Abstract

A detecting system for detecting a deviation of a camera from shaking has at least two shaking detectors and one correcting device. The first shaking detector detects a camera shaking corresponding to one axis of a camera coordinate system. The second shaking detector detects a camera shaking corresponding to another axis of the camera coordinate system. The correcting device only adjusts a device corresponding to the first shaking detector in an optical system when a maximum or minimum value is detected on the output signal from the second shaking detector.
