Abstract
An optical device has an image blurring motion compensation mechanism with a locking device. When centering of a blurring motion compensation optical system is not performed, it is possible to lock the optical system but, at the same time, worsen the blurring motion compensation effect. The optical device with a blurring motion compensation mechanism is able to prevent such image blur worsening by constructing the blurring motion compensation mechanism from a blurring motion detector to detect blurring motion, a blurring motion compensation optical system to compensate for blurring motion detected by the detector by moving the optical axis of the optical system, a blurring motion compensation system drive device to drive the blurring motion compensation optical system, and a blurring motion control device to control the blurring motion compensation optical system drive device, based on the output of the blurring motion detector. The blurring motion control device includes a locking mechanism and a centering detection device to decide whether to perform a centering operation to move the blurring motion compensation optical system to a predetermined initial position. A locking control device causes operation of the locking mechanism based on the decision result of the centering detection device.
