摘要:
A camera includes an optical system, a housing, an image blur corrector, a displacement acquisition section, a rotary driver, a correction computer, and a drive controller. The displacement acquisition section is configured to acquire the amount of displacement of the housing. The rotary driver is configured to rotationally drive the displacement acquisition section with respect to the housing. The correction computer is configured to calculate a first correction amount at the image blur corrector from the displacement amount acquired by the displacement acquisition section. The drive controller is configured to control the operation of the rotary driver, and also controls the operation of the image blur corrector on the basis of the first correction amount.
摘要:
A camera is provided with which a small size can be achieved while ensuring good image blur correction performance. The camera (1) has an optical system (O), a housing (2), a second drive unit (12) serving as part of an image blur corrector, an imaging element (17), a first angular velocity sensor (4), an acceleration sensor (7), a sensor drive unit (240), and a drive controller (22). The first angular velocity sensor (4) is configured to acquire the rotational angle of the housing (2). The acceleration sensor (7) is configured to acquire the amount of displacement of the housing (2). A correction computer (21) calculates the amount of drive of a correcting lens (9) from the displacement amount acquired by the acceleration sensor (7), and calculates the amount of drive of the correcting lens (9) from the rotational angle acquired by the first angular velocity sensor (4) using the position of the acceleration sensor (7) as a reference. The drive controller (22) controls the operation of the second drive unit (12) on the basis of these drive amounts.

摘要:
An imaging device capable of detecting and correcting, with high accuracy, the motion (image rotation) in the rolling direction of the image caused by the camera shake during imaging without being influenced by the individual variation, temperature characteristic, and variation with time of the sensor. To correct the motion (image rotation) in the rolling direction of the image caused by the camera shake during imaging, the result of detection of the angle of inclination of the device by an angle sensor (8a) is corrected with the result of detection of the angle of inclination of the image on the basis of the feature of the captured image by an image inclination detecting section (7), and the imaging device (3) is rotated around the optical axis or an axis parallel to the optical axis according to the corrected angle of inclination of the device.

A lens barrel includes a lens frame, a guide shaft, a lead screw, a nut, and a biasing spring. The guide shaft is inserted into the lens frame. The nut is threaded onto the lead screw. The biasing member biases the lens frame toward the nut. The lens frame includes a first bearing component having a first insertion hole and a second bearing component having a second insertion hole. The guide shaft hits an inner peripheral face of the first insertion hole at a first and second contact point, and hits an inner peripheral face of the second insertion hole at a third and fourth contact point. The first and second contact points are disposed on opposing side of the third and fourth contact points using as a reference a parallel plane which extends along the direction of an optical axis and passes through a guide axis.

Lens barrel 3 includes a stationary frame 20, a drive frame 30, a rotation cam frame 70, and a first lens frame 60. The drive frame 30 is supported by the stationary frame 20 to be movable in a Y axis direction along an optical axis of an imaging optical system O and rotatable around the optical axis in response to a drive force. The rotation cam frame 70 is supported by the drive frame 30 to be movable in the Y axis direction relative to the drive frame 30 in response to the drive force. The first lens frame 60 supports a first lens group G1 included in the imaging optical system O, and is supported by the rotation cam frame 70 to be movable in the Y axis direction relative to the rotation cam frame 70 in response to the drive force.

摘要:
A digital camera includes a first lens group, a second group frame unit, a third lens group, a CCD unit, a lens barrel, and a chassis. The first lens group receives a light flux along a first optical axis. The second group frame unit receives and bends the light flux along a second optical axis after passing through the first lens group. The third lens group receives the bent light flux from the second group frame unit. The CCD unit receives the light flux passing through the third lens group. The lens barrel includes the first lens group, the second group frame unit, the third lens group, and the CCD unit. The chassis supports the lens barrel. The second optical axis is substantially parallel to the transverse direction of an object to be captured by the CCD unit when the bottom of the chassis is substantially parallel to the transverse direction of the object.
