal to or greater than 1), in the example of Fig. 4, the temperature of the pixel 31a at position (1,1) is 30.6°C. The temperature of the pixel 31a at position (1,2) is 30.1°C. In the example of Fig. 4, the temperature data of the LED display 13 represents the temperatures of 3840 x 2160 pixels 31a from the pixel 31a at position (1,1) to the pixel 31a at position (3840,2160).

[0034] <Example of Temperature Characteristic Data of Brightness of LED Display> FIG. 5 is a diagram showing an example of temperature characteristic data of brightness of the LED display 13. As shown in FIG.

[0035] In Fig. 5, the horizontal axis represents the temperature [°C] of the LED display 13, and the vertical axis represents the ratio of the luminance [nit] to the luminance [nit] at a reference temperature. The reference temperature is the temperature of the LED display 13 assumed when generating the video data for the video to be displayed on the LED display 13, and is 32°C in the example of Fig. 5. As shown by the solid line in Fig. 5, the temperature characteristic data of the luminance of the LED display 13 is data that represents the correlation between the temperature of the LED display 13 and the ratio of the luminance at that temperature to the luminance at the reference temperature.

[0036] Based on this brightness temperature characteristic data, the color correction processing unit 54 performs brightness correction processing to correct the brightness of the color correction processing by multiplying the brightness of each pixel of the video data by a ratio corresponding to the temperature of the pixel 31a corresponding to that pixel.

[0037] <Example of Temperature Characteristic Data of Chromaticity of LED Display> FIG. 6 is a diagram showing an example of temperature characteristic data of chromaticity of the LED display 13. In FIG.

[0038] 6, the horizontal axis represents the temperature [°C] of the LED display 13, and the vertical axis represents the amount of deviation from the chromaticity x or y of the reference temperature. In the example of FIG. 6, the reference temperature is 32°C.

[0039] As shown by the solid line in Fig. 6, the temperature characteristic data of the chromaticity x of the LED display 13 is data that represents the correlation between the temperature of the LED display 13 and the amount of deviation of the chromaticity x at that temperature from the chromaticity x at the reference temperature. As shown by the dotted line in Fig. 6, the temperature characteristic data of the chromaticity y of the LED display 13 is data that represents the correlation between the temperature of the LED display 13 and the amount of deviation of the chromaticity y at that temperature from the chromaticity y at the reference temperature.

[0040] The color correction processing unit 54 performs a chromaticity correction process that corrects the chromaticity of each pixel of the video data based on the temperature characteristic data of the chromaticity x and y, by adding a deviation amount corresponding to the temperature of the pixel 31a corresponding to that pixel to the chromaticity of that pixel.

[0041] <Explanation of Video Transmission Processing> Fig. 7 is a flowchart illustrating the video transmission processing by the video transmission device 11 of Fig. 3. This video transmission processing is performed, for example, in units of frames of the video to be displayed on the LED display 13.

[0042] In step S11 of FIG. 7, the temperature acquisition unit 51 acquires temperature data of the LED display 13 supplied from the LED controller 12, and supplies the data to the color correction processing unit .

[0043] In step S12 , the image acquisition unit 52 acquires image data of the image to be displayed on the LED display 13 and supplies the image data to the color correction processing unit 54 .

[0044] In step S13, the color correction processing unit 54 performs color correction processing on the video data acquired in the processing of step S12, based on the temperature data acquired in the processing of step S11 and the temperature characteristic data stored in the storage unit 53. The color correction processing unit 54 supplies the video data after the color correction processing to the transmission control unit 55.

[0045] In step S14, the transmission control unit 55 controls the color-corrected video data obtained as a result of the processing in step S13 to be transmitted to the LED controller 12. As a result, a video based on this color-corrected video data is displayed on the LED display 13. After the processing in step S14, the video transmission processing ends.

[0046] As described above, in the video transmission device 11, the temperature acquisition unit 51 acquires temperature data of the LED display 13, and the video acquisition unit 52 acquires video data of the video to be displayed on the LED display 13. Then, the color correction processing unit 54 performs color correction processing on the video data based on the temperature data and temperature characteristic data, and the transmission control unit 55 controls so that the color-corrected video data is transmitted to the LED controller 12. Therefore, even if the LED controller 12 does not have a color correction function, it can perform color correction processing on the video to be displayed on the LED display 13. As a result, it is possible to display high-quality video on the LED display 13 in which color changes due to temperature have been corrected.

[0047] Although the LED display 13 is arranged only in a direction perpendicular to the ground as a video wall, it may also be arranged in a direction parallel to the ground as a ceiling.

[0048] <Another Example of LED Display Arrangement> FIG. 8 is a diagram showing an example of the arrangement of LED displays in this case.

[0049] The LED display 70 in Fig. 8 is composed of a wall display 71, which is a large LED display arranged perpendicular to the ground, and a ceiling display 72, which is a large LED display arranged parallel to the ground. The wall display 71 is composed of a plurality of display units 71a arranged in a tiled pattern. The ceiling display 72 is composed of a plurality of display units 72a arranged in a tiled pattern.

[0050] The display units 71a and 72a may be the same or different types. If the display units 71a and 72a are different types, the storage unit 53 stores temperature characteristic data of chromaticity and luminance for each type. The color correction processing unit 54 then performs color correction processing on the video data of the video to be displayed on the wall display 71 based on the temperature characteristic data of the display unit 71a and the temperature data of the wall display 71. The color correction processing unit 54 also performs color correction processing on the video data of the video to be displayed on the ceiling display 72 based on the temperature characteristic data of the display unit 72a and the temperature data of the ceiling display 72.

[0051] In the first embodiment, the LED controller 12 acquires the temperature data in units of frames, but the temperature data may be acquired in units of multiple frames or at a predetermined timing. For example, since the temperature of the LED display 13 changes depending on the image being displayed on the LED display 13, the display time, the ambient temperature, etc., the LED controller 12 may acquire the temperature data at a timing corresponding to the change.

[0052] 2. Second Embodiment Configuration Example of Display System FIG. 9 is a diagram showing a configuration example of a display system including a video transmission device as a second embodiment of an information processing system to which the present technology is applied.

[0053] 9 includes a video transmission device 111, an LED controller 112, an LED display 113, and a thermography camera 114. In the display system 110, the temperature is detected by the thermography camera 114, not by the LED display 113.

[0054] Specifically, the video sending device 111 (information processing system) differs from the video sending device 11 in that the video sending device 111 acquires temperature data of the LED display 113 (display device) for each frame from a thermographic camera 114. Otherwise, the video sending device 111 is configured in the same manner as the video sending device 11.

[0055] The LED controller 112 (display control device) differs from the LED controller 12 in that it does not acquire temperature data from the LED display 113, but is otherwise configured in the same manner as the LED controller 12.

[0056] The LED display 113 differs from the LED display 13 in that it does not have a temperature sensor, but is otherwise configured in the same manner as the LED display 13.

[0057] The thermographic camera 114 (temperature detection device) detects the temperature of each pixel of the LED display 113 on a frame-by-frame basis by photographing the LED display 113, and generates temperature data representing that temperature. The thermographic camera 114 supplies the temperature data for each frame to the video transmission device 111.

[0058] The number of LED controllers 112 may be plural, similar to the number of LED controllers 12 .

[0059] As described above, the video sending device 111 performs color correction processing on the video data of the video to be displayed on the LED display 113 based on the temperature data and temperature characteristic data generated by the thermographic camera 114. The video sending device 111 then controls the video data after the color correction processing to be transmitted to the LED controller 112. Therefore, even if the LED controller 112 does not have a color correction function and the LED display 113 does not have a temperature sensor, the video data of the video to be displayed on the LED display 113 can be subjected to color correction processing.

[0060] 3. Third Embodiment Configuration Example of Imaging System FIG. 10 is a diagram showing a configuration example of an imaging system including an editing device as a third embodiment of an information processing system to which the present technology is applied.

[0061] 10, the same reference numerals are used to denote parts corresponding to those in the display system 10 in Fig. 1. Therefore, the description of those parts will be omitted as appropriate, and the following description will focus on parts that are different from the imaging system 210.

[0062] 10 is composed of a video transmission device 211, an LED controller 212, an LED display 13, an RGB camera 214, and an editing device 215. In the shooting system 210, for example, a virtual production is performed in which the video displayed on the LED display 13 is used as the background and subjects such as performers and objects are used as the foreground, and the editing device 215 performs color correction processing on the shooting data.

[0063] Specifically, the video sending device 211 acquires video data for each frame of the video to be displayed on the LED display 13 and supplies it to the LED controller 212 .

[0064] The LED controller 212 controls each display unit of the LED display 13, and displays an image corresponding to the image data supplied from the image transmission device 211 on the entire screen of the LED display 13 for each frame. The LED controller 212, like the LED controller 12, acquires the temperature data of the LED display 13 for each frame. The LED controller 212 (display control device) supplies to the editing device 215 the temperature data for each frame and a playback time code indicating the playback time of that frame, i.e., the frame of the image that was displayed on the LED display 13 when the temperature indicated by the temperature data was detected.

[0065] The RGB camera 214 (photographing device) photographs the subject in the foreground against the image displayed on the LED display 13 as the background, and generates photographic data for each frame. The RGB camera 214 records the photographic data on a recording medium or the like. At this time, the photographic data for each frame is also recorded in association with area information indicating the area of ​​the LED display 13 included in the photographing range (inner frustum). This area information is input by, for example, the photographer.

[0066] The editing device 215 (information processing system) is, for example, a device used in post-production work. The editing device 215 acquires the temperature data and playback time code for each frame supplied from the LED controller 212. The editing device 215 generates and stores a temperature file that associates the temperature data for each frame with the playback time code. The recording medium of the RGB camera 214 is inserted into the editing device 215, and the editing device 215 reads the shooting data and area information for each frame recorded on the recording medium. The editing device 215 performs color correction processing on the shooting data for each frame based on the temperature file, area information, and temperature characteristic data of the chromaticity and luminance of the LED display 13, and stores the shooting data after color correction processing.

[0067] The number of LED controllers 212 may be plural, similar to the number of LED controllers 12, and each LED controller 212 may acquire temperature data of the display unit to be controlled from the display unit. The temperature file may be generated and recorded by an information processing device provided separately from the editing device 215, and provided to the editing device 215. The shooting data may be provided to the editing device 215 via a wired or wireless transmission medium, rather than being recorded on a recording medium.

[0068] <Configuration Example of Editing Apparatus> FIG. 11 is a block diagram showing a configuration example of the editing apparatus 215 of FIG.

[0069] The editing device 215 in FIG. 11 is configured with a temperature acquisition unit 231 , a storage unit 232 , a photographic data acquisition unit 233 , a color correction processing unit 234 , and a storage control unit 235 .

[0070] The temperature acquisition unit 231 acquires the temperature data and playback time code of each frame from the LED controller 212 in Fig. 10 and generates a temperature file. The temperature acquisition unit 231 supplies the temperature file to the storage unit 232 to be stored therein.

[0071] The storage unit 232 stores temperature characteristic data of the luminance and chromaticity of the LED display 13. The storage unit 232 stores a temperature file supplied from the temperature acquisition unit 231. The storage unit 232 also stores photographed data after color correction processing supplied from the storage control unit 235.

[0072] 10 , the editing device 215 is inserted into the editing device 215. The shooting data acquisition unit 233 reads out the shooting data and area information for each frame from the recording medium 240. The shooting data acquisition unit 233 supplies the read-out shooting data and area information to the color correction processing unit 234.

[0073] The color correction processing unit 234 reads the temperature file and temperature characteristic data from the storage unit 232. For each frame, the color correction processing unit 234 extracts, from the temperature file, the temperature data of the frame for the region indicated by the region information of that frame. For each frame, the color correction processing unit 234 performs color correction processing on the background shooting data of the frame's shooting data based on the extracted temperature data and temperature characteristic data.

[0074] As a method for separating the foreground and background image data, for example, the RGB camera 214 may also capture an image in which the subject in the image data is the foreground and a monochrome image is the background. In this method, a foreground area is detected by performing chromakey processing or the like on the image data captured with the monochrome image as the background, and the foreground and background image data are separated based on that area. The foreground and background image data may also be separated by various types of image processing. The color correction processing unit 234 supplies the image data after color correction processing to the storage control unit 235.

[0075] The storage control unit 235 supplies the photographed data after color correction processing, which is supplied from the color correction processing unit 234, to the storage unit 232 for storage.

[0076] <Explanation of Temperature File Generation Process> Fig. 12 is a flowchart illustrating the temperature file generation process by the editing device 215 of Fig. 11. This temperature file generation process is started, for example, when temperature data in frame units and a playback time code are supplied from the LED controller 212 of Fig. 10.

[0077] 12, the temperature acquisition unit 231 acquires the temperature data and playback time code for each frame supplied from the LED controller 212. In step S32, the temperature acquisition unit 231 generates a temperature file that associates the temperature data for each frame acquired by the processing of step S31 with the playback time code. In step S33, the temperature acquisition unit 231 supplies the temperature file generated by the processing of step S32 to the storage unit 232 for storage. The temperature file generation processing then ends.

[0078] <Explanation of Photographed Data Processing> Fig. 13 is a flowchart for explaining photographed data processing by the editing device 215 of Fig. 11. This photographed data processing is started when the recording medium 240 is inserted into the editing device 215, for example.

[0079] 13, the shooting data acquisition unit 233 reads out the shooting data and area information for each frame from the recording media 240 and supplies them to the color correction processing unit 234. In step S52, the color correction processing unit 234 reads out the temperature file and temperature characteristic data from the storage unit 232.

[0080] In step S53, the color correction processing unit 234 performs color correction processing on the background image data of each frame based on the temperature file, the temperature characteristic data, and the region information of that frame. The color correction processing unit 234 supplies the color-corrected image data to the storage control unit 235.

[0081] In step S54, the storage control unit 235 supplies the color-corrected photographic data obtained in step S53 to the storage unit 232 for storage, and then the photographic data processing ends.

[0082] As described above, in the editing device 215, the temperature acquisition unit 231 acquires temperature data of the LED display 13, and the photographed data acquisition unit 233 acquires photographed data of the image displayed on the LED display 13. Then, the color correction processing unit 234 performs color correction processing on the photographed data based on the temperature data and temperature characteristic data. Therefore, even if the image sending device 211 or the LED controller 212 does not have a color correction function, it is possible to perform color correction processing on the image of the LED display 13 photographed by the RGB camera 214.

[0083] In the third embodiment, the area information is recorded together with the photographed data at the time of photographing, but the area information does not have to be recorded. In this case, for example, the editing device 215 performs predetermined image processing on the photographed data to detect the area of ​​the LED display 13 included in the photographed data and generate the area information.

[0084] In the third embodiment, similarly to the first embodiment, the LED controller 212 may acquire temperature data not in units of frames but in units of multiple frames or at a predetermined timing.

[0085] 4. Fourth Embodiment Configuration Example of Imaging System FIG. 14 is a diagram showing a configuration example of an imaging system including an editing device as a fourth embodiment of an information processing system to which the present technology is applied.

[0086] In the imaging system 310 of Fig. 14, parts corresponding to those in the display system 110 of Fig. 9 and the imaging system 210 of Fig. 10 are assigned the same reference numerals. Therefore, the description of those parts will be omitted as appropriate, and the description will focus on parts that differ from the display system 110 and the imaging system 210. The imaging system 310 differs from the imaging system 210 in that the temperature is detected by a thermographic camera 316 instead of an LED display 13, but is otherwise configured similarly to the imaging system 210.

[0087] Specifically, the imaging system 310 is made up of an LED controller 112 , an LED display 113 , a video sending device 211 , an RGB camera 214 , an editing device 315 , and a thermography camera 316 .

[0088] The editing device 315 (information processing system) is, for example, a device used in post-production work. A recording medium on which a temperature file is recorded by a thermographic camera 316 is inserted into the editing device 315, and the editing device 315 reads the temperature file recorded on the recording medium. The recording medium of the RGB camera 214 is also inserted into the editing device 315, and the editing device 315 reads the shooting data and area information for each frame recorded on the recording medium. The editing device 315 performs color correction processing on the shooting data for each frame based on the temperature file, area information, and temperature characteristic data of the chromaticity and brightness of the LED display 113, and stores the color-corrected shooting data.

[0089] The thermographic camera 316 (temperature detection device) captures images of the LED display 113 to detect the temperature of each pixel of the LED display 113 on a frame-by-frame basis, and generates temperature data representing that temperature. The thermographic camera 316 generates a temperature file that associates the temperature data with a capture time code that indicates the acquisition time of the captured data corresponding to that temperature data, and records the file on a recording medium, etc. The RGB camera 214 and thermographic camera 316 are synchronized, so the thermographic camera 316 can recognize the acquisition time of the captured data corresponding to the temperature data.

[0090] <Configuration Example of Editing Apparatus> FIG. 15 is a block diagram showing a configuration example of the editing apparatus 315 of FIG.

[0091] In the editing device 315 of Fig. 15, the parts corresponding to those in the editing device 215 of Fig. 11 are denoted by the same reference numerals. Therefore, the description of those parts will be omitted as appropriate, and the following description will focus on the parts that are different from the editing device 215.

[0092] The editing device 315 is composed of a shooting data acquisition unit 233 , a memory control unit 235 , a temperature acquisition unit 331 , a memory unit 332 , and a color correction processing unit 334 .

[0093] When a recording medium 340 on which a temperature file is recorded by the thermographic camera 316 in Figure 14 is inserted into the editing device 315, the temperature acquisition unit 331 reads (acquires) the temperature file from the recording medium 340 and supplies it to the color correction processing unit 334.

[0094] The storage unit 332 stores the temperature characteristic data of the luminance and chromaticity of the LED display 13 . The storage unit 332 stores the photographed data after color correction processing, which is supplied from the storage control unit 235 .

[0095] The color correction processing unit 334 reads the temperature characteristic data from the storage unit 332. For each frame, the color correction processing unit 334 extracts, from the temperature file supplied from the temperature acquisition unit 331, the temperature data of the region indicated by the region information of that frame from the temperature data of that frame. For each frame, the color correction processing unit 334 performs color correction processing on the background imaging data of the imaging data of that frame based on the extracted temperature data and temperature characteristic data, similar to the color correction processing unit 234. The color correction processing unit 334 supplies the imaging data after color correction processing to the storage control unit 235.

[0096] <Explanation of Shooting Data Processing> Fig. 16 is a flowchart illustrating shooting data processing by the editing device 315 of Fig. 15. This shooting data processing starts, for example, when the recording media 240 and 340 are inserted into the editing device 315.

[0097] 16 , the shooting data acquisition unit 233 reads the shooting data and region information for each frame from the recording medium 240 and supplies them to the color correction processing unit 334. In step S72, the temperature acquisition unit 331 reads the temperature file from the recording medium 340 and supplies it to the color correction processing unit 334. In step S73, the color correction processing unit 334 reads the temperature characteristic data from the storage unit 332.

[0098] The processing in steps S74 and S75 is the same as the processing in steps S53 and S54 in Fig. 13, and therefore a description thereof will be omitted. After the processing in step S75, the photographic data processing ends.

[0099] As described above, the editing device 315 performs color correction processing on the captured image data of the image displayed on the LED display 113, based on the temperature file and temperature characteristic data generated by the thermographic camera 316. Therefore, even if the LED controller 112 and the image transmission device 211 do not have a color correction function and the LED display 113 does not have a temperature sensor, the editing device 315 can perform color correction processing on the captured image of the LED display 113.

[0100] In the first to fourth embodiments, the color correction process is performed for each frame, but the color correction process can also be performed only for a predetermined frame.

[0104] Specifically, like the LED controller 12, the LED controller 412 acquires temperature data of the LED display 13 for each frame from the LED display 13 and supplies the data to the information processing device 414. The LED controller 412 acquires color correction data transmitted from the information processing device 414 in accordance with the temperature data for each frame. The LED controller 412 performs color correction processing on the video data supplied from the video transmission device 211 for each frame using the color correction data. The LED controller 412 controls each display unit of the LED display 13 to display an image corresponding to the video data after color correction processing on the entire screen of the LED display 13 for each frame.

[0105] The information processing device 414 is configured by, for example, a personal computer. The information processing device 414 generates color correction data for each frame based on the temperature data supplied from the LED controller 412 and the temperature characteristic data of the LED display 13. This color correction data is configured by, for example, correction values ​​for the luminance and chromaticity of each pixel of the LED display 13. The information processing device 414 transmits the color correction data for each frame to the LED controller 412.

[0106] The number of LED controllers 412 may be plural, similar to the number of LED controllers 12 .

[0107] <Description of Color Correction Data Generation Processing> Fig. 18 is a flowchart illustrating the color correction data generation processing by the information processing device 414 in Fig. 17. This color correction data generation processing is performed, for example, for each frame of the video to be displayed on the LED display 13.

[0108] 18 , the information processing device 414 acquires temperature data supplied from the LED controller 412. In step S112, the information processing device 414 generates color correction data based on the temperature data acquired in step S111 and the temperature characteristic data of the LED display 13. In step S113, the information processing device 414 transmits the color correction data generated in step S112 to the LED controller 412. Then, the color correction data generation process ends.

[0109] <Explanation of Display Control Processing> Fig. 19 is a flowchart illustrating the display control processing by the LED controller 412 of Fig. 17. This display control processing is performed, for example, in units of frames of the video to be displayed on the LED display 13.

[0110] 19, the LED controller 412 acquires the video data supplied from the video transmission device 211. In step S132, the LED controller 412 acquires the color correction data transmitted from the information processing device 414 by the processing of step S113 in FIG.

[0111] In step S133, the LED controller 412 performs color correction processing on the video data acquired in the processing of step S131 using the color correction data acquired in the processing of step S132. In step S134, the LED controller 412 controls each display unit of the LED display 13 to display an image corresponding to the video data after the color correction processing on the entire screen of the LED display 13. Then, the display control processing ends.

[0112] As described above, the information processing device 414 generates color correction data based on the temperature data and temperature characteristic data, and transmits it to the LED controller 412. Therefore, the LED controller 412 can easily perform color correction processing on the video data using this color correction data.

[0113] 6. Display System that Generates Color Correction Data Based on Temperature Detected by Thermography Camera Configuration Example of Display System FIG. 20 is a block diagram showing a configuration example of a display system that generates color correction data based on temperature detected by a thermography camera.

[0114] In the display system 510 of Fig. 20, parts corresponding to the display system 110 of Fig. 9 and the display system 410 of Fig. 17 are assigned the same reference numerals. Therefore, the description of those parts will be omitted as appropriate, and the description will focus on parts that are different from the display systems 110 and 410. The display system 510 differs from the display system 410 in that the temperature is detected by a thermographic camera 114 instead of an LED display 13, but is otherwise configured similarly to the display system 410.

[0115] Specifically, the display system 510 is composed of an LED display 113 , a thermography camera 114 , a video transmission device 211 , an LED controller 512 , and an information processing device 514 .

[0116] The LED controller 512 differs from the LED controller 412 in that it does not acquire temperature data from the LED display 113, but is otherwise configured in the same manner as the LED controller 12. The number of LED controllers 512 may be plural, similar to the number of LED controllers 12.
