Description

  The present invention relates to a technique for capturing a still image.

  In general, when a still image is taken with an imaging device typified by a digital camera, a user looks at a live image (moving image) continuously displayed on a display interface, and performs composition, focus, exposure, and the like. After confirmation, input shooting instructions. On the other hand, Patent Document 1 describes a technique for distinguishing between a still image acquired simultaneously with shooting and recording of a moving image and a still image acquired when shooting of a moving image is not performed.

JP 2006-173908 A

  Even in an imaging system having an imaging device and a display device that displays an image transmitted from the imaging device and controls the imaging device, it is possible to capture a still image by a method similar to a general imaging method. For example, a live image continuously transmitted from the imaging device is displayed on the display device. The user views the live image and confirms the composition and the like, and then inputs a shooting instruction to the display device. The input shooting instruction is transmitted to the imaging apparatus, and the imaging apparatus that has received the shooting instruction performs shooting to generate a still image.

  In the imaging system described above, the shooting timing is delayed with respect to the actual photo opportunity by combining the time required to transmit and display the live image and the time required to transmit the shooting instruction. In addition, when communication between the imaging device and the display device is performed wirelessly, shooting immediately after the imaging device and the display device are activated requires time for setting wireless communication, and therefore a photo opportunity may be missed. . In addition, since power is used for transmission, reception, and display of live images, shooting may not be performed when the remaining battery level is low.

  For this reason, there is a need to capture a still image by inputting a shooting instruction to the imaging device without confirming a live image displayed on the display device. In such shooting, a still image can be taken easily and immediately without checking the composition or the like using a live image. For convenience of various processes performed after shooting, still images generated by shooting without displaying live images are distinguished from still images generated by normal shooting performed after displaying live images. It is desirable to be able to do it. Thereby, for example, a still image generated without confirmation by a live image can be preferentially displayed later, and the content can be confirmed by the user.

  With the technique described in Patent Document 1, it is possible to distinguish whether or not a moving image is captured by information added to a still image, but it is not possible to distinguish whether or not a moving image is displayed.

  The present invention provides a technique for capturing a still image that can be distinguished whether or not a live image is displayed when the still image is captured.

Received put et al, a second communication module for transmitting the imaging instruction to the imaging device, and an image display interface for displaying the live image in parallel with the reception of the live image is an imaging system having a.

  Further, the present invention provides a step in which a transmission detection unit that detects whether or not the live image is transmitted to a display device that displays the live image in parallel with reception of the live image continuously generated by the imaging module performs detection; When a shooting instruction is received from the display device by the communication module, the imaging module performs shooting to generate a still image, and the live image is transmitted before the shooting instruction is received. Transmission information indicating whether or not the information addition unit adds the transmission information to the still image generated based on the shooting instruction, and the storage module stores the still image with the transmission information added; Is an imaging method.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
First, a first embodiment of the present invention will be described. FIG. 1 shows a configuration example of an imaging system according to the present embodiment. The imaging system illustrated in FIG. 1 includes an imaging device 10 and a display device 20.

  The imaging apparatus 10 includes an imaging module 100, a first operation interface (first operation IF) 101, a first communication module 102, a transmission detection unit 103, a first control unit 104a, and a storage module 105. And have.

  The imaging module 100 (imaging device) continuously generates live images and performs shooting to generate still images. A live image is an individual image (an image generated for each frame) constituting a moving image. The live image includes image data for displaying the image. A still image is an image recorded on a nonvolatile recording medium. The still image includes image data for displaying the image. The number of pixels (resolution) of the live image and the still image may be different.

  The first operation interface 101 (first operation module, first operation device) receives an operation of a user who inputs a first imaging instruction. For example, the first operation interface 101 is a shutter button (release switch) provided in the imaging apparatus 10.

  The first communication module 102 (first communication interface, first communication device) transmits the live image to the display device 20 that displays the live image in parallel with the reception of the live image, and issues a second shooting instruction. Received from the display device 20.

  The transmission detection unit 103 detects whether a live image is transmitted to the display device 20. The display device 20 is a device that receives a live image from the imaging device 10 in order to display a live image. When a live image is transmitted to the display device 20 at the time of shooting, the live image is displayed on the display device 20, and the user can check the composition and the like by viewing the live image.

  The first control unit 104 a is a control module (control device) such as a CPU (Central Processing Unit) and controls the operation of the imaging apparatus 10. For example, the first control unit 104a performs imaging when a first imaging instruction is input via the first operation interface 101 or when a second imaging instruction is received by the first communication module 102. To control the imaging module 100 to generate a still image. The second imaging instruction is one of commands for controlling the imaging device 10 transmitted by the display device 20.

  In the present embodiment, the first control unit 104a includes an information adding unit 1040. The information adding unit 1040 transmits transmission information indicating whether or not a live image has been transmitted before the first imaging instruction is input or before the second imaging instruction is received. The image is added to the still image generated by the imaging module 100 based on the instruction or the second imaging instruction. The transmission information is information indicating whether or not a live image has been transmitted at the time of shooting, and is also information indicating whether or not the live image has been displayed by the display device 20 at the time of shooting.

  For example, the transmission information is added to the still image by embedding the transmission information in the still image file. For example, transmission information may be included in EXIF (Exchangeable Image File Format) information embedded in a still image file. The transmission information may be added to the still image by including the transmission information in a file different from the still image file and associating these files. For example, information that refers to a still image (for example, identification information (file name, etc.) of a still image file) may be included in a file including transmission information.

  The storage module 105 (storage device) is a non-volatile recording medium such as a memory built in the imaging apparatus 10 and stores a still image to which transmission information is added.

  The display device 20 includes a second operation interface (second operation IF) 200, a second communication module 201, an image display interface (image display IF) 202, and a second control unit 203a.

  The second operation interface 200 (second operation module, second operation device) receives an operation of a user who inputs a second imaging instruction. For example, the second operation interface 200 is a button (switch) provided on the display device 20. When the image display interface 202 is configured as a touch panel, the second operation interface 200 may be a button displayed on the image display interface 202 or the like.

  The second communication module 201 (second communication interface, second communication device) receives a live image from the imaging device 10 and captures a second shooting instruction input via the second operation interface 200. Transmit to device 10.

  The image display interface 202 (image display module, image display device) displays a live image in parallel with reception of the live image. In the display device 20, the reception of the live image and the display of the live image are performed as a set operation, for example.

  The second control unit 203 a is a control module (control device) such as a CPU, and controls the operation of the display device 20. For example, when the second communication module 201 receives a live image of one frame by the second communication module 201, the second control unit 203a converts the received live image to the second live image before receiving the live image of the next frame. The image is output to the image display interface 202, and the live image is displayed on the second image display interface 202. In the display device 20, the period from the start of reception of the live image of the first frame to the end of reception of the live image of the last frame and the display of the live image of the last frame from the start of display of the live image of the first frame. At least partly overlaps with the period until the end of.

  Communication between the imaging device 10 and the display device 20 performed by the first communication module 102 and the second communication module 201 may be either wireless communication or wired communication.

  The function of the first control unit 104a or the second control unit 203a is a function of the imaging device 10 or the display device 20, for example, including a program including an instruction for defining the operation of the first control unit 104a or the second control unit 203a. It can be realized as a software function by being read and executed by a computer. The program may be provided by a “computer-readable recording medium” such as a flash memory. In addition, the above-described program is transmitted from the computer storing the program in a storage device or the like to the imaging device 10 or the display device 20 via a transmission medium or by a transmission wave in the transmission medium. It may be input to the display device 20. Here, the “transmission medium” for transmitting the program is a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. Further, the above-described program may realize a part of the functions described above. Furthermore, the above-described program may be a so-called difference file (difference program) that can realize the above-described function in combination with a program already recorded in the computer.

  Below, the transmission detection part 103 demonstrates the example of the method of detecting the presence or absence of transmission of the live image with respect to the display apparatus 20. FIG. For example, the transmission detection unit 103 detects the presence / absence of transmission of a live image by detecting the state of a switch that switches between ON and OFF of the operation of the first communication module 102. When the switch state of the first communication module 102 is the ON state, the transmission detection unit 103 detects that a live image is being transmitted. Further, when the switch state of the first communication module 102 is in the OFF state, the transmission detection unit 103 detects that the live image is not transmitted. The switch state may be detected by mechanical detection or by electrical detection.

  Alternatively, the transmission detection unit 103 may detect the presence / absence of transmission of a live image by detecting the presence / absence of power supply to the first communication module 102. When power is supplied to the first communication module 102, the transmission detection unit 103 detects that a live image is being transmitted. In addition, when power is not supplied to the first communication module 102, the transmission detection unit 103 detects that the live image is not transmitted. The presence / absence of power supply may be detected by detecting a driving voltage or current input to the first communication module 102.

  Alternatively, the transmission detection unit 103 detects whether or not a display interface that displays an optical image or a live image of a subject that can be attached to and detached from the imaging device 10 is attached to the imaging device 10. The presence / absence of transmission of a live image may be detected. The imaging apparatus 10 is equipped with an OVF (Optical View Finder) that is a display interface that displays an optical image of a subject or an EVF (Electronic View Finder) that is a display interface that displays a live image generated by the imaging module 100. Is possible. It is possible to take a still image after the user confirms the composition or the like by looking at the OVF or EVF.

  In general, a display interface mounted on a display device has a larger display area than OVF or EVF mounted on an imaging device. Further, the visual field range captured by the OVF does not necessarily match the visual field range captured by the imaging lens. For this reason, when confirmation is performed using OVF or EVF, the composition or the like may not be sufficiently confirmed as compared with the case where confirmation is performed using a live image displayed on the display interface of the display device.

  In the present embodiment, the use of OVF or EVF and the use of the display device 20 are mutually exclusive. That is, when the OVF or EVF is attached to the imaging device 10, the live image is not transmitted. Only when the OVF or EVF is not attached to the imaging apparatus 10, the live image is transmitted.

  When the OVF or EVF is not attached to the imaging apparatus 10, the transmission detection unit 103 detects that a live image is being transmitted. When the OVF or EVF is attached to the imaging apparatus 10, the transmission detection unit 103 detects that the live image is not transmitted. Whether or not the OVF or EVF is attached to the imaging apparatus 10 may be detected by mechanical detection or electrical detection.

  FIG. 2 shows a specific configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 2 includes an imaging device 10, a display device 20, and an imaging lens 30.

  The imaging device 10 and the display device 20 are connected by wireless communication. The imaging device 10 and the display device 20 are not necessarily in contact with each other. A first operation interface 101 configured as a shutter button is disposed on the side surface of the imaging apparatus 10. When the user presses the first operation interface 101, the first photographing instruction is input. In addition, the display interface 40 that is OVF or EVF can be attached to the side surface of the imaging apparatus 10.

  An imaging lens 30 is attached to the front surface of the imaging device 10. The imaging lens 30 can be attached to and detached from the imaging device 10. The imaging device 10 and the imaging lens 30 may be configured integrally.

  An image display interface 202 is disposed on the back surface of the display device 20. The user can check the composition and the like by viewing the live image displayed on the image display interface 202.

  FIG. 3 shows an example of an operation procedure of the imaging apparatus 10. With reference to FIG. 3, the operation of the imaging apparatus 10 will be described. When a live image transmission instruction is received from the display device 20, the imaging module 100 starts generating a live image, and the first communication module 102 transmits the live image to the display device 20. In FIG. 3, the generation and transmission of live images are not shown.

  When the shooting mode process is started, the first control unit 104a causes the transmission detection unit 103 to detect whether or not a live image is transmitted to the display device 20 (step S100). Thereby, the transmission detection unit 103 detects whether or not a live image is transmitted to the display device 20. The result of detection performed by the transmission detection unit 103 is notified to the first control unit 104a.

  After the transmission detection unit 103 detects, the first control unit 104a determines whether or not the live image is transmitted based on the result of the detection performed by the transmission detection unit 103 (step S101). ). When it is determined that a live image is being transmitted, the information adding unit 1040 generates transmission information having a value of 1 (step S102). When it is determined that the live image is not transmitted, the information adding unit 1040 generates transmission information whose value is 0 (step S103). If transmission information has already been generated, the values of the transmission information may be rewritten without generating new transmission information in steps S102 and S103.

  As described above, the transmission information includes the live image before the first shooting instruction is input via the first operation interface 101 or before the second shooting instruction is received by the first communication module 102. Is information indicating whether or not transmission has been performed. The value of the transmission information may be a value that can distinguish whether or not a live image is transmitted, and may be other than 0 and 1.

  After the transmission information is generated, the first control unit 104a determines whether or not an instruction to capture a still image has been issued (step S104). When the first photographing instruction is input via the first operation interface 101 or when the second photographing instruction is received by the first communication module 102, it is determined that the photographing of the still image is instructed. . Further, when the first photographing instruction is not input via the first operation interface 101 and the second photographing instruction is not received by the first communication module 102, the photographing of the still image is instructed. It is determined that it is not.

  If it is determined that shooting of a still image has not been instructed, the process of step S108 is performed. In addition, when it is determined that shooting of a still image has been instructed, the first control unit 104a instructs the imaging module 100 to shoot a still image, and causes the imaging module 100 to perform shooting to generate a still image ( Step S105). As a result, the imaging module 100 performs imaging and generates a still image. The generated still image is output to the first control unit 104a.

  After the still image is generated, the information adding unit 1040 converts the transmission information generated in step S102 or step S103 into the still image generated based on the first shooting instruction or the second shooting instruction in step S105. It is added (step S106). After the transmission information is added to the still image, the first control unit 104a stores the still image to which the transmission information is added in the storage module 105 (step S107). As a result, the storage module 105 stores the still image to which the transmission information is added. When the transmission information is embedded in the still image, the transmission information is also stored in the storage module 105 by storing the still image in the storage module 105. When the still image and the transmission information are separated and are associated with each other, the still image and the transmission information are stored in the storage module 105 separately.

  After the still image is stored in the storage module 105, the first control unit 104a determines whether or not to end shooting (step S108). When an instruction to end shooting is input via the first operation interface 101, or when a command to end shooting is received by the first communication module 102, it is determined to end shooting. In addition, when an instruction to end shooting is not input via the first operation interface 101 and a command to end shooting is not received by the first communication module 102, it is determined that shooting is not ended. Is done.

  If it is determined that the shooting is to be terminated, the shooting mode process ends. If it is determined not to end the shooting, the process of step S100 is performed. After the process of step S107 is performed, the shooting mode process may be forcibly terminated without performing the determination of step S108.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. FIG. 4 shows a configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 4 includes an imaging device 11 and a display device 20.

If it is determined that the received command is not a command for requesting transmission of a still image, the first control unit 104b performs processing according to the received command (step S201). After processing according to the received command is performed, the imaging device 11 waits for a command transmitted from the display device 20. When it is determined that the received command is a command for requesting transmission of a still image, the first control unit 104b reads one of the still images stored in the storage module 105 (step S203).

  The first control unit 104b checks the transmission information added to the still image read from the storage module 105 in step S203 (step S204). The first control unit 104b determines whether or not the value of the transmission information checked in step S204 is 0 (step S205).

  If it is determined that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, the process of step S208 is performed. When it is determined that the value of the transmission information is 0, that is, when the live image is not transmitted when the still image is captured, the image selection unit 1041 corresponds to the transmission information whose value is 0. A still image is selected as a transmission target (step S206). The selected still image is output to the first communication module 102.

  After the still image to be transmitted is selected, the first control unit 104b causes the first communication module 102 to transmit the selected still image to the display device 20 (step S207). Accordingly, the first communication module 102 transmits the selected still image to the display device 20. The transmission of the still image may be performed by background processing of other processing performed by the imaging device 11.

  After the still image is transmitted, the first control unit 104b determines whether all the still images stored in the storage module 105 have been read (step S208). If it is determined that all the still images stored in the storage module 105 have been read, the processing shown in FIG. 5 ends. If it is determined that there is a still image that has not yet been read, the process of step S203 is performed.

  When the still image and the transmission information are separated and associated with each other, only the transmission information may be read in step S203, and the still image associated with the transmission information may be read in step S206.

  When a command is not received from the display device 20 and a still image transmission instruction is input via the first operation interface 101, the processing after step S203 may be performed. Therefore, the processing of steps S200 to S202 is not essential for this embodiment.

  In step S207, a thumbnail image of a still image may be transmitted to the display device 20. By displaying the thumbnail image on the display device 20, the user can easily confirm whether or not a desired subject has been photographed.

  Only one still image to which transmission information indicating that a live image is not transmitted may be transmitted to the display device 20. For example, after a list of thumbnail images of all still images stored in the storage module 105 is displayed on the display device 20, the user designates a thumbnail image. When the transmission information added to the still image corresponding to the designated thumbnail image indicates that the live image is not transmitted, the still image with the transmission information added is displayed on the display device 20. The Further, only a thumbnail image of one still image may be transmitted to the display device 20.

  After the still image generated without transmitting the live image is transmitted to the display device 20, the imaging device 11 transmits the still image generated after the transmission of the live image to the display device 20. Also good. That is, the image selection unit 1041 further selects a still image to which transmission information indicating that a live image has been transmitted is added, and the first communication module 102 does not transmit a live image. Only after the still image to which the transmission information indicating “” is added is transmitted, the still image to which the transmission information indicating that the live image has been transmitted may be transmitted to the display device 20.

  In the present embodiment, it is possible to preferentially transmit a still image generated without transmitting a live image to the display device 20. When the display device 20 displays the still image on the image display interface 202, the user can preferentially check the composition of the still image. In addition, it is possible to reduce the effort for the user to select a still image stored in the storage module 105 in order to confirm the composition of a still image generated without transmitting a live image.

(Third embodiment)
Next, a third embodiment of the present invention will be described. FIG. 6 shows a configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 6 includes an imaging device 10 and a display device 21. Since the configuration of the imaging device 10 has already been described, description thereof is omitted.

  The display device 21 includes a second operation interface 200, a second communication module 201, an image display interface 202, and a second control unit 203b. The description of the configuration that has already been described is omitted.

  In the present embodiment, the second control unit 203b includes an image designation unit 2030. The image designation unit 2030 generates designation information for designating a still image to be transmitted from identification information corresponding to transmission information indicating that the live image is not transmitted. The identification information is information for identifying a still image to which transmission information is added (for example, a still image file name). The first communication module 102 transmits transmission information, identification information, and a still image to be transmitted to the display device 20, and receives designation information from the display device 20. The second communication module 201 receives transmission information, identification information, and a still image to be transmitted from the imaging device 10, and transmits designation information to the imaging device 10. The function of the second control unit 203b may be realized by software.

  FIG. 7 shows an example of an operation procedure of the imaging apparatus 10. With reference to FIG. 7, the operation of the imaging apparatus 10 will be described. The operation shown in FIG. 7 is performed after the operation shown in FIG. 3 is performed.

  When the process is started, the imaging device 10 waits for a command transmitted from the display device 21. When reception of a command is detected, the first control unit 104a causes the first communication module 102 to receive the command (step S300). As a result, the first communication module 102 receives a command from the display device 21. The received command is output to the first control unit 104a.

  After the command is received, the first control unit 104a causes the first communication module 102 to transmit a response to the command to the display device 21 (step S301). As a result, the first communication module 102 transmits a response to the command to the display device 21.

  After the response to the command is transmitted, the first control unit 104a determines whether or not to end the process related to the command (step S302). For example, if a command for notifying the end of processing is received in step S300, it is determined that the processing related to the command is to be ended, and otherwise, it is determined not to end the processing related to the command.

  If it is determined that the process related to the command is to be terminated, the process illustrated in FIG. 7 is terminated. If it is determined not to end the process related to the command, the process of step S300 is performed.

  FIG. 8 shows an example of the operation procedure of the display device 21. The operation of the display device 21 will be described with reference to FIG.

  When the process is started, the second control unit 203b causes the second communication module 201 to transmit a command requesting transmission of transmission information and still image identification information to the imaging apparatus 10 (step S350). ). As a result, the second communication module 201 transmits a command requesting transmission of the transmission information and the still image identification information to the imaging apparatus 10.

  The command transmitted by the display device 21 is received by the imaging device 10 in step S300 in FIG. In step S301, the first control unit 104a displays, for the first communication module 102, transmission information stored in the storage module 105 and identification information of a still image to which the transmission information is added. 21 to send. Thereby, the first communication module 102 transmits the transmission information stored in the storage module 105 and the identification information of the still image to which the transmission information is added to the display device 21.

  After the command is transmitted in step S350, the second control unit 203b causes the second communication module 201 to receive the transmission information and identification information transmitted by the imaging device 10 (step S351). As a result, the second communication module 201 receives the transmission information and the identification information transmitted by the imaging device 10. The received transmission information and identification information are output to the second control unit 203b.

  The transmission information received by the display device 21 and the identification information are associated with each other. For example, the transmission information and the identification information are transmitted to the display device 21 in the same communication frame. The transmission information and the identification information may be stored in the same file. The transmission information may be associated with the identification information by including the identification information in a file different from the transmission information file and including information referring to the other in one of the files.

  After the transmission information and the identification information are received, the second control unit 203b examines the received transmission information (step S352). The second control unit 203b determines whether or not the value of the transmission information checked in step S352 is 0 (step S353). If it is determined that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, the process of step S357 is performed. When it is determined that the value of the transmission information is 0, that is, when the live image is not transmitted when the still image is captured, the image designating unit 2030 corresponds to the transmission information whose value is 0. Designation information for designating a still image with the transmission information added as a transmission target is generated from the identification information (step S354). The identification information and the designation information may be the same. The generated designation information is output to the second communication module 201.

  After the designation information is generated, the second control unit 203b causes the second communication module 201 to transmit a command that includes the generated designation information and requests transmission of a still image to the imaging apparatus 10 (Step S1). S355). As a result, the second communication module 201 transmits a command that includes the generated designation information and requests transmission of a still image to the imaging device 10.

  The command transmitted by the display device 21 is received by the imaging device 10 in step S300 in FIG. In step S <b> 301, the first control unit 104 a causes the first communication module 102 to transmit a still image designated by the designation information included in the received command to the display device 21. This still image is a still image stored in the storage module 105. Thereby, the first communication module 102 transmits the still image specified by the specification information included in the received command to the display device 21.

  After the command is transmitted in step S355, the second control unit 203b causes the second communication module 201 to receive the still image transmitted by the imaging device 10 (step S356). As a result, the second communication module 201 receives the still image transmitted by the imaging device 10. The received still image is output to the second control unit 203b.

  After the still image is received, the second control unit 203b determines whether transmission information of all the still images in the imaging device 10 has been confirmed (Step S357). For example, in the imaging apparatus 10, every time a command requesting transmission of transmission information and identification information of a still image is received, whether or not the first control unit 104a has transmitted transmission information of all still images. judge. When transmission information of all still images is transmitted, the first control unit 104a performs processing to transmit a response indicating that the transmission information of all still images has been confirmed to the display device 21. When this response is received by the second communication module 201, it is determined that the transmission information of all the still images in the imaging device 10 has been confirmed. In other cases, the transmission information of still images that have not been confirmed yet is determined. It is determined that there is.

  When it is determined that the transmission information of all the still images in the imaging device 10 has been confirmed, the process illustrated in FIG. 8 ends. If it is determined that there is still image transmission information that has not yet been confirmed, the process of step S350 is performed.

  The display device 21 may not transmit a command requesting transmission of the transmission information and the still image identification information. For example, when a transmission instruction for transmission information and still image identification information is input via the first operation interface 101, the imaging apparatus 10 transmits the transmission information and still image identification information to the display device 21. May be. Therefore, the process of step S350 is not essential for this embodiment.

  Further, after the still image is received in step S355, the received still image may be displayed by the image display interface 202. In step S356, a thumbnail image of a still image may be received.

  Further, in the process shown in FIG. 8, all the still images to which transmission information indicating that no live image is transmitted are added are transmitted to the display device 21, but no live image is transmitted. Only one still image (or only its thumbnail image) to which transmission information indicating this may be added may be transmitted to the display device 21. For example, the process illustrated in FIG. 8 may be terminated without performing the process of step S357. The display device 21 repeatedly performs the process excluding the process of step S357 from the entire process illustrated in FIG. 8, whereby all the still images to which transmission information indicating that no live image is transmitted are added. The display device 21 may receive it.

  After the still image generated without the transmission of the live image is received by the display device 21, the display device 21 may receive the still image generated after the transmission of the live image. That is, the image designation unit 2030 further generates designation information from the identification information corresponding to the transmission information indicating that the live image has been transmitted, and the second communication module 201 has transmitted the live image. Only after a still image to which transmission information indicating that there is no transmission is received may be received from the imaging device 10, a still image to which transmission information indicating that a live image has been transmitted is added.

  In the present embodiment, a still image generated without transmitting a live image can be preferentially transmitted to the display device 21. The display device 21 displays the still image on the image display interface 202, so that the user can preferentially check the composition of the still image. In addition, it is possible to reduce the effort for the user to select a still image stored in the storage module 105 in order to confirm the composition of a still image generated without transmitting a live image.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described. FIG. 9 shows a configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 9 includes an imaging device 12 and a display device 20. Since the configuration of the display device 20 has already been described, the description thereof is omitted.

  The imaging device 12 includes an imaging module 100, a first operation interface 101, a first communication module 102, a transmission detection unit 103, a first control unit 104 c, and a storage module 105. The description of the configuration that has already been described is omitted.

  In the present embodiment, the first control unit 104c includes an information addition unit 1040, an image selection unit 1041, and an image processing unit 1042. Since the information addition unit 1040 and the image selection unit 1041 have already been described, description thereof will be omitted. The image processing unit 1042 performs image processing on the still image selected by the image selection unit 1041. The first communication module 102 transmits the still image processed by the image processing unit 1042 to the display device 20. The function of the first control unit 104c may be realized by software.

  For example, the image processing performed by the image processing unit 1042 is a process of bringing the still image selected by the image selection unit 1041 closer to an image taken with a film camera. For example, the image processing unit 1042 performs processing for adding granular noise to the still image selected by the image selection unit 1041. Alternatively, the image processing unit 1042 performs a process for enhancing a color, a process for blurring a color, a process for converting to a two-tone image of white and black, and a periphery of an image for the still image selected by the image selection unit 1041 A process for darkening a part, a process for enhancing contrast, and the like may be performed.

  Alternatively, the image processing unit 1042 may perform processing for adding a frame or a shooting date and time to the still image selected by the image selection unit 1041. Alternatively, image processing parameters corresponding to the above-described various image processes are stored in the storage module 105, and the image processing unit 1042 randomly selects the image processing parameters stored in the storage module 105 and selects them by the image selection unit 1041. Image processing based on the selected image processing parameter may be performed on the selected still image.

  FIG. 10 shows an example of an operation procedure of the imaging device 12. The operation of the imaging device 12 will be described with reference to FIG. The operation shown in FIG. 10 is performed after the operation shown in FIG. 3 is performed.

  The processing in steps S400 to S406 is the same as the processing in steps S200 to S206 in FIG. After the still image is selected in step S406, the image processing unit 1042 performs image processing on the still image selected by the image selection unit 1041 (step S407).

  After the image processing is performed, the first control unit 104b causes the first communication module 102 to transmit the still image subjected to the image processing to the display device 20 (step S409). As a result, the first communication module 102 transmits the still image on which image processing has been performed to the display device 20. After the still image is transmitted, the process shown in FIG. 10 ends.

  If it is determined in step S405 that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, the image selection unit 1041 corresponds to the transmission information whose value is 1. A still image is selected as a transmission target (step S408). The selected still image is output to the first communication module 102 and transmitted to the display device 20 by the first communication module 102 in step S409.

  After the process of step S409 is performed, the process similar to the process of step S208 of FIG. 5 may be performed to repeat the transmission of the still image.

  When a command is not received from the display device 20 and a still image transmission instruction is input via the first operation interface 101, the processing after step S403 may be performed. Therefore, the processing of steps S400 to S402 is not essential for this embodiment.

  Further, the process of step S408 may not be performed. That is, the still image generated after the live image is transmitted may not be transmitted to the display device 20. Therefore, the process of step S408 is not essential for this embodiment.

  In the present embodiment, it is possible to perform image processing on a still image generated without transmitting a live image, distinguishing it from a still image generated after transmitting a live image. Thereby, for example, a still image simulating an image taken with a film camera can be generated.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described. FIG. 11 shows a configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 11 includes an imaging device 10 and a display device 22. Since the configuration of the imaging device 10 has already been described, description thereof is omitted.

  The display device 22 includes a second operation interface 200, a second communication module 201, an image display interface 202, and a second control unit 203c. The description of the configuration that has already been described is omitted.

  In the present embodiment, the second control unit 203 c includes an image selection unit 2031 and an image processing unit 2032. The image selection unit 2031 selects a still image to which transmission information indicating that a live image is not transmitted is added from among the still images received by the second communication module 201. The image processing unit 2032 performs image processing on the still image selected by the image selection unit 2031. The image processing performed by the image processing unit 2032 is the same as the image processing performed by the image processing unit 1042 in the fourth embodiment. The first communication module 102 transmits the still image and transmission information stored in the storage module 105 to the display device 22. The second communication module 201 receives a still image and transmission information from the imaging device 10. The function of the second control unit 203c may be realized by software.

  FIG. 12 shows an example of an operation procedure of the display device 22. The operation of the display device 22 will be described with reference to FIG.

  When the process is started, the second control unit 203c causes the second communication module 201 to transmit a command requesting transmission of a still image to the imaging device 10 (step S500). As a result, the second communication module 201 transmits a command requesting transmission of a still image to the imaging apparatus 10.

  The command transmitted by the display device 22 is received by the imaging device 10 in step S300 in FIG. In step S <b> 301, the first control unit 104 a causes the first communication module 102 to transmit one of the still images stored in the storage module 105 to the display device 22. As a result, the first communication module 102 transmits one of the still images stored in the storage module 105 to the display device 22.

  When the transmission information is embedded in the still image, the transmission information is also transmitted by transmitting the still image. When the still image and the transmission information are separated and are associated with each other, the imaging device 10 may transmit the still image and the transmission information at the same time, or the imaging device 10 sequentially transmits the still image and the transmission information. You may send it.

  After the command is transmitted in step S500, the second control unit 203c causes the second communication module 201 to receive the still image and the transmission information transmitted by the imaging device 10 (step S501). Thereby, the second communication module 201 receives the still image and the transmission information transmitted by the imaging device 10. The received still image and transmission information are output to the second control unit 203c.

  After the still image and the transmission information are received, the second control unit 203c checks the transmission information added to the received still image (step S502). The second control unit 203c determines whether or not the value of the transmission information checked in step S502 is 0 (step S503). When it is determined that the value of the transmission information is 0, that is, when a live image is not transmitted when a still image is captured, the image selection unit 2031 has a still image corresponding to the transmission information whose value is 0. Is selected as a display target (step S504).

  After the still image is selected, the image processing unit 2032 performs image processing on the still image selected by the image selection unit 2031 (step S505). After the image processing is performed, the second control unit 203c causes the image display interface 202 to display the still image subjected to the image processing (Step S507). As a result, the image display interface 202 displays a still image on which image processing has been performed. After the still image is displayed, the process shown in FIG. 12 ends.

  If it is determined in step S503 that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, the image selection unit 2031 determines that the transmission information has a value of 1. A corresponding still image is selected as a display target (step S506). The selected still image is output to the image display interface 202, and is displayed by the image display interface 202 in step S507.

  After the process of step S506 is performed, the same process as the process of step S357 of FIG. 8 may be performed to repeatedly receive the still image and the transmission information.

  The display device 22 may not transmit a command requesting transmission of a still image. For example, the imaging device 10 may transmit the still image and transmission information to the display device 22 when a still image transmission instruction is input via the first operation interface 101. Therefore, the process of step S500 is not essential for this embodiment.

  Moreover, the process of step S507 does not need to be performed. That is, the image display interface 202 may not display a still image. Therefore, the process of step S507 is not essential for this embodiment.

  In the present embodiment, it is possible to perform image processing on a still image generated without transmitting a live image, distinguishing it from a still image generated after transmitting a live image. Thereby, for example, a still image simulating an image taken with a film camera can be generated. Further, since the display device 22 performs image processing, more complicated image processing using the second control unit 203c of the display device 22 is performed compared to the fourth embodiment in which the imaging device 12 performs image processing. Can be done.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described. FIG. 13 shows a configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 13 includes an imaging device 13 and a display device 20. Since the configuration of the display device 20 has already been described, the description thereof is omitted.

  The imaging device 13 includes an imaging module 100, a first operation interface 101, a first communication module 102, a transmission detection unit 103, a first control unit 104d, and a storage module 105. The description of the configuration that has already been described is omitted.

  In the present embodiment, the first control unit 104d includes an information adding unit 1040 and a shooting control unit 1043. Since the information adding unit 1040 has already been described, description thereof is omitted. The shooting control unit 1043 transmits a live image before the first shooting instruction is input via the first operation interface 101 or before the second shooting instruction is received by the first communication module 102. If not, the imaging parameter of the imaging module 100 is controlled. The imaging parameter of the imaging module 100 is a parameter that defines the operation of the imaging module 100. The function of the first control unit 104d may be realized by software.

  When the live image is not transmitted, the display device 20 does not display the live image. If a still image is shot without confirmation of composition or the like using a live image, there is a high possibility that shooting will fail (a still image different from the still image desired by the user will be shot). The shooting control unit 1043 automatically sets the imaging parameters of the imaging module 100 at the time of shooting to predetermined parameters in order to suppress shooting failure when live images are not transmitted. Imaging parameters of the imaging module 100 set by the imaging control unit 1043 may be stored in the storage module 105 in advance. The imaging control unit 1043 controls the imaging module 100 according to the set imaging parameter, and causes the imaging module 100 to generate a still image.

  For example, the shooting control unit 1043 sets the shooting mode to the full auto mode, and automatically sets the shutter speed and aperture parameters according to the shooting scene. Alternatively, the imaging control unit 1043 sets the focus control parameters so that the focus control is performed based on the focus state at the center of the imaging area of the imaging module 100. Alternatively, the imaging control unit 1043 sets exposure control parameters so that exposure control is performed based on the exposure state at the center of the imaging region of the imaging module 100.

  Alternatively, the imaging control unit 1043 starts focus control based on the focus state at the center of the imaging area of the imaging module 100 when the shutter button that is the first operation interface 101 is half-pressed, and imaging is performed. While tracking the subject position starting from the center of the imaging area of the module 100, focus control parameters are set so that focus control is performed based on the subject position.

  Alternatively, the imaging control unit 1043 starts exposure control based on the exposure state at the center of the imaging area of the imaging module 100 when the shutter button that is the first operation interface 101 is half pressed, and imaging is performed. While tracking the subject position starting from the center of the imaging area of the module 100, exposure control parameters are set so that exposure control is performed based on the subject position.

  You may combine said control and the control demonstrated below. For example, the imaging control unit 1043 may set a format, a compression rate (file size), and a recorded image size (number of pixels) when storing a still image in the storage module 105. For example, the imaging control unit 1043 causes the storage module 105 to store a RAW image that is the format of an image output from the imaging module 100 and a compressed image (such as a JPEG image) obtained by performing compression processing on the RAW image. Also good. When these images are stored in the storage module 105, the transmission information generated by the information adding unit 1040 is added to at least one of these images.

  Alternatively, the shooting control unit 1043 may set the state parameter of the imaging device 13 or the display device 20 so as to emit a shutter sound from the imaging device 13 or the display device 20 when shooting a still image. When the imaging control unit 1043 sets the state parameter of the display device 20, the first communication module 102 transmits the state parameter to the display device 20, the second communication module 201 of the display device 20 receives the state parameter, The second control unit 203a controls the state of the display device 20 according to the received state parameter. For example, when the live image is not transmitted, the imaging device 13 emits a shutter sound according to the state parameter of the imaging device 13. Further, when a live image is being transmitted, the display device 20 emits a shutter sound according to the state parameter of the display device 20.

  Alternatively, the shooting control unit 1043 may set the state parameters of the imaging device 13 or the display device 20 so that the imaging device 13 or the display device 20 emits light emitting elements such as LEDs when shooting a still image. . For example, when the live image is not transmitted, the light emitting element of the imaging device 13 emits light according to the state parameter of the imaging device 13. When a live image is being transmitted, the light emitting element of the display device 20 emits light according to the state parameter of the display device 20.

  FIG. 14 shows an example of an operation procedure of the imaging device 13. The operation of the imaging device 13 will be described with reference to FIG. FIG. 14 does not show the generation and transmission of the live image.

  The processing in steps S600 to S608 is similar to the processing in steps S100 to S108 in FIG. If it is determined in step S601 that the live image is not transmitted, the imaging control unit 1043 sets the imaging parameters of the imaging module 100 (step S620). After the imaging parameters are set, the process of step S603 is performed.

  The process of step S620 may be performed after the process of step S603 is performed. Further, after the process of step S607 is performed, the shooting may be forcibly ended without performing the determination of step S608.

  In the present embodiment, when a still image is captured without transmitting a live image, the imaging parameters of the imaging module 100 are automatically set. Therefore, a shooting failure (a still image different from the still image desired by the user) is set. Shooting) can be suppressed.

(Seventh embodiment)
Next, a seventh embodiment of the present invention will be described. FIG. 15 shows a configuration example of the imaging system according to the present embodiment. The imaging system illustrated in FIG. 15 includes an imaging device 14 and a display device 20. Since the configuration of the display device 20 has already been described, the description thereof is omitted.

  The imaging device 14 includes an imaging module 100, a first operation interface 101, a first communication module 102, a transmission detection unit 103, a first control unit 104e, and a storage module 105. The description of the configuration that has already been described is omitted.

  In the present embodiment, the first control unit 104e includes an information addition unit 1040, an image selection unit 1041, an image processing unit 1042, and a display interface detection unit (display IF detection unit) 1044. The display interface detection unit 1044 determines whether or not a display interface (OVF or EVF) that displays an optical image or a live image of a subject that can be attached to and detached from the imaging device 14 is attached to the imaging device 14. To detect. Whether or not the OVF or EVF is attached to the imaging device 14 may be detected by mechanical detection or electrical detection. The information adding unit 1040 has an imaging device whose display interface is before the first imaging instruction is input via the first operation interface 101 or before the second imaging instruction is received by the first communication module 102. 14 is added to the still image generated based on the first shooting instruction or the second shooting instruction. The storage module 105 stores a still image to which transmission information and mounting information are added. The method of adding the mounting information to the still image by the information adding unit 1040 is the same as the method of adding the transmission information to the still image by the information adding unit 1040.

  In the present embodiment, the image selection unit 1041 attaches transmission information indicating that a live image is not transmitted from the still images stored in the storage module 105 and a display interface to the imaging device 14. The still image to which the mounting information indicating that it is attached is added. The image processing unit 1042 performs image processing on the still image selected by the image selection unit 1041. The first communication module 102 transmits the still image processed by the image processing unit 1042 to the display device 20.

  In this embodiment, the display interface detection unit 1044 identifies the type of the display interface when detecting that the display interface is attached to the imaging device 14. The information adding unit 1040 has an imaging device whose display interface is before the first imaging instruction is input via the first operation interface 101 or before the second imaging instruction is received by the first communication module 102. 14 and whether or not the display interface is attached to the imaging device 14 and the display information indicating the type of the display interface is based on the first imaging instruction or the second imaging instruction. It is added to the generated still image. The image processing unit 1042 performs image processing corresponding to the type of the display interface indicated by the mounting information on the still image selected by the image selection unit 1041. The function of the first control unit 104e may be realized by software.

  For example, different signals are output from the OVF or the EVF when the OVF is attached to the imaging device 14 and when the EVF is attached to the imaging device 14. The display interface detection unit 1044 identifies the type of display interface based on the signal output from the OVF or EVF. For example, resistance elements having different resistance values are mounted on each of OVF and EVF, and the display interface detection unit 1044 detects a current output from the resistance element when the same voltage is applied to the resistance element. Identifies the type of display interface.

  Alternatively, a switch that is pressed exclusively according to the type of the display interface is provided in a portion that contacts the display interface in the imaging device 14, and the display interface detection unit 1044 determines the type of the display interface based on the state of the switch. You may identify. For example, when a first switch for OVF and a second switch for EVF are provided on the surface of the imaging device 14 and the OVF is mounted on the imaging device 14, only the first switch is pressed, and the EVF Is mounted on the imaging device 14, only the second switch is pressed.

  FIG. 16 illustrates an example of an operation procedure of the imaging device 14. The operation of the imaging device 14 will be described with reference to FIG. FIG. 16 does not show generation and transmission of live images.

  The processing in steps S700 to S703 is the same as the processing in steps S100 to S103 in FIG. After the transmission information is generated in step S702 or step S703, the display interface detection unit 1044 detects whether or not the display interface is mounted on the imaging device 14, and the display interface is mounted on the imaging device 14. Is detected, the type of display interface is identified (step S704).

  After the display interface is detected, the first control unit 104e determines whether the display interface attached to the imaging device 14 is OVF based on the result of the detection by the display interface detection unit 1044. Is determined (step S705). If it is detected in step S704 that the display interface is attached to the imaging device 14 and it is identified that the display interface type is OVF, the display interface attached to the imaging device 14 is OVF. Otherwise, it is determined that the display interface attached to the imaging device 14 is not OVF.

  When it is determined that the display interface mounted on the imaging device 14 is OVF, the information adding unit 1040 generates mounting information whose value is 0 (step S706). When it is determined that the display interface attached to the imaging device 14 is not OVF, the first control unit 104e is attached to the imaging device 14 based on the detection result of the display interface detection unit 1044. It is determined whether or not the display interface is EVF (step S707). If it is detected in step S704 that the display interface is attached to the imaging device 14 and it is identified that the type of the display interface is EVF, the display interface attached to the imaging device 14 is EVF. Otherwise, it is determined that the display interface attached to the imaging device 14 is not EVF. When it is determined that the display interface attached to the imaging device 14 is not EVF, the display interface is not attached to the imaging device 14 or an unknown display interface that is neither OVF nor EVF is attached.

  When it is determined that the display interface mounted on the imaging device 14 is EVF, the information adding unit 1040 generates mounting information whose value is 1 (step S708). When it is determined that the display interface attached to the imaging device 14 is not EVF, that is, when the display interface is not attached to the imaging device 14, the information adding unit 1040 generates attachment information whose value is 2. (Step S709).

  The mounting information having a value of 0 indicates that the display interface is mounted on the imaging device 14 and the mounted display interface is OVF. The mounting information having a value of 1 indicates that the display interface is mounted on the imaging device 14 and the mounted display interface is EVF. The mounting information having a value of 2 indicates that the display interface is not mounted on the imaging device 14 or that an unknown display interface that is neither OVF nor EVF is mounted on the imaging device 14. The value of the mounting information may be a value that can distinguish the presence / absence of mounting of the display interface and the type of the display interface, and may be other than 0, 1, and 2.

  After the mounting information is generated, the first control unit 104e determines whether an instruction to capture a still image has been issued (step S710). When the first photographing instruction is input via the first operation interface 101 or when the second photographing instruction is received by the first communication module 102, it is determined that the photographing of the still image is instructed. . Further, when the first photographing instruction is not input via the first operation interface 101 and the second photographing instruction is not received by the first communication module 102, the photographing of the still image is instructed. It is determined that it is not.

  If it is determined that shooting of a still image has not been instructed, the process of step S714 is performed. In addition, when it is determined that shooting of a still image has been instructed, the first control unit 104e instructs the imaging module 100 to shoot a still image, and causes the imaging module 100 to perform shooting to generate a still image ( Step S711). As a result, the imaging module 100 performs imaging and generates a still image. The generated still image is output to the first control unit 104e.

  After the still image is generated, the information adding unit 1040 receives the transmission information generated in step S702 or S703 and the mounting information generated in any of steps S706, S708, and S709 in step S711. Is added to the still image generated based on the shooting instruction or the second shooting instruction (step S712). After the transmission information and the mounting information are added to the still image, the first control unit 104e stores the still image to which the transmission information and the mounting information are added in the storage module 105 (step S713). Thereby, the storage module 105 stores the still image to which the transmission information and the mounting information are added.

  After the still image is stored in the storage module 105, the first control unit 104e determines whether or not to end shooting (step S714). When an instruction to end shooting is input via the first operation interface 101, or when a command to end shooting is received by the first communication module 102, it is determined to end shooting. In addition, when an instruction to end shooting is not input via the first operation interface 101 and a command to end shooting is not received by the first communication module 102, it is determined that shooting is not ended. Is done.

  If it is determined that the shooting is to be terminated, the shooting mode process ends. If it is determined not to end shooting, the process of step S700 is performed. After the process in step S713 is performed, the shooting mode process may be forcibly terminated without performing the determination in step S714.

  FIG. 17 illustrates an example of an operation procedure of the imaging device 14 performed after the operation illustrated in FIG. 16 is performed. The operation of the imaging device 14 will be described with reference to FIG.

  The processing in steps S720 to S725 is the same as the processing in steps S200 to S205 in FIG. If it is determined in step S725 that the value of the transmission information is 0, that is, if a live image has not been transmitted when a still image is captured, the first control unit 104e reads from the storage module 105 in step S723. The mounting information added to the read still image is checked (step S726).

  The first control unit 104e determines whether or not the value of the mounting information checked in step S726 is 2 (step S727). When it is determined that the value of the wearing information is 2, that is, when the display interface is not attached to the imaging device 14 when a still image is captured, or an unknown display interface that is neither OVF nor EVF is an imaging device. 14, the image selection unit 1041 selects a still image corresponding to the transmission information having a value of 0 and the mounting information having a value of 2 as a transmission target (step S728). The selected still image is output to the image processing unit 1042.

  After the still image is selected, the image processing unit 1042 performs image processing on the selected still image based on subject information (for example, subject luminance information) (step S729). For example, the image processing unit 1042 adjusts the brightness so that a specific subject (such as a person's face) becomes brighter. Alternatively, the image processing unit 1042 may adjust the brightness so that a portion where halation occurs is darker.

  After the image processing is performed, the image processing unit 1042 performs image processing on the selected still image based on subject information (for example, subject position information or posture information), and is performed in step S729. A process different from the image process is performed (step S732). For example, the image processing unit 1042 trims a portion including a specific subject (such as a human face). Alternatively, the image processing unit 1042 may perform a process of rotating the still image based on the posture information of the subject.

  In step S732, the image processing unit 1042 may perform image processing according to the shooting scene. For example, when the shooting scene is shooting of a landscape, the image processing unit 1042 performs a process of rotating a still image so that a specific subject (horizontal line or the like) has a specific inclination (horizontal with respect to the image). You may go.

  After the image processing is performed, the first control unit 104e causes the first communication module 102 to transmit the still image subjected to the image processing to the display device 20 (step S734). As a result, the first communication module 102 transmits the still image on which image processing has been performed to the display device 20.

  After the still image is transmitted, the process shown in FIG. 17 ends. If it is determined in step S725 that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, a still image corresponding to the transmission information is displayed by the image selection unit 1041. The selected still image is transmitted to the display device 20 in step S734.

  When it is determined in step S727 that the mounting information value is not 2, the first control unit 104e determines whether the mounting information value checked in step S726 is 0 (step S730). When it is determined that the value of the wearing information is 0, that is, when the OVF is attached to the imaging device 14 at the time of capturing a still image, the image selection unit 1041 transmits the transmission information having the value 0 and the value 0. A still image corresponding to certain mounting information is selected as a transmission target (step S731). The selected still image is output to the image processing unit 1042, and image processing is performed in step S732.

  If it is determined in step S730 that the value of the mounting information is not 0, that is, the value of the mounting information is 1, and if the EVF is mounted on the imaging device 14 when a still image is captured, the image selection unit 1041 A still image corresponding to the transmission information whose value is 0 and the mounting information whose value is 1 is selected as a transmission target (step S733). The selected still image is output to the first communication module 102, and is transmitted to the display device 20 by the first communication module 102 in step S734. In any of steps S731 and S733, the image selection unit 1041 adds transmission information indicating that the live image is not transmitted and mounting information indicating that the display interface is mounted on the imaging device 14. Selected still image.

  After the process of step S734 is performed, the process similar to the process of step S208 of FIG. 5 may be performed to repeat the transmission of the still image. If it is determined in step S730 that the value of the mounting information is 1, that is, if the EVF is mounted on the imaging device 14 during still image shooting, image processing different from the image processing performed in step S732 is performed. You may go to a still image. If it is determined in step S725 that the value of the transmission information is 0, that is, if a live image is not transmitted when a still image is captured, the same processing as the image processing performed in step S407 in FIG. Processing may be performed.

  If a command is not received from the display device 20 and a still image transmission instruction is input via the first operation interface 101, the processing from step S723 may be performed. Therefore, the processing of steps S720 to S722 is not essential for this embodiment.

  If it is determined in step S725 that the value of the transmission information is 1, that is, if a live image is being transmitted when a still image is captured, the still image may not be transmitted to the display device 20. Therefore, transmission of a still image generated after transmission of a live image is not essential to this embodiment.

  In the present embodiment, a still image generated after transmission of a live image is performed on a still image generated without transmission of a live image and a display interface mounted on the imaging device 14. And image processing can be performed. Thereby, a still image suitable for photographing using the display interface can be generated.

  In this embodiment, live image transmission is not performed, and image processing corresponding to the type of display interface is performed on a still image generated with the display interface mounted on the imaging device 14. Can do. As a result, a still image suitable for the display interface used can be generated.

The function of the first control unit 104f may be realized by software. In the present embodiment, the imaging device 15 performs the process shown in FIG. 16 when capturing a still image.

  In the present embodiment, the first communication module 102 receives the still image, the transmission information, and the first shooting instruction via the first operation interface 101 or before the first communication module 102 inputs the first shooting instruction. Before receiving the second shooting instruction, the display interface 22 transmits the mounting information indicating whether or not the display interface is mounted on the imaging device 15. The information adding unit 1040 adds the mounting information to the still image generated based on the first shooting instruction or the second shooting instruction. The storage module 105 stores a still image to which transmission information and mounting information are added. The second communication module 201 receives a still image, transmission information, and mounting information from the imaging device 15. The image selection unit 2031 is equipped with transmission information indicating that a live image is not transmitted from the still images received by the second communication module 201 and a display interface attached to the imaging device 15. A still image to which mounting information indicating is added is selected. The image processing unit 2032 performs image processing on the still image selected by the image selection unit 2031.

  In this embodiment, the display interface detection unit 1044 identifies the type of display interface when it is detected that the display interface is attached to the imaging device 15. The information adding unit 1040 has an imaging device whose display interface is before the first imaging instruction is input via the first operation interface 101 or before the second imaging instruction is received by the first communication module 102. 15 and whether or not the display interface is attached to the imaging device 15 and the display information indicating the type of the display interface is based on the first imaging instruction or the second imaging instruction. It is added to the generated still image. The image processing unit 2032 performs image processing corresponding to the type of display interface indicated by the mounting information on the still image selected by the image selection unit 2031.

  FIG. 19 shows an example of the operation procedure of the display device 22. The operation of the display device 22 will be described with reference to FIG.

  When the process is started, the second control unit 203c causes the second communication module 201 to transmit a command requesting transmission of a still image to the imaging device 15 (step S800). As a result, the second communication module 201 transmits a command requesting transmission of a still image to the imaging device 15.

  The command transmitted by the display device 22 is received by the imaging device 15 in step S300 in FIG. In step S <b> 301, the first control unit 104 f causes the first communication module 102 to transmit any of the still images stored in the storage module 105 to the display device 22. As a result, the first communication module 102 transmits one of the still images stored in the storage module 105 to the display device 22.

  When the transmission information and the mounting information are embedded in the still image, the transmission information and the mounting information are also transmitted by transmitting the still image. When the still image is separated from the transmission information and the mounting information and are associated with each other, the imaging device 15 may transmit the still image, the transmission information, and the mounting information at the same time, or the imaging device 15 You may transmit a still image, transmission information, and mounting information sequentially.

  After the command is transmitted in step S800, the second control unit 203c causes the second communication module 201 to receive the still image, the transmission information, and the mounting information transmitted by the imaging device 15 (step S801). ). As a result, the second communication module 201 receives the still image, the transmission information, and the mounting information transmitted by the imaging device 15. The received still image, transmission information, and mounting information are output to the second control unit 203c.

  The processing in steps S802 to S803 is the same as the processing in steps S502 to S503 in FIG. If it is determined in step S803 that the value of the transmission information is 0, that is, if the live image is not transmitted when the still image is captured, the second control unit 203c receives the still image received in step S801. The mounting information added to the image is examined (step S804).

  The second control unit 203c determines whether or not the value of the mounting information checked in step S804 is 2 (step S805). When it is determined that the value of the wearing information is 2, that is, when the display interface is not attached to the imaging device 15 at the time of capturing a still image, or an unknown display interface that is neither OVF nor EVF is an imaging device. 15, the image selection unit 2031 selects a still image corresponding to the transmission information having a value of 0 and the mounting information having a value of 2 as a display target (step S806). The selected still image is output to the image processing unit 2032.

  After the still image is selected, the image processing unit 2032 performs image processing on the selected still image based on subject information (for example, subject luminance information) (step S807). For example, the image processing unit 2032 adjusts the brightness so that a specific subject (such as a person's face) becomes brighter. Alternatively, the image processing unit 2032 may adjust the brightness so that a portion where halation occurs is darker.

  After the image processing is performed, the image processing unit 2032 performs image processing on the selected still image based on subject information (for example, subject position information or posture information), and is performed in step S807. A process different from the image process is performed (step S810). For example, the image processing unit 2032 trims a part including a specific subject (such as a human face). Alternatively, the image processing unit 2032 may perform processing for rotating the still image based on the posture information of the subject.

  In step S810, the image processing unit 2032 may perform image processing according to the shooting scene. For example, when the shooting scene is shooting of a landscape, the image processing unit 2032 performs a process of rotating a still image so that a specific subject (horizontal line or the like) has a specific inclination (horizontal with respect to the image). You may go.

  After the image processing is performed, the second control unit 203c displays the still image on which the image processing has been performed on the image display interface 202 (step S812). As a result, the image display interface 202 displays a still image on which image processing has been performed.

  After the still image is displayed, the process shown in FIG. 19 ends. If it is determined in step S803 that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, a still image corresponding to the transmission information is displayed by the image selection unit 2031. In step S812, a still image is transmitted to the display device 20.

  When it is determined in step S805 that the value of the mounting information is not 2, the second control unit 203c determines whether or not the value of the mounting information checked in step S804 is 0 (step S808). When it is determined that the value of the wearing information is 0, that is, when the OVF is attached to the imaging device 15 at the time of shooting a still image, the image selection unit 2031 has the transmission information having the value 0 and the value 0. A still image corresponding to certain mounting information is selected as a display target (step S809). The selected still image is output to the image processing unit 2032 and image processing is performed in step S810.

  If it is determined in step S808 that the value of the mounting information is not 0, that is, the value of the mounting information is 1, and the EVF is mounted on the imaging device 15 at the time of shooting a still image, the image selection unit 2031 A still image corresponding to transmission information whose value is 0 and mounting information whose value is 1 is selected as a display target (step S811). The selected still image is output to the image display interface 202, and is displayed by the image display interface 202 in step S812. In both steps S809 and S811, the image selection unit 2031 adds transmission information indicating that the live image is not transmitted and mounting information indicating that the display interface is mounted on the imaging device 15. Selected still image.

If it is determined in step S808 that the value of the mounting information is 1, that is, if the EVF is mounted on the imaging device 15 during still image shooting, image processing different from the image processing performed in step S810 is performed. You may go to a still image. If it is determined in step S803 that the value of the transmission information is 0, that is, if no live image is transmitted when a still image is captured, the same processing as the image processing performed in step S505 in FIG. Processing may be performed.

  The display device 22 may not transmit a command requesting transmission of a still image. For example, when a still image transmission instruction is input via the first operation interface 101, the imaging device 15 may transmit the still image and transmission information to the display device 22. Therefore, the process of step S800 is not essential for this embodiment.

  If it is determined in step S803 that the value of the transmission information is 1, that is, if a live image is transmitted when a still image is captured, the still image may not be displayed. Therefore, display of a still image generated after transmission of a live image is not essential to this embodiment.
