Abstract
A lens system for compensating for shaking movement of a camera includes an objective lens system that forms the image and a compensating lens system interposed in the optical axis of the objective lens system. The compensating lens elements are driven by electro-mechanical transducers, which provides a compact system permitting a relatively small lens construction. A driving shaft is frictionally coupled to a support for the compensating lens elements and is attached to an electro-mechanical transducer, for example, a piezoelectric element that expands and contracts responsive to a pulse wave. A movement detector monitors the objective lens system and calculates an amount of shaking compensation needed, which is provided to a pulse generator.
