[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Example]

[0009] 1 shows the configuration of a focus control system according to the first embodiment. An analog controller 10 serving as an operating device (external device) is connected to a lens device 20 serving as an optical device. The lens device 20 is detachably connected to a camera C serving as an imaging device including an image sensor IS. The image sensor IS is composed of a CCD sensor, a CMOS sensor, or the like, and photoelectrically converts (captures) an optical image formed by an imaging optical system (not shown) in the lens device 20 to generate a video signal.

[0010] The operation knob 101 of the analog controller 10 is an operation member that is rotated by a user (a cameraman or other operator) who instructs the driving of a focus lens 208 included in the imaging optical system of the lens device 20. The operation knob 101 has a rotatable range (0° to 359°) that is an operable range, and both ends of the range are mechanically limited. The position detection unit 102 is a position sensor such as a potentiometer or rotary encoder that detects the rotation position (operation position) of the operation knob 101, and outputs a knob position signal corresponding to the operation position of the operation knob 101. The command voltage generation unit 103 generates an analog command voltage as a drive command corresponding to a change in the knob position signal input from the position detection unit 102. The analog command voltage generated by the command voltage generation unit 103 is output to the lens device 20 via a cable.

[0011] The lens device 20 has a lens CPU (control means) 200. The lens CPU 200 includes an A / D conversion unit 201, a drive command generation unit 202, a drive command conversion unit 203, a restriction information setting unit 204, a function invalidity determination unit 205, a focus drive position calculation unit 206, and a focus control unit 207.

[0012] The A / D conversion unit 201 converts the analog command voltage input from the analog controller 10 into a digital command signal and outputs the digital command signal to the lens CPU 200. The drive command generation unit 202 calculates a drive command value (first command value) for the focus lens 208 from the digital command voltage input from the A / D conversion unit 201 and outputs the drive command value to the drive command conversion unit 203.

[0013] The limit information setting unit 204 sets and stores the maximum and minimum values ​​of the drive command value as limit information (setting information). For example, in response to a user operating a setting switch (not shown), the limit information setting unit 204 sets the drive command value currently input as the maximum or minimum value of the drive command value as limit information. The limit information setting unit 204 outputs the set limit information to the drive command conversion unit 203.

[0014] Furthermore, by operating a limit switch (selection means) 215 provided on the lens device 20, the user can select between a limited state in which stored limit information is used in response to the operation of the setting switch and a non-limited state in which default limit information is used. The default limit information is the maximum and minimum values ​​that a drive command value can take, and in the non-limited state in which this default limit information is used, no limit is actually imposed on the drive command value. The user can select (input) either the limited state or the non-limited state depending on the imaging situation, etc. The function of limiting the drive command value to limit the drivable range of the focus lens 208 in the limited state is a first function related to drive control of the focus lens 208, and is hereinafter referred to as the limit function. In other words, the limit switch 215 is a switch that allows the user to select whether to use or not use the limit function.

[0015] The limit switch 215 may be a switch that performs a switching operation, or may be a touch sensor that allows the user to select "use" or "non-use" on the display by touch operation.

[0016] The function invalidation determination unit (invalidation means) 205 determines whether to enable or disable the restriction function, regardless of the user's selection using the restriction switch 215, and switches between enable and disable the restriction function according to the determination result. This determination will be described later.

[0017] When the limiting function is enabled and the limiting state is selected by the limiting switch 215, the drive command converting unit 203 converts the drive command value input from the drive command generating unit 202 into a value (second command value) that is limited so as not to exceed a maximum value or fall below a minimum value as limiting information. Then, the drive command converting unit 203 outputs the limited drive command value to the focus drive position calculating unit 206.

[0018] The focus drive position calculation unit 206 calculates a target position of the focus lens 208 from the input drive command value and outputs this to the focus control unit 207. The focus control unit 207 generates a control signal for driving the focus lens 208 to the input target position, and controls a focus actuator (not shown) that drives the focus lens 208 based on the control signal.

[0019] The focus position detection unit 209 is a position sensor that detects the position of the focus lens 208, and outputs a focus position signal according to the position of the focus lens 208 to the focus control unit 207. The focus control unit 207 performs feedback control of the focus actuator so that the position indicated by the focus position signal reaches the target position.

[0020] The communication unit 210 is provided for transmitting and receiving information to and from a digital controller when the digital controller described below is connected.

[0021] 2 shows the lens control process executed by the lens CPU 200 as a computer according to a program. Note that, in a step (not shown) in which the use of the limiting function by the limit switch 215 is selectable, it is assumed that the use of the limiting function is selected, and that the limiting information is set in advance in the drive command conversion unit 203.

[0022] In step S101, the lens CPU 200 converts the analog command voltage input from the analog controller 10 into a digital command signal by the A / D conversion unit 201, and acquires the digital command signal by the drive command generation unit 202. In this embodiment, an analog command voltage of 0 to 5 V is input from the analog controller 10 according to the rotation position of the operation knob 101 within the rotatable range of 0° to 359°, and the digital command signal is a value obtained by converting the analog command voltage of 0 to 5 V into a value of 0 to 10,000.

[0023] Next, in step S102, the lens CPU 200 (drive command generation unit 202) generates a drive command value from the digital command voltage, and the drive command value is acquired by the drive command conversion unit 203. The generated drive command value indicates the entire driveable range of the focus lens 208 with values ​​from 0 to 10,000.

[0024] Next, in step S103, the lens CPU 200 (drive command conversion unit 203) converts the drive command value (first command value) based on the restriction information. Details of this process will be described later. The converted drive command value (second command value) is acquired by the focus drive position calculation unit 206.

[0025] Next, in step S104, the lens CPU 200 (focus drive position calculation unit 206) generates a control signal based on the drive command value acquired in step S103 and the position of the focus lens 208 detected by the focus position detection unit 209. Then, the control signal is output to the focus control unit 207 to drive the focus lens 208, and this process ends.

[0026] Next, the processing performed in step S103 will be described with reference to FIGS. 3(a) and 3(b). FIG. 3(a) shows the drive command value (first command value) generated by the drive command generating unit 202 with respect to the position of the operation knob 101 when the non-restricted state is selected. In this case, there is a one-to-one correspondence between the rotation position of the operation knob 101 within the entire rotatable range (0° to 359°) and the drive command value (0 to 10000). That is, one drive command value is generated for each rotation position of the operation knob 101. In this case, the drive command value indicates the position of the focus lens 208 within the entire drivable range. When the drive command value is 0, the position of the focus lens 208 is the closest end (MOD), and when the drive command value is 10000, the position of the focus lens 208 is the infinity end (INF). Because there is a one-to-one correspondence between the rotation position of the operation knob 101 and the drive command value, the user operating the operation knob 101 can intuitively recognize the relationship between the rotation position and the position of the focus lens 208 to be driven.

[0027] In Fig. 3(b), the solid line indicates the drive command value (second command value) generated by the drive command conversion unit 203 when the restricted state is selected, and the dashed line indicates the drive command value shown in Fig. 3(a). The range from P1 to P2 indicates the subject distance range in which you want to focus and capture an image, and any other subject distance range is outside the range of the subject that you want to capture.

[0028] In this case, the drive command value is converted according to the following (Equation 1), where Oin is the drive command value (first command value) corresponding to the rotational position of the operating knob 101, Omin is the minimum value of the drive command value in the restriction information, Omax is the maximum value, and Oout is the converted drive command value (second command value).

[0029]

number

[0030] In this way, the limiting function of the lens device 20 converts drive command values ​​below the minimum value and drive command values ​​above the maximum value into the minimum and maximum values ​​in the limiting information, respectively, thereby limiting the driveable range (subject distance range) of the focus lens 208 to a setting range whose ends are the minimum and maximum values ​​in the limiting information.

[0031] 4 shows the configuration of a lens control system in which a digital controller 30 serving as a specific operating device (external device) is connected to a lens device 20 instead of the analog controller 10 in FIG. The configurations of the lens device 20 and the camera C are the same as those in FIG.

[0032] The operation knob 301 of the digital controller 30 is an operation member that is rotated by the user to instruct driving of the focus lens 208. Both ends of the rotatable range (0° to 359°) of the operation knob 301 are mechanically limited. The position detection unit 302 includes a position sensor such as a potentiometer or rotary encoder that detects the rotation position (operation position) of the operation knob 301, and an A / D converter (not shown), and outputs a knob position signal as a digital signal corresponding to the amount of operation of the operation knob 301.

[0033] The digital controller 30 includes a controller CPU 300. The controller CPU 300 includes a drive command generation unit 303, a restriction information setting unit 304, and a drive command conversion unit 305.

[0034] A drive command generating section (generating means) 303 calculates a drive command value (first command value) for the focus lens 208 from a knob position signal from the operation knob 301 , and outputs this to a drive command converting section 305 .

[0035] The limit information setting unit 304 sets and stores the maximum and minimum values ​​of the drive command value as limit information (setting information). For example, in response to a user operating a setting switch (not shown), the limit information setting unit 304 sets the drive command value currently input as the maximum or minimum value of the drive command value as limit information. The limit information setting unit 304 outputs the set limit information to the drive command conversion unit 305.

[0036] Furthermore, by operating a limit switch (selection means) 315 provided on the digital controller 30, the user can select between a limited state in which stored limit information is used in response to the operation of the setting switch, and a non-limited state in which default limit information is used. The default limit information is the maximum and minimum values ​​that the drive command value can take, and in the non-limited state in which this default limit information is used, no limit is actually imposed on the drive command value. The user can select (input) either the limited state or the non-limited state depending on the imaging situation, etc. In other words, the digital controller 30 also has a limit function as a first function, and the limit switch 315 is a switch that makes it possible to select whether to use or not use the limit function.

[0037] The limit switch 315 may be a switch that performs a switching operation, or may be a touch sensor that allows the user to select "use" or "non-use" on the display by touch operation.

[0038] When the limit switch 315 selects the limited state, the drive command conversion unit 305 converts the drive command value input from the drive command generation unit 303 into a value (second command value) that is limited so as not to exceed a maximum value or fall below a minimum value as limit information. That is, the drive command conversion unit 305 generates a drive command value that corresponds to the limit function of the lens device 20. The drive command conversion unit 305 then outputs this drive command value to the communication unit 306.

[0039] The communication unit 306 encodes the input drive command value into a drive command in a communication command format and transmits this to the communication unit 210 of the lens apparatus 20. The communication unit 210 of the lens apparatus 20 transmits and receives commands to the communication unit 306 of the digital controller 30 via wired or wireless communication. The communication unit 210 decodes the received drive command and converts it into a drive command value, which is output to the drive command generation unit 202 of the lens CPU 200. The configuration and operation of the lens CPU 200 are the same as those described using FIG. 1.

[0040] In this way, the lens device 20 can be connected not only to the analog controller 10 but also to the digital controller 30, and can drive the focus lens 208 in response to the operation of the operation knob 301 of the digital controller 30. Furthermore, the digital controller 30 of this embodiment is configured so that a function equivalent to a limiting function can be used even if the lens device is not provided with a limiting function.

[0041] However, if the lens device 20 has a limiting function (first function) and the digital controller 30 also has a function equivalent to the limiting function of the lens device 20 (second function: hereinafter also referred to as the limiting function), and if the use of both limiting functions is selected, the limiting functions will conflict with each other. As a result, the focus lens 208 may be driven unintentionally by the user. Therefore, in this example, the lens device 20 (lens CPU 200) switches between enabling and disabling its own limiting function depending on the type of demand (whether or not it is a digital demand with a limiting function, etc.) with which it is connected. Note that the limiting function of the digital controller 30 equivalent to the limiting function of the lens device 20 may be exactly the same as the limiting function of the lens device 20, or may be a function that is slightly different but basically or substantially the same.

[0042] 5 shows the function disable process (disabling process, control method) performed by the lens CPU 200 (function disable determination unit 205). As described above, the function disable determination unit 205 executes this process regardless of whether or not the use of the restriction function of the lens device 20 is selected by the restriction switch 215.

[0043] In step S201, the function invalidity determination unit 205 determines the type of controller connected to the lens device 20. That is, it determines whether it is the digital controller 30 or the analog controller 10. For example, it can be determined that the digital controller 30 is connected when the communication unit 210 performs initial communication with the communication unit 306. It can also be determined that the analog controller 10 is connected when an analog command voltage (initial voltage) is input to the A / D conversion unit 201. Furthermore, the user may input information indicating whether the controller connected to the lens device 20 is a digital controller or an analog controller, and the determination may be made based on that input. If the function invalidity determination unit 205 determines that a digital controller is connected, it performs the process of step S202, and if it determines that an analog controller is connected, it ends this process.

[0044] In step S202, the function invalidation determination unit 205 invalidates the limiting function of the lens device 20, and disables the limiting of the drive command value by the drive command conversion unit 203. In other words, even if the use of the limiting function is selected by the limit switch 215, the initial setting limiting information is used instead of the limiting information set and stored by the limiting information setting unit 204. This prevents the lens device 20 from limiting the drive command value. Then, this process ends.

[0045] In this way, in this embodiment, the limiting function of the lens device 20 is switched between enabled and disabled depending on the type of controller (whether or not the limiting function is present) connected to the lens device 20. This prevents the same functions of the lens device and the controller from being used together, causing conflicts between them and causing operations that are not intended by the user.

[0046] In this embodiment, an example has been described in which the analog controller does not have a limiting function and the digital controller does have a limiting function. However, there are cases in which a digital controller with a limiting function and a digital controller without a limiting function can be connected to a lens device. In this case, the presence or absence of the limiting function may be determined based on identification information, etc., obtained from the connected digital controller, and the limiting function of the lens device may be enabled or disabled depending on the determination result.

[0047] In addition, in this embodiment, an example has been described in which the use or non-use of the limit function of the lens device 20 can be selected by the limit switch 215 provided on the lens device 20. However, as a selection means instead of the limit switch 215, a means that allows selection of use of either the limit function of the lens device 20 or the limit function of the digital controller 30 may be used. In this case, the function disable determination unit 205 may disable the limit function of the lens device 20 when use of the limit function of the digital controller 30 is selected. Furthermore, the function disable determination unit 205 may disable the limit function of the digital controller 30 when use of the limit function of the lens device 20 is selected.

[0048] In addition, in this embodiment, an example has been described in which the lens device 20 has the function disable determination unit 205. However, the function disable determination unit may be provided in the digital controller, and when the user selects to use the restriction function of the digital controller, the restriction function of the lens device may be disabled by sending a disable request to the lens device. Also, when the user selects to use the restriction function of the lens device 20, the restriction function of the digital controller itself may be disabled.

[0049] In this embodiment, the function for limiting the drive range of the focus lens has been described. However, the function for limiting the drive range of optical elements such as a zoom lens or an iris may also be enabled or disabled. Furthermore, the enable / disable switching is not limited to the function for limiting the drive range of an optical element, and other functions may also be enabled or disabled. Examples of other functions include, for example, a function for allocating the entire operational range of an operating element to the drive range (i.e., setting the drive amount of the focus lens per unit operation amount of the operating knob) to enable fine adjustment of the position of the optical element within the limited drive range. Furthermore, a function for driving the optical element to a pre-stored setting position in response to switch operation may also be used. In this way, when a lens device and a controller connected thereto have corresponding functions, it is possible to select whether to disable one of the functions to avoid conflicts between them.

[0050] In this embodiment, a controller equipped with an operation knob having both ends (operation ends) within an operable range is described, but a controller equipped with an operation knob without an operation end may also be used. [Example]

[0051] Next, a description will be given of Example 2. The configuration of the lens control system in this example is the same as the configuration shown in FIGS.

[0052] The flowchart in Fig. 6 shows the setting change process that is repeatedly executed at a predetermined cycle by the lens CPU 200. As in Fig. 5, if the controller connected to the lens device 20 in step S201 is the digital controller 30, the function disable determination unit 205 disables the restriction function of the lens device 20 in step S202.

[0053] Next, in step S301, the lens CPU 200 transmits (outputs) the restriction information stored in the restriction information setting unit 204 via the communication unit 210 to the digital controller 30 (controller CPU 300).

[0054] Next, in step S302, the lens CPU 200 determines whether or not the communication connection between the lens device 20 and the digital controller 30 has been disconnected. If the communication connection has been disconnected, this process ends, and if the communication connection has not been disconnected, the lens CPU 200 performs the process of step S303.

[0055] In step S303, the lens CPU 200 determines whether the maximum or minimum value of the drive command value in the restriction information has been updated by the user operating the setting switch provided on the lens device 20. If the restriction information has been updated, the process proceeds to step S304; if it has not been updated, the process of step S302 is repeated.

[0056] In step S304, similarly to step S301, the lens CPU 200 transmits the updated and stored restriction information by the restriction information setting unit 204 to the digital controller 30 via the communication unit 210. Then, the process of step S302 is repeated.

[0057] In this way, when the digital controller 30 is connected to the lens device 20 and the restriction function of the lens device 20 is disabled, the stored restriction information is transmitted from the lens device 20 to the digital controller 30. The controller CPU 300 (drive command conversion unit 305) receives a drive command value corresponding to the operation of the operation knob 301 from the lens device 20, and converts it into a drive command value that is restricted based on the restriction information stored in the restriction information setting unit 304. Also, when the restriction information is changed (updated) in the lens device 20, the changed restriction information is transmitted to the digital controller 30. The controller CPU 300 converts the drive command value corresponding to the operation of the operation knob 301 into a drive command value that is restricted based on the updated restriction information.

[0058] The flowchart in Fig. 7 shows a setting change process that the controller CPU 300 repeatedly executes at a predetermined cycle in response to the process in Fig. 6 executed by the lens CPU 200. In step S401, the controller CPU 300 determines whether or not restriction information has been received (restriction information has been input) from the lens device 20 via the communication unit 306. If restriction information has been received, the controller CPU 300 executes the process in step S402, and if restriction information has not been received, the controller CPU 300 executes the process in step S403.

[0059] In step S402, the controller CPU 300 updates the restriction information that has been stored in the restriction information setting unit 304 to the restriction information received from the lens device 20. Then, this process ends.

[0060] In step S403, the controller CPU 300 determines whether or not a user operation (i.e., a setting operation for setting the restriction information) has been performed on the setting switch provided on the digital controller 30. If a setting operation has been performed, the process of step S404 is performed, and if a setting operation has not been performed, this process is terminated.

[0061] In step S404, the limit information setting unit 304 sets and stores the current drive command value as the maximum or minimum value of the limit information, and then ends this process.

[0062] In this way, when the digital controller 30 receives restriction information from the lens device 20, it updates the previous restriction information with the received restriction information. Furthermore, when the user performs a setting operation for restriction information on the digital controller 30, the restriction information is also updated.

[0063] That is, in this embodiment, when the restriction function of the lens device 20 is disabled, the restriction information is updated by the digital controller 30 where the restriction function is enabled, regardless of whether the restriction information is updated by the lens device 20 or the digital controller 30. Therefore, the user can update the restriction information without being aware of which restriction function is enabled or disabled, improving the usability of the lens control system.

[0064] In this embodiment, an example has been described in which the restriction information when the restriction function is disabled and the restriction information updated after the function is disabled are transmitted from the lens device 20 to the digital controller 30. However, instead of transmitting the restriction information, an instruction to update the restriction information may be transmitted from the lens device 20 to the digital controller 30, and the restriction information may be set (updated) in the digital controller 30 in accordance with the update instruction.

[0065] In this embodiment, an example has been described in which, when the restriction information is updated in a lens device 20 in which the restriction function is disabled, the updated restriction information is transmitted to the digital controller 30. However, the present invention is not limited to this, and the user may be notified that the restriction information cannot be updated in a lens device 20 in which the restriction function is disabled.
