Description

[Technical Field]

[0001] The present invention relates to an imaging device, a control method thereof, and a program. [Background technology]

[0002] In cameras with interchangeable lenses, where the lens barrel extends from the camera body toward the subject, the photographer typically holds the lens barrel with their left hand. Because the left hand is constantly in contact with the lens barrel when holding the camera in this manner, the lens barrel is often equipped with a ring that allows the user to perform certain operations. One example of this type of ring is a focus ring, which allows the user to manually control the focus.

[0003] However, since it is difficult to mount multiple rings on the lens barrel of small or inexpensive lenses, a dual-purpose ring that can be switched between a focus ring and a ring for operations other than manual focus is sometimes installed.

[0004] However, when a camera is equipped with a dual-purpose ring, there is a combination in which the dual-purpose ring is set to operate as a ring for operations other than manual focus and the focus mode is set to manual focus. This combination makes it impossible to use the dual-purpose ring to quickly focus from an out-of-focus state. To focus, it is necessary to either switch the dual-purpose ring to operate as a focus ring or switch the focus mode to autofocus. However, with compact or inexpensive lenses, it is difficult to incorporate switches on the lens barrel for switching the dual-purpose ring or focus mode. As a result, these switches must be made from, for example, a settings menu on the camera body, which requires the user to change their posture while holding the camera, thereby compromising operability. In this way, the combination of dual-purpose ring settings and focus mode can be cumbersome.

[0005] Patent Document 1 discloses a camera that can switch between autofocus and manual focus, and in the manual focus state, the focal position of the lens can be moved by turning an MF adjustment dial. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-3121 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the camera disclosed in Patent Document 1 cannot eliminate the inconvenience caused by combining the settings of the dual-purpose ring with the focus mode. The present invention has been made in view of the above-mentioned points, and has as its object to eliminate the inconvenience caused by combining the setting of a dual-purpose operating member with a focus mode. [Means for solving the problem]

[0008] The present invention is an imaging device whose focus mode can be set to autofocus, which automatically focuses on a subject, or manual focus, which manually focuses on a subject, and is characterized by having a control means that controls a dual-purpose operating member, which can be switched between operating as a first operating member for manual focus operation or as a second operating member for operations other than manual focus operation, to operate as the first operating member when the focus mode is manual focus. [Effects of the Invention]

[0009] According to the present invention, it is possible to eliminate the hassle caused by combining the setting of a dual-purpose operation member with a focus mode. [Brief explanation of the drawings]

[0011] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First Embodiment 1(a) and (b) show external views of a digital camera (hereinafter simply referred to as camera) 100 as an example of an imaging device to which the present invention is applied. FIG. 1(a) is a front perspective view of the camera 100, and FIG. 1(b) is a rear perspective view of the camera 100. A lens unit 150 (see FIG. 2), which will be described later, is detachable from the camera 100. The camera 100 is an imaging device whose focus mode can be set to either autofocus, which automatically focuses on a subject, or manual focus, which manually focuses on a subject.

[0012] Display unit 28 is a display unit provided on the back of camera 100, and displays images and various information. Touch panel 70a detects touch operations on the display surface (touch operation surface) of display unit 28. Outside viewfinder display unit 43 is a display unit provided on the top surface of camera 100, and displays various setting values ​​such as shutter speed and aperture. Shutter button 61 is an operation member for issuing shooting instructions. Mode selector switch 60 is an operation member for switching between various modes. Terminal cover 40 is a cover that protects a connector (not shown) for connecting a connection cable or the like that connects camera 100 to an external device.

[0013] The main electronic dial 71 is a rotary operation member used to change settings such as shutter speed and aperture. The power switch 72 is an operation member used to turn the power of the camera 100 on and off. The sub electronic dial 73 is a rotary operation member used to move the selection frame (cursor) and advance through images. The cross key 74 is configured so that the up, down, left, and right portions can be pressed, and a process corresponding to the pressed portion is executed. The SET button 75 is an operation member used mainly to confirm a selection. The video button 76 is an operation member used to start or stop video shooting (recording). The M-Fn button 77 is an operation member used to quickly change various settings such as white balance and ISO sensitivity by pressing it in shooting standby mode. During calibration, the M-Fn button 77 can also be used to confirm the viewpoint. The playback button 79 is an operation member used to switch between shooting mode and playback mode. By pressing the playback button 79 during shooting mode, the camera switches to playback mode, and the most recent image recorded on the recording medium 200 (described later) can be displayed on the display unit 28. The menu button 81 is an operating member for performing an instruction operation to display a menu screen. By pressing the menu button 81, a menu screen on which various settings can be made is displayed on the display unit 28. The user can intuitively make various settings using the menu screen displayed on the display unit 28, the cross key 74, and the SET button 75.

[0014] The communication terminal 10 is a communication terminal through which the camera 100 communicates with the lens unit 150. The eyepiece 16 is the eyepiece of an eyepiece finder (a peer-type finder), and the user can view an image displayed on an internal EVF 29 (Electronic View Finder) through the eyepiece 16. The eyepiece detection unit 57 is composed of an eyepiece detection sensor that detects whether the user (photographer) has placed their eye on the eyepiece 16. The lid 202 is a lid for a slot that stores a recording medium 200. The grip unit 90 is a holding unit shaped to be easily held in the user's right hand when holding the camera 100. When the camera 100 is held by gripping the grip unit 90 with the little finger, ring finger, and middle finger of the right hand, the shutter button 61 and the main electronic dial 71 are located at positions that can be operated with the index finger of the right hand. Furthermore, when the grip unit 90 is held in the right hand, the sub electronic dial 73 is located at a position that can be operated with the thumb of the right hand.

[0015] 2 is a block diagram showing an example of the configuration of the camera 100 and the lens unit 150. Note that the same components as those shown in FIG. 1 are denoted by the same reference numerals. The lens unit 150 is detachably attached to the camera 100. The lens unit 150 includes an aperture 1, a lens 103, an aperture drive circuit 2, an AF drive circuit 3, a lens system control circuit 4, and a communication terminal 6. The lens 103 is usually composed of multiple lenses, but for simplicity, only a single lens is shown here. The communication terminal 6 is a communication terminal that enables the lens unit 150 to communicate with the camera 100. The lens unit 150 communicates with the system control unit 50 via the communication terminals 6 and 10. In the lens unit 150, the aperture 1 is controlled by the lens system control circuit 4 via the aperture drive circuit 2. In addition, in the lens unit 150, the lens system control circuit 4 adjusts the focus by displacing the position of the lens 103 via the AF drive circuit 3.

[0016] As shown in FIG. 7(a), the lens barrel of the lens unit 150 is equipped with an AF / MF switch 152, an F / C combined ring (focus / control combined ring) 155, and an F / C switch (focus / control changeover switch) 153. The AF / MF switch 152 is a focus mode setting unit, and is a switch for switching the focus mode between AF (autofocus) and MF (manual focus). The user can select AF or MF by switching the position of the AF / MF switch 152. When the focus mode is AF, the lens 103 is displaced via the AF drive circuit 3 to achieve focus. When the focus mode is MF, the lens 103 is displaced by the user's MF operation.

[0017] The F / C combined ring 155 is a combined operating member that can be switched between operating as a focus ring or as a control ring. The F / C combined ring 155 can be rotated around the optical axis of the lens barrel. Here, the focus ring is a ring that enables manual focus operation. In this embodiment, the focus ring corresponds to an example of a first operating member for manual focus operation. Also, the control ring is a ring to which a desired function (shutter speed setting, aperture setting, ISO sensitivity setting, etc.) can be assigned, allowing the user to operate the camera settings. In this embodiment, the control ring corresponds to an example of a second operating member for operations other than manual focus operation.

[0018] The F / C switch 153 is a switch for switching whether the F / C combined ring 155 operates as a focus ring or as a control ring. The F / C switch 153 is a switch with two positions: F (focus) and C (control). By switching the F / C switch 153, the user can switch and set whether the F / C combined ring 155 operates as a focus ring or as a control ring. In this embodiment, the F / C switch 153 corresponds to an example of a predetermined operation unit. There are a variety of combinations of switches and rings on the lens barrel, examples of which will be described later with reference to FIG.

[0019] The shutter 101 is a focal plane shutter that can freely control the exposure time of the imaging unit 22 under the control of the system control unit 50. The imaging unit 22 includes an imaging element (image sensor) configured by a CCD, CMOS element, or the like that converts an optical image into an electrical signal. The A / D converter 23 converts the analog signal output from the imaging unit 22 into a digital signal. The image processing unit 24 performs predetermined processing (pixel interpolation, resizing such as reduction, color conversion, etc.) on data from the A / D converter 23 or data from the memory control unit 15. The image processing unit 24 also performs predetermined arithmetic processing using the captured image data, and the system control unit 50 performs exposure control and distance measurement control based on the arithmetic results obtained by the image processing unit 24. This allows TTL (through-the-lens) AF processing, AE (auto exposure) processing, EF (flash pre-flash) processing, etc. to be performed. The image processing unit 24 also performs predetermined arithmetic processing using the captured image data, and performs TTL AWB (auto white balance) processing based on the arithmetic results obtained.

[0020] The memory control unit 15 controls data transmission and reception between the A / D converter 23, the image processing unit 24, and the memory 32. Output data from the A / D converter 23 is written to the memory 32 via the image processing unit 24 and the memory control unit 15, or via the memory control unit 15 without via the image processing unit 24. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23, as well as image data to be displayed on the display unit 28 and the EVF 29. The memory 32 has a storage capacity sufficient to store a predetermined number of still images and a predetermined period of moving images and audio. The memory 32 also serves as a memory for image display (video memory). The display image data written to the memory 32 is displayed on the display unit 28 and the EVF 29 via the memory control unit 15. The display unit 28 and the EVF 29 display images on displays such as LCDs and organic EL displays in response to signals from the memory control unit 15. A live view display is performed by sequentially transferring and displaying the digital signals that have been A / D converted by the A / D converter 23 and stored in the memory 32 on the display unit 28 or the EVF 29. An image displayed in live view is called a live view image. Various setting values ​​such as shutter speed and aperture are displayed on the viewfinder external display 43 via a viewfinder external display drive circuit 44 .

[0021] The nonvolatile memory 56 is an electrically erasable and recordable memory, and may be, for example, a Flash-ROM, etc. Constants, programs, etc. for the operation of the system control unit 50 are stored in the nonvolatile memory 56. The system control unit 50 is a control unit consisting of at least one processor or circuit, and controls the entire camera 100. The system control unit 50 performs various processes, which will be described later, by executing programs stored in the nonvolatile memory 56. The system control unit 50 also performs display control by controlling the memory 32, the display unit 28, etc. The system memory 52 is, for example, a RAM. The system control unit 50 loads into the system memory 52 constants and variables for the operation of the system control unit 50, programs read from the nonvolatile memory 56, and the like. The system timer 53 is a timekeeping unit that measures the time used for various controls and the time of a built-in clock.

[0022] The power supply control unit 80 is composed of a battery detection circuit, a DC-DC converter, a switch circuit for switching between powered blocks, etc., and detects whether a battery is installed, the type of battery, and the remaining battery power. The power supply control unit 80 also controls the DC-DC converter based on the detection results and instructions from the system control unit 50, and supplies the required voltage for the required period to each unit including the recording medium 200. The power supply unit 30 is composed of primary batteries such as alkaline batteries or lithium batteries, secondary batteries such as NiCd batteries, NiMH batteries, or Li batteries, an AC adapter, etc. The I / F 18 is an interface with a recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording captured images, and is composed of a semiconductor memory, a magnetic disk, or the like.

[0023] The communication unit 54 transmits and receives video signals and audio signals to and from external devices connected wirelessly or via a wired cable. The communication unit 54 can also be connected to a wireless LAN (Local Area Network) or the Internet. The communication unit 54 can also communicate with external devices via Bluetooth (registered trademark) or Bluetooth Low Energy. The communication unit 54 can transmit images (including live view images) captured by the imaging unit 22 and images recorded on the recording medium 200, and can receive image data and various other information from external devices.

[0024] The orientation detection unit 55 detects the orientation of the camera 100 with respect to the direction of gravity. Based on the orientation detected by the orientation detection unit 55, it is possible to determine whether an image captured by the imaging unit 22 was captured with the camera 100 held horizontally or vertically. The system control unit 50 can add orientation information corresponding to the orientation detected by the orientation detection unit 55 to the image file of the image captured by the imaging unit 22, or rotate and record the image. An acceleration sensor, a gyro sensor, or the like can be used as the orientation detection unit 55. The acceleration sensor or gyro sensor of the orientation detection unit 55 can also be used to detect movement of the camera 100 (panning, tilting, lifting, whether or not it is stationary, etc.).

[0025] The eyepiece detection unit 57 is an eyepiece detection sensor that detects (approach detection) whether an eye (object) approaches (approach) or moves away (away) from the eyepiece 16 of the eyepiece finder 17. The system control unit 50 switches the display unit 28 and the EVF 29 between on (display state) and off (non-display state) depending on the state detected by the eyepiece detection unit 57. Specifically, at least in a shooting standby state and when the display destination switching setting is automatic switching, when the eye is not in contact with the camera, the display is turned on with the display unit 28 as the display destination and the EVF 29 is not displayed. When the eye is in contact with the camera, the display is turned on with the EVF 29 as the display destination and the display unit 28 is not displayed. For example, an infrared proximity sensor can be used as the eyepiece detection unit 57, and it can detect the approach of an object to the eyepiece 16 of the eyepiece finder 17 that incorporates the EVF 29. When an object approaches, infrared light emitted from a light-emitting section (not shown) of the eyepiece detection section 57 is reflected by the object and received by a light-receiving section (not shown) of the infrared proximity sensor. The amount of received infrared light can also be used to determine the distance the object has approached from the eyepiece 16 (eyepiece distance). In this way, the eyepiece detection section 57 performs eyepiece detection, detecting the proximity of the object to the eyepiece 16.

[0026] The mode selector switch 60 switches the operating mode of the system control unit 50 between a still image capture mode, a video capture mode, etc. Modes included in the still image capture mode include an auto capture mode, an auto scene determination mode, a manual focus (MF) mode, an aperture priority mode (Av mode), a shutter speed priority mode (Tv mode), and a program AE mode (P mode). There are also various scene modes and custom modes that provide capture settings for different capture scenes. The mode selector switch 60 allows the user to directly switch to one of these modes. Alternatively, the mode selector switch 60 may be used to switch to a list screen of capture modes, and then the user may select one of the displayed modes and switch using other operating members. Similarly, the video capture mode may also include multiple modes. The power switch 72 switches the power of the camera 100 on and off.

[0027] The operation unit 70 is an input unit that accepts user operations and is used to input various operational instructions to the system control unit 50. The operation unit 70 includes the shutter button 61, a touch panel 70a, a main electronic dial 71, a sub electronic dial 73, a cross key 74, a SET button 75, a video button 76, an M-Fn button 77, a playback button 79, a menu button 81, and the like.

[0028] The shutter button 61 includes a first shutter switch 62 and a second shutter switch 64. The first shutter switch 62 is turned ON when the shutter button 61 is pressed halfway (a shooting preparation command) and generates a first shutter switch signal SW1. The system control unit 50 starts shooting preparations such as AF processing, AE processing, AWB processing, and EF processing in response to the first shutter switch signal SW1. The second shutter switch 64 is turned ON when the shutter button 61 is pressed fully (a shooting command) and generates a second shutter switch signal SW2. The system control unit 50 starts a series of shooting processes, from reading out a signal from the imaging unit 22 to writing the captured image to the recording medium 200 as an image file, in response to the second shutter switch signal SW2.

[0029] The touch panel 70a is a touch sensor that detects various touch operations on the display surface of the display unit 28 (the operation surface of the touch panel 70a). The touch panel 70a and the display unit 28 can be configured as an integrated unit. For example, the touch panel 70a is configured so that its light transmittance does not interfere with the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. By associating input coordinates on the touch panel 70a with display coordinates on the display surface of the display unit 28, a GUI (graphical user interface) is realized that makes it appear as if the user can directly operate the screen displayed on the display unit 28.

[0030] Here, an example of the configuration of lens unit 150 will be described with reference to Fig. 7. One lens unit can be attached to camera 100, and any one of the multiple types of lens units described in Fig. 7 is attached. 7(a) to 7(f) are diagrams showing an example in which a combined F / C ring 155 is mounted on the lens barrel of the lens unit 150. Also, Fig. 7(g) is a diagram showing an example in which a focus ring 151 and a control ring 154 are mounted on the lens barrel of the lens unit 150, instead of the combined F / C ring 155.

[0031] The lens unit 150 in FIG. 7( a ) is equipped with an F / C combined ring 155 , an AF / MF switch 152 , and an F / C switch 153 . The lens unit 150 in FIG. 7(b) is equipped with an F / C combined ring 155 and an F / C switch 153, but is not equipped with an AF / MF switch 152. The lens unit 150 in FIG. 7(c) is equipped with an F / C combined ring 155 and an AF / MF switch 152, but is not equipped with an F / C switch 153. The lens unit 150 in FIG. 7(d) is equipped with an F / C combined ring 155, but is not equipped with an AF / MF switch 152 or an F / C switch 153.

[0032] The lens unit 150 in FIG. 7( e) is equipped with an F / C combination ring 155 and a three-value switch 156, but does not have an AF / MF switch 152 or an F / C switch 153. The three-value switch 156 has three positions: AF, MF, and C (control). The user can switch the F / C combination ring 155 and the focus mode by switching the three-value switch 156. When the position of the three-value switch 156 is set to AF, the F / C combination ring 155 operates as a focus ring, and the focus mode is AF. When the position of the three-value switch 156 is set to MF, the F / C combination ring 155 operates as a focus ring, and the focus mode is MF. When the position of the three-value switch 156 is set to C, the F / C combination ring 155 operates as a control ring, and the focus mode is the same as the setting of the camera 100. In this embodiment, the three-value switch 156 corresponds to an example of a predetermined operation unit.

[0033] The lens unit 150 of FIG. 7(f) is the lens unit 150 of FIG. 7(a) to which a control ring 154 has been added. Generally, control rings emit a sound or a tactile sensation with each click to notify the user of the change in the number of clicks. Focus rings, on the other hand, generally emit no sound or tactile sensation when operated. Therefore, it is possible to mount two rings on the lens barrel: a control ring and a focus ring. However, to satisfy the desire to operate the control ring silently during video recording, for example, a combined F / C ring 155 can be made to function as a control ring. While an example of adding a control ring 154 to the lens unit 150 of FIG. 7(a) has been described here, the lens units 150 of FIGS. 7(b) to 7(e) may also have configurations in which the control ring 154 is added.

[0034] The lens unit 150 in FIG. 7(g) is equipped with a focus ring 151, a control ring 154, and an AF / MF switch 152, but does not have an F / C combined ring 155.

[0035] Furthermore, if the lens barrel of the lens unit is not equipped with an F / C switch 153 or a ternary switch 156, the F / C combined ring 155 can be switched on the setting screen displayed on the camera 100. 6A to 6C are diagrams showing examples of various setting screens displayed on the camera 100. The setting screens of FIGS. 6A-1 to 6C-3, 6B, and 6C are displayed on the display unit 28, EVF 29, etc. of the camera 100. The user performs various settings using the touch panel 70a, main electronic dial 71, sub electronic dial 73, cross key 74, SET button 75, etc. Values ​​set on the setting screens are stored in the nonvolatile memory 56 of the camera 100.

[0036] FIG. 6(a)-1 is an example of a setting screen displayed on the camera 100, on which the F / C combined ring 155 can be switched. The setting screen displays setting items 601 and 602 that allow the user to select whether the F / C combined ring 155 operates as a focus ring or a control ring. The user can select either setting item 601 or 602. When setting item 601 is selected, the F / C combined ring 155 is set to operate as a focus ring, and when setting item 602 is selected, the F / C combined ring 155 is set to operate as a control ring. In this embodiment, the setting screen of FIG. 6(a)-1 corresponds to an example of a first setting unit. The setting screen of FIG. 6(a)-1 also displays a transition section 603 for transitioning to a detailed setting screen.

[0037] 6(a)-2 is an example of a detailed setting screen displayed on the camera 100 when the transition section 603 is selected. The detailed setting screen displays setting items 604 to 606. The user can select any one of the setting items 604 to 606. When the setting item 604 is selected, the focus mode is set to be fixed to AF when the F / C combined ring 155 is operated as a control ring. Note that when the selection of the setting item 604 is canceled, the setting fixed to AF is canceled. When the setting item 605 is selected, the F / C combined ring 155 is set to be fixed as a focus ring when the focus mode is set to manual focus. Note that when the selection of the setting item 605 is canceled, the setting to be fixed as a focus ring is canceled. When the setting item 606 is selected, the focus mode is not fixed to AF as when the setting item 604 is selected, and the F / C combined ring 155 is not fixed as a focus ring as when the setting item 605 is selected. In this embodiment, the setting screen of FIG. 6(a)-2 corresponds to an example of the second setting means.

[0038] Note that in the initial display (default settings), setting item 604 is selected. Therefore, when the F / C combination ring 155 is operated as a control ring, the focus mode is usually fixed to AF. On the other hand, if the lens unit is equipped with the F / C combination ring 155 but not with a focus ring, focus adjustment is not possible when the F / C combination ring 155 is operated as a control ring. Since focus adjustment is not possible even when the focus mode is MF, the focus mode is basically fixed to AF when the F / C combination ring 155 is operated as a control ring. However, the user can cancel the fixation to AF by intentionally selecting setting items 605 or 606 instead of setting item 604. However, in the initial display (initial setting), the setting item 605 may be selected instead of the setting item 604. In this case, when the focus mode is set to manual focus, the F / C combined ring 155 is fixed as a focus ring.

[0039] As shown in FIG. 8, the camera 100 may be equipped with an AF / MF switch 82. In this case, as shown in FIG. 6(c), the AF / MF switch 82 may be set to be enabled or disabled on a setting screen displayed on the camera 100. When set to enabled, the focus mode can be set with the AF / MF switch 82. On the other hand, when set to disabled, the AF / MF switch 82 does not affect the state of the camera 100, preventing accidental operation of the AF / MF switch 82. Although the AF / MF switch 82 is configured to be switched between enabled and disabled, it may also be configured to switch between a focus mode setting and a setting other than the focus mode. Furthermore, the AF / MF switch 82 may be configured to be customizable, or may not be disabled.

[0040] 6(b), instead of the AF / MF switch 82, the focus mode may be switched between AF and MF on a setting screen displayed on the camera 100. Note that this is not limited to switching to the AF / MF switch 82, and if the AF / MF switch 82 is provided but set to disabled, the focus mode may be switched between AF and MF on the setting screen.

[0041] Fig. 3 is a flowchart showing an example of processing executed by the camera 100 according to this embodiment. The flowchart in Fig. 3 is implemented by the system control unit 50 by loading a program stored in the non-volatile memory 56 into the system memory 52 and executing it. The flowchart in Fig. 3 is started when the camera 100 starts up or when the menu screen or playback screen is exited and the camera transitions to a shooting standby state in which a shooting standby screen is displayed.

[0042] In step S301, the system control unit 50 acquires data necessary for shooting, such as the AF mode, ISO, and white balance, from the non-volatile memory 56. The system control unit 50 also acquires data such as the shutter speed and aperture value calculated based on photometric information, etc. The system control unit 50 also acquires data such as the focal length and switch status held in the lens unit 150 via the communication terminals 6 and 10.

[0043] In step S302, the system control unit 50 tentatively determines whether the F / C combined ring 155 mounted on the lens unit 150 is to operate as a focus ring or as a control ring. The tentative operation determination process for the F / C combined ring in step S302 will be described later with reference to FIG.

[0044] In step S303, the system control unit 50 tentatively determines whether the focus mode should be AF or MF. The focus mode tentative determination process in step S303 will be described later with reference to FIG.

[0045] In step S304, the system controller 50 determines whether the F / C combination ring 155 mounted on the lens unit 150 is to operate as a focus ring or a control ring. The system controller 50 also determines whether the focus mode is to be AF or MF. The operation of the F / C combination ring and the focus mode determination process in step S304 will be described later with reference to FIG. 9.

[0046] In step S305, the system control unit 50 determines whether or not the F / C combined ring 155 has been operated. If the F / C combined ring 155 has been operated, the process proceeds to step S306. On the other hand, if the F / C combined ring 155 has not been operated, the process proceeds to step S308.

[0047] In step S306, the system control unit 50 determines whether the F / C combined ring 155 operates as a focus ring based on the operation determined in step S304 to be performed by the F / C combined ring 155. If the F / C combined ring 155 operates as a focus ring, the process proceeds to step S301. Here, when the focus mode is MF, the system control unit 50 executes focus movement processing in response to operation of the F / C combined ring 155. However, because the focus movement processing is controlled by closing the lens unit 150 side, the system control unit 50 does not execute the processing but instead instructs the lens system control circuit 4 to execute the focus movement processing. The lens system control circuit 4 executes the focus movement processing in the lens unit 150, and thus the focus movement processing is executed for the entire imaging device including the lens unit 150. Furthermore, when the focus mode is AF, the system control unit 50 may not execute the focus movement process even if the F / C combination ring 155 is operated, or may execute the focus movement process in response to the operation of the F / C combination ring 155. When the focus mode is AF, the system control unit 50 can change whether or not to execute the focus movement process based on a setting (not shown) in response to a user operation.

[0048] On the other hand, if the F / C combined ring 155 does not function as a focus ring, that is, if it functions as a control ring, the process proceeds to step S307. In step S307, the system controller 50 activates the function assigned to the control ring, and then the process proceeds to step S301.

[0049] 7(f), the lens unit 150 may be equipped with a combined F / C ring 155 and a control ring 154. In such a lens unit 150, when the combined F / C ring 155 is operated as a control ring, it is preferable that the control ring 154 not operate to prevent erroneous operation. Steps S308 to S310 will explain this process.

[0050] In step S308, the system controller 50 determines whether or not the control ring 154 mounted on the lens unit 150 has been operated. If the control ring 154 has been operated, the process proceeds to step S309. On the other hand, if the control ring 154 has not been operated, the process proceeds to step S311.

[0051] In step S309, the system control unit 50 determines whether the F / C combined ring 155 operates as a focus ring based on the operation determined in step S304 to be performed by the F / C combined ring 155. If the F / C combined ring 155 operates as a focus ring, the process proceeds to step S310. On the other hand, if the F / C combined ring 155 does not operate as a focus ring, that is, if it operates as a control ring, the process proceeds to step S301. In step S310, the system controller 50 activates the function assigned to the control ring 154, and then the process proceeds to step S301.

[0052] In step S311, the system controller 50 determines whether or not an operation to start AF processing has been performed, depending on whether or not the first shutter switch signal SW1 has been generated by half-pressing the shutter button 61. If an operation to start AF processing has been performed, the process proceeds to step S312. On the other hand, if an operation has not been performed, the process proceeds to step S314. In step S312, the system control unit 50 refers to the focus mode determined in step S304, and if it is autofocus, the process proceeds to step S313. On the other hand, if the focus mode is not autofocus, that is, if it is manual focus, the process proceeds to step S301. In step S313, the system controller 50 starts the AF process, and the process proceeds to step S301.

[0053] In step S314, the system controller 50 determines whether or not an operation to start shooting has been performed based on whether or not the second shutter switch signal SW2 has been generated by fully pressing the shutter button 61. If an operation to start shooting has been performed, the process proceeds to step S315. On the other hand, if an operation has not been performed, the process proceeds to step S316. In step S315, the system control unit 50 performs a photographing process, and the process proceeds to step S301. In step S316, the system control unit 50 performs processing according to the operation.

[0054] In step S317, the system control unit 50 determines whether or not an operation to end shooting has been performed. If an operation to end shooting has been performed, the process proceeds to step S318. On the other hand, if an operation to end shooting has not been performed, the process proceeds to step S301. In step S318, the system control unit 50 performs a shooting end process and ends the flowchart of FIG.

[0055] Next, the details of the F / C dual-purpose ring operation tentative decision process in step S302 of FIG. 3 will be described with reference to FIG. In step S401, the system control unit 50 determines whether or not the F / C combined ring 155 is present in the lens unit 150. If the F / C combined ring 155 is present, the process proceeds to step S402. Since the F / C combined ring 155 is present in the lens units 150 of FIGS. 7(a) to (f), the process proceeds to step S402. On the other hand, if the F / C combined ring 155 is not present, the flow chart of FIG. 4 ends. Since the F / C combined ring 155 is not present in the lens unit 150 of FIG. 7(g), the flow chart of FIG. 4 ends.

[0056] In step S402, the system control unit 50 determines whether or not the lens unit 150 has an F / C switch 153. If the F / C switch 153 is present, the process proceeds to step S403. Since the F / C switch 153 is present in the lens units 150 of FIGS. 7(a), (b), and (f), the process proceeds to step S403. On the other hand, if the F / C switch 153 is not present, the process proceeds to step S406. Since the F / C switch 153 is not present in the lens units 150 of FIGS. 7(c), (d), and (e), the process proceeds to step S406.

[0057] In step S403, the system control unit 50 determines whether the position of the F / C switch 153 is set to control. If the position of the F / C switch 153 is set to control, the process proceeds to step S404. On the other hand, if the position of the F / C switch 153 is not set to control, i.e., if it is set to focus, the process proceeds to step S405. In step S404, the system control unit 50 sets the F / C dual-purpose ring 155 to operate as a control ring, and then ends the flowchart of FIG. In step S405, the system controller 50 sets the F / C combined ring 155 to operate as a focus ring, and then ends the flow chart of FIG. In this way, in the lens unit 150 of FIGS. 7( a ), 7 ( b ), and 7 ( f ), the operation of the F / C combined ring 155 is in accordance with the position of the F / C switch 153 .

[0058] In step S406, the system control unit 50 determines whether or not the lens unit 150 has a ternary switch 156. If the ternary switch 156 is present, the process proceeds to step S407. Since the ternary switch 156 is present in the lens unit 150 of FIG. 7(e), the process proceeds to step S407. On the other hand, if the ternary switch 156 is not present, the process proceeds to step S410. Since the lens units 150 of FIGS. 7(c) and (d) do not have a ternary switch 156, the process proceeds to step S410.

[0059] In step S407, the system control unit 50 determines whether the position of the three-value switch 156 is set to control. If the position of the three-value switch 156 is set to control, the system control unit 50 proceeds to step S408. On the other hand, if the position of the three-value switch 156 is not set to control, that is, if the position is set to AF or MF, the system control unit 50 proceeds to step S409. In step S408, the system controller 50 sets the F / C dual-purpose ring 155 to operate as the control ring, and then ends the flowchart of FIG. In step S409, the system controller 50 sets the F / C combined ring 155 to operate as a focus ring, and then ends the flow chart of FIG. In this way, in the lens unit 150 of FIG. 7( e ), the operation of the F / C combined ring 155 is in accordance with the position of the three-state switch 156 .

[0060] 7(c) and 7(d), when the lens unit 150 does not have either the F / C switch 153 or the ternary switch 156, the operation of the F / C ring 155 is set on a setting screen displayed on the camera 100 as shown in FIG. 6(a)-1. Here, the setting on the setting screen displayed on the camera 100 for selecting whether the F / C ring 155 operates as a focus ring or a control ring is referred to as the F / C setting. When setting item 601 is selected in the F / C setting, the value of the F / C setting is stored as focus in the nonvolatile memory 56, and when setting item 602 is selected in the F / C setting, the value of the F / C setting is stored as control in the nonvolatile memory 56. In steps S410 to S413, the system control unit 50 performs processing using the value stored in the F / C setting.

[0061] In step S410, the system control unit 50 determines whether the F / C setting value stored in the nonvolatile memory 56 of the camera 100 is control. If the F / C setting value is control, the process proceeds to step S412. On the other hand, if the F / C setting value is not control, i.e., if it is focus, the process proceeds to step S411. In step S411, the system control unit 50 sets the F / C combined ring 155 to operate as a focus ring, and then ends the flow chart of FIG.

[0062] In step S412, the system controller 50 sets the F / C dual-purpose ring 155 to operate as a control ring. In step S413, the system control unit 50 sets an F / C combined ring determination process flag to be used in the operation of the F / C combined ring and the focus mode determination process, and ends the flowchart of Fig. 4. The operation of the F / C combined ring and the focus mode determination process will be described later with reference to Fig. 9. In this way, in the lens unit 150 of FIGS. 7(c) and 7(d), the operation of the F / C combined ring 155 is as set on the setting screen.

[0063] Next, the focus mode tentative determination process in step S303 of FIG. 3 will be described in detail with reference to FIG. In step S501, the system control unit 50 determines whether or not communication with the lens unit 150 is possible via the communication terminal 10. If communication with the lens unit 150 is possible, the process proceeds to step S503. On the other hand, if communication with the lens unit 150 is not possible, the process proceeds to step S502. The following states apply to the state in which the system control unit 50 is unable to communicate with the lens unit 150. Examples of states in which communication is not possible include when the lens unit 150 is not attached to the camera 100 or is not attached correctly, when the lens unit 150 is broken, or when the lens unit 150 does not support communication.

[0064] In step S502, the system controller 50 cannot communicate with the lens unit 150 and therefore cannot perform AF control, so it sets the focus mode to MF and ends the flowchart of FIG.

[0065] In step S503, the system control unit 50 determines whether or not the lens unit 150 has an AF / MF switch 152. If the AF / MF switch 152 is present, the process proceeds to step S504. The lens units 150 in FIGS. 7(a), (c), (f), and (g) have an AF / MF switch 152, so the process proceeds to step S504. On the other hand, if the AF / MF switch 152 is not present, the process proceeds to step S507. The lens units 150 in FIGS. 7(b), (d), and (e) do not have an AF / MF switch 152, so the process proceeds to step S507.

[0066] In step S504, the system control unit 50 determines whether the position of the AF / MF switch 152 is set to AF. If the position of the AF / MF switch 152 is set to AF, the process proceeds to step S505. On the other hand, if the position of the AF / MF switch 152 is not set to AF, that is, if it is set to MF, the process proceeds to step S506. In step S505, the system control unit 50 sets the focus mode to AF, and ends the flowchart of FIG. In step S506, the system control unit 50 sets the focus mode to MF, and ends the flowchart of FIG. In this way, in the lens units 150 of FIGS. 7(a), (c), (f), and (g), the focus mode is determined according to the position of the AF / MF switch 152.

[0067] In step S507, the system control unit 50 determines whether or not the lens unit 150 has a ternary switch 156. If the ternary switch 156 is present, the process proceeds to step S508. Since the ternary switch 156 is present in the lens unit 150 of FIG. 7(e), the process proceeds to step S508. On the other hand, if the ternary switch 156 is not present, the process proceeds to step S512. Since the ternary switch 156 is not present in the lens units 150 of FIGS. 7(b) and (d), the process proceeds to step S512.

[0068] In step S508, the system control unit 50 determines whether the position of the three-value switch 156 is set to AF. If the position of the three-value switch 156 is set to AF, the system control unit 50 proceeds to step S509. On the other hand, if the position of the three-value switch 156 is not set to AF, the system control unit 50 proceeds to step S510. In step S509, the system control unit 50 sets the focus mode to AF, and ends the flowchart of FIG.

[0069] In step S510, the system control unit 50 determines whether the position of the three-value switch 156 is set to MF. If the position of the three-value switch 156 is set to MF, the system control unit 50 proceeds to step S511. On the other hand, if the position of the three-value switch 156 is not set to MF, the system control unit 50 proceeds to step S512. In step S511, the system control unit 50 sets the focus mode to MF, and ends the flowchart of FIG.

[0070] 7(e), when the position of the ternary switch 156 is set to AF or MF, the focus mode is determined according to the position of the ternary switch 156. On the other hand, when the position of the ternary switch 156 is set to control, the process proceeds to step S512. In this way, when the lens unit 150 is equipped with the AF / MF switch 152 or the ternary switch 156, the focus mode is set by the AF / MF switch 152 or the ternary switch 156.

[0071] In step S512, the system control unit 50 determines whether or not the AF / MF switch 82 is present in the camera 100. If the AF / MF switch 82 is present as shown in Fig. 8, the process proceeds to step S513. On the other hand, if the AF / MF switch 82 is not present, the process proceeds to step S517. In step S513, the system control unit 50 determines whether the AF / MF switch 82 is enabled. As shown in FIG. 6(c), the AF / MF switch 82 can be set to enabled or disabled on the setting screen. If the AF / MF switch 82 is set to enabled, the process proceeds to step S514. If the AF / MF switch 82 is not set to enabled, that is, if it is set to disabled, the process proceeds to step S517.

[0072] In step S514, the system control unit 50 determines whether the position of the AF / MF switch 82 is set to AF. If the position of the AF / MF switch 82 is set to AF, the process proceeds to step S515. On the other hand, if the position of the AF / MF switch 82 is not set to AF, that is, if it is set to MF, the process proceeds to step S516. In step S515, the system control unit 50 sets the focus mode to AF, and ends the flow chart of FIG. In step S516, the system control unit 50 sets the focus mode to MF, and ends the flow chart of FIG.

[0073] In this way, when the lens unit 150 is not equipped with the AF / MF switch 152 or the ternary switch 156 and the AF / MF switch 82 is enabled, the focus mode is set by the AF / MF switch 82. Also, when the ternary switch 156 is present but the position of the ternary switch 156 is set to control, and the AF / MF switch 82 is enabled, the focus mode is set by the AF / MF switch 82.

[0074] In step S517, the system control unit 50 determines whether the value of the AF / MF setting stored in the nonvolatile memory 56 of the camera 100 is MF. Here, as shown in FIG. 6(b), the setting for selecting AF or MF on the setting screen displayed on the camera 100 is referred to as the AF / MF setting. The value selected in the AF / MF setting is stored in the nonvolatile memory 56. If the value of the AF / MF setting is not MF, that is, if it is AF, the process proceeds to step S518. On the other hand, if the value of the AF / MF setting is MF, the process proceeds to step S519. In step S518, the system control unit 50 sets the focus mode to AF in accordance with the AF / MF setting, and ends the flowchart of FIG.

[0075] In step S519, the system control unit 50 sets the focus mode to MF. In step S520, the system control unit 50 sets a focus mode determination process flag to be used in the operation of the F / C combined ring and the focus mode determination process, and ends the flowchart of Fig. 5. The operation of the F / C combined ring and the focus mode determination process will be described later with reference to Fig. 9.

[0076] Next, the operation of the F / C combined ring and the focus mode determination process in step S304 of FIG. 3 will be described in detail with reference to FIG. In step S901, the system control unit 50 determines whether or not the F / C dual-purpose ring determination process flag was set in step S413 of Fig. 4. If the flag is set, the process proceeds to step S902. On the other hand, if the flag is not set, the process proceeds to step S904. In step S902, the system control unit 50 determines whether or not a selection has been made to fix the F / C combination ring 155 as a focus ring during manual focus. Specifically, the system control unit 50 determines whether or not the setting item 605 for fixing as a focus ring has been selected on the setting screen in FIG. 6(a)-2. If a selection has been made to fix the F / C combination ring 155 as a focus ring, the process proceeds to step S903. On the other hand, if a selection has not been made to fix the F / C combination ring as a focus ring, the flow chart in FIG. 9 ends.

[0077] In step S903, the system control unit 50 sets the F / C combined ring 155 to operate as a focus ring, and ends the flowchart of Fig. 9. That is, the system control unit 50 controls the F / C combined ring 155 to operate as a focus ring regardless of the F / C setting.

[0078] In step S904, the system control unit 50 determines whether or not the focus mode determination process flag was set in step S520 of Fig. 5. If the flag is set, the process proceeds to S905. On the other hand, if the flag is not set, the process ends the flowchart of Fig. 9. In step S905, the system control unit 50 determines whether or not a selection has been made to fix to AF when using the F / C combined ring 155 as a control ring. Specifically, the system control unit 50 determines whether or not the setting item 604 for fixing to AF has been selected on the setting screen in FIG. 6(a)-2. If a selection has been made to fix to AF, the process proceeds to step S906. On the other hand, if a selection has not been made to fix to AF, the flow chart in FIG. 9 ends. In step S906, the system control unit 50 sets the focus mode to AF, and ends the flowchart of Fig. 9. That is, the system control unit 50 controls the focus mode to AF regardless of the focus mode setting in the AF / MF setting.

[0079] As described above, in this embodiment, when the focus mode is manual focus, the system control unit 50 controls the F / C combination ring 155 to operate as a focus ring. This control prevents a combination in which the focus mode is set to MF and the F / C combination ring 155 operates as a control ring. This avoids the inconvenience of being unable to quickly bring an out-of-focus image into focus using the F / C combination ring 155 even when the focus mode is MF. Furthermore, there is no need to switch the F / C combination ring 155 to operate as a focus ring or to switch the focus mode to AF, preventing a loss of operability. Therefore, the camera 100 of this embodiment eliminates the hassle that arises when combining the setting of the F / C combination ring 155 with the focus mode.

[0080] Furthermore, in this embodiment, the lens unit 150 is equipped with an F / C switch 153 and a three-value switch 156. When the F / C combination ring 155 is explicitly and uniquely set using these physical switches, the F / C setting set by these physical switches is used even when the focus mode is set to MF. When the F / C combination ring 155 is set as a control ring using these physical switches, the control ring is set without being set as a focus ring. When the operation of the F / C combination ring 155 is set using a physical switch in this way, the user is aware of whether the F / C combination ring 155 operates as a focus ring or a control ring. Therefore, by not automatically controlling the F / C combination ring 155 to operate as a focus ring, the user's awareness can be prioritized. On the other hand, if there is no F / C switch 153 or ternary switch 156, when the focus mode is MF, the F / C combined ring 155 is controlled to operate as a focus ring even if the control ring is set to F / C setting.

[0081] Note that the control is not limited to that described in this embodiment, and regardless of how the F / C combined ring 155 is set, when the focus mode is MF, the F / C combined ring may be set to operate in focus mode.

[0082] 6(a)-2, the present embodiment has been described with reference to the case where the focus mode can be set to be fixed to AF when the F / C combined ring 155 is operated as a control ring, but this is not the only case. For example, the focus mode may be fixed to AF when the F / C combined ring 155 is operated as a control ring without being set.

[0083] Furthermore, in this embodiment, the lens unit 150 is configured to be detachable from the camera 100, but the camera and the lens may be configured as an integrated unit. Furthermore, in this embodiment, the case where the combined operating member is the F / C combined ring 155 mounted on the lens unit 150 has been described, but it may also be an operating member mounted on the camera 100 side, for example. Furthermore, in this embodiment, the F / C switch 153 is mounted on the lens unit 150, but it may also be mounted on the camera 100 side, for example. The setting values ​​stored in the camera 100 may be stored in a control device that remotely controls the camera 100 via wired or wireless communication. Examples of devices that remotely control the camera 100 include a smartphone, a tablet PC, and a desktop PC.

[0084] <Second embodiment> In the second embodiment, differences from the first embodiment will be mainly described. In the second embodiment, a setting screen shown in Fig. 6(a)-3 is displayed instead of the setting screen shown in Fig. 6(a)-2 described in the first embodiment.

[0085] 6(a)-3 is an example of a detailed setting screen displayed on the camera 100 when the transition section 603 is selected. The detailed setting screen displays setting items 607 and 608. Check boxes are displayed for each of the setting items 607 and 608, and the user can select whether or not to set each of the setting items 607 and 608.

[0086] When the check box of the setting item 607 is selected, the focus mode is set to be fixed to AF when the F / C combined ring 155 is operated as a control ring. On the other hand, when the check box of the setting item 607 is deselected, the setting fixed to AF is canceled. When the check box of the setting item 608 is selected, the F / C combined ring 155 is set to be fixed as a focus ring when the focus mode is set to manual focus. On the other hand, when the check box of the setting item 608 is deselected, the setting to be fixed as a focus ring is canceled. Therefore, when the F / C combined ring 155 is operated as a control ring, it can be set to be fixed to AF, and when the focus mode is set to manual focus, it can be set to be fixed as a focus ring at the same time.

[0087] Note that in the initial display (default settings), setting item 607 is selected. Therefore, when the F / C combination ring 155 is operated as a control ring, the focus mode is normally fixed to AF. On the other hand, if the lens unit is equipped with the F / C combination ring 155 but not with a focus ring, focus adjustment is not possible when the F / C combination ring 155 is operated as a control ring. Since focus adjustment is not possible even when the focus mode is MF, the focus mode is basically fixed to AF when the F / C combination ring 155 is operated as a control ring. However, the user can intentionally cancel the fixation to AF by deselecting the check box of setting item 607.

[0088] Next, the operation of the F / C combined ring and the focus mode determination process in step S304 of FIG. 3 will be described in detail with reference to FIG. In step S1001, the system control unit 50 determines whether or not the F / C dual-purpose ring determination process flag was set in step S413 of Fig. 4. If the flag is set, the process proceeds to S1002. On the other hand, if the flag is not set, the process proceeds to S1004. In step S1002, the system control unit 50 determines whether or not a selection has been made to fix the F / C combination ring 155 as a focus ring during manual focus. Specifically, the system control unit 50 determines whether or not a checkbox for the setting item 608 for fixing as a focus ring has been selected on the setting screen in FIG. 6(a)-3. If a selection has been made to fix the F / C combination ring 155 as a focus ring, the process proceeds to step S1003. On the other hand, if a selection has not been made to fix the F / C combination ring 155 as a focus ring, the process proceeds to step S1004.

[0089] In step S1003, the system control unit 50 sets the F / C combined ring 155 to operate as a focus ring, and proceeds to step S1004. That is, the system control unit 50 controls the F / C combined ring 155 to operate as a focus ring regardless of the F / C setting.

[0090] In step S1004, the system control unit 50 determines whether or not the focus mode determination process flag was set in step S520 of Fig. 5. If the flag is set, the process proceeds to S1005. On the other hand, if the flag is not set, the process ends the flowchart of Fig. 10. In step S1005, the system control unit 50 determines whether or not a selection has been made to fix to AF when using the F / C combined ring 155 as a control ring. Specifically, the system control unit 50 determines whether or not a checkbox for the setting item 607 to fix to AF has been selected on the setting screen in FIG. 6(a)-3. If a selection has been made to fix to AF, the process proceeds to step S1006. On the other hand, if a selection has not been made to fix to AF, the flow chart in FIG. 10 ends. In step S1006, the system control unit 50 sets the focus mode to AF, and ends the flowchart of Fig. 10. That is, the system control unit 50 controls the focus mode to AF regardless of the focus mode setting in the AF / MF setting.

[0091] <Third embodiment> In the third embodiment, differences from the first and second embodiments will be mainly described. The lens unit 150 has a lens (center-focus macro lens) that is capable of macro photography, whereby the lens unit 150 is photographed up close to a subject. The system control unit 50 determines whether the lens unit 150 is a center-focus macro lens based on the lens identification information received from the attached lens unit 150. If the lens unit 150 is a center-focus macro lens, the system control unit 50 sets the F / C combination ring 155 to operate as a focus ring.

[0092] Specifically, the third embodiment can be realized by replacing step S902 in the flowchart of FIG. 9 with the following process. In step S902, the system controller 50 determines whether the attached lens unit 150 is a center-focus macro lens, the focus mode is set to AF, and the focal length is closer than the threshold. If all of these conditions are met, the system controller 50 proceeds to step S903. On the other hand, if any of the conditions are not met, the flow chart of FIG. 9 ends.

[0093] When the process transitions to step S903, the F / C combined ring 155 is set to operate as a focus ring, and therefore the F / C combined ring 155 is controlled to operate as a focus ring even if the control ring is set in the F / C setting.

[0094] Note that step S902 in the third embodiment is not limited to the above-described processing, and the system control unit 50 may determine only whether or not the attached lens unit 150 is a center-focus macro lens. Also, in step S902 in the third embodiment, the system control unit 50 may determine whether or not the attached lens unit 150 is a center-focus macro lens and the focal length is closer than a threshold value. Furthermore, step S903 in the third embodiment may be applied to step S1002 in the second embodiment.
