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.
