Abstract
An amount of change between images is calculated based on a motion vector between images obtained by an image sensor and on shake information related to a shake in a rotational direction around at least an axis perpendicular to an optical axis of an imaging optical system. Then, based on a shake correction amount determined based on the shake information and the amount of change, an image obtained by the image sensor is geometrically deformed. The amount of change is a shake component of the image capture apparatus in a direction perpendicular to the optical axis, and is calculated after cancelling at least one of a change between images caused by the shake in the rotational direction included in the shake information and a change between images caused by an influence of a difference between exposure periods of the image sensor.
