Abstract

Abstract An image shake compensating device includes a compensating member for compensating for an image shake taking place on an image forming plane of an optical instrument; a detecting circuit for detecting, through the displacement state of the compensating member, the shaking state of the optical instrument causing the image shake; and a driving circuit for driving the compensating member in response to an output of the detecting circuit.
