Abstract:
1. An anti-shake apparatus for a photographic device, said anti-shake apparatus comprising: an angular velocity detector that detects an angular velocity of said photographic device; a position signal generator that generates position signals representing a position of said photographic device, by integrating said angular velocity; a shake corrector that corrects a shake of said photographic device, based on said position signals; and an exposure time setter that sets an exposure time of said photographic device; wherein said shake corrector corrects said shake based on said position signals that have frequencies higher than a predetermined cut-off frequency that is determined in accordance with said exposure time; and wherein a cut-off frequency selecting operation is always carried out while the photographic device is operating, and when the generation of a subject image is commanded, a cut-off frequency in accordance with the exposure time set at the time is set.
