ABSTRACT:
A vibration correction system in a camera which detects vibration of the camera caused, e.g., by a hand tremor, and corrects for the vibration of an image in an image plane caused by vibration of the camera. The vibration correction system includes a vibration sensor which detects vibration of the camera, and a vibration correction optical system which is driven to correct for the detected vibration. When an anomaly occurs in the vibration detection sensor, in the vibration correction optical system, or in the drive system of the vibration correction optical system, the operation of the vibration correction optical system is inhibited. The vibration correction optical system also adjusts for correction error resulting from chatter in a gear mechanism of the drive system of the vibration correction optical system by controlling shutter timing. The vibration correction optical system further adjusts for correction error resulting from a delay in the output of the vibration detection sensor by controlling shutter timing in order to minimize the error caused by the delay.
