Abstract

An electro-optical imaging array (32) having pixels arranged in rows and columns electronically compensates for image motion in the plane of the array regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of row and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft (22) about roll (R), pitch (PI) and/or yaw (Y) angles in addition to forward velocity (V) of the aircraft (22). The image motion compensation is achieved with no moving parts and does not require a stabilized platform. The pixel information in the array (32) is transferred in the row and column direction in a step-wise fashion in the row and column directions at a rate and direction substantially matching the image motion.
