Abstract
A device used in an optical system such as a camera that makes it possible to perform suitable motion compensation, even during panning. The device includes a motion detection unit which detects motion, a motion compensation optical system which compensates for image motion, a motion compensation drive unit which drives the motion compensation optical system, a motion compensation control unit which calculates, from the output of the motion detection unit, a target position signal of the motion compensation optical system, and based on this target position signal, controls the motion compensation drive unit, a position detection unit which detects the position of the motion compensation optical system, and a center bias calculating unit which, based on the position data obtained from the position detection unit, corrects the target position signal towards the center of possible movement of the motion compensation optical system.
