Title: Apex angle variable prism and shake correction device using it
Inventor: SUZUKI KOJI
IPC: G03B5/00
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To realize the correction of camera shake by simple structure and to constitute a device to be an adapter type. SOLUTION: An apex angle variable prism 22Y is constituted of a piano-concave lens 36 and a convexo-plane lens 35 and an apex angle variable prism 22X is constituted of a piano-concave lens 37 and a convexo-plane lens 38. The lens 36 is turned in a vertical direction and the lens 37 is turned in a horizontal direction. When the turning angles thereof are synthesized, the movement of an optical axis becomes two-dimensional. When the lens is turned, the apex angle of the prism is changed and the transmitted optical axis thereof is varied. Since a guide means for turning the optical lenses in the direction of a curvature surface is arranged between the optical lenses by the curvature of an identical curvature center, the first and the second lenses are extremely smoothly turned with respect to the second and the fourth lenses.  When the optical axis of the specified lens is varied based on an sensor output obtained at the detecting time of the shake of a video camera, the camera shake can be corrected. Since the optical lens is cylindrical, control accuracy is high because the optical axis is not changed in the turning axis direction of the lens even when the lens is deviated in the turning axis direction thereof.
