Description

[Technical Field]

[0001] The present invention relates to electronic devices, and more particularly to control when acquiring live view images from multiple cameras and enlarging and displaying the live view images. [Background technology]

[0002] There are applications that allow users to connect to multiple cameras wirelessly and remotely control them. These applications run on remote devices such as smartphones, tablet devices, and personal computers, and are useful when users want to remotely control cameras.

[0003] Such application software may also have a function to acquire live view images (LV images) from multiple cameras, display them on the screen of the remote terminal, and allow the user to select from the displayed LV images to easily switch the camera to be operated. Furthermore, in addition to the LV image for switching cameras, the LV image of the camera to be operated may also be displayed as an LV image for checking image quality such as focus.

[0004] In addition, there is a zoom function that cuts out and zooms in on a portion of the LV image to check the image quality in detail. When this zoom function is used, a guide indicating the zoomed-in area is often displayed. Patent Document 1 discloses a technique for displaying an enlarged image of a portion of the LV image superimposed on a portion of the LV image, and for displaying a frame indicating the zoomed-in area superimposed on the LV image. Patent Document 2 discloses a technique for separately displaying an enlarged image and an LV image superimposed with a frame indicating the zoomed-in area on the same screen. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-338449 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-17121 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the above application that connects to multiple cameras, multiple LV images for camera switching are displayed separately from the LV image for image quality confirmation (the LV image of the camera to be operated), so the area in which the LV image for image quality confirmation can be displayed is limited. Therefore, when the LV image for image quality confirmation is enlarged using the above enlargement function, if a guide indicating the enlargement area is displayed using the techniques disclosed in Patent Documents 1 and 2, the LV image for image quality confirmation becomes smaller, and the visibility of the LV image for image quality confirmation becomes poor. There is also a technique that displays a guide indicating the enlargement area superimposed on part of the LV image for image quality confirmation without reducing the size of the LV image for image quality confirmation, but even in this case, the visibility of the LV image for image quality confirmation becomes poor due to the overlapping of the guide.

[0007] The present invention aims to provide a technology that, when a main image, which is one of a plurality of images, is displayed separately from a plurality of images, can make it possible to distinguish an enlarged area while maintaining the visibility of the enlarged main image. The plurality of images may be, for example, a plurality of LV images for camera switching, and the main image may be, for example, a LV image for checking image quality. [Means for solving the problem]

[0008] The electronic device of the present invention includes an acquisition means for acquiring a plurality of images, a selection means for selecting one of the plurality of images as a main image, and a control means for controlling the display of the screen. The screen to be displayed is a first screen including a first area in which the main image is displayed and a second area in which the multiple images are displayed, and when an image of an enlarged area set for the main image is enlarged and displayed in the first area, the control means controls so that an item indicating the enlarged area is not displayed in the first area, and so that the enlarged area is identifiable in the main image displayed in the second area. [Effects of the Invention]

[0009] According to the present invention, when a main image, which is one of the plurality of images, is displayed separately from the plurality of images, the enlarged area can be made identifiable while maintaining the visibility of the enlarged main image. [Brief explanation of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described.

[0012] (System Configuration) FIG. 1 is a schematic diagram showing an example of the configuration of a system according to this embodiment. In the system of FIG. 1, multiple cameras 100 and a smartphone 200 are connected to be able to communicate with each other. While FIG. 1 shows two cameras 100, the number of cameras 100 is not particularly limited. One camera 100 may be connected to the smartphone 200, or three or more cameras 100 may be connected to the smartphone 200. The communication method (standard) is also not particularly limited. For example, it may be Wi-Fi (registered trademark), Bluetooth (registered trademark), or a manufacturer-specific wireless communication method. Communication between the camera 100 and the smartphone 200 does not have to be wireless communication, and may be wired communication. The communication method in the case of wired communication is also not particularly limited. For example, it may be RS-232C, RS-422A, USB, or Ethernet (registered trademark). Any communication method that allows transmission and reception of video and camera setting values ​​is applicable.

[0013] (Camera configuration) 2A is a block diagram showing an example of the configuration of a camera 100 (video camera), which is an example of a data processing device according to this embodiment. Note that the data processing device is not limited to the camera 100. For example, the data processing device may be an electronic device such as a tablet device or a personal computer.

[0014] The control unit 101 controls each unit of the camera 100 in accordance with input signals and a program described below. Note that instead of the control unit 101 controlling the entire camera 100, the entire camera 100 may be controlled by having multiple pieces of hardware share the processing.

[0015] The image capturing unit 102 converts the subject light imaged by the lens included in the image capturing unit 102 into an electrical signal, performs noise reduction processing, etc., and outputs image data, which is digital data. The captured image data is stored in a buffer memory, and then the control unit 101 performs predetermined processing. and recorded on the recording medium 110.

[0016] The nonvolatile memory 103 is an electrically erasable and recordable nonvolatile memory, and stores programs executed by the control unit 101, which will be described later.

[0017] The work memory 104 is used as a buffer memory for temporarily storing image data captured by the image capturing unit 102, as an image display memory for the display unit 106, as a work area for the control unit 101, and the like.

[0018] The operation unit 105 is used to accept instructions for the camera 100 from the user. The operation unit 105 includes, for example, operation members such as a power button used by the user to turn the power of the camera 100 on / off, a release switch used to instruct shooting, and a playback button used to instruct playback of image data. The operation unit 105 also includes a touch panel formed on the display unit 106. The release switch includes switches SW1 and SW2. When the release switch is pressed halfway, switch SW1 turns ON. This allows instructions to perform shooting preparations such as AF (autofocus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, and EF (pre-flash) processing to be accepted. When the release switch is pressed fully, switch SW2 turns ON. This allows instructions to perform shooting preparations.

[0019] The display unit 106 displays live view images (LV images) that are captured images showing a subject in almost real time, captured (recorded) captured images, characters for interactive operation, etc. The camera 100 does not necessarily have to incorporate the display unit 106. The camera 100 can be connected to an internal or external display unit 106, and it is sufficient that the camera 100 has at least a display control function for controlling the display on the display unit 106.

[0020] The recording medium 110 can store image data output from the imaging unit 102. The recording medium 110 may be detachable from the camera 100, or may be built into the camera 100. The camera 100 only needs to have at least the function of accessing the recording medium 110.

[0021] The connection unit 111 is an interface for connecting to an external device. The camera 100 can exchange data with the external device via the connection unit 111. The connection unit 111 includes, for example, an interface for communicating with the external device via wireless LAN. The control unit 101 controls the connection unit 111 to realize wireless communication with the external device.

[0022] The camera 100 can operate as a slave device in infrastructure mode of wireless LAN communication. When operating as a slave device, it can connect to a nearby access point (hereinafter referred to as AP) and participate in a network formed by the AP. Although the camera 100 is a type of AP, it can also operate as a simple AP (hereinafter referred to as simple AP) with more limited functions. An AP is an example of a relay device. When the camera 100 operates as a simple AP, the camera 100 forms a network by itself. Devices surrounding the camera 100 recognize the camera 100 as an AP and can participate in the network formed by the camera 100. A program for operating the camera 100 in this manner is stored in non-volatile memory 103. Although the camera 100 is a type of AP, it is a simple AP that does not have a gateway function for forwarding data received from a slave device to an Internet provider or the like. Therefore, even if the camera 100 receives data from other devices participating in the network it has formed, it cannot forward the data to a network such as the Internet. Alternatively, the connection unit 1 11 may be a wired communication interface instead of a wireless communication interface.

[0023] As mentioned above, the communication method with the external device is not particularly limited. The connection unit 111 may be an interface for performing wired communication using methods such as RS-232C, RS-422A, USB, or Ethernet (registered trademark).

[0024] (Smartphone configuration) 2(B) is a block diagram showing an example of the configuration of a smartphone 200, which is an example of a control device according to this embodiment. Note that the control device is not limited to the smartphone 200. For example, the control device may be an electronic device such as a digital camera, a portable media player, a tablet device, a personal computer, or a mobile phone.

[0025] The control unit 201 controls each unit of the smartphone 200 in accordance with input signals and a program described below. Note that instead of the control unit 201 controlling the entire smartphone 200, the entire smartphone 200 may be controlled by multiple pieces of hardware sharing the processing.

[0026] The imaging unit 202 converts the subject light imaged by the lens included in the imaging unit 202 into an electrical signal, performs noise reduction processing, etc., and outputs the digital data as image data. The captured image data is stored in a buffer memory, then undergoes predetermined processing by the control unit 201, and is recorded on the recording medium 210.

[0027] The nonvolatile memory 203 is an electrically erasable and recordable nonvolatile memory, and stores an OS (operating system), which is basic software executed by the control unit 201, and various programs. A program for communicating with the camera 100 is also held in the nonvolatile memory 203 and installed as a camera control application. Note that processing by the smartphone 200 is realized by loading the camera control application program. The camera control application has functions for utilizing basic functions of the OS installed in the smartphone 200 (e.g., wireless LAN functions, Bluetooth functions, and functions for calling other applications). The camera control application also has a remote shooting function for remotely controlling the camera 100 from the smartphone 200 to shoot images while viewing LV images obtained from the camera 100 on the smartphone 200. The camera control application also has a remote viewing function for remotely viewing image data stored on a recording medium attached to the camera 100 and receiving the image data. Note that the OS of the smartphone 200 may have the functions described in this embodiment (e.g., the camera control application functions).

[0028] The working memory 204 is used as a buffer memory for temporarily storing image data captured by the imaging unit 202, as an image display memory for the display unit 206, as a working area for the control unit 201, and the like.

[0029] The operation unit 205 is used to receive instructions from the user for the smartphone 200. The operation unit 205 includes, for example, an operation member such as a power button that the user uses to instruct the smartphone 200 to power on / off, and a touch panel formed on the display unit 206.

[0030] The display unit 206 displays images, characters for interactive operations, etc. Note that the smartphone 200 does not necessarily have to have a built-in display unit 206. The smartphone 200 can be connected to an internal or external display unit 206, and it is sufficient that the smartphone 200 has at least a display control function for controlling the display of the display unit 206.

[0031] The recording medium 210 can store image data output from the imaging unit 202, image data received from the camera 100, etc. The recording medium 210 may be detachable from the smartphone 200, or may be built into the smartphone 200. The smartphone 200 only needs to have at least a function to access the recording medium 210.

[0032] The connection unit 211 is an interface for connecting to an external device. The smartphone 200 can exchange data with the external device via the connection unit 211. The connection unit 211 includes, for example, an interface for communicating with the external device via a wireless LAN. The control unit 201 controls the connection unit 211 to realize wireless communication with the external device.

[0033] The smartphone 200 can operate as a slave device in infrastructure mode of wireless LAN communication and can participate in a network formed by surrounding APs. The camera 100 may operate as a simple AP, and the smartphone 200 may participate in the network formed by the camera 100.

[0034] The public network connection unit 212 is an interface used when performing public wireless communication. The smartphone 200 connects to other devices via the public network connection unit 212, enabling data communication with the other devices and telephone calls with users of the other devices. During telephone calls, the control unit 201 acquires audio signals via a microphone 213 and outputs audio signals via a speaker 214. The public network connection unit 212 includes an interface for communication using, for example, 3G, 4G, or 5G. The communication method is not particularly limited and may be, for example, LTE, WiMAX, ADSL, or FTTH. The connection unit 211 and the public network connection unit 212 do not necessarily need to be configured as independent hardware; for example, a single antenna may serve as both the connection unit 211 and the public network connection unit 212.

[0035] In the following description, the smartphone 200 may be described as being the subject of processing, but in reality, the control unit 201 reads and executes programs stored in the nonvolatile memory 203 to realize various processes. Similarly, the camera 100 may be described as being the subject of processing, but in reality, the control unit 101 reads and executes programs stored in the nonvolatile memory 103 to realize various processes.

[0036] (Example of a smartphone screen) 3 to 6 are schematic diagrams showing example screens of a camera control application displayed on display unit 206 of smartphone 200. The camera control application connects to multiple cameras simultaneously and enables operation of each camera. The camera control application also communicates with the cameras to receive LV images and various data from the cameras and display them on display unit 206. Display unit 206 is assumed to be a display unit capable of receiving touch operations, such as a display unit with a touch panel formed thereon.

[0037] 3A and 3B are schematic diagrams showing an example of the main screen and multi-screen of a camera control application. Fig. 3A shows an example of the main screen. In Fig. 3A, the control unit 201 is connected to the camera using the camera control application, receives an LV image and various current settings of the camera from the camera, and displays them on the main screen 301.

[0038] The control unit 201 displays a header section 310 for changing various settings at the top of the main screen 301. For example, the control unit 201 displays a camera connection setting button 311, a multi-view changeover switch 312, a view changeover button 313, an LV display switch 314, an assist setting button 315, and a screen lock switch 316 in the header section 310. The control unit 201 also displays an other setting button 317 in the header section 310.

[0039] The camera connection setting button 311 is a setting button for connecting to or disconnecting from a camera. The view switching button 313 is a setting button for selecting a display mode (view) such as normal display mode, multi-screen display mode, or full-screen display mode for LV images (each display mode will be explained later). The assist setting button 315 is a setting button for selecting an assist function such as enlarged display, marker display, or phosle color display (each of the assist functions will be explained later). The other setting button 317 is a setting button for other settings. When the user touches these setting buttons, the control unit 201 transitions the display screen (the displayed screen) to the setting screen corresponding to the touched setting button.

[0040] The multi-view changeover switch 312 is a changeover switch for switching between enabling and disabling the multi-view. The LV display switch 314 is a changeover switch for switching between enabling and disabling the LV display. The screen lock switch 316 is a changeover switch for switching between enabling and disabling the screen lock. Details of these functions will be described later. When the user touches these changeover switches, the control unit 201 switches between enabling and disabling the function corresponding to the touched changeover switch. In FIG. 3(A), the multi-view changeover switch 312 is in a disabled state, the LV display switch 314 is in a enabled state, and the screen lock switch 316 is in a disabled state. The enabled state of the switch means that the function corresponding to the switch is enabled, and the disabled state of the switch means that the function corresponding to the switch is disabled.

[0041] The control unit 201 also displays an LV area 320 and a sub LV area 330 on the main screen 301. The control unit 201 displays an LV image (main image) acquired from the camera to be operated in the LV area 320, and displays all LV images acquired from the connected cameras in the sub LV area 330. In FIG. 3(A), four cameras (Cameras 1 to 4) are connected, and four LV images 331 to 334 acquired from the four cameras respectively are displayed side by side in the sub LV area 330. When the user touches any of the LV images 331 to 334, the control unit 201 selects the touched LV image as the main image and selects the camera corresponding to the touched LV image as the operation target. In FIG. 3(A), LV image 331 (Camera 1) is selected. The control unit 201 displays a cursor surrounding the LV image 331 to indicate that the LV image 331 is selected. Then, the control unit 201 displays the same LV image as the LV image 331 in the LV area 320.

[0042] The control unit 201 also displays a recording information area 340 and an operation area 350 on the main screen 301. In the recording information area 340, the control unit 201 displays the image recording status of the camera to be operated, and displays a recording start / stop button 341 for instructing the camera to start or stop recording. For example, the recording status may include the remaining media time, time code, and REC (recording) / STBY (standby) status. When the user touches the central recording start / stop button 341, the control unit 201 instructs the camera to be operated to start or stop recording of images. The control unit 201 displays a group of operation buttons in the operation area 350. The current setting values ​​that can be changed by the operation button are displayed on the operation buttons. When the user touches an operation button, the control unit 201 instructs the camera to be operated to change the setting value corresponding to the touched operation button, or transitions the display screen to a setting screen for changing the setting value corresponding to the touched operation button. Furthermore, when the user touches the operation area 350 and performs a slide operation (touch move) to move the touch position, the control unit 201 scrolls the group of operation buttons to display the operation buttons that do not fit in the operation area 350.

[0043] Fig. 3(B) shows an example of a multi-screen. For example, the display of the main screen 301 in Fig. 3(A) During this time, when the user touches the multi-view changeover switch 312, the control unit 201 transitions the display screen from the main screen 301 in Fig. 3(A) to the multi-screen 302 in Fig. 3(B). The multi-screen 302 is a screen for checking the recording status of the connected cameras all at once, and the LV area 320 and operation area 350 are not displayed on the multi-screen 302.

[0044] The control unit 201 displays a header section 310 at the top of the multi-screen 302. In FIG. 3(B), unlike FIG. 3(A), the multi-view selector switch 312 is enabled, indicating that the current display screen is a multi-screen. The control unit 201 displays all LV images acquired from the connected cameras and all recording statuses on the multi-screen 302. In FIG. 3(B), four cameras (Cameras 1 to 4) are connected, and four LV images 361 to 364 acquired from the four cameras respectively are displayed side by side. The arrangement of the LV images 361 to 364 differs from the arrangement of the LV images 331 to 334 in FIG. 3(A), and the LV images 361 to 364 are displayed at a larger size than the LV images 331 to 334. Recording statuses 371 to 374 of the four cameras (Cameras 1 to 4) are displayed below the LV images 361 to 364. Furthermore, the control unit 201 displays a recording start / stop button 341 at the bottom of the multi-screen 302. When the user touches the recording start / stop button 341, the control unit 201 instructs all cameras to start or stop recording images at the same time. Note that while the multi-screen 302 is displayed, it is not possible to select only one camera as the target of operation.

[0045] FIG. 3(C) shows an example of the main screen in a state where the LV display is disabled. For example, when the user touches the LV display switch 314 while the main screen 301 in FIG. 3(A) is displayed, the control unit 201 transitions the display screen from the main screen 301 in FIG. 3(A) to the main screen 303 in FIG. 3(C). The main screen 303 is a screen in which the LV area 320 is hidden. A header section 310 is displayed at the top of the main screen 303. Unlike FIG. 3(A), FIG. 3(C) shows that the LV display switch 314 in the header section 310 is disabled, indicating that the LV area 320 is hidden. The main screen 303 also displays the sub-LV area 330, the recording information area 340, and the operation area 350. As the LV area 320 is hidden, the sub-LV area 330, the recording information area 340, and the operation area 350 have moved up. Furthermore, as the LV area 320 is hidden, the operation area 350 is enlarged and the number of operation buttons displayed in the operation area 350 is increased. In FIG. 3C, since all operation buttons are displayed in the operation area 350, the control unit 201 does not accept a slide operation on the operation area 350.

[0046] FIG. 4 is a schematic diagram showing an example of a screen of a camera control application, illustrating an example of switching of the LV display mode.

[0047] FIG. 4(A) shows an example of a screen in normal display mode. Screen 401 in FIG. 4(A) is the same as main screen 301 in FIG. 3(A), but the display state (display content) of header section 310 differs between FIG. 4(A) and FIG. 3(A). For example, when a user touches view switching button 313 while main screen 301 in FIG. 3(A) is displayed, control unit 201 switches the display state of header section 310 from the state shown in FIG. 3(A) to the state shown in FIG. 4(A). In FIG. 4(A), a normal display button 411, a 2×2 display button 412, a full screen display button 413, and a back button 414 are displayed in header section 310. When a user touches normal display button 411, 2×2 display button 412, or full screen display button 413, control unit 201 switches the display mode to the mode corresponding to the touched button. 4(A), a cursor is displayed surrounding normal display button 411, indicating that the display mode is normal display mode. When the user touches back button 414, control unit 201 returns the display state of header section 310 from the state in FIG. 4(A) to the state in FIG. 3(A).

[0048] FIG. 4(B) shows an example of a screen in 2×2 display mode. For example, when the user touches the 2×2 display button 412 while the screen 401 in FIG. 4(A) is displayed, the control unit 201 transitions the display screen from the screen 401 in FIG. 4(A) to the screen 402 in FIG. 4(B). The 2×2 display mode is a multi-screen display mode that displays the sub-LV area 330 without displaying the LV area 320, and is a display mode that displays four LV images in two rows and two columns. In the 2×2 display mode, the camera to be operated is selected in response to a touch on an LV image in the sub-LV area 330, as in the normal display mode (when the screens 301 and 401 in FIGS. 3(A) and 4(A) are displayed). In FIG. 4(B), a cursor is displayed surrounding the LV image (main image) of the camera to be operated among the four LV images arranged in two rows and two columns. A screen 402 in FIG. 4(B) displays a recorded information area 340 and an operation area 350, similar to the screens 301 and 401 in FIGS. 3(A) and 4(A).

[0049] FIG. 4(C) shows an example of a screen in full-screen display mode. For example, when the user touches the full-screen display button 413 while the screen 401 in FIG. 4(A) is displayed, the control unit 201 transitions the display screen from the screen 401 in FIG. 4(A) to the screen 403 in FIG. 4(C). The full-screen display mode is a display mode in which the LV area 320 (main image) is displayed on the entire screen without displaying the sub-LV area 330, the recorded information area 340, and the operation area 350. In the screen 401 in the normal display mode (FIG. 4(A)), the header section 310 (an operation area in which multiple items for user operation are displayed), the LV area 320, and the sub-LV area 330 are vertically aligned. In contrast, in the full-screen display mode (FIG. 4(C)), a full-screen header section 420 is displayed overlapping a portion of the LV area 320. The full-screen header section 420 is an operation area in which some of the multiple items for user operation are displayed. For example, the control unit 201 displays a reduced display switch button 421 and an assist setting button 422 in the full-screen header section 420, superimposed on the main image displayed in the LV area 320. When the user touches the reduced display switch button 421, the control unit 201 returns the display screen to the screen immediately preceding the full-screen display mode screen 403 (for example, screen 401 in FIG. 4(A) or screen 402 in FIG. 4(B)). The assist setting button 422, like the assist setting button 315, is a setting button for selecting an assist function such as enlarged display, marker display, or phosle color display. Note that a display mode similar to the full-screen display mode may be set in which the LV area 320 is displayed larger than the LV area 320 in FIG. 4(A), although not filling the entire screen.

[0050] FIG. 5 is a schematic diagram showing an example of a screen of the camera control application, showing an example when enlarged display is enabled. The camera control application has an enlargement function that cuts out and enlarges a portion of the LV image (main image) of the camera being operated. With the enlargement function, the control unit 201 expands the main image in the working memory 204, sets a portion of the main image as an enlargement area, cuts out an image of the enlargement area from the main image, and resizes and displays the cut-out image. Using the enlargement function, the user can check the image quality, such as focus, in detail.

[0051] FIG. 5(A) shows an example of a screen when an enlarged display is performed in normal display mode. Screen 501 in FIG. 5(A) is the same as main screen 301 in FIG. 3(A), but the display state (display content) of header section 310 differs between FIG. 5(A) and FIG. 3(A). For example, when the user touches assist setting button 315 while main screen 301 in FIG. 3(A) is displayed, control unit 201 switches the display state of header section 310 from the state in FIG. 3(A) to the state in FIG. 5(A). In FIG. 5(A), a WFM switch 511, a marker switch 512, a MAGN switch 513, a false color switch 514, and a back button 515 are displayed in header section 310.

[0052] When the user touches the WFM switch 511, the control unit 201 enables or disables the display of a waveform monitor image that shows the brightness distribution of the LV image (main image) acquired from the camera being operated. When the user touches the marker switch 512, the control unit 201 enables or disables the marker display. Markers are guide lines for confirming composition, such as a center marker that indicates the center of the image, a horizontal marker that indicates the horizontal direction of the image, and a grid marker that divides the image into multiple horizontally and vertically aligned regions. When the user touches the MAGN switch 513, the control unit 201 enables or disables the enlarged display of the LV image. When the user touches the False Color switch 514, the control unit 201 enables or disables false color display, which colors the LV image (converts each pixel value of the LV image into a pixel value corresponding to the brightness). When the user touches the back button 515, the control unit 201 returns the display state of the header section 310 from the state shown in FIG. 5(A) to the state shown in FIG. 3(A).

[0053] Enlarged display is performed only in the LV area 320. The waveform monitor image may not be displayable on a multi-screen, or may be displayable in a 2×2 display mode in which the LV area 320 is not displayed. Markers may be displayed only in the LV area 320 when the LV area 320 is displayed, or may be displayed on each LV image in a 2×2 display mode in which the LV area 320 is not displayed or in a multi-screen. False color display is performed on the LV area 320, and may also be performed on the main image displayed in the sub-LV area 330. False color display does not have to be performed on other LV images displayed in the sub-LV area 330 or on the multi-screen. By limiting the images on which false color display is performed to the main image, the main image stands out, allowing the user to easily identify the main image.

[0054] In FIG. 5A, the WFM switch 511, the marker switch 512, and the False Color switch 514 are disabled, and the MAGN switch 513 is enabled. When a switch is enabled, the function corresponding to the switch is enabled, and when a switch is disabled, the function corresponding to the switch is disabled. Because markers based on the entire LV image are not very useful when checking the enlarged display, the control unit 201 forcibly disables the marker switch 512 when enabling the MAGN switch 513. Similarly, when enabling the MAGN switch 513, the control unit 201 may forcibly disable the display of the AF frame that indicates the area to be focused. When displaying a multi-screen, the control unit 201 may forcibly disable the WFM switch 511, the MAGN switch 513, and the False Color switch 514. When in 2x2 display mode, the control unit 201 may forcibly disable the MAGN switch 513. When the control unit 201 forcibly puts a switch into the disabled state, the control unit 201 may display the switch in a grayed-out state or the like, so that it is possible to identify that the switch has been forcibly put into the disabled state.

[0055] In FIG. 5A, the control unit 201 enlarges the main image in the LV area 320 and displays a MAGN icon 520, which indicates that the enlarged display is enabled, superimposed on the image. The control unit 201 also makes the enlarged area (the area to be enlarged) identifiable in the main image displayed in the sub LV area 330. The method for making the enlarged area identifiable is not particularly limited. In FIG. 5A, a frame 521 (guide) surrounding the enlarged area and a mask 522 (e.g., a black and translucent mask) covering the area outside the enlarged area are superimposed on the main image displayed in the sub LV area 330. This allows the user to easily identify the enlarged area. Furthermore, by not displaying an item indicating the enlarged area in the LV area 320, it is possible to prevent deterioration in the visibility of the main image displayed in the LV area 320. Note that only one of the frame 521 and the mask 522 may be used.

[0056] In FIG. 5A, the control unit 201 controls the other LV images displayed in the sub LV area 330. When the main image (camera to be operated) is switched, the control unit 201 displays the enlarged area of ​​the main image after the switch in the LV area 320, and continues the enlarged display. This prevents the enlarged display from being frequently switched on and off, and makes user operations less cumbersome.

[0057] The control unit 201 records information about the enlarged area of ​​each LV image (each camera) in the non-volatile memory 203, and uses the information for enlarged display, display of the frame 521 and the mask 522, etc. The default enlarged area is not particularly limited, but for example, the control unit 201 sets an area located in the center of the LV image and having an area of ​​1 / 4 of the entire LV image (the horizontal and vertical sizes are 1 / 2 of the entire LV image) as the enlarged area. In FIG. 5(A), default enlarged areas are set for all of Cameras 1 to 4. If enlarged display is disabled, the control unit 201 does not need to distinguish the enlarged area in the sub-LV area 330.

[0058] FIG. 5(B) shows an example of a screen when the enlargement area is changed from the state shown in FIG. 5(A). When the user performs a slide operation (drag operation) or pinch operation on the LV area 320, the control unit 201 changes the position and size of the enlargement area of ​​the main image. A pinch operation is a touch operation in which two touch positions are touched and moved closer or farther apart. The position of the enlargement area changes in response to a slide operation, the enlargement area is reduced in response to a pinch operation (pinch-in operation) that moves the two touch positions closer together, and the enlargement area is enlarged in response to a pinch operation (pinch-out operation) that moves the two touch positions farther apart. The position of the enlargement area can also be changed by a pinch operation. In the screen 502 of FIG. 5(B), the enlargement area of ​​the main image has changed from that shown in FIG. 5(A), and the display in the LV area 320 and the display of the frame 521 and mask 522 superimposed on the main image in the sub LV area 330 have also changed from those shown in FIG. 5(A). For example, in Fig. 5(A), the body of a dog is displayed in LV area 320, while in Fig. 5(B), the head of a dog is displayed in LV area 320. Also, in Fig. 5(A), frame 521 is displayed in the center of the main image in sub LV area 330, while in Fig. 5(B), frame 521 is displayed in the upper left corner of the main image in sub LV area 330.

[0059] Fig. 5(C) shows an example of a screen when an enlarged display is performed in full-screen display mode. Screen 503 in Fig. 5(C) is the same as screen 403 in Fig. 4(C), but screen 503 in Fig. 5(C) displays a WFM switch 511, a marker switch 512, a MAGN switch 513, and False Color. For example, if the user touches assist setting button 422 while screen 403 in Fig. 4(C) is displayed, control unit 201 displays WFM switch 511, marker switch 512, MAGN switch 513, and False Color. Then, if the user touches assist setting button 422 again, control unit 201 hides WFM switch 511, marker switch 512, MAGN switch 513, and False Color.

[0060] In FIG. 5(C), similar to FIG. 5(A), the WFM switch 511, the marker switch 512, and the false color switch 514 are disabled, and the MAGN switch 513 is enabled. Also, in FIG. 5(C), similar to FIG. 5(A), the control unit 201 enlarges and displays the main image in the LV area 320, and displays a MAGN icon 520 indicating that the enlarged display is enabled, superimposed on the image. In FIG. 5(A), the control unit 201 made the enlarged area identifiable in the sub LV area 330. In FIG. 5(C), the control unit 201 displays an item indicating the enlarged area in the LV area 320. In FIG. 5(C), a reduced image 530 of the main image, in which the enlarged area is made identifiable by a frame 521 and a mask 522, is displayed as an item indicating the enlarged area. Note that the item indicating the enlarged area is not limited to this; for example, it may be a combination of a frame indicating the entire main image and a frame indicating the enlarged area. By displaying the item indicating the enlarged area, the user can easily grasp the enlarged area. In full screen mode, Because the V area 320 is large (occupies the entire screen), even if an item showing the enlarged area is displayed, the visibility of the main image displayed in the LV area 320 is hardly deteriorated.

[0061] Figure 6 is a schematic diagram showing an example of a camera control application screen when marker display is enabled. The camera control application has a marker function that displays markers superimposed on the LV image. The marker function is an assist function for confirming composition. The marker function can display various markers, such as a center marker that indicates the center of the image, a horizontal marker that indicates the horizontal direction of the image, and a grid marker that divides the image into multiple regions aligned horizontally and vertically.

[0062] Fig. 6(A) shows an example of a screen when marker display is performed in normal display mode. Screen 601 in Fig. 6(A) is the same as main screen 301 in Fig. 3(A), but the display state (display content) of header section 310 differs between Fig. 6(A) and Fig. 3(A). In Fig. 6(A), header section 310 displays WFM switch 511, marker switch 512, MAGN switch 513, False Color switch 514, and back button 515. In Fig. 6(A), WFM switch 511, MAGN switch 513, and False Color switch 514 are disabled, and marker switch 512 is enabled.

[0063] 6(A), the control unit 201 displays a marker 610 superimposed on the main image displayed in the LV area 320. Since each LV image displayed in the sub LV area 330 is small and a marker is not very useful, the control unit 201 does not display a marker in the sub LV area 330. As described above, in the case of 2×2 display mode or multi-screen where the LV area 320 is not displayed, each LV image is relatively large, so a marker may be displayed on each LV image.

[0064] FIG. 6(B) shows an example of a marker setting screen. For example, when the user touches the back button 515 and then the other settings button 317 while the screen 501 of FIG. 6(A) is displayed, and instructs the start of marker setting, the control unit 201 transitions the display screen from the screen 601 of FIG. 6(A) to the screen 602 of FIG. 6(B). In the screen 602 of FIG. 6(B), a marker setting menu 620 is displayed superimposed on the screen 601 of FIG. 6(A). The user can display a preferred marker by operating the marker setting menu 620. In FIG. 6(B), the center marker and grid marker are set to be valid, and in FIGS. 6(A) to 6(C), the center marker and grid marker are displayed in the LV area 320.

[0065] Note that, as the marker installation value, the control unit 201 may prepare a plurality of setting values ​​corresponding to a plurality of LV images (a plurality of cameras), respectively, but in this embodiment, a marker setting value common to all LV images (all cameras) is recorded in the nonvolatile memory 203. Therefore, even if the main image (camera to be operated) is switched, the same marker continues to be displayed.

[0066] Fig. 6(C) shows an example of a screen when marker display is performed in full-screen display mode. Screen 603 in Fig. 6(C) is the same as screen 403 in Fig. 4(C), but screen 503 in Fig. 6(C) displays WFM switch 511, marker switch 512, MAGN switch 513, and False Color. In Fig. 6(C), WFM switch 511, MAGN switch 513, and False Color switch 514 are disabled, and marker switch 512 is enabled. Also, in Fig. 6(C), as in Fig. 6(A), control unit 201 displays marker 610 superimposed on the main image displayed in LV area 320.

[0067] (Overall smartphone operation) Fig. 7 is a flowchart showing the overall operation of smartphone 200. The overall operation in Fig. 7 is realized by control unit 201 expanding a program (for example, a camera control application program) recorded in nonvolatile memory 203 into working memory 204 and executing it. For example, when an instruction to start the camera control application is given, the overall operation in Fig. 7 starts.

[0068] In S701, the control unit 201 communicates with the camera 100 via the connection unit 211.

[0069] In S702, the control unit 201 receives data from the camera 100 via the connection unit 211. This data includes the status and capabilities of the camera 100, settings, LV images, and the like.

[0070] In S703, the control unit 201 acquires, from the work memory 204, screen information indicating the type of screen to be displayed on the display unit 206. When the smartphone 200 (camera control application) is started, screen information indicating a main screen (a screen in normal display mode) with LV display (display of the LV area 320) is stored. When the control unit 201 changes the screen in response to a user operation, it updates the screen information recorded in the work memory 204. The screen information indicates, for example, a screen in full screen display mode, a multi-screen, a main screen with LV display, or a main screen without LV display. The screen information may also indicate a screen in 2x2 display mode.

[0071] In S704, the control unit 201 determines whether the display mode is the full-screen display mode (whether the screen information acquired in S703 indicates a screen in the full-screen display mode). If the display mode is the full-screen display mode, the process proceeds to S705; if not, the process proceeds to S714.

[0072] In S705, the control unit 201 displays the full-screen header section 420.

[0073] In S706, the control unit 201 reads information indicating whether the enlargement function (enlarged display) is enabled or disabled from the work memory 204, and determines whether the enlargement function is enabled. If the enlargement function is enabled, the process proceeds to S707, and if not, the process proceeds to S711.

[0074] 7 starts, control unit 201 expands the information on the enlargement area stored in non-volatile memory 203 into working memory 204. In S707, control unit 201 reads out the information on the enlargement area of ​​the main image (LV image of the camera being operated) from working memory 204, cuts out the image of the enlargement area from the main image, and displays it on the entire screen (LV area 320 in FIG. 5(C)). The full-screen header section 420 displayed in S705 is displayed in front of the main image.

[0075] In S708, the control unit 201 displays the reduced image 530 of FIG. 5C (reduced image 530 of the main image) superimposed on the main image displayed in S707.

[0076] In S709, the control unit 201 displays the frame 521 and mask 522 in Fig. 5C superimposed on the reduced image 530 displayed in S708. The frame 521 and mask 522 make the enlarged area identifiable.

[0077] In S710, the control unit 201 displays the MAGN icon 520 in FIG. 5C superimposed on the main image displayed in S707.

[0078] FIG. 5(C) shows the result of enlarging the image in full-screen mode through steps S705 to S710. A screen 503 is displayed.

[0079] In S711, the control unit 201 displays the main image on the entire screen (LV area 320 in FIGS. 4(C) and 6(C)).

[0080] In S712, the control unit 201 determines whether the marker function is enabled by reading information indicating whether the marker function (marker display) is enabled or disabled from the working memory 204. If the marker function is enabled, the process proceeds to S713, and if not, the process proceeds to S730.

[0081] 7, the control unit 201 loads the marker setting values ​​stored in the nonvolatile memory 203 into the working memory 204. In S713, the control unit 201 reads the marker setting values ​​from the working memory 204 and displays the markers superimposed on the main image displayed in S711.

[0082] By performing S705, S706, S711, and S712, the screen 403 in Fig. 4C is displayed when neither enlarged display nor marker display is performed in full screen display mode. By further performing S713, the screen 603 in Fig. 6C is displayed when marker display is performed in full screen display mode.

[0083] In S714, the control unit 201 displays the header section 310.

[0084] In S715, the control unit 201 determines whether or not the screen information acquired in S703 indicates a multi-screen display. If it indicates a multi-screen display, the process proceeds to S716, and if not, the process proceeds to S718.

[0085] In S716, the control unit 201 displays all LV images (LV images 361 to 364 in FIG. 3(B)) acquired from the connected cameras.

[0086] In S717, the control unit 201 displays all the recording states (recording states 371 to 374 in FIG. 3B) acquired from the connected cameras, and the recording start / stop button 341 in FIG. 3B.

[0087] 3B is displayed by steps S714 to S717. When displaying the multi-screen 302, the enlargement function and marker function are ignored, and the multi-screen 302 does not change depending on whether they are enabled or disabled.

[0088] In S718, the control unit 201 determines whether or not the screen information acquired in S703 indicates a main screen with LV display (display of the LV area 320). If it indicates a main screen with LV display, the process proceeds to S719; if not, the process proceeds to S728.

[0089] In S719, the control unit 201 displays the sub LV area 330 of FIGS.

[0090] In S720, the control unit 201 displays the recorded information area 340 and the operation area 350 shown in FIGS.

[0091] In S721, the control unit 201 reads information indicating whether the enlargement function (enlarged display) is enabled or disabled from the work memory 204, and determines whether the enlargement function is enabled. If the enlargement function is enabled, the process proceeds to S722, and if not, the process proceeds to S725.

[0092] In S722, the control unit 201 reads out information about the enlarged area of ​​the main image from the working memory 204, cuts out an image of the enlarged area from the main image, and displays it in the LV area 320 of FIG. 5(A).

[0093] In S723, the control unit 201 displays the frame 521 and mask 522 in FIG. 5A superimposed on each LV image in the sub LV area 330 displayed in S719.

[0094] In S724, the control unit 201 displays the MAGN icon 520 in FIG. 5(A) superimposed on the main image displayed in S722.

[0095] Through steps S714, S715, and S718 to S724, the screen 501 of FIG. 5A is displayed when enlarged display is performed in normal display mode with LV display.

[0096] In S725, the control unit 201 displays the main image in the LV area 320 of FIGS.

[0097] In S726, the control unit 201 determines whether the marker function is enabled by reading information indicating whether the marker function (marker display) is enabled or disabled from the working memory 204. If the marker function is enabled, the process proceeds to S727, and if not, the process proceeds to S730.

[0098] In S727, the control unit 201 reads the marker setting value from the work memory 204 and displays the marker superimposed on the main image displayed in S725.

[0099] Screen 401 in Fig. 4(A) is displayed when neither enlarged display nor marker display is performed in normal display mode with LV display by S714, S715, S718 to S721, S725, and S726. Screen 601 in Fig. 6(A) is displayed when marker display is performed in normal display mode with LV display by further performing S727.

[0100] In S728, the control unit 201 displays the sub LV area 330 of FIG. 3(C).

[0101] In S729, the control unit 201 displays the recorded information area 340 and the operation area 350 in FIG. 3(C).

[0102] 4C in normal display mode without LV display is displayed by steps S714, S715, S718, S728, and S729. When displaying screen 403, the magnification function and marker function are ignored, and screen 403 does not change depending on whether they are enabled or disabled.

[0103] In S730, the control unit 201 determines whether a user operation has been received. If a user operation has been received, the process proceeds to S731; if not, the process proceeds to S702. The user operation is, for example, a touch operation on a touch panel provided on the display unit 206.

[0104] In S731, the control unit 201 determines whether the user operation received in S730 is an operation to end the application. If it is an operation to end the application, the entire operation in Fig. 7 ends, and if not, the process proceeds to S732.

[0105] In S732, the control unit 201 performs processing in accordance with the user operation received in S730, such as changing the display mode or changing the camera setting parameters.

[0106] According to the overall operation described above, on the main screen, the item indicating the enlarged area is the LV area 32. By not displaying 0, it is possible to prevent deterioration in the visibility of the main image displayed in the LV area 320. Furthermore, by displaying an item indicating the enlargement area in the sub LV area 330, the user can easily grasp the enlargement area. Even in full screen display mode, by displaying an item indicating the enlargement area in the LV area 320, the user can easily grasp the enlargement area. In full screen display mode, the LV area 320 is large (taking up the entire screen), so displaying an item indicating the enlargement area does not substantially deteriorate the visibility of the main image displayed in the LV area 320. Markers can be suitably used to check the composition of an LV image displayed at a relatively large size, so they are displayed in the LV area 320 but not in the sub LV area 330.

[0107] Although the 2×2 display mode is omitted from the overall operation in FIG. 7, for example, the 2×2 display mode may be the same as the case where the main screen without LV display is displayed.

[0108] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the present invention are also included in the present invention. Parts of the above-described embodiments may be combined as appropriate.

[0109] For example, in the above-described embodiment, when enlarged display is performed in the LV area 320, the enlarged areas of all LV images are made identifiable in the sub-LV area 330. However, this is not limited to this. When enlarged display is performed in the LV area 320, it may be possible to set whether or not to make the enlarged areas of LV images other than the main image identifiable in the sub-LV area 330.

[0110] Furthermore, in the above-described embodiment, the enlargement area of ​​each LV image (each camera) is set individually, but this is not limited to this. The enlargement areas of other LV images may be changed in conjunction with a change in the enlargement area of ​​the main image. For example, the enlargement areas of each LV image may be set so that the position (relative position) and size (relative size) of the enlargement area relative to the entire LV image are the same between LV images (between cameras). It may also be possible to set whether or not to link the enlargement areas of LV images other than the main image to the main image.

[0111] For example, a setting menu 801 as shown in FIG. 8(A) may be displayed, allowing the user to specify (select) whether or not to make the enlarged area of ​​an LV image that is not the main image identifiable, or whether or not to link the enlarged area of ​​an LV image that is not the main image to the main image.

[0112] The enlarged area of ​​the main image and the enlarged area set for the LV image other than the main image may be distinguished in different ways, for example, by using frames of different colors, brightness, or line types, or by using masks of different colors, brightness, or transparency.

[0113] As shown in FIG. 8B, due to the difference in the aspect ratio between the LV area 320 and the enlarged area of ​​the main image, a margin including an area of ​​a predetermined size (an area in which an item indicating the enlarged area can be displayed) may be generated in the LV area 320. In such a case, an item indicating the enlarged area may be displayed in the margin. In FIG. 8B, a reduced image 802 in which the enlarged area is identifiable by a frame is displayed in the margin. Alternatively, when the main image is a specific image, an item indicating the enlarged area may be displayed in the LV area 320. The specific image is an image in which reduced visibility due to an item indicating the enlarged area is acceptable. For example, the specific image may be an image with low resolution, making it difficult to see details even when enlarged. The specific image may also be an image with few subjects and infrequently enlarged, such as an image of a blue sky. When the enlarged area includes a background including an area of ​​a predetermined size, an item indicating the enlarged area may be displayed on the background.

[0114] Also, although an example in which the present invention is applied to checking LV images from multiple cameras has been described, other For example, the present invention can be applied to a case where multiple videos shot with multiple video cameras are stored in a storage medium and then read out and edited from the storage medium.

[0115] The various controls described above may or may not be performed by a single piece of hardware (e.g., a processor or circuit). The entire device may be controlled by multiple pieces of hardware (e.g., multiple processors, multiple circuits, or a combination of one or more processors and one or more circuits) sharing the processing.

[0116] The above processor is a processor in the broad sense, and includes general-purpose processors and dedicated processors. General-purpose processors include, for example, CPUs (Central Processing Units), MPUs (Micro Processing Units), and DSPs (Digital Signal Processors). Dedicated processors include, for example, GPUs (Graphics Processing Units), ASICs (Application Specific Integrated Circuits), and PLDs (Programmable Logic Devices). Programmable logic devices include, for example, FPGAs (Field Programmable Gate Arrays) and CPLDs (Complex Programmable Logic Devices).

[0117] Although the embodiments of the present invention have been described in detail, the present invention is not limited to these specific embodiments, and various forms within the scope of the gist of the present invention are also included in the present invention. Furthermore, each of the above-described embodiments merely represents one embodiment of the present invention, and each embodiment can be combined as appropriate.

[0118] <Other embodiments> The present invention can also be realized by a process in which a program that realizes one or more functions of the above-described embodiments is supplied to a system or device via a network or a storage medium, and one or more processors in the computer of the system or device read and execute the program, or by a circuit that realizes one or more functions.
