Patent ID: 8218018

Claim:
An optical apparatus comprising: a moving frame configured to hold one of a lens and an image pickup device and to be movable in an imaging optical axis direction; a plurality of detectors arranged at one of the moving frame and a fixed portion inside an imaging apparatus and configured to detect signals in accordance with a distance to the other one, each of the plurality of detectors being configured to detect a displacement in the imaging optical axis direction; a plurality of drivers configured to drive the moving frame in the imaging optical axis direction; an elastic supporting portion configured to elastically support the moving frame to the fixed portion; a shake detector configured to detect a shake of the imaging apparatus; and a second driver configured to drive the moving frame in a direction different from the imaging optical axis direction so as to correct a shake of an image based on a signal detected by the shake detector; and a first driving target value changing portion configured to change a driving target value of the moving frame in the imaging optical axis direction in accordance with a driving amount of the moving frame in the direction different from the imaging optical axis direction, wherein the moving frame is also movable in the direction different from the imaging optical axis direction with respect to the imaging apparatus against an elastic force of the elastic supporting portion by a driving force of the second driver; and wherein when the driving amount of the moving frame in the direction different from the imaging optical axis direction increases, the first driving target value changing portion increases a driving force of the moving frame in the imaging optical axis direction.
