An image stabilization apparatus includes an acquisition unit configured to acquire information about a lens, a motion vector detection unit configured to detect a motion vector from a plurality of images captured by an image capture unit for capturing an object image, and a calculation unit configured to calculate an image blur correction amount for correcting an image blur, on the basis of the motion vector detected by the motion vector detection unit, and a shake of an image capturing apparatus detected by a shake detection unit for detecting the shake of the image capturing apparatus. The calculation unit changes weights applied to the motion vector and the shake of the image capturing apparatus for calculation of the image blur correction amount, on the basis of information related to perspective of the lens acquired by the acquisition unit.
