It is assumed that the same screen as the screen displayed on the display unit 107 is displayed synchronously on the external display device 200.

  FIG. 4 is a flowchart showing a process of switching from the still image mode (TV mode) to the moving image mode. At the start of the process, a screen 310 shown in FIG. 3A is displayed. In step S401, the CPU 101 determines whether the shooting mode has been changed. Specifically, the CPU 101 compares the shooting mode stored last time, that is, the shooting mode set immediately before with the shooting mode newly set at the processing time, and when both are different, the shooting mode is Determine that it has been changed. If the shooting mode has been changed (YES in S401), the CPU 101 advances the process to S402. If the photographing mode has not been changed (NO in 401), the CPU 101 ends the processing.

  In step S402, the CPU 101 stores a new shooting mode. Next, in step S403, the CPU 101 determines whether the display of the shooting mode guide is valid or invalid. If the display of the shooting mode guide is valid (YES in S403), the CPU 101 advances the process to S404. If the display of the photographing mode guide is invalid (NO in S403), the CPU 101 advances the process to S405. Note that the display of the shooting mode guide is enabled or disabled by the CPU 101. In S404, the CPU 101 displays a screen 340 (FIG. 4D) which is a shooting mode guide screen in the moving image mode. In S405, the CPU 101 displays a screen 330 (FIG. 4C) which is a live view screen for the moving image mode. Thus, the process ends.

  FIG. 5 is a flowchart showing the video data transmission process. In step S501, the CPU 101 determines whether the shooting mode is set and the communication mode is a predetermined communication mode. If the CPU 101 is set to the photographing mode and is in the predetermined communication mode (YES in S501), the process proceeds to S502. The CPU 101 stands by if at least one of the case where the imaging mode is not set and the case where the communication mode is not set is satisfied (NO in S501).

  In step S502, the CPU 101 performs processing for starting live view shooting. In this case, subject light is guided to an imaging element (not shown) included in the imaging unit 104, and imaging data is generated by the imaging element. The imaging data generated by the imaging element is converted into digital data by an A / D converter included in the imaging unit 104, and supplied to the image processing unit 105. The digital data supplied to the image processing unit 105 is subjected to predetermined pixel interpolation processing and color conversion processing by the image processing unit 105. At this time, the pixel interpolation process performed on the digital data by the image processing unit 105 is performed in the imaging device 100 based on the recording setting of the video data set in advance. Note that the recording setting of the video data can be changed by the user using the operation unit 108. Therefore, the user can change the interpolation method performed on the video data to be transmitted to the external display device 200 by changing the recording setting of the video data using the operation unit 108.

  When the recording setting of the video data is set to FHD (Full High Definition), the video data after pixel interpolation processing corresponds to the resolution (1920 × 1080 pixels) of the FHD. Also, when the recording setting of video data is set to SD (Standard Definition), video data after pixel interpolation processing is compatible with SD resolution (maximum 720 x 480 or maximum 720 x 576 pixels) Do.

  Digital data subjected to pixel interpolation processing and color conversion processing by the image processing unit 105 is stored in the memory 102 as video data. In this case, the process of flowchart proceeds from step S202 to step S203. Note that in S202, the imaging unit 104 and the image processing unit 105 may perform an autofocus process, an automatic exposure process, a white balance process, and the like. The image processing unit 105 performs pixel interpolation processing on the digital data according to the recording setting of the video data. Further, the image processing unit 105 may perform image processing other than pixel interpolation processing on digital data according to the analysis result of EDID acquired from the external display device 200.

  Next, in steps S503 to S505, the CPU 101 performs setting processing for transmitting video data to the external display device 200. Specifically, first, in step S503, the CPU 101 determines whether the EDID has been acquired from the external display device 200. The CPU 101 waits until it determines that the EDID has been acquired, and advances the process to S504 when it is determined that the EID has been acquired (YES in S503).

  In S504, the CPU 101 analyzes the EDID acquired from the external display device 200. The analysis result of the EDID analyzed by the CPU 101 is recorded in the memory 102. Next, in step S505, the CPU 101 detects the resolution as the output setting of the video data generated by the imaging unit 104 and the image processing unit 105, and as the output setting set by the external display device 200 from the analysis result of EDID. Detect resolution The imaging unit 104 and the image processing unit 105 generate video data corresponding to the resolution set in the imaging device 100. The resolution set in the photographing apparatus 100 is changed when the user performs an operation for changing the resolution via the operation unit 108. The resolution set by the external display device 200 is a resolution when the external display device 200 displays video data.

  Next, in step S506, the CPU 101 controls the data transmission unit 103a to transmit the video data stored in the memory 102 in the process of step S502 to the external display device 200. In this case, the audio data and the auxiliary data may also be transmitted to the external display device 200 together with the video data. The video data transmitted from the photographing apparatus 100 in the process of S506 is supplied to the external display apparatus 200 and the recording apparatus 300 via the distributor 400. The CPU 101 controls the command processing unit 103 b to transmit a command for notifying transmission of video data to the external display device 200 and the recording device 300 via the CEC line 503 before transmitting video data. Do. The command for notifying to transmit video data is, for example, an <Active Source> message defined in the CEC protocol. Also, the command for notifying that video data is to be transmitted may be a vendor command.

  When transmission of video data is started, the CPU 101 advances the process to step S507. In step S <b> 507, the CPU 101 determines whether an operation for instructing the end of live view shooting has been performed on the operation unit 108. If the CPU 101 determines that the operation for instructing the end of live view shooting has been performed on the operation unit 108 (YES in step S507), the process advances to step S508. If the CPU 101 determines that the operation for instructing the end of live view shooting is not performed on the operation unit 108 (NO in step S507), the process advances to step S506.

  In addition, when the operation for instructing the end of live view imaging is not performed (NO in S507), it is assumed that the setting regarding the resolution of the external display device 200 and the setting regarding the pixels of the external display device 200 are changed. In this case, the imaging device 100 again acquires the EDID from the external display device 200. Thereafter, the CPU 101 performs processing for transmitting video data to the external display device 200 after performing the setting processing of S203.

  In addition, in the case where the operation for instructing the end of live view shooting is not performed (NO in S507), it is assumed that the recording setting of the video data is changed in the photographing apparatus 100. In this case, the photographing apparatus 100 performs the setting process of S503 to S505 again. Furthermore, in this case, the imaging device 100 performs processing for transmitting video data to the external display device 200 after the setting processing of S503 to S505 is performed.

  Further, when the operation for instructing the end of live view shooting is not performed (NO in S507), it is assumed that the video data is transmitted to an apparatus different from the external display apparatus 200. In this case, the imaging device 100 acquires the EDID from a device to which video data is to be transmitted. Thereafter, the CPU 101 performs processing for transmitting video data to the outside after performing setting processing of S503 to S505.

  In step S508, the CPU 101 performs processing for ending live view shooting. In this case, the CPU 101 controls the imaging unit 104 and the image processing unit 105 so as to stop the process of generating video data from the subject. Furthermore, the CPU 101 controls the data transmission unit 103a to stop transmission of video data. Thus, the video data transmission process is completed.

  If the photographing apparatus 100 is a single-lens reflex camera, the CPU 101 causes the light from the subject to be guided to the image pickup element by raising the mirror (not shown) included in the image pickup unit 104 in S502. Further, in step S <b> 508, the CPU 101 prevents the light from the subject from being guided to the imaging device by turning down a mirror (not shown) included in the imaging unit 104.

  FIG. 6 is a flowchart showing the mode switching process. In step S601, the CPU 101 determines whether the mode dial 111 has been operated. When the mode dial 111 is not operated (NO in S601), the CPU 101 stands by, and when the mode dial is operated (YES in S601), the CPU 101 advances the process to S602. In step S602, the CPU 101 determines whether the display of the shooting mode guide is valid or invalid. If the display of the shooting mode guide is valid (YES in S602), the CPU 101 advances the process to S603. If the display of the photographing mode guide is invalid (NO in S602), the CPU 101 advances the process to S605.

  In step S603, the CPU 101 controls to display a shooting mode guide screen (the screen 320 in FIG. 3B or the screen 340 in FIG. 3D). Next, in step S604, the CPU 101 determines whether a shooting mode has been set according to a user operation. The CPU 101 determines that the photographing mode is set when, for example, a user operation set in advance, such as pressing of the decision button or shutter button, is performed. If the photographing mode is not set (NO in S604), the CPU 101 stands by, and if the photographing mode is set (YES in S604), the process proceeds to S605.

  In step S605, the CPU 101 determines whether it is necessary to change the output setting according to the imaging mode set at the time of processing. Specifically, the CPU 101 determines that the change of the output setting is necessary when the output setting of the photographing mode set at the processing time is different from the output setting of the newly set photographing mode.

  A plurality of shooting modes selectable by the mode dial 111 include shooting modes having different resolutions as output settings. In the present embodiment, the resolution is described as an example of the output setting. However, as another example, the output setting may be a frame rate and a dynamic range of a luminance signal such as HDR or SDR.

  If it is determined that the change of the output setting is necessary (YES in S605), the CPU 101 advances the process to S606. If the CPU 101 determines that the output setting does not need to be changed (NO in S605), the process ends. That is, when it is not necessary to change the output setting, the CPU 101 continues the transmission of the video data with the output setting according to the photographing mode set at the processing time. In step S606, the CPU 101 changes the output setting to the output setting of the newly set photographing mode. Next, in step S607, the CPU 101 resumes transmission of video data with the changed output setting. Thus, the mode switching process ends.

  The processing of S605 to S607 is an example of output control processing of a photographed image according to the photographing mode guide. Specifically, when the display of the mode guide is valid when the shooting mode is changed by the rotation of the mode dial, the mode guide is output to the external display device with the output setting corresponding to the shooting mode before the change. It is an example of the processing which controls. In addition, when the display of the mode guide is invalid, this is an example of processing for controlling to output the photographed image to the external display device by changing to the output setting corresponding to the photographing mode changed by the mode dial.

  In step S607, the CPU 101 may control to switch from the output of the shooting mode guide to the output of the captured image in response to the reception of the predetermined operation.

  In addition, the CPU 101 may be able to change the output setting corresponding to the shooting mode. This process is an example of the output setting change process.

  As described above, according to the imaging apparatus 100 according to the embodiment, the change of the output setting is controlled according to whether or not the display of the imaging mode guide is valid. For this reason, since it is not necessary to change the resolution of the external display device 200 before displaying the photographing mode guide, the photographing mode can be smoothly changed. Therefore, the usability when the output setting is changed can be improved.

  Although the preferred embodiments of the present invention have been described above in detail, the present invention is not limited to the specific embodiments, and various modifications may be made within the scope of the present invention as set forth in the claims.・ Change is possible.
