Abstract
A camera with shake compensation which detects camera shake and cancels image blur on a film exposing aperture due to the shake. The camera is capable of conserving battery power by automatically entering a power saving stand-by mode in which some of the functional blocks of the camera are powered down. The camera includes a selectable shake compensation mode, camera shake detecting circuits, and a control circuit that does not allow the shake detecting circuits from entering stand-by mode whenever the shake compensation mode is active. As a result, the camera is ready to perform shake compensation immediately upon exiting stand-by mode.
