Abstract
Provided is an image shake correction apparatus including: an image taking optical system for taking an image of a subject; an angular velocity detection unit for detecting an angular velocity applied to the apparatus and outputting a first signal; an acceleration detection unit for detecting an acceleration applied to the apparatus and outputting a second signal; an axial rotation angular velocity calculation unit for calculating an axial rotation angular velocity component about a principal point of the image taking optical system based on the first signal; a revolution angular velocity calculation unit for calculating a revolution angular velocity component about the subject based on the second signal and a result of the calculating by the axial rotation angular velocity calculation unit; and a control unit for performing image shake correction control based on a difference between the axial rotation angular velocity component and the revolution angular velocity component.
