A video signal is processed as a series of sequential line signals by a number of cascaded processing stages. A correlator 13 compares the video signal with reference data after it has passed through an initial processor stage 6 - 11. The arrangement is organised to process a large amount of data rapidly, with data from a particular stage being processed while data representing different line signals of the same video signals is being processed by a preceding or following stage. The video signal may represent a scene viewed by camera 6 and the reference data represents the expected scene (or a part) as the camera moves along an expected path. <IMAGE> |
