ABSTRACT:
An electro-optical imaging array provides compensation for image motion due to variations in scene terrain electronically and with no moving parts. Pixel information representing scene information is transferred through the array in column groups. Each column group has its own charge transfer rate U. Successive images of the scene are generated by the imaging array, and the images are correlated by electronic signal processing circuitry to determine the image displacement of a fixed point in the scene between successive images. The image displacement is used to calculate a residual image velocity U.sub..delta. in each column group. As successive images of the scene are generated, the charge transfer rates U for each column group are updated, whereby U=U.sub.0 -U.sub..delta., where U.sub.0 is the charge transfer rate for the previous exposure, and U.sub..delta. is the residual image velocity in each column group.
