摘要： The device of the invention allows the binarized evaluation of a pattern from a signal indicative of intensity values of spatially distributed discrete points of the pattern. It comprises circuits for registering the intensity values of points distributed in at least two concentric rings within an elementary area, at least in one sector centered on the elementary area, determining contrast values each equal to the difference of the registered intensity values between a point of an inner ring and a point of an outer ring, and assigning a positive and negative difference sign to respectively the positive and negative contrast values thus determined having an absolute value higher than a predetermined contrast threshold. A counter is provided for counting distinctively the positive and negative difference signs in the vicinity of the elementary area. An evaluation circuit assigns a light or dark quality to the area respectively when the counted difference signals contain a predominant number of positive or negative difference signs by more than a predetermined minimum.
