Abstract
An extended field of view image memory has x-y coordinates corresponding to the sight area of an extended field of view image, and a depth corresponding to the maximum number of elemental image pixels that can be compounded to form a pixel of the extended field of view image. Each elemental image is entered into the memory in registration with a previously acquired elemental image, and pushes down any previously entered images it overlaps. The finite depth of the memory thus forms a FIFO register at each pixel location, which eliminates the oldest pixel data when a newly entered image causes the maximum pixel depth at a location to be exceeded.
