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 Ud0-Ud0 is the charge transfer rate for the previous exposure, and Ud

In a system comprising a passive array of cells arranged in rows and columns for generating pixel information representing a scene, a method for practicing image motion compensation while generating images with said array of cells in a manner so as to compensate for scene topography variations during exposure of said array of cells to radiation from said scene, comprising the steps of: generating first and second images of said scene with said array of cells, said second image generated by said array of cells at a later point in time from the generation of said first image and having associated with it a second image transfer rate U0 to compensate for forward motion of said array relative to said scene; deriving from said first and second images an image correction velocity Ud0-Ud
