Abstract
A processor of a lens device is configured to acquire inclination information related to at least one of an inclination of a first drive axis of a drive mechanism with respect to a first axis of an image sensor or an inclination of a second drive axis of the drive mechanism with respect to a second axis of the image sensor, and perform, with respect to the drive mechanism, control of moving a movement lens along at least one of the first axis or the second axis based on the inclination information.
Claims23
