Claim:
1. An image shake correcting apparatus that corrects image shake using a first image shake correcting unit and a second image shake correcting unit, the image shake correcting apparatus comprising: a signal separating unit configured to separate a shake signal detected by a shake detecting unit into a low frequency signal and a high frequency signal; and a control unit configured to perform a switching operation between a first control which corrects image shake by controlling the first image shake correcting unit using a shake correction signal calculated from the low frequency signal without the high frequency signal and corrects image shake by controlling the second image shake correcting unit using a shake correction signal calculated from the high frequency signal without the low frequency signal and a second control which corrects image shake by controlling the first image shake correcting unit using the shake correction signal calculated from the high frequency signal without the low frequency signal and corrects image shake by controlling the second image shake correcting unit using the shake correction signal calculated from the low frequency signal without the high frequency signal, wherein the control unit performs the first control if the size of the correctable range of the first image shake correcting unit is larger than the size of the correctable range of the second image shake correcting unit but performs the second control if the size of the correctable range of the second image shake correcting unit is larger than the size of the correctable range of the first image shake correcting unit.
