Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, regarding adjustment of setting values such as exposure, for example, an auto mode for performing automatic adjustment and a manual mode for a user to manually change may be prepared. In this case, for example, when the user is in a state of manually adjusting in the manual mode and is switched to the auto mode due to an incorrect operation, the state of the manual adjustment may be wasted. For example, such a situation occurs in a model that inherits the settings of the auto mode when it is in the manual mode. That is, after the user sets in the manual mode and then becomes the auto mode due to an incorrect operation, the settings are changed by automatic adjustment. And even when returning to the manual mode, since the setting state of the auto mode is inherited, the state set by the previous manual operation cannot be reproduced. Also, in the manual mode, the set value may be changed due to an incorrect operation. Therefore, in view of these problems, the present disclosure proposes a technique for improving usability while preventing incorrect operations in mode switching and manual operations.

Means for Solving the Problems

[0005] The imaging device according to the present technology includes a mode operator that switches between a manual mode in which a set value related to imaging is changed according to an operation and an auto mode in which the set value related to imaging is automatically adjusted, and in response to detecting an operation in a first mode of the mode operator, performs a process of switching between the manual mode and the auto mode, and in response to detecting an operation in a second mode of the mode operator in the manual mode, performs a process of switching between a non-locked state in which a set value change operation in the manual mode is enabled and a locked state in which the set value change operation in the manual mode is disabled. Perform mode switching and lock / unlock switching in the manual mode according to the operation mode of the mode operator.

[0006] In the imaging device according to the present technology described above, the mode operator is an operator that can be pressed, and the operation in the first mode may be a long-press operation that is a continuous press for a predetermined time or longer, and the operation in the second mode may be a short-press operation that is a press for less than the predetermined time. For example, as a key or a button-type operator, the user is made to operate by distinguishing between long press and short press.

[0007] In the imaging device according to the present technology described above, the set values are a plurality of set values related to exposure, and a plurality of individual corresponding operators corresponding to the plurality of set values are provided as the mode operator. The control unit executes switching between the auto mode and the manual mode for the corresponding set value in response to the operation of the first aspect of the individual corresponding operator, and executes switching between the unlocked state and the locked state for the corresponding set value in response to the operation of the second aspect of the individual corresponding operator. For each of the plurality of set values, provide a mode operator such as a key or a button so that individual mode switching and switching between the locked state and the unlocked state are possible.

[0008] In the imaging device according to the present technology described above, the set values are a plurality of set values related to exposure, and a set operator corresponding to the plurality of set values collectively is provided as the mode operator. The control unit executes a collective switching between the auto mode and the manual mode for the plurality of set values in response to the operation of the first aspect of the set operator, and executes a collective switching between the unlocked state and the locked state for the plurality of set values in response to the operation of the second aspect of the set operator. Provide a set operator corresponding to the plurality of set values collectively so that collective mode switching and lock / unlock switching are possible.

[0009] In the imaging apparatus according to the present technology described above, the set values are a plurality of set values related to exposure. As the mode operator, a plurality of individual corresponding operators each individually corresponding to the plurality of set values and a set operator corresponding to the plurality of set values collectively are provided. The control unit executes switching between the auto mode and the manual mode for the set value corresponding to the operation of the first mode of the individual corresponding operator, and executes switching between the unlocked state and the locked state for the set value corresponding to the operation of the second mode of the individual corresponding operator. In response to the operation of the first mode of the set operator when some or all of the plurality of set values are in the manual mode, switching is executed so that all of the plurality of set values become the auto mode. In response to the operation of the second mode of the set operator when all of the plurality of set values are in the manual mode, it is conceivable to execute a collective switching between the unlocked state and the locked state for the plurality of set values. Provide individual corresponding operators individually corresponding to a plurality of set values and a set operator corresponding collectively, so that each can be used appropriately.

[0010] In the imaging apparatus according to the present technology described above, it is conceivable that the control unit sets the manual mode in the initial state. Enable the user's dial operation etc. with the initial state being the manual mode.

[0011] In the imaging apparatus according to the present technology described above, it is conceivable that the set value when the control unit makes a transition from the auto mode to the manual mode is the value in the immediately preceding auto mode. That is, the transition to the manual mode is made in a state where the set value automatically adjusted in the auto mode is carried over.

[0012] In the imaging device according to the present technology described above, the setting values are a plurality of setting values related to exposure, and in the manual mode, there are a plurality of setting value change operators each assigned to correspond to a certain setting value, and it is conceivable that the control unit performs control to cause a guide display indicating the setting value change operator corresponding to each setting value to be executed. Corresponding to each setting value in the manual mode, setting value change operators such as dials are provided respectively. In this case, it is made to display which setting value change operator corresponds to which setting value.

[0013] In the imaging device according to the present technology described above, there is a setting value change operator for changing a setting value in the manual mode, and it is conceivable that the control unit performs control to cause a guide display indicating that the operation of the setting value change operator is invalid in the auto mode and the locked state. It is presented that the setting value change operator is effective for setting value change operations when in the non-locked state in the manual mode, and is invalid otherwise.

[0014] In the imaging device according to the present technology described above, it is conceivable that there are a plurality of custom operators whose operation functions can be set and changed, and the plurality of individual corresponding operators can be assigned to different ones of the custom operators. It is made possible to arbitrarily assign a plurality of individual corresponding operators to a plurality of custom operators respectively.

[0015] In the imaging device according to the present technology described above, it is conceivable that there are a plurality of custom operators whose operation functions can be set and changed, and the set operator can be assigned to any one of the plurality of custom operators. It is made possible to arbitrarily assign the set operator to any one of the plurality of custom operators.

[0016] In the imaging device according to the present technology described above, it is conceivable that the setting value is the F value. Also, the set value may be a shutter speed value. Also, the set value may be an ISO value. That is, this technology is applied to the mode switching operation and lock operation of the set value related to exposure.

[0017] The control method according to this technology is a control unit in an imaging device provided with a mode operator for switching between a manual mode for changing set values related to imaging according to an operation and an auto mode for automatically adjusting set values related to imaging, which performs a process of switching between the manual mode and the auto mode in response to detecting an operation in a first aspect of the mode operator, and performs a process of switching between a non-lock state that enables a set value change operation in the manual mode and a lock state that disables the set value change operation in the manual mode in response to detecting an operation in a second aspect of the mode operator in the manual mode. This enables mode switching and lock state switching with the mode operator, and also reduces misoperations according to the operation aspect. The program according to this technology is a program that causes an arithmetic processing unit as a control unit to execute such processing. Thereby, the imaging device of this technology is realized.

Mode for Carrying Out the Invention

[0019] Hereinafter, the embodiments will be described in the following order. <1. Configuration of the imaging device> <2. Mode transition> <3. Processing of the first embodiment> <4. Processing of the second embodiment> <5. Processing of the third embodiment> <6. Display example> <7. Summary and modification examples>

[0020] <1. Configuration of the imaging device> FIG. 1 shows a perspective view of the imaging device 1 of the embodiment from the front, FIG. 2 shows a plan view, and FIG. 3 shows a rear view. In this example, the imaging device 1 is a digital camera that can execute, for example, still image imaging or moving image imaging. In the present embodiment, the imaging device 1 may be a still camera that can only capture still images, a video camera mainly used for moving image imaging, or the like.

[0021] In the imaging device 1, a lens barrel 2 is disposed on the front side of the camera body 3. When configured as a so-called lens interchangeable camera, the lens barrel 2 is detachable from the camera body 3, and the lens can be exchanged. Also, the lens barrel 2 may be non-detachable from the camera body 3. For example, there are a configuration example in which the lens barrel 2 is fixed to the camera body 3, and a configuration example in which, as a retractable type, the lens barrel 2 transitions between a state where it is retracted and stored in front of the camera body 3 and a state where it can be used in a protruding state.

[0022] On the back side (user side) of the imaging device 1, a display panel 4 using a display device such as a liquid crystal display (LCD) or an organic EL (Electro-Luminescence) display is provided. Also, as a viewfinder 5, a display unit formed using an LCD, an organic EL display, or the like is provided. The viewfinder 5 is not limited to an electronic viewfinder (EVF), and an optical viewfinder (OVF) may also be used.

[0023] The user can view an image and various types of information through the display panel 4 and the viewfinder 5. In this example, both the display panel 4 and the viewfinder 5 are provided in the imaging device 1, but the present invention is not limited to this. A configuration in which only one of the display panel 4 and the viewfinder 5 is provided, or a configuration in which both or either one of the display panel 4 and the viewfinder 5 is detachable may also be used.

[0024] Various operating elements are provided in the imaging device 1. For example, as the operating elements, various forms such as keys (buttons), dials, wheels, and combined pressing / rotating operating elements are arranged to realize various operating functions. In the figure, reference numerals are attached to show a shutter button 70 for a release operation, a mode dial 71 for selecting a shooting mode, and, as operating elements used in the description of the present embodiment, a front dial 72, a rear dial 73, a wheel 74, and custom keys C1, C2, C3, C4.

[0025] In this embodiment, regarding the set values related to exposure in particular, the switching between the auto mode and the manual mode, the change of the set values, and the switching between the locked state (non-operable state) and the unlocked state (operable state) of the set value change operation will be described. The operators related to this are the front dial 72, the rear dial 73, the wheel 74, and the custom keys C1, C2, C3, C4. Also, as set values related to exposure, there are the F value which is the set value of the aperture mechanism, the SS value which is the value of the shutter speed (hereinafter also referred to as "SS"), and the ISO value which is the gain value for the imaging signal.

[0026] As shown in FIG. 2, the custom keys C1, C2 are arranged on the upper surface of the camera body 3. As shown in FIG. 3, the custom keys C3, C4 are arranged on the back surface of the camera body 3. These custom keys C1, C2, C3, C4 are operators also called assignable buttons. In the initial state, a predetermined operation function is assigned, and the user can assign an arbitrary operation function. For example, in the initial state, the custom key C1 is the F value mode key 81, the custom key C2 is the ISO mode key 82, and the custom key C4 is the SS mode key 84. Also, the custom key C3 arranged on the left side of the back surface is, for example, the set key 83.

[0027] The F value mode key 81 is an operator for performing mode switching between the auto mode and the manual mode regarding the F value, and switching between the locked state and the unlocked state. The ISO mode key 82 is an operator for performing mode switching between the auto mode and the manual mode regarding the ISO value, and switching between the locked state and the unlocked state. The SS mode key 84 is an operator for performing mode switching between the auto mode and the manual mode regarding the SS value, and switching between the locked state and the unlocked state.

[0028] These F-value mode keys 81, ISO mode keys 82, and SS mode keys 84 are mode keys that individually correspond to the F-value, ISO value, and SS value, respectively. For the sake of explanation, these are collectively referred to as "individual correspondence keys".

[0029] In the figure, the F-value mode key 81, ISO mode key 82, and SS mode key 84 are shown as being assigned to the custom keys C1, C2, and C4, but this assignment can be arbitrarily changed by the user. Also, the assumption that the F-value mode key 81, ISO mode key 82, and SS mode key 84 are assigned to any of the custom keys is just an example, and three dedicated mode operators for these functions may be provided.

[0030] The set key 83 is an operator for collectively performing mode switching and switching between the locked state and the unlocked state for the F-value, ISO value, and SS value. In the figure, the set key 83 is shown as being assigned to the custom key C3, but this assignment can be arbitrarily changed by the user. Also, the assumption that the set key 83 is assigned to any of the custom keys is just an example, and a dedicated mode operator for the set key may be provided.

[0031] Also, an example of providing both the three individual correspondence keys (81, 82, 84) and the set key 83 is given. However, for the processing of the first embodiment described later, at least the individual correspondence keys need to be provided. Also, for the processing of the second embodiment, at least the set key 83 needs to be provided. That is, the individual correspondence keys (81, 82, 84) and the set key 83 do not necessarily have to be provided both.

[0032] In the present disclosure, the set key 83 and the individual correspondence keys (F-value mode key 81, ISO mode key 82, SS mode key 84) are collectively referred to as "mode operators". That is, the mode operator refers to an operator for switching between the auto mode and the manual mode.

[0033] The front dial 72, the rear dial 73, and the wheel 74 are each used as an operator for changing the set values of, for example, the SS value, the ISO value, and the F value. That is, they are operators for changing the set values in the manual mode. For example, when the SS value is in the manual mode and unlocked, the user operates the front dial 72 to change the SS value. Also, for example, when the ISO value is in the manual mode and unlocked, the user operates the rear dial 73 to change the ISO value. Also, for example, when the F value is in the manual mode and unlocked, the user operates the wheel 74 to change the F value.

[0034] The assignment of these set values to the front dial 72, the rear dial 73, and the wheel 74 may be fixed or may be arbitrarily changed by the user. For example, the user can assign the front dial 72 as an operator for changing the set values of the ISO value or the F value to suit the user's personal convenience.

[0035] Next, an example of the internal configuration of the imaging device 1 will be described with reference to FIG. 4. In FIG. 4, an example is shown in which the imaging device 1 is configured by being divided into a camera body 3 and a lens barrel 2.

[0036] The imaging device 1 includes an image sensor 12, a camera signal processing unit 13, a recording control unit 14, a display unit 15, an output unit 16, an operation unit 17, a power supply unit 18, a camera control unit 30, and a memory unit 31 in the camera body 3. The lens barrel 2 includes a lens system 21, a lens system drive unit 22, and a lens barrel control unit 23.

[0037] The lens system 21 in the lens barrel 2 includes lenses such as a zoom lens and a focus lens, and a diaphragm mechanism. The light (incident light) from the subject is guided by this lens system 21 and focused on the image sensor 12.

[0038] The imaging device 12 is configured as, for example, a CCD (Charge Coupled Device) type, a CMOS (Complementary Metal Oxide Semiconductor) type, or the like. In this imaging device 12, for the electrical signal obtained by photoelectrically converting the received light, for example, CDS (Correlated Double Sampling) processing, AGC (Automatic Gain Control) processing, etc. are executed, and further A / D (Analog / Digital) conversion processing is performed. Then, the imaging signal as digital data is output to the subsequent camera signal processing unit 13 and camera control unit 30.

[0039] The camera signal processing unit 13 is configured as an image processing processor by, for example, a DSP (Digital Signal Processor) or the like. This camera signal processing unit 13 performs various signal processes on the digital signal (imaging image signal) from the imaging device 12. For example, as a camera process, the camera signal processing unit 13 performs pre-processing, synchronization processing, YC generation processing, resolution conversion processing, codec processing, etc.

[0040] In the pre-processing, for the imaging image signal from the imaging device 12, clamp processing for clamping the black levels of R (red), G (green), and B (blue) to a predetermined level, correction processing between the color channels of R, G, and B, etc. are performed. In the synchronization processing, color separation processing is performed so that the image data for each pixel has all the color components of R, G, and B. For example, in the case of an imaging device using a Bayer array color filter, demosaicing processing is performed as the color separation processing. In the YC generation processing, a luminance (Y) signal and a color (C) signal are generated (separated) from the R, G, and B image data. In the resolution conversion processing, resolution conversion processing is executed on the image data subjected to various signal processes.

[0041] The recording control unit 14 performs recording and playback on a recording medium such as a non-volatile memory. For example, the recording control unit 14 performs a process of recording an image file such as moving image data or still image data, or a thumbnail image on the recording medium. The actual form of the recording control unit 14 can be considered in various ways. For example, the recording control unit 14 may be configured as a flash memory built into the imaging device 1 and its write / read circuit, or may be in the form of a card recording / playback unit that performs recording / playback access on a recording medium detachable from the imaging device 1, such as a memory card (a portable flash memory, etc.). Also, in the form built into the imaging device 1, it may be realized as an HDD (Hard Disk Drive) or the like.

[0042] The display unit 15 is a display unit that performs various displays for the imaging person, and specifically shows the display panel 4 and the viewfinder 5 shown in FIG. 3. The display unit 15 executes various displays on the display screen based on the instructions of the camera control unit 30. For example, the display unit 15 displays a playback image of the image data read from the recording medium by the recording control unit 14. Also, the image data of the captured image resolution-converted for display by the camera signal processing unit 13 is supplied to the display unit 15. The display unit 15 performs a display based on the image data of the captured image in response to the instructions of the camera control unit 30, thereby displaying a so-called through image (a captured monitor image based on the subject light received by the imaging element 12). Also, the display unit 15 executes displays such as various operation menus, icons, messages, etc., that is, displays as a GUI (Graphical User Interface) on the screen based on the instructions of the camera control unit 30.

[0043] The output unit 16 performs wired or wireless data communication and network communication with external devices. For example, it transmits and outputs captured image data (still image files or moving image files) to an external display device, recording device, playback device, information processing device, etc. Also, assuming that the output unit 16 is a network communication unit, for example, it may communicate via various networks such as the Internet, home network, LAN (Local Area Network), etc., and perform various data transmissions and receptions with servers, terminals, etc. on the network.

[0044] The operation unit 17 generally shows an input device for the user to perform various operation inputs. Specifically, the operation unit 17 shows various operation elements provided on the camera body 3. That is, the operation unit 17 includes the above-described F-value mode key 81, ISO mode key 82, SS mode key 84, set key 83, front dial 72, rear dial 73, wheel 74, etc. An operation of the user is detected by the operation unit 17, and a signal corresponding to the input operation is sent to the camera control unit 30. As this operation unit 17, not only operation elements such as physical keys and dials may be used, but also a touch panel may be used. For example, a touch panel may be formed on the display panel 4, and various operations may be enabled by touch panel operations using icons, menus, etc. displayed on the display panel 4. Alternatively, the operation unit 17 may be in a form that detects a tap operation, etc. of the user by a touch pad or the like. Furthermore, the operation unit 17 may be configured as a reception unit for operation signals from an external operation device such as a separate remote controller.

[0045] The power supply unit 18 generates, for example, a necessary power supply voltage Vcc for each unit from a battery loaded inside, and supplies it as an operating voltage. In a state where the lens barrel 2 is attached to the imaging device 1, the power supply voltage Vcc by the power supply unit 18 is configured to be supplied also to the circuits and motors inside the lens barrel 2. Note that the power supply unit 18 may be formed with a circuit for charging the battery and a circuit for generating the power supply voltage Vcc using, as a power supply, a DC voltage converted and input by an AC adapter connected to a commercial AC power supply.

[0046] The camera control unit 30 is composed of a microcomputer (arithmetic processing unit) equipped with a CPU (Central Processing Unit). The memory unit 31 stores information and the like used by the camera control unit 30 for processing. As the illustrated memory unit 31, for example, ROM (Read Only Memory), RAM (Random Access Memory), flash memory, etc. are comprehensively shown. The memory unit 31 may be a memory area built into the microcomputer chip as the camera control unit 30, or may be composed of a separate memory chip. By executing the programs stored in the ROM, flash memory, etc. of the memory unit 31, the camera control unit 30 controls the entire imaging device 1 and the lens barrel 2. For example, the camera control unit 30 controls the operations of the necessary parts regarding the shutter speed and ISO value control of the imaging element 12, instructions for various signal processes in the camera signal processing unit 13, imaging operations and recording operations according to the user's operations, playback operations of the recorded image files, user interface operations, etc. Regarding the lens system 21, the camera control unit 30 performs, for example, autofocus control to automatically focus on the target subject, instructions for the aperture mechanism for F value control, etc.

[0047] The RAM in the memory unit 31 is used for temporarily storing data, programs, etc. as a work area during various data processes of the CPU of the camera control unit 30. The ROM and flash memory (non-volatile memory) in the memory unit 31 are used for storing the OS (Operating System) for the CPU to control each part, content files such as image files, application programs for various operations, firmware, etc.

[0048] When the lens barrel 2 is attached to the camera body 3, the camera control unit 30 communicates with the lens barrel control unit 23 and gives various instructions. In the lens barrel 2, for example, a lens barrel control unit 23 by a microcomputer is mounted, and various data communications are possible with the camera control unit 30. In the case of this embodiment, the camera control unit 30 gives drive instructions regarding the zoom lens, focus lens, aperture mechanism, etc. to the lens barrel control unit 23. The lens barrel control unit 23 controls the lens system drive unit 22 according to these drive instructions, and executes the operation of the lens system 21. Note that in a state where the lens barrel 2 is attached to the camera body 3, it is configured such that wired communication is executed between the camera control unit 30 and the lens barrel control unit 23. However, it may be configured such that the camera control unit 30 and the lens barrel control unit 23 can perform wireless communication.

[0049] The lens system drive unit 22 is provided with, for example, a motor driver for the zoom lens drive motor, a motor driver for the focus lens drive motor, a motor driver for the motor of the aperture mechanism, etc. These motor drivers apply a drive current to the corresponding driver according to an instruction from the lens barrel control unit 23, and execute the movement of the focus lens and zoom lens, the opening and closing of the aperture blades of the aperture mechanism, etc.

[0050] <2. Mode Transition> For example, in the imaging device 1 configured as described above, hereinafter, the mode transition regarding exposure will be described focusing on it.

[0051] As described above, the set values regarding exposure are the F value, SS value, and ISO value. As control modes for these, an auto mode and a manual mode are prepared. The auto mode is a mode in which, for example, the camera control unit 30 automatically optimizes the set value. The manual mode is a mode in which, for example, the user manually adjusts the set value using the above-described front dial 72, rear dial 73, wheel 74, etc.

[0052] In the case of this embodiment, for each of the F value, the SS value, and the ISO value, the auto mode and the manual mode can be individually selected, and the exposure can be set according to the combination thereof. Also, when switching from the auto mode to the manual mode, it is assumed that the manual mode starts from the value inherited from the value of the auto mode immediately before the switch. As a result, the user can roughly adjust in the auto mode and then manually adjust in the manual mode to achieve the desired state, which is extremely convenient to use.

[0053] However, if the mode is switched from the manual mode to the auto mode by an unintended operation of the user, the setting value set manually last time cannot be restored even when switching back to the manual mode. This is because when the auto mode is entered, the setting value is automatically adjusted, and when switching back to the manual mode, the setting value is inherited. Especially when the operator for mode switching is located at an easily accessible position, there is a high risk of accidental operation. Therefore, in this embodiment, first, the switching operation between the auto mode and the manual mode is performed by the first mode of operation of the mode operator (individual corresponding keys (81, 82, 84) or the set key 83).

[0054] It is assumed that this first mode of operation is less likely to cause accidental operation compared to the second mode of operation described below. For example, the user feels that the second mode of operation is a simpler operation, or an easier operation, or has better operation responsiveness than the first mode of operation. Specifically, the first mode of operation is a long press, and the second mode of operation is a short press. A short press is a pressing operation for a predetermined time less than, for example, less than 1 second. A long press is a continuous pressing operation for a predetermined time more than, for example, 1 second.

[0055] Also, in the manual mode, the user can arbitrarily change the setting values using setting value change operators such as the front dial 72, the rear dial 73, and the wheel 74. However, there is a possibility that the user may accidentally touch these setting value change operators and the setting values may be changed. Also, the user may not notice that the settings have been changed, and unintended imaging may occur.

[0056] Therefore, in the present embodiment, it is possible to select a locked state in the manual mode. The locked state is a state in which the setting values are not changed even if the setting value change operators are operated. That is, the normal manual mode in which the setting values are changed by operating the setting value change operators is assumed to be an unlocked state, and it is possible to select between the unlocked state and the locked state within the manual mode. However, providing a separate operator for switching between the locked state and the unlocked state is disadvantageous in terms of the design of the key arrangement etc. of the camera body 3, and the operability deteriorates due to too many keys, and the switching operation between the locked state and the unlocked state becomes troublesome. Therefore, in the present embodiment, the mode operator is made to be also usable for switching between the locked state and the unlocked state. That is, the switching between the locked state and the unlocked state is performed by the second mode of operation of the mode operator (the individual corresponding keys (81, 82, 84) and the set key 83).

[0057] By providing the first mode of operation and the second mode of operation for the mode operator in this way, it is possible to prevent the setting values related to the exposure from being unintentionally changed due to an accidental operation. That is, by making the switching between the auto mode and the manual mode of the F value, the SS value, and the ISO value be performed by the first mode of operation (for example, a long press) of the mode operator, it is possible to make it difficult for an unintended mode switch to occur. If it is a long press, even if the mode operator is accidentally pressed, that is usually equivalent to a short press, so the mode switch does not occur. Also, by making it possible to switch between the locked state and the unlocked state by operating the mode operator in the second mode, the locked state in the manual mode can be set using the mode operator as it is. As a result, it is possible to expect an effect of preventing an incorrect operation in which the user accidentally touches a setting value change operator such as the front dial 72 in the manual mode and the setting value is changed without the user's knowledge.

[0058] Figure 5 shows a state transition according to the operation of the mode operator and the like. For example, when in the auto mode, it transitions to the manual mode by operating u1 (long press). When in the manual mode, it transitions to the auto mode by operating u2 (long press).

[0059] In the manual mode, it is in the unlocked state at the beginning of the transition, but transitions to the locked state (manual locked state) by operating u4 (short press). When in the locked state, it returns to the unlocked state by operating u5 (short press). Also, when operating u6 (long press) is performed while in the locked state, it transitions to the auto mode.

[0060] When in the unlocked state in the manual mode, the operation u3 (setting value change operation) by the front dial 72, the rear dial 73, and the wheel 74, which are setting value change operators, becomes effective. When in the locked state in the manual mode, operations by the front dial 72, the rear dial 73, and the wheel 74, which are setting value change operators, are not accepted as invalid. That is, the setting value cannot be changed.

[0061] <3. Processing of the First Embodiment> A processing example regarding mode switching of the camera control unit 30 as the first embodiment will be described with reference to FIG. 6. This first embodiment assumes a case where an F-value mode key 81, an ISO mode key 82, and an SS mode key 84 are provided as individual corresponding keys as mode operators. The individual corresponding keys shown in FIG. 6 refer to any one of the F-value mode key 81, the ISO mode key 82, and the SS mode key 84. When considering the description of FIG. 6 as an explanation regarding the F-value mode, the individual corresponding key is the F-value mode key 81. Also, when the wheel 74 is assigned to the operation of changing the F-value, the setting value change operator is the wheel 74. Also, when considering the description of FIG. 6 as an explanation regarding the SS-value mode, the individual corresponding key is the SS mode key 84. Also, when the front dial 72 is assigned to the operation of changing the SS value, the setting value change operator is the front dial 72. The same concept applies to the ISO value. Note that "ct5", "ct6", "ct7", and "ct8" in FIG. 6 are used in the description of the third embodiment. Also, FIG. 6 only shows the processing for the state transition shown in FIG. 5, and does not touch on the processing related to actual exposure control such as the automatic change of the setting value in the auto mode and the instructions corresponding thereto (the same applies to FIGS. 7, 8, and 9 described later).

[0062] For example, it is assumed that the camera control unit 30 selects the manual mode in the initial state when the power is turned on. Then, after (or when it becomes possible) an operation related to mode switching or setting value change as an exposure setting is started until the setting change is completed, the camera control unit 30 proceeds from step S101 to step S102 in FIG. 6. For example, when the imaging device 1 transitions to a playback mode or the like where operations related to exposure settings cannot be performed, or when a certain period of time has elapsed after the last operation related to exposure, it is determined that the setting change is completed.

[0063] In step S102, the camera control unit 30 maintains the unlocked state of the manual mode. In the unlocked state of this manual mode, the camera control unit 30 monitors the long-press operation of the individual corresponding key (any one of the F-value mode key 81, ISO mode key 82, and SS mode key 84) in step S103, monitors the short-press operation of the individual corresponding key in step S104, and monitors the operation of the setting value change operator (any one of the front dial 72, rear dial 73, and wheel 74) in step S105.

[0064] When the operation of the setting value change operator is detected in step S105, the camera control unit 30 proceeds to step S140 and changes the setting value (any one of the F-value, SS value, and ISO value) according to the operation.

[0065] When the long-press operation of the individual corresponding key is detected in step S103, the camera control unit 30 proceeds to step S120 and switches to the auto mode. When in the auto mode, the camera control unit 30 monitors the long-press operation of the individual corresponding key in step S121 while maintaining the auto mode in step S120 until it is determined in step S122 that the setting change has ended.

[0066] When the long-press operation of the individual corresponding key is detected in step S121, the camera control unit 30 proceeds to step S130 so that the initial value of the setting value in the manual mode inherits the setting value of the auto mode at that time. Then it transitions to the manual mode in step S102. For example, assuming that the long-press of the F-value mode key 81 is detected, in step S130, the F-value set in the auto mode process immediately before this operation is maintained, and it transitions to the manual mode in step S102. Therefore, in that manual mode, the user can perform a change operation to increase or decrease the F-value starting from the F-value in the previous auto mode.

[0067] When the camera control unit 30 detects a short press operation of the individual response key in step S104 in the manual mode, it proceeds to step S110 and switches to the locked state of the manual mode. For example, when a short press of the F-value mode key 81 is detected, the F-value is set to a locked state where it cannot be changed. In the locked state, until it is determined in step S111 that the setting change has ended, the camera control unit 30 monitors the long press operation of the individual response key in step S112 while maintaining the locked state in step S110, and also monitors the short press operation of the individual response key in step S113.

[0068] If the camera control unit 30 detects a long press operation of the individual response key in step S112, it proceeds to step S120 and switches to the auto mode for the setting value corresponding to that individual response key. If the camera control unit 30 detects a short press operation of the individual response key in step S113, it proceeds to step S102, releases the locked state for the setting value corresponding to that individual response key, and enables the change of the setting value by the setting value change operator.

[0069] By applying the above processing of FIG. 6 to each of the F-value mode key 81, ISO mode key 82, and SS mode key 84, the camera control unit 30 can switch between the auto mode and the manual mode for the F-value, ISO value, and SS value respectively, and also switch between the locked state and the unlocked state, thereby reducing the possibility of the setting value being changed due to an accidental operation.

[0070] <4. Processing of the Second Embodiment> An example of the processing of the second embodiment will be described with reference to FIG. 7. This is an example in which the F-value, ISO value, and SS value are collectively switched in mode by the set key 83. Note that "ct1", "ct2", "ct3", and "ct4" in FIG. 7 are used in the description of the third embodiment.

[0071] For example, assume that the initial state when the camera is powered on selects the manual mode. And during the period until it is determined that the setting change for exposure is completed, the camera control unit 30 proceeds from step S201 to step S202 in FIG. 7. In step S202, the camera control unit 30 maintains the unlocked state of the manual mode for all of the F value, ISO value, and SS value.

[0072] In this unlocked state of the manual mode, the camera control unit 30 monitors the long press operation of the set key 83 in step S203, monitors the short press operation of the set key 83 in step S204, and monitors the operation of the setting value change operator (all of the front dial 72, rear dial 73, and wheel 74) in step S205.

[0073] When the operation of the setting value change operator is detected in step S205, the camera control unit 30 proceeds to step S240 and changes the setting value (any one of the F value, SS value, and ISO value) according to the operation. For example, if the wheel 74 is operated, the F value is changed. If the front dial 72 is operated, the SS value is changed. If the rear dial 73 is operated, the ISO value is changed.

[0074] When the long press operation of the set key 83 is detected in step S203, the camera control unit 30 proceeds to step S220 and switches all of the F value, ISO value, and SS value to the auto mode. When in the auto mode, the camera control unit 30 monitors the long press operation of the set key 83 in step S221 while maintaining the auto mode in step S220 during the period until it is determined that the setting change is completed in step S222.

[0075] When the long press operation of the set key 83 is detected in step S221, the camera control unit 30 proceeds to step S230 so that the initial values of the setting values in the manual mode inherit the respective setting values (F value, SS value, ISO value) of the auto mode at that time. And it transitions to the manual mode in step S202.

[0076] When the camera control unit 30 detects a short press operation of the set key 83 in step S204 in the manual mode, it proceeds to step S210 and switches all of the F value, ISO value, and SS value to the locked state in the manual mode. In the locked state, until it is determined in step S211 that the setting change is completed, the camera control unit 30 monitors the long press operation of the set key 83 in step S212 while maintaining the locked state of the F value, ISO value, and SS value in step S210, and also monitors the short press operation of the set key 83 in step S213.

[0077] When the camera control unit 30 detects a long press operation of the set key 83 in step S212, it proceeds to step S220 and switches all of the F value, ISO value, and SS value to the auto mode. When the camera control unit 30 detects a short press operation of the set key 83 in step S213, it proceeds to step S202, releases the locked state for all of the F value, ISO value, and SS value, and enables the change of the set value by the set value change operator.

[0078] By the camera control unit 30 performing the processing of FIG. 7 above, it becomes possible to collectively switch the mode and switch between the locked state and the unlocked state for the F value, ISO value, and SS value. As a result, it can be expected to improve the operability of the user.

[0079] <5. Processing of the Third Embodiment> As a third embodiment, an example in the case of using both the individual response key and the set key 83 will be described. FIG. 8 shows an example of the processing from the state after the operation of the individual response key. That is, the individual auto / manual setting in step S100 shows the whole of FIG. 6.

[0080] In the state where the processing according to the operation of the individual response key is being performed in the processing of FIG. 6 described above, the camera control unit 30 monitors steps S301 and S302 in FIG. 8. In step S301, the camera control unit 30 monitors whether the set key 83 has been short-pressed. In step S302, the camera control unit 30 monitors whether the set key 83 has been long-pressed.

[0081] When the camera control unit 30 detects a short press of the set key 83 in step S301, in step S303, it determines whether all of the F-value, ISO value, and SS value are in an unlocked state in the manual mode at that time. If all are in an unlocked state in the manual mode, as shown by "ct1" in the auto / manual setting of the set in step S200, it proceeds to step S210 in FIG. 7 and locks all of the F-value, ISO value, and SS value. Note that step S200 indicates the entire process in FIG. 8.

[0082] In step S303, if the condition that all of the F-value, ISO value, and SS value are in an unlocked state in the manual mode is not met, the camera control unit 30 determines in step S304 whether all of the F-value, ISO value, and SS value are in a locked state in the manual mode. If this is the case, as shown by "ct2", it proceeds to step S202 in FIG. 7 and unlocks all of the F-value, ISO value, and SS value.

[0083] That is, when all of the F-value, ISO value, and SS value are in a locked state, a short press of the set key 83 can return all to an unlocked state. Also, when all of the F-value, ISO value, and SS value are in an unlocked state, a short press of the set key 83 can lock all of them. When the conditions in steps S303 and S304 in FIG. 8 are not met, a short press of the set key 83 is invalidated and it returns to step S100.

[0084] When the long - press operation of the set key 83 is detected in step S302, the camera control unit 30 determines in step S305 whether any of the F - value, ISO - value, and SS - value is in the manual mode (unlocked state or locked state) at that time. If any of them is in the manual mode, it proceeds to step S220 in FIG. 7 as shown by "ct3", and locks all of the F - value, ISO - value, and SS - value.

[0085] In step S305, when any of the F - value, ISO - value, and SS - value does not meet the condition of being in the manual mode, that is, when all are in the auto mode, the camera control unit 30 proceeds to step S230 in FIG. 7 as shown by "ct4", and transitions to the manual mode while inheriting the F - value, ISO - value, and SS - value at that time.

[0086] That is, when even one of the F - value, ISO - value, and SS - value is in the manual mode, all can be set to the auto mode by long - pressing the set key 83. Also, when all of the F - value, ISO - value, and SS - value are in the auto mode, all can be set to the manual mode by long - pressing the set key 83.

[0087] FIG. 9 shows an example of the process from the state after the operation of the set key 83. That is, it is the process starting from the case where the auto / manual setting process of the set in step S200 is performed. The camera control unit 30 monitors steps S351 and S352 in FIG. 9. In step S351, the camera control unit 30 monitors whether the individual response key has been short - pressed. In step S352, the camera control unit 30 monitors whether the individual response key has been long - pressed.

[0088] When the short - press operation of the individual response key is detected in step S351, the camera control unit 30 determines in step S354 whether the current F - value, ISO - value, and SS - value are all in the locked state in the manual mode. If all are in the locked state in manual mode, as shown by "ct7" in step S100, the process proceeds to step S102 in FIG. 6, and the set value (any one of the F value, ISO value, and SS value) corresponding to the operated individual corresponding key is set to the unlocked state.

[0089] In step S354, if all of the F value, ISO value, and SS value are in the unlocked state in manual mode, the camera control unit 30 proceeds to step S110 in FIG. 6 as shown by "ct8" in step 100, and sets the set value (any one of the F value, ISO value, and SS value) corresponding to the operated individual corresponding key to the locked state.

[0090] After all of the F value, ISO value, and SS value are set to the locked state or the unlocked state by the set key 83, by briefly pressing the individual corresponding key, the set value corresponding to the individual corresponding key can be returned to the unlocked state or set to the locked state.

[0091] When a long press operation of the individual corresponding key is detected in step S352, the camera control unit 30 determines in step S353 whether the F value, ISO value, and SS value are all in the auto mode at present. If all are in the auto mode, the process proceeds to step S130 in FIG. 6 as shown by "ct5" in step S100, and the set value (any one of the F value, ISO value, and SS value) corresponding to the operated individual corresponding key is set to the manual mode while inheriting the value in the auto mode.

[0092] In step S353, if it is determined that not all of the F value, ISO value, and SS value are in the auto mode, that is, all are in the manual mode, the camera control unit 30 proceeds to step S120 in FIG. 6 as shown by "ct6" in step 100, and sets the set value (any one of the F value, ISO value, and SS value) corresponding to the operated individual corresponding key to the auto mode.

[0093] That is, after all of the F value, ISO value, and SS value are set to the manual mode or all to the auto mode by the set key 83, by performing a long-press operation on the individual response key, it is possible to switch the mode with respect to the set value corresponding to the individual response key.

[0094] <6. Display example> The display examples corresponding to the switching between the auto mode and the manual mode and the switching between the locked state and the unlocked state as described above will be described. FIG. 10 shows an example of the display of various icons on the display panel 4, for example. The camera control unit 30 causes the SS value display 50, F value display 51, ISO value display 52, and dial guides 53, 54, 55 to be displayed on the display panel 4 as setting values related to exposure and numerical values and icons related to the mode. These may be displayed on the viewfinder 5.

[0095] The SS value display 50 indicates the current SS value, for example, as "1 / 250". The F value display 51 indicates the current F value, for example, as "F5.6". The ISO value display 52 indicates the current ISO value. In the figure, it is shown that the ISO sensitivity is auto as "ISO AUTO", but the numerical value may be shown as "ISO 200" in some cases.

[0096] The dial guides 53, 54, 55 indicate which setting value is assigned to which dial (or wheel). The dial guide 53 indicates the front dial 72, and in the figure, it is shown that the front dial 72 is assigned to the operation of the F value by overlapping the character "Av". The dial guide 54 indicates the rear dial 73, and in the figure, it is shown that the rear dial 73 is assigned to the operation of the ISO value by overlapping the character "ISO". The dial guide 55 shows the wheel 74, and in the figure, the characters "Tv" are superimposed, indicating that the wheel 74 is assigned to the operation of the SS value.

[0097] Through such numerical displays and icons, various states are presented to the user. FIG. 11 shows an example of a display that changes according to mode transitions and lock states, taking the SS value as an example. Note that in FIG. 11, different from the example in FIG. 10, it is shown in a state where the operation of the SS value is assigned to the rear dial 73. That is, the dial guide 54 becomes the display of the SS value setting value change operator. The operations u1, u2, u3, u4, u5 in FIG. 11 have the same meaning as in FIG. 5.

[0098] In the auto mode, an auto mark 57 including the character "A" is added to the SS value display 50, indicating that it is in the auto mode. The character "Tv" is added to the dial guide 54 indicating the rear dial 73, showing that the rear dial 73 is an operator for the SS value. However, in the case of the auto mode, it is shown by the prohibition mark 56 that the operation of the rear dial 73 is invalid.

[0099] When transitioning to the manual mode (unlocked state), the auto mark 57 is erased, indicating that it is in the manual mode. In the dial guide 54, the prohibition mark 56 is erased, showing that the rear dial 73 can be used for the operation of the SS value. When the SS value is changed by the operation of the rear dial 73 (operation u3), it may be explicitly indicated that the operation is in progress, such as by changing the display color of the SS value display 50.

[0100] When transitioning to the manual mode (locked state), the prohibition mark 56 is displayed in the dial guide, indicating that the operation of the rear dial 73 is invalidated.

[0101] Figure 12 organizes and shows the set values (SS value display 50) and the changes in the display of the dial guide 54 in each of the above states. The presence or absence of the auto mark 57 indicates the difference between the auto mode and the manual mode. Regarding the dial guide 54, it is shown that the operation is prohibited by the prohibition mark 56 during the auto mode and when the manual mode is locked.

[0102] Although the above has been shown for the SS value display 50, the same applies to the F value display 51 and the ISO value display 52, where the auto mark 57 is added in the auto mode. Regarding the dial guides 53 and 55 as well, it is shown that the operation is prohibited by the prohibition mark 56 during the auto mode and when the manual mode is locked.

[0103] Note that the above display examples are just examples. Various display examples of characters, icons, etc. indicating the auto mode and the manual mode are conceivable. Regarding the dial guides 53, 54, and 55, the display examples of the assignment and the display indicating the inoperable state are not limited to the prohibition mark 56, and other examples are also conceivable. Also, in the locked state, instead of the prohibition mark 56, an icon or character indicating the locked state may be displayed.

[0104] <7. Summary and Variation Examples> According to the above embodiments, the following effects can be obtained. The imaging device 1 according to the embodiment includes mode operators (81, 82, 83, 84) that switch between a manual mode for changing imaging-related setting values according to operations and an auto mode for automatically adjusting imaging-related setting values. Further, in response to detecting an operation of the first aspect of the mode operator (for example, a long press), a process of switching between the manual mode and the auto mode is performed, and in response to detecting an operation of the second aspect of the mode operator (for example, a short press) in the manual mode, a camera control unit 30 that performs a process of switching between an unlock state that enables a setting value change operation and a lock state that disables the setting value change operation is provided. If the mode operators (81, 82, 83, 84) are configured to switch between the auto mode and the manual mode by a simple pressing operation or the like, the mode may be switched even when the user touches it unintentionally. On the other hand, by having the camera control unit 30 determine a plurality of operation aspects for the mode operator and perform mode switching when a specific operation of the first aspect is detected, it is possible to prevent mode switching from occurring due to an unintended operation by the user. This prevents the setting value from being changed unintentionally and improves usability. Also, by setting the lock state in the manual mode, it is possible to prevent the setting values from being changed due to accidental contact with the front dial 72, the rear dial 73, or the wheel 74. Furthermore, by enabling these mode switches and lock state / unlock state switches with a single mode operator, the number of operators is not increased unnecessarily.

[0105] In the embodiment, an example is given in which the mode operator is an operator that can be pressed, the operation of the first aspect is a long press operation that is a continuous press for a predetermined time or more, and the operation of the second aspect is a short press operation that is a press for less than the predetermined time. Mode switching is performed by long-pressing the mode operators (81, 82, 83, 84). It is assumed that long-pressing is a more conscious operation compared to short-pressing. Also, if it is touched unconsciously, it will not be a long-press. Therefore, by using long-pressing as the operation for mode switching, it is effective in preventing unintended mode switching. Regarding short-pressing, although an unintended operation may occur, since it remains in the manual mode, no unintended setting value change will occur. And by distinguishing between long-pressing and short-pressing, mode switching and lock / unlock switching in the manual mode can be realized with simple key or button-type operators.

[0106] Note that examples other than long-pressing and short-pressing can also be considered for the operations of the first mode and the second mode. It is desirable that the operation of the first mode is less likely to cause an incorrect operation than the operation of the second mode. As described above, the operation of the second mode is considered to be a simpler operation, or an easier operation, or an operation with better operation responsiveness than the operation of the first mode for the user. For example, there are the following examples. · The operation of the second mode is a single press, and the operation of the first mode is a double press. · The operation of the second mode is a single click, and the operation of the first mode is a double click. · The operation of the second mode is a pressing operation, and the operation of the first mode is a pulling operation. · The operation of the second mode is a pressing operation, and the operation of the first mode is a sliding operation. These are just examples, and other possibilities can also be considered.

[0107] As described in the first embodiment, the set values are a plurality of set values related to exposure, and a plurality of individual corresponding operators (F-value mode key 81, ISO mode key 82, SS mode key 84, collectively referred to as "individual corresponding keys") that individually correspond to the plurality of set values are provided as mode operators. Then, the camera control unit 30 executes switching between the auto mode and the manual mode for the corresponding set value in response to the operation of the first aspect of the individual corresponding operator, and executes switching between the unlocked state and the locked state for the corresponding set value in response to the operation of the second aspect of the individual corresponding operator. That is, in response to the operations of the F-value mode key 81, ISO mode key 82, and SS mode key 84 as individual corresponding keys, as described with reference to FIG. 6, switching between any of the auto mode and the manual mode for each of the set values of the F-value, ISO value, and SS value, and switching between the unlocked state and the locked state in the manual mode are performed. Thereby, it is possible to individually prevent unintended mode changes for each set value and individually lock set values that are not intended to be changed, which is more effective in preventing user misoperations and improving operability.

[0108] As described in the second embodiment, the set values are a plurality of set values related to exposure, and a set key 83 that collectively corresponds to the plurality of set values is provided as a mode operator. The camera control unit 30 executes batch switching between the auto mode and the manual mode for the plurality of set values in response to the operation of the first aspect of the set key 83, and executes batch switching between the unlocked state and the locked state for the plurality of set values in response to the operation of the second aspect of the set key 83. That is, as described with reference to FIG. 7, in response to the operation of the set key 83, switching between the auto mode and the manual mode and switching between the unlocked state and the locked state in the manual mode are collectively performed for each of the set values of the F-value, ISO value, and SS value. Thereby, extremely convenient operability can be provided when batch mode changes are to be made or when the set values are to be collectively maintained. Especially in situations where still image shooting is performed, the F-value, ISO value, and SS value are often changed respectively. In such cases, it is convenient to be able to switch between the auto mode and the manual mode all at once.

[0109] As described in the third embodiment, as a mode operator, there may be provided a plurality of individual corresponding operators (81, 82, 84) each corresponding individually to a plurality of setting values, and a set key 83 corresponding to the plurality of setting values all at once. In this case, the camera control unit 30 executes switching between the auto mode and the manual mode for the corresponding setting value according to the operation of the first aspect of the individual corresponding operator. Also, it executes switching between the unlocked state and the locked state for the corresponding setting value according to the operation of the second aspect of the individual corresponding operator. Further, the camera control unit 30 executes switching so that all of the plurality of setting values become the auto mode according to the operation of the first aspect of the set key 83 when some or all of the plurality of setting values are in the manual mode (see ct3 in FIGS. 8 and 7), and executes batch switching between the unlocked state and the locked state for the plurality of setting values according to the operation of the second aspect of the set key 83 when all of the plurality of setting values are in the manual mode (see ct1 and ct2 in FIGS. 8 and 7). By enabling the separate use of the individual corresponding keys (81, 82, 84) and the set key 83 in this way, the possibility of providing operability suitable for the user's use case can be increased.

[0110] In the embodiment, the camera control unit 30 is assumed to set the manual mode in the initial state. As a result, the front dial 72, the rear dial 73, the wheel 74, etc. do not become invalid states from the beginning. Since the user has to consciously set the auto mode, the user can also be aware of the invalid states of the front dial 72, etc.

[0111] In the embodiment, the camera control unit 30 is assumed to set the setting value when transitioning from the auto mode to the manual mode to the value in the immediately preceding auto mode. That is, the transition to the manual mode is made in a state where the set values automatically adjusted in the auto mode are carried over. This enables the user to finely adjust the state automatically adjusted in the auto mode to the optimal state by manual mode. However, in this case, if the auto mode and the manual mode are switched by a misoperation, the set values adjusted by the operation in the manual mode will be changed by the automatic adjustment in the auto mode. When the user returns to the manual mode, the manual operation will be performed from the changed set values in the auto mode. That is, the previously finely adjusted set values will be lost, so fine adjustment must be performed again. Therefore, as in this embodiment, it is very effective in that the state where the set values are finely adjusted is not wasted by making the mode switch by long pressing so that misoperations of mode change are less likely to occur.

[0112] In the embodiment, the set values are a plurality of set values related to exposure, and in the manual mode, it has a plurality of set value change operators assigned to correspond to certain set values. The camera control unit 30 has been given as an example of performing control to display the dial guides 53, 54, 55 indicating the set value change operators corresponding to the respective set values. This makes it easy for the user to know which of the set value change operators such as the front dial 72, the rear dial 73, and the wheel 74 correspond to the F value, the SS value, and the ISO value, respectively, improving the operability. In particular, in the imaging device 1 of the embodiment, the user may be able to customize which of the front dial 72, the rear dial 73, and the wheel 74 are assigned to the F value, the SS value, and the ISO value, respectively. In such a case, it may be unclear which of the front dial 72, the rear dial 73, and the wheel 74 the set value change operators for the F value, the SS value, and the ISO value are assigned to. Therefore, by performing a display such that the correspondence between the set values and the set value change operators is clearly visible, as in the dial guide of FIG. 12, it becomes clear what assignment settings the user has made, and it is possible to prevent the user from being confused in the operation.

Thereby, the user can arbitrarily assign the set key 83 using the custom keys C1, C2, C3, C4, and can realize the usability according to the user's preference. In particular, since the F-value mode key 81, the ISO mode key 82, the SS mode key 84, and the set key 83 can be distributed and assigned to the custom keys C1, C2, C3, C4, the usability according to the user's operation tendency can be realized.

[0116] In the embodiment, examples of the set value are given as the F-value, the shutter speed value, and the ISO value. In this case, it is possible to improve the operability of mode switching and the locked state of the F-value, the SS value, and the ISO value as the exposure setting.
