Abstract: The lens barrel is a lens barrel for forming an optical image of a subject on an imaging element, comprising a first lens unit, a second lens unit, a focus lens unit, a zoom mechanism, and a focus actuator. The focus lens unit is movably supported by the second lens unit in the optical axis direction. The operating force inputted to the zoom control is mechanically transmitted to at least one of the first lens unit and the second lens unit. The focus actuator is fixed to the second lens unit and electrically drives the focus lens unit relative to the second lens unit in the optical axis direction. The second lens unit or the focus lens unit is disposed nearest to the image plane in the optical system including the first lens element, the second lens element, and the focus lens.

Abstract: The interchangeable lens unit (2) includes the fourth lens group unit (78), the sixth lens group unit (77), the focus lens unit (75), the zoom ring unit (83), the focus motor (64) and the lens microcomputer (40). The focus motor (64) is fixed to the sixth lens group unit (77) and is configured to electrically drive the focus lens unit (75) in the optical axis direction with respect to the sixth lens group unit (77). The lens microcomputer (40) is configured to control the focus motor (64) so that the focus lens unit (75) is driven in one direction with respect to the sixth lens group unit (77) when the sixth lens group unit (77) is driven in one direction with respect to the imaging sensor (11) by the zoom ring unit (83).

Abstract: An imaging apparatus includes an imaging unit configured to capture a subject to generate an image, a detector configured to detect tilt of the imaging apparatus; a storage unit configured to store the images generated by the imaging unit with the images being related to the detection results of the detector, and a controller configured to select at least two images as images for generating a three-dimensional image from the plurality of images stored in the storage section based on the detection results related to the images.

Abstract: The blurring caused by a tiny tremor movement is eliminated, which almost perfectly without being affected by intentional camera movement by distinguishing the unintentional tremor movement from other movements (or disturbances).

Abstract: An imaging apparatus measures shake of the apparatus using a gyro sensor, performs “a center stop control” until receiving an instruction to start recording the still picture, and performs “a lens correction control” after the start of exposure in the imaging apparatus. The center stop control controls the correction lens position to stop a correction lens at an optical axis center position (position of the correction lens at which an optical axis of the imaging lenses coincides with an optical axis of a correction lens). The lens correction control controls the correction lens position to correct blurring of the image formed on an imaging element based on the measuring result. The imaging apparatus returns the correction lens to the optical axis center position before receiving a next instruction to start a next recording, and then performs the center stop control on the correction lens.

Abstract: An imaging apparatus (20) measures shake of the apparatus by a gyro sensor (9), performs “a center stop control” until receiving an instruction for start of recording the still picture, and performs “a lens correction control” after the start of exposure in the imaging apparatus. The center stop control controls the correction lens position so as to stop a correction lens at an optical axis center position which is a position of the correction lens at which an optical axis of the imaging lenses (1) coincides with an optical axis of a correction lens (2). The lens correction control controls the correction lens position so as to correct blurring of the image formed on an imaging element (3) on the basis of the measuring result. The imaging apparatus (20) returns the correction lens (2) to the optical axis center position before receiving a next instruction for start of next recording after completion of the exposure to the imaging element, and then performs the center stop control on the correction lens (2).

Abstract: A linear actuator in a simple structure with an excellent S/N characteristic has a movable coil incorporating a pair of magnetic circuits 8a and 8b. The magnetic circuit 8a comprises yokes 6a and 7a, and a magnet 5a of which polarization direction is vertical with regard to a driving direction. The magnetic circuit 8b has the same structure as 8a. As a position detector, a magnetic sensor 10 and a magnetic scale 11 are disposed opposite with each other on a stator side and on a movable element side respetively.
