ABSTRACT IMAGE CORRECTION SYSTEM A system for providing a view of a scene scanned by an electro-optic framing sensor (30) includes control means (36) operable to cause the sensor to scan the scene in a number of frames each of which is viewed at a different viewing angle. Pickoff means (37) provide signals representing that viewing angle. Storage means (32) are provided to store the image information derived from each frame. Circuit means 33 are provided to transform the image information in each store (32) so as to remove distortions due to the different viewing angles, and the transformed image information is stored in a picture store (34). The contents of the picture store represent a view of the scene as viewed from a predetermined viewing angle.
