ABSTRACT:
A camera with a vibration correction function prevents a battery from unnecessarily exhausting due to a failure of a vibration corrective lens driving system and provides accurate vibration-resistant control. A vibration corrective lens is subjected either to a centering drive operation to drive an optical axis to a center position of the photographing system or to a resetting drive operation to drive the optical axis to the initial position. When an abnormal drive operation is detected, the centering or resetting operation ceases to supply electric power to the angular velocity detecting circuit, the motor drive circuit, and the lens displacement detecting circuit.
