<First Embodiment>
[Outline of display device 1]
FIG. 1 is a diagram for explaining an overview of the display device 1 according to the first embodiment. The display device 1 can receive a plurality of video signals from one or more photographing devices 5 and simultaneously display a plurality of image data based on the inputted video signals. In FIG. 1A, image data 61 output from the image capturing device 5a and image data 62 output from the image capturing device 5b are input to the display device 1, and the display device 1 displays the image data 61 and the image data 62. FIG. FIG. 1B is a diagram illustrating a state in which image data 61 and image data 63 output from the imaging device 5a are input to the display device 1, and the display device 1 displays the image data 61 and the image data 63. . The imaging device 5a and the imaging device 5b are image output devices that output captured images.

  The display device 1 includes an image obtained by performing predetermined image processing on at least one of a plurality of image data based on a plurality of video signals, and information related to the photographing device 5 that has output the image data (hereinafter referred to as output device information). ) Can be displayed on at least one of the plurality of image data. The output device information is information relating to a photographing device that outputs a video signal input to the display device 1 and a photographing environment.

  The display device 1 determines whether or not the plurality of image data is image data output from the same imaging device 5. If the plurality of image data is not output from the same imaging device 5, the display device 1 The image data is displayed in a state where predetermined image processing is performed. On the other hand, when a plurality of image data output from the same photographing device 5 is input, the display device 1 performs predetermined image processing on at least one image data and applies the other image data to the other image data. A plurality of image data is displayed in a state where predetermined image processing is not performed.

  In FIG. 1A, it is assumed that the display device 1 displays the image data 61 and the image data 62 output from the imaging device 5a and the imaging device 5b. In this case, the same image processing is performed on the image data 61 and the image data 62, and the output device information of the corresponding photographing device 5a and photographing device 5b is displayed on both the image data 61 and the image data 62. By doing in this way, it becomes easy for a user to compare in the state which performed the same image process to the different image data 61 and the image data 62 output from the different imaging devices 5. FIG.

  On the other hand, in FIG.1 (b), it is assumed that the display apparatus 1 displays the image data 61 and the image data 63 output from the one imaging device 5a. For example, when the photographing apparatus 5 can output the RAW image data as the image data 62 and the monitor image data as the image data 63, the photographer displays the RAW image data in a state where the monitor image data is displayed in monochrome. There is a case where it is desired to make a color display for comparison.

  In such a case, as shown in FIG. 1B, the display device 1 performs image processing on the image data 61 but does not perform image processing on the image data 63. The display device 1 superimposes output device information on the image data 61 but does not superimpose output device information on the image data 63. For example, as shown in FIG. 1B, the display device 1 arranges and displays the output device information at a position corresponding to the image data 61, but displays the output device information at a position corresponding to the image data 63. Do not arrange and do not display output device information. In this way, for example, the user can display only a part of the color of the image data 61 and display it in comparison with the image data 63, thereby affecting the appearance of the image. It becomes possible to confirm.

The display device 1 controls which image data among a plurality of image data is subjected to image processing based on the output device information. Since the display device 1 has such a configuration, the photographer can perform comparison by performing different image processing on the image data output from the same photographing device without manually performing a setting operation. .
Hereinafter, the configuration and operation of the display device 1 will be described in detail.

[Configuration of Display Device 1]
FIG. 2 is a diagram illustrating a configuration of the display device 1 according to the first embodiment. The display device 1 includes an image acquisition unit 11, a display control unit 12, and a display unit 13. The display unit 13 is a display that displays display image data output from the display control unit 12.

  The image acquisition unit 11 includes a first image acquisition unit 111 and a second image acquisition unit 112. The first image acquisition unit 111 and the second image acquisition unit 112 include, for example, an SDI input terminal that conforms to the SDI (Serial Digital Interface) standard, and receives first image data from the imaging device 5 outside the display device 1. A second video signal including the first video signal including the second image data is acquired. The first image acquisition unit 111 and the second image acquisition unit 112 extract first image data and second image data in a format that can be processed inside the display device 1 from the acquired first video signal and second video signal. Then, the first image data and the second image data are output to the display control unit 12.

  The display control unit 12 includes an image synthesis unit 121, an image processing unit 122, a screen synthesis unit 123, a display image output unit 124, a meta information analysis unit 125, an identity determination unit 126, a setting information holding unit 127, and a camera information screen generation unit. 128. The display control unit 12 generates display image data to be displayed on the display unit 13 based on the first image data and the second image data input from the image acquisition unit 11, and displays the display image data on the display unit 13. Display.

  Specifically, the display control unit 12 operates as follows. First, the display control unit 12 determines whether the plurality of image data is image data output from the same photographing device 5 based on the meta information associated with the plurality of image data acquired by the image acquisition unit 11. To do. For example, the display control unit 12 indicates that the meta information associated with the plurality of image data acquired by the image acquisition unit 11 indicates that the plurality of image data is image data output from the same imaging device 5. Determine. The display control unit 12 performs predetermined image processing on at least one of the plurality of image data and outputs at least one other image data when a plurality of image data is output from the same photographing device 5. A plurality of pieces of image data are displayed on the display unit 13 without performing predetermined image processing on the data.

  In addition, when the display control unit 12 determines that the plurality of image data is not image data output from the same photographing device 5 based on the meta information, a predetermined image is added to all the image data of the plurality of image data. The image is displayed on the display unit 13 with processing or without performing predetermined image processing on all image data. For example, when the meta information indicates that the plurality of pieces of image data are not image data output from the same photographing device 5, the display control unit 12 adds a predetermined image to all the pieces of image data of the plurality of pieces of image data. The image is displayed on the display unit 13 with processing or without performing predetermined image processing on all image data.

  The display control unit 12 displays the first image data in the first region of the display unit 13 and displays the second image data in the second region of the display unit 13. Therefore, when the meta information indicates that the plurality of pieces of image data are image data output from the same photographing device 5, the display control unit 12 may select a part of the plurality of regions of the display unit 13. Predetermined image processing is performed on the first image data displayed in the area (for example, the first area), and the display control unit 12 performs predetermined processing on the second image data displayed in at least some other areas (for example, the second area). The image processing is not performed. When the meta information indicates that the plurality of pieces of image data are not image data output from the same photographing device 5, the display control unit 12 adds a predetermined image to the image data to be displayed in the entire area of the display unit 13. The image is displayed on the display unit 13 with processing or without performing predetermined image processing on all image data.

  The display control unit 12 also displays a plurality of pieces of image data when the meta information associated with the plurality of pieces of image data indicates that the pieces of image data are image data output from the same photographing device 5. Output device information is superimposed on at least one image data (for example, first image data), and a plurality of image data is not superimposed on output device information on at least one other image data (for example, second image data). It may be displayed on the display unit 13. For example, the display control unit 12 arranges and displays the output device information at the position corresponding to the first image data, and does not arrange the output device information at the position corresponding to the second image data. Is not displayed. When the meta information indicates that the plurality of image data is not the image data output from the same photographing device 5, the display control unit 12 outputs the image information to positions corresponding to all the image data of the plurality of image data. Arrange and display device information. By doing in this way, it can prevent that the same information is displayed on the several location of the display part 13, and it becomes difficult to see an image.

  Further, the display control unit 12 may further use video signal format information as meta information. Specifically, the display control unit 12 determines whether the plurality of image data are the same based on the video signal format of the plurality of image data. The display control unit 12 performs predetermined image processing on at least one of the plurality of image data and performs predetermined image processing on at least one other image data when the plurality of image data are the same. Without the application, a plurality of image data is displayed on the display unit 13.

The display control unit 12 superimposes the output device information on at least one of the plurality of image data when the video signal format information indicates that the plurality of image data is the same, and A plurality of image data is displayed on the display unit 13 without superimposing output device information on at least one other image data. For example, the display control unit 12 arranges and displays the output device information at a position corresponding to at least one image data among the plurality of image data, and outputs the output device information at a position corresponding to at least one other image data. Is not arranged, and output device information is not displayed. When the video signal format information indicates that the plurality of image data are not the same, the display control unit 12 displays the output device information superimposed on all the image data of the plurality of image data. For example, the display control unit 12 arranges and displays the output device information at positions corresponding to all image data.
Details of the operation of each unit of the display control unit 12 will be described below.

  The image composition unit 121 synthesizes the first image data and the second image data input from the first image acquisition unit 111 and the second image acquisition unit 112 based on the display mode set by the user. Here, the display mode is a mode related to a mode of displaying the first image data and the second image data. The display device 1 simultaneously displays the “first image display mode” for displaying only the first image data, the “second image display mode” for displaying only the second image data, and the first image data and the second image data. The “multi-display mode” has three display modes, and the user can select a desired display mode.

  When the display mode is the “first image display mode”, the image composition unit 121 outputs only the first image data to the image processing unit 122. When the display mode is the “second image display mode”, the image composition unit 121 outputs only the second image data to the image processing unit 122. When the display mode is “multi-display mode”, the image composition unit 121 combines the composite image data obtained by combining the first image data and the second image data so as to be arranged in the left and right areas of the display unit 13. Output to.

  The image processing unit 122 performs image processing indicated by the image quality setting information acquired from the setting information holding unit 127 on the image data input from the image combining unit 121, and the image data after the image processing is displayed on the screen combining unit 123. Output to. Here, the image quality setting information is information indicating the contents of image processing, and is held in the setting information holding unit 127 in a table format, for example.

FIG. 3 is a table showing an example of image quality setting information.
“Image quality setting target” is a setting referred to when the display mode is “multi-display mode”, and image processing is performed on any image data or area of “all images”, “left image”, and “right image”. Is information indicating whether or not to apply. FIG. 3 shows a state where “all images” for displaying both the first image data and the second image data is set.

“Peaking” is a function for highlighting (coloring) an area corresponding to the contour portion of an image. If “ON”, this function is applied, and if “OFF”, this function is not applied.
“False color” is a function of coloring with a different color for each luminance level of the video. If “ON”, this function is applied, and if “OFF”, this function is not applied.
“Monochrome” is a function for displaying an image in monochrome. This function is applied if it is “ON”, and this function is not applied if it is “OFF”.
“Blue Only” is a function that removes the red and green components of the image and displays only the blue component in monochrome. This function is applied if it is “ON”, and this function is applied if it is “OFF”. Not.

The screen composition unit 123 generates composite image data by superimposing the camera information screen data including the camera information as the output device information input from the camera information screen generation unit 128 on the image data input from the image processing unit 122. Then, the generated composite image data is output to the display image output unit 124. The screen composition unit 123 generates composite image data including, for example, the image data input from the image processing unit 122 and camera information screen data arranged in the vicinity of the image data.
The display image output unit 124 outputs the composite image data input from the screen composition unit 123 to the display unit 13.

  The meta information analysis unit 125 extracts meta information such as video signal format information and output device information included in the first image data and the second image data input from the first image acquisition unit 111 and the second image acquisition unit 112. To do. The meta information analysis unit 125 outputs the extracted meta information to the identity determination unit 126. Further, the meta information analysis unit 125 outputs the output device information to the camera information screen generation unit 128.

  The video signal format information is information relating to the format of the video signal output from the photographing apparatus. FIG. 4 is a diagram illustrating an example of video signal format information. As shown in FIG. 4, the video signal format information includes information on resolution, frame rate, I / P conversion type, color format, and color depth. For example, the video signal format information is stored in the payload data area of the SDI signal.

  FIG. 5 is a diagram illustrating an example of output device information. As shown in the table of FIG. 5, the output device information includes information such as model name, serial number, shooting date / time, aperture value, shutter speed, ISO sensitivity, and focal length. The output device information is stored, for example, in the ancillary data area of the SDI signal.

  The identity determination unit 126 is based on the output device information associated with the plurality of image data input from the meta information analysis unit 125, whether the plurality of image data is image data output from the same imaging device 5. Determine whether or not. Specifically, the identity determination unit 126 compares the output device information associated with the first image data with the output device information associated with the second image data, and the comparison results match. In addition, it is determined that the plurality of image data are image data output from the same photographing device 5. For example, the identity determination unit 126 outputs a plurality of image data from the same imaging device 5 based on whether or not the model name and imaging conditions of the imaging device 5 associated with the plurality of image data are the same. It is determined whether or not the image data. The identity determination unit 126 outputs the determination result to the setting information holding unit 127 and the camera information screen generation unit 128.

  The setting information holding unit 127 stores setting information for specifying image data or a display area to be subjected to predetermined image processing on the image data. The setting information holding unit 127 holds, for example, information of “all images”, “right image”, or “left image” as setting information indicating image data to be subjected to image processing. The setting information holding unit 127 may hold information of “all area”, “right area”, or “left area” as setting information indicating image data to be subjected to image processing.

  The setting information holding unit 127 determines that the identity determination unit 126 determines that a plurality of pieces of image data are image data output from the same imaging device 5, and that the setting information includes all targets to be subjected to predetermined image processing. When the image data or the entire area of the display unit 13 is indicated, a part of the plurality of pieces of image data (for example, “right image”) or the display unit is subjected to predetermined image processing. The area is changed to a partial area 13 (for example, “right area”).

  The setting information holding unit 127 may further hold setting information for specifying an area or image data in which the information of the device that output the image data is superimposed and displayed. In this case, the setting information holding unit 127 determines that the identity determination unit 126 is the image data output from the same photographing apparatus 5 and the setting information performs predetermined image processing. When the target image data indicates the entire image data or the entire area of the display unit 13, the image data for superimposing the output device information is changed to a part of the image data or a part of the display area. .

  The setting information holding unit 127 outputs setting information to the image processing unit 122 in response to a request from the image processing unit 122. In addition, the setting information holding unit 127 updates the setting information output to the image processing unit 122 according to the determination result of whether or not the image data is output from the same imaging device 5 input from the identity determination unit 126. To do. Details of the operation when the setting information holding unit 127 updates the setting information will be described later.

  The camera information screen generation unit 128 generates a camera information screen with reference to the meta information of the first image data and the second image data input from the meta information analysis unit 125, and outputs the camera information screen to the screen synthesis unit 123. To do. For example, the camera information screen generation unit 128 generates a camera information screen including the output device information illustrated in FIG. Further, the camera information screen generation unit 128 determines whether to display the camera information screen according to the determination result input from the identity determination unit 126. When the determination result input from the identity determination unit 126 indicates that the first image data and the second image data are output from the same imaging device 5, the camera information screen generation unit 128 The camera information screen is generated so that the output device information is superimposed on the image data and the output device information is not superimposed on the other image data. Details of the operation of the camera information screen generation unit 128 will be described later.

[Processing flow of display device 1]
FIG. 6 is a flowchart showing a processing flow of the display device 1.
First, the first image acquisition unit 111 and the second image acquisition unit 112 acquire image data and meta information included in the video signal output from the imaging device 5 (S101).

  Subsequently, the image composition unit 121 synthesizes the first image data and the second image data according to the display mode (S102). If the display mode is “first image display mode”, the image composition unit 121 generates composite image data in which the first image data is arranged at the center of the screen. If the display mode is “second image display mode”, the image composition unit 121 generates composite image data in which the second image data is arranged at the center of the screen. If the display mode is “multi-display mode”, the image composition unit 121 generates composite image data in which the first image data is arranged on the left side of the screen and the second image data is arranged on the right side of the screen.

  Subsequently, the image processing unit 122 applies image processing to the combined image data generated by the image combining unit 121 based on the image quality setting information acquired from the setting information holding unit 127 (S103). When the display mode is “multi-display mode”, the image processing unit 122 determines an image processing application area based on “image quality setting target” of the image quality setting information. If the “image quality setting target” is “all images”, the image processing unit 122 applies predetermined image processing to a plurality of image data. If the “image quality setting target” is “left image”, the image processing unit 122 applies image processing only to the first image data displayed in the left area of the screen. If the “image quality setting target” is “right image”, the image processing unit 122 applies image processing only to the second image data displayed in the right area of the screen.

  Subsequently, the screen composition unit 123 generates display image data by superimposing the camera information screen input from the camera information screen generation unit 128 on the composite image data after image processing (S104). The display image output unit 124 outputs the display image data generated by the screen composition unit 123 to the display unit 13 (S105). The display unit 13 displays the display image data input from the display image output unit 124 (S106).

[Display screen example]
FIG. 7 is a diagram illustrating an example of a screen displayed in each display mode. FIG. 7 shows an example in which the first image data and the second image data are input from different photographing devices 5, respectively.

  FIG. 7A shows an example of a screen when the display mode is “first image display mode”. In this case, the area to which the image processing unit 122 applies image processing is the entire screen, and only information corresponding to the first image data is displayed on the camera information screen.

  FIG. 7B is a screen example when the display mode is the “second image display mode”. In this case, the area to which the image processing unit 122 applies image processing is the entire screen, and only information corresponding to the second image data is displayed on the camera information screen.

  FIG. 7C shows an example of a screen when the display mode is “multi-display mode”. In this case, the area to which the image processing unit 122 applies the image processing is determined according to “image quality setting target” of the image quality setting information, and each information of the first image data and the second image data is displayed on the camera information screen. Is displayed.

[Flow of processing when displaying the same image]
FIG. 8 is a flowchart showing the flow of processing when displaying the same image. The process flowchart of FIG. 8 starts from the process in which the image acquisition unit 11 acquires the first image data and the second image data (S201). When the image acquisition unit 11 acquires the first image data and the second image data, the identity determination unit 126 determines whether the first image data and the second image data are output from the same imaging device 5 (S202). ).

  The setting information holding unit 127 refers to the determination result by the identity determination unit 126, and in the case of the determination result that the image is output from the same photographing device 5, the “image quality setting target” of the image quality setting information is “all images”. Is determined (S203). When the “image quality setting target” is “all images”, the setting information holding unit 127 changes the “image quality setting target” to “left image” (S204). The setting information holding unit 127 ends the process without changing the “image quality setting target” when the “image quality setting target” is set to “left image” or “right image” instead of “all images”. To do.

  As described above, when a plurality of image data is output from the same photographing device 5 and “image quality setting target” is set to “all images”, the “image quality setting target” is automatically changed. The display device 1 can perform image processing only on one of the first image data and the second image data without the user manually switching the setting. Note that the display device 1 of the present embodiment superimposes the output device information on the image data set in the “image quality setting target”, but the display device 1 is the target of superimposing the output device information. Other setting information for designating image data may be stored.

[Processing Flow of Camera Information Screen Generation Unit 128]
FIG. 9 is a flowchart showing a process flow of the camera information screen generation unit 128. In the flowchart illustrated in FIG. 9, the process is started when the display mode is changed, when the determination result in the identity determination unit 126 is changed, or when the meta information is changed.

  The camera information screen generation unit 128 refers to the current display mode, and if it is the “multi-display mode”, the process proceeds to step S302, and the first image data and the second image data are output from the same photographing device 5. Determine whether it was done. If it is “first image display mode”, the camera information screen generation unit 128 proceeds to step S304, and if it is “second image display mode”, the process proceeds to step S305 (S301).

  When the display mode is “multi-display mode”, the camera information screen generation unit 128 refers to the determination result in the identity determination unit 126. When the determination result indicates that the first image data and the second image data are not output from the same photographing device 5 (NO in S302), the camera information screen generation unit 128 determines the first image data and the second image data. Camera information corresponding to each image data is extracted from the meta information of the second image data. The camera information screen generation unit 128 arranges the first camera information corresponding to the first image data in the left area of the display unit 13, and displays the second camera information corresponding to the second image data in the right area of the display unit 13. The camera information screen arranged in (1) is generated (S303).

  When the determination result referred to in step S302 indicates that the first image data and the second image data are output from the same photographing device 5 (YES in S302), the camera information screen generation unit 128 is the same. In order to prevent a plurality of camera information screens from being displayed, a camera information screen is generated only for the first image data (S304). Specifically, the camera information screen generation unit 128 extracts camera information corresponding to the first image data from the meta information of the first image data, and generates a camera information screen including the extracted camera information.

  When it is determined in step S301 that the second image display mode is set, the camera information screen generation unit 128 extracts camera information corresponding to the second image data from the meta information of the second image data. The camera information screen generation unit 128 generates a camera information screen including the extracted camera information (S305).

[Display example of the same image]
Next, an image processing application result and a display screen example when the first image data and the second image data are the same will be described with reference to FIGS. 10 and 11. FIG. 10 is a diagram illustrating a setting state of image quality setting information. FIG. 11 is a diagram illustrating an example of a display screen.

  FIG. 10A shows an example of image quality setting information when the display mode is set to “first image display mode”, and FIG. 11A shows an example of the display screen in this case. Yes. In the image quality setting information shown in FIG. 10A, the image quality setting target is set to “all images”, the false color is set to “ON”, and the other items are set to “OFF”. FIG. 11A shows an example of a display screen when the image quality setting information is in the state shown in FIG. Since the display mode is the “first image display mode”, in FIG. 11A, image processing for conversion to false color is applied to the entire area, and camera information corresponding to the first image data to be displayed is displayed. Has been.

  FIG. 10B shows an example of image quality setting information when the display mode is switched from the “first image display mode” to the “multi-display mode”, and FIG. 11B shows the display in this case. An example screen is shown. When the determination result in the identity determination unit 126 indicates that the first image data and the second image data are output from the same photographing device 5, in step S203 of the flowchart shown in FIG. Since the image quality setting target of the setting information is changed from “all images” to “left image”, the image quality setting information is changed as shown in FIG. Then, the image processing with the false color “ON” setting is applied only to the first image data displayed in the left region, and the second image data to which no image processing is applied is displayed in the right region.

  Further, the display mode is the “multi-display mode”, and the determination result in the identity determination unit 126 indicates that the first image data and the second image data are output from the same imaging device 5. In this case, only the camera information corresponding to the first image data is displayed as shown in step S304 of the flowchart of FIG. As a result, as shown in FIG. 11B, when the display mode is the “multi-display mode” and the first image data and the second image data are output from the same photographing device 5, the image processing is performed. Applies only to the left area, and camera information is displayed only in the left area.

[Effects of the display device 1 according to the first embodiment]
As described above, the display device 1 according to the first embodiment determines whether image data corresponding to a plurality of input video signals is output from the same imaging device 5, and the same imaging device 5. When the image data is output from the image data, only one of the image data is subjected to image processing and displayed. The display device 1 displays only camera information corresponding to one image data. By doing in this way, when a plurality of image data is output from the same photographing device 5, the display device 1 is in a state where image processing is performed and image processing is not performed. Since the image data can be displayed, the user can compare a plurality of images without performing a setting operation regarding which image data is subjected to image processing. As a result, it is possible to eliminate the trouble of the user manually setting the image quality setting target and the troublesomeness caused by displaying the same camera information at the same time, and the user's work can be made efficient.

(Modification)
In the above description, the image quality setting information is a table as shown in FIG. 3, but more detailed image quality setting items may be included.
Further, in the above description, the signal format information used for determining whether or not the identity determination unit 126 is the same image is a table as shown in FIG. 4, but the signal format information is more detailed. Format information may be included.

In the above description, the output device information used by the identity determination unit 126 to determine whether or not a plurality of image data is output from the same imaging device 5 is a table as shown in FIG. The output device information may include more detailed information.
In the above description, the identity determination unit 126 determines whether or not the images are the same based on the result of comparison of all items of the meta information. Only some of the information may be used.

  In the above description, the case where the display device 1 acquires two image data and displays the two image data simultaneously has been described. However, the display device 1 may display more image data. For example, the display device 1 may display four image data in the four areas of the upper left, upper right, lower left, and lower right. In this case, when at least two of the four image data are output from the same photographing device 5, the display device 1 performs predetermined image processing on one of the two image data, The other is not subjected to predetermined image processing. Further, output device information is superimposed on one of these two image data, and output device information is not superimposed on the other.

<Second Embodiment>
The display device 2 according to the second embodiment is different from the display device 1 according to the first embodiment in that it has a through-out function that outputs an input video signal as it is.
FIG. 12 is a diagram illustrating a configuration of the display device 2 according to the second embodiment. Hereinafter, differences from the display device 1 according to the first embodiment will be described.

  The display device 2 includes an image output unit 14 in addition to the image acquisition unit 11, the display control unit 12, and the display unit 13 that are the same as those of the display device 1. The image output unit 14 includes an information adding unit 141, a first image output unit 142, and a second image output unit 143. The image output unit 14 adds display device information associated with the display device 1 to at least one of the plurality of image data acquired by the image acquisition unit 11 and outputs the image data. Details of the display device information will be described later.

  The first image acquisition unit 111 outputs the acquired first image data to the information addition unit 141 together with the image synthesis unit 121 and the meta information analysis unit 125. Similarly, the second image acquisition unit 112 outputs the acquired second image data to the information addition unit 141 together with the image synthesis unit 121 and the meta information analysis unit 125.

  The information adding unit 141 adds through-out information as display device information to the input first image data and second image data, and outputs them to the first image output unit 142 and the second image output unit 143. For example, the information adding unit 141 adds through-out information to an unused area of the ancillary data area of the SDI signal. The through-out information includes information for specifying the display device 2 and which image acquisition interface among a plurality of image acquisition interfaces (for example, the first image acquisition unit 111 and the second image acquisition unit 112) included in the image acquisition unit 11. And input unit information for specifying whether image data has been acquired from.

  FIG. 13 is a table showing an example of the through-out information. As shown in FIG. 13, the through-out information includes a model name, a serial number, and input unit information. In the model name, the model name of the display device 2 that outputs image data through-out is stored. The serial number stores the serial number of the display device 2 that outputs the image data through-out. The input unit information stores information indicating which of the first image acquisition unit 111 and the second image acquisition unit 112 outputs the acquired image data. In this embodiment, “1” is output when the image data acquired by the first image acquisition unit 111 is output, and “2” is output when the image data acquired by the second image acquisition unit 112 is output. Stored in

  The first image output unit 142 and the second image output unit 143 output a video signal including the first image data and the second image data to which the through-out information is added by the information adding unit 141 to an external device. In the present embodiment, the first image output unit 142 outputs a video signal including the first image data acquired by the first image acquisition unit 111, and the output video signal is the first of the display device 2 as an external device. It is assumed that the two-image acquisition unit 112 is input.

  In the display control unit 12, the through-out information included in the meta information associated with the first image data acquired by the first image acquisition unit 111 includes input unit information corresponding to the second image acquisition unit 112. If there is a plurality of pieces of image data, the plurality of pieces of image data are determined to be image data output from the same photographing device 5. The process in which the display control unit 12 determines image data or a region to be subjected to image processing based on the determination result is the same as that in the first embodiment. Similarly to the first embodiment, the display control unit 12 may determine image data or a region that is a target for displaying output device information based on the determination result.

  FIG. 14 is a flowchart of a process in which the identity determination unit 126 according to the second embodiment determines the identity of the imaging device 5 that has output a plurality of image data. The flowchart in FIG. 14 starts when meta information is input to the identity determination unit 126.

  When the meta information is input, the identity determination unit 126 determines whether the meta information includes through-out information (S401). If the identity determination unit 126 determines that the meta information includes the through-out information, the process proceeds to step S402. If the identity determination unit 126 determines that the meta-information does not include the through-out information, the process proceeds to step S404.

  In step S402, the identity determination unit 126 determines whether the model name and serial number indicated by the through-out information are the same as the model name and serial number of the display device 2. If it is determined that the model name and serial number indicated by the through-out information match the model name and serial number of the display device 2, the identity determination unit 126 proceeds to step S403, and if not, proceeds to S404 (S402). ).

  In step S403, the identity determination unit 126 determines whether the input unit information indicated by the through-out information corresponds to the first image acquisition unit 111 different from the second image acquisition unit 112 that acquired the image data including the through-out information. Determine whether. That is, the identity determination unit 126 determines whether the second image data to be displayed in the left area is the same as the first image data to be displayed in the right area. For example, when the input part information indicated by the through-out information included in the second image data acquired by the second image acquisition unit 112 is “1”, the identity determination unit 126 determines that the second image data is the first image. It is determined that the image data is the same as the first image data input to the acquisition unit 111.

  The identity determination unit 126 is configured such that the input unit information indicated by the through-out information of the image data acquired by either the first image acquisition unit 111 or the second image acquisition unit 112 corresponds to the other image acquisition unit. Then, it is determined that the image data acquired by the other image acquisition unit has been output through, and the process proceeds to step S406. When the identity determination unit 126 does not correspond to the other image acquisition unit, the input unit information indicated by the through-out information of the image data acquired by either the first image acquisition unit 111 or the second image acquisition unit 112 The process proceeds to step S404.

  In step S404, the identity determination unit 126 performs signal format information and output device information corresponding to the first image data, and signal format information corresponding to the second image data, as in the display device 1 of the first embodiment. And the output device information are compared. The identity determination unit 126 proceeds to step S406 if the comparison results match, and proceeds to S407 if they do not match (S405).

  In step S406, the identity determination unit 126 determines that the first image data and the second image data are output from the same imaging device 5. In step S407, the identity determination unit 126 determines that the first image data and the second image data are not output from the same imaging device 5. The identity determination unit 126 outputs the determination results in steps S406 and S407 to the setting information holding unit 127 and the camera information screen generation unit 128.

[Effects of the display device 2 of the second embodiment]
As described above, the display device 2 outputs the video signal corresponding to the first image data acquired by the first image acquisition unit 111 as a through-out output. In the use case where the display device 2 uses the through-out information added to the video signal that has been output through, the video signal that has been output through is input to the second image acquisition unit 112, the signal format information and the output It is possible to easily determine whether or not a plurality of image data input to the image acquisition unit 11 is output from the same photographing device 5 without referring to the device information. Since the display device 2 does not need to refer to the signal format information and the output device information, even if a video signal that does not include the signal format information and the output device information is input as meta information, a plurality of image data are stored. It can be determined whether or not the images are output from the same photographing device 5.

<Third Embodiment>
The display device 3 according to the third embodiment is different from the display device 1 according to the first embodiment and the display device 2 according to the second embodiment in that it has a function of replicating an input video signal. Since the display device 3 generates the left image and the right image by duplicating the video signal, the left image and the right image are the same depending on whether the image quality mode for the left screen and the image quality mode for the right screen are the same. It is determined whether or not there is.

FIG. 15 is a diagram illustrating a configuration of the display device 3 according to the third embodiment. Hereinafter, differences from the display device 1 according to the first embodiment will be described.
Similar to the display device 1, the display device 3 includes an image acquisition unit 11, a display control unit 12, and a display unit 13. The display control unit 12 of the display device 3 is different from the display control unit 12 of the display device 1 in that the display control unit 12 includes an image duplication unit 129 and does not include the meta information analysis unit 125 and the identity determination unit 126.

  The image acquisition unit 11 is different from the display device 1 in that the image acquisition unit 11 includes the first image acquisition unit 111 but does not include the second image acquisition unit 112. The first image acquisition unit 111 outputs the acquired first image data to the image duplication unit 129 together with the image synthesis unit 121 and the meta information analysis unit 125. Since the image acquisition unit 11 includes only the first image acquisition unit 111, the camera information displayed by the display device 3 is always one regardless of the display mode.

  When the display control unit 12 determines that the display mode is set to display a plurality of image data including the first image data and the second image data generated by duplicating the first image data, Predetermined image processing is performed on at least one of the image data. In this case, the display control unit 12 displays a plurality of image data on the display unit 13 without performing predetermined image processing on at least one other image data.

  The setting information holding unit 127 of the display device 3 holds the image quality mode for the left screen and the image quality mode for the right screen separately from the image quality setting information described in the first embodiment. The image quality mode is an image quality mode in which an image is determined by a predetermined color gamut, gradation conversion gamma, or the like. The display device 3 can display an image having a user-desired image quality by applying a LUT (lookup table) registered in advance to the input image signal. The image quality mode includes, for example, “ITU-R BT.709”, “ITU-R BT.2020”, and “AdobeRGB”, and the setting information holding unit 127 sets the image quality for the left screen set by the user. Holds the mode and the image quality mode for the right screen.

  First, the image processing unit 122 acquires the image quality mode for the left screen and the image quality mode for the right screen from the setting information holding unit 127. The image processing unit 122 applies an LUT corresponding to each of the image quality mode for the left screen and the image quality mode for the right screen to the input image, so that an image in a desired image quality mode is displayed on each of the left screen and the right screen. Execute the process. Thereafter, the image processing unit 122 executes image quality setting processing according to the image quality setting information acquired from the setting information holding unit 127, similarly to the processing described in the first embodiment.

  When the image duplicating unit 129 determines that the display mode set by the user is the duplicating multi-display mode, the image duplicating unit 129 generates second image data obtained by duplicating the first image data input from the first image obtaining unit 111. Here, the duplicate multi-display mode is a multi-display mode in which the second image data is duplicated from the first image data and the first image data and the second image data are displayed simultaneously. Note that the display device 3 may simultaneously display a total of three or more pieces of image data by duplicating two or more pieces of image data from the first image data in the image duplicating unit 129.

  The display device 3 displays only the first image data without performing the duplication as described in the first and second embodiments, together with the “duplicate multi-display mode” in which duplication is performed. "Image display mode". The user can select a desired display mode from these display modes. As described in the first embodiment and the second embodiment, the display device 3 simultaneously displays the first image data acquired from the outside and the second image data acquired from the outside “multi-display mode”. May be further included.

  When the image duplicating unit 129 determines that the set display mode is the duplicating multi-display mode, the image duplicating unit 129 acquires the image quality mode for the left screen, the image quality mode for the right screen, and the image quality setting information from the setting information holding unit 127. . When the image quality mode for the left screen is different from the image quality mode for the right screen, or when any item other than “image quality setting target” in the image quality setting information is “ON”, the image duplicating unit 129 performs the first operation. The image data is duplicated to generate second image data, and the generated second image data is output to the image composition unit 121. In other cases, the image duplicating unit 129 ends the process without duplicating the first image data. When the image quality mode or the image quality setting information is updated, the image duplicating unit 129 again determines whether or not to duplicate.

  FIG. 16 is a flowchart showing the flow of processing when displaying the same image. The flowchart of FIG. 16 starts from the process in which the image acquisition unit 11 acquires the first image data (S501). When the image acquisition unit 11 acquires the first image data, the image duplication unit 129 determines whether to duplicate the first image data based on the current display mode and the image quality setting information acquired from the setting information holding unit 127. Is determined (S502).

  The setting information holding unit 127 refers to the image quality mode for the left screen and the image quality mode for the right screen held by the setting information holding unit 127 when the image duplicating unit 129 determines to perform duplication in the duplicate multi-display mode. Then, it is determined whether the image quality mode for the left screen and the image quality mode for the right screen are the same (S504). If the setting information holding unit 127 determines that the image quality mode for the left screen and the image quality mode for the right screen are the same, the setting information holding unit 127 determines that the left and right images are completely the same, and sets “image quality setting target” as “image quality setting target”. In order to determine whether or not to change, the process proceeds to S504. When the image quality mode for the left screen is different from the image quality mode for the right screen, the setting information holding unit 127 ends the process without changing the “image quality setting target”.

  When it is determined that the image quality mode for the left screen and the image quality mode for the right screen are the same, the setting information holding unit 127 determines whether the “image quality setting target” of the image quality setting information is “all images”. (S504). When the “image quality setting target” is “all images”, the setting information holding unit 127 changes the “image quality setting target” to “left image” (S505). The setting information holding unit 127 ends the process without changing the “image quality setting target” when the “image quality setting target” is set to “left image” or “right image” instead of “all images”. To do.

  As described above, in the display device 3, when the image data is duplicated, the left and right image quality modes match, and the “image quality setting target” is set to “all images”, the setting information The holding unit 127 automatically changes the “image quality setting target”. Therefore, the display device 3 can perform image processing on one of the first image data and the duplicated second image data without the user manually switching the setting.

  In addition, when the display control unit 12 (screen composition unit 123) determines to perform duplication in the duplication multi-display mode, the display control unit 12 (screen synthesis unit 123) sets the first image data (for example, first image data) among the plurality of image data to the first. A plurality of image data is displayed without superimposing the output device information on the at least one other image data (for example, the second image data) while superimposing the output device information which is information related to the photographing device 5 that output the image data. Display on the unit 13. For example, when the display control unit 12 determines to perform replication in the replication multi-display mode, the display device information is arranged and displayed at a position corresponding to the first image data, and is displayed at a position corresponding to the second image data. The output device information is not arranged and the output device information is not displayed. By doing in this way, it can prevent that the same information is displayed on the several location of the display part 13, and it becomes difficult to see an image.

[Effects of the display device 3 of the third embodiment]
As described above, the display device 3 includes the image duplicating unit 129 that duplicates the first image data acquired by the first image acquiring unit 111 and generates second image data. Since the display device 3 has such a configuration, the display device 3 automatically changes a target to be subjected to image processing based on information indicating whether the image is duplicated and whether the image quality mode is the same. be able to. Therefore, in the use case of displaying the input first image data and the duplicated second image data at the same time, there is an effect that the user does not need to manually switch the image quality setting target.

<Fourth Embodiment>
In the first to third embodiments, the display device 1 to the display device 3 determine image data or a region to be subjected to image processing or display output device information. On the other hand, in the third embodiment, image data or a region that is an object on which an electronic device that outputs an image to a display device or a display panel performs image processing or displays output device information. This is different from the first to third embodiments in that it determines and outputs an image after image processing or an image after superimposing output device information to a display device or a display panel.

  The electronic device according to the fourth embodiment is, for example, a computer that outputs an image to a display device or a display panel. The computer executes a program stored in a recording medium such as a CD-ROM, DVD, or hard disk, and is equivalent to the image acquisition unit 11 and the display control unit 12 in the first embodiment and the second embodiment. Function can be realized.
