ABSTRACT:
The invention provides an image stabilizer by which, even where it is applied to an image stabilizing optical apparatus which employs an optical axis angle variation mechanism in which an optical system of the afocal type is employed, problems of interference with an imaging optical system and so forth can be solved. A plano-concave lens and a plano-convex lens form an optical system of the afocal type. A turning shaft supports the plano-concave lens for turning movement in a plane perpendicular to an optical system of the optical system while a turning shaft supports the plano-convex lens for turning movement in another plane perpendicular to the optical axis. A pair of shaking detectors, a calculation section, a pair of drive circuits, and a pair of drive motors drive the plano-concave lens and plano-convex lens to turn to compensate for or cancel hand-shaking of the optical system.
