Abstract
An imaging processing system (10) for displaying a succession of selected separated images of a moving object (62, 64) moving in an otherwise substantially static scene includes an image sensor (12) for generating video signals of the static scene and for generating video signals of the static scene including the object (62, 64) moving therethrough. The video signals are generated over a plurality of frames (80-94). A first memory (104) stores the video signals of at least one of the plurality of frames from the static scene. A second memory (104) stores the video signals of the plurality of frames from the static scene including the object (62, 64) moving therethrough. Structure (106) is provided for comparing on a frame-by-frame basis the video signals stored in the first memory (104) with the video signals stored in the second memory (104) to thereby determine the presence of the object (62, 64) in each of the plurality of frames (80-90). A display (18) illustrates the location of the object (62, 64) in each of the plurality of frames (80-).
