Abstract
A processing device for air/ground reconnaissance using optronic equipment of high performance. A high speed detection matrix and a particular electronic processing of video signals is used to reconstruct a scan image from elementary images which have a high degree of overlap and are offset due to scan residual. For example, an incident light beam is projected in the direction of a line of sight through an optical system. Video signals are transmitted to a digital circuit to supply luminance values of successive elementary images to two image memories. A correlation processor delivers an offset signal for the current image to an image reconstruction processor which also receives luminance values for the current images. An image patch memory is reconstructed in which the elementary images are realigned.
