Description

  The present invention relates to an imaging device to which a photographic lens can be attached and detached, a control method therefor, a program, and a recording medium.

  Many operation switches and a display panel such as a liquid crystal display are arranged on the surface of the housing of the imaging apparatus. In recent years, some display panels have a touch panel function by displaying an icon imitating a switch on a display screen and having a contact detection function using a resistance film method or a capacitance method. Therefore, an arbitrary area on the display screen of the display panel can function as an operation switch. As described above, since there are many operation switches on the surface of the housing, there is a problem in that the user touches the operation switch unintentionally when performing some operation, resulting in an erroneous operation.

  Patent Document 1 discloses an image pickup apparatus having a touch panel type display panel provided in an image pickup apparatus main body so that the angle can be adjusted by a tilting mechanism including a hinge mechanism and the like. The imaging device of Patent Document 1 determines that the first operation is a malfunction by a user who tries to adjust the angle of the display panel erroneously operates the touch panel and detects the subsequent displacement of the display panel. The operation being executed is invalidated.

JP 2005-039582 A

  However, in the image pickup apparatus disclosed in Patent Document 1 described above, the target for preventing an erroneous operation is limited to that due to the tilting operation of the display panel. Some image pickup apparatuses have interchangeable lenses. When exchanging a photographic lens in such an interchangeable lens type imaging device, the finger or palm of the hand that contacts the side that holds the main body comes into contact with many areas on the surface of the housing, so there are touch panels and switches at this position. And misoperation. Therefore, the user may be confused because the state of the imaging device is changed to an unintended state such as the setting of the imaging device or the display screen due to an erroneous operation.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to prevent the state of the imaging apparatus from being changed by an erroneous operation when the photographing lens is replaced.

The present invention is an image pickup apparatus in which a photographic lens can be attached and detached, and when the detection means for detecting attachment and detachment of the photographic lens and at least one predetermined condition that is likely to be an erroneous operation are not satisfied, the detection is performed. In response to an operation on the operation unit by the user performed in a state where it is detected that the taking lens has been removed by the means, when corresponding processing is performed and any one of the at least one predetermined condition is satisfied, Control means for performing control so as to invalidate processing according to an operation on the operation unit performed in a state where it is detected that the photographing lens is removed by the detection means.

  According to the present invention, it is possible to prevent the state of the imaging apparatus from being changed by an erroneous operation when the photographing lens is replaced.

FIG. 1 is a diagram illustrating a schematic configuration of an imaging system. FIG. 2 is a diagram illustrating an appearance of the imaging system. FIG. 2A is a perspective view of the imaging system as viewed from the front, and FIG. 2B is a perspective view of the imaging system as viewed from the back.

The imaging system 100 includes a camera body 101 and a photographing lens 102. The imaging system 100 is an interchangeable lens type in which a photographic lens 102 can be attached to and detached from the camera body 101 via a mount unit 103.
The camera body 101 includes an imaging unit 104, an image processing unit 105, a CPU 106 as a central processing unit, a ROM 107, a memory 108, a display 109 as a display unit, an operation unit 110, a release detection unit 111, a communication unit 112, and the like. Each component of the camera body 101 is connected to each other via an internal bus. Note that the configuration of the recording medium drive, the battery, and the like is omitted.

The imaging unit 104 is an imaging element such as a CCD sensor or a CMOS sensor that converts a subject image formed through the photographing lens 102 (lens group 113) into an image signal. The imaging unit 104 transmits the converted image signal to the image processing unit 105.
The image processing unit 105 performs various image processing such as predetermined pixel interpolation, resizing processing, and color conversion on the image signal based on the control of the CPU 106. The image processing unit 105 transmits the image signal after the image processing to the memory 108 or the display 109.

The CPU 106 controls the overall operation of the camera body 101. The CPU 106 receives an operation by the user via the operation unit 110 or the like, and executes various programs described later. Further, the CPU 106 performs display control of the display 109. The CPU 106 is an example of a control unit and a determination unit.
The ROM 107 is a nonvolatile memory, and stores programs executed by the CPU 106 and various data. In addition, the ROM 107 includes start-up processing of the camera body 101, basic input / output processing, a program for realizing a flowchart described later, information on timeout times T1, T2, and T3 described later. The ROM 107 may be a rewritable nonvolatile memory.
The memory 108 is a volatile memory, and is a work area in which the CPU 106 temporarily stores data. The memory 108 stores various variables, contents of various flags, etc., which will be described later.
The display 109 displays images and display items to be described later. The display 109 constitutes a graphic user interface (GUI).

The operation unit 110 includes a plurality of switches that can be operated by the user.
As shown in FIG. 2, the operation unit 110a is a changeover switch, and can perform power ON / OFF and scene mode / photographing mode settings. The operation unit 110b is a release switch, which can be instructed to perform an autofocus operation by half-pressing and can be instructed to photograph by full-pressing. The operation unit 110c is a dial switch and can instruct the CPU 106 by a rotation operation in the circumferential direction. Further, the operation unit 110c can be provided with a cross key that can be pressed at intervals of 90 ° in the vertical and horizontal directions, for example, by combining switches that give instructions to the CPU 106 when pressed. The center of the operation unit 110c is a determination key, which instructs determination of an item selected with a cross key or the like.

The operation unit 110d is a MENU switch, and can instruct the display 109 to display a menu screen. Further, the operation units 110e to 110g are various switches, and can instruct change of items displayed on the display 109. Note that the number of switches to be arranged and the function to be assigned can be changed as appropriate.
The operation unit 110h is a resistive film type or capacitive type touch panel disposed on the surface of the display 109. By combining the display image on the display 109 and the detection area of the touch panel, the user can instruct the CPU 106 to perform various operation inputs via the operation unit 110h.

The release detection unit 111 is a sensor that detects that a later-described lock release unit 200 is pressed, and notifies the CPU 106 of the pressed information.
The communication unit 112 is electrically connected to the photographing lens 102 via the mount unit 103. The communication unit 112 transmits a control instruction to the photographing lens 102 from the camera body 101 and receives individual identification information and operation information from the photographing lens 102. The CPU 106 can detect that the photographing lens 102 is connected to the camera body 101 by receiving individual identification information and operation information from the photographing lens 102 via the communication unit 112.

The photographing lens 102 includes a lens group 113, a CPU 114, a ROM 115, a communication unit 116, and the like.
The lens group 113 includes a zoom lens, a focus lens, and the like. The lens group 113 is moved in the optical axis direction via the drive circuit based on the control of the CPU 114 or the CPU 106 of the camera body 101, thereby realizing optical zoom and autofocus.
The CPU 114 controls the operation of the entire taking lens 102. The CPU 114 transmits individual identification information and operation information of the photographing lens 102 to the camera body 101 via the communication unit 116.
The ROM 115 is a non-volatile memory and stores individual identification information such as the type (model name) and serial number of the photographing lens 102.

Next, a configuration in which the taking lens 102 is attached to and detached from the camera body 101 will be described.
As shown in FIG. 2, the camera body 101 includes a lock release unit 200, a lock unit 201, and a terminal 202. On the other hand, the photographing lens 102 has a locked portion 203 and a terminal 204.
The lock release unit 200 is a lock release operation unit that is operated when the photographing lens 102 is detached from the camera body 101. In a state where the photographic lens 102 is attached to the camera body 101, the rod-shaped lock part 201 protruding from the camera body 101 is inserted into a hole-like locked part 203 provided in the photographic lens 102, so that the photographic lens It is locked so that 102 does not rotate around the optical axis. In other words, the lock part 201 and the locked part 203 constitute a lock mechanism. When the user presses the unlocking unit 200, the locking unit 201 is immersed in the camera body 101 in conjunction with the unlocking unit 200, and the lock is released by releasing from the locked unit 203. The user can remove the photographing lens 102 from the camera body 101 by rotating the photographing lens 102 in one direction around the optical axis in the unlocked state. On the other hand, when the photographing lens 102 is brought into contact with the mount portion 103 of the camera body 101 and rotated in the other direction around the optical axis, the lock portion 201 is automatically inserted into the locked portion 203, and the photographing lens 102 is attached to the camera. It can be attached to the main body 101. When the photographic lens 102 is attached, the user does not need to press the lock release unit 200.

  Note that the unlocking unit 200 is biased to protrude from the camera body 101. Therefore, the lock release unit 200 is immersed in the camera body 101 when the user presses against the bias. Therefore, when the user releases the operation against the urging, the unlocking unit 200 protrudes from the camera body 101 again. The release detection unit 111 described above detects the press of the lock release unit 200 and notifies the CPU 106 of information indicating that the lock release unit 200 has been pressed. The release detection unit 111 is an example of a detection unit.

The terminal 202 of the camera body 101 and the terminal 204 of the photographing lens 102 are connected when the photographing lens 102 is attached to the camera body 101, and the connection is released when the photographing lens 102 is detached from the camera body 101.
Note that the above-described lock release unit 200 is not limited to the configuration in which the lock is released by pressing, but may be configured to release the lock by an operation such as sliding or pulling.

Next, an erroneous operation preventing process for preventing an erroneous operation when the user replaces the taking lens 102 mounted on the camera body 101 will be described.
FIG. 3 is a timing chart showing processing of the camera body 101 before and after the user exchanges lenses. Here, the horizontal axis direction from left to right represents the passage of time t, and the vertical axis represents detection results (a) to (d) and control results (e) and (f).

(A) in the uppermost row is a lock release unit detection flag indicating a detection result of pressing of the lock release unit 200. The upper position is a period during which the unlocking unit 200 is pressed, and is a state in which the unlocking unit detection flag is set. The lower position is a period in which the unlocking unit 200 is not pressed, and the unlocking unit detection flag is cleared. Information on setting or clearing the unlocking unit detection flag is stored in the memory 108.
The second level (b) is a lock release unit history flag indicating a history of pressing of the lock release unit 200. The upper position is a state where the unlocking unit history flag is set, and the lower position is a state where it is cleared. Information on setting or clearing the unlocking unit history flag is stored in the memory 108.

  The third level (c) is a lens mounting flag indicating a result of detecting whether the taking lens 102 is attached or detached. The upper position is a period during which the mounting of the taking lens 102 is detected, and is a state in which the lens mounting flag is set. The lower position is a period during which the mounting of the taking lens 102 is not detected, and is a state in which the lens mounting flag is cleared. Attachment / detachment of the taking lens 102 is detected by the CPU 106. Specifically, the CPU 106 detects whether the photographing lens 102 is attached or detached by notifying the CPU 106 whether or not the communication unit 112 of the camera body 101 can communicate with the communication unit 116 of the photographing lens 102. Note that the method for detecting attachment / detachment of the photographing lens 102 is not limited to this case, and other methods may be used. Information on setting or clearing the lens mounting flag is stored in the memory 108.

The fourth row (d) shows the operation detection result for the operation unit 110. The operation unit 110 includes operation units 110 (a) to (h) illustrated in FIG. Note that the operation on the operation unit 110 includes pressing, sliding, rotation, and the like depending on the operating unit 110, and the following description will be made by taking up pressing. The upper position is a period during which pressing of the operation unit 110 is detected, and the lower position is a period during which pressing of the operation unit 110 is not detected. Pressing of the operation unit 110 is detected by the CPU 106.
Since the CPU 106 detects or is notified of the detection results (a) to (d), the CPU 106 determines whether to accept the operation unit 110 and the control content of the return process according to the content of the detection result.

  The fifth row (e) shows the result of acceptability for pressing of the operation unit 110. The upper position is a period in which the process assigned to the pressed operation unit 110 is executed, and the lower position is a period in which the process corresponding to the operation unit 110 is not executed. Here, for example, a case where processing is performed at a release timing after the operation unit 110 is pressed is shown. In the lower position, the operation result is not necessarily received during the period in which the operation unit 110 is not detected in the fourth detection result (d), but the operation unit 110 is detected to be pressed. Nevertheless, the operation may not be accepted, which will be described later.

  The sixth level (f) is a determination result as to whether or not to perform a restoration process for restoring the state of the camera body 101. The restoration process is to return the state of the camera body 101 such as the setting contents of the camera body 101 and the display contents of the display 109 to the state before the user starts the work of removing the photographing lens 102. The control of the return process will be described later.

Next, description will be made in order along the operations “A” to “I” corresponding to the detection result (d) of pressing of the operation unit 110 in the fourth row. Here, the switch is described as a switch unless the operation unit 110 is specified in particular, but the same applies to a function switch displayed on the touch panel.
The operations “A” and “B” are operations in a state where the unlocking unit 200 is not pressed and the photographing lens 102 is attached. The operation “A” and the operation “B” are different in the length of time that the switch is continuously pressed. Therefore, when the operation input contents differ depending on the length of time, the CPU 106 shifts to the long press mode while the switch is continuously pressed in the operation “B”. Note that whether or not each switch corresponds to a long press is arbitrary. Moreover, the description regarding the difference between short press and long press control is omitted.
The CPU 106 receives the operation “A” and the operation “B” as a normal operation, and executes processing according to the operation “A” and the operation “B”. Accordingly, the CPU 106 changes the state of the camera body 101 by changing the settings of the camera body 101 or the display content of the display 109, for example.

The operation “C” is an operation performed when the lock release unit 200 is pressed while the switch is pressed. Here, the detection result (c) of the third stage detects the mounting of the taking lens 102, but it may be detected that the taking lens 102 is detached. It is not limited.
When it is detected that the lock release unit 200 is pressed, the CPU 106 does not accept the operation “C” and does not execute the process corresponding to the operation “C”. This is because it is not a general handling method to start the operation of removing the photographing lens 102 even though the user is pressing the switch. It is because it can be judged that it is not. Therefore, in the operation of removing the photographing lens 102, it can be estimated that the operation “C” is an erroneous operation in which the hand for holding the camera body 101 has touched the switch.
When the switch is pressed for a long time and the mode is changed to the long press mode, the display content of the display 109 may be changed. In this case, the CPU 106 returns the state of the camera body 101 to the state before accepting the operation “C” at the time when the depression of the lock release unit 200 is detected.

The operation “D” and the operation “E” are operations performed while the lock release unit 200 is being pressed. The operation “D” and the operation “E” are different depending on whether the release timing of the switch is before or after the lock release unit 200 is released. In any case, when the depression of the unlocking unit 200 is detected, the CPU 106 does not accept the operation “D” and the operation “E”, and does not execute the process according to the operation “D” and the operation “E”. . That is, when the operation “D” or the operation “E” is the first operation after the lock release unit 200 is pressed, the CPU 106 does not accept the operation “D” and the operation “E”, thereby Neither setting nor display content of the display 109 is changed. This is because the user is working to remove the taking lens 102 because the lock release unit 200 is pressed, and the operations “D” and “E” are not operations intended by the user. This is because it can be judged. Therefore, in the operation of removing the photographing lens 102, it can be estimated that the operation “D” and the operation “E” are erroneous operations that have touched the switch.
Even if the operation “C” is performed immediately before and the operations “D” and “E” are performed thereafter, the CPU 106 performs the return processing as described above, and thus the state of the camera body 101 is determined. Is the same as before the lock release unit 200 is pressed.

The operation “F” is the first operation after the taking lens 102 is removed and the unlocking unit 200 is released. If the CPU 106 detects that the taking lens 102 has been removed and satisfies a predetermined condition, the CPU 106 does not execute a process corresponding to the operation “F”. That is, the operation “F” is an intentional operation while recognizing that the operation is an erroneous operation by the hand that has been holding the camera body 101 after the photographing lens 102 is removed and that the photographing lens 102 is not attached. There may be cases where Therefore, the CPU 106 determines whether the operation is an erroneous operation or an intentional operation by determining whether or not a predetermined condition is satisfied.
Specifically, the CPU 106 executes a process corresponding to the operation “F” and measures an elapsed time from the operation “F” with the timer Tsw. The CPU 106 refers to the timer Tsw to determine whether or not the next operation has been performed during a predetermined timeout time T1. When the next operation is longer than the timeout time T1, the CPU 106 executes a process for restoring the setting contents of the camera body 101 and the display contents of the display 109. Here, the CPU 106 does not substantially execute the process corresponding to the operation “F” and the next operation subsequent to the operation “F” by returning to the state before executing the process corresponding to the operation “F”. .
This can be determined to be an intentional operation when the next operation is performed at a certain interval time, and if the next operation is not performed for a predetermined time, the previous operation is an erroneous operation. It is because it can be judged that there exists. Therefore, it is preferable that the timeout time T1 is a time that does not cause a problem even for a person who operates slowly.

The operation “G” is the next operation performed within the timeout time T1 (within a predetermined time) from the operation “F”. Even if the operation “G” is performed within the timeout period T1, if the operation “G” is not an operation related to the operation “F”, the operation “F” and the operation “G” may be erroneous operations. is there. Therefore, the CPU 106 determines whether the operation is an erroneous operation or an intentional operation by determining whether or not a predetermined condition is satisfied.
Specifically, the CPU 106 determines whether or not a function is assigned to the operation unit 110 corresponding to the operation “G”. If the function is assigned, the CPU 106 executes processing corresponding to the operation “G”. On the other hand, if not assigned, the CPU 106 executes the return process without accepting the operation “G”. Here, the CPU 106 returns to the state before executing the process corresponding to the operation “F”, so that the process corresponding to the operation “F” and the operation “G” is not substantially executed.
Further, FIG. 3 illustrates the case where the operation “G” is performed only once. However, for example, when a plurality of operations are necessary on the menu screen, the CPU 106 repeatedly determines each operation.

This is because a series of operations can be determined to be intentional operations when operations related to the operation “F” are continuously performed, and when an operation unit 110 to which no function is assigned is operated. This is because the operation “G” is not intended and can be determined to be an erroneous operation.
Note that the operation unit 110 to which no function is assigned refers to a switch that becomes invalid during a specific operation or an area to which no function is assigned on the touch panel. In the area to which no function is assigned on the touch panel, even if the position is pressed in a normal state such as an invalid switch area displayed in gray out or a corner to which no GUI is originally assigned, the CPU 106 can Includes areas that do not change state.

Further, when the user releases the lock release unit 200, the CPU 106 starts measuring the timer Tlock from that point. The timer Tlock is used for comparison with the following two predetermined times.
The first is a timeout time T2 related to the remounting time of the taking lens 102. Specifically, the CPU 106 performs a return process when it is detected that the photographing lens 102 is attached within the time-out period T2 after the unlocking unit 200 is released.
This is because the user may accidentally wear a photographing lens or the like that does not have a communication function while the wearing of the photographing lens 102 is not detected. In this case, the CPU 106 cannot detect the mounting of the taking lens via the communication unit 112. On the other hand, the user makes settings for the photographing lens having no communication function in the camera body 101 via the operation unit 110. In this case, when the user wears the photographing lens 102 having the communication function within the timeout time T2, the CPU 106 performs a restoration process in order to cancel the setting contents set for the photographing lens having no communication function.

The second is a timeout time T3 related to the entire process described above. Specifically, when the CPU 106 cannot detect the mounting of the photographing lens 102 within the timeout time T3 after the unlocking unit 200 is released, the CPU 106 then presses the operation unit 110 in the same manner as in normal times. Return to the process of accepting. Therefore, the CPU 106 accepts the operation “H” as a short press similar to the operation “A”, and accepts the operation “I” as a long press like the operation “B”. As described above, the CPU 106 executes the return process when the predetermined condition described above is satisfied within the timeout time T3.
Here, the timeout time T3 is set to a time longer than the timeout time T2.

Next, processing of the camera body will be described with reference to the flowcharts of FIGS.
FIG. 4 is a main flowchart showing the processing of the timing chart of FIG. 5 to 9 are flowcharts showing the detailed processing of FIG. FIG. 8 and FIG. 9 are a series of flowcharts connected at portions 1 to 3. The processing in the flowcharts of FIGS. 4 to 9 is realized by the CPU 106 developing and executing a program stored in the ROM 107 in the memory 108.

Hereinafter, each of the operations “A” to “G” illustrated in FIG. 3 will be described with reference to each flowchart. In the following description of the flowchart, the operation unit 110 is a switch unless otherwise specified, an operation on the operation unit 110 is referred to as pressing, and a release of the operation on the operation unit 110 is referred to as release.
The operations “A” to “G” are each composed of the following three items (1) to (3), and the CPU 106 executes the main flowchart shown in FIG. To do.
(1) When the switch is pressed (2) When an event occurs while the switch is pressed (3) When the switch is released Here, the item (2) does not generate an event Or, conversely, an event may occur multiple times. Although omitted in the flowchart of FIG. 4, it is assumed that initialization of various flags and timers has been appropriately completed.

First, the processing of “(1) When the switch is pressed” in the operations “A” and “B” will be described.
In S401, the CPU 106 compares a timer Tlock that measures an elapsed time after the unlocking unit 200 is released with a timeout time T3 after the unlocking unit 200 is released. Here, since the measurement of the timer Tlock is not started, the timer Tlock is the initialization value “0”, and the process proceeds to S403 because the condition is not satisfied. A process that satisfies this condition will be described later.

In S403, the CPU 106 performs a lock release unit detection process. Specifically, this will be described with reference to the flowchart of FIG.
In step S <b> 501, the CPU 106 determines whether the lock release unit 200 is pressed via the release detection unit 111. Here, since it has not been pressed, the process proceeds to S503, and the CPU 106 checks whether or not the lock release unit detection flag is set. Here, since it is not set, the process proceeds to S505, and the CPU 106 clears the lock release unit detection flag. If the unlocking unit detection flag has already been cleared, the CPU 106 may omit S505 or clear it again in S505. Thereafter, the process returns to the flowchart of FIG.

Next, in S404, the CPU 106 performs lens attachment / detachment detection processing. Specifically, this will be described with reference to the flowchart of FIG.
In step S <b> 601, the CPU 106 determines whether the photographing lens 102 is attached via the communication unit 112. If it is mounted, the process proceeds to S602, and the CPU 106 checks whether the lens mounting flag has already been set. This process is for confirming whether the result is the same as the previous routine process. Here, since the lens mounting flag is set, S603 and S604 are omitted, and the process proceeds to S605. In S605, the CPU 106 sets a lens mounting flag. Similar to the process of clearing the unlocking unit detection flag, the CPU 106 may set or clear all the flags so as to overlap the existing state. Next, in S606 and S607, the CPU 106 resets the timer Tlock and the timer Tsw to “0”. Thereafter, the process returns to the flowchart of FIG.

Next, in S405, the CPU 106 determines whether the switch is pressed. Here, since it has been pressed, the process proceeds to S406, and the CPU 106 performs a process when the switch is pressed. Specifically, this will be described with reference to the flowchart of FIG.
First, in S701, the CPU 106 assigns “1” to the variable SWnow to indicate that the switch has been pressed this time. In step S <b> 702, the CPU 106 collates the previous variable SWnow with the variable SWlast that is the previous switch press detection result. Here, since “0” is assigned to the variable SWlast, the variable SWnow does not match the variable SWlast. Based on this result, the CPU 106 can determine that the switch has been newly pressed this time. Therefore, in S703, the CPU 106 starts measuring a timer Ton that measures the switch pressing duration. In step S <b> 704, the CPU 106 checks the current value of the timer Tsw and determines whether the timer Tsw is “0”. Here, since the timer Tsw has been reset to “0” in S607, the process proceeds to S705, where the CPU 106 stores various setting contents of the camera body 101 and display contents of the display 109 in the memory 108, that is, the state of the camera body 101 is changed. Back up. The backed up content is used for return processing. In S708, the CPU 106 checks whether the unlocking unit detection flag is set. Here, since the unlocking part detection flag is cleared in S505, S709 is omitted and the process proceeds to S710. In S710, the CPU 106 substitutes “1” for the variable SWlast. Thereafter, the process returns to the top of the flowchart of FIG.

Next, the processing of “(2) When an event occurs while the switch is being pressed” in the operations “A” and “B” will be described. S401 is the same as the process described above. In the operation “A” and the operation “B”, the state of the lock release unit 200 and the state in which the photographing lens 102 is attached continue without change. Therefore, the unlocking part detection process in S403 and the lens attachment / detachment detection process in S404 are exactly the same as “(1) When the switch is pressed”.
Next, in S405, since the CPU 106 determines that the switch is pressed, the process proceeds to S406 when the switch is pressed, that is, S701 in FIG.

Here, the description will focus on processing that is different from the previous processing.
In S702, the CPU 106 compares the variable SWnow with the variable SWlast, and since both are “1”, the process proceeds to S706. In S706, the CPU 106 determines whether or not the timer Ton has exceeded a predetermined time. When branching in the determination of this process, the operation “A” is different from the operation “B”. That is, while the switch is continuously pressed, the flowchart of FIG. 4 is repeated several times along the same route, and the case where the switch is released before the condition of S706 is satisfied is the short press of the operation “A”. The case where the above condition is satisfied is the long press of the operation “B”. Therefore, if the condition of S706 is satisfied, the process proceeds to S707, and the CPU 106 shifts to the long press mode. Next, S708 and S710 are the same as those described above.

  Next, the processing of “(3) When the switch is released” in the operations “A” and “B” will be described. S401, S403, and S404 are the same as the above-described processes of “(1) When a switch is pressed” and “(2) When an event occurs while the switch is pressed”. Next, in S405, the CPU 106 determines that the switch has not been pressed, and proceeds to S407.

In S407, the CPU 106 performs a switch release process. Specifically, this will be described with reference to the flowchart of FIG.
In S <b> 801, the CPU 106 substitutes “0” for the variable SWnow to indicate that the switch has not been pressed this time. Next, in S802, the CPU 106 collates the variable SWnow with the variable SWlast. Here, since “1” is assigned to the variable SWlast, they do not match. Based on this result, the CPU 106 can determine that the switch has been newly released this time. In step S803, the CPU 106 stops measuring the timer Ton and resets it to “0”. Next, in S804, the CPU 106 determines whether or not the unlocking unit detection flag is set. Here, since the unlocking unit detection flag is not set, the process proceeds to S805. In S805, the CPU 106 determines whether or not the unlocking unit history flag is set. Here, since the unlocking unit history flag is not set, the process proceeds to S806. In S806, the CPU 106 determines whether or not the lens mounting flag is set. Here, since the lens mounting flag is set, the process proceeds to S901. As shown in FIG. 8, when the determination of the three flags is different from this time, the CPU 106 executes different processing without determining the next flag. The different processing will be described later in the description of another operation.

  In step S <b> 901, the CPU 106 branches the process to be performed next according to the function of the pressed switch. In the case of the MENU switch, the process advances to step S902, and the CPU 106 displays a menu screen for setting the camera body 101 on the display 109. In the case of the selection key, the process proceeds to S903, and the CPU 106 determines the instruction according to the function assigned to the selection key. Here, the selection key is, for example, a switch to which a function is independently assigned to a touch panel or the like. In the case of the cross key, the process advances to step S904, and the CPU 106 displays the cursor and the selection frame displayed on the display 109 so as to move in the same direction as the direction of the cross key. In the case of the determination key, the process proceeds to S905, and the CPU 106 determines the information assigned to the location indicated by the cursor or selection frame displayed on the display 109.

When any one of the selection key, the cross key, and the determination key is pressed, the CPU 106 determines whether or not any setting related to the camera body 101 is completed by pressing the switch in S906. When the setting is completed, the process proceeds to S907 and S908, and the CPU 106 resets the timer Tlock and the timer Tsw. The meaning of these processes will be described later in operation “G”. For example, in the case of the cross key, only the cursor displayed on the display 109 moves, and the settings relating to the camera body 101 are not completed. Therefore, when the setting of the camera body 101 is not completed, the CPU 106 omits S907 and S908. In the case of the operation unit 110 to which no function is assigned, since there is no specific process that the CPU 106 should execute, the process proceeds to S909. Although a method in which the CPU 106 does not perform the switch operation acceptance process when the operation unit 110 to which no function is assigned is pressed is considered, it is not taken up in this embodiment. Since the operation unit 110 to which no function is assigned has already been described above, description thereof is omitted. It should be noted that the switches listed above are examples, and it is preferable that optimal branches corresponding to the functions of the switches are appropriately prepared for other switches.
Next, in S909, the CPU 106 substitutes “0” for SWlast. Thereafter, the process returns to the top of the flowchart of FIG.

  Thus, the processing of the camera body 101 regarding the operation “A” and the operation “B” is completed. In addition, since the operations described below are common to many of the processes described above, different processes will be mainly described. In the following description, the long press is not referred to, but in any operation, when the timer Ton is a press that exceeds a predetermined time, the routine of the operation “B” is appropriately inserted.

  Next, the process “(1) when the switch is pressed” in the operation “C” is the same as the process “when the switch (1) is pressed” in the operation “A”. Therefore, in the switch depression process in S406, in S705, the CPU 106 backs up the various setting contents of the camera body 101 and the display contents of the display 109 in the memory 108. The contents backed up here are used for a return process of “(3) When the switch is released” of the operation “C” described later.

  Next, the processing of “(2) When an event occurs while the switch is being pressed” in the operation “C” will be described. Here, the lock release unit 200 is pressed. Therefore, in the unlocking unit detection process of S403, in S501, the CPU 106 determines that the unlocking unit 200 is pressed, and proceeds to S502. In S502, the CPU 106 sets a lock release unit detection flag. Then, it progresses to S404, S405, S406. In the switch depression process in S406, in S702, the CPU 106 determines that the variable SWnow and the variable SWlast are the same “1”, and proceeds to S706. In S706, the CPU 106 performs processing according to the length of the pressing duration. Next, in S708, the CPU 106 determines that the lock release unit detection flag is set, and proceeds to S709. In S709, the CPU 106 sets a lock release unit history flag. Next, in S710, the CPU 106 substitutes “1” for the variable SWlast. Thereafter, the process returns to the top of the flowchart of FIG.

Next, the processing “(3) When the switch is released” in the operation “C” will be described. Here, S401, S403, and S404 are the same as the processing of the operation “C” “when an event occurs while the switch (2) is being pressed”. Next, in S405, since the CPU 106 determines that the switch is not pressed, the process proceeds to S407. In the switch release processing in S407, since the switch is newly released, the process proceeds to S801, S802, S803, and S804. In S804, the CPU 106 determines that the lock release unit detection flag is set, and proceeds to S814. In S814, the CPU 106 clears the lock release unit history flag. Next, in step S816, the CPU 106 restores the various setting contents of the camera body 101 and the display contents of the display 109 to the state backed up in the memory 108 in step S705 of the operation “C” “when the (1) switch is pressed”. Perform recovery processing. Next, in S909, the CPU 106 substitutes “0” for the variable SWlast. Thereafter, the process returns to the top of the flowchart of FIG.
That is, when the unlocking unit 200 is pressed while the switch is pressed, as in the operation “C”, the process corresponding to the operation “C” is performed regardless of whether the photographic lens 102 is attached or detached. Not executed. Furthermore, the state of the camera body 101 is returned to the state immediately before the operation “C”, specifically, the state “when the (1) switch is pressed” of the operation “C”.

  Next, the processing of “(1) When the switch is pressed” in the operation “D” will be described. Here, the processing up to S401, S403, S404, S405, and S406 is the same as the processing of “when an event occurs while the switch is being pressed” in the operation “C”. In the switch pressing process in S406, in S702, the CPU 106 determines that the variable SWnow is different from the variable SWlast this time, and proceeds to S703, S704, and S705. In step S <b> 705, the CPU 106 backs up various setting contents of the camera body 101 and display contents of the display 109 in the memory 108. The contents backed up here are used for a return process of “(3) When the switch is released” in operation “D” described later. Next, in S708, the CPU 106 determines that the lock release unit detection flag is set, and proceeds to S709. In S709, the CPU 106 sets a lock release unit history flag. In S710, the CPU 106 substitutes “1” for the variable SWlast. Thereafter, the process returns to the top of the flowchart of FIG.

Next, the process of “(2) When an event occurs while the switch is being pressed” in the operation “D” will be described. Here, no event occurs, so no processing is performed.
Next, the processing “(3) When the switch is released” in the operation “D” will be described. This process is the same as the process “(3) When the switch is released” of the operation “C” described above. Therefore, in the switch release processing of S407, in S816, the CPU 106 stores the various setting contents of the camera body 101 and the display contents of the display 109 in S705 of the operation “D” “(1) When the switch is pressed”. A return process for returning to the backed up state is performed at 108.
That is, when the switch is pressed while the lock release unit 200 is pressed as in the operation “D”, the process corresponding to the operation “D” is performed regardless of whether the photographic lens 102 is attached or detached. Not executed. Further, the state of the camera body 101 is returned to the state immediately before the operation “D”, specifically, the state “when the (1) switch is pressed” of the operation “D”.

Next, the processing of “(1) When the switch is pressed” in the operation “E” will be described. This process is the same as the above-described process “D” when “(1) switch is pressed”. Therefore, in the switch depression process in S406, in S705, the CPU 106 backs up the various setting contents of the camera body 101 and the display contents of the display 109 in the memory 108. The contents backed up here are used for the return process of “(3) When the switch is released” of the operation “E” described later.
Next, the process of “(2) When an event occurs while the switch is being pressed” in the operation “E” will be described. Here, since there are two events when the taking lens 102 is removed and when the unlocking unit 200 is released, each event will be described with reference to the flowchart of FIG.
First, the case where the taking lens 102 is removed will be described. In this case, a change occurs in the lens attachment / detachment detection process in S404. That is, in the lens attachment / detachment detection process in S404, in S601, the CPU 106 determines that the photographing lens 102 is not attached, and proceeds to S608. In S608, the CPU 106 clears the lens mounting flag. Then, it progresses to S405 and S406. The process at the time of pressing the switch in S406 is the same as the process of “(2) When an event occurs while the switch is being pressed” of the operation “C”. Therefore, in S709, the CPU 106 sets the unlocking unit history flag.

  Next, a case where the lock release unit 200 is released will be described. In this case, a change occurs in the unlocking unit detection process in S403. In S501, the CPU 106 determines that the unlocking unit 200 has not been pressed, and proceeds to S503. In S503, the CPU 106 determines that the lock release unit detection flag is set, and proceeds to S504. In S504, the CPU 106 starts measuring the timer Tlock. In S505, the CPU 106 clears the lock release unit detection flag. Returning to the flowchart of FIG. 4, the lens attachment / detachment detection processing in S <b> 404 is the same as the processing when the photographing lens 102 is removed because the photographing lens 102 is detached. In the process of pressing the switch in S406, the CPU 106 determines that the variable SWnow and the variable SWlast match, and thus proceeds to S706 and S708. In S708, the CPU 106 determines that the lock release unit detection flag has been cleared, skips S709, and proceeds to S710. In S710, the CPU 106 substitutes “1” for the variable SWlast. Thereafter, the process returns to the top of the flowchart of FIG.

Next, the processing “(3) When the switch is released” in the operation “E” will be described. Here, in steps S403 and S404, when the photographing lens 102 is removed when the operation “E” “when an event occurs while the switch (2) is being pressed” and the unlocking unit 200 is released. The processing in each case is the same. Next, the process proceeds to S407 via S405. In the switch release processing of S407, the process proceeds to S801, S802, S803, and S804. In S804, the CPU 106 determines that the lock release unit detection flag is not set, and proceeds to S805. In S805, the CPU 106 determines that the unlocking unit history flag is set, and proceeds to S814. In S814, the CPU 106 clears the set unlocking unit history flag. Next, in S816, the CPU 106 restores the various setting contents of the camera main body 101 and the display contents of the display 109 to the state backed up in the memory 108 in S705 of “when the (1) switch is pressed” of the operation “E”. Perform recovery processing.
That is, when the switch is pressed and the unlocking unit 200 is released and the taking lens 102 is removed as in the operation “E”, the process corresponding to the operation “E” is not executed. Further, the state of the camera body 101 is returned to the state immediately before the operation “E”, specifically, the state “when the (1) switch is pressed” of the operation “E”.

  Next, the processing of “(1) When the switch is pressed” in the operation “F” will be described. Here, S403 and S404 are the same as the processing of “(3) When the switch is released” of the operation “E”. That is, in the unlocking unit detection process in S403, the process proceeds to S501, S503, and S505. In S505, the CPU 106 clears the lock release unit detection flag. In the lens attachment / detachment detection process in S404, the process proceeds to S601 and S608. In S608, the CPU 106 clears the lens mounting flag. The unlocking unit history flag is cleared. Next, in the switch depression process at S406, the process proceeds to S701, S702, S703, S704, and S705. In step S <b> 705, the CPU 106 backs up various setting contents of the camera body 101 and display contents of the display 109 in the memory 108. The contents backed up here are used for a return process of “(3) When switch is released” of operation “F” or operation “G” described later. Then, it progresses to S708 and S710. In S710, the CPU 106 substitutes “1” for the variable SWlast. Thereafter, the process returns to the top of the flowchart of FIG. At this point, all three flags are cleared.

Next, the processing of “(2) When an event occurs while the switch is being pressed” in the operation “F” will be described. Here, no event occurs, so no processing is performed.
Next, the processing of “(3) When the switch is released” in the operation “F” will be described. Here, S403 and S404 are the same as the processing of “when (1) switch is pressed” of operation “F”. Next, in the switch release processing of S407, the process proceeds to S801, S802, S803, and S804. At this point, since all the three flags are cleared, in S804, the CPU 106 determines that the lock release unit detection flag is not set, and proceeds to S805. In S805, the CPU 106 determines that the unlocking unit history flag is not set, and proceeds to S806. In S806, the CPU 106 determines that the lens mounting flag is not set, and proceeds to S807.

In S807, the CPU 106 determines whether or not the timer Tlock is greater than 0 and less than the timeout time T3. Here, the timer Tlock is not “0” because it measures the time from when the unlocking unit 200 is released in S504 of the operation “E”. Also, the timeout time T3 has not been reached. Therefore, the CPU 106 determines that the condition of S807 is satisfied, and proceeds to S810.
In S810, the CPU 106 determines whether or not a function is assigned to the switch corresponding to the operation “F”. In the case of a switch to which a function is assigned, the process proceeds to S811, and the CPU 106 determines whether or not the timer Tsw is 0. Here, since the timer Tsw is 0, the process proceeds to S813. In step S813, the CPU 106 starts measuring a timer Tsw indicating the elapsed time since the switch corresponding to the operation “F” is released this time. Thereafter, the processing proceeds to S901 and the subsequent steps, and the CPU 106 performs processing according to the function of the switch and returns to the flowchart of FIG.
That is, when a switch to which a function is assigned is pressed with the taking lens 102 removed, processing corresponding to the function of the switch is performed.

On the other hand, in S810, in the case of a switch to which no function is assigned, the process proceeds to S815, and the CPU 106 resets the timer Tsw to “0”. Next, in S816, the CPU 106 restores the various setting contents of the camera body 101 and the display contents of the display 109 to the state backed up in the memory 108 in S705 of the operation “F” “when the (1) switch is pressed”. Perform recovery processing.
That is, when a switch to which a function is not assigned is pressed with the photographic lens 102 removed, the camera body 101 is in the state “when the (1) switch is pressed” in the operation “F”. Returned to Therefore, here, the state of the camera body 101 does not change.

Next, the process of the operation “G” will be described. The operation “G” is a routine that occurs only when the setting is not completed in S906 in “(3) When the switch is released” of the operation “F”.
First, the processing of “(1) When the switch is pressed” in the operation “G” will be described. Here, S403 and S404 are the same as the processing of “(3) When the switch is released” of the operation “E”. That is, in the unlocking unit detection process in S403, the process proceeds to S501, S503, and S505. In S505, the CPU 106 clears the lock release unit detection flag. In the lens attachment / detachment detection process in S404, the process proceeds to S601 and S608. In S608, the CPU 106 clears the lens mounting flag. The unlocking unit history flag is cleared. Next, in the switch depression process at S406, the process proceeds to S701, S702, S703, and S704. In S704, since the measurement of the timer Tsw is started in S813 of the operation “G”, the CPU 106 determines that the timer Tsw is not “0”, omits S705, and proceeds to S708 and S710. Return to the flowchart. That is, since S705 is omitted, the backed up information remains the contents stored in S705 in the switch pressing process of S406 of “(1) When the switch is pressed” of the operation “F”.

Next, the processing of “(2) When an event occurs while the switch is being pressed” in the operation “G” will be described. Here, no event occurs, so no processing is performed.
Next, the processing of “(3) When the switch is released” in the operation “G” will be described. Here, it is the same as the processing of “(3) When the switch is released” of the operation “F”. That is, in the switch release processing of S407, the process proceeds to S801, S802, S803, S804, S805, S806, S807, and S810. If the CPU 106 determines in step S810 that no function is assigned to the switch corresponding to the operation “G”, the process proceeds to steps S815 and S816. In S <b> 816, the CPU 106 performs a return process for returning the various setting contents of the camera body 101 and the display contents of the display 109 to the backed up state. At this time, since “(1) when the switch is pressed” of the operation “G” is not backed up, S705 in the switch pressing process in S406 of “(1) when the switch is pressed” of the operation “F”. It will return to the state memorized.

  On the other hand, in step S810, if the switch is assigned with a function, the process advances to step S811, and the CPU 106 determines whether the timer Tsw is “0”. Here, in the switch release processing of S407 in FIG. 4 of the operation “F”, since the measurement of the timer Tsw is started in S813, the timer Tsw is not “0” and the process proceeds to S812. In S812, the CPU 106 resets the timer Tsw to “0”. In S813, the CPU 106 starts measuring the timer Tsw indicating the elapsed time after the switch is released again. Therefore, the elapsed time since the switch was newly released this time is measured.

  Thereafter, the process proceeds to S901 and subsequent steps, and the CPU 106 performs a process according to the function of the switch. In step S <b> 906, the CPU 106 determines whether any setting related to the camera body 101 has been completed. When the setting is completed, the process proceeds to S907 and S908, and the CPU 106 resets the timer Tlock and the timer Tsw to “0”. This process is for stopping three timeout processes described later.

  That is, here, it is assumed that the next operation “G” is performed after the setting is completed by the operation “G” in a state where the photographing lens 102 is detached. In this case, the process proceeds to S801, S802, S803, S804, S805, S806, and S807 in the switch release processing in S407 of “(3) When the switch is released” of the next operation “G”. In S807, the CPU 106 determines whether or not the timer Tlock is larger than 0 and less than the timeout time T3. Since the timer Tlock is reset to 0, the CPU 106 does not proceed to S810 but proceeds to S808. Here, not proceeding to S810 means that the return process in S816 and the measurement of the timer Tsw in S813 are not started. Therefore, in S817, which will be described later, the timer Tsw does not become larger than the timeout time T1, so there is no element that proceeds to the return process. Therefore, when the setting is completed by the operation “F” or the operation “G”, the CPU 106 performs the next operation “G” similarly to the operation “A” or the operation “B” even if the photographing lens 102 is detached. ”Is executed. Note that when the setting is completed as described later, the return processing using the timeout times T2 and T3 is not performed.

On the other hand, if the setting is not completed in S906, the user repeats the next operation “G”. In this case, while the measurement of the timer Tsw is continued, it is determined that the timer Tsw is not “0” in S704 in the switch pressing process in S406, and thus S705 is omitted. Therefore, while the setting is not completed, the backed up information remains the contents stored in S705 in the switch pressing process in S406 of “(1) When the switch is pressed” of the operation “F”.
That is, when the setting is not completed but the operation “F” to which the function is assigned continues from the operation “G”, processing according to the function of the switch is performed. On the other hand, when there is an operation “G” of a switch to which no function is assigned among consecutive operations “G”, the state of the camera body 101 is the operation “F” when the “(1) switch is pressed. ”Is restored.

Next, three timeout processes will be described.
The first is processing using a timeout time T1 (first predetermined time). Here, when a new operation is not performed within the time-out time T1 after the operation “F” or the operation “G”, the operation “F” is pressed for various setting contents of the camera body 101 and the display contents of the display 109. Return processing is performed to return to the state immediately before starting.
Specifically, in the flowchart of FIG. 4, the process proceeds to S401, S403, S404, and S405. Here, since the state where the switch is not pressed is continued, in S405, the CPU 106 determines that the switch is not pressed, and proceeds to S407. In the switch release processing of S407, the process proceeds to S801 and S802. In S802, the CPU 106 collates the variable SWnow with the variable SWlast. Here, since “0” is assigned to the variable SWlast, the values coincide with each other, and the process proceeds to S817. In S817, the CPU 106 determines whether or not the timer Tsw is larger (longer) than the timeout time T1. When the timer Tsw is not greater than the timeout time T1, the process returns to the flowchart of FIG. 4, and when the timer Tsw is greater than the timeout time T1, the process proceeds to S815.

In S815, the CPU 106 resets the timer Tsw to “0”. In step S <b> 816, the CPU 106 performs a return process for returning the various setting contents of the camera body 101 and the display contents of the display 109 to the backed up state. Therefore, the state stored in S705 in the switch pressing process in S406 of “(1) When the switch is pressed” of the operation “F” stored in the memory 108 is restored.
That is, when the interval time between successive operations is longer than the time-out time T1 from the first operation until the setting of the camera body 101 is completed with the taking lens 102 removed, It can be determined that the previous operation is an erroneous operation. Therefore, by returning the state of the camera body 101 immediately before the first operation, it is possible to prevent the state of the camera body 101 from being changed due to an erroneous operation. As described above, when the setting of the camera body 101 is completed, the process corresponding to the operation “G” after the setting is completed is executed even when the photographing lens 102 is removed. Convenience can be improved.

The second is processing using a timeout time T2 (second predetermined time). Here, when the state is changed from the state where the mounting of the photographing lens 102 is not detected within the timeout time T2 after the unlocking unit 200 is released, the return processing is performed.
Specifically, in the flowchart of FIG. 4, the process proceeds to S401, S403, and S404. In the lens attachment / detachment detection process in S404, the process proceeds to S601 and S602. Here, the lens mounting flag is not set in the previous processing, and the photographing lens 102 is mounted this time. Therefore, in S602, the CPU 106 determines that the lens mounting flag is not set, and the process proceeds to S603.

  In S603, the CPU 106 determines whether or not the timer Tlock is greater than 0 and less than the timeout time T2. If this condition is satisfied, the process proceeds to S604. In step S <b> 604, the CPU 106 performs a return process for returning the various setting contents of the camera body 101 and the display contents of the display 109 to the backed up state. Therefore, the state stored in S705 in the switch pressing process in S406 of “(1) When the switch is pressed” stored in the memory 108 is restored. Thereafter, the process proceeds to S605 and S606. In S606, the CPU 106 resets the timer Tlock to “0” and returns to the flowchart of FIG.

In other words, from the state in which the photographic lens 102 is detached, the user accidentally attaches a photographic lens that does not have a communication function, that is, cannot be detected, and is attached to the camera body 101 via the operation unit 110 for a photographic lens that does not have a communication function. Assume that the settings have been made. Even in this case, if the user notices an error and attaches the photographing lens 102 having the communication function within the timeout time T2, the state of the camera body 101 is restored immediately before setting the photographing lens having no communication function. Therefore, since the setting for the photographing lens that does not have the communication function set halfway by the user is canceled, the user does not need to return the setting, and the convenience for the user can be improved. As described above, when the setting of the camera body 101 is completed, the timer Tlock is reset to 0 (S907), so the process does not proceed from S603 to S604 and is not restored. The state 101 is maintained in a state where the setting is completed.
Here, the timer Tlock starting from the release of the lock release unit 200 is used, but the timer Tlock is, for example, “when the (1) switch is pressed” or “(3” of the operation “F”. ) When the switch is released "may be the starting point. In this case, it is distinguished from the timer Tlock referred to by the timeout time T3.

The third is processing using a timeout time T3 (third predetermined time). Here, any operation is accepted after the time-out period T3 from the time when the lock release unit 200 is released. Here, the operation “H” will be described.
The process of “(1) When the switch is pressed” in the operation “H” will be described. In the flowchart of FIG. 4, in S401, the CPU 106 determines whether or not the timer Tlock is greater than the timeout time T3. Since the timer Tlock is larger than the timeout time T3 here, the process proceeds to S402. In S402, the CPU 106 resets the timer Tlock to “0”. Thereafter, the processing of S403, S404, S405, and S406 is the same as the processing of “when (1) switch is pressed” of operation “F”.

Next, the processing “(3) When the switch is released” in the operation “H” will be described. In the flowchart of FIG. 4, the processing of S401, S402, S403, and S404 is the same as the processing of “(1) When the switch is pressed” of the operation “H”. Next, the process proceeds to S405 and S407. In the switch release processing of S407, the process proceeds to S801, S802, S803, S804, S805, S806, and S807. In S807, the CPU 106 determines whether or not the timer Tlock is larger than 0 and smaller than the timeout time T3. Here, since the timer Tlock is 0, the process proceeds to S808. In S808, the CPU 106 timer Tlock is reset to “0”. In step S809, the CPU 106 resets the timer Tsw to “0”. Thereafter, the process proceeds to S901 and subsequent steps, and the CPU 106 performs a process according to the function of the switch.
Therefore, when the timer Tlock is larger than the timeout time T3, the timer Tlock is reset to “0” and does not advance from S807 to S810. It becomes processing. Therefore, an operation similar to the operation “A” and the operation “B” can be realized.

That is, when the time-out period T3 has elapsed since the unlocking unit 200 was released, the CPU 106 executes processing according to the operation performed by the user via the operation unit 110 even when the photographing lens 102 is removed. Therefore, it is possible to prevent a state where an operation is not accepted indefinitely, and to improve user convenience. As described above, when the setting of the camera body 101 is completed, the timer Tlock is reset to 0 (S907), so the process does not proceed from S603 to S604 and is not restored. The state 101 is maintained in a state where the setting is completed.
In S808, the CPU 106 resets the timer Tlock to “0”, but the condition is the same even if the measurement is actually continued beyond the timeout time T3. However, when the value of the timer Tlock overflows in the memory 108 and may return to less than the timeout time T3, it is preferable to reset the timer Tlock to “0”.

As described above, according to the present embodiment, when the photographing lens 102 is detached, the state of the imaging device is changed by an erroneous operation when the photographing lens is replaced by not performing an operation on the operation unit 110. Can be prevented. Therefore, the user can be prevented from being confused by unintentionally setting the camera body 101 or changing the display 109 to an unintended content. Further, it is possible to reduce time and effort for the user to return to the state before the erroneous operation.
Further, in this embodiment, when the photographing lens 102 is detached, the operation unit 110 is not uniformly operated, but only when a predetermined condition is satisfied, assuming that there is a high possibility of an erroneous operation. The operation on the operation unit 110 is not executed. In other words, even if the photographic lens 102 is detached, in the case of an intentional operation, processing corresponding to the operation is executed, so that convenience for the user can be improved.

  As mentioned above, although this invention was explained in full detail based on the suitable embodiment, this invention is not limited to embodiment mentioned above, Various forms of the range which does not deviate from the summary of this invention are also contained in this invention. . That is, the above-described embodiment is merely an embodiment of the present invention, and can be appropriately combined within the scope of the present invention.

Note that the control by the CPU 106 may be performed by a single piece of hardware, or the entire apparatus may be controlled by a plurality of pieces of hardware sharing the processing.
In the above-described embodiment, the case where the present invention is applied to a camera has been described as an example. However, the present invention is not limited to this case, and the present invention can be applied to any imaging device in which the photographing lens 102 can be attached and detached. That is, the present invention can be applied to portable terminals such as video cameras and smartphones.
