An image capturing apparatus comprises a shake detection unit configured to detect a shake, a motion vector detection unit configured to detect a motion vector indicating movement of an image from a captured image signal, a motion vector output control unit configured to selectively output an output of the motion vector detection unit and an output of the shake detection unit, a correction amount calculation unit configured to calculate a shake correction amount based on at least one of the output of the motion vector output control unit and the output of the shake detection unit; and a correction unit configured to correct the image blurring of the captured image based on the shake correction amount.
