Description

Technical Field

[0001] The present invention relates to an electronic device and a method for controlling an electronic device.

Background Art

[0002] There is a known technique for displaying a stereoscopic VR (Virtual Reality) image by acquiring images with a wide viewing angle having parallax using two optical systems and mapping and displaying them on a virtual sphere. A binocular VR camera for capturing images with parallax has two optical systems facing the same direction, and two image regions with parallax can be acquired by one shooting. There are binocular VR cameras that can shoot a wide range of 180 degrees or more (hemisphere, 90 degrees in all directions from the image center) in the vertical and horizontal directions in each optical system. As methods for displaying VR images, there are known "monocular VR display" in which a VR image is mapped onto a virtual sphere and transformed to display one image, and "binocular VR display" in which VR image regions for the left eye and the right eye are arranged side by side and displayed.

[0003] A camera that can be used by swapping a monocular lens and a binocular lens makes it easy to understand that shooting is being performed with the binocular lens by arranging the image regions captured by the left-eye optical system and the right-eye optical system side by side for binocular display during shooting with the binocular lens.

[0004] Patent Document 1 discloses an electronic device that displays two fisheye image regions of a cutout range and an exclusion range, and when a pinch operation-based enlargement instruction is received for any of the image regions, the image region with the enlargement instruction is enlarged and displayed.

[Figure 7] This is a flowchart illustrating the camera magnification process according to Embodiment 2. [Modes for carrying out the invention]

[0011] [Embodiment 1] Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, the case in which the electronic device is a digital camera (imaging device) will be described as an example. The digital camera according to this embodiment can acquire a single image (two-lens image) including a left image area and a right image area having a predetermined parallax in the left-right direction, and display it on a display unit.

[0012] <Hardware Configuration> Figures 1(A) and 1(B) are external views showing an example of the external appearance of the digital camera (camera) 100 according to this embodiment. Figure 1(A) is a perspective view of the camera 100 as seen from the front, and Figure 1(B) is a perspective view of the camera 100 as seen from the rear.

[0013] Camera 100 has a shutter button 101, a power switch 102, a mode selector switch 103, a main electronic dial 104, a sub electronic dial 105, a video button 106, and an external viewfinder display 107 on its top surface.

The power switch 102 is an operating element for switching the power of camera 100 on and off. The mode selector switch 103 is an operating element for switching between various modes. The main electronic dial 104 is a rotary operating element for changing settings such as shutter speed and aperture. The sub electronic dial 105 is a rotary operating element for moving the selection frame (cursor) and advancing images. The video button 106 is an operating element for giving instructions to start and stop video recording. The external viewfinder display 107 displays various settings such as shutter speed and aperture.

[0014] The camera 100 has, on its back, a display unit 108, a touch panel 109, direction keys 110, a SET button 111, an AE lock button 112, a zoom button 113, a playback button 114, a menu button 115, an eyepiece 116, an eyepiece detection unit 118, and a touch bar 119. The display unit 108 displays images and various types of information. The touch panel 109 is an operation member that detects touch operations on the display surface (touch operation surface) of the display unit 108. The direction keys 110 are an operation member composed of keys that can be pressed respectively in the up, down, left, and right directions (4-direction keys). The user can perform an operation according to the position where the direction keys 110 are pressed. The SET button 111 is an operation member that is mainly pressed when determining a selected item. The AE lock button 112 is an operation member that is pressed when fixing the exposure state in the shooting standby state. The zoom button 113 is an operation member for switching between on and off of the zoom mode in the live view display (LV display) in the shooting mode. When the zoom mode is on, by operating the main electronic dial 104, the live view image (LV image) is enlarged or reduced. Also, the zoom button 113 is used when enlarging a playback image or increasing the magnification rate in the playback mode. The playback button 114 is an operation member for switching between the shooting mode and the playback mode. In the shooting mode, the user can shift to the playback mode by pressing the playback button 114, and display the latest image among the images recorded on the recording medium 227 in FIG. 2 on the display unit 108.

[0015] The menu button 115 is an operation member that is pressed to display a menu screen on which various settings can be made on the display unit 108. The user can intuitively perform various settings using the menu screen displayed on the display unit 108, the direction keys 110, and the SET button 111. The eyepiece part 116 is a part where the user looks into the eyepiece finder (peephole-type finder) 117. The user can view the video displayed on the EVF 217 (Electronic View Finder) in FIG. 2 inside the camera 100 through the eyepiece part 116. The eyepiece detection unit 118 is a sensor that detects whether or not the user is looking into the eyepiece part 116 (eyepiece finder 117).

[0016] The touch bar 119 is a linear touch operation member (line touch sensor) that can accept touch operations. The touch bar 119 is arranged at a position where it can be touched (touched) with the right thumb in a state where the grip part 120 is held with the right hand (a state where it is held with the little finger, ring finger, and middle finger of the right hand) so that the shutter button 101 can be pressed with the index finger of the right hand. That is, the touch bar 119 can be operated in a state (shooting posture) where the user looks into the eyepiece finder 117 and looks into the eyepiece part 116 and can press the shutter button 101 at any time. The touch bar 119 can accept a tap operation on the touch bar 119 (an operation of touching and releasing without moving the touch position within a predetermined period), a slide operation to the left and right (an operation of moving the touch position while keeping the touch after touching), and the like. The touch bar 119 is an operation member different from the touch panel 109 and does not have a display function. The touch bar 119 functions as, for example, a multi-function bar (M-Fn bar) to which various functions can be assigned.

[0017] The camera 100 also includes a grip section 120, a thumb rest section 121, a terminal cover 122, a lid 123, a communication terminal 124, etc. The grip section 120 is a holding section shaped to be easily gripped by the user with their right hand when holding the camera 100. With the camera 100 held by gripping the grip section 120 with the little finger, ring finger, and middle finger of the right hand, the shutter button 101 and the main electronic dial 104 are positioned to be operated by the index finger of the right hand. Similarly, in the same position, the sub electronic dial 105 and the touch bar 119 are positioned to be operated by the thumb of the right hand. The thumb rest section 121 (thumb standby position) is a grip section located on the back of the camera 100, in a place where it is easy to rest the thumb of the right hand holding the grip section 120 when no operating members are being operated. The thumb rest section 121 is made of a rubber material or the like to enhance the holding force (grip feel). The terminal cover 122 protects connectors such as connection cables that connect the camera 100 to external equipment (external devices). The cover 123 protects the recording medium 227 and the slot for storing the recording medium 227 by closing the slot. The communication terminal 124 is a terminal for communicating with the lens unit (lens unit 200 in Figure 2, lens unit 300 in Figure 3) which is detachable from the camera 100.

[0018] <Camera internal hardware configuration> Figure 2 is a block diagram showing the configuration of camera 100. Components identical to those in Figures 1(A) and 1(B) are denoted by the same reference numerals, and their descriptions are omitted as appropriate. In Figure 2, a lens unit 200 is attached to camera 100.

[0019] First, let's describe the lens unit 200. The lens unit 200 is a type of interchangeable lens unit that can be attached to and removed from the camera 100. The lens unit 200 is a single-lens unit (monocular lens unit) and is an example of a typical lens unit. The lens unit 200 includes an aperture 201, a lens 202, an aperture drive circuit 203, an AF (autofocus) drive circuit 204, a lens system control circuit 205, a communication terminal 206, etc.

[0020] The aperture 201 is configured to have an adjustable aperture diameter. The lens 202 is composed of multiple lenses. The aperture drive circuit 203 adjusts the amount of light by controlling the aperture diameter of the aperture 201. The AF drive circuit 204 drives the lens 202 to focus. The lens system control circuit 205 controls the aperture drive circuit 203, the AF drive circuit 204, etc., based on instructions from the system control unit 50, which will be described later. The lens system control circuit 205 controls the aperture 201 via the aperture drive circuit 203 and focuses by changing the position of the lens 202 via the AF drive circuit 204. The lens system control circuit 205 can communicate with the camera 100. Specifically, the lens system control circuit 205 communicates with the camera 100 via the communication terminal 206 of the lens unit 200 and the communication terminal 124 of the camera 100. The communication terminal 206 is a terminal for the lens unit 200 to communicate with the camera 100.

[0021] Next, the camera 100 will be described. The camera 100 includes a shutter 210, an imaging unit 211, an A / D converter 212, a memory control unit 213, an image processing unit 214, a memory 215, a D / A converter 216, an EVF 217, a display unit 108, and a system control unit 50.

[0022] The shutter 210 is a focal-plane shutter that can freely control the exposure time of the imaging unit 211 based on instructions from the system control unit 50. The imaging unit 211 is an image sensor composed of a CCD or CMOS element, etc., which converts an optical image into an electrical signal. The imaging unit 211 may have an image plane phase difference sensor that outputs defocus amount information to the system control unit 50. The A / D converter 212 converts the analog signal output from the imaging unit 211 into a digital signal. The image processing unit 214 performs predetermined processing (pixel interpolation, resizing such as reduction, color conversion, etc.) on the data from the A / D converter 212 or the data from the memory control unit 213. The image processing unit 214 also performs predetermined calculation processing using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation results. Through this processing, TTL (through-the-lens) AF processing, AE (automatic exposure) processing, EF (flash pre-flash) processing, etc. are performed. Furthermore, the image processing unit 214 performs predetermined calculations using the captured image data, and the system control unit 50 performs TTL-type AWB (auto white balance) processing based on the obtained calculation results.

[0023] Image data from the A / D converter 212 is written to the memory 215 via the image processing unit 214 and the memory control unit 213. Alternatively, image data from the A / D converter 212 is written to the memory 215 via the memory control unit 213 without going through the image processing unit 214. The memory 215 stores image data obtained by the imaging unit 211 and converted into digital data by the A / D converter 212, as well as image data for display on the display unit 108 and EVF 217. The memory 215 has sufficient storage capacity to store a predetermined number of still images, a predetermined amount of video footage, and audio. The memory 215 also serves as a memory for image display (video memory).

[0024] The D / A converter 216 converts the display image data stored in the memory 215 into an analog signal and supplies it to the display unit 108 and EVF 217. Therefore, the display image data written to the memory 215 is displayed on the display unit 108 and EVF 217 via the D / A converter 216. The display unit 108 and EVF 217 perform display according to the analog signal from the D / A converter 216. The display unit 108 and EVF 217 are displays such as LCDs and OLEDs. The digital signal converted by the A / D converter 212 and stored in the memory 215 is converted into an analog signal by the D / A converter 216 and sequentially transferred to the display unit 108 and EVF 217. The display unit 108 and EVF 217 perform live view display by displaying the sequentially transferred analog signal.

[0025] The system control unit 50 is a control unit consisting of at least one processor and / or at least one circuit. That is, the system control unit 50 may be a processor, a circuit, or a combination of a processor and a circuit. The system control unit 50 controls the entire camera 100. The system control unit 50 implements each process of the flowchart described later by executing a program recorded in the non-volatile memory 219. The system control unit 50 also performs display control by controlling the memory 215, D / A converter 216, display unit 108, EVF 217, etc.

[0026] The camera 100 also includes a system memory 218, a non-volatile memory 219, a system timer 220, a communication unit 221, a posture detection unit 222, and an eyepiece detection unit 118.

[0027] For example, RAM is used as the system memory 218. The system memory 218 stores constants and variables for the operation of the system control unit 50, programs read from the non-volatile memory 219, etc. The non-volatile memory 219 is an electrically erasable and recordable memory, and for example, EEPROM is used as the non-volatile memory 219. The non-volatile memory 219 stores constants and programs for the operation of the system control unit 50, etc. The program here refers to a program for executing the flowchart described later. The system timer 220 is a timing unit that measures the time used for various controls and the time of the built-in clock. The communication unit 221 transmits and receives video signals and audio signals to and from external devices connected by wireless or wired cables. The communication unit 221 can also connect to wireless LAN (Local Area Network) and the internet. In addition, the communication unit 221 can communicate with external devices using Bluetooth® and Bluetooth Low Energy. The communication unit 221 can transmit images (including live images) captured by the imaging unit 211 and images recorded on the recording medium 227, and can receive images and other various information from external devices. The attitude detection unit 222 detects the attitude (tilt) of the camera 100 with respect to the direction of gravity. Based on the attitude detected by the attitude detection unit 222, it can detect the tilt angle of the camera 100 in the horizontal (left-right) or vertical (up-down; front-back) direction. Also, based on the attitude detected by the attitude detection unit 222, it can determine whether the image taken by the imaging unit 211 was taken with the camera 100 held horizontally or vertically. The system control unit 50 can add orientation information corresponding to the attitude detected by the attitude detection unit 222 to the image file of the image taken by the imaging unit 211, or rotate the image according to the detected attitude. The attitude detection unit 222 can also detect the movement of the camera 100 (pan, tilt, lift, whether it is stationary or not, etc.). The attitude detection unit 222 can use, for example, an acceleration sensor or a gyroscope.

[0028] The eyepiece detection unit 118 can detect the approach of any object to the eyepiece unit 116 (eyepiece finder 117). For example, an infrared proximity sensor can be used for the eyepiece detection unit 118. When an object approaches, infrared light emitted from the light emitter of the eyepiece detection unit 118 is reflected by the object and received by the light receiver of the infrared proximity sensor. The eyepiece detection unit 118 can determine the distance from the eyepiece unit 116 to the object based on the amount of infrared light received. In this way, the eyepiece detection unit 118 performs eyepiece detection to detect the proximity distance of an object to the eyepiece unit 116. The eyepiece detection unit 118 is an eyepiece detection sensor that detects the approach (eye-catching) and departure (eye-moving) of an object (eye) to the eyepiece unit 116. The eyepiece detection unit 118 detects that an object has been caught in the eye when an object that approaches within a predetermined distance from the eyepiece unit 116 is detected from a non-eyepiece state (non-approach state). On the other hand, the eyepiece detection unit 118 detects that the eyepiece has been removed when the object that was detected as approaching moves beyond a predetermined distance from the eyepiece state (close state). The threshold for detecting eyepiece contact and the threshold for detecting eye separation may be different, for example, by providing hysteresis. Furthermore, the eyepiece state is assumed to be from the time eyepiece contact is detected until eye separation is detected. The non-eyepiece state is assumed to be from the time eye separation is detected until eyepiece contact is detected again. The system control unit 50 performs eyepiece detection Depending on the state detected by unit 118, the display unit 108 and EVF 217 are switched between display (display state) and hidden (hidden state). Specifically, when the system control unit 50 is at least in the shooting standby state and the display destination switching setting is set to automatic switching, the system control unit 50 sets the display destination to the display unit 108 and turns on the display, and hides the EVF 217 when the user is not using an eyepiece. Also, when the user is using an eyepiece, the system control unit 50 sets the display destination to the EVF 217 and turns on the display, and hides the display unit 108. Note that the eyepiece detection unit 118 is not limited to an infrared proximity sensor, but may be any other sensor that can detect a state that can be considered as an eyepiece.

[0029] The camera 100 also includes an external viewfinder display unit 107, an external viewfinder display drive circuit 223, a power control unit 224, a power supply unit 225, a recording medium interface 226, an operation unit 228, and the like.

[0030] The external viewfinder display unit 107 is driven by the external viewfinder display drive circuit 223 and displays various settings of the camera 100, such as shutter speed and aperture. The power control unit 224 consists of a battery detection circuit, a DC-DC converter, a switch circuit for switching which blocks are energized, and detects whether a battery is installed, the type of battery, and the remaining battery level. The power control unit 224 also controls the DC-DC converter based on the detection results and instructions from the system control unit 50, supplying the necessary voltage to each part, including the recording medium 227, for the required period. The power supply unit 225 includes primary batteries such as alkaline batteries and lithium batteries, secondary batteries such as NiCd batteries, NiMH batteries and Li batteries, and an AC adapter. The recording medium I / F 226 is an interface with the recording medium 227, such as a memory card or hard disk. The recording medium 227 is a memory card or the like for recording captured images and consists of semiconductor memory or a magnetic disk. The recording medium 227 may be detachable from the camera 100 or may be built into the camera 100.

[0031] The operation unit 228 is an input unit that receives user input (user operation) and is used to input various instructions to the system control unit 50. The operation unit 228 includes the shutter button 101, power switch 102, mode switch 103, touch panel 109, and other operation units 229. Other operation units 229 include the main electronic dial 104, sub electronic dial 105, video button 106, directional keys 110, SET button 111, AE lock button 112, zoom button 113, playback button 114, menu button 115, touch bar 119, and the like.

[0032] The shutter button 101 has a first shutter switch 230 and a second shutter switch 231. The first shutter switch 230 turns on during the operation of the shutter button 101, so-called half-press (shooting preparation instruction), and outputs a first shutter switch signal SW1. The system control unit 50 starts shooting preparation processing such as AF processing, AE processing, AWB processing, and EF processing in response to the first shutter switch signal SW1. The second shutter switch 231 turns on when the operation of the shutter button 101 is completed, so-called full-press (shooting instruction), and outputs a second shutter switch signal SW2. The system control unit 50 starts a series of shooting processes, from reading the signal from the imaging unit 211 to generating an image file containing the captured image and writing it to the recording medium 227, in response to the second shutter switch signal SW2.

[0033] The mode switch 103 switches the operating mode of the system control unit 50 to one of the following: still image shooting mode, video shooting mode, playback mode, etc. The still image shooting mode includes auto shooting mode, auto scene detection mode, manual mode, aperture priority mode (Av mode), shutter speed priority mode (Tv mode), and program AE mode (P mode). The still image shooting mode also includes various scene modes and custom modes, which are shooting settings for different shooting scenes. The user can directly switch to any of the above shooting modes using the mode switch 103. Alternatively, the user can use the mode switch After switching to the shooting mode list screen via switch 103, the user can selectively switch to any of the displayed modes using the control unit 228. Similarly, the video shooting mode may also include multiple modes.

[0034] The touch panel 109 is a touch sensor that detects various touch operations on the display surface of the display unit 108 (the operating surface of the touch panel 109). The touch panel 109 and the display unit 108 can be configured as an integrated unit. For example, the touch panel 109 is mounted on the upper layer of the display surface of the display unit 108 so that its light transmittance does not interfere with the display of the display unit 108. The input coordinates on the touch panel 109 are associated with the display coordinates on the display surface of the display unit 108. In this way, a GUI (Graphical User Interface) can be configured that makes it appear as if the user can directly operate the screen displayed on the display unit 108. The touch panel 109 can use any of the following methods: resistive, capacitive, surface acoustic wave, infrared, electromagnetic induction, image recognition, or optical sensor. Depending on the method, a touch may be detected when there is contact with the touch panel 109, or when a finger or pen approaches the touch panel 109. Either method is acceptable.

[0035] The system control unit 50 can detect the following operations or states on the touch panel 109. - A finger or pen that was not previously touching the touch panel 109 now touches the touch panel 109, i.e., the start of a touch (hereinafter referred to as Touch-Down). • The state in which the touch panel 109 is being touched with a finger or pen (hereinafter referred to as Touch-On). • The touch panel 109 is being moved while a finger or pen is touching it (hereinafter referred to as Touch-Move). The finger or pen that was touching the touch panel 109 is lifted (released), meaning the touch action ends (hereinafter referred to as "Touch-Up"). • The state in which nothing is being touched on the touch panel 109 (hereinafter referred to as Touch-Off).

[0036] When a touchdown is detected, a touch-on is also detected simultaneously. After a touchdown, touch-ons are usually detected continuously unless a touch-up is detected. Touch-ons are also detected simultaneously if a touch-move is detected. Even if a touch-on is detected, a touch-move will not be detected if the touch position has not moved. After all fingers or pens that were touching have been detected as having touched up, a touch-off occurs.

[0037] These operations and states, as well as the position coordinates of the finger or pen touching the touch panel 109, are notified to the system control unit 50 via the internal bus. Based on the notified information, the system control unit 50 determines what kind of operation (touch operation) was performed on the touch panel 109. For touch moves, the direction of movement of the finger or pen moving on the touch panel 109 can also be determined for each vertical and horizontal component on the touch panel 109 based on the change in position coordinates. If a touch move of a predetermined distance or more is detected, it is determined that a slide operation was performed. An operation in which a finger is touched on the touch panel 109 and then quickly moved a certain distance and then released is called a flick. In other words, a flick is an operation in which the finger is quickly traced across the touch panel 109 as if flicking it. If a touch move of a predetermined distance or more at a predetermined speed or faster is detected, and a touch-up is detected immediately afterward, it is determined that a flick was performed (it can be determined that a flick followed a slide operation). Furthermore, if multiple locations (for example, two points) are touched together (multitouch), and the touches of each other... A touch operation that brings two touch points closer together is called a pinch-in, and a touch operation that moves two touch points further apart is called a pinch-out. Pinch-out and pinch-in are collectively referred to as a pinch operation (or simply a pinch).

[0038] <Lens Unit Configuration> Figure 3 is a schematic diagram showing the configuration of the lens unit 300. Figure 3 shows the lens unit 300 attached to the camera 100. By attaching the lens unit 300, the camera 100 can capture a single image (still image or video) containing two image regions with a predetermined parallax. Note that, among the components of the camera 100 shown in Figure 3, the same reference numerals as those described in Figure 2 are used, and the descriptions of those components are omitted as appropriate.

[0039] The lens unit 300 is a type of interchangeable lens unit that can be attached to and removed from the camera 100. The lens unit 300 is a twin-lens unit capable of capturing parallax right and left images. The lens unit 300 has two optical systems (photographic lenses), and each of the two optical systems can capture a wide field of view of approximately 180 degrees. Specifically, each of the two optical systems of the lens unit 300 can capture a subject with a field of view (angle of view) of 180 degrees in the left-right direction (horizontal angle, azimuth angle, yaw angle) and 180 degrees in the up-down direction (vertical angle, elevation / depression angle, pitch angle). In other words, each of the two optical systems can capture an area of ​​the front hemisphere.

[0040] The lens unit 300 includes a right-eye optical system 301R having multiple lenses and a reflective mirror, a left-eye optical system 301L having multiple lenses and a reflective mirror, and a lens system control circuit 303. The right-eye optical system 301R has a lens 302R positioned on the subject side, and the left-eye optical system 301L has a lens 302L positioned on the subject side. Lenses 302R and 302L face the same direction, and their optical axes are approximately parallel. Each of the right-eye optical system 301R and the left-eye optical system 301L has a fisheye lens and forms a circular optical image on the imaging unit 211. The optical image formed via the right-eye optical system 301R (right image) and the optical image formed via the left-eye optical system 301L (left image) are imaged onto the imaging plane of one imaging unit 211, and the imaging unit 211 acquires a single image that includes the image regions of each optical image.

[0041] The lens unit 300 is a two-lens lens unit (VR180 lens unit) for obtaining VR180 images, which are one of the VR (Virtual Reality) image formats that enable binocular stereoscopic viewing. The lens unit 300 has a fisheye lens capable of capturing a range of approximately 180 degrees in both the right eye optical system 301R and the left eye optical system 301L. However, the range that can be captured by the lenses in each of the right eye optical system 301R and the left eye optical system 301L may be narrower than 180 degrees, around 160 degrees. The lens unit 300 can image the right image formed via the right eye optical system 301R and the left image formed via the left eye optical system 301L onto one or two image sensors of the camera to which the lens unit 300 is attached. In camera 100, the right image and the left image are imaged on a single image sensor, generating a single image (binacular image) with the right image region corresponding to the right image and the left image region corresponding to the left image side by side. The binaural image includes the right image region, the left image region, and a region that does not correspond to the optical image (non-image region, e.g., black region).

[0042] The lens unit 300 is attached to the camera 100 via the lens mount portion 304 and the camera mount portion 305 of the camera 100. In this way, the system control unit 50 of the camera 100 and the lens system control circuit 303 of the lens unit 300 are electrically connected via the communication terminal 124 of the camera 100 and the communication terminal 306 of the lens unit 300.

[0043] In Figure 3, the right image formed via the right-eye optical system 301R and the left image formed via the left-eye optical system 301L are imaged side by side on the imaging unit 211 of the camera 100. That is, the right-eye optical system 301R and the left-eye optical system 301L each image two optical images in two regions of a single image sensor. The imaging unit 211 converts the imaged subject (optical signal) into an analog electrical signal. By using the lens unit 300 (right-eye optical system 301R and left-eye optical system 301L) in this way, it is possible to acquire a single image (a binocular image) that includes two image regions with parallax. By dividing the acquired image into an image for the left eye and an image for the right eye and displaying them in VR, the user can view a three-dimensional VR image with a range of approximately 180 degrees. In other words, the user can view a VR180 image in 3D.

[0044] Here, a VR image is an image that can be displayed in VR, as described later. VR images include omnidirectional images (spherical images) captured by an omnidirectional camera (spherical camera), and panoramic images with a wider image range (effective image range) than the display range that can be displayed at once on the display unit. Furthermore, VR images are not limited to still images, but also include videos and live images (images acquired from the camera in near real-time). A VR image has an image range (effective image range) of up to 360 degrees horizontally and 360 degrees vertically. In addition, VR images also include images with a wider field of view than that that can be captured by a normal camera, or an image range that is wider than the display range that can be displayed at once on the display unit, even if the field of view is less than 360 degrees horizontally or vertically. Images captured by the camera 100 using the lens unit 300 described above are a type of VR image. VR images can be displayed in VR, for example, by setting the display mode of a display device (a display device that can display VR images) to "VR view". By displaying a portion of a VR image with a 360-degree field of view, users can move the displayed area by changing the orientation of the display device left or right (horizontal rotation direction), allowing them to view seamless, omnidirectional images in the left and right directions.

[0045] VR display (VR view) is a display method (display mode) that allows the display range to be changed, displaying images within a field of view that corresponds to the orientation of the display device. One type of VR display is "single-eye VR display (single-eye VR view)," which displays a single image by performing a transformation (distortion correction) that maps the VR image to a virtual sphere. Another type of VR display is "two-eye VR display (two-eye VR view)," which displays a VR image for the left eye and a VR image for the right eye side by side by performing a transformation that maps each to a virtual sphere. By performing "two-eye VR display" using VR images for the left eye and the right eye that have parallax with each other, it is possible to view these VR images in 3D. In any type of VR display, for example, when a user wears a display device such as an HMD (head-mounted display), the image displayed will correspond to the field of view that corresponds to the orientation of the user's face. For example, suppose that in a VR image, at a certain point in time, the image displayed will correspond to a field of view that is centered at 0 degrees horizontally (a specific direction, e.g., north) and 90 degrees vertically (90 degrees from the zenith, i.e., horizontal). If the orientation of the display device is reversed from this state (for example, changing the display surface from facing south to facing north), the display range of the same VR image will change to an image with a field of view centered on 180 degrees horizontally (opposite direction, e.g., south) and 90 degrees vertically. In other words, if the user, while wearing the HMD, turns their face from north to south (i.e., turns their back), the image displayed on the HMD will also change from a northern image to a southern image. Note that the VR image captured using the lens unit 300 is a VR180 image (180° image) that captures a range of approximately 180 degrees in front, and there is no image of a range of approximately 180 degrees behind. If such a VR180 image is displayed in VR and the orientation of the display device is changed to the side where there is no image, a blank area will be displayed.

[0046] By displaying VR images in VR in this way, users can visually experience the sensation (immersion) of being inside the VR image (in the VR space). Note that the method of displaying VR images is not limited to changing the orientation of the display device. For example, touch panels and directional buttons can also be used. The display range may be moved (scrolled) in response to user operations via a smartphone or other means. In addition, when displaying in VR (in the "VR View" display mode), the display range may be moved not only in response to changes in posture, but also in response to touch movements on the touch panel, drag operations with a mouse, or pressing of directional buttons. Note that a smartphone attached to VR goggles (head-mounted adapter) is a type of HMD.

[0047] Figure 4 illustrates a live view image 400 in a two-eye display. The live view image 400 includes a live view image region 401R corresponding to the live view image captured via the right eye optical system 301R, and a live view image region 401L corresponding to the live view image captured via the left eye optical system 301L. Both the live view image region 401R and the live view image region 401L are circular, and the captured subject is distorted more as it approaches the outer edge of the circle.

[0048] The dual-lens display makes it clear that two wide-field images are being captured by two optical systems, making it easy for the user to recognize that the camera 100 is equipped with a VR180 lens unit and is capturing VR images. On the other hand, because the dual-lens display shows two image areas on one screen, the subject appears smaller than when only one image area is displayed. For this reason, the dual-lens display is not suitable when the user is using functions such as touch AF or touch AF, which allow the user to select the subject by touching the live view screen.

[0049] In this embodiment, when the camera 100 receives a predetermined operation from the user during dual-lens display, it displays an enlarged image area, which is a magnified portion of the other image area, instead of the image area of ​​the other. Therefore, the camera 100 can display an image suitable for use with functions that involve subject selection.

[0050] The predetermined operation is, for example, an operation on an operating member assigned the function of displaying an enlarged image area. Alternatively, the predetermined operation may be a pinch-out operation on the live view image area 401R or the live view image area 401L.

[0051] Referring to Figure 5, the process by which the camera 100 displays a magnified live view image will be described. Figure 5 is a flowchart illustrating the magnification process of the camera 100 according to Embodiment 1. The magnification process shown in Figure 5 is realized by the system control unit 50 loading a program recorded in the non-volatile memory 219 into the system memory 218 and executing it. The magnification process shown in Figure 5 is started when the camera 100 is set to still image shooting mode or video shooting mode, and is repeatedly executed at predetermined time intervals until the mode is changed to a mode other than still image shooting mode or video shooting mode.

[0052] In step S501, the system control unit 50 acquires information on the type of lens unit attached to the camera 100 and determines whether or not a twin-lens unit 300 is attached. In the following description, the twin-lens unit 300 is assumed to be a lens unit for VR180.

[0053] The system control unit 50 can obtain information about the type of lens unit from the lens unit attached to the camera 100 by communicating with the lens unit via communication terminals 124, 206, and 306. If the camera 100 is fitted with a VR180 lens unit, the process proceeds to step S502. If the camera 100 is not fitted with a lens unit, or if a single-lens reflex lens unit is fitted, the process proceeds to step S507.

[0054] In step S502, the system control unit 50 activates the reference eye magnification mode. The reference eye magnification mode displays an enlarged image area, which is a portion of the image area corresponding to the reference eye (hereinafter also referred to as the reference eye image area) among the two-lens displayed image areas, in place of the other image area. This is the display mode. The reference eye live view image displayed in the reference eye image area is used as input for various functions such as AF processing and AE processing, and it is pre-set whether the right eye or the left eye is used as the reference eye. The user can also change whether the right eye or the left eye is used as the reference eye. The reference eye is set assuming it is the reference eye of the viewer who will be viewing the captured image.

[0055] Specifically, enabling the reference eye magnification mode involves ungraying the menu item on the camera's menu screen that allows you to assign the on / off toggle operation of the reference eye magnification mode to the magnification button 113. Once the reference eye magnification mode is enabled, the user can configure the reference eye magnification mode.

[0056] Furthermore, if the operation to switch the magnification mode on and off is assigned to a button other than the magnification button 113 (a function-assigned button), the system control unit 50 will control the system so that the magnification mode is not turned on when the reference eye magnification mode is enabled. In other words, the system control unit 50 will control the system so that the reference eye magnification mode and the magnification mode are not turned on at the same time.

[0057] In step S503, the system control unit 50 acquires two live view image areas captured by the imaging unit 211 via the VR180 lens unit and displays the two-lens image on the display unit 108. The two-lens image is an image formed by placing the live view image area 401R and the live view image area 401L side by side.

[0058] In step S504, the system control unit 50 (reception means) determines whether or not a magnification operation has been performed by the user to instruct the display of the live view image area in an enlarged manner. A magnification operation corresponds to a predetermined operation. Specifically, a magnification operation is the operation of pressing the magnification button 113, which is assigned to the operation of switching the reference eye magnification mode on and off, or the operation of pressing another function-assigned button, which is assigned to the operation of switching the reference eye magnification mode on and off.

[0059] The zoom operation may also be a pinch-out operation on the touch panel 109. The pinch-out operation may be an operation on the reference eye image area or an operation on the image area corresponding to an eye other than the reference eye (hereinafter also referred to as the non-reference eye image area). That is, even if the system control unit 50 detects a pinch-out operation on the non-reference eye image area, it proceeds to step S505 and displays the enlarged image area, which is a part of the reference eye image area, together with the reference eye image area.

[0060] If the system control unit 50 detects a zoom operation, it determines that the user has performed a zoom operation on the live view image area and proceeds to step S505. If the system control unit 50 does not detect a zoom operation, it determines that the user did not perform a zoom operation and terminates the zoom display process shown in Figure 5.

[0061] In step S505, the system control unit 50 generates an enlarged image area by enlarging a portion of the reference image area, which is one of the two live view image areas acquired in step S503. The live view image displayed in the reference image area is the image that serves as input for various functions such as AF processing and AE processing. In the reference image area, the range of the area to be enlarged is indicated by being surrounded by an enlargement frame.

[0062] In step S506, the system control unit 50 displays side by side the reference eye image region corresponding to the reference eye and the enlarged image region generated in step S505, from the two live view images acquired in step S503. That is, the system control unit 50 controls the system to display the enlarged image region instead of the non-reference eye image region that was displayed side by side with the reference eye image region.

[0063] The display of an enlarged image area allows users to easily select a subject by touching the enlarged image area. Furthermore, when the enlarged image area is displayed, users can also select a subject by touching the reference image area.

[0064] Referring to Figures 6(A) to 6(D), an example of displaying the reference image area and the enlarged image area will be explained. Figure 6(A) shows an example of displaying a rectangular enlarged image area 601L, which is cut out and enlarged from the reference image area 601R to match the shape of the display unit 108, alongside the reference image area 601R. The live view image 600 includes the reference image area 601R acquired in step S503 and the enlarged image area 601L generated in step S505. The enlarged image area 601L is an image area that is an enlargement of the area enclosed by the enlargement frame 602 displayed in the reference image area 601R.

[0065] The magnified frame 602 is a frame that indicates the area displayed in the magnified image area 601L within the reference image area 601R. When the reference image area 601R and the magnified image area 601L are displayed side by side, the magnified frame 602 is displayed superimposed on the reference image area 601R.

[0066] For each of the reference eye image region 601R and the enlarged image region 601L, an item (guide 603R and guide 603L) indicating whether the image was acquired by the left-eye optical system or the right-eye optical system may be displayed. Guides 603R and 603L may be displayed adjacent to the reference eye image region 601R, as in the case of guide 603R, or superimposed on the enlarged image region 601L, as in the case of guide 603L. In the example in Figure 6(A), the reference eye image region 601R was acquired by the right-eye optical system, so guide 603R displays "R". Also, since the enlarged image region 601L is an enlarged version of the reference eye image region 601R acquired by the right-eye optical system, guide 603L displays "R".

[0067] When the reference image area 601R and the enlarged image area 601L are displayed, touch operations for selecting a subject using functions such as touch AF or touch AE can be accepted in either image area.

[0068] When the reference image area 601R and the enlarged image area 601L are displayed side by side, if a pinch-out or pinch-in operation is performed on the touch panel 109, the system control unit 50 may change the magnification ratio of the enlarged image area 601L. When the magnification ratio of the enlarged image area 601L is changed, the system control unit 50 changes the size and position of the magnification frame 602 to indicate the imaging range of the enlarged image area 601L, and superimposes the magnification frame 602 onto the reference image area 601R. The pinch-out and pinch-in operations may be performed on either the reference image area 601R or the enlarged image area 601L.

[0069] Note that the shape and size of the magnification frame 602 are not limited to the example in Figure 6(A). The shape of the magnification frame 602 may be, for example, an ellipse that encloses the area corresponding to the magnified image region 601L. Also, the size of the magnification frame 602 can be changed according to the magnification ratio of the magnified image region 601L.

[0070] Figure 6(B) shows an example of displaying an enlarged image region 604L, which is an enlarged area enclosed by a square-shaped enlargement frame 605, alongside the reference image region 601R. The enlarged image region 604L is generated with the same shape as the enlargement frame 605. When the enlarged image region 604L is displayed in place of the non-reference image region, the areas excluding the reference image region 601R and the enlarged image region 604L are shown in a display format such as black.

[0071] Figure 6(C) shows an example of displaying various information on the OSD (On-Screen Display) in addition to the same display as in Figure 6(A). OSD display 606 includes information unrelated to subject selection operations, such as f-number, gain, and shutter speed, and is displayed superimposed on the reference image area 601R. On the other hand, OSD display 607 includes information related to subject selection operations, such as AF frame, AE frame, and tracking frame, and is displayed superimposed on the enlarged image area 601L. By superimposing only OSD display 607 related to subject selection operations onto the enlarged image area 601L, the user can eliminate information unnecessary for subject selection operations from their field of view and concentrate on the operation.

[0072] Figure 6(D) shows an example of displaying the enlarged image area 601L and the reference image area 601R side by side vertically when the display area of ​​the live view image is vertically oriented. When displaying a live view image captured by camera 100 on a remote terminal such as a smartphone, the display area may be vertically oriented. When the display area is vertically oriented, displaying the reference image area 601R and the enlarged image area 601L side by side horizontally will result in a smaller display than when they are displayed vertically, making it difficult for the user to select a subject.

[0073] Therefore, in a camera 100 or smartphone with a vertically oriented display area, it is preferable to display the reference image area 601R and the enlarged image area 601L side by side vertically, as shown in the live view image 608 in Figure 6(D). In this way, the system control unit 50 switches whether to display the reference image area 601R and the enlarged image area 601L side by side vertically or side by side horizontally, based on the aspect ratio of the display unit 108.

[0074] In step S507 of Figure 5, the system control unit 50 disables the reference eye magnification mode. Specifically, disabling the reference eye magnification mode involves graying out the menu item on the camera's menu screen that assigns the operation of switching the reference eye magnification mode on and off to the magnification button 113. When the reference eye magnification mode is disabled, it can be controlled so that the reference eye magnification mode is not set.

[0075] The display of the magnified image area 601L is canceled by pressing an operating component such as the magnification button 113, which is assigned the function of displaying the magnified image area. The display of the magnified image area 601L is also canceled when the assignment of the function of displaying the magnified image area to the magnification button 113, etc. is canceled, when the reference eye magnification mode is disabled, etc. When the display of the magnified image area 601L is canceled, the system control unit 50 displays a binocular image including the reference eye image area and the non-reference eye image area.

[0076] In step S508, the system control unit 50 acquires the live view image captured by the imaging unit 211 via the single-lens unit and displays the live view on the display unit 108.

[0077] In step S509, the system control unit 50 determines whether or not the user has performed a magnification operation to instruct the user to enlarge the live view image. Specifically, when a single-lens unit is attached, the magnification operation is the operation of pressing the magnification button 113. Alternatively, the magnification operation may be a pinch-out operation on the touch panel 109. If the system control unit 50 detects a magnification operation, it determines that the user has performed a magnification operation on the live view image area and proceeds to step S510. If the system control unit 50 does not detect a magnification operation, it determines that the user has not performed a magnification operation and terminates the magnification display process shown in Figure 5.

[0078] In step S510, the system control unit 50 displays an enlarged portion of the live view image acquired in step S508.

[0079] In Embodiment 1, when the camera 100 receives a predetermined operation from the user during dual-lens display, it displays the reference image area and an enlarged image area, which is a magnified portion of the reference image area, side by side. This makes it easier for the user to select a subject in the enlarged image area, even with a limited display area. Furthermore, by superimposing an enlarged frame indicating the area corresponding to the enlarged image area onto the reference image area, the user can easily determine where the enlarged image area is located within the entire imaging range. In this way, the camera 100 can display images suitable for use with functions that involve subject selection.

[0080] [Embodiment 2] In Embodiment 1, when the camera 100 receives a magnification operation from the user instructing it to enlarge the image, it displays the reference image area and the enlarged image area side by side. In contrast, in Embodiment 2, the camera 100 displays the reference image area and the enlarged image area side by side when a function involving subject selection, such as touch AF or touch AE, is enabled. In Embodiment 2, the predetermined operation is the operation to enable a function involving subject selection. The configuration of the camera 100 and the display examples of the live view image described in Figures 1 to 4 are the same as in Embodiment 1, so their description is omitted.

[0081] Figure 7 is a flowchart illustrating the magnification process of the camera 100 according to Embodiment 2. The magnification process shown in Figure 7 is started when the camera 100 is set to still image shooting mode or video shooting mode, and is repeatedly executed at predetermined time intervals until it is changed to a mode other than still image shooting mode or video shooting mode. The processes in steps S701 to S703 are the same as steps S501 to S503 of Embodiment 1.

[0082] In step S704, the system control unit 50 determines whether a function involving subject selection, such as touch AF or touch AE, is set to ON. If a function involving subject selection is set to ON, the process proceeds to step S705. If a function involving subject selection is not set to ON, the process shown in Figure 7 ends.

[0083] The processing in steps S705 to S710 is the same as the processing in steps S505 to S510 of Embodiment 1. The display of the enlarged image area is canceled when the function involving subject selection is turned off, and the system control unit 50 displays a binocular image including the reference eye image area and the non-reference eye image area.

[0084] In Embodiment 2, when a function involving subject selection, such as touch AF and touch AE, is turned on, the camera 100 displays the reference image area and the enlarged image area side by side. Therefore, by turning on a function involving subject selection, the user can display the enlarged image area without performing any additional operations.
