Blur correcting apparatus and method for camera

摘要

A blur correcting apparatus for a camera which includes a shake detecting mechanism and a blur correcting optical element which is movable in a plane normal to the optical axis of the camera. Also included are a mechanism for filtering the output of the shake detecting mechanism, a mechanism for moving the blur correcting optical element based upon the output of the filtering mechanism, and a mechanism for switching the frequency range to be filtered from the output of the shake detecting mechanism by the filtering mechanism before and after activation of the shutter release switch of the camera.
