Abstract
An optical unit with shake correcting function may include a movable module on which at least an optical element is mounted, a fixed body which supports the movable module, a shake detection sensor which detects a shake of the movable module, a drive mechanism for shake correction for swinging the movable module on the fixed body on the basis of a detection result of the shake detection sensor to correct the shake of the movable module, and a control section which controls the drive mechanism for shake correction on the basis of the detection result of the shake detection sensor. The shake detection sensor is a gyroscope mounted on the movable module and the control section controls the drive mechanism for shake correction so as to cancel the shake detected by the gyroscope.
