As shown in the figure, on the inner side of the lens barrel 52, a P guide shaft 54P is disposed along the pitch direction (P direction in the figure), and Y along the yaw direction (Y direction in the figure). A guide shaft 54Y is provided.

  A P slider 56P is slidably supported on the P guide shaft 54P, and a Y slider 56Y is slidably supported on the Y guide shaft 54Y. The P slider 56P is provided with a y guide shaft 58Y along the Y direction, and a lens holding frame 60 holding the correction lens 3A is slidably supported on the y guide shaft 58Y. The Y slider 56Y is provided with a p guide shaft 58P along the P direction, and the lens holding frame 60 is slidably supported by the p guide shaft 58P.

  The P slider 56P is driven by a P coil motor 66P composed of a coil 62P and a magnet 64P and slides in the P direction. The coil 64P constituting the P coil motor 66P is attached to the P slider 56P, and the magnet 64P is attached to the lens barrel 52.

  In the camera shake correction apparatus 50 configured as described above, when the P coil motor 66P is driven, the P slider 56P moves in the P direction, whereby the lens holding frame 60 moves in the P direction, and the correction lens 3A. Moves in the P direction. When the Y coil motor 66Y is driven, the Y slider 56Y moves in the Y direction, whereby the lens holding frame 60 moves in the Y direction, and the correction lens 3A moves in the Y direction.

  When the movement of the P slider 56P is detected by the P position sensor 70P, the CPU 134 drives the P coil motor 66P via the P coil motor driver 72P, and moves the correction lens 3A so as to cancel the movement. When the movement of the Y slider 56Y is detected by the Y position sensor 70Y, the Y coil motor 66Y is driven via the Y coil motor driver 72Y, and the correction lens 3A is moved so as to cancel the movement. As a result, image blur based on camera shake is corrected.

  As described above, in the digital camera 10 of the present embodiment, the camera shake correction device 50 can be used to perform fine framing adjustment. Hereinafter, the function of fine adjustment of framing using the camera shake correction apparatus 50 will be described.

  As described above, the camera shake correction device 50 drives the P coil motor 66P to move the correction lens 3A in the P (pitch: vertical) direction, and drives the Y coil motor 66Y, thereby correcting the lens 3A. Moves in the Y (yaw: left and right) direction. When the correction lens 3A is moved in the P direction, the area photographed by the CCD 114 moves in the vertical direction. When the correction lens 3A is moved in the Y direction, the area photographed by the CCD 114 moves in the left-right direction. Therefore, by driving the Y coil motor 66Y and the P coil motor 66P and moving the correction lens 3A in the P direction and the Y direction, the photographing area can be moved up and down, left and right, and fine adjustment of framing can be performed. .

  The direction of movement of the correction lens 3A (= instruction of the direction of movement of the photographing area) is performed by the cross key 34. When the upper key of the cross key 34 is pressed, the correction lens 3A moves upward and moves downward. When the key is pressed, the correction lens 3A moves downward. When the right key of the cross key 34 is pressed, the correction lens 3A moves to the right, and when the left key is pressed, the correction lens 3A moves to the left.

  The correction lens 3A moves by a predetermined amount in the direction of the pressed key when the cross key 34 is pressed once. Therefore, the amount of movement of the correction lens 3A can be adjusted by adjusting the number of times of pressing.

  As described above, the fine adjustment function of the framing using the camera shake correction device 50 is operated by setting the camera shake correction function changeover switch 26 to “framing adjustment position” or “camera shake correction + framing adjustment position”. To do.

  First, the processing operation of the digital camera 10 when the camera shake correction function selector switch 26 is set to the “framing adjustment position” will be described. As described above, when the camera shake correction function changeover switch 26 is set to the “framing adjustment position”, the camera shake correction function is turned off, and only the framing adjustment function is effectively operated.

  FIG. 6 is a flowchart showing the procedure of the processing operation of the digital camera 10 when the camera shake correction function selector switch 26 is set to the “framing adjustment position”.

  First, the CPU 134 determines whether or not the camera shake correction function selector switch 26 is set to the “framing adjustment position” based on the input from the operation unit 132 (step S10).

  If it is determined that the camera shake correction function changeover switch 26 is set to the framing adjustment position, the camera shake correction function is turned off, while the framing adjustment function is turned on (step S11), and the center of the correction lens 3A (optical axis O ′ ) Is moved to the center of the movable range (imaging optical axis O) (step S12).

  Thereafter, the CPU 134 determines whether or not the cross key 34 has been pressed based on the input from the operation unit 132 (step S13). If it is determined that the cross key 34 has been pressed, the correction lens 3A is moved by driving the P coil motor 66P or the Y coil motor 66Y so that the correction lens 3A moves in the direction of the pressed key. (Step S14). As a result, the imaging region slightly moves in the direction in which the cross key 34 is pressed.

  After moving the correction lens 3A, the CPU 134 determines whether or not the shutter button 20 has been fully pressed based on an input from the operation unit 132 (step S13), and performs shooting when it is determined that the shutter button 20 has been fully pressed. (Step S16).

  On the other hand, if it is determined that the shutter button 20 is not fully pressed, the process returns to step S13, and it is determined again whether or not the cross key 34 is pressed based on the input from the operation unit 132 (step S13). If it is determined that the cross key 34 has been pressed, the correction lens 3A is moved by driving the P coil motor 66P or the Y coil motor 66Y so that the correction lens 3A moves in the direction of the pressed key. (Step S14).

  At this time, the user operates the cross key 34 while viewing the through image displayed on the liquid crystal monitor 30 to finely adjust the shooting region, that is, the framing. Then, when an image of a desired shooting area is displayed on the liquid crystal monitor 30, the shutter button 20 is fully pressed to perform shooting.

  As described above, when the camera shake correction function selector switch 26 is set to the “framing adjustment position”, the camera shake correction device 50 can be used to perform fine framing adjustment, and the cross key 34 is pressed. The imaging area moves slightly in the direction that is set.

  Next, the processing operation of the digital camera 10 when the camera shake correction function changeover switch 26 is set to “camera shake correction + framing adjustment position” will be described.

  As described above, when the camera shake correction function changeover switch 26 is set to “camera shake correction + framing adjustment position”, both the function of camera shake correction and the function of framing adjustment operate effectively.

  FIG. 7 is a flowchart showing a procedure of processing operations of the digital camera 10 when the camera shake correction function changeover switch 26 is set to “camera shake correction + framing adjustment position”.

  First, the CPU 134 determines whether or not the camera shake correction function changeover switch 26 is set to “camera shake correction + framing adjustment position” based on an input from the operation unit 132 (step S20).

  When it is determined that the camera shake correction function changeover switch 26 is set to the framing adjustment position, both the camera shake correction function and the framing adjustment function are turned on (step S21), and sensor outputs from the P position sensor 70P and the Y position sensor 70Y. Based on this, the P coil motor 66P and the Y coil motor 66Y are driven to correct image blur based on camera shake.

  Thereafter, the CPU 134 determines whether or not the cross key 34 has been pressed based on the input from the operation unit 132 (step S22). If it is determined that the cross key 34 has been pressed, the P-coil motor 66P or the Y-coil motor 66Y is driven to move the correction lens 3A so that the correction lens 3A moves in the direction of the pressed key ( Step S23). During this time, the CPU 134 continuously performs camera shake correction processing. If camera shake has occurred, the correction lens 3A is moved with the correction amount added. As a result, it is possible to finely adjust the framing by moving the shooting region slightly in the direction in which the cross key 34 is pressed while correcting the camera shake.

  After moving the correction lens 3A, the CPU 134 determines whether or not the shutter button 20 has been fully pressed based on an input from the operation unit 132 (step S24), and executes shooting when it is determined that the shutter button 20 has been fully pressed. (Step S25).

  On the other hand, if it is determined that the shutter button 20 has not been pressed, the process returns to step S22, and it is determined again whether or not the cross key 34 has been pressed based on the input from the operation unit 132 (step S22). If it is determined that the cross key 34 has been pressed, the correction lens 3A is moved by driving the P coil motor 66P or the Y coil motor 66Y so that the correction lens 3A moves in the direction of the pressed key. (Step S23).

  At this time, the user operates the cross key 34 while viewing the through image displayed on the liquid crystal monitor 30 to finely adjust the shooting region, that is, the framing. Then, when an image of a desired shooting area is displayed on the liquid crystal monitor 30, the shutter button 20 is fully pressed to perform shooting.

  As described above, when the camera shake correction function changeover switch 26 is set to “camera shake correction + framing adjustment position”, the framing can be finely adjusted while the camera shake correction function is enabled. The photographing area can be moved minutely in the pushing direction.

  As described above, according to the digital camera 10 of the present embodiment, fine adjustment of framing can be easily performed using the camera shake correction function provided in the camera.

  In addition, the fine framing adjustment function uses the existing camera shake correction device 50, and thus can be configured without any additional components.

  Furthermore, since the camera shake correction device 50 employs an optical camera shake correction method, image quality does not deteriorate.

  In the above embodiment, the user manually switches the function of the camera shake correction device 50 by operating the camera shake correction function changeover switch 26. However, the function is automatically switched according to the shooting conditions. May be.

  For example, when shooting with a camera mounted on a tripod, such as self-timer shooting, bulb shooting, or shooting at a speed slower than a predetermined shutter speed (long exposure shooting), the camera shake correction function may be turned off. Since it is preferable, when such shooting conditions are set, the camera shake correction function is automatically turned off and only the framing adjustment function is turned on.

  In this case, for example, the settings for self-timer shooting and bulb shooting are set on the menu screen. When it is detected that self-timer shooting or bulb shooting is selected on this menu screen, the camera shake correction function is turned off. Turn on the framing adjustment function. In addition, a dedicated button for performing self-timer shooting or bulb shooting may be provided, and pressing of this button may be detected to switch the function of the camera shake correction device.

  For long exposure photography, for example, a manually set shutter speed is detected, and when it is detected that the shutter speed is set to a prescribed shutter speed (for example, 1/2 second) or less, a function for correcting camera shake is performed. And turn on the framing adjustment function.

  In this way, it is possible to automatically detect a situation where a camera is mounted on a tripod, automatically turn off the camera shake correction function, and turn on only the framing adjustment function. Degradation of image quality based on detection and unnecessary power consumption can also be suppressed.

  In this embodiment, a device that corrects image blur by moving a part of the photographic lens is used as the camera shake correction device. However, the camera shake correction method of the camera shake correction device is not limited to this. It is not limited to. For example, a camera shake correction apparatus that corrects image blur by moving the image sensor in a direction that cancels blur may be used.

  In the above embodiment, the case where the present invention is applied to a digital camera has been described as an example. However, the application of the present invention is not limited to this, and an optical camera shake correction device is provided. The present invention can be applied to all photographing devices (for example, a silver salt camera, a video camera, a mobile phone with a camera, etc.)
