Example 1
Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a schematic configuration of a digital camera 1 as an optical apparatus according to an embodiment of the present invention. In this embodiment, description will be made using a so-called compact digital camera in which a lens barrel and a camera body are integrated.

  The digital camera 1 according to the present embodiment includes a zoom lens unit 101 including a zoom lens that performs zooming by changing a zoom position, and a zoom drive control unit 102 that drives and controls the zoom lens unit 101. The digital camera 1 also includes a shift lens unit 103 that holds a shift lens as a shake correction optical system that can move in a direction substantially perpendicular to the photographing optical axis, and a shift lens drive that drives and controls the shift lens unit 103. A control unit 104 is provided. Note that the shift lens unit 103 is an electronic image blur correction method that changes the cutout range of an image even when the image pickup unit 109 including the image pickup device is driven in a direction substantially perpendicular to the photographing optical axis. It may be.

  The digital camera 1 further includes an aperture / shutter unit 105 that performs the aperture operation and shutter operation of the optical system, and an aperture / shutter drive control unit 106 that drives and controls the aperture / shutter unit 105. In addition, a focus lens unit 107 that performs focus adjustment and a focus drive control unit 108 that drives and controls the focus lens unit 107 are provided. In addition, an imaging unit 109 including an imaging device that converts an optical image that has passed through each lens group into an electrical signal is provided.

  In the digital camera 1, conversion processing of the electrical signal output from the imaging unit 109 into a video signal is performed by the imaging signal processing unit 110, and processing according to the use of the video signal output from the imaging signal processing unit 110 is performed. This is performed by the video signal processing unit 111.

  In the digital camera 1, a display unit 112 including a display performs image display as necessary based on a signal output from the video signal processing unit 111.

  The digital camera 1 includes a power supply unit 113 that supplies power to the entire digital camera according to applications, an external input / output terminal unit 114 for inputting / outputting communication signals and video signals to / from the outside, and the digital camera 1. An operation unit 115 for operation is provided. Various data such as video information obtained by photographing is stored in the storage unit 116. The control unit 117 performs overall control of the digital camera 1.

  Next, the operation of the digital camera 1 configured as described above will be described. The operation unit 115 is a shutter release button as an instruction member configured such that a first switch (SW1) for instructing an imaging preparation operation and a second switch (SW2) for instructing an imaging operation are sequentially turned on in accordance with the push amount. (Not shown). The first switch (SW1) is turned on when the shutter release button is depressed approximately halfway, and the second switch (SW2) is turned on when the shutter release button is depressed to the end.

  When the first switch (SW1, shooting preparation instruction) is turned on, the focus drive control unit 108 drives the focus lens unit 107 to perform focus adjustment, and the aperture / shutter drive control unit 106 controls the aperture / shutter unit 105. Drive to set the exposure amount appropriately. When the second switch (SW2, shooting instruction) is turned on, an optical image is exposed to the imaging unit 109, and image data obtained based on the electrical signal converted by the imaging element is captured by the imaging signal processing unit 110, It is stored in the storage unit 116 via 111.

  At this time, if there is an instruction to turn on the image stabilization from the operation unit 115, the control unit 117 instructs the shift lens drive control unit 104 to perform the image stabilization operation, and the shift lens drive control unit 104 that has received this instruction Anti-vibration operation is performed until the instruction is given.

  In addition, when the operation unit 115 has not been operated for a certain period of time, the control unit 117 issues an instruction to shut off the power source of the display included in the display unit 112 for power saving.

  Further, the digital camera 1 can select a still image shooting mode for performing still image shooting or a moving image shooting mode for mainly performing operation shooting by operating the operation unit 115. For this reason, in each photographing mode, the operating condition of each actuator (movable element) constituting the digital camera 1 can be changed.

  When an instruction for zooming by the zoom lens is input via the operation unit 115, the zoom drive control unit 102 that has received the instruction via the control unit 117 drives the zoom lens unit 101 to indicate the designated zoom. Move the zoom lens to the position. Further, based on the image information processed by the imaging signal processing unit 110 and the video signal processing unit 111, the focus drive control unit 108 drives the focus lens unit 107 to perform focus adjustment.

  FIG. 2 is a block diagram showing an internal configuration of the shift lens drive control unit 104.

  The shake detection unit 201 detects the angular velocity component of shake in the vertical and horizontal directions (pitch and yaw directions) of the digital camera 1 in the normal posture (the posture in which the length direction of the image frame substantially coincides with the horizontal direction). A signal (angular velocity signal) is output. The shake detection sensor includes, for example, a vibration gyro, and includes a pitch direction shake detection unit 201a and a yaw direction shake detection unit 201b as vibration detection means for detecting vibration applied to the digital camera 1.

  In addition to the vibration gyro, the shake detection unit 201 may be a sensor such as an acceleration sensor, may detect a motion vector between images, or may detect a shake by an external force applied to the shift lens unit 103. You may do it. Also, a plurality of different types of sensors may be used. For example, when the shake detection unit 201 is a gyro sensor, it detects angular velocity components of vertical and horizontal shakes of the digital camera 1 and outputs an angular velocity signal.

  In the present embodiment, in the normal posture (the posture in which the length direction of the image frame substantially coincides with the horizontal direction), the optical axis toward the shooting subject is the Z axis, the horizontal direction of the digital camera 1 is the X axis, and the vertical direction is the vertical direction. The Y axis is assumed. Therefore, the shake of the digital camera 1 in the vertical direction (around the X axis) is the pitch direction, and the shake in the horizontal direction (around the Y axis) is the yaw direction. The pitch direction shake detection unit 201a detects an angular velocity component of the shake in the pitch direction of the digital camera 1 in the normal posture, and outputs a shake signal (angular speed signal). The yaw direction shake detection unit 201b detects an angular velocity component in the yaw direction among shakes in the yaw direction (around the Y axis) of the digital camera 1 in a normal posture, and outputs a shake signal (angular speed signal).

  The image shake correction control unit 202a calculates a shift lens correction position control signal in the pitch direction based on the shake signal from the pitch direction shake detection unit 201a. Similarly, based on the shake signal of the yaw direction shake detection unit 201b, the image shake correction control unit 202b calculates a shift lens correction position control signal in the yaw direction. The shift lens correction position control signal in each of the pitch and yaw directions is a signal representing the drive target position of the shift lens unit 103.

  Further, the Hall elements (position detection means) of the position detection units 205a and 205b detect the positions of the shift lens unit 103 in the pitch direction and the yaw direction by detecting the magnetic field of the magnet attached to the shift lens unit 103. Output a position signal. In the present embodiment, the Hall element is used as the position detecting means, but a position detecting method such as PSD (Position Sensitive Detector) may be used.

  The PID unit 203a and the PID unit 203b obtain control amounts from deviations between the shift lens correction position control signals output from the image blur correction control units 202a and 205b and the position signals output from the position detection units 205a and 205b, respectively. The drive command signal is output. Here, the PID control is a kind of feedback control, and is a control in which an input value is controlled by three elements: a deviation between an output value and a target value, an integral value thereof, and a differential value. In PID control, an operation that changes an input value in proportion to a deviation is called a proportional operation or a P operation. Further, the operation for changing the input value in proportion to the integral value of the deviation is referred to as integration operation or I operation, and the operation for changing the input value in proportion to the differential value of deviation is referred to as differentiation operation or D operation.

  The drive unit 204a and the drive unit 204b as drive means drive the shift lens unit 103 in the X-axis and / or Y-axis directions based on drive command signals sent from the PID units 203a and 203b, respectively. In this way, the PID units 203a and 203b perform feedback control so that the position signal converges on the corrected position control signals sent from the image blur correction control units 202a and 202b, respectively.

  Further, the shift lens correction position control signal in the pitch direction of the image shake correction control unit 202a calculated based on the shake signal from the pitch direction shake detection unit 201a is a signal representing the movement target position (shake correction position) in the pitch direction. is there. Similarly, the shift lens correction position control signal in the yaw direction of the image shake correction control unit 202b calculated based on the shake signal from the yaw direction shake detection unit 201b is a signal representing the movement target position (shake correction position) in the yaw direction. It is.

  Therefore, the position of the shift lens unit 103 is moved in the direction in which the image blur due to the shake of the digital camera 1 is corrected by the shift lens correction position control signals output from the image shake correction control units 202a and 202b. In this way, even if the shift lens unit 103 that performs shake correction moves in the vertical and horizontal directions orthogonal to the optical axis, and the camera shake or the like occurs in the digital camera 1, image blur can be reduced.

  FIG. 3 is a block diagram of the image blur correction control unit 202. After shake detection by the shake detection unit 201, the shake signal as the shake detection result is amplified to a specific magnification by the amplifier 301 which is signal amplification means. The amplified shake signal is digitized by A / D conversion means 302 that converts an analog signal into a digital signal.

  Next, the filter processing is performed by a digital high-pass filter (hereinafter HPF) 303 and a digital low-pass filter (hereinafter LPF) 304 which are filter units having a variable cutoff frequency that allows a predetermined frequency to pass. The filtered shake signal is converted into an actual shift lens drive amount target position by the image shake correction amount calculation unit 305, and then a control amount is calculated by the PID unit 203 from the current position and the target position of the shift lens. . Then, an image blur correction member (shift lens unit 103) for correcting image blur is driven.

  Further, the cut-off changing unit 306 changes the cut-off frequencies of the HPF 303 and the LPF 304 according to an instruction from the panning operation determination unit 307. When it is determined that panning or tilting, the cutoff frequency of the HPF 303 is increased (narrowing the pass band of the low frequency band component) to make it difficult to follow the low frequency band component of the shake and / or the cutoff frequency of the LPF 304 is integrated. Change so that the time constant becomes longer. In this embodiment, the cutoff frequencies of both the HPF 303 and the LPF 304 are changed, but either one may be used. Further, a method of gradually subtracting the offset amount from the shake correction amount may be used.

  The panning operation determination unit 307 determines whether or not there is a panning operation or a tilting operation using the shake signal digitized by the A / D conversion unit 302. The information of the shake signal digitalized by the A / D conversion unit 302, the subject information detection unit 308 that detects subject information, and the zoom magnification scaling unit 309 that stores the current zoom magnification information are included. Based on this, the cutoff change unit 306 issues a change instruction. Note that panning or tilting determination may be performed using a signal that has been filtered by the LPF 304 instead of the shake signal digitalized by the A / D conversion unit 302.

  The main subject setting unit 310 serving as the first setting means sets the main subject on the image sensor by the user or by a camera function (for example, a face detection function), and sets the position coordinates of the main subject on the imaging surface as the subject. The information is sent to the information detection unit 308. In setting the main subject at this time, the photographer can set an arbitrary subject by automatically setting the main subject recognition function of the digital camera 1 such as face recognition, or by operating an operation member of an image sensor such as a touch panel or an operation button. Can be set. Although the position of the main subject is used here, the main subject may be detected not by a point but by an area. In that case, the position of the subject may be determined by using the center coordinates and the barycentric coordinates of the area to be the main subject.

  A framing target position setting unit 311 serving as a second setting unit sets the framing target position of the main subject. The framing target position is a position on the screen where the photographer wants to place the main subject. For example, by operating an operation member such as a touch panel or operation buttons, the photographer can set an arbitrary framing target position. Further, the framing target position may be a point or a region. In the case of an area, the position of the framing target may be set using the center coordinates and the barycentric coordinates of the area set as the main subject, or the entire area may be set as the position of the framing target.

  The subject information detection unit 308 calculates how far the main subject set by the main subject setting unit 310 is away from the framing target position set by the user using the framing target position setting unit 311. (Distance S in FIG. 5A) The distance S between the main subject position and the framing target position is input to the panning operation determination unit 307.

  Next, an operation when performing shooting will be described with reference to the flowchart of FIG. FIG. 5 is a diagram for explaining the distance S between the main subject position and the framing target position. 6A is a diagram for explaining the relationship between the magnitude of the shake signal and the cutoff frequency of the HPF 303, and FIG. 6C is a diagram for explaining the relationship between the magnitude of the shake signal and the cutoff frequency of the LPF 304. . However, the shake signal here exemplifies one of the pitch direction and the yaw direction, but the other control is also the same. 6B is a diagram for explaining the relationship between the distance S between the main subject position and the framing target position and the cutoff frequency of the HPF 303. FIG. 6D shows the distance S between the main subject position and the framing target position. It is a figure explaining the relationship of the cut-off frequency of LPF304.

  First, main subject setting is performed by setting by a photographer or automatic determination of the digital camera 1, and position coordinates on the imaging surface of the main subject are obtained (S401). The framing target position on the shooting angle of view is set by the photographer, and the framing target position setting unit 311 converts and sets the framing target position information on the imaging surface (S402). The shake detection unit 201 acquires an angular velocity component of the shake and outputs a shake signal (angular velocity signal) (S403). The subject information detection unit 308 determines how far the main subject set by the main subject setting unit 310 is away from the framing target position set by the user using the framing target position setting unit 311 (distance S in FIG. 5A). Is obtained as subject information (S404). Also, the current zoom magnification information stored in the zoom magnification changing unit 309 is acquired (S405).

  Based on the acquired shake signal (angular velocity signal), subject information, and zoom magnification information, the panning operation determination unit 307 performs pan operation determination. First, in S406, if the magnitude of the shake signal is equal to or greater than a predetermined value (threshold value b in FIG. 6A), it is determined that the digital camera 1 is in the panning or tilting state, and the process proceeds to S407. In S407, the cutoff changing unit 306 sets the cutoff frequency of the HPF 303 to be high (p1 or more, solid line 61) as shown in FIG. 6A regardless of the distance S between the main subject position and the framing target position. Further, the cut-off changing unit 306 lowers the cut-off frequency of the LPF 304 (below q1 and a solid line 63) as shown in FIG. 6C regardless of the distance S between the main subject position and the framing target position. Here, by lowering the cutoff frequency of the LPF 304, the integration time constant in the LPF 304 is shortened. If the magnitude of the shake signal is less than the predetermined value (threshold value b), it is determined that the digital camera 1 is not in the panning or tilting state, and the process proceeds to S408.

  In S408, the cut-off changing unit 306 lowers the cut-off frequency of the HPF 303 (p1 to p2 in FIG. 6A) and raises the cut-off frequency of the LPF 304 than in panning or tilting (FIG. 6 ( c) q1 to q2). In this embodiment, as shown in the broken line 62 in FIG. 6A and the broken line 64 in FIG. 6C, when the magnitude of the shake signal exceeds the threshold value a (smaller than the threshold value b), panning or You may determine with tilting. Further, as shown in FIGS. 6B and 6D, the cutoff frequencies of the HPF 303 and the LPF 304 are set between p1 and p2 and between q1 and q2 based on the distance S between the main subject position and the framing target position.

  At this time, as the distance S between the main subject position and the framing target position is larger, the photographer needs to perform a framing operation for adjusting the main subject position to the target position. Therefore, when the distance S is large as shown in FIG. 6B, the cutoff frequency of the HPF 303 is increased (set to p1, solid line 61), and the cutoff frequency of the LPF 304 is decreased as shown in FIG. 6D. (Set to q1, solid line 63). That is, since the cutoff frequency of the HPF 303 is increased as the distance S increases, the low frequency band component of the shake signal is not fed back to the image shake correction. For this reason, image blur correction is performed centering on fine shake such as camera shake, and the follow-up capability of image shake correction for a motion in which a low frequency band component becomes large as in framing adjustment is reduced. Therefore, it is possible to provide smooth framing without erroneously determining framing as camera shake and without disturbing the photographer's framing operation.

  When the distance between the main subject position and the framing target position is small as shown in FIG. 5B, the framing operation ends because the framing target position and the main subject position are close or coincident with each other. It is highly probable that it has been or is being terminated. Therefore, when the distance S is small as shown in FIG. 6B, the cutoff frequency of the HPF 303 is lowered (set to p2, broken line 62), and the cutoff frequency of the LPF 304 is raised as shown in FIG. 6D. (Set to q2, broken line 64). By doing so, it is possible to improve the follow-up performance against the shake, and it is possible to sufficiently obtain the shake correction effect by performing the image shake correction up to the low frequency band component of the shake.

  Further, as shown in FIGS. 6A and 6C, when the magnitude of the shake signal exceeds, for example, the threshold value b, it is determined that panning or tilting is performed, so that the cutoff frequency of the HPF 303 is increased and the cutoff frequency of the LPF 304 is increased. The frequency is set to be low.

  As shown in FIGS. 6B and 6D, as the distance between the main subject position and the framing target position in the subject information gradually approaches, the cutoff frequency of the HPF 303 is gradually lowered and the cutoff frequency of the LPF 304 is increased. To do. In this way, image blur correction is performed up to the low frequency band component of shake. As a result, when the distance between the main subject position and the framing target position is far, the movement of the framing adjustment is relatively difficult to be corrected by image blur correction, and when it is close, the image blur due to the shake is relatively corrected. Correction can be performed.

  Furthermore, when changing the cutoff frequency, the cutoff frequency may be changed according to the zoom position in consideration of the fact that the image shake due to camera shake becomes smaller as the zoom magnification is closer to the wide side. Specifically, when the main subject position and the framing target position are close to or the same as in the panning or tilting state, the cutoff frequency of the HPF 303 is decreased and the cutoff frequency of the LPF 304 is increased as the zoom magnification is closer to the tele side. . Then, the above-described flow is repeated while the camera shake correction function is operating.

  In the above-described embodiments, the longer the distance S between the main subject position and the framing target position, that is, the farther the main subject position and the framing target position are, the more difficult the camera shake correction becomes effective by increasing the cutoff frequency of the HPF 303 (the follow-up performance is low). ) And make framing easier. In addition, the shorter the distance S between the main subject position and the framing target position, that is, the closer the main subject position and the framing target position are, the lower the cutoff frequency of the HPF 303 is corrected to the low frequency component (increase the followability). The effect of image blur correction is obtained.

  As a modification, the cutoff frequency of the HPF 303 and the LPF 304 may be changed by a shooting preparation operation. That is, when SW1 is pressed, a shooting preparation operation is started, so that there is a high possibility that framing adjustment has been completed. Therefore, regardless of the distance S between the main subject position and the framing target position, the cut-off frequency of the HPF 303 may be lowered and the cut-off frequency of the LPF 304 may be raised to obtain an image blur correction effect when SW1 is pressed.

(Example 2)
The second embodiment of the present invention will be described below with reference to the block diagram of FIG. 7 and the flowchart of FIG. The same reference numerals as those in FIG. 3 are the same elements.

  Compared with the first embodiment, the second embodiment does not have the main subject setting unit 310 and the framing target position setting unit 311, and has a framing operation detection unit 708 instead of the subject information detection unit 308. The framing operation detection unit 708 detects that the framing operation member (not shown) attached to the digital camera 1 has been operated, and the photographer is in the framing state.

  First, the shake detection unit 201 acquires an angular velocity component of shake and outputs a shake signal (angular velocity signal) (S801). Next, the framing operation detection unit 708 detects that a framing operation member (not shown) attached to the digital camera 1 has been operated, and detects whether or not it is in a framing state (S802). Also, the current zoom magnification information stored in the zoom magnification changing unit 309 is acquired (S803). In S804, panning and tilting operation determination is performed based on the acquired shake signal (angular velocity signal), the detection information of the framing operation acquired in S802, and the zoom magnification information acquired in S803.

  In this way, during framing, the cutoff changing unit 306 increases the cutoff frequency of the HPF 303 and decreases the cutoff frequency of the LPF 304 compared to when not in the framing state (when the framing operation member is not operated). As a result, it is less likely that a shooting angle of view change due to framing is erroneously determined as camera shake. When not in the framing state (when the framing operation member is not operated), the cutoff changing unit 306 lowers the HPF 303 cutoff frequency and raises the cutoff frequency of the LPF 304 compared to when in the framing state. By doing so, it is possible to obtain a sufficient camera shake correction effect. In this way, by changing the cutoff frequency according to the distance between the main subject position and the framing target position in the subject information, it is possible to perform image blur correction so that the photographer does not feel uncomfortable.

  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.

  In this embodiment, a digital compact camera is taken as an example of an optical device, but an imaging device or an optical device such as a digital video camera, a digital single-lens camera, a surveillance camera, or a mobile device with a camera may be used.
