Description

[Technical field]

[0001] The present invention relates to an imaging device, a control method for an imaging device, and a program. [Background technology]

[0002] In recent years, some imaging devices, such as video cameras, used on location have an image switching function called a return function, which not only displays images captured by the device's own camera, but also images captured by other cameras as return images and displays them on a display device.

[0003] On the other hand, video cameras may display an OSD (On Screen Display) on a display device by superimposing it on the captured image to inform the user of the recording status of the captured image. The OSD indicating the recording status is often displayed so that it is easily recognizable to the user, in order to prevent the user from continuing to shoot even though recording of the captured image has not yet started. Patent Document 1 proposes a technology for controlling the display position of the OSD depending on the display device in order to prevent the OSD from becoming invisible. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2011-130160 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when switching between the images displayed as shot images and the return images, information about the imaging device is not usually displayed when the return images are displayed, so the OSD indicating the recording status of the imaging device is not displayed in the return images. Also, if the OSD indicating the recording status used when displaying the shot images is superimposed on the return images, the user may mistakenly believe that the return images are being recorded instead of the shot images.

[0006] The present invention has been made in consideration of the problems described above, and aims to provide an imaging device that displays the status of the imaging device so that the user can easily recognize it when displaying captured image or return image. [Means for solving the problem]

[0007] In order to achieve the above object, an imaging device according to the present invention comprises: The imaging device has an imaging unit that captures video and an input unit that inputs return video, and further has a control means that controls a display unit to display either the captured video captured by the imaging unit or the return video input to the input unit, and the control means controls the state of the imaging device to be displayed in different display formats depending on whether the video to be displayed on the display unit is the captured video or the return video. Effect of the Invention

[0008] According to the present invention, it is possible to provide an imaging device that displays the state of the imaging device so that the user can easily recognize it when a captured image or a return image is displayed. [Brief description of the drawings]

[0010] <First embodiment> Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0011] 1 is a diagram showing an example of the schematic configuration of an imaging device according to this embodiment. The imaging device 100 has a CPU 101, a memory 102, a non-volatile memory 103, an image processing unit 104, a display 105, an operation unit 106, a recording medium I / F 108, an external I / F 110, and an imaging unit 113, which are all connected to an internal bus 130. The units connected to the internal bus 130 are configured to be able to exchange data with each other via the internal bus 130.

[0012] The memory 102 is, for example, a RAM (a volatile memory using a semiconductor element, etc.). The non-volatile memory 103 stores image data, audio data, other data, various programs for the operation of the CPU 101, etc. The non-volatile memory 103 is, for example, a hard disk (HD) or a ROM. The CPU 101 performs various processes and controls each part of the imaging device 100 according to the programs stored in the non-volatile memory 103, for example, using the memory 102 as a work memory.

[0013] The image processing unit 104 performs various image processing on image data stored in the non-volatile memory 103 or the recording medium 109, image data captured by the imaging unit 113, etc., under the control of the CPU 101. The image processing performed by the image processing unit 104 includes A / D conversion processing, D / A conversion processing, image data encoding processing, compression processing, decoding processing, enlargement / reduction processing (resizing), noise reduction processing, color conversion processing, etc. The image processing unit 104 may be configured with a dedicated circuit block for performing specific image processing. Also, depending on the type of image processing, the CPU 101 can perform image processing according to a program without using the image processing unit 104.

[0014] The display 105 is a display unit that displays an image and an OSD such as display items superimposed on the image under the control of the CPU 101. In the configuration of FIG. 1, the display 105 is a display device built into the imaging device 100, but may be an external display device (external monitor, television, etc.). When the display 105 is an external display device, the imaging device 100 itself is provided with only an interface for outputting a video signal to be displayed on the display 105. The CPU 101 generates a display control signal according to a program, and controls each part of the imaging device 100 to generate a video signal to be displayed on the display 105 and output it to the display 105. As a result, the display 105 displays an image based on the output video signal.

[0015] The operation unit 106 is an input device for receiving user operations, including a character information input device such as a keyboard, a pointing device such as a mouse or a touch panel, a dial, a joystick, a touch sensor, a touch pad, etc. It may also include a record button 114 for switching between starting and stopping recording of the captured image, which will be described later. It may also include a switch button 107 for switching between displaying the return image and the captured image, which will be described later. The touch panel is an input device that is configured in a planar manner by being overlaid on the display 105, and outputs coordinate information according to the position where it is touched. When the operation unit 106 includes a touch panel, the CPU 101 detects a user operation on the touch panel or the state of the touch panel.

[0016] A recording medium 109 such as a memory card, CD, or DVD can be attached to the recording medium I / F 108 , and data is read from and written to the attached recording medium 109 under the control of the CPU 101 .

[0017] The external I / F 110 is a communication interface with an external device, and has a connector for connecting a cable. For example, it is provided with a USB interface for connecting a personal computer, an RJ45 connector for receiving tally information from an external device, and a connector corresponding to SDI (Serial Digital Interface) or HDMI (registered trademark) (High-Definition Multimedia Interface) for connecting an external monitor. In addition, it is an interface for inputting and outputting video signals, audio signals, and control signals between an external extension unit described later and the extension unit. Of these, the external input unit 111 is a terminal for inputting video data from an external device, such as an SDI terminal or an HDMI terminal. The external output unit 112 is a terminal for externally outputting video data, such as an SDI terminal or an HDMI terminal. Video captured by another imaging device, particularly video being used for recording and broadcasting (distribution), is input to the external input unit 111 as return video. Hereinafter, a video image captured by the imaging unit 113 will be referred to as a captured video image, and a video image input from the outside to the imaging device 100 via the external input unit 111 will be referred to as a return video image. A video image captured by the imaging device 100 and output to the outside via the external output unit 112 may also be input as a return video image, but a video image captured by the imaging device 100 and input to the imaging device 100 via the external input unit 111 will be referred to as a return video image. The imaging unit 113 is a camera unit that includes an imaging element such as a CCD sensor or a CMOS sensor, a zoom lens, a focus lens, a shutter, an aperture, a distance measuring unit, an A / D converter, an ND filter, and the like. The imaging unit 113 can capture still images and videos, and image data of the captured images is transmitted to the image processing unit 104 and is subjected to encoding processing. When recording of the captured video is started by the record button 114, the captured video is recorded in the recording medium 109 as a still image file or a video file, respectively.

[0018] When the imaging device 100 operates in the shooting mode, first, the CPU 101 displays on the display the captured image captured by the imaging unit 113 and subjected to image processing for display by the image processing unit 104 (displaying a live view image). Then, when the CPU 101 detects an operation on the record button 114, the CPU 101 starts recording the captured image (recording a moving image) by recording the captured image captured by the imaging unit 113 and subjected to image processing by the image processing unit 104 on the recording medium 109 via the recording medium I / F 108. When the CPU 101 detects another operation on the record button 114 during the recording of the captured image, it stops recording the captured image on the recording medium 109. The live view image display continues even during the recording of the captured image.

[0019] Furthermore, imaging device 100 is capable of displaying not only captured video (live view video) but also return video input by external input unit 111 on display 105. When CPU 101 detects an operation on switching button 107 while captured video is being displayed on display 105, it switches display 105 to display the return video. When CPU 101 detects an operation on switching button 107 while displaying return video on display 105, it switches display 105 to display captured video. It is possible to switch between displaying captured video and return video regardless of whether captured video is being recorded or not.

[0020] 2 is a diagram showing a configuration example of an expansion unit 200 that can be connected to the imaging device 100 and enables expansion of the functions of the imaging device 100. In this embodiment, the expansion of the functions of the imaging device 100 includes not only an expansion of functions such as adding functions that the imaging device 100 does not have, but also an expansion of functions such as improving the performance of functions that the imaging device 100 has.

[0021] The expansion unit 200 has a CPU 201, a memory 202, a non-volatile memory 203, an image processing unit 204, an operation unit 205, a recording medium I / F 207, and an external I / F 209, which are connected to an internal bus 230. Each unit connected to the internal bus 230 is configured to be able to exchange data with each other via the internal bus 230. The CPU 201, the memory 202, the non-volatile memory 203, the image processing unit 204, the operation unit 205, the switching button 206, the recording medium I / F 207, the recording medium 208, the external I / F 209, the external input unit 210, and the external output unit 211 have the same configurations and roles as the CPU 101, the memory 102, the non-volatile memory 103, the image processing unit 104, the operation unit 106, the switching button 107, the recording medium I / F 108, the recording medium 109, the external I / F 110, the external input unit 111, and the external output unit 112 in FIG. 1, respectively, and therefore description thereof will be omitted.

[0022] It is possible to connect an extension unit to the extension unit connected to the imaging device 100 via the extension-side external I / F. This allows the imaging device 100 to add not only the function of one extension unit, but also the functions and performance of multiple extension units.

[0023] Fig. 3 is a diagram showing an example of a connection pattern of the imaging device 100 and the expansion unit 200. Fig. 3(A) shows a state of only the imaging device 100. Fig. 3(B) shows a state of the expansion unit 200 connected to the imaging device 100. By connecting the external I / F 110 of the imaging device 100 and the external I / F 209 of the expansion unit 200, it is possible to connect the expansion unit 200 and the imaging device 100.

[0024] The external I / F 207 includes a main body connection external I / F and a video input external I / F. The imaging device 100 can be attached to the main body connection external I / F, and video signals, audio signals, and control signals can be input and output between the imaging device 100 and the main body connection external I / F. An SDI (Serial Digital Interface) can be connected to the video input external I / F, and a video signal can be input as a return video from an external device. Note that a configuration in which a video signal such as an HDMI (High-Definition Multimedia Interface) can be input instead of SDI may also be used.

[0025] In this embodiment, video input via an SDI terminal becomes possible by connecting the extension unit 200 to the imaging device 100. When a button (switch button 107) of the operation unit 106 assigned to a video switching function is pressed, the CPU 101 switches the video displayed on the display 105 from the video captured by the imaging unit 113 to the return video input via the external I / F 209.

[0026] FIG. 4 is a diagram showing an example of a display screen 400 displayed on the display 105. As shown in FIG.

[0027] FIG. 4A shows a display screen in a case where the captured image is not being recorded and the captured image is being displayed. On the display screen 400, a recordable time 402, a recording time code 403, and an ND filter operation state 404 are displayed superimposed on a captured image 401. The recordable time 402 is an OSD of a character string indicating the remaining time that can be recorded on the recording medium 109. The recording time code 403 is an OSD of a character string indicating the recording time code associated with the captured image 401. The ND filter operation state 404 is an OSD of an icon indicating that the amount of light reduction by the ND filter of the imaging unit 113 has been changed. Alternatively, the ND filter operation state 404 may be an OSD indicating the amount of light reduction by the ND filter. In FIG. 4A, the captured image is not being recorded, so an OSD indicating a recording state in which recording is being performed is not displayed. Alternatively, an OSD indicating that the recording of the captured image 401 has been stopped may be displayed.

[0028] Fig. 4(B) is a display screen when a captured image is displayed while being recorded. As in Fig. 4(A), the display screen 400 displays a captured image 401, a recordable time 402, a recording time code 403, and an ND filter operation status 404 superimposed thereon. Furthermore, Fig. 4(B) displays a recording status 405 indicating that the captured image is being recorded. The recording status 405 is an OSD with the character string "REC} indicating that the captured image 401 is being recorded, and this character string is displayed in red. Since the information that recording is being performed is important, it is displayed in red, unlike other OSDs. The recordable time 402, recording status 405, and recording time code 403 are displayed in normal OSD display colors other than red, such as white, black, and gray.

[0029] Fig. 4(C) is a display screen when the captured video is not being recorded and the return video is being displayed. On the screen 400, a return status 407 is displayed superimposed on the return video 406. The return status 407 is an OSD with the character string "RET" indicating that the displayed video is a return video. This character string is displayed in a normal OSD display color such as white, black, or gray other than red. In Fig. 4(C), the captured video is not being recorded, so an OSD indicating that the recording status is being recorded is not displayed. However, without being limited to this, an OSD indicating that the recording of the captured video 401 has stopped may be displayed.

[0030] FIG. 4D shows a display screen in the case where a return video is displayed while a captured video is being recorded. On the display screen 400, a return status 407 and a recording status 408 are displayed superimposed on a return video 406. The recording status 408 is an OSD indicating that a captured video is being recorded, and this OSD includes not only the character string "REC" but also an icon indicating an imaging device. If the character string "REC" is displayed alone, it is difficult to tell whether the displayed return video is being recorded or the captured video is being recorded. Therefore, by displaying an icon indicating an imaging device together with the character string, it is indicated that the captured video of the imaging device 100 is being recorded. In addition, the recording status 408 indicating that recording is being performed is displayed in a normal OSD display color such as white, black, or gray other than red. In this way, by displaying the recording status indicating that recording is being performed in a display form (display format) different from that during the display of the return video, the display makes it easy to recognize that the captured video is being recorded, not the displayed return video. In the above explanation, the display form is changed by changing the display color and adding an icon, but the display size or display position may also be changed, or part of the displayed text may be changed (e.g., from "REC" to "REC in progress").

[0031] 4(E) shows a display screen in a case where the captured image is not being recorded, the display has been switched to the return image display, but there is no input of the return image. Nothing is displayed on the screen 400 (black display). Also, an OSD indicating that there is no input of the return image may be displayed.

[0032] Fig. 4(F) shows a display screen in the case where the captured video is being recorded and the display has been switched to return video but there is no input of return video. On screen 400, a recording status 408 indicating that the captured video is being recorded, similar to Fig. 4(D), is displayed on a black screen.

[0033] Next, the display process in the imaging device 100 will be described with reference to the flowchart of FIG. 5. The process of the flowchart of FIG. 5 is realized by the CPU 101 of the imaging device 100 reading a program stored in the non-volatile memory 103 and executing control and arithmetic processing of each unit based on the program. All of the processes of the flowchart of FIG. 5 may be realized by a hardware configuration, or a part of the processes may be executed by a hardware configuration and the remaining processes may be executed by a software configuration based on a program. In the following, it is assumed that the image displayed on the display 105 is switched between the captured image and the return image by operating the switching button 107 of the imaging device 100, and the return image is input from the external input unit 111. However, in the embodiment of FIG. 3(B), the display of the captured image and the return image may be switched by operating the switching button 206 of the extension unit 200 instead of the switching button 107 of the imaging device 100. The return image may be input from the external input unit 210 of the extension unit 200.

[0034] First, in S501, the CPU 101 displays on the display 105 the captured image captured by the imaging unit 113. After that, the process proceeds to S502. At this time, the recordable time 402, the recording time code 403, and the ND filter operation state 404 are displayed superimposed on the captured image 401, as shown in FIG. 4(A).

[0035] In S502, the CPU 101 determines whether or not the captured image captured by the imaging unit 113 is being recorded. If it is determined that the image is being recorded, the process proceeds to S503, and if it is determined that the image is not being recorded, the process proceeds to S504.

[0036] In S503, the CPU 101 reads out the OSD (405) indicating the recording status during recording for when the captured image is displayed, which is stored in the memory 102, and displays the recording status 405 on the display 105, superimposed on the captured image 401, as shown in Fig. 4B. Then, the process proceeds to S505.

[0037] In S504, the CPU 101 hides the recording status 405 during recording on the display 105. When the recording status 405 during recording is displayed, the display is switched so that the recording status 405 during recording is not displayed as shown in Fig. 4(A), but if it is already hidden, no processing is performed and the process proceeds to the next process, S505.

[0038] In S505, CPU 101 determines whether or not an instruction to switch to display the return video has been input. CPU 101 determines that an instruction to switch to the return video has been input as a result of switching button 107 being operated while the captured video is being displayed. If an instruction to switch to the return video has been input, processing proceeds to S506, thereby switching to the display of the return video. If an instruction to switch to the return video has not been input, processing returns to S501 in order to continue displaying the captured video, and the processing of S501 to S505 is repeated.

[0039] In S506, the CPU 101 determines whether or not a return video has been input to the external input unit 111. If a return video has been input, the process proceeds to S507, and if a return video has not been input, the process proceeds to S508.

[0040] In S507, the CPU 101 displays the return video on the display 105 as shown in Fig. 4(C). At this time, as shown in Fig. 4(C), the return state 407 is displayed superimposed on the return video 406. After that, the CPU 101 advances the process to S509.

[0041] In S508, the CPU 101 performs control so as not to display an image on the display 105, as shown in Fig. 4(E). After that, the CPU 101 advances the process to S509.

[0042] In S509, similarly to S502, the CPU 101 determines whether or not the captured video is being recorded. If it is determined that the captured video is being recorded, the process proceeds to S510, and if it is determined that the captured video is not being recorded, the process proceeds to S511.

[0043] In S510, the CPU 101 reads out the OSD (408) of the recording status during recording for displaying the return video from the non-volatile memory 103, and displays the recording status 408 on the display 105 while superimposing it on the return video 406, as shown in Fig. 4D. After that, the CPU 101 advances the process to S512.

[0044] In S511, the CPU 101 hides the recording status 408 during recording on the display 105. When the recording status 408 during recording is displayed, the display is switched so that the recording status 408 during recording is not displayed as shown in Fig. 4C, but if it is already hidden, no processing is performed and the process proceeds to the next process, S512.

[0045] In S512, CPU 101 determines whether or not an instruction to switch to displaying captured video has been input. CPU 101 determines that an instruction to switch to captured video has been input by operating switching button 107 while displaying return video. If an instruction to switch to captured video has been input, processing proceeds to S501, thereby switching to displaying captured video. If an instruction to switch to captured video has not been input, processing returns to S506 in order to continue displaying the return video, and the processing of S506 to S512 is repeated.

[0046] In the flowchart of FIG. 5, the CPU 101 determines whether or not captured video is being recorded, and when it is determined that recording is being performed, the CPU 101 controls to display the recording status 405 (when the captured video is displayed) or the recording status 408 (when the return video is displayed). However, for example, instead of determining whether or not recording is being performed, the display or non-display of the recording status 405 or 408 during recording may be switched in response to detection of an operation on the record button 114. In that case, in response to detection of pressing of the record button 114 during shooting standby (non-recording), recording of the captured video is started and the recording status 405 or 408 during recording is switched to be displayed. Then, in response to detection of pressing of the record button 114 during recording of the captured video, recording of the captured video is stopped and the recording status 405 or 408 during recording is switched to be hidden. In addition, when displaying the recording status 405 or 408 during recording, the CPU 101 may determine which of the recording statuses 405 or 408 to display in response to whether the video currently being displayed on the display 105 is a captured video or a return video.

[0047] As described above, the imaging device 100 of the present embodiment displays the recording status indicating that recording is in progress in a display format different from that when the captured video is displayed while the return video is being displayed. This makes it easier for the user to recognize that the captured video, not the return video, is being recorded even while the return video is being displayed.

[0048] FIG. 6 is a diagram showing a modified example of the display screen displayed on the display 105. In FIG.

[0049] Fig. 6(A) is an example of a screen when recording of captured video has been started with the record button 114, as in Fig. 4(D), and the switch button 107 has been used to switch to display the return video input via the external I / F 207. An OSD consisting of the return video 406, return status 407, and recording status 408 is displayed on screen 600. The imaging device 100 of this embodiment displays the recording status 408 superimposed on the return video as in Fig. 4(D), but is not limited to this, and the recording status may be displayed in a position different from the return video as in Fig. 6(A). This makes it easier for the user to recognize that the captured video, rather than the return video, is being recorded.

[0050] FIG. 6B is an example of a screen when the amount of light reduction by the ND filter mounted on the imaging unit 113 is changed when the switch button 107 is switched to display the return video inputted by the external I / F 207. The screen 600 displays an OSD consisting of the return video 406, the return state 407, and the ND filter operation state 601. The ND filter operation state 601 is an OSD indicating that the amount of light reduction by the ND filter of the imaging unit 113 has been changed. The imaging device 100 of the present embodiment displays the recording state in different OSDs depending on the video being displayed, but the imaging device state that affects the captured video, such as the operation state of the ND filter or the operation state of the aperture as shown in FIG. 6B, may be displayed in different OSDs. This makes it easier for the user to recognize that the operation state related to the captured video, not the return video, has been changed even while the return video is being displayed.

[0051] <Second embodiment> In the first embodiment, an example was disclosed in which the recording status is displayed with an OSD different from that when the captured video is displayed while the return video is being displayed. In this embodiment, it is assumed that the video being used for recording and broadcasting (distribution) is input as the return video. Then, when a tally is received indicating that the return video is the same as the captured video, an example will be described in which the recording status is displayed with the same OSD as when the captured video is being displayed, even while the return video is being displayed.

[0052] Fig. 7 is a diagram showing an example of a schematic configuration of an imaging device of this embodiment. The imaging device 700 has a CPU 101, a memory 102, a non-volatile memory 103, an image processing unit 104, a display 105, an operation unit 106, a recording medium I / F 108, an external I / F 110, and an imaging unit 113, which are connected to an internal bus 130. Note that the CPU 101, the memory 102, the non-volatile memory 103, the image processing unit 104, the display 105, the operation unit 106, the recording medium I / F 108, the external I / F 110, and the imaging unit 113 have the same configurations and roles as those in Fig. 1, and therefore their description will be omitted.

[0053] The tally input unit 701 is a terminal for inputting tally information from the outside, and is, for example, an RJ45 connector. Note that the information is not limited to this and may be information from a communication interface with other external devices.

[0054] 8 is a diagram showing a configuration example of an expansion unit 800 that can be connected to the imaging device 700 and enables expansion of the functions of the imaging device 700. In this embodiment, the expansion of the functions of the imaging device 700 includes not only an expansion of functions such as adding functions that the imaging device 700 does not have, but also an expansion of functions such as improving the performance of functions that the imaging device 700 has.

[0055] The expansion unit 800 has a CPU 201, a memory 202, a non-volatile memory 203, an image processing unit 204, an operation unit 205, a recording medium I / F 207, and an external I / F 209, which are connected to an internal bus 230. Note that the CPU 201, the memory 202, the non-volatile memory 203, the image processing unit 204, the operation unit 205, the recording medium I / F 207, and the external I / F 209 have the same configurations and roles as those in Fig. 2, and therefore their description will be omitted. Also, the tally input unit 801 has the same configuration and role as the tally input unit 701 in Fig. 7, and therefore its description will be omitted.

[0056] 9 is a diagram showing an example of a connection pattern of the imaging device 700 and the expansion unit 800 in this embodiment. FIG. 9(A) shows a state of only the imaging device 700. FIG. 9(B) shows a state of the expansion unit 800 connected to the imaging device 700. By connecting the external I / F 110 of the imaging device 700 and the external I / F 209 of the expansion unit 800, it is possible to connect the expansion unit 800 and the imaging device 700. In this embodiment, by connecting the expansion unit 800 to the imaging device 700, the CPU 101 can detect a tally received by the tally input unit 701.

[0057] 10 is an example of a screen when a tally is received by the tally input unit 701 or tally input unit 801, recording of captured video is started by the record button 114, and the return video input by the external I / F 207 is switched to display by the switch button 107. On the screen 1000, an OSD consisting of the return video 406, the return status 407, and the recording status 405 is superimposed and displayed.

[0058] Next, the display process of the imaging device 700 in the second embodiment will be described with reference to the flowchart of Fig. 11. The process of the flowchart of Fig. 11 is realized by the CPU 101 of the imaging device 700 reading a program stored in the non-volatile memory 103 and executing control and arithmetic processing of each unit based on the program. Note that the embodiment will be described below using the tally input unit 701 of the imaging device 700 as an example, but there is no problem even if the tally input unit 701 of the imaging device 700 is replaced with the tally input unit 801 of the extension unit 800 in the embodiment of Fig. 8(B). In Fig. 11, the same processes as those in the flowchart of Fig. 5 of the first embodiment are denoted by the same reference numerals and will not be described.

[0059] The processes from S501 to S504 are the same as those of the steps denoted by the same reference numerals in the first embodiment shown in FIG. 5, and therefore the description thereof will be omitted.

[0060] After the process of S503 or S504, the CPU 101 advances the process to S1101.

[0061] In S1101, the CPU 101 determines whether or not a tally signal is received by the tally input unit 701. If a tally signal is received, the process proceeds to S1102, and if a tally signal is not received, the process proceeds to S1103.

[0062] In S1102, CPU 101 superimposes tally information indicating that a tally signal is being received, that is, that the video captured by imaging device 700 is being used for recording and broadcasting (distribution), on the captured video displayed on display 105. The tally information may be displayed by superimposing a red frame around the captured image, or an icon labeled "PGM" or a red square icon. After S1102, the process proceeds to S505.

[0063] In S1103, since the CPU 101 has not received a tally signal, the CPU 101 displays the captured image with the tally information hidden. If the tally information is already hidden, the process may proceed to the next step without performing any particular process. After S1103, the process proceeds to S505.

[0064] The processes from S505 to S509 are the same as those of the steps denoted by the same reference numerals in the first embodiment shown in FIG. 5, and therefore a description thereof will be omitted.

[0065] If it is determined in the process of S509 that the captured video is being recorded, the CPU 101 advances the process to S1104.

[0066] In S1104, similarly to S1101, the CPU 101 determines whether or not a tally signal is received by the tally input unit 701. If a tally signal is received, the process proceeds to S1105, and if a tally signal is not received, the process proceeds to S510.

[0067] In S1105, the CPU 101 displays an OSD 405 indicating a recording status (recording in progress) for use when displaying captured video, superimposed on the return video displayed on the display 105, as shown in Fig. 10. Although there may be some delay due to communication, when a tally signal is received and the return video is being displayed, the currently displayed return video is video captured by the imaging device 700. Therefore, since the currently displayed video (return video = captured video) is being recorded, the recording status 405 is displayed, as in the case of displaying captured video, and the recording status 408 for use when displaying the return video is not displayed. Note that in addition to the recording status 405 indicating that recording is in progress, tally information may also be displayed.

[0068] If it is determined in S1104 that the tally signal is not being received, the CPU 101 executes the process of S510, and then proceeds to the process of S512. In the process of S510, the CPU 101 performs control so as to display the recording status 408 for when the return video is displayed, to display the recording status 408 for when the return video is displayed, and not to display the recording status 405 for when the captured video is displayed.

[0069] If it is determined in the process of S509 that the captured video is not being recorded, the CPU 101 advances the process to S511. Then, after the process of S511, the CPU 101 advances the process to S512.

[0070] While the return video is being displayed, basically, the tally information is not displayed on the display 105 because it is not a tally signal for the video being displayed. However, when the captured video is being recorded in the imaging device 700, the displayed return video becomes the video to be recorded, so a display is made to indicate the recording status for when the captured video is being displayed, as shown in Fig. 10. By purposely displaying the recording status using the same OSD as when the captured video is being displayed, even while the return video is being displayed, the user can easily recognize that the captured video that is substantially the same as the return video is being recorded, rather than a video that is different from the return video.

[0071] Furthermore, the imaging device 700 of the present embodiment detects the input of a tally and determines that the return video and the captured video are the same video, but the present invention is not limited to this and may determine that the return video and the captured video are the same video by video analysis of the return video and the captured video.

[0072] <Third embodiment> In the first embodiment, an example was disclosed in which the recording status is displayed with an OSD different from that when the captured image is displayed while the return image is being displayed, but there are cases in which the OSD is superimposed on the return image and input. In this case, if the display of the recording status overlaps the OSD of the return image, it becomes difficult for the user to recognize the recording status. In this embodiment, an example will be described in which the OSD information superimposed on the return image is analyzed and the recording status is displayed so as not to overlap the OSD of the return image.

[0073] Fig. 12 is a diagram showing an example of a schematic configuration of an imaging device of this embodiment. The imaging device 1200 has a CPU 101, a memory 102, a non-volatile memory 103, an image processing unit 104, a display 105, an operation unit 106, a recording medium I / F 108, an external I / F 110, an imaging unit 113, and an analysis unit 1201, which are connected to an internal bus 130. Note that the CPU 101, the memory 102, the non-volatile memory 103, the image processing unit 104, the display 105, the operation unit 106, the recording medium I / F 108, the external I / F 110, and the imaging unit 113 have the same configurations and roles as those in Fig. 1, and therefore their description will be omitted.

[0074] The analysis unit 1201 analyzes the OSD superimposed on the video data input from the external input unit 111 under the control of the CPU 101. The analysis method is, for example, metadata stored in an SDI signal including data such as that shown in Fig. 13. Note that the analysis is not limited to this, and may be information from a communication interface with other external devices, or the type and position of the OSD may be estimated by analyzing the video itself.

[0075] FIG. 14 is a diagram showing an example of return video 1400 and a screen 1402 displayed on display 105.

[0076] 14A is an example of a return video and an OSD superimposed on the return video. In the return video 1400, a video 1401, a recordable time 402, a recording time code 403, an ND filter operation status 404, and a recording status 405 are displayed.

[0077] 14B is an example of a screen displayed on the display 105 when recording of captured video has been started with the record button 114 and switching has been made with the switch button 107 to display the return video inputted via the external I / F 207. A screen 1402 displays a return video 1400 and an OSD consisting of a return status 407 and a recording status 408. At this time, the CPU 101 refers to the data in FIG. 13 and displays the recording status 408 at a position that does not overlap the OSD superimposed on the return video.

[0078] Next, a control method for displaying an OSD indicating the recording status 408 indicating that recording is in progress when the return video is displayed will be described. In this embodiment, in the process of S510 in the first embodiment, the CPU 101 executes the following process.

[0079] First, CPU 101 analyzes the OSD superimposed on the return video input from external input unit 111 using analysis unit 1201. After that, CPU 101 reads out OSD (408) indicating the recording state during recording for when the return video is displayed. Then, CPU 101 places OSD 408 indicating the recording state during recording for when the return video is displayed in a position that does not overlap with the position of the OSD superimposed on the return video analyzed by analysis unit 1201, and displays it on display 105 superimposed on the return video.

[0080] As described above, the imaging device 1200 of this embodiment analyzes the OSD information superimposed on the return video and displays the recording status so as not to overlap with the OSD of the return video. This makes it possible to prevent the user from having difficulty recognizing the recording status due to the overlapping of the OSD.
