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.

Imaging device including shake correction mechanism, and operation method and operation program thereof

An imaging device stores a focal length and a position of a focus lens in a storage unit in a case in which a focal state is determined to be a focus state in which a subject is in focus and at least one of the imaging device or the subject is determined to be stationary; generates tracking data for changing the position of the focus lens according to a change in focal length, using a plurality of stored focal lengths and a plurality of stored positions of the focus lens; and performs a zoom tracking control using the generated tracking data.

Imaging device, imaging method, and program

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.
