Description

Technical Field

[0001] The present invention relates to an electronic device, and more particularly, to a technique of setting a part of an area of a captured video as a cropping area and transmitting a video corresponding to the cropping area. Background Art

[0002] In a system for video transmission, for example, one or more electronic devices are connected to a switcher. In response to an instruction from a user, a video output from the switcher (a video to be transmitted) is appropriately switched among a plurality of videos input to the switcher. In the switcher, a video output from the switcher as a broadcast video (PGM output video) and a video expected to be output as a broadcast video subsequently (next output video) are set. The switcher sends a tally signal corresponding to the PGM output video to the electronic device that outputs the PGM output video, and sends a tally signal corresponding to the next output video to the electronic device that outputs the next output video.

[0003] When receiving a tally signal sent from the switcher, the electronic device turns on a tally light. For example, when receiving a tally signal corresponding to the PGM output video, the electronic device turns on the tally light in red. When receiving a tally signal corresponding to the next output video, the electronic device turns on the tally light in green. Thus, a user of the electronic device can determine whether the video output from the electronic device is the PGM output video, the next output video, or neither the PGM output video nor the next output video.

[0004] A cropping function of setting a part of an area of a captured video as a cropping area and outputting a video corresponding to the cropping area to the outside is known. The position and size of the cropping area can be changed in response to an instruction (operation) from a user. By displaying a frame indicating the cropping area superimposed on a video corresponding to the entire area of the captured video (entire video), the user can determine the cropping area and can also confirm an area other than the cropping area.

[0005] An electronic device (one electronic device) can use the cropping function to simultaneously output a plurality of videos corresponding to a plurality of areas respectively. Thus, the number of electronic devices in the system can be reduced.

[0024] <First Embodiment>

[0025] Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.

[0026] In the first embodiment, a plurality of regions in the captured video are set as a plurality of cropping regions. The video corresponding to the entire region of the captured video is referred to as the "entire video", and the video corresponding to the cropping region is referred to as the "cropped video". The video output from an external device such as a switcher is referred to as the "PGM output video", and the video to be output from the external device subsequently is referred to as the "next output video".

[0027] In the first embodiment, a digital video camera 10 (hereinafter described as "camera 10") that receives a cue signal from an external device will be described. When the camera 10 outputs a plurality of videos corresponding to a plurality of regions respectively, the camera 10 enables a user to determine, for example, which one of the plurality of videos is the PGM output video.

[0028] Figure 1 It is a block diagram illustrating the configuration of the camera 10.

[0029] The imaging lens 106 is a lens group including a zoom lens and a focusing lens. The zoom lens is a lens for changing the zoom ratio by changing the focal length. The zoom lens is controlled by the zoom control unit 102. The focusing lens is a lens for performing focusing. The focusing lens is controlled by the distance measurement control unit 103.

[0030] The imaging unit 104 is an imaging element (image sensor) including a CCD or CMOS element etc. that converts an optical image into an electrical signal. The A / D converter 105 converts the analog signal output from the imaging unit 104 into a digital signal. The shutter 101 covers the imaging system of the camera 10 (the part including the imaging lens 106 etc.) to prevent contamination and damage of the imaging system.

[0031] The image processing unit 107 performs predetermined image processing (e.g., resizing processing such as pixel interpolation and reduction, or color conversion processing, etc.) on the image data from the A / D converter 105 or the image data from the memory control unit 108. The image processing unit 107 uses the captured image data to perform predetermined calculation processing, and the system control unit 50 performs exposure control and distance measurement control based on the calculation results obtained by the image processing unit 107. Thus, automatic focusing (AF) processing, automatic exposure (AE) processing, and flash pre-emission (EF) processing of the through-the-lens (TTL) method are performed. The image processing unit 107 also uses the captured image data to perform predetermined calculation processing, and performs TTL automatic white balance (AWB) processing based on the obtained calculation results.

[0032] The image data from the A / D converter 105 is written to the memory 109 via the image processing unit 107 and the memory control unit 108 or via the memory control unit 108. In the memory 109, for example, the image data obtained by the imaging unit 104 and converted into digital data by the A / D converter 105 is stored for various processes. The memory 109 has a storage capacity sufficient to store a predetermined number of still images, moving images for a predetermined time, and sounds. The memory 109 also serves as a memory (video memory) for image display. The image data to be displayed on the display unit 110 is also stored in the memory 109. The display unit 110 displays, for example, the image data obtained by the imaging unit 104 and converted into digital data by the A / D converter 105, and the image data read from the recording medium 122, etc. A frame indicating a cropping area and on-screen display (OSD) data such as an OSD prompt for notifying the reception of a prompt signal can be displayed on the display unit 110.

[0033] The D / A converter 123 converts the image data for display stored in the memory 109 into an analog signal, and supplies the converted analog signal to the display unit 110. Therefore, the image data for display written to the memory 109 is displayed by the display unit 110 via the D / A converter 123. The display unit 110 is a display such as a liquid crystal display (LCD), and performs display according to the analog signal from the D / A converter 123. The digital signal A / D-converted by the A / D converter 105 and accumulated in the memory 109 is converted into an analog signal by the D / A converter 123, and sequentially transmitted to the display unit 110 for display. Thus, a live view image is displayed, and the function as an electronic viewfinder is realized. The display unit 110 can be an organic electroluminescence (EL) display, etc.

[0034] The video output unit 126 reads the image data accumulated in the memory 109 via the memory control unit 108, converts the image data into a video signal, and outputs the converted video signal to the outside. In the first embodiment, the video output unit 126 includes a Serial Digital Interface (SDI) terminal and a High-Definition Multimedia Interface (HDMI, which is a registered trademark) terminal. The video output unit 126 converts the format of the video into a format compatible with the SDI terminal and outputs the video from the SDI terminal, or converts the format of the video into a format compatible with the HDMI terminal and outputs the video from the HDMI terminal. The number of terminals is not particularly limited. The video output unit 126 can also extract (cut out and crop) a cropping area from the image and output the image data of the cropping area.

[0035] The non-volatile memory 111 is an electrically erasable / recordable memory and is, for example, an EEPROM. The non-volatile memory 111 stores constants, programs, etc. for the operation of the system control unit 50. The program is a program for executing various flowcharts described below.

[0036] The system control unit 50 controls the entire camera 10. The system control unit 50 implements the various processes described below by executing the programs stored in the non-volatile memory 111. The system control unit 50 also performs display control by controlling the memory 109, the D / A converter 123, the display unit 110, etc.

[0037] The system memory 113 is, for example, a RAM. The system memory 113 stores constants, variables for the operation of the system control unit 50, and programs read from the non-volatile memory 111, etc. The system timer 114 is a time measurement unit that measures the time for various controls and the time of the embedded clock.

[0038] The operation unit 115 is used to input various operation instructions (various instructions from the user) to the system control unit 50. The system control unit 50 performs various processes in response to the instructions input from the user via the operation unit 115. The operation unit 115 includes various buttons such as a menu button, a cancel button, four-direction keys (up, down, left, and right keys), a SET (set) key, and an AF / MF key, etc. For example, when the menu button is pressed, a menu screen for performing various settings is displayed on the display unit 110. The user can intuitively perform various settings by using the menu screen, four-direction keys, and set key displayed on the display unit 110. The user can set one or more cropping areas for the image data stored in the memory 109, and can also separately change the position and size of one or more cropping areas. The user can also switch the area of the video output from the video output unit 126.

[0039] The touch panel 116 is a touch sensor that detects various touch operations on the display surface of the display unit 110 (the operation surface of the touch panel 116). The touch panel 116 and the display unit 110 may be integrated. For example, the touch panel 116 is configured such that the transmission of light does not interfere with the display of the display unit 110, and is attached to the upper layer of the display surface of the display unit 110. Then, the input coordinates on the touch panel 116 are associated with the display coordinates on the display surface of the display unit 110. Thereby, a graphical user interface (GUI) can be provided as if the user can directly operate the screen displayed on the display unit 110.

[0040] The mode changeover switch 117 changes the operation mode of the system control unit 50 to one of a moving image recording mode, a reproduction mode, and the like.

[0041] The power switch 118 is a push button for turning on and off the power of the camera 10.

[0042] The grip zoom 112 is a seesaw push button. The system control unit 50 detects the amount of depression (operation amount) of the grip zoom 112 when the grip zoom 112 is depressed from the reference position, and changes the zoom magnification at a zoom speed corresponding to the detected amount of depression. The system control unit 50 changes the zoom magnification by changing the position of the imaging lens 106 (zoom lens) via the zoom control unit 102. In the first embodiment, it is assumed that as the amount of depression of the grip zoom 112 increases, the output voltage of the grip zoom 112 is changed by a relatively large amount. Thereby, the system control unit 50 can detect the amount of depression of the grip zoom 112 by detecting the output voltage of the grip zoom 112.

[0043] The power control unit 119 includes a battery detection circuit, a DC-DC converter, a switching circuit for switching the blocks to be energized, and the like, and detects whether a battery is installed, the type of the battery, and the remaining battery level. The power control unit 119 controls the DC-DC converter based on the detection result and the instruction of the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 122 during a necessary period. The power supply unit 120 includes primary batteries such as alkaline batteries and lithium batteries, secondary batteries such as NiCd batteries, NiMH batteries, and Li batteries, and an AC adapter.

[0044] The recording medium I / F 121 is an interface with a recording medium 122 such as a memory card and a hard disk. The recording medium 122 is a recording medium for recording the captured image data, and includes a semiconductor memory and a magnetic disk.

[0045] The prompt signal receiving unit 124 receives a prompt signal from the outside via the communication unit 127. In the first embodiment, the prompt signal corresponds to (indicates) one of a plurality of states of the output video (the video output from the video output unit 126), such as the PGM output video or the next output video, etc. The prompt signal receiving unit 124 may receive the same number of prompt signals as the number of terminals included in the video output unit 126. When the video output unit 126 outputs a plurality of output videos (for example, a plurality of output videos corresponding to a plurality of cropping regions respectively), the prompt signal receiving unit 124 receives a prompt signal for at least one of the plurality of output videos. The prompt signal corresponding to the output video may also be considered as the prompt signal corresponding to the cropping region and the prompt signal corresponding to the terminal of the video output unit 126. In the first embodiment, it is assumed that the prompt signal receiving unit 124 receives a prompt signal from an external device such as a switcher via the communication unit 127. There is no particular limitation on the external device that outputs the prompt signal and the method of receiving the prompt signal, as long as it is possible to determine the terminal (output video) and the state corresponding to the prompt signal.

[0046] The camera setting transceiver unit 128 transmits and receives the setting information of the camera 10 to and from the outside via the communication unit 127. Therefore, various settings can be made without using the operation unit 115.

[0047] The communication unit 127 communicates with the outside. In the first embodiment, it is assumed that the communication unit 127 performs wired communication with an external device connected to the camera 10 via a cable. The communication unit 127 may also perform wireless communication via an antenna.

[0048] The prompt notification unit 125 transmits the prompt signal received by the prompt signal receiving unit 124. For example, the prompt notification unit 125 outputs the prompt signal to an external device. When the external device is a prompt light (LED light), the prompt notification unit 125 turns on the prompt light by outputting the prompt signal to the prompt light. For example, when only the prompt signal corresponding to the PGM output video is received, the prompt notification unit 125 outputs the prompt signal to the prompt light so that the prompt light turns on in red. When only the prompt signal corresponding to the next output video is received, the prompt notification unit 125 outputs the prompt signal to the prompt light so that the prompt light turns on in green. When the prompt signal corresponding to the PGM output video and the prompt signal corresponding to the next output video are received, the prompt notification unit 125 turns on the prompt light in red by only outputting the prompt signal corresponding to the PGM output video (specific state) to the prompt light. The external device is not limited to the prompt light. Instead of the external device, the prompt light can be part of the camera 10. The prompt notification unit 125 can turn on the terminal (output video) and status corresponding to the received prompt signal in an identifiable manner.

[0049] Figure 2 is a flowchart illustrating the processing of the camera 10. Figure 2 The processing of is implemented by the system control unit 50 by loading the program stored in the non-volatile memory 111 into the system memory 113 and executing the program. Figure 2 The processing of, for example, is performed at the display update timing of the display unit 110 after the camera 10 is powered on by a user operating the power switch 118. When the refresh rate of the display unit 110 is 60 Hz, the processing of is performed 60 times per second. Figure 2 The processing of.

[0050] In S201, the system control unit 50 acquires the captured video (input video) from the imaging unit 104 (specifically, the A / D converter 105) or the recording medium 122, etc., and displays the captured video (entire video) on the display unit 110. It is possible to display an area including all the cropped areas, and it is possible to display a partial area of the captured video (input video or entire video).

[0051] In S202, the system control unit 50 displays a frame (item) indicating a cropping area on the display unit 110. For example, the system control unit 50 sets a plurality of cropping areas for the captured video in response to an instruction from the user. Then, the system control unit 50 displays a plurality of frames (a plurality of items) indicating the plurality of cropping areas on the display unit 110 such that the plurality of frames are superimposed on the captured video (the entire video). Thus, a display video is displayed on the display unit 110, which is a video based on the captured video (the entire video) and is a video capable of identifying a plurality of cropping areas. The method for enabling the identification of the cropping area is not particularly limited. For example, the cropping area can be identified by coloring the cropping area.

[0052] In S203, the system control unit 50 determines whether the video output from the SDI terminal (SDI output video) is a cropped video. When the SDI output video is a cropped video, the process proceeds to S204. Otherwise (when the SDI output video is the entire video or the video is not output from the SDI terminal), the process proceeds to S208.

[0053] In S204, the system control unit 50 determines (confirms) a cue signal corresponding to the SDI terminal (SDI output video). When a cue signal corresponding to the PGM output video (a cue signal indicating that the SDI output video is the PGM output video) is received, the process proceeds to S205. When a cue signal corresponding to the next output video (a cue signal indicating that the SDI output video is the next output video) is received, the process proceeds to S206. When no cue signal corresponding to the SDI terminal (SDI output video) is received, the process proceeds to S207.

[0054] In S205, the system control unit 50 displays a red OSD cue (a predetermined item) within the cropping area corresponding to the SDI output video. For example, the system control unit 50 displays a red OSD cue inscribed in the frame within the cropping area corresponding to the SDI output video.

[0055] In S206, the system control unit 50 displays a green OSD cue (a predetermined item) within the cropping area corresponding to the SDI output video. For example, the system control unit 50 displays a green OSD cue inscribed in the frame within the cropping area corresponding to the SDI output video.

[0056] In S207, the system control unit 50 hides the OSD cue within the cropping area corresponding to the SDI output video.

[0057] In S208, the system control unit 50 determines whether the video output from the HDMI terminal (HDMI output video) is a cropped video. When the HDMI output video is a cropped video, the process proceeds to S209. When the HDMI output video is not a cropped video (when the HDMI output video is the entire video or when the video is not output from the HDMI terminal), Figure 2 the processing in Figure 2 ends.

[0058] In S209, the system control unit 50 determines (confirms) the cue signal corresponding to the HDMI terminal (HDMI output video). When the cue signal corresponding to the PGM output video (the cue signal indicating that the HDMI output video is the PGM output video) is received, the process proceeds to S210. When the cue signal corresponding to the next output video (the cue signal indicating that the HDMI output video is the next output video) is received, the process proceeds to S211. When the cue signal corresponding to the HDMI terminal (HDMI output video) is not received, the process proceeds to S212.

[0059] In S210, the system control unit 50 displays a red OSD cue (predetermined item) within the cropped area corresponding to the HDMI output video. For example, the system control unit 50 displays a red OSD cue within the box inscribed in the cropped area corresponding to the HDMI output video.

[0060] In S211, the system control unit 50 displays a green OSD cue (predetermined item) within the cropped area corresponding to the HDMI output video. For example, the system control unit 50 displays a green OSD cue within the box inscribed in the cropped area corresponding to the HDMI output video.

[0061] In S212, the system control unit 50 hides the OSD cue within the cropped area corresponding to the HDMI output video.

[0062] Figure 3 is a diagram illustrating an example of a display video. In Figure 3 , a yellow box 301 indicating the area (cropped area) of the SDI output video and a green box 302 indicating the area (cropped area) of the HDMI output video are displayed such that these boxes are superimposed on the captured video 300. Three or more cropped areas can be set, and three or more boxes can be displayed. In Figure 3Among them, the SDI output video is selected as the PGM output video, and the HDMI output video is selected as the subsequent output video. Therefore, the red OSD prompt 303 inscribed in the yellow box 301 indicating the SDI output video area is displayed, and the green OSD prompt 304 inscribed in the green box 302 indicating the HDMI output video area is displayed. There are no special restrictions on the colors of the boxes and the OSD prompts.

[0063] As described above, according to the first embodiment, it is possible to identify in the displayed video which area among the multiple areas in the input video the received prompt signal corresponds to. Therefore, when the electronic device outputs multiple videos corresponding to multiple areas respectively, the user can determine which of the multiple videos is the PGM output video.

[0064] The video output unit 126 may be able to output two or more output videos corresponding to the same area. When two or more output videos corresponding to one area are output, multiple prompt signals corresponding to that one area can be received. For example, a prompt signal corresponding to the PGM output video and a prompt signal corresponding to the subsequent output video can be received as prompt signals corresponding to one area. In this case, the system control unit 50 can display an item indicating all states corresponding to the multiple prompt signals of that one area in association with that one area. In Figure 4 In A of, for the cropped area indicated by the box 400, a prompt signal corresponding to the PGM output video and a prompt signal corresponding to the subsequent output video are received. Therefore, the red OSD prompt 401 and the green OSD prompt 402 are inscribed in the box 400 and displayed. The area of the box 400 is not only the SDI output video area but also the HDMI output video area.

[0065] When multiple prompt signals corresponding to one area are received and one of the multiple prompt signals corresponds to the PGM output video (a specific state), the system control unit 50 can display only the item indicating the PGM output video in association with that one area. In Figure 4 In B of, for the cropped area indicated by the box 400, a prompt signal corresponding to the PGM output video and a prompt signal corresponding to the subsequent output video are received. Therefore, only the red OSD prompt 403 inscribed in the box 400 is displayed. The area of the box 400 is not only the SDI output video area but also the HDMI output video area.

[0066] In the first embodiment, the OSD prompt is displayed within the cropped area, but the system control unit 50 can display the OSD prompt around the cropped area that receives the prompt signal. For example, the system control unit 50 can display an OSD prompt for a frame circumscribing the cropped area that receives the prompt signal. In Figure 4 In C of Figure 4 , the SDI output video is selected as the PGM output video, and the HDMI output video is selected as the next output video. Accordingly, a red OSD prompt 404 is displayed inside the frame 301 indicating the SDI output video area, and a green OSD prompt 405 is displayed inside the frame 302 indicating the HDMI output video area.

[0067] The system control unit 50 can display the boundary line of the frame surrounding the area that receives the prompt signal as an OSD prompt. In Figure 4 In D of Figure 4 , the SDI output video is selected as the PGM output video, and the HDMI output video is selected as the next output video. Accordingly, the frame 301 indicating the SDI output video area is surrounded by a red OSD prompt 406 (boundary line), and the frame 302 indicating the HDMI output video area is surrounded by a green OSD prompt 405 (boundary line).

[0068] In response to the reception of the prompt signal, the system control unit 50 can change the recognition mode (recognition method) of one of the cropped area that receives the prompt signal and the cropped area that does not receive the prompt signal. For example, in response to the reception of the prompt signal, the system control unit 50 changes the mode of one of the frame of the cropped area that receives the prompt signal and the frame of the cropped area that does not receive the prompt signal. In Figure 4 In E of Figure 4 , the SDI output video is selected as the PGM output video, and the HDMI output video is selected as the next output video. Accordingly, the frame indicating the HDMI output video area changes from the frame 302 to a frame 408 that has lower prominence (salience) compared to the frame 301 indicating the SDI output video area. Prominence can be regarded as the degree of prominence or visibility. The system control unit 50 can enhance the prominence of the frame indicating the PGM output video area by emphasizing it. In this case, the system control unit 50 may not reduce the prominence of the frame indicating the next output video area.

[0069] The system control unit 50 can display a string indicating the cropped area that receives the prompt signal at a position that does not overlap multiple cropped areas. When displaying various items such as a string at a position that does not overlap multiple cropped areas, it is possible to suppress a reduction in the visibility of the cropped area caused by the item. In Figure 4In F, the OSD 409 (item) is displayed. The OSD 409 includes a string indicating a cropped area box that has received a cue signal. The string of the OSD 409 indicates that a cue signal corresponding to the PGM output video has been received for the yellow box 301, and a cue signal corresponding to the next output video has been received for the green box 302. In Figure 4 In G, the OSD 410 (item) is displayed. The OSD 410 includes a string indicating a terminal (a terminal of the video output unit 126) that has received a cue signal. The string of the OSD 410 indicates that a cue signal corresponding to the PGM output video has been received for the SDI terminal, and a cue signal corresponding to the next output video has been received for the HDMI terminal.

[0070] In the first embodiment, the cue signal is received through communication with the outside, but the method of receiving the cue signal is not limited to this. For example, the cue signal may be received by at least one of a plurality of input terminals corresponding to the respective terminals of the video output unit 126. The input terminal is, for example, a contact input terminal that receives a binary voltage of on or off from the outside. When only the cue signal corresponding to the PGM output video is received, one input terminal may be provided for each terminal of the video output unit 126. When two input terminals are provided for each terminal of the video output unit 126, the cue signal corresponding to the PGM output video and the cue signal corresponding to the next output video can be received in an identifiable manner. One of the two input terminals corresponding to one terminal of the video output unit 126 is the input terminal that receives the cue signal corresponding to the PGM output video, and the other input terminal of the two input terminals is the input terminal that receives the cue signal corresponding to the next output video.

[0071] When one input terminal (first input terminal) is provided for each terminal of the video output unit 126, one input terminal (second input terminal) unrelated to the video output unit 126 may also be provided. By using the plurality of first input terminals to receive the cue signal, it can be identified which terminal among the plurality of terminals of the video output unit 126 the received cue signal corresponds to. When a cue signal corresponding to a specific state (PGM output video or next output video) is received, the second input terminal receives a predetermined signal. Thus, compared with the configuration in which two input terminals are provided for each terminal of the video output unit 126, it can be determined whether the cue signal corresponding to the specific state is received through fewer input terminals.

[0072] <Second Embodiment>

[0073] In the following, a second embodiment of the present invention will be described with reference to the accompanying drawings. In the following, the same description as that of the first embodiment (for example, the description of the configuration and processing that are the same as those of the first embodiment) will be omitted, and the differences from the first embodiment will be described.

[0074] In the second embodiment, the controller 5000 of the camera (the first external device) will be described. The controller 5000 receives a cue signal corresponding to the video output from the camera to the second external device from an external device (the second external device) such as a switcher. When the camera outputs a plurality of videos corresponding to a plurality of regions respectively, the controller 5000 enables the user to determine which video among the plurality of videos is the PGM output video. The controller 5000 may output the video to an external device such as a switcher instead of outputting the video from the camera to an external device such as a switcher.

[0075] Figure 5 is a block diagram illustrating an example of the configuration of the controller 5000. In Figure 5 are the same components as those of the first embodiment ( Figure 1 ) are labeled with the same reference numerals as those in the drawings of the first embodiment.

[0076] The video input unit 5001 receives a video signal from the outside. In the second embodiment, it is assumed that the camera has two SDI terminals and one HDMI terminal, the video input unit 5001 has SDI terminals, and the SDI terminals of the video input unit 5001 are connected to the SDI terminals of the camera. It is assumed that the video input unit 5001 receives (acquires) the entire video from the camera.

[0077] The image processing unit 5002 performs predetermined image processing (such as size adjustment processing such as pixel interpolation and reduction or color conversion processing, etc.) on the image data from the video input unit 5001 or the image data from the memory control unit 5003.

[0078] The image data from the video input unit 5001 is written to the memory 109 via the image processing unit 5002 and the memory control unit 5003 or via the memory control unit 5003.

[0079] The operation unit 5007 is used to input various operation instructions (various instructions from the user) to the system control unit 50. The system control unit 50 performs various processes in response to the instructions input from the user via the operation unit 5007. The operation unit 5007 includes various buttons, such as a menu button, a cancel button, four-direction keys (up, down, left, and right keys), and a setting key. For example, when the menu button is pressed, a menu screen enabling various settings is displayed on the display unit 110. The user can intuitively perform various settings by using the menu screen, four-direction keys, and setting key displayed on the display unit 110. The user can set one or more cropping regions for the image data stored in the memory 109, and can also individually change the position and size of one or more cropping regions. The set position and size of the cropping region are sent from the camera setting transceiver unit 5006, which will be described below, to the camera. The present invention is not limited to the position and size of the cropping region, and various settings related to the camera can be performed by sending and receiving the setting information of the camera.

[0080] The grip zoom 5008 is a rocking push button. The system control unit 50 detects the pressing amount (operation amount) of the grip zoom 5008 when the grip zoom 5008 is pressed from the reference position, and changes the zoom magnification of the camera at a zoom speed corresponding to the detected pressing amount. The system control unit 50 changes the zoom magnification of the camera by sending setting information from the camera setting transceiver unit 5006 to the camera. In the second embodiment, it is assumed that as the pressing amount of the grip zoom 5008 increases, the output voltage of the grip zoom 5008 is changed by a relatively large amount. Therefore, the system control unit 50 can detect the pressing amount of the grip zoom 5008 by detecting the output voltage of the grip zoom 5008.

[0081] The power control unit 5004 includes a battery detection circuit, a DC-DC converter, a switching circuit for switching the blocks to be powered on, etc., and detects whether a battery is installed, the type of the battery, and the remaining battery level.

[0082] The cue signal receiving unit 5005 receives a cue signal from the outside via the communication unit 127. In the second embodiment, the cue signal corresponds to (indicates one of) one of the multiple states of the output video of the camera, such as the PGM output video or the next output video, etc. The cue signal receiving unit 5005 can receive the same number of cue signals as the output video of the camera. In the second embodiment, it is assumed that the cue signal receiving unit 5005 receives a cue signal from an external device such as a switcher via the communication unit 127. The external device that outputs the cue signal and the method of receiving the cue signal are not particularly limited as long as it is possible to determine the output video and state corresponding to the cue signal.

[0083] The camera setting transceiver unit 5006 transmits or receives camera setting information via the communication unit 127. For example, the position and size of the cropping area, selection information of the video output from the camera, the zoom speed of the camera, and setting information regarding AF can be transmitted and received.

[0084] Figure 6 It is a flowchart illustrating the processing of the example controller 5000. Figure 6 The processing of... is implemented by the system control unit 50 by expanding the program stored in the non-volatile memory 111 in the system memory 113 and executing the program. For example, after the controller 5000 is powered on by a user operating the power switch 118, the processing of... is performed at the display update timing of the display unit 110. Figure 6 When the refresh rate of the display unit 110 is 60 Hz, the processing of... is performed 60 times per second. Figure 6 The processing of...

[0085] In S601, the system control unit 50 uses the video input unit 5001 to acquire the captured video (overall video) from the camera, and displays the captured video (overall video) on the display unit 110. The area including all the cropping areas can be displayed, and a partial area of the captured video (entire video) can be displayed.

[0086] In S602, the system control unit 50 uses the camera setting transceiver unit 5006 to receive (acquire) the setting information regarding the cropping area from the camera. The setting information of the cropping area indicates, for example, the position and size of the cropping area.

[0087] In S603, the system control unit 50 displays a frame (item) indicating the cropping area on the display unit 110 based on the setting information acquired in S602. Thereby, a display video is displayed on the display unit 110, which is a video based on the captured video (entire video) and is a video capable of identifying multiple cropping areas.

[0088] In S604, the system control unit 50 uses the camera setting transceiver unit 5006 to receive (acquire) the setting information regarding the video output from the SDI terminal of the camera (SDI output video). The setting information regarding the SDI output video indicates whether the SDI output video is a cropped video, and when the SDI output video is a cropped video, it indicates the cropping area or frame corresponding to the SDI output video.

[0089] In S605, the system control unit 50 determines whether the video output from the SDI terminal of the camera (SDI output video) is a cropped video. When the SDI output video is a cropped video, the process proceeds to S606. When the SDI output video is not a cropped video (when the SDI output video is the entire video or the video is not output from the SDI terminal), the process proceeds to S610.

[0090] In S606, the system control unit 50 determines (verifies) the cue signal corresponding to the SDI terminal of the camera (SDI output video). When the cue signal corresponding to the PGM output video (the cue signal indicating that the SDI output video is the PGM output video) is received, the process proceeds to S607. When the cue signal corresponding to the next output video (the cue signal indicating that the SDI output video is the next output video) is received, the process proceeds to S608. When the cue signal corresponding to the SDI terminal (SDI output video) is not received, the process proceeds to S609.

[0091] S607 to S609 are the same as S205 to S207 of the first embodiment ( Figure 2 ).

[0092] In S610, the system control unit 50 uses the camera setting transceiver unit 5006 to receive (acquire) the setting information about the video output from the HDMI terminal of the camera (HDMI output video). The setting information about the HDMI output video indicates whether the HDMI output video is a cropped video. When the HDMI output video is a cropped video, the setting information indicates the cropping area or frame corresponding to the HDMI output video.

[0093] In S611, the system control unit 50 determines whether the video output from the HDMI terminal of the camera (HDMI output video) is a cropped video. When the HDMI output video is a cropped video, the process proceeds to S612. Otherwise (when the HDMI output video is the entire video or the video is not output from the HDMI terminal), Figure 6 the process ends.

[0094] In S612, the system control unit 50 determines (verifies) the cue signal corresponding to the HDMI terminal (HDMI output video). When the cue signal corresponding to the PGM output video (the cue signal indicating that the HDMI output video is the PGM output video) is received, the process proceeds to S613. When the cue signal corresponding to the next output video (the cue signal indicating that the HDMI output video is the next output video) is received, the process proceeds to S614. When the cue signal corresponding to the HDMI terminal (HDMI output video) is not received, the process proceeds to S615.

[0095] S613 to S615 are the same as S210 to S212 in the first embodiment ( Figure 2 ).

[0096] Figure 7 is a diagram illustrating an example of a display video. In Figure 7 , a yellow frame 701 indicating the area (cropping area) of the SDI output video of the camera and a green frame 702 indicating the area (cropping area) of the HDMI output video of the camera are displayed such that these frames are superimposed on the captured video 700 obtained from the camera. Three or more cropping areas can be set, and three or more frames can be displayed. In Figure 7 , the SDI output video is selected as the PGM output video, and the HDMI output video is selected as the next output video. Accordingly, a red OSD prompt 703 inscribed in the yellow frame 701 indicating the area of the SDI output video is displayed, and a green OSD prompt 704 inscribed in the green frame 702 indicating the area of the HDMI output video is displayed. The color of the frame and the color of the OSD prompt are not particularly limited.

[0097] As described above, according to the second embodiment, when the electronic device outputs a plurality of videos corresponding to a plurality of regions respectively through the processing of the controller, the user can determine which video among the plurality of videos is the PGM output video.

[0098] In the second embodiment, the controller displays a cropping frame to be superimposed on the captured video (entire video) based on the setting information of the cropping frame, but the present disclosure is not limited thereto. For example, the camera can generate a combined video in which the cropping frame is superimposed on the captured video, and the controller can obtain and display the combined video from the camera, and display the OSD prompt superimposed on the combined video. In the second embodiment, the controller receives a prompt signal from the switcher, but the present invention is not limited thereto. The camera can transmit the prompt signal to the controller. In this way, the camera and the controller can appropriately share the processing.

[0099] The above-described various types of control described as being performed by the system control unit 50 can be performed by at least one hardware (e.g., at least one processor and / or at least one circuit). One hardware can control the entire device, or a plurality of hardwares can share the processing to control the entire device.
