摘要:
An image stabilization apparatus has an angular velocity detector detecting an angular velocity applied thereto and outputting the angular velocity, an acceleration detector detecting an acceleration applied to the image stabilization apparatus and outputting the acceleration, a principal point calculation unit calculating a principal point position of a shooting optical system, an rotation angular velocity calculation unit calculating a rotation angular velocity component about the principal point of the shooting optical system based on an output of the angular velocity detector, a revolution angular velocity calculation unit calculating a revolution angular velocity component about an object based on the output of the acceleration detector and a calculation result of the rotation angular velocity calculation unit and correcting the calculated revolution angular velocity component according to the principal point position, and a controlling unit performing image stabilization control based on a difference between the rotation and corrected revolution angular velocity components.
