The focus controller 10 as an operating device is an operating device for operating the lens device 20 as a lens device as an external device of the focus controller 10. The lens device 20 has a focus lens 204 which is an optical member. The focus controller 10 includes an operation unit 101 having an operation member (not shown) and an output generation unit 102 as a processing unit. The focus controller 10 further includes a communication unit 103, a sensitivity changing unit 104, and a sensitivity management unit 105. The focus controller 10 is, for example, a microcomputer provided with a communication function for performing serial communication with the lens device 20, a non-volatile memory for storing data, and the like. The lens device 20 may be configured not as an external device of the focus controller 10 but as a lens device 20 including the focus controller 10. Further, the lens device 20 may be configured as an image pickup device (not shown) having an image pickup element (not shown) for taking an image formed by the focus lens 204 which is an optical member of the lens device 20.

The operation unit 101 is connected to the output generation unit 102 and outputs the operation amount. The operation amount indicates the amount operated by the user to operate the focus lens 204 of the lens device 20. The operating member of the operating unit 101 has a structure that can be rotated for operation. In the operation unit 101, when the operation member is rotated by the rotation operation, the rotation position changes. Further, the operation unit 101 includes, for example, a potentiometer or a rotary encoder that detects a rotation position. The operation unit 101 detects an operation amount by the user indicating how much the user has rotated the operation member, and generates this as an operation amount. The operation unit 101 detects the rotation position of the operation member at regular time intervals, compares the rotation positions before and after the lapse of a certain time, and outputs the changed rotation position as a polar operation amount. do. In general, the positive direction of polarity can be clockwise (hereinafter, CW direction). For example, in the first embodiment, assuming that the changed rotation position is advanced by 10 ° in the clockwise direction, +10 is the operation amount. On the other hand, assuming that the vehicle has traveled by −20 ° in the counterclockwise direction (hereinafter referred to as CCW direction), −20 is the operation amount.

The output generation unit 102, which is a processing unit, is connected to the communication unit 103. The output generation unit 102 generates a command for controlling the drive of the focus lens 204 based on the operation amount of the operation member. The output generation unit 102 outputs the generated command to the communication unit 103. The focus position is also input to the output generation unit 102. Further, the output generation unit 102 is connected to the sensitivity management unit 105. The focus controller 10 has an instruction member (not shown) which is a member for inputting operation sensitivity. The instruction member is a member that instructs the amount of change in the operation sensitivity as a change in the value of the command for controlling the drive of the focus lens 204 with respect to the change in the operation amount of the operation member. The operation sensitivity is input to the sensitivity management unit 105 by the indicating member.

When the operation amount is input to the sensitivity management unit 105, the sensitivity management unit 105 generates a drive command from the input operation amount, the focus position, and the operation sensitivity. The sensitivity management unit 105 can make the operation sensitivity different for each instruction of changing the operation sensitivity by the instruction member. The operation sensitivity is a value indicating the magnitude of the drive amount of the focus lens 204 per the operation amount, and is represented by a positive integer in the first embodiment. The generation of the drive command value will be described later. The instruction member can instruct the change of the operation sensitivity during the control of the drive of the focus lens 204.

The communication unit 103 is connected to the communication unit 201, transmits a drive command command of the focus lens 204 or information on the focus position of the focus lens 204, and receives a focus position command. Further, it is connected to the sensitivity management unit 105 and outputs the focus position. When a drive command is input, it is encoded into a communication command format, generated as a drive command command, and transmitted. When a focus position command is received, it is decoded to generate a focus position and output.

The sensitivity changing unit 104 is connected to the sensitivity management unit 105, accepts a change to the operation sensitivity to be applied, and outputs the sensitivity change information. Further, the sensitivity changing unit 104 includes a fine adjustment button (not shown) and a coarse adjustment button (not shown). Each time the fine adjustment button is pressed, sensitivity change information that reduces the change in the drive command per operation amount is generated and output. Each time the coarse adjustment button is pressed, sensitivity change information that increases the change in the drive command per operation amount is generated and output. The operating sensitivity in Example 1 takes a value of 1 to 1000. In the first embodiment, in each operation by the sensitivity changing unit 104, the coarse adjustment button generates and outputs the sensitivity change information that doubles the operation sensitivity, and the fine adjustment button doubles the operation sensitivity. The sensitivity change by the button operation provided in the sensitivity change unit 104 will be described later.

The sensitivity management unit 105 can make the operation sensitivity different for each instruction of changing the operation sensitivity by the instruction member. The sensitivity management unit 105 can change the operation sensitivity based on the control amount of the focus lens 204. The sensitivity management unit 105 determines one operation sensitivity to be applied from one or more operation sensitivities stored according to the input focus position. It also outputs the determined operation sensitivity. Further, when the sensitivity change information is input, the operation sensitivity determined according to the focus position is changed according to the content of the sensitivity change information and stored. In the first embodiment, as described below, the instruction by the instruction member is selected from the operation sensitivity conditions and operation sensitivities determined according to the focus position, which are set in advance as set values or setting ranges. It can be configured to be possible. For example, when the focus position is "0 or more and 3333 or less", the operation sensitivity A is applied. When it is "3334 or more and 6666 or less", the operation sensitivity B is applied. When it is "6667 or more and 10000 or less", the operation sensitivity C is applied. In this way, each has a different value of operation sensitivity, and it is determined which operation sensitivity is output or changed and stored according to the focus position. For example, 100 is preset for the operation sensitivity A, 50 is set for the operation sensitivity B, and 25 is set for the operation sensitivity C in advance. The values preset for these operating sensitivities can be selected as arbitrary values according to the characteristics of the lens device 20. This is set because the depth of focus is shallower on the near side than on the infinite side, and the ease of focusing is improved by allowing a larger amount of operation to be used for focusing.

Next, the lens device 20 as the lens device will be described. The lens device 20 includes a communication unit 201, a focus drive position calculation unit 202, a focus control unit 203, a focus lens 204 as a lens member, and a focus position detection unit 205. The lens device 20 is composed of a microcomputer provided with a communication function for performing serial communication with the focus controller 10 and a non-volatile memory for storing data. The focus lens 204 is a lens member as a movable optical member, and forms an image of an object at a predetermined position.

The communication unit 201 is connected to the communication unit 103, receives a drive command command, and transmits a focus position command. Further, it is connected to the focus drive position calculation unit 202 and outputs a drive command. Further, it is connected to the focus position detection unit 205 and the focus position is input. When a drive command command is received, it is decoded into a drive command and output. When the focus position is input, it is encoded in the focus position command and sent.

The focus drive position calculation unit 202 is connected to the focus control unit 203, and calculates and outputs a drive position command of the focus lens 204 from the input drive command.

The focus control unit 203 is connected to the focus position detection unit 205, and the focus position is input. Further, it is connected to the focus lens 204 and is driven based on the generated drive signal. When a drive position command is input, a drive signal is generated while feedback control is performed from the drive position command and the focus position.

The focus position detection unit 205 is a position sensor that detects the position of the focus lens 204, and outputs the detected focus position. With this configuration, the operation unit 101 outputs the operation amount according to the amount operated by the user. The output generation unit 102 outputs a drive command from the input focus position, operation amount, and operation sensitivity. The communication unit 103 converts the drive command into a drive command command and transmits the drive command to the lens device 20 via the communication unit 201. The lens device 20 drives the focus lens 204 based on the drive command input via the drive command command. Further, the sensitivity change unit 104 generates and outputs sensitivity change information each time the user operates until the current operation sensitivity becomes as expected. The sensitivity management unit 105 changes and stores the operation sensitivity from the input focus position and sensitivity change information. As a result, the user can set the desired operation sensitivity for each focus position while operating the focus lens 204.

Next, the drive command generated from the focus position, the operation amount, and the operation sensitivity will be described. When the lens device 20 is at the position of 3000, when the operation sensitivity is 100, and the input operation amount is +10, the operation amount is multiplied by the operation sensitivity to calculate a value of +1000, and the current focus position is obtained. Generate a drive command of 4000 added together. Similarly, if the operation amount is -10 and the operation sensitivity is 50, the operation amount is similarly multiplied by the operation sensitivity to calculate a value of -500, and a drive command of 3500 added to the current focus position is generated.

The relationship between the drive command and the position of the focus lens 204 of the lens device 20 will be described with reference to FIG. 2A. In FIG. 2A, the horizontal axis X indicates a drive command output by the focus controller 10, and the vertical axis Y indicates the position of the focus lens 204 of the lens device 20. In the lens device 20, the position of the focus lens 204 is expressed by a value from 0 to 10000 from the near end (MOD) to the infinite end (INF), which is the entire range of the drive range for driving the focus position of the focus lens 204. The focus controller 10 outputs a drive command having a value of 0 to 10000, which is the same as the range in which the focus lens 204 is driven, and the lens device 20 receiving the drive command drives the focus lens 204. For example, when the lens device 20 is driven to the lens position of 8000 when the lens device 20 is at the position of 5000, the focus controller 10 outputs a drive command having a value of 8000. The lens device 20 that has received the drive command of 8000 drives the focus lens 204 at the position of 8000. The relationship between the focus position and the drive command is the same.

Next, using FIG. 2B, the relationship between the manipulated variable and the position of the focus lens 204 of the lens device 20 will be described. In FIG. 2B, the horizontal axis X indicates the amount of operation of the operation unit 101, and the vertical axis Y indicates the focus position. As described above, the focus position of the focus lens 204 and the drive command of the focus controller 10 match. Further, since the drive command is uniquely determined once the current focus position and the operation sensitivity are determined, the relationship between the operation amount and the focus position as shown in FIG. 2B is established. The point P1 on the straight line L indicates the focus position when the operation amount +10 is given from the point P0 on the straight line L. This calculates a value of +1000 by multiplying the operation amount by the operation sensitivity when the operation sensitivity is 100 and the input operation amount is +10 when the focus position is 5000. Then, a drive command of 6000 added to the current focus position is generated, which indicates that the focus position changes.

Next, the operation sensitivities that change when one or more operation sensitivities stored in the sensitivity management unit 105 are applied in each position range will be described with reference to FIGS. 3 (a) and 3 (b). In FIGS. 3A and 3B, the horizontal axis X indicates the amount of operation of the operation unit 101, and the vertical axis Y is the focus position of the focus lens 204 of the lens device 20. Like the range divided by the broken line in FIG. 3B, the threshold value of the condition for determining the operation sensitivity from one or more operation sensitivities in each range is shown. In this example, it is assumed that the operation sensitivity A, the operation sensitivity B, and the operation sensitivity C are applied as one or more operation sensitivities in a separated range, respectively. The straight line having an intersection with the vertical axis shows the relationship between the operation amount and the change amount of the focus position when the operation is started at a certain focus position. FIG. 3A shows the range of the operation sensitivity B.

In FIG. 3A, the user operates the fine adjustment button of the sensitivity changing unit 104 at a certain focus position, changes the operation sensitivity, then starts the operation to change the focus position, and changes the operation sensitivity again. It shows the changes in the amount of operation of the use case and the amount of change in the focus position. The intersection of the vertical axis Y and the straight line A is the point at which the operation is started. First, the user changes the operation sensitivity. At this time, the operation amount and the change amount of the focus position change from the straight line A to the straight line B obtained by multiplying the operation sensitivity by 0.5. Next, the operation amount is given by the relationship of the straight line B, and the focus position is changed. At this time, the operation amount and the change amount of the focus position change from the straight line B to the straight line B'. Next, the operation sensitivity is changed again. At this time, the operation amount and the change amount of the focus position change from the straight line B'to the straight line C obtained by multiplying the operation sensitivity by 0.5. By repeating the change of the operation sensitivity in this way, the user can change and set the desired operation sensitivity for each focus position range.

FIG. 3B shows that when the user operates the fine adjustment button of the sensitivity changing unit 104 at a certain focus position and the operation sensitivity is changed, the operation amount and the focus position are changed by different operation sensitivities according to the focus position. It shows that the relationship of quantities changes. The intersection of the vertical axis Y and the straight line C is a point at which the operation is started within the applicable range of the operation sensitivity C. The user changes the operation sensitivity within the applicable range of the operation sensitivity C. At this time, the operation amount and the change amount of the focus position change from the straight line C to the straight line D. The intersection of the vertical axis Y and the straight line E is a point at which the operation is started within the applicable range of the operation sensitivity A. The user changes the operation sensitivity within the applicable range of the operation sensitivity A. At this time, the operation amount and the change amount of the focus position change from the straight line E to the straight line F. By changing the operation sensitivity at different focus positions in this way, the user can change and set different operation sensitivities for each focus position range.

Subsequently, with reference to FIG. 4, a process of determining the operation sensitivity in the sensitivity management unit 105 of the focus controller 10 of the first embodiment will be described. This process determines the operation sensitivity based on the focus position of the focus lens 204. First, in S101, the sensitivity management unit 105 determines whether or not the focus position has been input (S101). Here, if the focus position has not been input, the sensitivity management unit 105 determines again whether or not the focus position has been input. On the other hand, when the focus position is input, the sensitivity management unit 105 determines whether the focus position is 0 or more and 3333 or less (S102).

When the sensitivity management unit 105 determines that the focus position is 0 or more and 3333 or less, the sensitivity management unit 105 determines the operation sensitivity to the operation sensitivity A (S103), and ends the process. On the other hand, when the sensitivity management unit 105 determines that the focus position is not 0 or more and 3333 or less, it determines whether the focus position is 3334 or more and 6666 or less (S104). When the sensitivity management unit 105 determines that the focus position is 3334 or more and 6666 or less, the operation sensitivity is determined to be the operation sensitivity B (S105), and the process is terminated. On the other hand, when the sensitivity management unit 105 determines that the focus position is not 3334 or more and 6666 or less, it determines the operation sensitivity to the operation sensitivity C (S106) and ends the process. By doing so, it is possible to select the operation sensitivity to be applied from one or more operation sensitivities. Then, if a drive command is generated based on the operation sensitivity and the operation amount according to the focus position, the change in the focus position of the focus lens 204 per the operation amount is changed for each focus position by changing the operation sensitivity. be able to.

Subsequently, the process in the focus controller 10 of the first embodiment will be described with reference to FIG. This process generates an operation amount according to a change in the rotation position due to a knob operation in the operation unit 101 by the user, generates a drive command based on the operation sensitivity, and outputs the drive command to the lens device 20. Here, it is assumed that the focus position is 5000.

First, in S201, the sensitivity management unit 105 determines the operation sensitivity based on the focus position and outputs the operation sensitivity to the output generation unit 102 (S201). Subsequently, the operation unit 101 detects a change in the rotation position of the operation member (not shown), generates an operation amount, and outputs the operation amount to the output generation unit 102 (S202). The operation amount of the first embodiment is +10 generated by rotating the operation unit 101 by 10 degrees in the CW direction. The output generation unit 102 generates a drive command according to the operation amount and the operation sensitivity (S203), and outputs this to the communication unit 103. The drive command of the first embodiment is 6000, which is obtained by multiplying the operation amount +10 and the operation sensitivity 100 to calculate +1000 and adding it to the current focus position of 5000. The communication unit 103 encodes the input drive command into a communicable communication command format, transmits it to the lens device 20 (S204), and ends the process. In this way, if a drive command is generated based on the operation sensitivity and the operation amount according to the focus position, the change in the focus position of the focus lens 204 per the operation amount can be changed for each focus position by changing the operation sensitivity. Can be changed.

Next, with reference to FIG. 6, a process of changing and storing the operation sensitivity of the sensitivity management unit 105 in the first embodiment will be described. In this process, the sensitivity management unit 105 receives the sensitivity change information from the sensitivity change unit 104, changes and stores the operation sensitivity determined according to the focus position. In the explanation of the flowchart shown in FIG. 6, it is assumed that the focus position is 3000 and the applied operation sensitivity is the operation sensitivity A (value is 25).

First, the sensitivity management unit 105 determines whether or not the sensitivity change information has been input (S301). If the sensitivity change information has not been input, the sensitivity management unit 105 determines again whether or not the sensitivity change information has been input. On the other hand, when the sensitivity change information is input, the operation sensitivity is changed and stored according to the sensitivity change information (S302). For example, if the content of the input sensitivity change information is 0.5 times, the operation sensitivity determined by the focus position is multiplied by 0.5 to 12.5, and if the content of the sensitivity change information is double, the operation sensitivity value is set. Double it, change it to 50, and memorize it. Subsequently, the sensitivity management unit 105 transmits the stored operation sensitivity to the output generation unit 102, outputs the output (S303), and ends the process.

In this way, each time the sensitivity change information is input from the sensitivity change unit 104, the sensitivity management unit 105 changes and stores the value of the operation sensitivity. As a result, even if the operation sensitivity is set in advance so that the user can easily focus on the nearest side, the operation sensitivity can be set to the optimum operation sensitivity desired by the user by setting the operation sensitivity according to the focus position.

As described above, in the first embodiment, the relationship between the operation amount and the drive command can be changed by the changeable operation sensitivity according to the focus position, and the operation device capable of operating the lens device 20 with the operation sensitivity desired to be realized by the user is provided. Can be provided.

Next, the focus controller 30 of the second embodiment will be described with reference to FIGS. 7 to 9. FIG. 7 is a functional block diagram of the focus controller 30 of the second embodiment. Focus presets are possible with the focus controller 30 of the second embodiment. FIG. 8 is a processing flowchart for outputting a drive command by the focus preset function of the focus controller 30 in the second embodiment to the lens device 20. FIG. 9 is a processing flowchart for determining, changing, and storing the operation sensitivity according to the sensitivity change information in the focus controller 30 of the second embodiment.

First, the focus preset function will be described. The focus preset function sets a drive command in advance and sends the drive command to the lens device by operating a button. It is used to change the focus instantly by operating a button in a situation where shooting conditions such as a subject and an angle of view are predetermined. After the focus is changed, the operation member is operated to manually operate the focus according to the subject, and the value of the operation sensitivity at this time is dealt with in the second embodiment. The focus preset functions in the second embodiment are referred to as focus preset 1 and focus preset 2.

The lens device 20 to be operated by the focus controller 30 has the same configuration as that of the first embodiment. The description is omitted here. The focus controller 30 of the second embodiment has substantially the same function and configuration as the focus controller 10 of the first embodiment. Hereinafter, the configurations of different parts are designated by different reference numerals, and this part will be described here. On the other hand, in the configuration of the focus controller 30 of the second embodiment, the operation unit 101, the communication unit 103, and the sensitivity changing unit 104 have the same configuration as the focus controller 10 of the first embodiment, and thus have the same reference numerals. The explanation in is omitted.

In the configuration of the focus controller 30 of the second embodiment, the output generation unit 302 and the sensitivity management unit 305 are different from the focus controller 10 of the first embodiment. Further, the focus controller 30 of the second embodiment includes a function execution unit 306 in addition to the configuration of the focus controller 10 of the first embodiment. The communication unit 103 is connected to the function execution unit 306, outputs a focus position, and inputs a drive command. The communication unit 103 is connected to the function execution unit 306, outputs a focus position, and inputs a drive command.

The output generation unit 302 is connected to the function execution unit 306, and the execution function information and the drive command are input. When the execution function information is input, the generation of the drive command is stopped from the operation amount. When the focus position is input after the execution function information is input, it is determined whether the focus position is stopped within the range including the predetermined drive command, and if the determination is correct, the drive command is generated from the operation amount. To resume.

The sensitivity management unit 305 is connected to the function execution unit 306. Execution function information is input from the function execution unit 306 to the sensitivity management unit 305, and different operation sensitivities are output according to the execution function information. Further, when the sensitivity change information is input from the sensitivity change unit 104, the sensitivity management unit 305 determines one operation sensitivity from a plurality of operation sensitivities stored according to the execution function information. The sensitivity management unit 305 changes and stores the value of the operation sensitivity determined according to the content of the sensitivity change information. In the second embodiment, when the execution function information is the focus preset 1, the operation sensitivity D, and when the focus preset 2 is the operation sensitivity E, each has a plurality of different operation sensitivities. The function execution unit 306 determines which operation sensitivity is output or changed and stored. The initial value of any of the operation sensitivities can be arbitrarily set, and for example, 100 can be set as the initial value in advance.

The function execution unit 306 includes a focus preset 1 button and a focus preset 2 button, which are buttons (not shown). Each time the focus preset 1 button is pressed, the execution function information indicating that the focus preset 1 has been executed and the drive command of the focus preset 1 are output. Further, each time the focus preset 2 button is pressed, the execution function information indicating that the focus preset 2 has been executed and the drive command of the focus preset 2 are output.

By configuring the focus controller 30 in this way, the operation unit 101 can output the operation amount according to the amount operated by the user, as in the first embodiment. The output generation unit 302 outputs a drive command from the input focus position, operation amount, and operation sensitivity. The communication unit 103 converts the drive command into a drive command command and transmits the drive command to the lens device 20 via the communication unit 201. The lens device 20 drives the focus lens 204 based on the drive command input through the drive command command.

In addition, in the focus controller 30 of the second embodiment, when the focus preset is executed by the function execution unit 306, the execution function information and the drive command are output. The communication unit 103 converts the input drive command into a drive command command and transmits it to the lens device 20 via the communication unit 201. The lens device 20 drives the focus lens 204 based on the drive command input through the drive command command. When the execution function information is input, the output generation unit 302 stops the generation of the drive command by the operation amount from the operation unit 101. Then, it is determined whether the focus position is stopped within the range including the predetermined drive command, and if the determination is correct, the generation of the drive command by the operation amount is restarted. The sensitivity change unit 104 generates and outputs sensitivity change information each time the user operates until the current operation sensitivity becomes as expected. The sensitivity management unit 305 changes and stores the operation sensitivity from the input execution function information and sensitivity change information. As a result, the user can operate the focus lens 204 and set the desired operation sensitivity for each focus preset function to be executed.

A processing flowchart for outputting a drive command by the focus preset function of the focus controller 30 to the lens device 20 in the second embodiment will be described with reference to FIG. In this process, the function execution unit 306 executes the focus preset function, stops the generation of the drive command by the operation amount, and outputs the drive command by the focus preset function to the lens device 20. It is assumed that the drive command output by the focus preset is set to 8000 in advance.

First, the function execution unit 306 determines whether a button (not shown) for executing the focus preset function has been operated (S501). If the button is not operated, the flow is as follows. First, the sensitivity management unit 305 determines the operation sensitivity according to the focus position and outputs it to the output generation unit 302 (S502). Subsequently, the operation unit 101 detects the rotation position of the operation member (not shown) of the operation unit 101, generates an operation amount, and outputs the operation amount to the output generation unit 302 (S503). The output generation unit 302 generates a drive command value according to the operation amount and the operation sensitivity, and outputs the drive command value to the communication unit 103 (S504). The communication unit 103 converts (encodes) the input drive command value into a drive command command in a communicable communication command format, generates it as a drive command, transmits it to the lens device 20 (S505), and ends the process. ..

On the other hand, when it is determined that the button for executing the focus preset function is operated, the flow is as follows. First, the function execution unit 306 outputs a drive command to the communication unit 103, transmits the execution function information to the sensitivity management unit 305, and outputs the execution function information and the drive command to the output generation unit 302 (S506). Subsequently, the communication unit 103 encodes the input drive command into a communicable communication command format and transmits it to the lens device 20 (S507). The output generation unit 302 determines whether or not the focus position is stopped within the drive command range including the input predetermined drive command (S508). If the focus position has not stopped within the range including the input predetermined drive command, the output generation unit 302 checks again whether the focus position has stopped within the range including the input predetermined drive command. judge. When the focus position is stopped within the range including the input predetermined drive command, the sensitivity management unit 305 determines the operation sensitivity according to the execution function information and outputs it to the output generation unit 302 (S509). ). After that, the operation unit 101 performs the steps S503, S504, and S505 of detecting the rotation position of the operation member (not shown) of the operation unit 101, generating an operation amount, and outputting the operation amount to the output generation unit 302. In the focus controller 30 of the second embodiment, the range including the predetermined drive command is a range created by a value of 8000 ± 100 with respect to the drive command 8000. This is a range in which even if the lens device 20 operates in response to the drive command, the focus position does not always completely match the drive command within the range of controllability.

By generating a drive command based on the operation sensitivity and the operation amount according to the execution function information in this way, the focus preset that executes the change of the focus position of the focus lens 204 per the operation amount by changing the operation sensitivity. It can be changed for each function.

Subsequently, with reference to FIG. 9, a process of determining, changing, and storing the operation sensitivity according to the sensitivity change information in the focus controller 30 of the second embodiment will be described. In this process, the sensitivity management unit 305 inputs the sensitivity change information from the sensitivity change unit 104, determines the operation sensitivity according to the sensitivity change information, changes the operation sensitivity, and stores the information.

The sensitivity management unit 305 determines whether or not the sensitivity change information has been input (S601). If the sensitivity change information has not been input, it is determined again whether or not the sensitivity change information has been input (S601). On the other hand, when the sensitivity change information is input, the sensitivity management unit 305 subsequently determines whether the focus preset function executed from the execution function information is the focus preset 1 (S602). When it is determined that the focus preset function is the focus preset 1, the sensitivity management unit 305 determines the operation sensitivity to the operation sensitivity D (S603). Then, the operation sensitivity is changed and stored according to the sensitivity change information (S604). Here, for example, if the input sensitivity change information is -10, the sensitivity management unit 305 changes the determined operation sensitivity value to -10 to 90, and if it is +10, the operation sensitivity value is changed to +10 to 110. It is something to remember. The stored operation sensitivity is output to the output generation unit 302 (S605), and the process is terminated. On the other hand, if it is determined in step S602 that the focus preset function is not focus preset 1, the sensitivity management unit 305 determines the operation sensitivity to the operation sensitivity E (S606). Then, the above-mentioned steps S604 and S605 are subsequently executed.

In this way, each time the sensitivity change information is input from the sensitivity change unit 104, the sensitivity management unit 305 changes and stores the value of the operation sensitivity, so that the user can obtain the operation sensitivity according to the execution function information. It becomes possible to set.

As described above, in the second embodiment of the present invention, the relationship between the operation amount and the drive command can be changed by the changeable operation sensitivity according to the execution function information, and the lens device 20 is operated with the operation sensitivity desired to be realized by the user. It is possible to provide an operating device that can be used.

Next, the focus controller 50 of the third embodiment will be described with reference to FIGS. 10 to 13. FIG. 10 shows a functional block diagram of the focus controller 50 of the third embodiment. FIG. 11 is a flowchart of a process for determining the operation sensitivity based on the drive command. FIG. 12 shows a flowchart of a process of generating a drive command and outputting it to a lens based on the operation sensitivity in the operation device of the third embodiment of the present invention. FIG. 13 shows a flowchart of a process of changing and storing the operation sensitivity determined according to the drive command in the operation device of the third embodiment. The focus controller 50 of the third embodiment can also be focused preset.

The lens device 20 to be operated by the focus controller 50 has the same configuration as that of the first embodiment. The description is omitted here. The focus controller 50 of the third embodiment has substantially the same function and configuration as the focus controller 10 of the first embodiment. For example, in the configuration of the focus controller 50 of the third embodiment, the operation unit 101, the output generation unit 102, the communication unit 103, and the sensitivity changing unit 104 have the same configuration as the focus controller 10 of the first embodiment, and thus have the same reference numerals. Is added, and the description here is omitted. On the other hand, in the configuration of the focus controller 50 of the third embodiment, the sensitivity management unit 505 is different from that of the focus controller 10 of the first embodiment. Hereinafter, the configurations of different parts are designated by different reference numerals, and this part will be described here.

The output generation unit 102 is connected to the sensitivity management unit 505, inputs the operation sensitivity, and outputs a drive command. The communication unit 103 of the focus controller 50 of the third embodiment is not connected to the sensitivity management unit 505. The sensitivity management unit 505 determines one operation sensitivity from a plurality of operation sensitivities stored according to the input drive command. It also outputs the determined operation sensitivity.

Further, when the sensitivity change information is input from the sensitivity change unit 104, the sensitivity management unit 5050 changes and stores the operation sensitivity determined according to the drive command according to the content of the sensitivity change information. The focus controller 50 of the third embodiment can be configured so that the operation sensitivity conditions and the operation sensitivities determined in response to the drive command can be selected from preset ones. For example, when the operation sensitivity condition and the operation sensitivity determined according to the drive command are "0 or more and 3333 or less", the operation sensitivity A is applied. When the operation sensitivity condition and the operation sensitivity determined according to the drive command are "3334 or more and 6666 or less", the operation sensitivity B is applied. When the operation sensitivity condition and the operation sensitivity determined according to the drive command are "6667 or more and 10000 or less", the operation sensitivity C is applied. Each has a different value of operation sensitivity, and it is determined which operation sensitivity is output or changed and stored according to the drive command. For example, 100 for the operation sensitivity A, 50 for the operation sensitivity B, and 25 for the operation sensitivity C are set in advance as the values of the operation sensitivity. The values preset for these operating sensitivities can be selected as arbitrary values according to the characteristics of the lens device 20. This is set because the depth of focus is shallower on the near side than on the infinite side, and the ease of focusing is improved by allowing a larger amount of operation to be used for focusing.

With this configuration, the operation unit 101 outputs the operation amount according to the amount operated by the user. The output generation unit 102 outputs a drive command from the input focus position, operation amount, and operation sensitivity. The communication unit 103 converts the drive command into a drive command command and transmits the drive command to the lens device 20 via the communication unit 201. The lens device 20 drives the focus lens 204 based on the drive command input via the drive command command. Further, the sensitivity change unit 104 generates and outputs sensitivity change information each time the user operates until the current operation sensitivity becomes as expected. The sensitivity management unit 505 changes and stores the operation sensitivity from the input drive command and sensitivity change information. As a result, the user can set the desired operation sensitivity for each drive command while operating the focus lens 204.

Subsequently, with reference to FIG. 11, the processing of the sensitivity management unit 505 of the focus controller 50 of the third embodiment will be described. In this process, the sensitivity management unit 505 of the focus controller 50 determines the operation sensitivity based on the drive command.

First, the sensitivity management unit 505 determines whether or not a drive command has been input (S701). If the drive command has not been input, the sensitivity management unit 505 determines again whether or not the drive command has been input. On the other hand, when it is determined that the drive command has been input, the sensitivity management unit 505 determines whether the drive command is 0 or more and 3333 or less (S702). When it is determined that the drive command is 0 or more and 3333 or less, the sensitivity management unit 505 determines the operation sensitivity to the operation sensitivity A (S703), and ends the process. When the sensitivity management unit 505 determines that the drive command is not 0 or more and 3333 or less, it further determines whether or not the drive command is 3334 or more and 6666 or less (S704). When it is determined that the drive command is 3334 or more and 6666 or less, the sensitivity management unit 505 determines the operation sensitivity to the operation sensitivity B (S705), and ends the process. On the other hand, when it is determined that the drive command is not 3334 or more and 6666 or less, the sensitivity management unit 505 determines the operation sensitivity to the operation sensitivity C (S706), and ends the process.

In this way, the drive command can be generated based on the operation sensitivity and the operation amount according to the drive command. By changing the operation sensitivity, the change in the focus position of the focus lens 204 per the amount of operation can be changed for each drive command.

Subsequently, with reference to FIG. 12, the process of generating a drive command and outputting it to the lens device 20 in the focus controller 50 in the third embodiment will be described. In this process, the user generates an operation amount according to a change in the rotation position due to the knob operation of the operation unit 101, generates a drive command based on the operation sensitivity, and outputs the drive command to the lens device 20.

First, the sensitivity management unit 505 determines the operation sensitivity based on the drive command and outputs it to the output generation unit 102 (S801). Subsequently, the operation unit 101 detects a change in the rotational position of the operation member (not shown) of the operation unit 101, generates an operation amount (S802), and outputs the operation amount to the output generation unit 102. Then, the output generation unit 102 generates a drive command value obtained according to the operation amount and the operation sensitivity, and outputs the drive command value to the communication unit 103 (S803). The communication unit 103 converts (encodes) the input drive command value into a drive command command in a communicable communication command format, transmits it to the lens device 20 (S804), and ends the process. In this way, the drive command can be generated based on the operation sensitivity and the operation amount according to the drive command. According to this, by changing the operation sensitivity, it is possible to change the change in the focus position of the focus lens 204 per the amount of operation for each drive command.

With reference to FIG. 13, in the focus controller 50 of the third embodiment, a process of changing and storing the operation sensitivity of the sensitivity management unit 505 will be described. This process is a process in which the sensitivity management unit 505 inputs sensitivity change information from the sensitivity change unit 104, changes and stores the operation sensitivity determined according to the drive command. In the description of this flowchart, it is assumed that the drive command is 3000 and the applied operation sensitivity is the operation sensitivity A (value is 25).

The sensitivity management unit 505 determines whether or not the sensitivity change information has been input (S901). If it is determined that the sensitivity change information has not been input, it is determined again whether or not the sensitivity change information has been input. On the other hand, when it is determined that the sensitivity change information has been input, the sensitivity management unit 105 changes and records the operation sensitivity according to the sensitivity change information. For example, if the content of the input sensitivity change information is 0.5 times, the value of the operation sensitivity determined by the drive command is multiplied by 0.5 to obtain 12.5. If the content of the sensitivity change information is doubled, the value of the operation sensitivity is doubled, changed as 50, and stored. Subsequently, the stored operation sensitivity is output to the output generation unit 102 (S903), and the process is terminated.

In this way, the sensitivity management unit 505 changes and stores the operation sensitivity value each time the sensitivity change information is input from the sensitivity change unit 104, that is, each time the sensitivity is changed. This allows the user to set the operation sensitivity according to the drive command.

As described above, in the focus controller 50 of the third embodiment according to the present invention, the relationship between the operation amount and the drive command can be changed by the changeable operation sensitivity according to the drive command, and the lens device has the operation sensitivity desired to be realized by the user. An operating device capable of operating 20 can be provided.

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 modifications can be made within the scope of the gist thereof. For example, there is an autofocus function (AF function) as an example of changing the operation sensitivity according to the execution of another function other than the focus preset. After executing autofocus by calculating the defocus amount of a specific subject and replacing the operation sensitivity after focusing on the specific subject with the execution of the focus preset function and the execution of the AF function of the second embodiment. The operation sensitivity of can be changed.
