IMAGE SHAKE CORRECTING DEVICE

摘要

An image shake correcting device used for an imager comprising an imaging optical system (6) and an imaging unit (4) for converting the image of an object formed on a light-receiving surface of the imaging unit through the imaging optical system. The image shake correcting device has a variable mirror (2) disposed along the optical axis of the imaging optical system and provided with a displaceable reflective surface (2a) and an electrode (2b) for controlling the displacement of the reflective surface, a drive unit (3) for supplying a drive signal to the electrode so as to displace the reflective surface, and a correcting unit (7) for generating correction information to correct the drive signal.
