Abstract:
A camera having an image stabilizer, comprising:a camera body;a photographic lens for forming an image of an object on an image plane of said camera body;at least one movable mirror positioned in an optical path between said photographing lens and said image plane;a vibration sensor for detecting the magnitude of a vibration and the direction thereof given to said camera body;a mirror drive mechanism for driving said movable mirror in accordance with said magnitude of said vibration and the direction thereof detected by said vibration sensor;a detector for detecting the amount of movement of said movable mirror from an initial position thereof, and the direction of the movement of said movable mirror;an AF mechanism for performing an AF operation in accordance with object distance information; anda controller for controlling said AF mechanism in accordance with said amount of movement of said movable mirror and the direction thereof, which are detected by said detector, so that said AF mechanism further performs said AF operation to compensate a variation of an optical path length that is caused by movement of said movable mirror.
