Abstract
An image-blur preventing apparatus includes an image-blur correcting device that is driven in accordance with a subject distance to compensate for the location of an image-blur correcting optical device being located at a position different from a rotational center of the apparatus corresponding to rotational displacement due to a hand shake. The rotational center can be specified at a constant point, and a simple relationship between the needed correction and the subject distance can be established, thereby enabling image-blur prevention.
