ABSTRACT:
An image stabilizing apparatus is disclosed which is capable of sufficiently correcting shift shakes even with a small and lightweight accelerometer. The apparatus includes an angular velocity detector which detects angular velocity generated by a shake, an angular velocity computing unit which processes an angular velocity signal, the unit processing the angular velocity signal with a first frequency characteristic, an acceleration detector which detects acceleration generated by the shake, an acceleration computing unit which processes an acceleration signal, the unit processing the acceleration signal with a second frequency characteristic having a signal processing band narrower than the first frequency characteristic, an adder which adds an output signal from the angular velocity computing unit to an output signal from the acceleration computing unit, and an image stabilizing mechanism which performs an image stabilizing operation based on an output signal from the adder.
