Patent number: 11418711Abstract: 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.Type: GrantFiled: July 22, 2021Date of Patent: August 16, 2022Assignee: FUJIFILM CorporationInventors: Koichi Tanaka, Akihiro Uchida, Kenkichi Hayashi, Seiichi Izawa, Hideo Kobayashi
