Abstract
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.
Claims9
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.
A photographic device comprising:
- an angular velocity detector that detects an angular velocity of said photographic device;
- a shake corrector that corrects a shake of said photographic device, based on said angular velocity;
- and
- an exposure time setter that sets an exposure time of said photographic device;
- wherein a component of said shake that said shake corrector can correct 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.
