[0003] [Patent Document 1] JP 2019-020554 A Summary of the Invention [Problem to be solved by the invention]

[0004] The operating device includes an operating device (endless operating device) that does not have a mechanical end in the operating range of the operating member. When the endless operating device transitions from a state in which it does not have the operating authority for focusing the lens device to a state in which it has the operating authority, it performs a process called "matching" in which a command value corresponding to the object distance at the time of the transition is set as the command value of the operating device. However, in the endless operating device, if the object distance at the time of the transition is outside the limited range of the object distance in the operating device, the matching cannot be performed. The present invention aims to provide an endless operating device that is advantageous for setting the limited range of the command value and matching the command value, for example.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, in principle (unless otherwise specified) throughout all the drawings for explaining the embodiment, the same members are given the same reference numerals and the repeated description thereof will be omitted.

[0009] [Embodiment 1] Fig. 1 is a diagram showing an example of the configuration of an operation device according to the first embodiment. In Fig. 1, 100 is an operation device, and 200 is a lens device. Here, operation device 100 is an operation device (also called a focus demand) that generates a command value for drive control of a focus lens group as an optical member in lens device 200, but is not limited thereto. In other words, operation device 100 may generate a command value for drive control of an optical member other than the focus lens group (for example, a zoom lens group or an aperture diaphragm).

[0010] In the operation device 100, reference numeral 101 denotes a communication unit, 102 denotes an information acquisition unit, 103 denotes a limit change unit, 104 denotes a limit setting unit, 105 denotes a display unit, 106 denotes an operation member, and 107 denotes a command value generation unit. Here, the components 101 to 104 and 107 may be configured by one or more processors (also referred to as processing units) such as a CPU. The communication unit 101 is connected to the lens device 200, acquires information from the lens device 200, and makes the acquired information public to the information acquisition unit 102. In addition, the communication unit 101 is connected to the command value generation unit 107, and outputs (transmits) a command value generated by the command value generation unit 107 to the lens device 200.

[0011] The information acquisition unit 102 acquires information from the communication unit 101. The information may include an alignment command (also referred to as an alignment instruction or an alignment processing command) from the lens apparatus 200 and information related to a control amount (here, a position) in drive control of an optical member in the lens apparatus 200. The alignment command and the control amount are made public to the limit change unit 103. The control amount is made public to the limit setting unit 104. The alignment command and the operation amount are made public to the command value generation unit 107.

[0012] The limit change unit 103 acquires information about the limit of the range of the command value set by the limit setting unit 104. Furthermore, based on the command for the matching, the control amount, and the limit of the range, the limit change unit 103 changes the limit of the range so that the command value corresponding to the control amount is at the end of the range (changes the limit range of the command value). Furthermore, the limit change unit 103 outputs information about the change to the limit setting unit 104. Details of the change will be described later.

[0013] The limit setting unit 104 includes a user interface, and is for setting a limit on the range of a command value from the operating device 100 (setting a limit range of the command value) based on a user's input via the user interface. The limit setting unit 104 also discloses information on the set limit to the limit change unit 103. The limit setting unit 104 also changes the limit of the command value range and changes a change flag indicating that the change has been made based on information on the changed limit. The limit setting unit 104 also discloses information on the changed limit of the command value range and the change flag to the command value generating unit 107. If the command value corresponding to the control amount acquired by the information acquiring unit 102 is outside the limit range of the command value, the limit setting unit 104 causes the display unit 105 to display that fact.

[0014] The operating member 106 is manually operated by a user, and information on the amount of operation is obtained via a detector such as an encoder and used by a command value generating unit 107 .

[0015] The command value generating unit 107 generates a command value for driving and controlling a focus lens group in the lens device, based on the amount of operation from the operating member 106 and the range of command values ​​set by the limit setting unit 104. The command value generating unit 107 also publishes the command value to the limit setting unit 104. When the command value generating unit 107 recognizes reception of a consistency processing command by the information acquiring unit 102, the command value generating unit 107 sets the command value for the operation device 100 to a command value corresponding to the amount of control acquired by the information acquiring unit 102. The command value generating unit 107 also outputs (transmits) the command value to the lens device 200 via the communication unit 101. The generation of a command value when the limit of the command value range has been changed by the consistency processing will be described later.

[0016] With the above-described configuration, when a matching process command is received from the lens device 200, the limit range of the command value can be reset based on information about the limit range of the command value for which the limit is set by the limit setting unit 104 and the control amount from the lens device 200. Therefore, matching process is possible even if the command value corresponding to the control amount is outside the limit range of the command value. Therefore, even if a limit on the command value range is set in an operation device, it is always possible to grant operation authority to the operation device.

[0017] Here, Fig. 2 is a diagram illustrating a flow of processing related to matching in the first embodiment. Fig. 3 is a diagram illustrating a limit range of a command value. This processing can be performed by the processing unit, for example, periodically, in accordance with a computer program stored in the operation device 100. In Fig. 2, first, in step S201, the limit change unit 103 determines whether a matching processing command has been received from the lens device 200. If a matching processing command has been received, the process proceeds to step S202, and if a matching processing command has not been received, the process ends.

[0018] In step S202, the limit change unit 103 acquires information on the limit range of the command value from the limit setting unit 104, and the process proceeds to step S203. In step S203, the limit change unit 103 acquires information on the control amount from the lens device from the information acquisition unit 102, and the process proceeds to step S204. In step S204, the limit change unit 103 judges whether the command value corresponding to the control amount is within the limit range. Specifically, if the command value is equal to or greater than the end 1-1 of the limit range, the process proceeds to step S205, and if the command value is less than the end 1-1 of the limit range, the process proceeds to step S206. In addition, in step S205, it is judged whether the command value is equal to or less than the end 1-2 of the limit range. If the command value is equal to or less than the end 1-2 of the limit range, the process proceeds to step S210, and if the command value is greater than the end 1-2 of the limit range, the process proceeds to step S207.

[0019] In step S206, the limit change unit 103 sets the command value as the limit range end 2-1, and also sets the limit range end 1-2 as the limit range end 2-2, and the process proceeds to step S208. In step S207, the limit change unit 103 sets the command value as the limit range end 2-2, and also sets the limit range end 1-1 as the limit range end 2-1, and the process proceeds to step S208.

[0020] In step S208, the limit setting unit 104 sets the limit range of the command value from limit range 1 to limit range 2, and the process proceeds to step S209. In step S209, a change flag indicating that the limit range stored in the limit setting unit 104 is being temporarily changed is set to TRUE (or 1), and the process proceeds to step S210. In step S210, the command value generating unit 107 sets the command value as the command value to be output from the operation device 100, and the process ends.

[0021] By the above-mentioned processing, even if the command value corresponding to the control amount is outside the limit range, the matching processing can be performed. For example, FIG. 3(a) shows a case where the command value corresponding to the control amount is smaller than the lower limit (end 1-1) of the command value range (limit range 1). In this case, the command value range (limit range 2) with the command value as the lower limit (end 2-1) is reset, and the matching processing is performed to set the command value as the command value to be output by the operation device. FIG. 3(b) shows a case where the command value corresponding to the control amount is larger than the upper limit (end 1-2) of the command value range (limit range 1). In this case, the command value range (limit range 2) with the command value as the upper limit (end 2-2) is reset, and the matching processing is performed to set the command value as the command value to be output by the operation device.

[0022] Next, Fig. 4 is a diagram illustrating a process flow related to command value generation in the first embodiment. This process is a process related to command value generation when the change flag is TRUE. This process can be performed by the processing unit, for example, periodically, according to a computer program stored in the operation device 100. Fig. 5 is a diagram illustrating a transition of the limit range of the command value. In Fig. 4, first, in step S401, the limit change unit 103 determines whether the change flag is TRUE. If the change flag is TRUE, the process proceeds to step S402, and if the change flag is not TRUE (FALSE or 0), the process is terminated.

[0023] In step S402, the command value generating unit 107 generates a command value based on the operation amount of the operating member 106. In step S403, it is determined whether the command value generated in step S402 is smaller than the end 2-1 of the limit range 2. If the command value is smaller than the end 2-1, the process proceeds to step S404, and if the command value is larger than the end 2-1, the process proceeds to step S405. In step S404, the command value generating unit 107 performs a limiting process to output the value of the end 2-1, and the process proceeds to step S413. In step S405, it is determined whether the command value generated in step S402 is between the end 2-1 and the end 1-1. If the command value is between the end 2-1 and the end 1-1, the process proceeds to step S406, and if the command value is not between the end 2-1 and the end 1-1, the process proceeds to step S407. In step S406, the command value is set to the end 2-1 of the limit range 2, thereby changing the limit range 2, and the process proceeds to step S413.

[0024] In step S407, it is determined whether the command value generated in step S402 is larger than the end 2-2 of the limit range 2. If the command value is larger than the end 2-2, the process proceeds to step S408, and if the command value is smaller than the end 2-2, the process proceeds to step S409. In step S408, the command value generating unit 107 performs a limit process to output the value of the end 2-2, and the process proceeds to step S413. In step S409, it is determined whether the command value generated in step S402 is between the end 2-2 and the end 1-2. If the command value is between the end 2-2 and the end 1-2, the process proceeds to step S410, and if the command value is not between the end 2-2 and the end 1-2, the process proceeds to step S411. In step S410, the command value is set to the end 2-2 of the limit range 2 to change the limit range 2, and the process proceeds to step S413.

[0025] In step S411, since the command value generated in step S402 has returned to within limit range 1, the limit setting unit 104 changes the limit range of the command value from limit range 2 back to limit range 1, and the process proceeds to step S412. In step S412, the limit setting unit 104 changes the change flag stored in the limit setting unit 104 from TRUE to FALSE, and the process proceeds to step S413. In step S413, the command value generation unit 107 outputs the command value determined as described above to the communication unit 101, and the process ends.

[0026] According to this embodiment, it is possible to change the limit range, limit the command value, and return the limit range. As shown in FIG. 5, when the change flag is TRUE, the end 2-1 of the limit range 2 can be changed at any time only in the direction toward the end 1-1 according to the change of the command value, and when the command value falls within the limit range 1, the limit range of the command value can be returned to the limit range 1. In this way, the end of the limit range of the command value may be changed at any time according to the change of the command value, but the limit range of the command value may not be changed until the command value falls within the original limit range. According to this embodiment, it is possible to provide an endless operation device that is advantageous for limiting the range of the command value and matching the command value by at least temporarily changing the limit range of the command value in the matching process.

[0027] [Embodiment 2] FIG. 6 is a diagram illustrating a flow of processing related to matching in the second embodiment. FIG. 7 is a diagram illustrating a limit range of a command value. An example of the configuration of the operation device according to this embodiment is similar to that in FIG. 1 referred to in the first embodiment. The limit change unit 103 changes the limit range based on the matching command, the command value corresponding to the control amount, and the limit range of the command value so that the command value is at the center of the limit range. The limit change unit 103 outputs the changed limit range to the limit setting unit 104. The method of setting the limit range will be described in detail later.

[0028] The limit setting unit 104 determines that the limit range of the command value has been changed by the limit changing unit 103. Furthermore, the limit setting unit 104 outputs (discloses) the changed limit range to the command value generating unit 107.

[0029] With the above-described configuration, when a matching process command is received from the lens device 200, the limit range of the command value can be reset based on information about the limit range of the command value for which the limit is set by the limit setting unit 104 and the control amount from the lens device 200. Therefore, matching process is possible even if the command value corresponding to the control amount is outside the limit range of the command value. Therefore, even if a limit on the command value range is set in an operation device, it is always possible to grant operation authority to the operation device.

[0030] Next, a flow of processing related to matching in the second embodiment will be described with reference to Fig. 6. This processing can be performed by the processing unit, for example periodically, in accordance with a computer program stored in the operation device 100. In Fig. 6, first, in step S601, the restriction change unit 103 determines whether a matching processing command has been received from the lens device 200. If a matching processing command has been received, the process proceeds to step S602, and if a matching processing command has not been received, the process ends.

[0031] In step S602, the limit change unit 103 acquires information on the limit range of the command value (limit range 1) from the limit setting unit 104, and the process proceeds to step S603. In step S603, the limit change unit 103 acquires information on the control amount from the lens device from the information acquisition unit 102, and the process proceeds to step S604.

[0032] In step S604, the limit change unit 103 judges whether the command value corresponding to the controlled variable is within the limit range. If the command value is within the limit range, the process proceeds to step S606. If the command value is not within the limit range, the process proceeds to step S605. In step S605, the limit change unit 103 changes the limit range 1 to the limit range 2 so that the command value is at the center of the limit range, and the process proceeds to step S606. In step S606, the limit setting unit 104 sets the limit range of the command value to the limit range 2, and the process proceeds to S607. In step S607, the command value generation unit 107 sets the command value as the command value output from the operation device 100, and the process ends.

[0033] By the above-mentioned process, even if the command value corresponding to the control amount is outside the limit range, the matching process can be performed. For example, as shown in FIG. 7, when the command value is outside the limit range 1, the limit range 1 is changed (shifted) to the limit range 2 so that the command value is the center of the limit range. By making the command value within the limit range in this way, the matching process is possible. When shifting from the limit range 1 to the limit range 2, if the end of the limit range exceeds the range of the command value (the range from the NEAR end (closest end) to the FAR end (infinitely far end)), the end 1 may be set to the NEAR end or the end 2 may be set to the FAR end. According to this embodiment, by at least temporarily changing the limit range of the command value in the matching process, an endless operating device that is advantageous for limiting the range of the command value and matching the command value can be provided.

[0034] [Embodiment 3] The third embodiment will be described with reference to Figs. 8 to 10. Fig. 8 is a diagram illustrating a process flow relating to matching in the third embodiment. Fig. 9 is a diagram illustrating a process flow relating to the return of the limit range in the third embodiment. Fig. 10 is a diagram illustrating a limit range of a command value. An example of the configuration of the operation device according to this embodiment is similar to that in Fig. 1 referred to in the first embodiment. The limit change unit 103 judges whether the limit is valid or invalid based on the matching command, the command value corresponding to the control amount, and the limit range of the command value. In addition, the limit change unit 103 outputs (discloses) information regarding the validity or invalidity to the limit setting unit 104. Details of the method of validity or invalidity judgment (maximization of the limit range of the command value) will be described later together with details of the matching process and the limit resumption process (limit range setting resumption process).

[0035] The limit setting unit 104 maximizes the limit range of the command value (cancels the setting of a limit range narrower than the maximum range of the command value) based on the valid / invalid information input from the limit changing unit 103. The limit setting unit 104 also determines whether the cancelled setting is valid or invalid based on the command value based on the operation amount of the operating member 106 and the limit range of the command value before the cancellation. The limit setting unit 104 also outputs the valid (setting resumed) limit range of the command value to the command value generating unit 107.

[0036] With the above configuration, when a matching process command is received from the lens device 200, the setting of a limit range narrower than the maximum range of the command value can be released based on information related to the command value limit range set by the limit setting unit 104 and the control amount from the lens device 200. Therefore, matching process is possible even if the command value corresponding to the control amount is outside the command value limit range. Therefore, even if a limit on the command value range is set in an operation device, it is always possible to grant operation authority to the operation device.

[0037] Next, a flow of processing related to matching in the third embodiment will be described with reference to Fig. 8. This processing can be performed by the processing unit, for example periodically, in accordance with a computer program stored in the operation device 100. In Fig. 8, first, in step S801, the restriction change unit 103 determines whether a matching processing command has been received from the lens device 200. If a matching processing command has been received, the process proceeds to step S802, and if a matching processing command has not been received, the process ends.

[0038] In step S802, the limit change unit 103 acquires information on the limit range of the command value from the limit setting unit 104, and the process proceeds to step S803. In step S803, the limit change unit 103 acquires information on the control amount from the lens device from the information acquisition unit 102, and the process proceeds to step S804.

[0039] In step S804, the limit change unit 103 judges whether the command value corresponding to the control amount is within the limit range. If the command value is within the limit range, the process proceeds to step S805. If the command value is not within the limit range, the process proceeds to step S806. In step S805, the limit change unit 103 enables the setting of the command value limit range, and the process proceeds to S808. In step S806, the limit change unit 103 disables the setting of the command value limit range, and the process proceeds to step S807. In step S807, the limit setting unit 104 cancels the setting of the command value limit range, and the process proceeds to S808. In step S808, the command value generation unit 107 sets the command value as the command value output from the operation device 100, and the process is terminated. By the above-mentioned process, even if the command value corresponding to the control amount is outside the limit range, the matching process can be performed by canceling the setting of the command value limit range.

[0040] Next, the restriction restart process will be described with reference to Fig. 9. This process can be performed by the processing unit, for example periodically, in accordance with a computer program stored in the operation device 100. In Fig. 9, first, in step S901, the restriction setting unit 104 determines whether the restriction on the command value range is invalid based on the valid / invalid information input from the restriction changing unit 103. If the restriction is invalid, the process proceeds to step S902, and if the restriction is valid, the process is terminated.

[0041] In step S902, the limit setting unit 104 acquires a command value from the command value generating unit 107, and the process proceeds to step S903. In step S903, the limit setting unit 104 determines whether the command value is within the limit range of the command value. If the command value is within the limit range, the process proceeds to step S904, and if the command value is not within the limit range, the process proceeds to step S905.

[0042] In step S904, the limit change unit 103 enables the limit of the command value range, and the process proceeds to S906. In step S905, the limit change unit 103 leaves the limit of the command value range disabled, and the process ends. In step S906, the limit setting unit 104 resumes the limit of the command value range, and the process ends. Through the above process, the limit range setting of the command value can be released and resumed. For example, as shown in FIG. 10, when the command value is outside the limit range, the setting related to the limit range is released, and thus a matching process can be performed. In addition, when the command value falls within the limit range that was set before the release, the setting related to the limit range can be resumed.

[0043] The cancellation of the limit range setting may involve changing the current limit range to a limit range in which end 1 is the NEAR end (closest end) and end 2 is the FAR end (infinitely far end). In addition, after the limit range setting is cancelled, the setting may not be resumed. According to this embodiment, by at least temporarily changing the limit range of the command value in the matching process (at least temporarily canceling the setting of the limit range), it is possible to provide an endless operating device that is advantageous for setting the limit range of the command value and matching the command value.

[0044] [Embodiment 4] The fourth embodiment will be described with reference to Figs. 11 and 12. Fig. 11 is a diagram showing a configuration example of an operation device according to the fourth embodiment. Fig. 12 is a diagram showing an example of a process flow related to matching in the fourth embodiment. Here, the configuration example of Fig. 11 differs from the configuration example of Fig. 1 in that there is no limit change unit 103, and that the information acquisition unit 102 and the command value generation unit 107 are not connected to each other. Note that the information acquisition unit 102 outputs (publishes) a command for matching from the lens device and a command value corresponding to the control amount from the lens device to the limit setting unit 104. The limit setting unit 104 performs matching processing based on the matching command and the command value. The limit setting unit 104 outputs (publishes) the command value by the matching processing to the command value generation unit 107. Details of the matching processing will be described later. The command value generation unit 107 generates a command value as an output of the operation device 100 based on the operation amount of the operation member 106 and the command value input from the limit setting unit 104.

[0045] With the above configuration, when a matching process command is received from the lens device 200, a command value can be generated based on information about the command value limit range for which limits are set by the limit setting unit 104 and the control amount from the lens device 200. Therefore, even if the command value corresponding to the control amount is outside the command value limit range, matching process is possible. Therefore, even if a command value range limit is set for an operation device, it is always possible to grant operation authority to that operation device.

[0046] Here, a flow of processing related to matching in the fourth embodiment will be described with reference to Fig. 12. This processing can be performed by the processing unit, for example periodically, according to a computer program stored in the operation device 100. In Fig. 12, first, in step S1201, the restriction setting unit 104 determines whether a matching processing command has been received from the lens device 200. If a matching processing command has been received from the lens device 200, the processing proceeds to step S1202, and if a matching processing command has not been received from the lens device 200, the processing ends. In step S1202, the restriction setting unit 104 acquires a command value corresponding to a control amount from the lens device from the information acquisition unit 102, and the processing proceeds to step S1203.

[0047] In step S1203, the limit setting unit 104 determines whether the command value is greater than end 1 of the limit range based on the command value and the limit range of the command value. If the command value is greater than end 1, the process proceeds to step S1204, and if the command value is smaller than end 1, the process proceeds to step S1207.

[0048] In step S1204, the limit setting unit 104 determines whether the command value is smaller than end 2 of the limit range based on the command value and the limit range. If the command value is smaller than end 2, the process proceeds to step S1205, and if the command value is larger than end 2, the process proceeds to step S1206.

[0049] In step S1205, the limit setting unit 104 sets the command value as the command value, and the process proceeds to step S1208. In step S1206, the limit setting unit 104 sets end 2 as the command value, and the process proceeds to step S1208. In step S1207, end 1 as the command value, and the process proceeds to step S1208. In step S1208, the command value generating unit 107 sets the command value as the command value output from the operation device 100, and the process ends. By the above-mentioned process, even if the command value corresponding to the controlled variable is outside the limit range, the command value is changed to the end of the limit range that is closer to the command value (one end closer than the other), so that the matching process can be performed. For example, if the command value is smaller than the lower limit end (end 1) of the limit range of the command value, the process of setting the lower limit end as the command value is performed, and if the command value is larger than the upper limit end (end 2) of the limit range of the command value, the process of setting the upper limit end as the command value is performed. According to this embodiment, by changing the command value within the limited range of the command value in the matching process, it is possible to provide an endless operation device that is advantageous for limiting the range of the command value and matching the command value.

[0050] [Embodiments Related to Optical Devices, Imaging Devices, etc.] FIG. 13 is a diagram showing an example of the configuration of an optical device / imaging device. The optical device 10 includes the operation device (here, 10a) and the lens device (here, 10b) exemplified above. The imaging device includes the optical device 10 and a camera device (imaging device body) 20 having an imaging element 20a that captures (images) an image formed by the optical device 10 (lens device 10b). The camera device 20 includes an imaging unit 20c having the imaging element 20a and a (camera) operation device 20b. The operation device 10a communicates with the lens device 100 by wire or wirelessly as a remote control device. The camera device 20 may have a function of transmitting a command value for an optical member. The camera device 20 may generate the command value by, for example, an autofocus function or an autoiris function of the camera device 20. The operation device 20b communicates with the imaging unit 20c by wire or wirelessly as a remote control device. Furthermore, the operation device 20a and the operation device 20b can generate at least one of a command value corresponding to an object distance of the lens device, a command value corresponding to a focal length or zooming of the lens device, a command value corresponding to an effective aperture of the lens device, etc. According to this embodiment, for example, it is possible to provide an optical device or an imaging device that is advantageous in limiting the range of the command value and matching the command value.

[0051] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, when a command value corresponding to a control amount received from a lens device is outside a limited range of the command value, the processing unit in the operation device may change at least one of the command value and the range so that the command value is within the limited range. Then, the processing unit may generate a command value obtained by changing the command value due to the change, or a command value that is not changed due to the change. It is also preferable that the processing unit displays information regarding the at least one change on the display unit. It is also preferable that the processing unit transmits (sends) information regarding the at least one change to a lens device or a camera device. It is also possible that the processing unit is capable of selectively performing the matching process in the above-mentioned first to fourth embodiments. [Explanation of symbols]
