That is, all configurations in which the embodiments and their modifications are combined are also included in the present invention.

Example 1
FIG. 1 is a device configuration diagram showing an imaging device 1, a display device 2, and an image processing device 100.

  The imaging device 1 is a digital video camera that captures a subject, acquires an original image, and outputs a plurality of image signals generated based on the original image. It is assumed that the original image acquired by the imaging apparatus 1 is an image having a resolution of 4K (4096 × 2160). The original image is not limited to an image with 4K resolution. The original image may be a 2K or 8K image. The imaging device 1 generates four image signals based on the original image and outputs them from different output terminals. Assume that the imaging apparatus 1 outputs an image signal with an SDI signal conforming to the Serial Digital Interface (SDI) standard. The format of the plurality of image signals generated from the original image by the imaging apparatus 1 will be described later.

  The display device 2 is a display device that displays an image on a screen based on an image signal acquired from the image processing device 100. For example, it is assumed that the display device 2 is a liquid crystal display. The display device 2 may be an organic EL display. The display device 2 may be a projector that projects and displays an image on a screen. In addition, the transmission path between the image processing apparatus 100 and the display apparatus 2 is described as a single transmission path in FIG. 1, but a plurality of transmissions are performed in the same manner as between the imaging apparatus 1 and the image processing apparatus 100. It may be a road.

  The image processing device 100 is an image processing device that generates and outputs an image to be displayed on the display device 2 based on a plurality of image signals acquired from the imaging device 1. The image processing apparatus 100 is assumed to be, for example, a personal computer (PC). Note that the image processing device 100 may be provided inside the display device 2 and constitute an integral display device.

  The image processing apparatus 100 can output an image subjected to image processing to the display device 2. Here, the image processing is assumed to be edge enhancement processing, monochrome display processing, false color display processing, blue-only display processing, and the like. The edge enhancement process is a process for coloring and displaying an area corresponding to the contour portion of an image. The monochrome display process is a process for displaying an image in monochrome. The false color process is a process of coloring with a different color for each luminance level of an image. The blue-only display process is a process that removes the red and green components of the image and displays only the blue component in monochrome. Note that the image processing may be image processing other than the processing described above.

  Further, the image processing apparatus 100 can generate a specific image for confirming the effect when image processing is performed on the input image and output the specific image to the display apparatus 2. The image processing apparatus 100 acquires an instruction as to whether or not a user outputs a specific image via an input interface (not shown), and generates and outputs a specific image when an instruction to output the specific image is acquired. Execute the process. Note that the image processing apparatus 100 may generate and output a specific image in response to obtaining an instruction to execute image processing.

  FIG. 2 is an apparatus configuration diagram of the image processing apparatus 100. The image processing apparatus 100 includes input terminals 101a to 101d, an image signal determination unit 102, an instruction input unit 103, and an output processing unit 110. The input terminals 101a to 101d are input terminals for acquiring different image signals from the imaging device 1, respectively. For example, it is assumed that the input terminals 101a to 101d are input terminals conforming to the Serial Digital Interface standard (SDI standard). The input terminals 101a to 101e may be input terminals conforming to the HDMI (registered trademark) standard. The input terminals 101a to 101d output the input image signals to the image signal determination unit 102 and the output processing unit 110, respectively.

  The image signal determination unit 102 is a determination circuit that determines the data format of the image signal input to the input terminals 101a to 101d. The image signal determination unit 102 is a determination circuit that determines whether or not an image signal is normally input to the input terminals 101a to 101d.

  Here, the relationship between an original image and a plurality of image signals output from the imaging device 1 will be described. FIG. 3 is a schematic diagram illustrating an original image and a plurality of thinned images generated by thinning pixels of the original image at a predetermined interval. As shown in the upper left of the original image, a plurality of image signals generated from the original image include two pixels in the horizontal direction and one pixel (one line) in the vertical direction for every two pixels constituting the original image. It corresponds to each of the images A to D extracted at intervals. Such a method is the 2-Sample Interleave method (2SI method). Each of the plurality of image signals generated by the 2SI method can form an image corresponding to the original image.

  The image signal corresponding to the thinned image is not limited to the above example. The plurality of thinned-out image signals are image signals of different pixels in the original image, and any image signal corresponding to an image with a reduced resolution of the original image may have any thinning interval or number of image signals. For example, two image signals obtained by extracting every other pixel of the original image may be used. Further, it can be said that the plurality of thinned images are images from which an original image can be obtained by superimposing.

  FIG. 4 is a schematic diagram illustrating an original image and a plurality of divided images generated by dividing the original image. In this case, the plurality of image signals respectively correspond to four divided images A to D obtained by dividing the original image into two in the horizontal direction and two in the vertical direction. Such a method is the Square Division method (SqDiv method). The plurality of image signals generated by the SqDiv method form images corresponding to the upper left, lower left, lower right, and upper right of the original image, respectively, in order to display an image corresponding to the original image, It is necessary to generate a composite image from the image signal.

  The imaging apparatus 1 adds video signal format information indicating how a plurality of image signals are generated as metadata to each image signal and outputs the metadata. FIG. 6 is a diagram illustrating an example of video signal format information. The video signal format information includes information on resolution, frame rate, I / P conversion type, color format, color depth, division method, and link code (arrangement of each image signal in the original image). Here, it is assumed that the division method is one of two types of 2SI method and SqDiv method. In the case of an SqDiv image signal, the link code includes “A”, “B” in the upper right, “C” in the lower left, “D” in the lower right, and “D” in the upper left image at the time of division. "Is entered. In the case of a 2SI image signal, the link code includes “A”, “B” in the upper right, and “C” in the upper left if the image signal is composed of two pixels at the upper left in a predetermined area of the original image. ", And the information on the lower right is" D ".

  The image signal determination unit 102 detects a valid image signal among the image signals input to the input terminals 101a to 101d. The image signal determination unit 102 determines whether or not a plurality of input image signals are image signals generated by the 2SI method from the video signal format information added to any one of the valid image signals. Determine whether.

  Note that the image signal determination unit 102 determines whether or not the plurality of input image signals are image signals generated by the 2SI method from the video signal format information added to all the image signals acquired from each input terminal. It may be determined. Further, the image signal determination unit 102 determines whether or not all of the plurality of image signals generated from the original image are normally input. The image signal determination unit 102 outputs the determination result to the output processing unit 110.

  The instruction input unit 103 outputs an instruction as to whether or not to output a specific image to the output processing unit 110 in accordance with a user operation. The instruction input unit 103 may generate and output a specific image in response to obtaining an instruction to execute image processing in response to a user operation.

  The output processing unit 110 is a processing circuit for generating and outputting an image (output image) to be displayed by the display device 2 from a plurality of acquired image signals. The output processing unit 110 can generate and output a specific image for confirming the effect of performing predetermined image processing on the image based on the input image signal in accordance with an instruction from the user. . FIG. 5 is a block diagram illustrating functional blocks of the output processing unit 110. The output processing unit 110 includes an input unit 111, a composition processing unit 112, an image processing unit 113, a reduction processing unit 114, a display image generation unit 115, a control unit 116, and a memory 117.

  The input unit 111 is an input interface that acquires the image signals a to d from the input terminals 101 a to 101 d. The input unit 111 outputs image signals a to d.

  The composition processing unit 112 is a composition processing circuit that generates a composite image corresponding to the original image based on the image signals a to d.

  The image processing unit 113 is an image processing circuit that performs specified image processing on an image based on an input image signal and outputs the image. The image processing that can be executed by the image processing unit 113 is the above-described image processing, for example, monochrome display processing.

  The reduction processing unit 114 is a scaling circuit that executes reduction processing. For example, the reduction processing unit 114 can reduce a 4K resolution image to a 2K resolution image.

  The display image generation unit 115 is a generation unit that generates a specific image for comparing and confirming the effects of image processing. The display image generation unit 115 is configured to check the effect of the image processing executed by the image processing unit 113, the processed image A subjected to image processing, the processed image B subjected to image processing different from the processed image A, To generate a specific image arranged side by side. For example, it is assumed that the display image generation unit 115 generates a specific image in which a processed image A subjected to image processing including black and white image processing and a processed image B not subjected to black and white image processing are arranged side by side.

  Note that the display image generation unit 115 may generate a specific image by arranging a plurality of images that have been subjected to different image processing. For example, the specific image may be generated by arranging the processed image C that has been subjected to image processing at a certain intensity and the processed image D that has been subjected to image processing at a different intensity from the processed image C. In this case, the image processing performed on the processed image C and the processed image D is the same type of image processing.

  The control unit 116 is a control circuit for controlling the operation of each functional block of the output processing unit 110. The control unit 116 is assumed to be an arithmetic processing circuit such as a CPU that controls the operation of each functional block by reading and executing the program and parameters stored in the memory 117.

  The memory 117 is a storage medium in which the control unit 116 stores a program for executing the embodiment of the present application and can be read by the control unit 116. The memory 117 is assumed to be a nonvolatile storage medium. Note that the memory 117 may be configured by a combination of a plurality of storage media, and may include a volatile storage medium and a nonvolatile storage medium.

  The output unit 118 is an output interface that outputs a display image for the display device 2 to display an image.

  FIG. 7 is a flowchart showing display image generation processing of the output processing unit 110. The output processing unit 110 repeatedly executes the display image generation process shown in FIG. 7 while the image processing apparatus 100 is in operation.

  In step S701, the control unit 116 determines whether the user has instructed execution of image processing. Specifically, the control unit 116 determines that the user has instructed execution of image processing when the instruction input unit 103 acquires a signal instructing execution of image processing by the user. If the control unit 116 determines that the user has not instructed execution of image processing, the process proceeds to S712. If the control unit 116 determines that the user has instructed execution of image processing, the process proceeds to S702. Here, a description will be given assuming that a monochrome conversion process (monochrome process) is instructed as the image process.

  In step S702, the control unit 116 determines whether the user has instructed execution of comparison display. Specifically, the control unit 116 determines that the user has instructed execution of comparison display when the user obtains a signal instructing execution of comparison display from the instruction input unit 103. If the control unit 116 determines that the user has not instructed execution of the comparison display, the process proceeds to S710. When the control unit 116 determines that the user has instructed execution of comparison display, the process proceeds to S703.

  In step S <b> 703, the control unit 116 determines whether the plurality of input image signals are generated by the 2SI method. Specifically, based on the determination result acquired from the image signal determination unit 102, the control unit 116 determines whether or not a plurality of input image signals are generated by the 2SI method. If the control unit 116 determines that the plurality of input image signals are not generated by the 2SI method, the process proceeds to S706. When the control unit 116 determines that the plurality of input image signals are generated by the 2SI method, the process proceeds to S704.

  In step S <b> 704, the control unit 116 controls the image processing unit 113 to perform image processing on an image based on any one of the input image signals. For example, it is assumed that the image processing unit 113 performs monochrome display processing on the image D based on the image signal d. The image processing unit 113 outputs the image D ′ subjected to the monochrome display process to the display image generation unit 115. The process proceeds to S705.

  In step S <b> 705, the display image generation unit 115 generates a specific image in which the image A based on the image signal a and the image D ′ are arranged and outputs the specific image to the output unit 118. Note that the control unit 116 selects two image signals whose pixels are not adjacent to each other in the original image as two images constituting the specific image. For example, a specific image may be generated using an image C ′ obtained by performing image processing on an image B based on the image signal b and an image C based on the image signal c. The process proceeds to S713.

  In S713, the output unit 118 outputs the acquired image as a display image to the display device 2.

  FIG. 8 is a schematic diagram showing an image displayed on the display device 2 based on the generated specific image. For example, the display image generation unit 115 arranges the image A on the left side and the image D ′ on the right side. By displaying an image that has been subjected to image processing and an image that is not the image side by side with respect to the image corresponding to the original image, the user can easily confirm the effect of the image processing.

  When a comparison display for confirming the effect of image processing is performed on a plurality of image signals generated by the 2SI method by the above-described series of processing, a specific image is generated and output without performing synthesis processing. It becomes possible to do. Therefore, it is possible to generate a specific image that can suitably check the effect of image processing while reducing the load on the image processing apparatus 100.

  If the control unit 116 determines in step S703 that the plurality of input image signals are not generated by the 2SI method, the control unit 116 combines the plurality of image signals with the combination processing unit 112 in step S706. The composition processing unit 112 is controlled to generate an image. When an error does not occur in a plurality of image signals, for example, in the transmission process, the composite image is the same image as the original image. The process proceeds to S707.

  In step S707, the control unit 116 controls the reduction processing unit 114 so as to generate a reduced image by reducing the composite image. The reduction processing unit 114 outputs the generated reduced image to the display image generation unit 115 (image E) and the image processing unit 113 (image F). The process proceeds to S708.

  In step S <b> 708, the control unit 116 controls the image processing unit 113 to execute image processing on the image F. Assume that the image processing unit 113 performs monochrome display processing on the image F. The image processing unit 113 outputs the image F ′ subjected to the monochrome display process to the display image generation unit 115. The process proceeds to S709.

  In step S <b> 709, the display image generation unit 115 generates a specific image in which the image E and the image F ′ are arranged and outputs the specific image to the output unit 118. The process proceeds to S713.

  When the plurality of input image signals are not image signals generated by the 2SI method, the specific image is generated by using the synthesized image corresponding to the original image generated from the plurality of image signals by the processing of S706 to S709. Can be output.

  If the control unit 116 determines in step S702 that the user has not instructed execution of comparison display, the control unit 116 generates a composite image in which a plurality of image signals are combined in the combination processing unit 112 in step S710. In this manner, the synthesis processing unit 112 is controlled. The composition processing unit 112 outputs the composite image to the image processing unit 113. The process proceeds to S711.

  In step S711, the control unit 116 controls the image processing unit 113 to perform image processing on the composite image. For example, it is assumed that the image processing unit 113 performs monochrome display processing on the composite image. The image processing unit 113 outputs the composite image that has been subjected to the monochrome display process to the output unit 118. The process proceeds to S713.

  If the control unit 116 determines in step S701 that the user has not instructed execution of image processing, the control unit 116 combines the plurality of image signals in the combination processing unit 112 in step S712. The synthesis processing unit 112 is controlled so as to generate a synthesized image. The composition processing unit 112 outputs the composite image to the output unit 118. The process proceeds to S713.

  As described above, the image processing unit 113 performs the image processing on the image based on any one of the plurality of image signals corresponding to the thinned image obtained by thinning the pixels of the original image and the other image. A specific image in which images based on signals are arranged side by side is generated. Therefore, when the plurality of input image signals are image signals that can individually display an image corresponding to the original image, the effect of the image processing can be obtained without executing the process of combining the plurality of image signals. An image that can be confirmed can be generated. As a result, it is possible to generate an image capable of suitably confirming the effect of the image processing while reducing the load on the circuit of the processing device.

  Note that three or more images may be arranged in the specific image. For example, an image based on the image signal a, an image based on the image signal b, which has been subjected to monochrome display processing, an image based on the image signal c, which has been subjected to edge enhancement processing, It is also possible to generate a specific image in which the images are arranged side by side.

  In the case where the plurality of image signals are image signals generated by the 2SI method, the specific image is generated from the image based on the image signal a and the image based on the image signal d. An image may be used. The control unit 116 can generate a specific image using an image based on an arbitrary image signal among the input image signals.

  Note that the specific image generated by the display image generation unit 115 is not limited to an image in which a processed image and an unprocessed image are arranged side by side. The display image generation unit 115 can generate a specific image by arranging and arranging images having different processing intensities of applied image processing. For example, when generating the specific image for confirming the effect of the edge enhancement processing, the display image generation unit 115 sets the detection sensitivity of the edge of one image to be higher than the detection sensitivity of the edge of the other image. A specific image for confirming the difference in sensitivity may be generated. Further, different types of image processing may be simultaneously applied to the images constituting the specific image so that the user can easily confirm the images subjected to the respective image processing simultaneously. .

  The display image generation unit 115 can also generate a specific image by arranging a plurality of three or more images that have been subjected to different image processing. For example, when the image signals input to the input terminals 101a to 101d are image signals obtained by thinning out the pixels of the original image, the display image generation unit 115 performs multiple image processing on images based on the image signals. These images may be arranged side by side to generate a specific image.

  FIG. 9 is a schematic diagram illustrating a specific image including processed images obtained by performing different image processing on images based on the four image signals a to d generated by the 2SI method. As illustrated in FIG. 8, a specific image may be generated by arranging four images including four image signals. Alternatively, a specific image may be generated by selecting three image signals and arranging the three images.

(Example 2)
When the image processing apparatus 100 according to the second embodiment determines that an image signal is not normally input to any one of the input terminals 101a to 101d, the image signal input to the other input terminal is A composite image is generated even for an image signal generated by the 2SI method.

  Since the configurations of the image processing apparatus 100 and the output processing unit 110 according to the second embodiment are the same as those according to the first embodiment, description thereof is omitted.

  FIG. 10 is a flowchart illustrating display image output processing according to the second embodiment. Steps denoted by the same reference numerals as those in FIG. 6 in the first embodiment are the same as those in the first embodiment, and thus description thereof is omitted. In the second embodiment, when the control unit 116 determines in S703 that the plurality of input image signals are generated by the 2SI method, the process proceeds to S801.

  In step S801, the control unit 116 determines whether a valid image signal is input to the input terminals 101a to 101d. Specifically, based on the result of the image signal determination unit 102 determining whether or not the image signal is normally input to the input terminals 101a to 101d, the control unit 116 normally outputs the image to the input terminals 101a to 101d. It is determined whether or not a signal is input. When the image signal determination unit 102 detects that a valid image signal is not input to at least one of the input terminals 101a to 101d, no valid image signal is input to the input terminals 101a to 101d. Is determined.

  In S801, when the control unit 116 determines that a valid image signal is input to the input terminals 101a to 101d, the process proceeds to S704. When the control unit 116 determines that a valid image signal is not input to the input terminals 101a to 101d, the process proceeds to S706.

  When image processing is performed on an image obtained by further reducing a composite image generated with a lack of image signals, it may be difficult to confirm the effect of the image processing originally obtained. By the above-described processing, when a plurality of image signals generated from an original image are not normally input, a specific image can be generated using an image signal that is input effectively among a plurality of input means. It becomes possible. Therefore, it is possible to suppress the influence of an ineffective image signal and appropriately check the effect of image processing.

(Example 3)
When the input image signal is an image signal corresponding to an image obtained by dividing the original image, the output processing unit 110 of the image processing apparatus 100 according to the third embodiment performs image processing on a part of the synthesized image. To generate a specific image.

  The output processing unit 110 according to the third embodiment does not include the reduction processing unit 114 as compared with the first embodiment. Other configurations are the same as those of the first embodiment.

  FIG. 11 is a flowchart illustrating display image output processing according to the third embodiment. Steps denoted by the same reference numerals as those in FIG. 6 in the first embodiment are the same as those in the first embodiment, and thus description thereof is omitted. In the third embodiment, when the control unit 116 determines in S703 that the plurality of input image signals are not generated by the 2SI method, the process proceeds to S706.

  In step S <b> 706, the control unit 116 controls the composition processing unit 112 so as to generate a composite image by combining the plurality of image signals with the composition processing unit 112. The composition processing unit 112 outputs the composite image to the image processing unit 113. The process proceeds to S901.

  In step S901, the control unit 116 controls the image processing unit 113 to perform image processing on a part of the composite image. For example, the image processing unit 113 performs black and white display processing on the right half of the composite image. FIG. 12 is a schematic diagram of a composite image that has been subjected to black and white display processing on the right half.

  The control unit 116 can control a region to be subjected to image processing in the composite image in accordance with a user instruction acquired from the instruction input unit 103. For example, it is assumed that the user can dynamically control the position of the boundary R between the region where image processing is performed and the region where image processing is not performed in the composite image.

  When the user dynamically controls the boundary R, the user can confirm the comparison between the case where the image processing is performed on the attention area and the case where the image processing is not performed.

  By performing the above processing, the user can confirm the effect of the image processing without performing the reduction processing. Therefore, the reduction processing unit 114 is not necessary, and the circuit scale can be reduced.

  It should be noted that various areas can be used as the area to be subjected to image processing instructed by the user as long as an arbitrary area in the composite image is designated.
