Abstract
A camera is provided with a correction lens movable in two directions perpendicularly intersecting each other; a target position setter for setting a target position for the correction lens; a driver for moving the correction lens to a set target position; a detector for detecting a position at which the correction lens has been moved by a predetermined driving energy and stopped; and a posture detector for detecting a posture of the camera comparing a moved position with the target position.
Claims32
An optical apparatus comprising:
- an optical system having an optical axis;
- a correction lens movable on a plane intersecting the optical axis;
- a controller which sets a target position for the correction lens;
- a driver which drives the correction lens to a set target position;
- and
- a detector which detects a current position of the correction lens,
- wherein the controller sets a correction for the target position by comparing the current position with the target position.
