Description

  The present invention relates to an operating device, a lens device, and an imaging device.

  In a lens apparatus in an imaging apparatus such as a television camera, the movable optical member is controlled by a control system including a drive unit such as a motor. For focus adjustment by moving a lens included in the lens device, a focus operation device is used to give a command to the control system. The focus operation device, for example, can rotate its operation member (knob) and outputs a command corresponding to the operation amount. When the command and the moving amount of the lens are in a proportional relationship, it is difficult to perform focus adjustment (focusing) by operating the operation member under a condition where the depth of field is shallow. Here, as shown in FIG. 10, it is known to be able to select such a characteristic that the change of the object distance becomes gentle on the near side or infinity side with respect to the unit operation amount of the operation member (patent) Reference 1).

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a system block diagram of focus control according to the lens apparatus of the first embodiment. Reference numeral 10 denotes a focus controller (operation device) 10 for remotely operating the lens device 20, and constitutes a lens system together with the lens device 20. Reference numeral 30 denotes a camera device having an image pickup element 31 that receives an image formed by the lens device 20, and constitutes an image pickup device together with the lens system. Reference numeral 101 denotes an operation unit for operating a focus by a cameraman, which is a so-called end knob (operation member) 101 in which an operable range is limited by a mechanical movable end. That is, the operation unit has a member that defines the end of the operation range. The knob position detection unit 102 is a position sensor such as a potentiometer or a rotary encoder, and outputs a position signal proportional to the operation amount of the knob 101 with an end. A focus command position (command value) 103 is calculated by an input from the knob position detection unit 102. The communication unit 104 encodes the focus command position calculated by the focus command position calculation unit 103 into a communication command format and transmits it to the communication unit 201 of the lens device 20.

  The communication unit 201 is configured in the lens device 20 and exchanges commands with the communication unit 104 of the focus controller 10. Upon receiving the command for the focus command position, the communication unit 201 decodes the received data and sends it to the focus drive position calculation unit (processing unit) 202. The focus drive position calculation unit 202 calculates the focus drive position from the command position from the focus controller 10 and the assignment data in the assignment storage unit (storage unit) 206 and sends the focus drive position to the focus control unit 203. The allocation data in the allocation storage unit 206 will be described later. The focus control unit 203 generates a drive signal for driving and controlling the focus lens 204 to the drive position. Reference numeral 205 denotes a position sensor that detects the position of the focus lens 204. The detected position signal is input to the focus control unit 203, and feedback control is performed by the focus control unit 203.

  Since the focus controller 10 is used for general purposes, it is normalized within the movable range of the knob 101 with the end so that the position of the entire driving range of the focus lens 204 can be commanded without depending on the model of the lens device 20. The commanded position is transmitted to the lens device 20. The normalized command position is a numerical value lower than the resolution of the knob position detection unit 102. In this embodiment, the normalized command position is assumed to be a normalized command position of 0 to 10,000. The focus controller 10 transmits a command position of 0 to 10000 regardless of the model of the lens device 20 connected by the communication unit 104.

  The conventional lens device 20 assigns all the driving positions of the focus lens 204 to command positions of 0 to 10,000 and calculates the driving position. For example, the command position 0 is set to the closest end (MOD) of the focus lens 204. ), The command position 10000 was set to the infinite end (INF). However, since the resolution of the position command is fixed regardless of the model of the lens device 20, even if the resolution of the driving position of the lens device 20 is high, the resolution is limited by the resolution of the position command. Therefore, it is impossible to perform focus adjustment using the conventional focus controller 10 in a lens apparatus that has a sensitive focus operation sensitivity and requires a resolution higher than 10,000.

  Thus, in this embodiment, the drive position of the focus lens 204 is divided into two regions, and command positions of 0 to 10000 are assigned to the respective regions, thereby realizing high resolution using the conventional focus controller 10. .

  FIG. 2 is a diagram illustrating information on the relationship between the focus command position and the drive position in the first embodiment. The abscissa indicates the command position from the focus controller 10 and indicates a value of 0 to 10000. The ordinate indicates the drive position range (operation range) of the focus lens 204. In this embodiment, the drive position has a higher resolution than the command position. As an example of the lens device 20, a value of 0 to 20000 is shown. 0 is the closest end (MOD) and 20000 is the infinite end (INF). The relationship between the conventional command position and the drive position is indicated by a dotted line, and the relationship between the command position and the drive position in the present embodiment is indicated by a solid line.

  Conventionally, as shown in the figure, since the entire drive position is assigned to the entire position command, driving from the focus controller 10 can only be performed with a resolution of 10,000. In this embodiment, as shown in the figure, the drive position area is divided into two areas, area A and area B, with the branch position a as a boundary, and command positions of 0 to 10,000 are assigned to each area. Yes. The allocation storage unit 206 holds the graph indicated by the solid line in FIG. 2 as allocation data such as a pickup table or a relational expression, and can calculate the drive position relative to the command position for each region.

FIG. 3 is a flowchart of the focus drive position calculation process in the first embodiment.
When the power of the lens apparatus 20 is turned on, the focus position is acquired from the focus position detection unit 205 in step S101.

  In step S102, the area where the current focus lens is located is set valid from the assignment data in the assignment storage unit 206. In this embodiment, the region A is valid if the focus lens position is 0 to 10,000, and the region B is valid if the focus lens position is 10001 to 20000. As described above, the initial process such as when the power is turned on makes the drive for the first command position minimum by making the current focus lens area effective. However, the present invention is not limited to this, and an arbitrary area may be validated.

  In step S103, the command position from the focus controller 10 is received, and the process proceeds to step S104.

  In step S104, it is determined whether or not the current command position has reached the branch position a from the previous command position that is not the branch position a. If the branch position a has been reached at the current command position, the process proceeds to step S105. If the branch position a has not been reached, or if the branch position a continues to be reached, the process proceeds to step S106.

  In step S105, the effective area is changed. When the area A is valid, the area B is validated, and when the area B is valid, the area A is validated.

  In step S <b> 106, the drive position is calculated from the currently effective area and the command position, and the focus lens 204 is driven to the drive position via the focus control unit 203. For example, when the region B is valid and the command position is 5000, the drive position is 15000. Next, the process returns to step S103, and steps S103 to S106 are repeated.

  As described above, the operating device for operating the movable optical member of the present invention includes the operating member, the operation amount of the operating member set for each of a plurality of ranges of the operating range of the optical member, and the optical And a processing unit that generates a command related to an operation amount of the optical member based on information on a relationship with an operation amount of the member and information on an effective range of the plurality of ranges. . More specifically, the drive area of the focus lens 204 is divided into two areas, each assigned a command position, and the effective area is changed at the branch position a, thereby doubling the resolution of the command position over the entire area. The drive position can be commanded with a resolution of. Therefore, it is effective when the position resolution of the lens device 20 is higher than the resolution of the focus controller 10, and finer focus adjustment is possible, and focus operability can be improved.

  In this embodiment, the focus has been described. However, the present invention is not limited to this, and may be a movable optical member such as a zoom or an iris.

  In the present embodiment, the controller for the knob with the end has been described. However, the controller for the knob without the end may be used.

  In this embodiment, an example in which the drive position is divided into two regions has been described. However, the present invention is not limited to this, and the drive position may be divided into two or more regions. In addition, although the branch position a is the center position of the drive region, it may be an arbitrary position. Furthermore, the relationship in which the assignment of the command position to each area is continued (turned back) at the branch position a has been described, but is not limited thereto. For example, similarly to the region A, the region B may have a relationship in which the command position 0 is the drive position 10000 and the command position 10000 is the drive position 20000. By doing so, the focus lens 204 is driven to the drive end when changing the effective area, but the rotation direction of the knob 101 with the end and the drive direction of the focus lens can always coincide. Furthermore, the example in which the position command and the drive position are in a proportional relationship in each region has been described. However, the present invention is not limited to this, and may be a relationship in a curved characteristic such as an exponential function, for example.

Hereinafter, with reference to FIGS. 4-6, the lens apparatus by Example 2 of this invention is demonstrated.
FIG. 4 is a system block diagram of focus control according to the second embodiment. Components similar to those described in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

  Reference numeral 105 denotes an operation unit for a cameraman to operate the focus, which is a so-called endless knob 105 having no mechanical movable end. In the same manner as the endless knob 101 described in the first embodiment, the focus controller 10 having such an endless knob 105 is capable of commanding the position of the entire driving range of the focus lens 204. The position command normalized within the predetermined operation angle is output. In this embodiment, a description will be given assuming that a normalized position command of 0 to 10,000 is output at an operation angle of 1000 degrees. Since the endless knob 105 has no movable end, it can be operated over an operating angle of 1000 degrees. In this case, the command position is determined by the minimum value (0) or the maximum value (10000) of the normalized command position. To maintain. When the endless knob 105 is operated in the reverse direction while the command position is maintained, a command position that immediately increases from the minimum value or decreases from the maximum value is output. The focus controller 10 transmits a command position of 0 to 10000 regardless of the model of the lens device 20 connected by the communication unit 104.

  When receiving a matching instruction from the lens device 20 via the communication unit 104, the position command matching unit 106 changes the current position command to the position instructed by the lens device 20. In the case of the focus controller 10 having the endless knob 105, the absolute command position corresponding to the operation position of the endless knob 105 is not determined when the power is turned on, so the command position is not uniquely determined. Therefore, when the power is turned on, the lens device 20 instructs the focus controller 10 to output a command position that matches the current position of the focus lens 204. Therefore, it is possible to prevent the focus lens 204 from being unintentionally driven when the power is turned on, and to operate the focus from the current position of the focus lens 204.

  When the effective area is changed by the focus drive position calculation unit 202, the alignment instruction unit 207 is configured to change the command position to the current position of the focus lens 204 in the new effective area via the communication unit 201. 10 is instructed.

  FIG. 5 is a diagram illustrating the relationship between the focus command position and the drive position in the second embodiment. The abscissa indicates the command position from the focus controller 10 and indicates a value of 0 to 10000, and the ordinate indicates the drive position range of the focus lens 204. In this embodiment, the lens device 20 having a drive position with higher resolution than the command position. As an example, a value of 0 to 20000 is shown. 0 is the closest end (MOD) and 20000 is the infinite end (INF). The relationship between the command position and the drive position in this embodiment is shown by a solid line. In the present embodiment, as shown in the drawing, the entire region of the drive position is covered and a partial region by the region C of 0 to 11000 (branch position cd) and the region D of 9000 (branch position dc) to 20000. Two areas where (ends) overlap each other are set, and command positions of 0 to 10000 are assigned to the respective areas. The allocation storage unit 206 holds the graph indicated by the solid line in FIG. 5 as allocation data such as a pickup table or a relational expression, and can calculate the drive position relative to the command position for each region.

FIG. 6 is a flowchart of focus drive position calculation processing in the second embodiment.
When the power of the lens device 20 is turned on, the focus position is acquired from the focus position detection unit 205 in step S201.

  In step S202, the area where the current focus lens 204 is located is set valid from the assignment data in the assignment storage unit 206. In this embodiment, the region C is valid if the focus lens position is 0 to 8999, and the region D is valid if the focus lens position is 11001 to 20000. In the case of the region (9000 to 11000) where the region C and the region D overlap, an arbitrary region may be valid.

  In step S203, a command position corresponding to the position of the current focus lens 204 in the effective area is obtained from the allocation storage unit 206, and alignment is instructed to the focus controller 10 so as to output the command position. As described above, the initial processing such as when the power is turned on is such that the command position corresponding to the current position of the focus lens 204 is output to the focus controller 10 so that the first command position is not driven and the current position is The operation can be started from the position of the focus lens 204.

  In step S204, the command position from the focus controller 10 is received, and the process proceeds to step S205.

  In step S205, the drive position is calculated from the currently effective area and the command position, and the focus lens 204 is driven to the drive position via the focus control unit 203. For example, when the region D is valid and the command position is 1000, the drive position is set to 11000.

  In step S206, it is determined whether or not the currently valid area is area C. If it is area C, the process proceeds to step S207, and if it is not area C, that is, if it is area D, the process proceeds to step S210.

In step S207, it is determined whether or not the current command position has reached the branch position cd from the previous command position that is not the branch position cd. If the branch position cd has been reached at the current command position, the process proceeds to step S208. If the branch position cd has not been reached, the process returns to step S204.
In step S208, the effective area is changed from area C to area D.

  In step S209, a command position corresponding to the drive position calculated in step S205 in area D is obtained from the assignment data in the assignment storage unit 206, and alignment is instructed to the focus controller 10 so as to output the command position. That is, the focus drive position calculation unit 202 instructs the focus controller 10 to output a command position corresponding to the effective area after switching when the effective area is switched. In the example of FIG. 5, when reaching the command position of 10000, alignment is instructed to change to the command position of 1000. Next, the process returns to step S204.

In step S210 when the region D is valid, it is determined whether or not the current command position has reached the branch position dc from the previous command position that is not the branch position dc. If the branch position dc has been reached at the current command position, the process proceeds to step S211. If the branch position dc has not been reached, the process returns to step S204.
In step S211, the valid area is changed from area D to area C.

  In step S212, a command position corresponding to the drive position calculated in step S205 in region C is obtained from the allocation data in the allocation storage unit 206, and alignment is instructed to the focus controller 10 so as to output the command position. In the example of FIG. 5, when the command position of 0 is reached, alignment is instructed to change to the command position of 9000. Next, it returns to step S204 and repeats step S204 to step S212.

  That is, the focus drive position calculation unit 202 has a threshold value on the side closer to the end (11000) of the effective area (for example, the area C) in the overlapping area of the two branch positions (two threshold values). When (branch position cd) is reached, the effective area is switched from the area (area C) to the other area (area D) constituting the overlapping area. That is, there are a plurality of threshold values, and the processing unit selects a threshold value for switching the effective range based on the effective area before switching.

  As described above, two areas are set as the driving area of the focus lens 204 so that the entire range of the driving position is covered and some of the adjacent areas overlap each other, and a command position is assigned to each area. Thus, the drive position can be commanded with a resolution higher than the resolution of the position command. Further, by changing the effective area and instructing the focus controller 10 to perform command position change alignment, the endless knob 105 can be operated continuously in the same direction. Furthermore, by dividing the area by overlapping some areas, it is possible to change the area even if it is reversed at the branch position of the area change, and the focus operability can be further improved. it can.

  Further, in the present embodiment, the example in which the partial overlap area is set to 0 to 1000 and 9000 to 10000 in the command position has been described. However, the present invention is not limited to this, and two or more overlap areas with the minimum resolution of the position command. If there is.

  In this embodiment, an example in which the effective area is changed when the branch position is reached has been described. However, the present invention is not limited to this, and a branch area having a predetermined width is set and a command is sent to the branch area. If a value is entered, the effective area may be changed.

  In this embodiment, an example in which alignment is instructed at the command position corresponding to the branch position when changing the area has been described. However, a command position instructing alignment may be obtained according to the change speed of the command position. good. For example, when the change speed of the command position is 100 every cycle and the branch position is reached, it is estimated that the next command position will also advance by 100, and a command obtained by adding 100 to the command position corresponding to the branch position in the effective region The alignment may be instructed by the position. That is, the focus drive position calculation unit 202 has an effective area (for example, an area where the estimated command position after a predetermined time based on the change history of the command position is an overlapping area of the two branch positions (two thresholds) (for example, , The effective region may be switched from region C to region D when the threshold value (branch position cd) near the end (11000) of region C) is reached.

Hereinafter, with reference to FIGS. 7-9, the lens apparatus by Example 3 of this invention is demonstrated.
FIG. 7 is a system block diagram of focus control according to the third embodiment. Components similar to those described in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

  A mode change instruction unit (switching unit) 208 receives an instruction from the user by a switch or the like, and switches a plurality of modes in which the relationship between the command position and the drive position is different. In this embodiment, the mode 1 is a mode in which the entire drive position is assigned to the command position as in the prior art, and the entire drive position is divided into a plurality of areas, and the operation of the drive position with higher resolution than in the mode 1 is performed. An example having a control mode of mode 2 that is a mode to be enabled will be described. In the operating device according to the third embodiment, the mode is switched between a plurality of modes having a different number of regions in a plurality of regions, or between a plurality of modes including a mode in which the operation range is composed of only a single range. The mode is switched by.

  The assignment generation unit (area setting unit) 209 generates assignment data indicating the relationship between the command position and the drive position according to the current position of the focus lens 204 when mode 2 is instructed.

  FIG. 8 is a diagram illustrating the relationship between the focus command position and the drive position in each mode according to the third embodiment. FIG. 8A shows the relationship in mode 1, and FIG. 8B shows the relationship between the command position and the drive position generated when changing to mode 2. FIG. 8B shows an example in which the mode is changed to mode 2 when the current command position is 5000 in mode 1. The abscissa indicates the command position from the focus controller 10 and indicates a value of 0 to 10000, and the ordinate indicates the drive position range of the focus lens 204. In this embodiment, the lens device 20 having a drive position with higher resolution than the command position. As an example, the value of 0-40000 is shown. 0 is the closest end (MOD) and 40000 is the infinite end (INF). A method for generating assignment data indicating the relationship between the command position and the drive position in mode 2 when the mode is changed will be described.

  In mode 1, the current command position from the focus controller 10 is 5000 (drive position is 20000). When the mode is changed to mode 2 at this time, the resolution (graph inclination) higher than that of mode 1 set in advance is set. The resolution in mode 2 may be determined by the resolution of the driving position of the lens device 20 and optical conditions such as the depth of field. For example, when the resolution at which the drive position advances by 1 with respect to the command position advances by 1 or the minimum depth of field of the lens device 20 corresponds to 2 of the drive position, the drive position changes by 1 while the command position advances by 1. 2 resolution is assumed. Mode 2f is assigned so as to pass through the point of command position 5000 and drive position 20000 with the resolution (gradient of the graph).

  Next, mode 2e is assigned so as to pass through the points of command position 0 and drive position 0 with the same inclination. Furthermore, mode 2g is assigned so as to pass through the points of command position 10000 and drive position 40000 with the same inclination. In this manner, the area can be divided into three areas: area E allocated by mode 2e, area F allocated by mode 2f, and area G allocated by mode 2g. Further, the branch position fe (second threshold value), the branch position ef (first threshold value), and the branch position gf (first threshold value) which are trigger positions for changing an effective area within the overlapping areas of the areas. (2 threshold value) and branch position fg (first threshold value) are set, and allocation data of the command position and the drive position is generated. The allocation data generated by the allocation generation unit 209 in this way is stored in the allocation storage unit 206.

FIG. 9 is a flowchart of the mode change process in the third embodiment.
First, in step S301, the mode change instruction unit 208 determines whether or not there is a mode change instruction from the user. If there is an instruction to change the mode, the process proceeds to step S302. If there is no instruction to change the mode, step S301 is maintained.

  In step S302, it is determined whether or not the mode change is from mode 1 to mode 2. If the mode is changed from mode 1 to mode 2, the process proceeds to step S303. If the mode is changed from mode 2 to mode 1, the process proceeds to step S305.

  In step S303, as described with reference to FIG. 8, in accordance with the current command position of the focus controller 10, command position / drive position allocation data is generated so that there is no change in the drive position. move on.

  In step S304, the allocation data generated in step S303 is validated as driving position calculation data.

  In step S305, which proceeds from step S302 in the case of mode 2 to mode 1, the allocation data of mode 1 held in advance is validated as drive position calculation data.

  As described above, when the mode 1 is changed to the mode 2, the command position and the drive position are assigned so that the current command position is not changed. Operation becomes possible. Therefore, for example, when adjusting the approximate focus position in mode 1 with a low resolution, and switching to mode 2 near the in-focus subject and performing a fine adjustment in mode 2 with a high resolution, the delay caused by performing the alignment process. Thus, the mode can be changed without reducing the responsiveness of the operation.

  Further, in this embodiment, the example in which the allocation data is generated only when the mode 1 is changed to the mode 2 has been described. However, the present invention is not limited to this, and similar processing is performed when the mode 2 is changed to the mode 1. May be implemented. Furthermore, in this embodiment, an example in which the entire drive position is assigned in mode 1 has been described, but a plurality of modes with different resolutions may be switched.

  In the above example, in order to facilitate the explanation of the invention, the mode 2e is set to pass the point of the command position 0 and the drive position 0 with the inclination of the mode 2f, and the mode 2g is set to the command position 10000 with the inclination of the mode 2f. In the above description, the driving position is set so as to pass through the point of 40000. However, the present invention is not limited to the method for setting the modes 2e and 2g. For example, consider the case where the current command position from the focus controller 10 is 5000 (drive position is 20000) in mode 1 and the mode is changed to mode 2 at this time. The mode is changed to the mode 2 having a higher resolution (gradient of the graph) than the predetermined mode 1, and the mode 2f is assigned so as to pass the point of the command position 5000 and the drive position 20000 with the resolution. Next, in mode 2f, mode 2e (region E) is represented by a straight line having a slope of mode 2f passing through the point of command position 10000, which is a drive position larger by a predetermined amount (predetermined overlap amount) than the drive position at the minimum command position 0 in mode 2f Set. Further, mode 2g (region G) is set by a drive position that is smaller by a predetermined amount (predetermined overlap amount) from the drive position at the maximum command position 10000 in mode 2f and a straight line of the slope of mode 2f that passes through the point of command position 0. To do. As described above, the mode 2e (region E) and the mode 2g (region G) can be set based on the mode 2f. In this case, there is not always a mode straight line that passes through the command position 0, the drive position 0 point, and the command position 10000, the drive position 40000 point, but the drive position ranges of the adjacent modes overlap. What is necessary is just to comprise so that it may have an area | region.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
