An image stabilization apparatus comprises: a first obtaining unit that obtains orientation information of an image capturing apparatus; a determining unit that, on the basis of the orientation information, determines a reference position of an image sensor included in the image capturing apparatus; and a calculating unit that calculates a correction amount for performing image stabilization by moving a position of the image sensor from the reference position in a plane intersecting with an optical axis. The reference position is different between when the orientation information indicates that the image capturing apparatus is in a first orientation and when the orientation information indicates that the image capturing apparatus is in a second orientation.
