An optical device includes a shake detection unit configured to detect shake of the optical device; a correction unit configured to correct image blur in a sensed image; a position detection unit configured to detect position of the correction unit; a correction control unit configured to control driving of a shake correction unit based on the output of the shake detection unit and on the position of the correction unit; a panning detection unit configured to detect whether the optical device is panning and detect a direction of the panning; an eccentricity direction detection unit configured to detect an eccentricity direction based on the output of the position detection unit; and a changing unit configured to change correction characteristics of the correction control unit, wherein the changing unit changes the correction characteristics of the correction control unit based on the eccentricity direction and the panning direction.
