Image stabilizer

The present invention provides an image shake correcting apparatus including a shake signal output device, an image displacing device, and an image shake correcting device, comprising: a pan/tilt detecting device which detects panning or tilting of said optical system; an image shake correction stopping device which stops image shake correction by said image shake correcting device when said panning or tilting has been detected; a pan/tilt end detecting device which detects the end of said panning or tilting; an image shake correction restarting device which causes said image shake correcting device to resume image shake correction when the end of said panning or tilting has been detected; and an object frequency band altering device which raises, for a prescribed length of time after the resumption of said image shake correction, the cutoff frequency on the low frequency side of the frequency band covered by said image shake correction.
