Abstract
The image shake preventing apparatus can optimally correct image shake according to an image-taking environment and so on, in which a parameter can be changed for a phase correction circuit which corrects a phase shift of an output signal of an angular velocity sensor for detecting vibration of a camera, and a predetermined parameter can be changed which is used for arithmetic processing when angle information is obtained from the output signal of the angular velocity sensor, so that a frequency range where image shake can be effectively corrected for vibration can be changed. An all-frequency mode, a low-frequency mode, and a high-frequency mode can be selected by a mode setting device. A microcomputer sets a parameter corresponding to a selected mode, so that image shake is effectively corrected at 1 to 10 Hz in the all-frequency mode, image shake is usefully corrected at 0.5 to 3 Hz in the low-frequency mode more effectively than the all-frequency mode, and image shake is usefully corrected at 7 to 30 Hz in the high-frequency mode more effectively than the all-frequency mode.
