Abstract
A pattern discriminator receives scanning data obtained by raster scanning objects within predefined window regions with a photoelectric converter, converts the scanned data into pixel binary data by using a threshold value dependent upon the scanning position and window region and evaluates the binary data in accordance with predetermined criteria to produce an output signal indicative of the evaluation. A memory stores data which represents the window regions in a compressed arrangement indicating the ordinate and abscissa coordinates of the beginning and ending points or pixels of each window region location on each scanning line, along with corresponding information representing the particular threshold value to be used for each window region segment on each scanning line.
