To provide an image blur correction device capable of surely correcting an image blur with compact constitution even when a magnification factor is high.

The image blur correction device is equipped with: an imaging apparatus having a subject area change means for changing the range of a subject photographed by an imaging optical system; an image blur correction means for actuating a shake correcting optical element constituting a part of the imaging optical system on a plane orthogonal to an optical axis in accordance with the magnitude and the direction of shake exerted on the imaging apparatus; a means for previously storing area data showing relative positional change between the image circle of the imaging optical system and the effective photographing area of an imaging surface when changing the range of the subject by the subject area changing means; and a movable range control means for changing the movable range of the shake correcting optical element corresponding to the change of the subject area based on the area data stored in the storage means in accordance with the operating state of the subject area change means.
