摘要： A lens interchangeable digital camera includes an image sensor in which a subject image is formed on an imaging surface through an imaging optical system including a zoom lens and a sensor movement type shake correction mechanism that performs a sensor movement operation of moving the image sensor in a direction to cancel a shake. A zoom operation determination unit determines whether or not a zoom operation in which the zoom lens moves is being performed. In a case where the zoom operation determination unit determines that the zoom operation is being performed, an operation deciding unit prohibits a shift operation which is at least a part of a sensor movement operation which is allowed while the zoom operation is stopped.

摘要： Provided are a lens barrel and an imaging device, with which it is possible to lock an optical member of which the movement in an optical axis direction is made free in a case where there is no electrification, particularly to hold the optical member in a locked state without use of electric power. A movable frame that holds a focus lens is driven in the optical axis direction by a linear motor. In a case where the movable frame is to be locked with the linear motor being not electrified, the movable frame (engagement portion) is caused to abut onto a restriction portion at an end portion of the movable range of the movable frame and a locking ring is caused to rotationally move to a locking position by an electric actuator. Accordingly, the movable frame is fixed by the restriction portion and a locking portion of the locking ring to become unable to move. The electric actuator includes a worm gear as a power transmission mechanism and it is possible to hold the locking ring at the locking position by means of an irreversible rotation function of the worm gear.

摘要： The lens interchangeable digital camera includes a sensor movement type shake correction mechanism that performs a sensor movement operation of moving an image sensor in a direction to cancel a shake. A characteristic data acquisition unit acquires optical characteristic data corresponding to optical characteristics of an imaging optical system of a lens unit mounted on a body mount. A determination unit determines whether or not adaptive optical characteristic data that can be handled by an image correction unit that performs image correction based on the optical characteristic data can be acquired. An operation deciding unit prohibits a shift operation which is at least a part of a sensor movement operation in an uncorrectable state where the image correction based on the adaptive optical characteristic data is not possible since the adaptive optical characteristic data cannot be acquired.

摘要： In a state in which a position sensor for focusing is viewed in the direction of an optical axis, a line connecting the position sensor for focusing to the optical axis is set as a first reference line and a line orthogonal to the first reference line and passing through the optical axis is set as a second reference line. The position sensor for focusing is disposed in a first region of the first region and a second region partitioned by the second reference line. An X-direction VCM and a Y-direction VCM are arranged in the second region. The influence of magnetism from the X-direction VCM and the Y-direction VCM on the position sensor for focusing is suppressed.

摘要： A zoom lens barrel houses plural lens frames holding plural movable lens units and supporting the plural movable lens units so that the movable lens units are movable forward and rearward along an optical axis. The zoom lens barrel includes a first lens frame and a second lens frame of the plural lens frames adjacent to each other, and plural first linear motors and plural second linear motors that move the first lens frame and the second lens frame forward and rearward independently for focusing associated with zooming. The plural first linear motors and the plural second linear motors are arranged in a plane that is perpendicular to the optical axis and also alternately on the same circumference that has a center on the optical axis.
