Image distortion correction system for electro-optic sensors
First Claim
1. An image correction system for providing a view of a scene scanned by an electro-optic framing sensor, which includes control means operable to cause the sensor to scan the scene in a number of separate frames each of which is viewed at a different viewing angle relative to a set of datum axes, pickoff means associated with the sensor to produce signals representing the viewing angle of each frame, storage means operable to store the image information derived from each of same frames, circuit means operable to transform the image information contained in each storage means so as to remove distortions caused by the different viewing angles, and a picture store operable to store the transformed image information from each frame of the scan such that the contents of the picture store represent a view of the scene from a predetermined viewing angle.

Abstract
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.
