Abstract
Description
Technical Field
[0001] The present invention relates to an electronic device, and particularly relates to control when acquiring live view images from a plurality of cameras and enlarging and displaying the live view images.
Background Art
[0002] There is application software that can wirelessly connect to a plurality of cameras and remotely operate the cameras. Such application software operates on a remote terminal such as a smartphone, tablet device, or personal computer, and is useful when a user wants to remotely operate a camera.
[0003] In addition, such application software may have a function of easily switching the camera to be operated by acquiring live view images (LV images) of a plurality of cameras, displaying them on the screen of the remote terminal, and allowing the user to select the displayed LV images. Further, in addition to the LV image for camera switching, the LV image of the camera to be operated may be displayed as an LV image for checking image quality such as focus.
[0004] In addition, there is an enlargement function of cutting out and enlarging a part of the LV image to check the image quality in detail. When this enlargement function is used, a guide indicating the enlarged area is often displayed. Patent Document 1 discloses a technique of displaying an enlarged image obtained by enlarging a part of the LV image over a part of the LV image and displaying a frame indicating the enlarged area over the LV image. Patent Document 2 discloses a technique of separately displaying an enlarged image and an LV image with a frame indicating the enlarged area overlaid on the same screen.

Patent Document 1
Patent Document 2
[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 being operated), which limits the area in which the LV image for image quality confirmation can be displayed. Therefore, when the above magnification function is used to enlarge the LV image for image quality confirmation, if a guide indicating the magnification area is displayed using the technology 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 deteriorates. There is also a technology that displays the guide indicating the magnification area overlaid on a part of the LV image for image quality confirmation without reducing the size of the LV image for image quality confirmation, but even in that case, the visibility of the LV image for image quality confirmation deteriorates due to the overlap of the guide.
[0007] The present invention aims to provide a technology that enables the identification of an enlarged area while maintaining the visibility of the enlarged main image when displaying a main image, which is one of several images, separately from the multiple images. The multiple images are such as multiple LV images for camera switching, and the main image is such as an LV image for image quality confirmation. [Means for solving the problem]
[0008] The electronic device of the present invention includes an acquisition means for acquiring multiple images, a selection means for selecting one of the multiple images as the main image, and a control means for controlling the display of the screen. The display screen is a first screen including a first area where the main image is displayed and a second area where the plurality of images are displayed, and when the image of the enlarged area set for the main image is enlarged and displayed in the first area, the control means does not display an item indicating the enlarged area in the first area, and controls the main image displayed in the second area so that the enlarged area can be identified. [Effects of the Invention]
[0009] According to the present invention, when displaying a main image, which is one of several images, separately from the other images, it is possible to maintain the visibility of the enlarged main image while making the enlarged area identifiable. [Brief explanation of the drawing]

[Modes for carrying out the invention]
[0011] Embodiments of the present invention will be described below.
[0012] (System Configuration) FIG. 1 is a schematic diagram showing a configuration example of the system according to the present embodiment. In the system of FIG. 1, a plurality of cameras 100 and a smartphone 200 are connected to be communicable with each other. Although two cameras 100 are shown in FIG. 1, the number of cameras 100 is not particularly limited, and one camera 100 may be connected to the smartphone 200, or three or more cameras 100 may be connected to the smartphone 200. Also, the communication method (standard) is not particularly limited, and for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), or a manufacturer's proprietary wireless communication method may be used. The 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 not particularly limited, and for example, RS-232C, RS-422A, USB, or Ethernet (registered trademark) may be used. Any communication method that enables the transmission and reception of video and the transmission and reception of camera setting values is applicable.
[0013] (Configuration of Camera) FIG. 2(A) is a block diagram showing a configuration example of a camera 100 (video camera), which is an example of a data processing device according to the present 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 part of the camera 100 according to the input signal and the program described later. Note that instead of the control unit 101 controlling the entire camera 100, the entire camera 100 may be controlled by a plurality of hardware sharing the processing.
[0015] The imaging unit 102 converts subject light imaged by a lens included in the imaging 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 subjected to predetermined processing by the control unit 101 and recorded on the recording medium 110.
[0016] The non-volatile memory 103 is a non-volatile memory that can be electrically erased and recorded, and stores programs and the like to be executed by the control unit 101, which will be described later.
[0017] The working memory 104 is used as a buffer memory for temporarily holding the image data captured by the imaging unit 102, an image display memory for the display unit 106, a working area of the control unit 101, and the like.
[0018] The operation unit 105 is used to receive instructions from the user for the camera 100. The operation unit 105 includes operation members such as a power button for the user to instruct ON / OFF of the power of the camera 100, a release switch for instructing shooting, and a playback button for instructing playback of image data. Also, a touch panel formed on the display unit 106 is included in the operation unit 105. Note that the release switch has switches SW1 and SW2. When the release switch is in a so-called half-pressed state, switch SW1 turns ON. Thereby, instructions for performing shooting preparations such as AF (auto focus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing are received. Also, when the release switch is in a so-called fully pressed state, switch SW2 turns ON. Thereby, an instruction for performing shooting is received.
[0019] The display unit 106 displays a live view image (LV image), which is an imaging image representing the subject almost in real time, a captured (recorded) imaging image, characters for interactive operations, and the like. Note that 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 only needs to have at least a display control function for controlling the display of 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 it may be built into the camera 100. The camera 100 only needs to have the function to access 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 enables wireless communication with the external device by controlling the connection unit 111.
[0022] Furthermore, camera 100 can operate as a slave device in the infrastructure mode of wireless LAN communication. When operating as a slave device, it can connect to nearby access points (hereinafter referred to as APs) and participate in the network formed by the APs. In addition, although camera 100 is a type of AP, it can also operate as a simpler AP with more limited functionality (hereinafter referred to as a simple AP). Note that an AP is an example of a relay device. When camera 100 operates as a simple AP, camera 100 forms its own network. Devices around camera 100 recognize camera 100 as an AP and can participate in the network formed by camera 100. The program for operating camera 100 in this way is stored in non-volatile memory 103. Note that although camera 100 is a type of AP, it is a simple AP that does not have a gateway function to transfer data received from slave devices to an internet provider or the like. Therefore, even if it receives data from other devices participating in the network it has formed, it cannot transfer it to the internet or other networks. Alternatively, connection part 1 11 may be a wired communication interface instead of wireless communication.
[0023] Furthermore, as mentioned above, the method of communication with external devices is not particularly limited. The connection section 111 may be an interface for wired communication using methods such as RS-232C, RS-422A, USB, or Ethernet®.
[0024] (Smartphone configuration) Figure 2(B) is a block diagram showing an example 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 a 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 various parts of the smartphone 200 according to the input signals and the program described later. Alternatively, instead of the control unit 201 controlling the entire smartphone 200, multiple hardware components may share the processing to control the entire smartphone 200.
[0026] The imaging unit 202 converts the subject light, which is imaged by the lens included in the imaging unit 202, into an electrical signal, performs noise reduction processing, and outputs the digital data as image data. The captured image data is stored in a buffer memory, then processed by the control unit 201, and recorded on the recording medium 210.
[0027] The non-volatile memory 203 is an electrically erasable and recordable non-volatile memory that stores the operating system (OS), which is the basic software executed by the control unit 201, and various programs. The program for communicating with the camera 100 is also held in the non-volatile memory 203 and installed as a camera control application. The processing of the smartphone 200 is realized by loading the camera control application program. The camera control application has functions for utilizing the basic functions of the OS installed on the smartphone 200 (for example, wireless LAN function, Bluetooth function, function to call other applications, etc.). The camera control application also has a remote shooting function that allows the user to remotely control the camera 100 from the smartphone 200 and take pictures while viewing the LV image obtained from the camera 100 on the smartphone 200. Furthermore, the camera control application has a remote viewing function that allows the user to remotely view image data stored on the recording medium attached to the camera 100 and to receive such image data. The OS of the smartphone 200 may have the functions of this embodiment (for example, the functions of the camera control application).
[0028] The working memory 204 is used as a buffer memory for temporarily storing image data captured by the imaging unit 202, as well as as an image display memory for the display unit 206 and a working area for the control unit 201.
[0029] The control unit 205 is used to receive instructions from the user for the smartphone 200. The control unit 205 includes, for example, a power button for the user to instruct the smartphone 200 to turn on or off, and an operating component such as a touch panel formed on the display unit 206.
[0030] The display unit 206 displays images, text for interactive operation, etc. Note that the smartphone 200 does not necessarily need to have a built-in display unit 206. The smartphone 200 can connect to an internal or external display unit 206 and only needs to have at least a display control function to control 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, and the like. The recording medium 210 may be detachable from the smartphone 200, or it may be built into the smartphone 200. The smartphone 200 only needs to have the ability 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 Wi-Fi. The control unit 201 enables wireless communication with the external device by controlling the connection unit 211.
[0033] Furthermore, the smartphone 200 can operate as a slave device in the infrastructure mode of wireless LAN communication and can participate in the network formed by surrounding access points (APs). Alternatively, 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 those other devices and voice calls with the users of those other devices. During a call, the control unit 201 acquires voice signals via the microphone 213 and outputs voice signals via the speaker 214. The public network connection unit 212 may include an interface for communication using, for example, 3G, 4G, or 5G. The communication method is not particularly limited and may include, for example, LTE, WiMAX, ADSL, or FTTH. The connection unit 211 and the public network connection unit 212 do not necessarily need to be composed of independent hardware; for example, one antenna may serve as both the connection unit 211 and the public network connection unit 212.
[0035] In the following description, it may be stated that the smartphone 200 is the main processing unit, but in reality, the control unit 201 reads and executes programs stored in the non-volatile memory 203 to perform various processes. Similarly, it may be stated that the camera 100 is the main processing unit, but in reality, the control unit 101 reads and executes programs stored in the non-volatile memory 103 to perform various processes.
[0036] (Example of a smartphone screen) Figures 3-6 are schematic diagrams showing examples of screens for a camera control application displayed on the display unit 206 by a smartphone 200. The camera control application connects to multiple cameras simultaneously and enables operation of each camera. The camera control application also receives LV images and various data from the cameras through communication and displays them on the display unit 206. The display unit 206 is assumed to be a display unit that can accept touch operations, such as a display unit with a touch panel.
[0037] Figure 3 is a schematic diagram showing an example of the main screen and multi-screen of a camera control application. Figure 3(A) shows an example of the main screen. In Figure 3(A), the control unit 201 is connected to the camera by the camera control application and receives the 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 at the top of the main screen 301 for changing various settings. For example, the control unit 201 displays a camera connection setting button 311, a multi-view switching switch 312, a view switching 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 other setting buttons 317 on the header unit 310.
[0039] The camera connection setting button 311 is a setting button for connecting and disconnecting the camera. The view switching button 313 is a setting button for selecting display modes (views) such as normal display mode, multi-screen display mode, and full-screen display mode for the LV image (each display mode will be explained later). The assist setting button 315 is a setting button for selecting assist functions such as magnified display, marker display, and phosphor color display (each assist function will be explained later). The other setting button 317 is a setting button for other settings. When the user touches one of these setting buttons, the control unit 201 transitions the display screen (the screen that is displayed) to the setting screen corresponding to the touched setting button.
[0040] The multi-view toggle switch 312 is a toggle switch for enabling / disabling the multi-view function. The LV display switch 314 is a toggle switch for enabling / disabling the LV display function. The screen lock switch 316 is a toggle switch for enabling / disabling the screen lock function. Details of these functions will be described later. When a user touches one of these toggle switches, the control unit 201 toggles the function corresponding to the touched toggle switch between enabled and disabled. In Figure 3(A), the multi-view toggle switch 312 is disabled, the LV display switch 314 is enabled, and the screen lock switch 316 is disabled. 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.
[0041] The control unit 201 also displays the LV area 320 and sub-LV area 330 on the main screen 301. The control unit 201 displays the 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 Figure 3(A), four cameras (Camera1 to 4) are connected, and four LV images 331 to 334 acquired from each of the four cameras 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 target of operation. In Figure 3(A), LV image 331 (Camera1) is selected. The control unit 201 displays a cursor surrounding LV image 331 to indicate that LV image 331 is selected. The control unit 201 then displays the same LV image as LV image 331 in 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 being operated, and a recording start / stop button 341 for instructing the start or stop of 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 being operated to start or stop recording images. The control unit 201 displays a group of operation buttons in the operation area 350. The current setting value that can be changed by pressing the operation button is displayed on the operation button. When the user touches an operation button, the control unit 201 instructs the camera being 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 a 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 did not fit within the operation area 350.
[0043] Figure 3(B) shows an example of a multi-screen setup. For example, the display of the main screen 301 in Figure 3(A) When the user touches the multi-view switching switch 312, the control unit 201 transitions the display screen from the main screen 301 in Figure 3(A) to the multi-screen 302 in Figure 3(B). The multi-screen 302 is a screen for checking the recording status of connected cameras all at once, and the LV area 320 and the operation area 350 are not displayed on the multi-screen 302.
[0044] The control unit 201 displays the header section 310 at the top of the multi-screen 302. In Figure 3(B), unlike Figure 3(A), the multi-view switching switch 312 is enabled, indicating that the current display screen is the multi-screen. The control unit 201 displays all LV images and all recording statuses acquired from the connected cameras on the multi-screen 302. In Figure 3(B), four cameras (Camera1~4) are connected, and four LV images 361~364 acquired from each of the four cameras are displayed side by side. The arrangement of LV images 361~364 differs from the arrangement of LV images 331~334 in Figure 3(A), with LV images 361~364 being displayed at a larger size than LV images 331~334. The recording statuses 371~374 of the four cameras (Camera1~4) are displayed below LV images 361~364. 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 simultaneously instructs all cameras to start or stop recording images. Note that while the multi-screen 302 is displayed, it is not possible to select only one camera as the target of operation.
[0045] Figure 3(C) shows an example of the main screen when the LV display is disabled. For example, if the user touches the LV display switch 314 while the main screen 301 in Figure 3(A) is displayed, the control unit 201 transitions the display screen from the main screen 301 in Figure 3(A) to the main screen 303 in Figure 3(C). The main screen 303 is a screen in which the LV area 320 is hidden. The header section 310 is displayed at the top of the main screen 303. In Figure 3(C), unlike Figure 3(A), the LV display switch 314 on the header section 310 is disabled, indicating that the LV area 320 is hidden. The sub-LV area 330, the recording information area 340, and the operation area 350 are also displayed on the main screen 303. As the LV area 320 is hidden, the sub-LV area 330, the recording information area 340, and the operation area 350 move upwards. Furthermore, with the LV area 320 hidden, the operation area 350 has become larger, and the number of operation buttons displayed in the operation area 350 has increased. In Figure 3(C), all operation buttons are displayed in the operation area 350, so the control unit 201 does not accept slide operations on the operation area 350.
[0046] Figure 4 is a schematic diagram showing an example of a camera control application screen, illustrating an example of switching LV display modes.
[0047] Figure 4(A) shows an example of a screen in normal display mode. The screen 401 in Figure 4(A) is the same as the main screen 301 in Figure 3(A), but the display state (display content) of the header section 310 is different between Figure 4(A) and Figure 3(A). For example, when the user touches the view switching button 313 while the main screen 301 in Figure 3(A) is displayed, the control unit 201 switches the display state of the header section 310 from the state in Figure 3(A) to the state in Figure 4(A). In Figure 4(A), the header section 310 displays the normal display button 411, the 2x2 display button 412, the full-screen display button 413, and the back button 414. When the user touches the normal display button 411, the 2x2 display button 412, or the full-screen display button 413, the control unit 201 switches the display mode to the mode corresponding to the touched button. In Figure 4(A), a cursor is displayed surrounding the normal display button 411, indicating that the display mode is the normal display mode. When the user touches the back button 414, the control unit 201 returns the display state of the header section 310 from the state in Figure 4(A) to the state in Figure 3(A).
[0048] Figure 4(B) shows an example of a screen in 2x2 display mode. For example, when the user touches the 2x2 display button 412 while screen 401 in Figure 4(A) is displayed, the control unit 201 transitions the display screen from screen 401 in Figure 4(A) to screen 402 in Figure 4(B). The 2x2 display mode is a multi-screen display mode that displays the sub-LV area 330 without displaying the LV area 320, and displays four LV images in a 2x2 arrangement. In 2x2 display mode, the target camera is selected in response to a touch on the LV image in the sub-LV area 330, similar to the normal display mode (when screens 301 and 401 in Figures 3(A) and 4(A) are displayed). In Figure 4(B), a cursor is displayed surrounding the LV image (main image) of the target camera among the four LV images in a 2x2 arrangement. In Figure 4(B), screen 402 displays the recording information area 340 and the operation area 350, similar to screens 301 and 401 in Figures 3(A) and 4(A).
[0049] Figure 4(C) shows an example of the screen in full-screen display mode. For example, when the user touches the full-screen button 413 while screen 401 in Figure 4(A) is displayed, the control unit 201 transitions the display screen from screen 401 in Figure 4(A) to screen 403 in Figure 4(C). Full-screen display mode is a display mode in which the LV area 320 (main image) is displayed across the entire screen without displaying the sub-LV area 330, the recording information area 340, and the operation area 350. In the normal display mode (Figure 4(A)), screen 401 has the header section 310 (an operation area where multiple items for user operation are displayed), the LV area 320, and the sub-LV area 330 arranged vertically. In contrast, in full-screen display mode (Figure 4(C)), the full-screen header section 420 is superimposed on a part of the LV area 320. The full-screen header section 420 is an operation area where some of the multiple items for user operation are displayed. For example, in full-screen mode, the control unit 201 displays a reduced display toggle button 421 and an assist setting button 422 on the header section 420, overlaid on the main image displayed in the LV area 320. When the user touches the reduced display toggle button 421, the control unit 201 returns the display screen to the screen immediately preceding the full-screen display screen 403 (for example, screen 401 in Figure 4(A) or screen 402 in Figure 4(B)). The assist setting button 422, like the assist setting button 315, is a setting button for selecting assist functions such as magnified display, marker display, and phosphor color display. In addition, as a display mode similar to the full-screen display mode, a display mode may be set in which the LV area 320 is displayed larger than the LV area 320 in Figure 4(A), although not the entire screen.
[0050] Figure 5 is a schematic diagram showing an example screen of a camera control application, illustrating an example when magnification is enabled. The camera control application has a magnification function that crops and enlarges a portion of the LV image (main image) of the camera being controlled. In the magnification function, the control unit 201 loads the main image into the working memory 204, sets a portion of the main image as the magnification area, crops the image of the magnification area from the main image, resizes the cropped image, and displays it. By using the magnification function, the user can check the image quality, such as focus, in detail.
[0051] Figure 5(A) shows an example of the screen when magnified in normal display mode. The screen 501 in Figure 5(A) is the same as the main screen 301 in Figure 3(A), but the display state (display content) of the header section 310 is different between Figure 5(A) and Figure 3(A). For example, when the user touches the assist setting button 315 while the main screen 301 in Figure 3(A) is displayed, the control unit 201 switches the display state of the header section 310 from the state in Figure 3(A) to the state in Figure 5(A). In Figure 5(A), the header section 310 displays the WFM switch 511, the marker switch 512, the MAGN switch 513, the FalseColor switch 514, and the back button 515.
[0052] When the user touches the WFM switch 511, the control unit 201 switches the display of the waveform monitor image, which represents the brightness distribution of the LV image (main image) acquired from the camera being operated, on or off. When the user touches the marker switch 512, the control unit 201 switches the display of markers on or off. Markers are guide lines for composition confirmation, such as a center marker indicating the center of the image, a horizontal marker indicating the horizontal direction of the image, and grid markers that divide the image into multiple regions arranged horizontally and vertically. When the user touches the MAGN switch 513, the control unit 201 switches the magnified display of the LV image on or off. When the user touches the FalseColor switch 514, the control unit 201 switches the display of false color, which applies color to the LV image (converts each pixel value of the LV image to a pixel value corresponding to the brightness), on or off. When the user touches the back button 515, the control unit 201 returns the display state of the header unit 310 from the state in Figure 5(A) to the state in Figure 3(A).
[0053] Magnification is performed only in LV area 320. Waveform monitor images may not be displayed in multi-screen mode, or they may be displayed in 2x2 display mode when LV area 320 is not displayed. Markers are displayed only in LV area 320 when LV area 320 is displayed, and may be displayed on each LV image in 2x2 display mode when LV area 320 is not displayed or in multi-screen mode. False color display is performed in LV area 320, and may also be performed on the main image displayed in sub-LV area 330. False color display does not have to be performed on other LV images displayed in sub-LV area 330 or in multi-screen mode. By limiting the image on which false color display is performed to the main image, the main image stands out, and the user can easily grasp the main image.
[0054] In Figure 5(A), the WFM switch 511, marker switch 512, and FalseColor 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. When checking the magnified view, markers based on the entire LV image are not very useful as a reference, so when the MAGN switch 513 is enabled, the control unit 201 forcibly disables the marker switch 512. Similarly, when the MAGN switch 513 is enabled, the control unit 201 may forcibly disable the display of the AF frame that indicates the area to focus on. When displaying a multi-screen, the control unit 201 may forcibly disable the WFM switch 511, MAGN switch 513, and FalseColor switch 514. In 2x2 display mode, the control unit 201 may forcibly disable the MAGN switch 513. When the control unit 201 forcibly disables a switch, it may make it possible to identify that the switch has been forcibly disabled by displaying the switch in a grayed-out state or the like.
[0055] In Figure 5(A), the control unit 201 displays an enlarged version of the main image in the LV area 320, and overlays a MAGN icon 520 on the image to indicate that the enlargement display is enabled. 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 identifying the enlarged area is not particularly limited, but in Figure 5(A), a frame 521 (guide) surrounding the enlarged area and a mask 522 (for example, a black and semi-transparent mask) covering the area outside the enlarged area are overlaid on the main image displayed in the sub-LV area 330. This allows the user to easily grasp the enlarged area. Furthermore, by not displaying an item indicating the enlarged area in the LV area 320, the deterioration of the visibility of the main image displayed in the LV area 320 can be suppressed. Note that only one of the frame 521 or the mask 522 may be used.
[0056] In Figure 5(A), the control unit 201 controls other LV images displayed in the sub-LV area 330. However, the magnified area remains identifiable. When the main image (the camera being operated on) is switched, the control unit 201 displays the magnified area of the main image after the switch in the LV area 320 and continues the magnified display. This suppresses the frequent switching of the magnified display on and off, thereby reducing the complexity of user operation.
[0057] The control unit 201 records information about the magnified area of each LV image (each camera) in the non-volatile memory 203 and uses it for magnified display, display of the frame 521 and mask 522, etc. The default magnified area is not particularly limited, but for example, the control unit 201 sets the 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 size is 1 / 2 of the entire LV image) as the magnified area. In Figure 5(A), a default magnified area is set for all of Cameras 1 to 4. If magnified display is disabled, the control unit 201 does not need to make the magnified area identifiable in the sub-LV area 330.
[0058] Figure 5(B) shows an example of the screen when the magnification area is changed from the state in Figure 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 magnification area of the main image. A pinch operation is a touch operation in which two touch points are touched and brought closer or further apart. The position of the magnification area is changed in accordance with the slide operation, the magnification area is reduced in accordance with the pinch operation (pinch-in operation) which brings the two touch points closer together, and the magnification area is enlarged in accordance with the pinch operation (pinch-out operation) which moves the two touch points further apart. The position of the magnification area can also be changed by the pinch operation. In screen 502 of Figure 5(B), the magnification area of the main image has changed from Figure 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 Figure 5(A). For example, in Figure 5(A), the dog's body is displayed in LV region 320, but in Figure 5(B), the dog's head is displayed in LV region 320. Also, in Figure 5(A), frame 521 is displayed in the center of the main image in sub-LV region 330, but in Figure 5(B), frame 521 is displayed in the upper left of the main image in sub-LV region 330.
[0059] Figure 5(C) shows an example of the screen when enlarged in full-screen mode. Screen 503 in Figure 5(C) is the same as screen 403 in Figure 4(C), but in screen 503 of Figure 5(C), the WFM switch 511, marker switch 512, MAGN switch 513, and FalseColor are displayed. For example, when the user touches the assist setting button 422 while screen 403 of Figure 4(C) is displayed, the control unit 201 displays the WFM switch 511, marker switch 512, MAGN switch 513, and FalseColor. Then, when the user touches the assist setting button 422 again, the control unit 201 hides the WFM switch 511, marker switch 512, MAGN switch 513, and FalseColor.
[0060] In Figure 5(C), as in Figure 5(A), the WFM switch 511, marker switch 512, and FalseColor switch 514 are disabled, and the MAGN switch 513 is enabled. Also in Figure 5(C), as in Figure 5(A), the control unit 201 is performing an enlarged display of the main image in the LV area 320, and is displaying a MAGN icon 520 superimposed on the image to indicate that the enlarged display is enabled. In Figure 5(A), the control unit 201 made the enlarged area identifiable in the sub-LV area 330, but in Figure 5(C), the control unit 201 displays an item indicating the enlarged area in the LV area 320. In Figure 5(C), a reduced image 530 of the main image, with the enlarged area identifiable by a frame 521 and a mask 522, is displayed as the item indicating the enlarged area. Note that the item indicating the enlarged area is not limited to this; for example, a combination of a frame showing the entire main image and a frame showing the enlarged area may also be used. By displaying an item indicating the enlarged area, the user can easily grasp the enlarged area. Note that in full-screen mode, L Because the V area 320 is large (it covers the entire screen), displaying an item indicating the enlarged area does not significantly worsen the visibility of the main image displayed in the LV area 320.
[0061] Figure 6 is a schematic diagram showing an example of the camera control application screen, illustrating an example of when marker display is enabled. The camera control application has a marker function that overlays markers onto the LV image. The marker function is an assist function for confirming composition. The marker function allows for the display of various markers, such as a center marker indicating the center of the image, a horizontal marker indicating the horizontal direction of the image, and grid markers that divide the image into multiple regions arranged horizontally and vertically.
[0062] Figure 6(A) shows an example of the screen when marker display is enabled in normal display mode. Screen 601 in Figure 6(A) is the same as the main screen 301 in Figure 3(A), but the display state (display content) of the header section 310 is different between Figure 6(A) and Figure 3(A). In Figure 6(A), the header section 310 displays the WFM switch 511, marker switch 512, MAGN switch 513, FalseColor switch 514, and back button 515. In Figure 6(A), the WFM switch 511, MAGN switch 513, and FalseColor switch 514 are disabled, and the marker switch 512 is enabled.
[0063] In Figure 6(A), the control unit 201 overlays the marker 610 onto the main image displayed in the LV area 320. Since each LV image displayed in the sub-LV area 330 is small and the marker is not very useful as a reference, the control unit 201 does not display the marker in the sub-LV area 330. As mentioned above, in 2x2 display mode or multi-screen mode where the LV area 320 is not displayed, each LV image is relatively large, so the marker may be displayed on each LV image.
[0064] Figure 6(B) shows an example of the marker setting screen. For example, if, while screen 501 in Figure 6(A) is displayed, the user touches the back button 515 and then the other settings button 317 to instruct the start of marker setting, the control unit 201 transitions the display screen from screen 601 in Figure 6(A) to screen 602 in Figure 6(B). In screen 602 in Figure 6(B), the marker setting menu 620 is overlaid on screen 601 in Figure 6(A). The user can display their preferred markers by operating the marker setting menu 620. In Figure 6(B), the center marker and grid marker are enabled, and in Figures 6(A) to 6(C), the center marker and grid marker are displayed in the LV area 320.
[0065] In addition, the control unit 201 may prepare multiple setting values corresponding to multiple LV images (multiple cameras) as marker setting values. However, in this embodiment, a common marker setting value for all LV images (all cameras) is recorded in the non-volatile memory 203. Therefore, even if the main image (the camera being operated on) is switched, the same marker will continue to be displayed.
[0066] Figure 6(C) shows an example of the screen when markers are displayed in full-screen mode. Screen 603 in Figure 6(C) is the same as screen 403 in Figure 4(C), but screen 503 in Figure 6(C) displays the WFM switch 511, marker switch 512, MAGN switch 513, and FalseColor. In Figure 6(C), the WFM switch 511, MAGN switch 513, and FalseColor switch 514 are disabled, and the marker switch 512 is enabled. Also in Figure 6(C), as in Figure 6(A), the control unit 201 overlays the marker 610 onto the main image displayed in the LV area 320.
[0067] (Overall operation of the smartphone) Figure 7 is a flowchart showing the overall operation of the smartphone 200. The overall operation shown in Figure 7 is achieved when the control unit 201 loads a program (for example, a camera control application program) stored in the non-volatile memory 203 into the working memory 204 and executes it. For example, when the camera control application is instructed to start, the overall operation shown in Figure 7 begins.
[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, setting values, LV image, etc.
[0070] In S703, the control unit 201 obtains screen information from the working memory 204 that indicates the type of screen to be displayed on the display unit 206. When the smartphone 200 (camera control application) is started, screen information indicating the main screen with LV display (display of LV area 320) (screen in normal display mode) is stored. When the control unit 201 changes the screen in response to user operation, it updates the screen information recorded in the working 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 full-screen mode (whether the screen information acquired in S703 indicates a screen in full-screen mode). If it is full-screen mode, proceed to S705; otherwise, proceed to S714.
[0072] In S705, the control unit 201 displays the header section 420 when the screen is full screen.
[0073] In S706, the control unit 201 reads information from the working memory 204 indicating whether the magnification function (magnified display) is enabled or disabled, and determines whether the magnification function is enabled or disabled. If the magnification function is enabled, the process proceeds to S707; otherwise, it proceeds to S711.
[0074] At the start of the overall operation shown in Figure 7, the control unit 201 loads the information of the enlarged area stored in the non-volatile memory 203 into the working memory 204. In S707, the control unit 201 reads the information of the enlarged area of the main image (LV image of the camera being operated) from the working memory 204, extracts the image of the enlarged area from the main image, and displays it on the entire screen (LV area 320 in Figure 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 overlays the reduced image 530 of Figure 5(C) (a reduced image of the main image 530) onto the main image displayed in S707.
[0076] In S709, the control unit 201 overlays the frame 521 and mask 522 shown in Figure 5(C) onto 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 shown in Figure 5(C) overlaid on the main image displayed in S707.
[0078] Figure 5(C) shows the result when the display is enlarged in full-screen mode using S705~S710. Screen 503 is displayed.
[0079] In S711, the control unit 201 displays the main image across the entire screen (LV area 320 in Figures 4(C) and 6(C)).
[0080] In S712, the control unit 201 reads information from the working memory 204 indicating whether the marker function (marker display) is enabled or disabled, and determines whether the marker function is enabled or disabled. If the marker function is enabled, the process proceeds to S713; otherwise, it proceeds to S730.
[0081] At the start of the overall operation shown in Figure 7, the control unit 201 loads the marker setting values stored in the non-volatile 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 overlaid on the main image displayed in S711.
[0082] S705, S706, S711, and S712 display screen 403 in Figure 4(C) when neither zoom nor marker display is performed in full-screen mode. Performing S713 further displays screen 603 in Figure 6(C) when marker display is performed in full-screen mode.
[0083] In S714, the control unit 201 displays the header section 310.
[0084] In S715, the control unit 201 determines whether the screen information acquired in S703 indicates a multi-screen display. If it indicates a multi-screen display, the process proceeds to S716; otherwise, it proceeds to S718.
[0085] In S716, the control unit 201 displays all LV images (LV images 361-364 in Figure 3(B)) acquired from the connected camera.
[0086] In S717, the control unit 201 displays all recording statuses acquired from the connected camera (recording statuses 371-374 in Figure 3(B)) and the recording start / stop button 341 in Figure 3(B).
[0087] The multi-screen 302 shown in Figure 3(B) is displayed by steps S714 to S717. When displaying the multi-screen 302, the zoom 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 the screen information acquired in S703 indicates the main screen with LV display (display of LV area 320). If it indicates the main screen with LV display, proceed to S719; otherwise, proceed to S728.
[0089] In S719, the control unit 201 displays the sub-LV area 330 shown in Figures 3(A), 5(A), and 6(A).
[0090] In S720, the control unit 201 displays the recording information area 340 and the operation area 350 as shown in Figures 3(A), 5(A), and 6(A).
[0091] In S721, the control unit 201 reads information from the working memory 204 indicating whether the magnification function (magnified display) is enabled or disabled, and determines whether the magnification function is enabled or disabled. If the magnification function is enabled, the process proceeds to S722; otherwise, it proceeds to S725.
[0092] In S722, the control unit 201 reads information about the enlarged area of the main image from the working memory 204, extracts the image of the enlarged area from the main image, and displays it in the LV area 320 in Figure 5(A).
[0093] In S723, the control unit 201 overlays the frame 521 and mask 522 shown in Figure 5(A) onto each LV image of the sub-LV region 330 displayed in S719.
[0094] In S724, the control unit 201 displays the MAGN icon 520 shown in Figure 5(A) overlaid on the main image displayed in S722.
[0095] S714, S715, and S718-S724 display the screen 501 shown in Figure 5(A) when the display is magnified in the normal display mode with LV display.
[0096] In S725, the control unit 201 displays the main image in the LV area 320 shown in Figures 4(A) and 6(A).
[0097] In S726, the control unit 201 reads information from the working memory 204 indicating whether the marker function (marker display) is enabled or disabled, and determines whether the marker function is enabled or disabled. If the marker function is enabled, the process proceeds to S727; otherwise, it proceeds to S730.
[0098] In S727, the control unit 201 reads the marker setting value from the working memory 204 and displays the marker overlaid on the main image displayed in S725.
[0099] S714, S715, S718-S721, S725, and S726 display screen 401 in Figure 4(A), which is the normal display mode with LV display enabled and neither magnification nor marker display is performed. Performing S727 further displays screen 601 in Figure 6(A), which is the normal display mode with LV display enabled and marker display is performed.
[0100] In S728, the control unit 201 displays the sub-LV area 330 in Figure 3(C).
[0101] In S729, the control unit 201 displays the recording information area 340 and the operation area 350 shown in Figure 3(C).
[0102] S714, S715, S718, S728, and S729 display screen 403 in Figure 4(C) in normal display mode without LV display. When displaying screen 403, the zoom function and marker function are ignored, and screen 403 does not change regardless of whether they are enabled or disabled.
[0103] In S730, the control unit 201 determines whether it has received a user operation. If it has received a user operation, it proceeds to S731; otherwise, it proceeds to S702. A user operation is, for example, a touch operation on the 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 application termination operation. If it is an application termination operation, the entire operation shown in Figure 7 is terminated; otherwise, the process proceeds to S732.
[0105] In S732, the control unit 201 performs processing in response to user operations received in S730. For example, it may change the display mode or modify camera setting parameters.
[0106] According to the overall operation described above, on the main screen, the item indicating the enlarged area is LV area 32 By not displaying 0, the deterioration of visibility of the main image displayed in the LV area 320 can be suppressed. Furthermore, by displaying an item indicating the enlarged area in the sub-LV area 330, the user can easily grasp the enlarged area. Even in full-screen mode, by displaying an item indicating the enlarged area in the LV area 320, the user can easily grasp the enlarged area. In full-screen mode, the LV area 320 is large (the entire screen), so even if an item indicating the enlarged area is displayed, the visibility of the main image displayed in the LV area 320 is hardly deteriorated. Markers can be suitably used for confirming the composition of LV images displayed at a relatively large size, so they are displayed in the LV area 320 but not in the sub-LV area 330.
[0107] Note that the overall operation in Figure 7 omits the case of 2x2 display mode, but for example, in the case of 2x2 display mode, it may be the same as when displaying the main screen without LV display.
[0108] Although embodiments of the present invention have been described in detail above, the present invention is not limited to these specific embodiments, and various forms that do not depart from the spirit of the invention are also included in the present invention. Some of the above embodiments may be combined as appropriate.
[0109] For example, in the above embodiment, when magnification is performed in the LV area 320, the sub-LV area 330 is made able to identify the magnified area of all LV images, but it is not limited to this. When magnification is performed in the LV area 320, it may be possible to set whether or not to make the sub-LV area 330 able to identify the magnified area of LV images that are not the main image.
[0110] Furthermore, while the above-described embodiment assumes that the magnification area of each LV image (each camera) is set individually, this is not the only option. The magnification areas of other LV images may be changed in conjunction with changes to the magnification area of the main image. For example, the magnification areas of each LV image may be set so that the position (relative position) and size (relative size) of the magnification 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 magnification area of non-main LV images to the main image.
[0111] For example, a settings menu 801, as shown in Figure 8(A), may be displayed, allowing the user to specify (select) whether or not to make the enlarged area of a non-main LV image identifiable, or whether or not to link the enlarged area of a non-main LV image to the main image.
[0112] The enlarged area of the main image and the enlarged area set for non-main LV images may be distinguished in different ways. For example, frames of different colors, brightness levels, and line types may be used, or masks of different colors, brightness levels, and transparency levels may be used.
[0113] As shown in Figure 8(B), due to the difference in aspect ratio between the LV area 320 and the main image's enlarged area, a margin may appear in the LV area 320 that includes a predetermined size area (an area where an item indicating the enlarged area can be displayed). In such cases, the item indicating the enlarged area may be displayed in the margin. In Figure 8(B), a reduced image 802, with the enlarged area identifiable by a frame, is displayed in the margin. However, if the main image is a specific image, an item indicating the enlarged area may also be displayed in the LV area 320. A specific image is one in which a deterioration in visibility due to the item indicating the enlarged area is acceptable. For example, a specific image may be one with low resolution, making it difficult to see details even when enlarged. A specific image may be one with few subjects, such as a blue sky, which is not frequently enlarged. If the enlarged area has a background that includes a predetermined size area, the item indicating the enlarged area may be displayed on that background.
[0114] Furthermore, while we have described an example of applying the present invention when checking LV images from multiple cameras, other examples exist. The present invention is applicable to a variety of cases. For example, the present invention is applicable when multiple videos shot with multiple video cameras are stored on a storage medium, and the multiple videos are read from the storage medium and edited.
[0115] The various controls described above may or may not be performed by a single piece of hardware (e.g., a processor or circuit). Multiple pieces of hardware (e.g., multiple processors, multiple circuits, or a combination of one or more processors and one or more circuits) may share the processing to control the entire device.
[0116] Furthermore, the above-mentioned processors are processors in a broad sense, including general-purpose processors and specialized processors. General-purpose processors include, for example, CPUs (Central Processing Units), MPUs (Micro Processing Units), and DSPs (Digital Signal Processors). Specialized 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] Furthermore, although embodiments of the present invention have been described in detail, the present invention is not limited to these specific embodiments, and various forms that do not depart from the spirit of the invention are also included in the present invention. Moreover, each of the embodiments described above is merely one embodiment of the present invention, and it is possible to combine each embodiment as appropriate.
[0118] <Other Embodiments> The present invention can also be realized by supplying a program that implements one or more of the functions of the above-described embodiments to a system or device via a network or storage medium, and by having one or more processors in the computer of that system or device read and execute the program. It can also be realized by a circuit that implements one or more functions.
