Abstract:
A motion compensation device, comprising:a motion detection unit to detect motion and to output a motion detection signal representing the detected motion;a motion compensation optical system to correct motion;a drive unit to drive the motion compensation optical system;a position detection unit to detect a position of the motion compensation optical system and to output a position detection signal representing the detected position;a target drive position calculating unit to calculate a target drive position of the motion compensation optical system based on the motion detection signal, and to output a target drive position signal; anda target drive position signal correction unit to correct the target drive position signal based on the position detection signal, to bias drive the motion compensation optical system toward a center of a drive range of the motion compensation optical system,wherein the target drive position signal correction unit reduces a correction value for the target drive position signal when the position detection signal exceeds a predetermined value.
