ABSTRACT:
An optical system compensating apparatus comprising an image sensing element for converting an optical image formed by a photographic optical system into an electrical signal, a variation detecting circuit receptive of the image signal from the image sensing means for detecting a temporal variation of the image for each picture, and a drive system for driving the photographic optical system on the basis of the detection result of the variation detecting circuit so that the temporal variation of the image becomes smaller, thereby automatically compensating for the shake of the image, wherein a judgment circuit is provided for judging whether or not the temporal variation of the picture is a monotonous increase or a monotonous decrease in a certain direction from the detection result of the variation detecting circuit, so that the drive system is controlled in accordance with the judgment result.
