ABSTRACT:
An image stabilization system for maintaining a fixed relationship between target to be photographed and an image of the target as recorded on a photographic film. The system comprises a primary lens system which focuses the image of the target onto first and second optical density wedges, each having a scale of continuous linear density gradations. The wedges are positioned with their respective scales at angles to each other. The light transmitted through the first and second optical density wedges is received by first and second photo-electric cells. The changes in potentials caused by the target movement with respect to the photographic film is received from the photo-electric cells by first and second torquer motors which move a film plate which holds the photographic film in a direction on a given plane corresponding to the target movement.
