Abstract:
1. An image blur correction apparatus comprising: a shake detection unit which detects a shake; a calculation unit which calculates an image blur correction amount that is data for correcting an image blur which is caused by the shake and is obtained by integrating output signal of said shake detection unit that is speed data detected by said shake detection unit by an integration unit; an image blur correction unit which corrects the image blur based on the image blur correction amount calculated by said calculation unit; a shake level determination unit which determines a shake level of an image capturing apparatus based on an output of said shake detection unit; a subtraction unit which subtracts an offset value, which is speed data for returning said image blur correction unit to a center of a movable range of said image blur correction unit, from speed data output from said shake detection unit; and a changing unit which changes the offset value based on the image blur correction amount and the shake level.
