PROBLEM TO BE SOLVED: To reduce a calculation amount by performing accurate image shake correction without causing breakdown in control even if angular vibration and parallel vibration are mixed in any state. SOLUTION: An image shake correction apparatus including an image taking optical system 102 for photographing an image of a subject includes: an angular velocity detection unit 130 for detecting an angular velocity applied to the image shake correction apparatus and outputting the angular velocity; an acceleration detection unit 121 for detecting acceleration applied to the image shake correction apparatus and outputting the acceleration; an axial rotation angular velocity calculation unit 301 for calculating an axial rotation angular velocity component about a principal point of the image photographing optical system based on an output of the angular velocity detection unit; a revolution angular velocity calculation unit 304 for calculating a revolution angular velocity component of the center of an object to be photographed based on the output of the acceleration detection unit and a result of the calculation by the axial rotation angular velocity calculation unit; and a control unit 108 for performing image shake correction control based on a difference between the axial rotation angular velocity component and the revolution angular velocity component.
