  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, configurations described in the following embodiments are merely examples, and the scope of the present invention is not limited by the configurations described in the embodiments.

[First embodiment]
FIG. 1 is a schematic external view of an imaging device 100 according to an embodiment of the present invention. The imaging device 100 of FIG. 1 includes a body 101 of a main body of the imaging device 100, a cylindrical adapter module 111 attached to a front surface of the body 101, and a cylindrical lens module 108 attached to a tip of the adapter module 111. Have. A first operation ring 109 and a second operation ring 110 are provided on the outer peripheral surface of the cylindrical lens module 108. The first operation ring 109 is provided near the tip of the lens module 108. The second operation ring 110 is provided closer to the base end of the lens module 108 than the first operation ring 109 is. The first operation ring 109 and the second operation ring 110 are rotatable along the outer peripheral direction of the lens module 108. A third operation ring 112 is provided on the outer peripheral surface of the adapter module 111 having a cylindrical shape. The third operation ring 112 is rotatable along the outer peripheral direction of the adapter module 111. In the imaging device 100 of FIG. 1, the lens module 108 and the adapter module 111 form a lens barrel 113 that is detachably attached to the imaging device 100. Note that the lens module 108 can be directly attached to the front surface of the body 101 of the imaging device 100 without interposing the adapter module 111. In this case, the lens barrel 113 is constituted only by the lens module 108. Further, the lens module 108 may include a first operation ring 109, a second operation ring 110, and a third operation ring 112 as operation members. The user can individually rotate the first operation ring 109, the second operation ring 110, and the third operation ring 112 to change the imaging setting corresponding to each. The first operation ring 109, the second operation ring 110, and the third operation ring 112 are, for example, a focus ring, a zoom ring, and an exposure ring. The focus ring is rotated to adjust the focus of the lens module 108. The zoom ring is rotated to adjust the angle of view of the lens module 108. The exposure ring is rotated to adjust the exposure value. The exposure value may be a discrete value. For this reason, the exposure ring may be provided so as to generate a click feeling for the operation so as to switch between a plurality of exposure values prepared in advance. For example, by providing irregularities between the exposure ring and the lens module 108, a click feeling for the operation can be obtained. On the other hand, it is preferable that the focus and the angle of view of the lens module 108 can be linearly adjusted with respect to a user operation. For this reason, the focus ring and the zoom ring may be provided so as to rotate smoothly with respect to the operation. In this case, the focus ring and the zoom ring do not give a click feeling to the operation.

  On an upper surface of a body 101 of the imaging apparatus 100, a release button 102 operated by a user for imaging is provided. The release button 102 is a two-stage switch according to the depth of pressing. When the release button 102 is pressed shallowly, a switch 209 for starting photometry and AF control is turned on. When the release button 102 is further depressed, the switch 210 for starting the imaging is turned on. A display device 104 of a touch panel type is provided on the back surface of the body 101 of the imaging device 100. On the upper side of the display device 104 of the touch panel type, an electronic viewfinder 103 that the user looks through is provided. The electronic viewfinder 103 and the display device 104 of a touch panel type display an image being captured in a live view display and display settings. The touch panel display device 104 detects an operation on an image to be displayed. On the left side of the display device 104 of the touch panel type, a display switching button 105, an image reproduction button 106, and an image enlargement button 107 are provided in a vertical arrangement. The display switching button 105 is a tact switch operated to switch the display of the electronic viewfinder 103 and the display device 104 of a touch panel type. The image reproduction button 106 is a tact switch operated to reproduce and display captured image data on the electronic viewfinder 103 and the touch panel display device 104. The image enlargement button 107 is a tact switch operated to change the display enlargement ratio of the display image being reproduced.

  FIG. 2 is a schematic block diagram of a control system of the imaging device 100 of FIG. 2 has a lens circuit 215, an adapter circuit 220, and a main body circuit 201. The lens circuit 215 includes a motor 217, a first detector 218, a second detector 219, and a lens processor 216 to which these are connected. The motor 217 focus-drives a plurality of lenses provided in the lens module 108. The first detector 218 detects rotation of the first operation ring 109. The second detector 219 detects rotation of the second operation ring 110. The lens processor 216 drives a plurality of lenses provided in the lens module 108 by the motor 217 in accordance with, for example, a rotation operation of the first operation ring 109 as a focus ring. The lens processor 216 outputs the detection value of the first detection unit 218 and the detection value of the second detection unit 219 to the main circuit 201. The adapter circuit 220 includes a third detection unit 222 that detects rotation of the third operation ring 112, an adapter processor 221 to which the third detection unit 222 is connected, and a communication path 223 between the lens processor 216 and the main circuit 201. The adapter processor 221 outputs the detection value of the third detection unit 222 to the main circuit 201.

  The main body circuit 201 includes two switches 209 and 210 constituting the release button 102, a display switching button 105, an image reproduction button 106, an image enlargement button 107, a mode button 214, and an imaging microprocessor 208 to which these are connected. Have. The imaging microprocessor 208 is a one-chip microcomputer having a CPU, a ROM, a flash memory, an EEPROM, a RAM, and an I / O port. The flash memory and the EEPROM are nonvolatile memories. RAM is volatile memory. A lens processor 216 and an adapter processor 221 are connected to an I / O port of the imaging microprocessor 208 through a communication path 223. The imaging microprocessor 208 communicates with the lens processor 216 and the adapter processor 221. The imaging microprocessor 208 holds various settings for imaging in a changeable manner, and controls the imaging apparatus 100 to an imaging state corresponding to the settings based on the settings. The imaging microprocessor 208 changes the value of the setting corresponding to the operation amount of the operation ring input from the lens processor 216 or the adapter processor 221, for example. For example, the focus setting value is changed and held in accordance with the amount of rotation of the first operation ring 109 as a focus ring. The setting value of the angle of view is changed and held according to the amount of rotation operation of the second operation ring 110 as a zoom ring. The exposure set value is changed and held in accordance with the amount of rotation of the third operation ring 112 as the exposure ring. These setting values may be recorded in a RAM or the like. Further, the imaging microprocessor 208 outputs operation information such as an operation amount of an operation ring input from the lens processor 216 or the adapter processor 221 to the main CPU 202 from the I / O port.

  The main circuit 201 includes a main CPU 202, a touch panel display device 104, a main RAM 204, a timer 212, an electronic viewfinder 103, a card type memory 205, an image sensor 203, and a system bus 213 connected to these. The imaging microprocessor 208 is connected to the system bus 213. The image sensor 203 is, for example, a CMOS sensor. The imaging element 203 receives the light collected through the lens module 108 and the adapter module 111 and captures an image of a subject. The image sensor 203 generates and outputs image data of a captured image. Timer 212 measures time or time. The timer 212 measures, for example, the duration of the operation of the first operation ring 109, the duration of the operation of the second operation ring 110, and the duration of the operation of the third operation ring 112. The timer 212 may be incorporated in a one-chip microcomputer as the main CPU 202. The main RAM 204 is a volatile random access memory, and is a work memory of the main CPU 202. The card type memory 205 is a card type non-volatile memory. The card type memory 205 records captured image data and the like. The card type memory 205 may store a program executed by the main CPU 202. The program may be stored in a non-volatile memory (not shown) of the main CPU 202. The main CPU 202 is, for example, a one-chip microcomputer. The main CPU 202 expands a program recorded in the internal memory or the card type memory 205 or the like into the main RAM 204 and executes the program. Thus, a control unit that controls the entire operation of the imaging device 100 is realized. The main CPU 202 acquires operation information of the first operation ring 109, the second operation ring 110, the third operation ring 112, the touch panel display device 104, and various switches and buttons via the system bus 213. The main CPU 202 allows the imaging microprocessor 208 to change the imaging setting and controls the operation of the imaging device 100 using the acquired operation information. For example, when capturing an image, the main CPU 202 displays the image being captured on the display device 104 of the touch panel type or the electronic viewfinder 103. Further, the main CPU 202 stores the captured image data in the card type memory 205.

  FIG. 3 is a flowchart showing a flow of a main loop process executed by the CPU of FIG. 2 at the time of imaging. The flowchart of FIG. 3 is realized by expanding a program stored in the nonvolatile memory of the main RAM 204 into the main RAM 204 and executing the program by the main CPU 202. In step S301, the main CPU 202 starts a main loop process after a startup process when the power of the imaging apparatus 100 is turned on. FIG. 3 does not show processing unrelated to the present invention. In addition, description of routine processing such as task processing, event waiting, and event type determination processing in a real-time operating system (RTOS) will be omitted. In step S302, the main CPU 202 uses the imaging microprocessor 208 to communicate with the lens processor 216 and the adapter processor 221 provided in the lens barrel unit 113. The main CPU 202 acquires configuration information about the lens barrel 113 mounted on the imaging device 100. The main CPU 202 acquires, for example, information on the first operation ring 109, the second operation ring 110, and the third operation ring 112 as information on the operation rings provided on the lens barrel 113. In step S303, the main CPU 202 saves the information obtained by the lens communication in the lens communication repository 303. The lens communication repository 303 may be stored, for example, in the main RAM 204. The lens information stored in the lens communication repository 303 will be described later with reference to FIG. In step S304, the main CPU 202 performs UI control using the detection results of the switches and buttons of the imaging apparatus 100 and information from the lens communication repository 303. In the UI control, the main CPU 202 displays various setting values for imaging on the touch panel display device 104 or the electronic viewfinder 103 as a user interface. The main CPU 202 selects and changes a new set value based on an operation on the touch panel display device 104 and switches and buttons. In step S305, the main CPU 202 executes an AE process. In the AE process, the main CPU 202 performs an exposure calculation process according to a photometry condition and an exposure mode set by a user in the UI control. In step S306, the main CPU 202 executes an AF process. In the AF process, the main CPU 202 performs a focus adjustment process according to a distance measurement condition and an AF mode set by a user in the UI control. In step S307, the main CPU 202 executes an imaging process. In the imaging process, the main CPU 202 acquires image data from the imaging element 203 according to release conditions such as continuous shooting at the timing when the user presses the release button 102. In step S308, the main CPU 202 ends the main loop processing of FIG. The main CPU 202 returns the process to step S301. Thereby, the imaging device 100 can repeatedly capture an image based on the setting of the user.

  FIG. 4 is a flowchart showing the flow of the operation detection process executed by the CPU in step S304 in FIG. 4 is realized by expanding a program stored in the nonvolatile memory of the main RAM 204 into the main RAM 204 and executing the program by the main CPU 202. In step S401, the main CPU 202 starts the process of step S304 in FIG. In step S402, the main CPU 202 detects a state change due to an operation on various switches and buttons of the imaging device 100. If there is a switch or button whose state has changed, the main CPU 202 executes a process corresponding to the state change. For example, when the state of the switch 209 of the release button 102 is changed by the operation, the main CPU 202 generates an event for executing the AE process of step S305, which is the next process in FIG. In step S403, the main CPU 202 detects an operation on the lens barrel 113 based on the information detected in step S303. The main CPU 202 detects an operation of the first operation ring 109, the second operation ring 110, and the third operation ring 112, for example. In step S404, the main CPU 202 detects an operation on parts other than the lens barrel unit 113, for example, an operation on an accessory of the imaging apparatus 100. Here, the operation on the accessory includes, for example, a release operation using a wireless remote controller or a wireless strobe. In step S405, the main CPU 202 ends the operation detection processing of FIG. The main CPU 202 returns the process to the calling source in FIG.

  FIG. 5 is a flowchart showing the flow of the lens operation process executed by the CPU in step S403 in FIG. The flowchart in FIG. 5 is realized by expanding a program stored in the nonvolatile memory of the main RAM 204 into the main RAM 204 and executing the program by the main CPU 202. In step S501, the main CPU 202 starts the process of step S403 in FIG. In step S502, the main CPU 202 acquires information on the configuration of the lens barrel 113 required for the subsequent processing from the lens communication repository 303. The main CPU 202 sets the number of operation rings provided on the lens module 108 and the adapter module 111 constituting the lens barrel 113 to the number of executions of the next loop. In step S503, the main CPU 202 starts a loop process repeated for the number of operation rings. In step S504, the main CPU 202 calls a subroutine of an operation ring operation process of FIG. 6 described later. The main CPU 202 switches and designates a main operation ring to be processed, and calls a subroutine of the operation ring operation process in FIG. Thereby, in the operation ring operation processing of FIG. 6 that is repeatedly called with the number of operation rings, it is possible to grasp which operation ring is the main target of the processing. In step S505, the main CPU 202 ends the loop processing repeated for the number of operation rings. In step S506, the main CPU 202 changes the setting value of the imaging setting corresponding to the operation ring or executes control corresponding to the operation ring based on the processing result of step S504 repeated with the number of operation rings. . In step S507, the main CPU 202 ends the lens operation processing in FIG. The main CPU 202 returns the process to the calling source in FIG.

  FIG. 6 is a flowchart showing the flow of the operation ring operation process in the first embodiment, which is executed by the CPU in step S504 of FIG. The flowchart of FIG. 6 is realized by expanding a program stored in the nonvolatile memory of the main RAM 204 into the main RAM 204 and executing the program by the main CPU 202. In step S601, the main CPU 202 starts the process of step S504 in FIG. In step S602, the main CPU 202 acquires lens information from the lens communication repository 303. In step S603, the main CPU 202 acquires the number and arrangement of the operation rings of the lens barrel 113 from the information in the lens communication repository 303. In step S604, the main CPU 202 acquires a determination threshold value for determining the validity of the operation of the operation ring. In step S605, the main CPU 202 obtains the operation amount of the operation ring based on the information in the lens communication repository 303. Here, the operation ring refers to the operation ring designated as the main target in step S504. In the present embodiment, there are three operation rings. In this case, the main CPU 202 uses the first operation ring 109 as the main operation ring, the second operation ring 110 as the main operation ring, and the third operation ring 112 as the main operation ring in the three calls in FIG. become. For example, in the three calls in FIG. 6, the main CPU 202 may process the lens barrel 113 from the operation ring on the base end side on the body 101 side in order. In the processing in the order from the base end, the main CPU 202 first sets the third operation ring 112 as the main operation ring, then sets the second operation ring 110 as the main operation ring, and finally sets the first operation ring 109 as the main operation ring. A ring. Further, the main CPU 202 may execute a process of setting each operation ring as a main operation ring based on detection of the start of operation of each operation ring. The main CPU 202 may execute the flowchart of FIG. 6 for each of the operation rings when the main CPU 202 detects that the operation is started.

  In step S606, the main CPU 202 obtains the operation amount of another operation ring operated within a predetermined time in the processing of step S608 described later based on the information in the lens communication repository 303. In step S607, the main CPU 202 acquires the positional relationship between the operation ring and another operation ring from the lens communication repository 303. For example, a case where a lens A of FIG. 7 described later is mounted will be described. In this case, when the first operation ring 109 is the main operation ring and the other operation ring is the second operation ring 110, the main CPU 202 transmits information indicating that the arrangement position of the first operation ring 109 is 120 mm from the lens mount surface. Can be obtained. Further, the main CPU 202 can acquire information that the arrangement position of the second operation ring 110 is 80 mm. Accordingly, the main CPU 202 can acquire information that the second operation ring 110 is provided at a position distant from the first operation ring 109 by −40 mm (= 80 mm−120 mm). Similarly, when the third operation ring 112 is another operation ring, the main CPU 202 transmits, to the first operation ring 109, information indicating that the third operation ring 112 is provided at a position distant by -60 mm. Can be obtained. When the second operation ring 110 is the main operation ring and the third operation ring 112 is another operation ring, the main CPU 202 determines that the third operation ring 112 is provided -20 mm before the second operation ring 110. Information can be obtained. In step S608, the main CPU 202 acquires and compares the operation times of these operation rings from the lens communication repository 303 information, and operates the other operation rings immediately before the operation time of this operation ring is within a predetermined time. Is determined. If another operation ring has not been operated immediately before the operation time of this operation ring is within the predetermined time, the main CPU 202 advances the process to step S609. When another operation ring is operated immediately before the operation time of the operation ring becomes within a predetermined time, the main CPU 202 advances the process to step S612.

  In step S609, the main CPU 202 determines whether another operation link is located immediately before this operation ring. The main CPU 202 determines whether or not the operation ring is located immediately before based on the information on the arrangement position of the operation ring acquired from the lens communication repository 303. If another operation link is not located immediately before this operation ring, the main CPU 202 advances the process to step S617. If another operation link is located immediately before this operation ring, the main CPU 202 advances the process to step S610. In step S610, the main CPU 202 determines whether or not another operation ring that is determined to be in the immediate front has a click feeling. If another operation ring causes a click feeling, the main CPU 202 advances the process to step S617. If another operation ring does not cause a click feeling, the main CPU 202 advances the process to step S611. In step S611, the main CPU 202 increases the determination threshold for determining the validity of the operation of another operation ring that is located immediately before and does not generate a click feeling so as to be larger than the normal value. The main CPU 202 adds a value corresponding to the distance between the rings to, for example, the “basic validity determination threshold” of the “lens static information” in FIG. The main CPU 202 adds a larger value as the distance between the rings is shorter. When the determination threshold increases, it becomes difficult for the main CPU 202 to determine that the operation is valid. Accordingly, when there is no other operation ring operated within the predetermined time before the operation ring on which the operation was performed, the main CPU 202 determines at least one of the operation rings other than the operation ring related to the operation. The judgment threshold can be changed to be larger than the normal value. The main CPU 202 can change the judgment threshold value of another operation ring provided closer to the base end side of the lens barrel 113 than the operation ring related to the operation to a value larger than the normal value. The main CPU 202 changes the determination threshold to a value larger than the normal value when another operation ring provided on the base end side of the lens barrel 113 with respect to the operation ring related to the operation does not cause a click feeling to the operation. be able to. The main CPU 202 can change, for example, a focus ring determination threshold and a zoom ring determination threshold that do not cause a click feeling to the operation between a normal value and a value larger than the normal value. Further, the main CPU 202 returns the judgment threshold value of the operation ring to the normal value. The main CPU 202 stores these changed validity operation determination thresholds in the “variable effectiveness determination threshold” setting of “information that can be changed from the imaging device 100” of each operation ring.

  In step S612, the main CPU 202 determines whether or not another operation ring is immediately before this operation ring. If this operation ring is the first operation ring 109, the main CPU 202 determines that the adjacent second operation ring 110, which is 40 mm away from the front, is not the third operation ring 112, which is 60 mm away from the front. If another operation ring is immediately before this operation ring, the main CPU 202 advances the process to step S613. If the other operation ring is not immediately before this operation ring, the main CPU 202 advances the process to step S615. In step S613, the main CPU 202 determines whether the operation of another operation ring has been continued for a predetermined time or more. The main CPU 202 determines, for example, whether or not the operation time of another operation ring of the lens communication repository 303 is continuously recorded within a predetermined time and whether or not the operation time is continuous for a predetermined time or more. I do. If the operation of another operation ring has been continued for a predetermined time or longer, the main CPU 202 advances the process to step S617. If the operation of another operation ring has not been continued for a predetermined time or longer, the main CPU 202 advances the process to step S614. In step S614, the main CPU 202 increases the determination threshold for determining the validity of the operation of another operation ring so as to be larger than the normal value. When there is another operation ring of the immediately preceding operation operated within a predetermined time before the operation ring where the operation was performed, the main CPU 202 can change the determination threshold value of the operation ring of the immediately preceding operation to a value larger than the normal value. . When the operation ring of the immediately preceding operation is provided closer to the base end side of the lens barrel unit 113 than the operation ring related to the operation, the main CPU 202 sets the judgment threshold value of the immediately preceding operation ring to a normal value. Can be changed significantly. When the operation ring of the immediately preceding operation is not continuously operated, the main CPU 202 can change the determination threshold value of the operation ring of the immediately preceding operation to a value larger than the normal value.

  In step S615, the main CPU 202 determines whether the operation of the operation ring has been continued for a predetermined time or more. If the operation of the operation ring has been continued for a predetermined time or longer, the main CPU 202 advances the process to step S617. If the operation of the operation ring has not been continued for a predetermined time or longer, the main CPU 202 advances the process to step S616. In step S616, the main CPU 202 sets the determination threshold for determining the validity of the operation of the operation ring to be higher than the normal value. If there is another operation ring of the immediately preceding operation that has been operated within a predetermined time before the operation ring where the operation has been performed, the main CPU 202 may change the determination threshold value of the operation ring that has been operated to be larger than the normal value. it can. The main CPU 202 sets the determination threshold value of the operation ring on which the operation has been performed when the operation ring on which the operation has been started is provided closer to the base end side of the lens barrel 113 than the operation ring of the immediately preceding operation. It can be changed to a value larger than the normal value. When the operation ring whose operation has been started is not continuously operated, the main CPU 202 can change the determination threshold value of the operation ring of the immediately preceding operation to a value larger than the normal value.

  In step S617, the main CPU 202 determines whether the operation amount of another operation ring is equal to or larger than a determination threshold. If the operation amount of the other operation ring is equal to or larger than the determination threshold, the main CPU 202 advances the processing to step S618. In step S618, the main CPU 202 as a permission unit records, in the lens communication repository 303, information for permitting a setting change based on an operation of another operation ring. In step S619, the main CPU 202 returns the determination threshold value of the other operation ring to the basic effectiveness determination threshold value as a normal value. After permitting the change of the imaging setting, the main CPU 202 as a changing unit can return to the normal value when the determination threshold value corresponding to the operation ring related to the permission has been changed to be larger than the normal value. When the operation amounts of the other operation rings are not equal to or larger than the determination threshold, the main CPU 202 advances the processing to step S620. In step S620, the main CPU 202 as a prohibition unit records information for prohibiting a setting change based on an operation of another operation ring in the lens communication repository 303. By the above processing, the main CPU 202 as a changing unit, when any one of the plurality of operation rings 109, 110, and 112 is operated, determines the validity of the operation according to the operation. A plurality of judgment thresholds can be changed. For example, the main CPU 202 as a change unit changes the determination threshold value of the operation ring related to the operation to return to the normal value, and changes at least one determination threshold value of the other operation rings to a value larger than the normal value. be able to.

  In step S621, the main CPU 202 determines whether the operation amount of the operation ring is equal to or greater than a determination threshold. When the operation amount of the operation ring is equal to or larger than the determination threshold, the main CPU 202 advances the processing to step S622. In step S622, the main CPU 202 as a permission unit records information for permitting the setting change based on the operation of the operation ring in the lens communication repository 303. In step S623, the main CPU 202 returns the threshold value for determining the operation ring to the threshold value for determining the basic effectiveness, which is a normal value. After permitting the change of the imaging setting, the main CPU 202 as a changing unit can return to the normal value when the determination threshold value corresponding to the operation ring related to the permission has been changed to be larger than the normal value.

  If the operation amount of the operation ring is not equal to or larger than the determination threshold, the main CPU 202 advances the processing to step S624. In step S624, the main CPU 202 as the prohibition unit records information for prohibiting the setting change based on the operation of the operation ring in the lens communication repository 303. In step S625, the main CPU 202 ends the operation ring operation process of FIG. The main CPU 202 returns the processing to the calling source in FIG. In step S506 of FIG. 5, the main CPU 202 as operation determination means determines the validity of the operation of each operation ring based on a comparison between the operation amount of each operation ring and a determination threshold. Then, the main CPU 202 changes the set value of the imaging setting or executes control corresponding to the operation ring according to the operation amount equal to or larger than the determination threshold.

  FIG. 7 is an explanatory diagram of an example of the data structure of the lens communication repository 303 for managing the operation of the operation ring. The main CPU 202 centrally manages information on the lens barrel 113 in the lens communication repository 303. The lens communication repository 303 in FIG. 7 may be recorded in, for example, a nonvolatile memory of the main CPU 202 or a card-type memory 205. When the lens barrel unit 113 is mounted on the imaging device 100, the main CPU 202 transmits and receives various information through communication between the imaging device 100 and the lens, and updates information in the lens communication repository 303 as necessary. FIG. 7 shows only the information on the operation ring among the information in the lens communication repository 303. The lens communication repository 303 stores various other information that can be used for AE processing, AF processing, image processing, and the like. FIG. 7 illustrates information about two lens modules 108 of the lens A and the lens B. Here, the lens A will be described as an example. The lens A has three operation rings. In this case, the information on the lens module 108 of the lens A includes information on rings 1 to 3. The information on each ring is composed of lens static information and lens dynamic information. The lens static information includes an arrangement position, a click presence / absence, and a validity determination threshold as a normal value. The arrangement position is information on the distance from the lens mount of the imaging apparatus 100 to which the lens barrel 113 is attached. The click presence / absence is information on whether the operation ring is to be rotated smoothly when rotated, or to be rotated with a ticking and click feeling. The validity determination threshold value is an initial value of a threshold value for determining whether or not the operation amount detected by the detection unit of the operation ring may be reflected in the setting change of the imaging device 100. This initial value is a normal value. The effectiveness determination threshold may be different depending on the size of the operation ring, the ease of rotation, and the presence or absence of a click. The lens dynamic information includes an operation time and an operation amount of the operation ring, and a setting change permission prohibition flag. In the lens dynamic information, a plurality of sets of operation times and operation amounts are arranged in chronological order. The operation time of the operation ring may be the operation time when the rotation of the operation ring is detected. When the lens module 108 detects the operation time, the time of the lens module 108 may be synchronized with the time of the timer 212 of the imaging device 100. The operation amount of the operation ring may be a count value of a rotation pulse generated by rotation of the operation ring. If there is a limit to the number of sets of operation times and operation amounts that can be recorded in the lens dynamic information, the oldest information of the lens dynamic information may be updated with new information like a ring buffer. The setting change permission prohibition flag is a flag indicating permission or prohibition of the setting change by operating the operation ring. Then, the main CPU 202 updates, for example, the validity determination threshold, the allocation function, and the setting change permission prohibition flag. The main CPU 202 updates the value of the threshold for determining the validity of each operation ring between the normal value and a value larger than the normal value by the update process of FIG. The main CPU 202 may update an imaging setting changed by operating the operation ring as an assignment function. The main CPU 202 updates the value of the setting change permission prohibition flag of each operation ring between permission and prohibition according to the threshold determination in FIG. Then, the main CPU 202 can control whether or not the setting can be changed by, for example, updating in step S504 in FIG. 5 and reading out in step S506.

  FIG. 8 is an explanatory diagram of an operation state of a plurality of operation rings 109, 110, and 112 provided side by side on the lens barrel 113. The lens barrel 113 of the imaging apparatus 100 in FIG. 8 includes a first operation ring 109, a second operation ring 110, and a third operation ring 112 in this order from the distal end side. In FIG. 8A, the user's hand 804 rotates the first operation ring 109. In this case, the base of the thumb of the user's hand 804 may touch the second operation ring 110 located on the near side. If the first operation ring 109 is rotated in this state, the rotation of the second operation ring 110 that is not intended to be operated is detected. Note that the user's hand 804 does not cover the third operation ring 112 which is located far away from the first operation ring 109 toward the base end. Even if the first operation ring 109 is rotated, the third operation ring 112 does not rotate unintentionally. In FIG. 8B, the user's hand 804 rotates the second operation ring 110. In this case, the base of the thumb of the user's hand 804 may touch the third operation ring 112 located on the near side. If the second operation ring 110 is rotated in this state, the rotation of the third operation ring 112 that is not intended to be operated is detected. However, when the third operation ring 112 is a type of ring having a click feeling, the third operation ring 112 is difficult to rotate even if the hand 804 is put on as shown in FIG. Note that the user's hand 804 does not cover the first operation ring 109 located on the distal end side of the second operation ring 110. Even if the second operation ring 110 is rotated, the first operation ring 109 does not rotate unintentionally. In FIG. 8C, the user's hand 804 rotates the third operation ring 112. In this case, the user's hand 804 does not cover the first operation ring 109 and the second operation ring 110 located on the distal end side of the third operation ring 112. Even if the third operation ring 112 is rotated, the first operation ring 109 or the second operation ring 110 does not rotate unintentionally. The above operation example will be described in detail in comparison with FIG. The process of FIG. 6 is called from the loop process of FIG. It should be noted that the following description focuses on the points at which the operation has changed during repeated calls. 8A, when the user starts operating the first operation ring 109 and does not touch another operation ring, the process of the main CPU 202 proceeds to N in a branch of step S608, and steps S609 and S610. And branch to Y. The main CPU 202 executes the process of step S611. Further, since the other operation rings are not erroneously operated, the process of the main CPU 202 branches to N in step S617. The main CPU 202 prohibits the setting change based on the operation of another operation ring in step S620. In addition, since the first operation ring 109 is the main operation ring, the main CPU 202 changes the setting based on the operation of the first operation ring 109 when the operation of the first operation ring 109 is equal to or more than the normal determination threshold. Allow

  When the base of the thumb touches the second operation ring 110 while operating the first operation ring 109 as shown in FIG. 8A, the process of the main CPU 202 proceeds to Y in a branch of step S608. Since the operation amount of the second operation ring 110 is present and the position is immediately before the second operation ring 110, the process of the main CPU 202 branches to Y in step S612. At the timing when the operation of the second operation ring 110 starts, the process of the main CPU 202 branches to N in step S613, and the determination threshold value of the second operation ring 110 is increased. Since the determination threshold is set higher for the operation amount caused by the erroneous operation, the process of the main CPU 202 branches to N in step S617, and prohibits the setting change based on the operation of the second operation ring 110 in step S620. It should be noted that the operation of the second operation ring 110 does not continue for a predetermined time or more while the first operation ring 109 is being operated during an erroneous operation. An erroneous operation of the second operation ring 110 is detected as a discrete operation amount. Therefore, the case where the process of the main CPU 202 branches to Y in step S613 is a case where the first operation ring 109 and the second operation ring 110 are intentionally rotated simultaneously.

  The user may start operating the second operation ring 110 following the operation of the first operation ring 109. In this case, at the timing when the main CPU 202 performs the processing from step S601 after the operation of the second operation ring 110 is started, a predetermined time may not have elapsed from the last operation by the first operation ring 109. . Then, the process of the main CPU 202 branches to Y in step S608, branches to N in step S612, and branches to N in step S615. In this case, the judgment threshold value of the second operation ring 110 becomes high. However, the user continuously operates the second operation ring 110 with the intention of changing the setting. On the other hand, since the first operation ring 109 is located on the front end side of the lens, there is no possibility of erroneous operation. Therefore, after the continuation of the operation for a predetermined time, the processing of the main CPU 202 branches to Y in step S615, and branches to Y in step S621. In this case, the determination threshold value of the second operation ring 110 returns to the normal value. Alternatively, after the elapse of a predetermined time or more, the process of the main CPU 202 branches to N in step S608, and branches to Y in step S621 by an operation with a high threshold or more. In this case, the determination threshold value of the second operation ring 110 returns to the normal value. Therefore, after the elapse of the predetermined time, the operation of the second operation ring 110 is determined to be valid based on the determination threshold of the normal value, and is used for setting change.

  The user may start operating the first operation ring 109 following the operation of the second operation ring 110. Immediately after shifting to the operation of the first operation ring 109, the process of the main CPU 202 branches to Y in step S608 and further to Y in step S612 because the second operation ring 110 has been operated. Unlike when the second operation ring 110 was operated intentionally, the operation of the first operation ring 109 is an unintentional touch operation, and the operation of the second operation ring 110 is less than a predetermined time. May occur. In this case, the process of the main CPU 202 branches to N in step S613, and the determination threshold value of the second operation ring 110 is set high in step S614.

  Here, the case where an erroneous operation occurs by touching the third operation ring 112 when operating the first operation ring 109 or the second operation ring 110 is basically the same as the above-described case, and the description thereof will be omitted. . The third operation ring 112, which is another operation ring, produces a click feeling. In this case, the process of the main CPU 202 branches to N in step S610. For this reason, the determination threshold value of the third operation ring 112 does not change to a high value at the time when the erroneous operation of the third operation ring 112 is not detected just by starting the operation of the second operation ring 110.

  As described above, in the present embodiment, when an operation is performed on a plurality of operation rings 109, 110, and 112 provided side by side in the lens barrel unit 113, a plurality of determination thresholds corresponding to each operation ring are used. Determine the validity of the operation. Then, the change of the imaging setting based on the operation amount of the operation ring for which the operation is determined to be valid is permitted. Further, the change of the imaging setting based on the operation amount of the operation ring for which the operation is determined to be invalid is prohibited. In addition, when any one of the operation rings 109, 110, 112 is operated after a predetermined time, the validity of each operation of the operation rings 109, 110, 112 is determined. To change a plurality of judgment thresholds for For example, the determination threshold of the operation ring related to the operation is changed to return to the normal value, and at least one determination threshold of the other operation rings is changed to be larger than the normal value. Therefore, even when an operation ring other than the operation ring operated by the user with the intention of the operation is operated unintentionally, the operation of the other unintended operation ring can be determined to be invalid. That is, it is possible to prohibit the change of the imaging setting due to the invalid operation. Further, after the change of the imaging setting is permitted by the main CPU 202 as the permission means, if the determination threshold value corresponding to the operation ring relating to the permission is changed to a value larger than the normal value, the value is returned to the normal value. Therefore, the user intentionally operates one of the plurality of operation rings 109, 110, and 112 provided in order from the distal end side of the lens barrel 113. At this time, even if the other operation ring is operated unintentionally, the present embodiment can prohibit the imaging setting from being changed by the unintended operation. In addition, when the user intentionally operates the plurality of operation rings 109, 110, and 112, the change of the imaging setting can be permitted for each intentional operation by using the determination threshold of the normal value.

  In the present embodiment, when there is no other operation ring of the immediately preceding operation operated within a predetermined time before the operation ring where the operation was performed, at least one of the operation rings other than the operation ring related to the operation is operated. One of the judgment thresholds is changed to be larger than the normal value. Therefore, even if another operation ring is erroneously operated when the operation ring related to the operation is operated, the imaging setting can be hardly changed by the determination threshold value that is changed to be larger than the normal value. In particular, in the present embodiment, since the operation ring related to the operation is provided closer to the base end side of the lens barrel 113, the judgment threshold value for the other operation ring that is easily operated by mistake is increased. In addition, it is possible to suppress a change in the imaging setting due to an erroneous operation. In the present embodiment, the determination threshold value is set to the normal value when another operation ring provided on the base end side of the lens barrel 113 with respect to the operation ring related to the operation does not cause a click feeling to the operation. Make a larger change. Thus, in the present embodiment, it is possible to suppress a change in the imaging setting of another operation ring that is easily operated due to an erroneous operation. In the present embodiment, when there is another operation ring of the immediately preceding operation that has been operated within a predetermined time before the operation ring where the operation has been performed, the determination threshold value of the operation ring of the immediately preceding operation is changed to be larger than the normal value. For example, when the operation ring of the immediately preceding operation is provided closer to the base end side of the lens barrel 113 than the operation ring relating to the operation, the determination threshold value of the immediately preceding operation ring is set to be larger than the normal value. change. Further, in the present embodiment, when the operation ring of the immediately preceding operation is provided closer to the base end side of the lens barrel 113 than the operation ring related to the operation, the threshold value for determining the operation ring of the immediately preceding operation is Change to a value larger than the normal value. Therefore, in the present embodiment, even when another operation ring is erroneously operated at the time of operating the operation ring related to the operation, the imaging setting is hardly changed by the determination threshold value changed to be larger than the normal value. it can. In the present embodiment, when there is another operation ring of the immediately preceding operation that has been operated within a predetermined time before the operation ring where the operation has been performed, the determination threshold value of the operation ring that has been operated is changed to be larger than the normal value. Therefore, even if the operation ring is erroneously operated at the time of operating the operation ring of another immediately preceding operation, it is possible to make it difficult for the imaging setting to be changed by the determination threshold value changed to be larger than the normal value. In particular, in the present embodiment, when the operation ring for which the operation has been started is provided immediately near the base end side of the operation ring of the immediately preceding operation, the determination threshold value of the operation ring is changed to be larger than the normal value. I do. Thus, in the present embodiment, it is possible to suppress a change in the imaging setting due to an erroneous operation. Further, in the present embodiment, when the operation ring whose operation has been started is not continuously operated, the determination threshold value of the operation ring of the immediately preceding operation is changed to be larger than the normal value. Thus, in the present embodiment, it is possible to suppress a change in the imaging setting due to an erroneous operation. In the present embodiment, the plurality of operation rings 109, 110, and 112 include an exposure ring, a focus ring, and a zoom ring. The exposure ring gives a click feeling to the operation, and the focus ring and the zoom ring do not give a click feeling to the operation. In this case, the focus ring determination threshold and the zoom ring determination threshold are changed between a normal value and a value larger than the normal value. Accordingly, it is possible to prevent the imaging setting from being changed by an unintended erroneous operation of the focus ring and the zoom ring that does not cause a click feeling to the operation.

[Second embodiment]
Next, an imaging device 100 according to a second embodiment of the present invention will be described. In the present embodiment, the operation ring operation processing for the plurality of operation rings 109, 110, and 112 is different. In the following description, differences from the imaging device 100 of the first embodiment will be mainly described. In the present embodiment, the first operation ring 109 on the distal end side of the lens barrel 113 is an exposure ring, the second operation ring 110 is a zoom ring, and the third operation ring 112 is a focus ring.

  FIG. 9 is a flowchart illustrating the flow of the operation ring operation process according to the second embodiment. The flowchart of FIG. 9 is realized by expanding a program stored in the nonvolatile memory of the main RAM 204 into the main RAM 204 and executing the program by the main CPU 202. When called from step S504 in FIG. 5, the main CPU 202 executes the operation ring operation process in FIG. 9 instead of FIG. The main CPU 202 repeats the operation ring operation process of FIG. 9 three times by calling three times, which is the number of operation rings, as in the case of FIG. Further, the main CPU 202 may perform the processing in order from the operation ring on the base end side on the body 101 side of the lens barrel 113, or may perform the processing based on the detection of the operation start of each operation ring. Hereinafter, the operation ring to be processed at the time of calling will be described as this operation ring. For example, the main CPU 202 first calls the operation ring operation process of FIG. 9 using the third operation ring 112 that is the focus ring as the main operation ring. Next, the main CPU 202 calls the operation ring operation process of FIG. 9 using the second operation ring 110, which is a zoom ring, as the main operation ring. Finally, the main CPU 202 uses the first operation ring 109, which is the exposure ring, as the main operation ring and calls the operation ring operation process of FIG. The processing up to calling the operation ring operation processing in FIG. 9 is the same as in the first embodiment, and a description thereof will be omitted.

  In step S901, the main CPU 202 starts the ring operation processing of the present embodiment. In step S902, the main CPU 202 acquires the function and operation amount of the operation ring from the lens communication repository 303. In step S904, the main CPU 202 determines whether the operation ring is an exposure ring. If the operation ring is an exposure ring, in step S907, the main CPU 202 sets an exposure ring determination threshold to an operation effectiveness threshold of the operation ring. After that, in step S909, the main CPU 202 sets the threshold for determining the effectiveness of the operation of the focus ring to a large value higher than the normal value. If the operation ring is not the exposure ring, the main CPU 202 advances the processing to step S905. In step S905, the main CPU 202 determines whether the operation ring is a zoom ring. If the operation ring is a zoom ring, in step S908, the main CPU 202 sets a threshold value for determining the effectiveness of operation of the zoom ring to an operation effectiveness threshold value of the operation ring. After that, in step S909, the main CPU 202 sets the threshold for determining the effectiveness of the operation of the focus ring to a large value higher than the normal value. If the operation ring is not a zoom ring, the main CPU 202 sets the threshold value for determining the effectiveness of the operation of the focus ring to the operation effectiveness threshold value of the operation ring in step S906. As described above, the main CPU 202 as a changing unit changes the determination threshold value of the operation ring related to the operation to return to the normal value, and is provided on the base end side of the lens barrel 113 with respect to the operation ring related to the operation. The focus ring determination threshold is changed to be larger than the normal value.

  When the above-described update processing of the determination threshold is completed, the main CPU 202 determines in step S910 whether or not the operation amount of the operation ring is equal to or more than the determination threshold of the validity of the operation ring. If the operation amount of the operation ring is not equal to or larger than the determination threshold, the main CPU 202 prohibits the setting change by the operation of the operation ring in step S911. The main CPU 202 records in the lens communication repository 303 that the setting change by operating the operation ring is prohibited. When the operation amount of the operation ring is equal to or larger than the determination threshold, the main CPU 202 permits the setting change by operating the operation ring in step S912. The main CPU 202 records in the lens communication repository 303 that the setting change by operating the operation ring is permitted. After that, in step S913, the main CPU 202 checks whether only the third operation ring 112, which is the focus ring, is permitted to change the setting, and sets the threshold for determining the effectiveness of the operation of the focus ring to the normal operation validity threshold. Change to threshold. This is, for example, a change process on the assumption that the number of calls before this time is a process in which the operation ring is called as the operation ring and the zoom ring, and both of the operation amounts are equal to or smaller than the determination threshold. In this case, the main CPU 202 needs to permit setting change of the focus ring. Therefore, in step S913, the main CPU 202 returns the threshold value for determining the validity of the operation of the third operation ring 112, which is the focus ring, to the normal value.

  In step S914, the main CPU 202 ends the operation ring operation process of FIG. The main CPU 202 returns the processing to the calling source in FIG. In step S506 of FIG. 5, the main CPU 202 as operation determination means determines the validity of the operation of each operation ring based on a comparison between the operation amount of each operation ring and a determination threshold. Then, the main CPU 202 changes the set value of the imaging setting or executes control corresponding to the operation ring according to the operation amount equal to or larger than the determination threshold.

  As described above, in the present embodiment, when an operation is performed on a plurality of operation rings 109, 110, and 112 provided side by side in the lens barrel unit 113, a plurality of determination thresholds corresponding to each operation ring are used. Determine the validity of the operation. Then, the change of the imaging setting by the operation of the operation ring determined to be valid is permitted. Further, the change of the imaging setting by the operation of the operation ring determined to be invalid is prohibited. In addition, when any one of the operation rings 109, 110, 112 is operated, a plurality of determinations for determining the validity of each operation of the plurality of operation rings 109, 110, 112 are performed. Change the threshold. For example, the determination threshold value of the operation ring related to the operation is changed back to the normal value, and the determination threshold value of at least one operation ring provided on the base end side of the lens barrel 113 with respect to the operation ring related to the operation is set to the normal value. Change it larger than the value. Therefore, even when an operation ring other than the operation ring operated by the user with the intention of the operation is operated unintentionally, the operation of the other unintended operation ring can be determined to be invalid. That is, it is possible to prohibit the change of the imaging setting due to the invalid operation. Therefore, for example, the user intentionally operates one of the plurality of operation rings 109, 110, and 112 provided in order from the distal end side of the lens barrel 113. At this time, even if the other operation ring is operated unintentionally, in the present embodiment, it is possible to prohibit the imaging setting from being changed by the unintended operation. In addition, when the user intentionally operates the plurality of operation rings 109, 110, and 112, the change of the imaging setting can be permitted for each intentional operation by using the determination threshold of the normal value.
