Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an example of the external configuration of a camera 10 as an example of the display control device of the present invention. FIG. 1(a) is a view of the camera 10 viewed from one side, and FIG. 1(b) is a view of the camera 10 viewed from the other side.

The camera 10 has a photographing lens 90 on the front, an operation section 105 on the side, an EVF 103 on the back, and a display section 111 on the top. The EVF 103 and the display unit 111 are detachable (detachable) from the main body of the camera 10 . The video output terminal 110 is a terminal for connecting display means that cannot be removed from the camera 10, such as an HDMI (registered trademark) terminal or an SDI terminal. The operation unit 105 is an operation member having a seesaw type grip zoom 105b (zoom key) and various switches and buttons for receiving various operations from the user. The operation unit 105 includes a controller wheel that is a rotatable operation member, a power switch for switching between power on and power off, a menu button 105a for displaying a menu screen, and a video button for instructing start and stop of shooting. 105c and the like. The mode switch 105d switches the operation mode of the system controller 106 to any one of still image recording mode, moving image shooting mode, playback mode, and the like. The mode changeover switch 105d can be used to directly switch to one of these modes included in the menu screen. Alternatively, after switching to the menu screen once with the mode switching switch 105d, the mode may be switched to one of these modes included in the menu screen using another operation member. Similarly, the movie shooting mode may also include multiple modes.

FIG. 2 is a block diagram showing a configuration example of a camera 10 as an example of the display control device of the present invention.

An imaging unit 101 is an imaging element configured by a CCD, a CMOS element, or the like that converts an optical image into an electric signal. A camera signal processing unit 102 receives a video signal from the imaging device 101 and sends the video signal to the developing unit 103 . The development unit 103 corrects and develops the video signal, and the developed image is stored in the RAM 104 .

The user operation unit 105 receives an operation from the user, and the system controller 106 performs processing according to the user operation. For example, when the pressing of the menu button 105a is detected, a menu screen is displayed on the display unit 111 or the EVF 103, and an item on the menu screen can be selected by a direction instruction operation such as a cross key (not shown). When the user gives an instruction to display a menu screen, item display, or the like, the operation GUI image generation unit 107 generates necessary bitmap data. The generated data is stored in RAM 104 . When the user instructs to display a menu screen or items, the stored video signal and bitmap data are synthesized by the video synthesis processing unit 108 to generate a GUI superimposed video, which is stored in the RAM 104 . When the OSD (On Screen Display) setting is ON, the video composition processing unit 108 displays and outputs a menu screen superimposed on the video.

Whether or not to superimpose a GUI display item on the video output to the video output terminal 110 and the video output to the display unit 111/EVF 103 is set separately according to the user operation unit 105 . The system controller 106 causes the RAM 104 or the ROM 112 to record the superimposition settings respectively set for the video output terminal 110 and the display unit 111/EVF 103 . Based on the recorded settings, the video output terminal 110 and the display unit 111/EVF 103 output video with the GUI display item superimposed when the superimposition setting is set to superimpose, and display the GUI when the setting is not superimposed. Output video without superimposing items. The superimposition setting can be set for each output destination on the menu screen.

Here, the video output terminal 110 is a terminal connected to the camera 10, indicates a general-purpose output terminal such as SDI or HDMI, and is assumed to have one or more terminals. The video output terminal 110 and the video output section 110a are connected, and the video is displayed on the video output section 110a. On the other hand, the display unit 111/EVF 103 may also be used by the user for operations for making settings related to shooting and settings related to display. For example, a user in charge of adjusting the sound volume in shooting etc. sets the sound volume according to a touch operation on the display unit 111 , and a user in charge of instructing the start and end of shooting operates the user operation unit 105 while looking at the EVF 103 . do.

The camera signal processing unit 102 , development unit 103 , operation GUI image generation unit 107 , image composition processing unit 108 , and image output processing 109 are processed according to a program read from the ROM 112 by the system controller 106 .

The recording state detection unit 230 confirms whether or not the user has issued a recording instruction through the user operation unit 105 . The status to be recorded is stored in the RAM 104 by the system controller 106 . If recording is in progress, the image output processing 109 outputs to the video output terminal 110 the video without superimposing the GUI display items, regardless of the superimposition setting for the video output terminal 110 and the operation status of the above-described superimposition display timer. do.

The image output device detection unit 220 detects whether the display unit 111/EVF 103 (detachable image display device) is connected to the camera 10 or not.

Next, the display processing to the video output terminal in this embodiment will be described with reference to FIG. This processing is realized by developing a program recorded in the ROM 112 (nonvolatile memory) in the RAM 104 (system memory) and executing it by the system controller 106 . Note that this processing starts when the power of the camera 10 is turned on and display output to the video output terminal 110 becomes possible.

In S<b>301 , the system controller 106 displays and outputs the image acquired by the image sensor 101 to the image output terminal 110 . In the reproduction mode, an image recorded on a recording medium such as an SD card is acquired and output to the video output terminal 110 for display.

In S302, the system controller 106 determines whether or not an instruction to start or end moving image recording has been issued. If it is determined that an instruction to start or end moving image recording has been issued, the process proceeds to S303; otherwise, the process proceeds to S304.

In S303, the system controller 106 starts or ends recording of moving images.

In S<b>304 , the system controller 106 determines whether or not to turn off the power of the camera 10 . The power of the camera 10 is turned off when the user presses a power (not shown) button included in the operation unit 105 or when the battery runs out. If it is determined that the power of the camera 10 will be turned off, the process of FIG. 3 ends, otherwise the process proceeds to S305.

In S305, the system controller 106 determines whether or not the OSD display setting has been changed on the menu screen. If it is determined that the OSD display settings have been changed, the process proceeds to S306; otherwise, the process proceeds to S307.

At S<b>306 , the system controller 106 changes the OSD display settings and records the settings in the ROM 112 .

In S307, the system controller 106 confirms whether the current OSD display setting for the video output terminal 110 is ON (OSD display ON setting) or OFF (OSD display OFF setting).

In S308, the system controller 106 determines whether or not the OSD display setting confirmed in S307 is ON. If it is determined to be ON, the process proceeds to S309; otherwise, the process proceeds to S310.

In S<b>309 , the system controller 106 turns on the OSD display at the video output terminal 110 . That is, the OSD is superimposed on the video output in S301 and displayed.

In S<b>310 , the system controller 106 determines whether the display unit 111 is currently connected to the camera 10 . If it is determined that the connection is in progress, the process proceeds to S311; otherwise, the process proceeds to S312. The determination in S<b>310 is made based on the detection result of the image output device detection section 220 .

In S311, the system controller 106 determines whether the EVF 103 is currently connected to the camera 10 (whether display is possible on the EVF 103). If it is determined to be connected, the process proceeds to S311; otherwise, the process proceeds to S313. In S310 and S311, even if the display unit 111/EVF 103 is connected to the camera 10, for example, if the image signal cannot be transmitted/received and the output of video or OSD is impossible, No is determined. .

In S<b>312 , the system controller 106 turns off the OSD display to the video output terminal 110 .

In S313, the system controller 106 determines whether or not a flag, which will be described later, is ON. If it is determined that the flag is ON, the process proceeds to S302; otherwise, the process proceeds to S314. The flag determined in S313 indicates that the OSD has been displayed and output to the video output terminal 110 for the predetermined time T since the output destination of the OSD is the video output terminal 110 only. This is because the user may not be aware that the OSD is no longer visible. This is to prevent

In S314, the system controller 106 determines whether or not the timer is counting. The timer determined in S314 is for measuring the time required to display and output the OSD to the video output terminal 110 for a predetermined time T when the OSD display setting is turned off by the user. If it is determined that the timer is counting, the process proceeds to S315; otherwise, the process proceeds to S319.

In S315, the system controller 106 determines whether or not a predetermined time T has passed. The predetermined time T is, for example, 10 seconds or 15 seconds. If it is determined that the predetermined time T has passed, the process proceeds to S316; otherwise, the process proceeds to S323. In this embodiment, even when the user turns off the OSD display, the OSD is displayed in S322, which will be described later, so that the user does not unintentionally lose sight of the OSD. At this time, when the predetermined time T has passed, the OSD that was being displayed is turned off, and the display is performed in accordance with the OSD display settings of the user. If the predetermined time T has elapsed, the user can change the settings midway through if the user is unaware that the OSD will disappear, and if the OSD disappears, the user will be able to change the setting. If the user thinks it is good, the display can be performed as intended by the user. If the display unit 111 and the EVF 103 cannot display and the OSD is not displayed on the video output terminal 110, the menu screen will not be superimposed on the video. Therefore, if the OSD is not displayed unintentionally, the user may find it difficult to display the setting OSD and may take time to perform the operation.

In S<b>316 , the system controller 106 turns on the flag and records it in the RAM 104 .

At S317, the system controller 106 stops the timer.

In S<b>318 , the system controller 106 turns off the OSD display to the video output terminal 110 .

In S<b>319 , the system controller 106 displays an alert indicating that the OSD display will be superimposed on the video and cannot be seen, and a setting change item on the display means of the video output terminal 110 .

In S320, the system controller 106 determines whether the camera 10 is recording moving images. If it is determined that a moving image is being recorded, the process proceeds to S305; otherwise, the process proceeds to S321. If the moving image is being recorded, the OSD is not superimposed on the video in S322. To prevent the visibility of a video being recorded from deteriorating even if a user does not intend that an OSD becomes invisible during video recording.

In S321, the system controller 106 starts the timer mentioned above.

In S322, the system controller 106 turns on the OSD display and outputs to the video output terminal 110 so as to superimpose the OSD.

In S323, the system controller 106 determines whether or not an operation to change the OSD display settings has been performed. S323 determines whether or not the setting change item displayed in S319 has been operated. If the user finds that the display in S319 obscures the OSD, the OSD display setting can be changed to ON. In S323, if an operation is performed to change the OSD display setting, that is, if the OSD display setting is changed from OFF to ON, the process proceeds to S324; otherwise, the process proceeds to S326.

In S<b>324 , the system controller 106 turns on the OSD display setting and records it in the ROM 112 .

In S325, the system controller 106 terminates the timer. The timer may be the system controller 106, or may have a system timer configuration and the system timer may measure the time.

In S<b>326 , the system controller 106 determines whether the display unit 111 or EVF 103 is connected to the camera 10 . If it is determined that the display unit 111 or the EVF 103 is connected to the camera 10, the process proceeds to S317; otherwise, the process proceeds to S313. For example, if the user wants to turn off the display of the OSD on the video output terminal 110 but wants to avoid the OSD being superimposed on the video and not being displayed, another display means should be connected to the camera 10 on the way. you can see the OSD. It should be noted that the determination in S326 and the determinations in S310 and S311 do not need to determine that other display means is physically connected to the camera 10 . For example, if there is display means capable of outputting video or OSD wirelessly or by wire, the determination may be Yes.

It should be noted that the display unit 111 or the EVF 103 was connected when the power was turned on in S301. That is, the determination in S310 or S311 is Yes, and the OSD display is turned off in S312. As a result, the process proceeds to S313, the determination in S313 becomes No, and the display on the OSD is turned ON if the moving image is not being recorded. When the power is turned on in S301, neither the display unit 111 nor the EVF 103 are connected, and the OSD display setting is also OFF. Become. That is, even if the OSD is displayed in S322, the determination in S310 or S311 is Yes, so the OSD display is turned off in S312.

Even if the determination in S310 or S311 is not performed, if the determination in S308 is No, the OSD may be displayed and output to the video output terminal 110 for the predetermined time T.

Alternatively, the OSD may be displayed in S322 regardless of whether the moving image is being recorded without determining whether or not the moving image is being recorded in S320.

The image output device detection unit 220 may periodically check the connection status to the display unit 111 or the EVF 103, or may check each step of S310 or S311. In the case of periodic confirmation, it may be the frame rate cycle, which is the video update cycle, or the cycle in which the panel or EVF updates the video.

Further, when the OSD display setting is OFF, the flag is also ON, and the OSD is not displayed on the display means of the video output terminal 110, and if the moving image is not being recorded, the menu button 105a is pressed again to display the OSD. may be displayed again for a predetermined period of time T. Even when the camera 10 is restarted, the OSD is displayed again because the flag is turned off.

Further, after hiding the OSD, if the display unit 111 and the EVF 103 are not connected, the OSD redisplay item may be superimposed on the video and displayed so that the OSD can be easily redisplayed. good.

It does not matter whether the value of the predetermined time T can be arbitrarily set by the user or it can be set as a system-specific value.

Although it has been described that the OSD is not displayed when it is determined in S320 that the moving image is being recorded, the OSD is displayed and output in S322 in response to completion of the recording of the moving image. may
