An anti-shake apparatus for a photographic device includes an angular velocity detector, a position signal generator, a shake corrector, and an exposure time setter. The angular velocity detector detects the angular velocity of the photographic device. The position signal generator generates position signals representing a position of the photographic device by integrating the angular velocity. The shake corrector corrects a shake of the photographic device, based on the position signals. The exposure time setter sets an exposure time of the photographic device. The shake corrector corrects the shake based on the position signals that have frequencies higher than the predetermined cut-off frequency, which is determined in accordance with the exposure time.
