Method of and apparatus for increasing the processing speed in the scanning inspection of circuit boards and other objects

Abstract

Abstract To reduce the large number of pixels resulting from camera scanning of objects in which defects, features or differences are to be detected, and thus enhance process-ing speed, larger pixels are generated composed of groups of the smaller pixels, but with the smaller pixel informa-tion obtained from scanning conveyed by neighborhood majority binary value monitoring to the larger pixels, such that increased data rate is effected through process-ing the larger pixels without, however, loss of defect, feature or difference information contained in the small pixels.
