With the above configuration, the fourth group column 4 is moved in the optical axis direction by the drive of the focus drive motor 12 to perform focusing. At this time, the reset origin position of the second group barrel 2 is defined by the focus sensor 7 attached to the rear barrel 6.

  The second group barrel 2 holds the second lens group 32, and the zoom slack 10 and the zoom rack spring 16 are attached thereto. The sleeve portion 2b and the U-groove portion 2c are guided by the first guide bar 17 and the second guide bar 27 and are restricted from moving in directions other than the optical axis, and are driven by the zoom drive motor 9 to move in the optical axis direction.

The zoom sensor 11 is a sensor that detects the reset origin position of the second group barrel 2, determines the amount of movement of the second group barrel 2 based on this signal, and zooms by moving the second group barrel 2.

  FIG. 3 is a cam lift diagram of the lens barrel of the imaging apparatus 1000 of the present embodiment. 3A is an overall view, and FIG. 3B is an enlarged view of the vicinity of TELE infinity. In FIG. 3, the horizontal axis indicates the position of the second group barrel 2 that is the zoom lens group, and the vertical axis indicates the position of the fourth group barrel 4 that is the focus lens group. 105 is the WIDE position, 106 is the TELE position, the upper side of the vertical axis is the closest side, and the lower side is the infinite side. Each position can be obtained based on the reset origin position detected using the focus sensor 7 or the zoom sensor 11.

  Reference numeral 107 denotes a cam lift curve for adjusting the focus on a subject existing at an infinite distance. Focusing is performed when an infinite subject is photographed by driving the second group barrel 2 and the fourth group barrel 4 along the cam lift curve. Can be maintained.

  The reset origin position of the second group barrel 2 and the fourth group barrel 4 is defined by the zoom sensor 11 and the focus sensor 7. Control is performed by open control or the like that calculates control information including the current position with reference to the reset origin position by counting the number of drive steps applied to the focus drive motor 12 or the zoom drive motor 19.

  In FIG. 3B, focusing is performed when the second group barrel 2 is located at the position 104 and when the fourth group barrel 4 is located at the position 102. When the second group barrel 2 is moved to the position 103 due to the influence of the looseness or the like, the focused state cannot be obtained unless the fourth group barrel 4 is located at the position 101. Since the position of the second group lens barrel 2 is controlled by open control, for example, movement due to looseness cannot be detected.

  Accordingly, when the second group barrel 2 is controlled to be positioned at the position 104 and moved to the position 103 due to the backlash or the like, the difference between the position 102 and the position 101 is determined as the position of the fourth group barrel 4. As a result, a focus shift occurs corresponding to.

  When the positions of the second group lens barrel 2 and the fourth group lens barrel 4 deviate from the cam lift curve, the second group lens barrel 2 and the fourth group lens barrel 4 deviate from the best focus state. If it is out of the best focus state, the blur may be so large as to obstruct the recognition of the subject.

  Here, each lens group is held by a shaft, a rack, or the like, but has a mounting backlash in order to reduce friction during movement and to improve assembly. The urging force is changed by a spring or the like, but the urging force changes depending on the direction in which the weight of the lens barrel is applied. For this reason, this backlash may cause the lens group to deviate from the cam lift curve during the control of each lens group.

  On the other hand, since it is necessary to eliminate the backlash between the moving lens group and the holding member in order to prevent the backlash caused by the posture change, a complicated structure or a large structure is required, resulting in an increase in the size and cost of the apparatus.

  In particular, in a zoom lens barrel that performs zooming and focusing by driving a plurality of lens groups in the optical axis direction as in this embodiment, a change in position of the plurality of lens groups affects a change in focus position. Furthermore, in recent years, zoom magnification has been increased and the size of the apparatus has been reduced, and the position sensitivity of the lens group has been increasing. When the sensitivity to the position of the lens group increases, the position change of the lens group greatly affects the focus position. For this reason, there is a high possibility that a focus shift that can be recognized by an image will occur even if the position of the lens group is very small.

  Further, since the position change of each lens group is caused by the action of gravity, the backlash state differs depending on the moving direction even if the posture is the same. For example, even if the direction of the lens barrel is horizontal, the moving lens group position may be different between the horizontal direction facing from the upward direction and the horizontal direction facing from the downward direction. In general, the horizontal direction from the upward direction tends to be close to the upward state due to the influence of inertia, and the horizontal direction from the downward direction tends to be close to the downward state.

  Specifically, the position of each lens group is different when the posture of the lens barrel is changed in the tilt direction and the tilted state is inclined 45 ° downward from the upward state, and when it is tilted 45 ° downward from the downward state. That is, the focus position may be different in each state.

  Further, the focus position may be different because the inertia applied to the moving lens group, the frictional state between the members, and the like differ depending on the speed, acceleration, and drive start position of the posture change. In the case of a surveillance camera or the like, if the posture changes after being held for a long time in a constant posture state, the friction state between the conventional member and the member may be different. Such a condition may also be included in the driving condition.

  The imaging apparatus 1000 according to the present embodiment corrects the lens group position in consideration of the posture at the start of posture change, the speed or acceleration at the time of change, in addition to the posture of the lens barrel portion described above.

In addition, the control circuit 90 comprehensively controls each component of the imaging apparatus 1000. Then, the control circuit 90 executes a program stored in a memory 91 or the like which will be described later.

Focus on it. A captured image that has been zoomed and focused by driving the zoom lens group 72 and the focus lens group 76 enters the image sensor 80. Then, the signal output from the image sensor is subjected to predetermined image processing by the image processing unit 81, taken into the control circuit 90 as image data, and stored in the memory 91.

The pan motor 87 performs pan driving of the tilt unit 82 holding the lens unit 100, and the pan origin position is defined by the pan reset sensor 89. The pan motor control unit 88 controls drive conditions such as the drive amount and drive speed of the pan motor 87. The pan motor control unit 88 is controlled by the control circuit 90.

  The gravity sensor 93 detects the installation state or posture of the camera. Note that the user may be able to set from the outside using an operation of the operation unit 92 or an operation of receiving a command by the I / F unit 94. In this case, the setting is held in the memory 91 or the like. In the present embodiment, the gravity sensor 93 corresponds to an example of an installation detection unit that detects an installation state.

  For example, when the user operates the operation unit 92, an operation signal is input to the control circuit 90, and the control circuit 90 calculates movement conditions or drive conditions for the zoom motor 19, the focus motor 12, the tilt motor 83, and the pan motor 87. And a drive signal is input into each control part, and a motor drive is performed.

  The motor drive control of the image pickup apparatus 1000 of the present embodiment will be described using the flowchart of FIG. Note that the processing of this flowchart is executed by the control circuit 90.

  When the process is started, in step S111, the control circuit 90 detects the installation state of the imaging device 1000 based on the detection signal of the gravity sensor 93. Specifically, it detects the installation state and posture such as hanging from the ceiling, standing, and wall hanging. In addition, the control circuit 90 detects the attitude of the imaging apparatus 1000 based on the detection signal of the gravity sensor 93, control information, and the like. Specifically, the pan angle, tilt angle, zoom position, focus position, and the like are detected. These detection results are stored in the memory 91 or the like. Then, the process proceeds to step S112.

  In step S <b> 112, the control circuit 90 performs an operation of waiting for an input of a control command from the user according to an operation of the operation unit 92 or a command received by the I / F unit 94. Specifically, it waits until a control command including a moving condition or a driving condition for changing a pan angle, a tilt angle, a zoom position, a focus position, and the like is input. If a control command has been input, the process proceeds to step S113.

  In step S113, when the control circuit 90 executes the control command input in step S112 based on the installation state and orientation of the imaging apparatus 1000 detected in step S111, whether the movement condition needs to be corrected or not. Determine whether. Specifically, how the orientation changes with respect to the gravitational direction when the orientation of the lens unit 100 is changed under the driving conditions included in the control command from the installation state and orientation information obtained in step S111. Judge whether to do. As an example, in step S111, the installation state is detected as being suspended from the ceiling, and the tilt unit 82 is controlled to tilt the lens unit 100 from the downward (90 °) drive start position to the horizontal (0 °) stop position. Suppose that you want to operate the system. At this time, when driving the focus lens group 4, the control circuit 90 determines that it is necessary to calculate a movement condition for correcting the stop position of the focus lens group 4 from the movement condition included in the control command. This is because in the case of ceiling suspension, the direction of gravity with respect to the posture of the lens unit 100 changes during tilt driving, and the state in which the play of the focus lens group 4 occurs changes. On the other hand, it is assumed that the pan unit 86 is controlled and the lens unit 100 is operated in the pan direction within a predetermined range. At this time, when driving the focus lens group 4, the control circuit 90 determines that it is not necessary to calculate a movement condition for correcting the position of the focus lens group 4 from the drive condition included in the control command. This is because the direction of gravity relative to the posture of the lens unit 100 does not change during pan driving in the case of ceiling suspension. Note that the conditions used for calculation include the installation state of the imaging apparatus 1000, the attitude of the lens unit 100, the driving direction, the driving amount, the driving speed, the driving acceleration, and the like. If it is determined that the movement condition needs to be corrected, the process proceeds to step S114. If it is determined that the movement condition is not necessary, the process proceeds to step S115.

  In step S114, the control circuit 90 calculates movement conditions or drive conditions for correcting the zoom motor 73, the focus motor 77, the tilt motor 83, the pan motor 87, and the like based on the determination result in step S113. Here, in the present embodiment, the driving conditions include a driving direction, a driving amount, a driving speed, a driving acceleration, and the like. The imaging apparatus 1000 in the present embodiment holds each condition for calculating the movement condition in the memory 91 or the like. Specifically, a correction amount suitable for the installation state of the imaging apparatus 1000, the attitude of the lens unit 100, the driving direction, the driving amount, the driving speed, the driving acceleration, and the like is held in the memory 91 and is input by the user input in step S112. Analyzes the contents of the control command and reads the corresponding correction amount. And a movement condition etc. are correct | amended based on the drive condition contained in the control command from a user. The correction amount to be read may hold a correction amount corresponding to each moving condition or driving condition of the zoom motor 73, the focus motor 77, the tilt motor 83, and the pan motor 87, or only a part thereof. May be held. Further, in the present embodiment, the operation using the correction amount held in the memory 91 is exemplified, but the calculation may be performed using a predetermined formula.

  In step S115, the control circuit 90 executes control for changing the pan angle, tilt angle, zoom position, focus position, and the like under a predetermined movement condition or drive condition. Each condition at this time is determined based on the movement condition or driving condition included in the control command input in step S112, or the movement condition or driving condition corrected in step S114. That is, the control circuit 90 inputs a drive signal to the zoom motor control unit 74, the focus motor control unit 78, the tilt motor control unit 84, and the pan motor control unit 88 based on a predetermined movement condition or drive condition. Then, the zoom motor 19, the focus motor 12, the tilt motor 83, and the pan motor 87 are driven. At this time, since the driving is performed under the movement condition corrected in step S114, the focus motor 77 is driven by the amount of focus correction corresponding to the direction change condition of the lens unit 71. At this time, it is also possible to perform focus correction before the end of tilt and pan driving in the order of signal input to the zoom motor control unit 74, the focus motor control unit 78, the tilt motor control unit 84, and the pan motor control unit 88.

  As described above, the camera according to the present embodiment performs not only the lens posture but also the driving direction and the driving speed in order to correct the focus change caused by the lens posture change caused by the tilt and pan operations. Accordingly, accurate focus correction can be performed.

  Further, it is possible to correct the attitude difference focus according to the set state by detecting the installation state of the camera.

  In the present embodiment, the ceiling-mounted installation is shown. However, in the case of stationary installation or wall-mounted installation, the posture of the lens in the gravitational direction changes even with tilt driving and pan driving. In the case of wall-mounted installation, the same effect as in the present embodiment can be obtained by performing the selection for performing the focus correction control at the time of either the tilt driving or the pan driving.

  In FIG. 6, the focus drive is shown in step S113, but the same effect as in the present embodiment can be obtained for other drive.
