Claim:
1. An image shake correcting apparatus comprising: a first optical correcting unit and a second optical correcting unit configured to correct optically an image shake by using a shake signal output from a shake detecting unit; a first position detecting sensor configured to output a first position detection signal related to a position of the first optical correcting unit; and a controller configured to calculate a first target position signal for controlling the first optical correcting unit based on the shake signal, wherein the first optical correcting unit has a correcting lens and corrects the image shake by relatively moving the correcting lens with respect to an optical axis of an imaging optical system, wherein the second optical correcting unit has a second correcting lens which is different from the correcting lens and corrects the image shake by relatively moving the second correcting lens with respect to the optical axis, and wherein the controller calculates a second target position signal for controlling the second optical correcting unit by using the signal obtained by subtracting the first position detection signal related to the position of the first optical correcting unit controlled by the first target position signal, from the first target position signal.
