Abstract
Provided is an image shake correcting apparatus including an angular velocity sensor. A frequency separating unit separates a shake detection signal into a low frequency signal and a high frequency signal by filtering. A first image shake correcting unit performs image shake correction based on one signal of the high frequency signal and the low frequency signal and a second image shake correcting unit performs image shake correction based on the other signal. A frequency separation control unit determines the image shake correcting units to which the low frequency signal and the high frequency signal are respectively applied depending on the zoom position of the optical system of an imaging apparatus. The frequency separation control unit prohibits a change of control of the frequency separating unit during a zoom position change operation but changes control of the frequency separating unit after completion of the zoom position change operation.
