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 an instruction to start and stop video recording. The external viewfinder display 107 displays various settings such as shutter speed and aperture.

[0014] Camera 100 has a display unit 108, a touch panel 109, directional 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 on its back. The display unit 108 displays images and various information. The touch panel 109 is an operating member that detects touch operations on the display surface (touch operation surface) of the display unit 108. The directional keys 110 is an operating unit consisting of keys that can be pressed up, down, left, and right (four directional keys). Processing can be performed according to the position where the directional keys 110 are pressed. The SET button 111 is an operating member that is mainly pressed when confirming a selection item. The AE lock button 112 is an operating member that is pressed when fixing the exposure state in shooting standby mode. The zoom button 113 is an operating member that switches the zoom mode on and off in the live view display (LV display) of the shooting mode. When the magnification mode is on, the live view image (LV image) can be enlarged or reduced by operating the main electronic dial 104. The magnification button 113 is used in playback mode to enlarge the playback image or increase the magnification ratio. The playback button 114 is an operating element for switching between shooting mode and playback mode. By pressing the playback button 114 in shooting mode, the camera switches to playback mode, and the latest image recorded on the recording medium 227 (described later) can be displayed on the display unit 108.

[0015] The menu button 115 is an operating element that is pressed to display a menu screen on the display unit 108 that allows for various settings. The user can intuitively make various settings using the menu screen displayed on the display unit 108 and the directional keys 110 and SET button 111. The eyepiece section 116 is the part that the user looks through when looking into the eyepiece viewfinder (peep-in type viewfinder) 117. The user can access the EV inside the camera 100, which will be described later, through the eyepiece section 116. The image displayed on the F217 (Electronic View Finder) can be viewed. The eyepiece detection unit 118 is a sensor that detects whether or not the user is looking into the eyepiece unit 116 (eyepiece finder 117).

[0016] The touch bar 119 is a linear touch operation member (line touch sensor) capable of receiving 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 portion 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 is operable in a state (photographing posture) where one looks into the eyepiece 116 through the viewfinder 117 and can always press the shutter button 101. The touch bar 119 can receive a tap operation (an operation of touching and releasing without moving the touch position within a predetermined period) on the touch bar 119, 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 multifunction bar (M-Fn bar) to which various functions can be assigned.

[0017] In addition, the camera 100 has a grip portion 120, a thumb rest portion 121, a terminal cover 122, a lid 123, a communication terminal 124, a display switching button 125, and the like. The grip portion 120 is a holding portion formed in a shape that is easy to hold with the right hand when the user holds the camera 100. With the grip portion 120 held by the little finger, ring finger, and middle finger of the right hand, the shutter button 101 and the main electronic dial 104 are arranged at positions operable by the index finger of the right hand. Also, in the same state, the sub-electronic dial 105 and the touch bar 119 are arranged at positions operable by the thumb of the right hand. The thumb rest portion 121 (thumb standby position) is a grip portion provided on the back side of the camera 100 at a location where it is easy to place the thumb of the right hand that is holding the grip portion 120 without operating any operation members. The thumb rest portion 121 is composed of a rubber member or the like for enhancing the holding force (grip feeling). The terminal cover 122 protects connectors such as connection cables for connecting the camera 100 to an external device (external apparatus). The lid 123 protects the recording medium 227 and the slot by closing the slot for storing the recording medium 227 described later. The communication terminal 124 is a terminal for communicating with the lens unit (such as the lens unit 200 and the lens unit 300 described later) that is detachable from the camera 100. The display switching button 125 is an operation member for switching the display of the display unit 108 and the like.

[0018] FIG. 2 is a block diagram showing an example of the configuration of the camera 100. In FIG. 2, the same components as those in FIGS. 1(A) and 1(B) are denoted by the same reference numerals as in FIGS. 1(A) and 1(B), and the description of those components is omitted as appropriate. In FIG. 2, the lens unit 200 is attached to the camera 100.

[0019] First, let's describe the lens unit 200. The lens unit 200 is a type of interchangeable lens unit (interchangeable lens) that can be attached to and removed from the camera 100. The lens unit 200 is a single-lens reflex lens unit (single-lens reflex) 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, and the like.

[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 based on instructions from the system control unit 50, which will be described later. It controls the AF drive circuit 204, etc. 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, communication takes place via the communication terminal 206 of the lens unit 200 and the communication terminal 124 of the camera 100. The communication terminal 206 is the 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 that 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 (such as pixel interpolation, resizing, and color conversion) 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. This processing enables TTL (through-the-lens) AF processing, AE (automatic exposure) processing, EF (flash pre-flash) processing, etc. 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, which has been A / D 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 for display, thereby performing live view display.

[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 controls the memory 215, the D / A converter 216, and the display unit 10 8. Display control is also performed by controlling the EVF217 and other components.

[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, as well as programs read from the non-volatile memory 219. The non-volatile memory 219 is 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. 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. Furthermore, 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 is an attitude detection sensor that detects the attitude of the camera 100 relative to the direction of gravity. Based on the attitude detected by the attitude detection unit 222, it is possible to 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. For example, an acceleration sensor or a gyro sensor can be used for the attitude detection unit 222. It is also possible to detect the movement of the camera 100 (pan, tilt, lift, whether it is stationary or not, etc.) using the attitude detection unit 222.

[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 distance from the eyepiece unit 116 to the object can be determined by 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 eye (object) to the eyepiece unit 116. When an object is detected approaching the eyepiece unit 116 within a predetermined distance from a non-eyepiece state (non-approach state), it is detected that the eye has been caught in the eye. On the other hand, if the object that was detected as approaching moves beyond a predetermined distance from the eyepiece state (close-up state), it is detected that the eye has been removed. The threshold for detecting eyepiece contact and the threshold for detecting eye removal may be different, for example, by providing hysteresis. After eyepiece contact is detected, the eyepiece state is maintained until eye removal is detected. After eye removal is detected, the non-eyepiece state is maintained until eyepiece contact is detected again. The system control unit 50 switches the display (display state) / non-display (non-display state) of the display unit 108 and EVF 217 according to the state detected by the eyepiece detection unit 118. Specifically, at least in the shooting standby state and when the display destination switching setting is set to automatic switching, when the eyepiece is not in use, the display destination is set to the display unit 108 and the display is turned on, and the EVF 217 is hidden. When eyepiece contact is made, the display destination is set to the EVF 217 and the display is turned on, and the display unit 108 is hidden. Furthermore, the eyepiece detection unit 118 is not limited to an infrared proximity sensor; other sensors capable of detecting a state that can be considered as eyepiece use may be used in the eyepiece detection unit 118.

[0029] Furthermore, the camera 100 includes a viewfinder external display unit 107 and a viewfinder external display drive circuit 223. It includes 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 powered, 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 a shutter button 101, a power switch 102, a mode switch 103, a touch panel 109, and other operation units 229. Other operation units 229 include a main electronic dial 104, a sub electronic dial 105, a video button 106, a directional key 110, a SET button 111, an AE lock button 112, and other operation units 229. Other operation units 229 also include a zoom button 113, a playback button 114, a menu button 115, a touch bar 119, and a display switching button 125.

[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. In response to the 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. 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. In response to the 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.

[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, or playback mode. The modes included in still image shooting mode are 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). There are also various scene modes and custom modes that provide 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 switch to the shooting mode list screen using the mode switch 103, and then selectively switch to any of the displayed modes using the operation 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 light transmittance of the touch panel 109 is such that the light transmittance of the display unit 108 is such that The touch panel 109 is mounted on the upper layer of the display surface of the display unit 108 so as not to obstruct the display of 8. By associating the input coordinates on the touch panel 109 with the display coordinates on the display surface of the display unit 108, 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, but either method is acceptable.

[0035] Figure 3(A) is a schematic diagram showing an example of the configuration of the lens unit 300. Figure 3(A) shows the lens unit 300 attached to the camera 100. In Figure 3(A), components identical to those described in Figure 2 are denoted by the same reference numerals as in Figure 2, and their descriptions are omitted as appropriate.

[0036] 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 (two-lens system) capable of capturing parallax right and left images. The lens unit 300 has two optical systems, 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.

[0037] The lens unit 300 includes a right optical system 301R having multiple lenses and a reflective mirror, a left optical system 301L having multiple lenses and a reflective mirror, and a lens system control circuit 303. The right optical system 301R has a lens 302R positioned on the subject side, and the left 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.

[0038] 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 optical system 301R and the left optical system 301L. However, the range that can be captured by the lenses of the right optical system 301R and the left 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 optical system 301R and the left image formed via the left 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 onto a single image sensor, and a single image (binacular image) is generated in which the right image region (the region of the right image) and the left image region (the region of the left image) are arranged side by side.

[0039] The lens unit 300 has an adjustment mode change switch 304. The user can activate either the focus adjustment mode or the difference in focus adjustment mode by switching the position of the adjustment mode change switch 304 between positions 310 and 311 as shown in Figure 3(B). When the adjustment mode change switch 304 is at position 310, the focus adjustment mode is activated, and when the adjustment mode change switch 304 is at position 311, the difference in focus adjustment mode is activated.

[0040] The lens unit 300 is attached to the camera 100 via the lens mount portion 305 and the camera mount portion 306 of the camera 100. This allows the camera 100 to communicate 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 terminal 124 and the communication terminal 307 of the lens unit 300.

[0041] In Figure 3(A), the right image formed via the right optical system 301R and the left image formed via the left optical system 301L are imaged side by side on the imaging unit 211 of the camera 100. That is, the right optical system 301R and the left optical system 301L each image two optical images (subject images) in two regions of a single image sensor (imaging sensor). The imaging unit 211 converts the imaged optical images (light signals) into analog electrical signals. By using the lens unit 300 in this way, one image containing two image regions with parallax can be acquired from two locations (optical systems), the right optical system 301R and the left optical system 301L. 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 the VR180 image in 3D.

[0042] As shown in Figure 3(C), the lens unit 300 has a focus ring 320 for adjusting the focus. The focus ring 320 is exposed on the outer circumference of the lens unit 300, and the user can adjust the focus by rotating the focus ring 320. Depending on the adjustment mode of the lens unit 300, the focus adjustment is performed by driving one or both of the right optical system 301R and the left optical system 301L.

[0043] Figure 4 is a flowchart illustrating an example of the operation of camera 100. This operation is achieved 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 operation in Figure 4 is performed when camera 100 is in a shooting standby state. For example, when camera 100 is started in shooting mode or when shooting mode is set for camera 100, the operation in Figure 4 begins.

[0044] In S401, the system control unit 50 displays the right image region captured via the right optical system 301R and the left image region captured via the left optical system 301L on the display unit 108 in a fisheye format. Figure 5(A) shows an example of the displayed image (display screen) in S401. The right image region is inverted vertically and horizontally and imaged onto the right half of the imaging plane of the imaging unit 211, and the left image region is inverted vertically and horizontally and imaged onto the left half of the imaging plane of the imaging unit 211. The resulting image is then inverted vertically and horizontally and displayed on the display unit 108. Therefore, in Figure 5(A), the right image region 501 is located on the left side and the left image region 502 is located on the right side.

[0045] In S402, the system control unit 50 executes focus adjustment processing (processing related to focus adjustment). Details of the focus adjustment processing will be described later with reference to Figure 6.

[0046] In S403, the system control unit 50 determines whether or not an adjustment mode change operation has been performed. If the system control unit 50 determines that an adjustment mode change operation has been performed, it proceeds to S404; otherwise, it proceeds to S405. An adjustment mode change operation is, for example, an operation to switch the position of the adjustment mode change switch 304.

[0047] In S404, the system control unit 50 changes the adjustment mode.

[0048] In S405, the system control unit 50 determines whether to terminate the shooting standby state (display of the shooting standby screen, shooting mode). If the system control unit 50 determines to terminate the shooting standby state, it terminates the operation shown in Figure 4; otherwise, it proceeds to S406.

[0049] In S406, the system control unit 50 determines whether or not display switching operation A has been performed. If the system control unit 50 determines that display switching operation A has been performed, it proceeds to S407; otherwise, it proceeds to S401. Display switching operation A is, for example, the operation of touching the enlarged touch button 503 shown in Figure 5(A).

[0050] In S407, the system control unit 50 enlarges and displays the right image area on the display unit 108. Figure 5(B) shows an example of the displayed image (display screen) in S407. In Figure 5(B), the right image area is enlarged. In Figure 5(B), the enlarged image of the right image area is displayed, which is an image obtained by perspective projection transformation of a part of the right image area in a fisheye format. In Figure 5(B), the left image area is not displayed.

[0051] In S408, the system control unit 50 performs a focus adjustment process. Details of the focus adjustment process will be described later with reference to Figure 6.

[0052] In S409, the system control unit 50 determines whether or not an adjustment mode change operation has been performed. If the system control unit 50 determines that an adjustment mode change operation has been performed, it proceeds to S410; otherwise, it proceeds to S411.

[0053] In S410, the system control unit 50 changes the adjustment mode.

[0054] In S411, the system control unit 50 determines whether or not display switching operation A has been performed. If the system control unit 50 determines that display switching operation A has been performed, it proceeds to S401; otherwise, it proceeds to S412. Display switching operation A is, for example, the operation of touching the enlarged touch button 504 shown in Figure 5(B).

[0055] In S412, the system control unit 50 determines whether or not display switching operation B has been performed. If the system control unit 50 determines that display switching operation B has been performed, it proceeds to S413; otherwise, it proceeds to S407. Display switching operation B is, for example, the operation of pressing the display switching button 125.

[0056] In S413, the system control unit 50 enlarges and displays the left image area on the display unit 108. Figure 5(C) shows an example of the displayed image (display screen) in S413. In Figure 5(C), the left image area is enlarged. In Figure 5(C), the enlarged image of the left image area is displayed, which is an image obtained by perspective projection transformation of a part of the left image area in a fisheye format. In Figure 5(C), the right image area is not displayed.

[0057] In S414, the system control unit 50 displays warning guide A on the display unit 108. Figure 5(D) shows an example of warning guide A. The warning guide A in Figure 5(D) is a guide indicating that while the left image area is being magnified, both the focus adjustment of the right optical system 301R and the focus adjustment of the left optical system 301L are performed in accordance with the rotation of the focus ring 320. The focus adjustment of the right optical system 301R is performed by driving the right optical system 301R, and the focus adjustment of the left optical system 301L is performed by driving the left optical system 301L.

[0058] Now, let's consider the case where only the focus of the right optical system 301R is adjusted in response to the rotation of the focus ring 320. For example, the user rotates the focus ring 320 while comparing the right and left image regions, changing only the focus position of the right optical system 301R so that the same subject is in focus in both the right and left image regions.

[0059] However, the display unit 108 of the camera 100 is small, and when both the right and left image areas are displayed, it is difficult to see the details of the right and left image areas (such as the degree of focus). It can be difficult to confirm this easily. Therefore, users may see not only both the right and left image areas displayed, but also a portion of the right image area enlarged to fill the entire screen, and a portion of the left image area enlarged to fill the entire screen.

[0060] Furthermore, when a portion of the left image area is enlarged to fill the entire screen (the right image area is not displayed), the user cannot see the right image area, making it unlikely that the user would want to adjust the focus of only the right optical system 301R. In such a state, for example, the user might want to adjust the focus of both the right optical system 301R and the left optical system 301L, or they might want to adjust the focus of only the left optical system 301L.

[0061] Therefore, in a configuration where only the focus adjustment of the right optical system 301R is performed in response to the rotation of the focus ring 320, unintended focus adjustments may occur.

[0062] Therefore, in this embodiment, as shown in Figure 8, in the focus difference adjustment mode, the focus adjustment is changed depending on whether the right image area is being displayed or not (whether the left image area is being magnified or not). To suppress user confusion caused by such changes in focus adjustment, a warning guide A is displayed.

[0063] Warning Guide A is displayed when the left image area is enlarged, and may be hidden after a predetermined time has elapsed since the start of displaying Warning Guide A. Warning Guide A may also be hidden in response to user actions such as touching. In Figure 5(D), Warning Guide A is text, but other items such as icons may be displayed as Warning Guide A.

[0064] Returning to the explanation of Figure 4, in S415, the system control unit 50 performs a focus adjustment process. Details of the focus adjustment process will be described later using Figure 6.

[0065] In S416, the system control unit 50 determines whether or not an adjustment mode change operation has been performed. If the system control unit 50 determines that an adjustment mode change operation has been performed, it proceeds to S417; otherwise, it proceeds to S418.

[0066] In S417, the system control unit 50 changes the adjustment mode.

[0067] In S418, the system control unit 50 determines whether or not display switching operation A has been performed. If the system control unit 50 determines that display switching operation A has been performed, it proceeds to S401; otherwise, it proceeds to S419. Display switching operation A is, for example, the operation of touching the enlarged touch button 505 shown in Figure 5(C).

[0068] In S419, the system control unit 50 determines whether or not display switching operation B has been performed. If the system control unit 50 determines that display switching operation B has been performed, it proceeds to S407; otherwise, it proceeds to S413. Display switching operation B is, for example, the operation of pressing the display switching button 125.

[0069] Figure 6 is a flowchart showing an example of the focus adjustment process performed in steps S402, S408, and S415 of Figure 4.

[0070] In S601, the system control unit 50 determines whether or not the MF peaking display function has been turned ON. If the system control unit 50 determines that the MF peaking display function has been turned ON, it proceeds to S602; otherwise, it proceeds to S603.

[0071] In S602, the system control unit 50 sets the MF peaking display function to ON (enabled). The MF peaking display function is a function that performs MF peaking display. MF peaking display is a display related to the focus position of the optical system, and as shown in Figure 5(E), it is a display that emphasizes the contour of the in-focus area. In MF peaking display, the contour may be emphasized by superimposing contour lines (another image) on the captured image, or by changing the pixel values ​​of the captured image. The contour is emphasized with a predetermined color, such as red or green.

[0072] In S603, the system control unit 50 determines whether or not the MF indicator display function has been turned ON. If the system control unit 50 determines that the MF indicator display function has been turned ON, it proceeds to S604; otherwise, it proceeds to S605.

[0073] In S604, the system control unit 50 sets the MF indicator display function to ON (enabled). The MF indicator display function is a function that displays the MF indicator. The MF indicator display is an indication of the focus position of the optical system, and as shown in Figure 5(F), it is an indication of an item (MF indicator) that shows the distance from the camera 100 to the focus position of the optical system. The MF indicator is superimposed on the captured image.

[0074] In S605, the system control unit 50 determines whether or not the focus guide display function has been turned ON. If the system control unit 50 determines that the focus guide display function has been turned ON, it proceeds to S606; otherwise, it proceeds to S607.

[0075] In S606, the system control unit 50 sets the focus guide display function to ON (enabled). The focus guide display function is a function that displays the focus guide. The focus guide display is a display related to the focal position of the optical system, and as shown in Figure 5(G), it is a display of items (focus guides) that indicate the direction of movement of the focal position of the optical system in order to focus on the subject. The focus guide is superimposed on the captured image. In Figure 5(G), the focus guide includes three triangles and one guide frame. The focus guide can take on multiple display forms, as shown in Figure 7. Depending on the display form of the focus guide, the direction and amount of movement of the focal position in order to focus on the subject at the guide frame position are indicated.

[0076] In S607, the system control unit 50 determines whether the adjustment mode (the currently set adjustment mode) is the focus difference adjustment mode. If the system control unit 50 determines that the adjustment mode is the focus difference adjustment mode, it proceeds to S608; otherwise, it proceeds to S611. The determination in S607 is, for example, whether the adjustment mode change switch 304 is in position 311.

[0077] In S608, the system control unit 50 determines whether both the right image area and the left image area are displayed in fisheye format. If the system control unit 50 determines that both the right image area and the left image area are displayed in fisheye format, it proceeds to S611; otherwise, it proceeds to S609.

[0078] In S609, the system control unit 50 determines whether or not the right image area is being displayed in an enlarged view. If the system control unit 50 determines that the right image area is being displayed in an enlarged view, it proceeds to S614; otherwise, it proceeds to S610. The determination in S609 may also be interpreted as determining whether or not the right image area is displayed but the left image area is not.

[0079] In S610, the system control unit 50 determines whether or not the left image area is being enlarged. The system control unit 50 determines whether the left image area is being displayed in an enlarged view, and proceeds to S617 if it determines that the left image area is being displayed; otherwise, it terminates the focus adjustment process. The determination in S610 may also be interpreted as determining whether the left image area is displayed but the right image area is not.

[0080] Subsequently, as shown in S611, S612, S614, S615, S617, and S618, the system control unit 50 performs different focus adjustment processes depending on the adjustment mode and display state. Figure 8 shows the correspondence between the combination of adjustment mode and display state and the focus adjustment process.

[0081] In S611, the system control unit 50 determines whether or not the focus ring 320 has been rotated (whether or not a focus adjustment instruction has been given). If the system control unit 50 determines that the focus ring 320 has been rotated, it proceeds to S612; otherwise, it proceeds to S613.

[0082] In S612, the system control unit 50 drives both the right optical system 301R and the left optical system 301L to adjust the focus of both the right optical system 301R and the left optical system 301L. Here, the amount and direction of change in focus position are determined by the amount and direction of rotation of the focus ring 320. For example, the larger the amount of rotation of the focus ring 320, the larger the amount of change in focus position. Also, whether the focus position changes towards infinity or near depends on whether the focus ring 320 is rotated clockwise or counterclockwise. The system control unit 50 moves the focus position of the right optical system 301R and the focus position of the left optical system 301L in the same direction and by the same amount of movement.

[0083] In S613, the system control unit 50 displays whichever of the MF peaking display and MF indicator display is enabled. If the MF peaking display is enabled, the MF peaking display corresponding to the right image area and the MF peaking display corresponding to the left image area are displayed. If the MF indicator display is enabled, the MF indicator display corresponding to the right image area and the MF indicator display corresponding to the left image area are displayed.

[0084] In the MF peaking display corresponding to the right image area, the contour of the in-focus area in the right image area is emphasized, and in the MF peaking display corresponding to the left image area, the contour of the in-focus area in the left image area is emphasized. In the MF indicator display corresponding to the right image area, an item indicating the distance from camera 100 to the focus position of the right optical system 301R is displayed, and an item indicating the distance from camera 100 to the focus position of the left optical system 301L is displayed.

[0085] However, if the right image region is not displayed, the MF peaking display and MF indicator display corresponding to the right image region will not be performed. Similarly, if the left image region is not displayed, the MF peaking display and MF indicator display corresponding to the left image region will not be performed.

[0086] In S614, the system control unit 50 determines whether or not the focus ring 320 has been rotated (whether or not a focus adjustment instruction has been given). If the system control unit 50 determines that the focus ring 320 has been rotated, it proceeds to S615; otherwise, it proceeds to S616.

[0087] In S615, the system control unit 50 adjusts the focus of the right optical system 301R without adjusting the focus of the left optical system 301L. For example, the system control unit 50 adjusts only the right optical system 301R without driving the left optical system 301L (without moving the focus position of the left optical system 301L). By driving the right optical system 301R, only the focus position of the right optical system 301R is moved. The system control unit 50 may drive both the right optical system 301R and the left optical system 301L to move the focus position of the right optical system 301R and the focus position of the left optical system 301L in the same direction and by the same amount of movement. After that, the system control unit 50 may drive only the left optical system 301L in the reverse direction to return the focus position of the left optical system 301L to its original position. Alternatively, the focus adjustment of the right optical system 301R may be performed by other means.

[0088] In S616, the system control unit 50 displays whichever of the MF peaking display and MF indicator display is enabled. If the MF peaking display is enabled, the MF peaking display corresponding to the left image area is not performed, and the MF peaking display corresponding to the right image area is performed. If the MF indicator display is enabled, the MF indicator display corresponding to the left image area is not performed, and the MF indicator display corresponding to the right image area is performed. However, if the right image area is not displayed, neither the MF peaking display corresponding to the right image area nor the MF indicator display corresponding to the right image area is performed.

[0089] In S617, the system control unit 50 determines whether or not the focus ring 320 has been rotated (whether or not a focus adjustment instruction has been given). If the system control unit 50 determines that the focus ring 320 has been rotated, it proceeds to S618; otherwise, it proceeds to S619.

[0090] In S618, similar to S612, the system control unit 50 performs both the focus adjustment of the right optical system 301R and the focus adjustment of the left optical system 301L. Simultaneously with, before, or after the focus adjustment, the system control unit 50 may display warning guide A on the display unit 108. As described above, warning guide A is displayed to prevent user confusion.

[0091] In S619, the system control unit 50 displays whichever of the MF peaking display and MF indicator display is enabled. If the MF peaking display is enabled, the MF peaking display corresponding to the right image area is not performed, and the MF peaking display corresponding to the left image area is performed. If the MF indicator display is enabled, the MF indicator display corresponding to the right image area is not performed, and the MF indicator display corresponding to the left image area is performed. However, if the left image area is not displayed, neither the MF peaking display corresponding to the left image area nor the MF indicator display corresponding to the left image area is performed.

[0092] In S620, the system control unit 50 determines whether both the right and left image regions are displayed in fisheye format. If the system control unit 50 determines that both the right and left image regions are displayed in fisheye format, it proceeds to S622; otherwise, it proceeds to S621. If the focus guide display is disabled, the system control unit 50 may terminate the focus adjustment process without proceeding to either S621 or S622.

[0093] In S621, the system control unit 50 displays a focus guide in the displayed image area. If the right image area is displayed, the focus guide is displayed in the right image area; if the left image area is displayed, the focus guide is displayed in the left image area. The display position of the focus guide frame is specified, for example, by a user touching the display unit 108.

[0094] In S622, the system control unit 50 focuses on one of the right image region and the left image region. The focus guide is displayed. For example, if a position in the right image area is specified by the user's touch operation, the focus guide is displayed at that specified position (position in the right image area). Similarly, if a position in the left image area is specified by the user's touch operation, the focus guide is displayed at that specified position (position in the left image area). The method for determining the image area on which the focus guide is displayed is not limited to this; for example, the focus guide may always be displayed in the right image area regardless of whether the position specified by the user is in the right or left image area. In this case, if a position in the left image area is specified by the user's touch operation, the guide frame of the focus guide may be displayed at the position in the right image area corresponding to that specified position (touch position). The image area on which the focus guide is displayed may be selected according to the adjustment mode. In focus difference adjustment mode, the focus guide may be displayed in the right image area regardless of the touch position, and in focus adjustment mode, the focus guide may be displayed in the image area including the touch position.

[0095] Alternatively, instead of processing S617 and S618, you may perform processing S623 and S624, or processing S625 and S626.

[0096] In S623, the system control unit 50 determines whether or not the focus ring 320 has been rotated (whether or not a focus adjustment instruction has been given). If the system control unit 50 determines that the focus ring 320 has been rotated, it proceeds to S624; otherwise, it proceeds to S619.

[0097] In S624, the system control unit 50 adjusts the focus of the left optical system 301L without adjusting the focus of the right optical system 301R. As explained in S615, various methods can be used to adjust the focus of only one of the optical systems.

[0098] Processing S623 and S624 is performed while the right image area is not displayed and the left image area is enlarged. Performing processing S623 and S624 prevents the focus position of the right optical system 301R (the optical system whose image area is not displayed) from moving to an unintended focus position.

[0099] When performing the processes S623 and S624, only the focus adjustment of the left optical system 301L may be performed, and a warning guide B may be displayed on the display unit 108. Figure 5(H) shows an example of a warning guide B. The warning guide B in Figure 5(H) is a guide that indicates that when either the right image area or the left image area is magnified, only the focus adjustment of the optical system corresponding to the displayed image area will be performed in accordance with the rotation of the focus ring 320. This makes it possible to inform the user that, for example, the focus adjustment changes depending on whether both the right and left image areas are displayed or only one of them is displayed.

[0100] In S625, the system control unit 50 determines whether or not the focus ring 320 has been rotated (whether or not a focus adjustment instruction has been given). If the system control unit 50 determines that the focus ring 320 has been rotated, it proceeds to S626; otherwise, it proceeds to S619.

[0101] In S626, the system control unit 50 displays a warning guide C on the display unit 108 without performing focus adjustment on either the right optical system 301R or the left optical system 301L. Figure 5(I) shows an example of a warning guide C. The warning guide C is an item that corresponds to the fact that neither the right optical system 301R nor the left optical system 301L is focused. The warning guide C in Figure 5(I) indicates that focusing is not possible and prompts the user to switch to a magnified display of the right image area.

[0102] Furthermore, when performing the processes in S625 and S626, the system control unit 50 terminates the focus adjustment process without performing the processes in S619 to S622.

[0103] By performing the S625 and S626 processes, even if it is not possible to adjust the focus of the left optical system 301L, it is possible to prevent the focus position of the right optical system 301R (the optical system where the image area is not displayed) from moving to an unintended focus position.

[0104] As described above, this embodiment makes it possible to suppress unintended focus adjustments by the user. For example, it is possible to suppress situations in which only the focus position of the right optical system 301R changes when the right image area is not displayed.

[0105] In the above explanation, the situation described as "no focus adjustment" is simply a situation where focus adjustment is suppressed compared to the situation described as "focus adjustment is performed," and the focus position may be moved by a smaller amount than in the situation described as "focus adjustment is performed." The situation described as "no focus position movement" is simply a situation where focus position movement is suppressed compared to the situation described as "focus position movement," and the focus position may be moved by a smaller amount than in the situation described as "focus position movement." For example, in S615, the focus position of the left optical system 301L may be moved a small amount, and the focus position of the right optical system 301R may be moved a large amount. In S626, at least one of the focus positions of the right optical system 301R and the left optical system 301L may be moved slightly.

[0106] 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.

[0107] 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).

[0108] 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.

[0109] For example, the right optical system 301R and the right image region in the above description may be replaced with the left optical system 301L and the left image region, and the left optical system 301L and the left image region in the above description may be replaced with the right optical system 301R and the right image region. Two optical systems arranged in directions other than left and right (up and down or diagonally) or three or more optical systems may be used.

[0110] Other display states may exist besides the three states listed above: a state where both the right and left image regions are displayed in fisheye format, a state where the right image region is magnified, and a state where the left image region is magnified.

[0111] For example, as shown in Figure 5(J), there may be a parallel magnification display state in which a left magnified area, which is an enlarged portion of the left image area, and a right magnified area, which is an enlarged portion of the right image area, are displayed side by side. The display state may transition to the parallel magnification state in response to a touch on a touch button other than the magnification touch button 503. In the focus difference adjustment mode, if the parallel magnification display state is in place, the process proceeds to, for example, S611.

[0112] As shown in Figure 5(K), a right-two-window display state may exist in which the fisheye-format right image area and the right magnified area are displayed side by side. User operations for transitioning to each display state are not particularly limited, and user operations for transitioning to the right-two-window display state are also not particularly limited. In focus difference adjustment mode, if the right-two-window display state is in place, proceed to, for example, S614. Similarly, a left-two-window display state may exist.

[0113] In the above explanation, "fisheye format" may be replaced with other formats such as "equirectangular format."

[0114] A state in which both the right and left image regions are displayed in fisheye format may be interpreted as a state in which both the right and left image regions are displayed. A state in which the right image region is enlarged may be interpreted as a state in which the right image region is displayed but the left image region is not. A state in which the left image region is enlarged may be interpreted as a state in which the left image region is displayed but the right image region is not.

[0115] In S608, the system control unit 50 may proceed to S614 if it determines that both the right and left image regions are displayed in fisheye format. This allows the user to adjust the focus difference while comparing the right and left image regions on the same screen. By selecting the focus adjustment mode with the adjustment mode change switch 304, both the focus adjustment of the right optical system 301R and the focus adjustment of the left optical system 301L can be performed simultaneously.

[0116] The display of the optical system's focus position is not limited to MF peaking display, MF indicator display, and focus guide display. One type of display, two types of displays, or four or more types of displays may be provided for the optical system's focus position.

[0117] User operation for adjusting focus is not limited to rotating the focus ring 320. For example, user operation for adjusting focus may be a touch operation (such as a swipe) on the screen of a smartphone or other device wirelessly connected to the camera 100. User operation for adjusting focus may also be a keyboard operation on a personal computer wirelessly connected to the camera 100.

[0118] The adjustment modes are not limited to focus adjustment mode and difference in focus adjustment mode. There may be three or more adjustment modes. For example, as shown in Figure 9, there may be a focus adjustment mode, a right focus adjustment mode, and a left focus adjustment mode.

[0119] Furthermore, although an example of applying the present invention to a digital camera has been described, the present invention is not limited to digital cameras and can be applied to any electronic device capable of acquiring captured images. For example, the present invention can be applied to personal computers and PDAs, mobile phone terminals and portable image viewers, printers, digital photo frames, music players, game consoles, e-book readers, etc. The present invention can also be applied to video players, display devices (including projection devices), tablet terminals, smartphones, AI speakers, home appliances, and in-vehicle devices. Yes, this invention is applicable to imaging devices as well as to external equipment for imaging devices.

[0120] <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.
