Abstract
An image shake correcting apparatus includes a shake detecting unit to detect shake of an apparatus containing an imaging optical system. A calculating unit calculates an image shake correction amount by acquiring a shake detection signal output from the shake detecting unit. A shake correcting unit corrects an image shake in accordance with the image shake correction amount calculated by the calculating unit. The calculating unit calculates an imaging magnification of the imaging optical system, and calculates the image shake correction amount by calculating a first correction amount before change of a frequency range of a correction filter and calculates the image shake correction amount by a second correction amount after change of a frequency range, in accordance with a size of the imaging magnification.
