Abstract

PURPOSE: To increase a pattern recognition speed by arranging a dot care bit near the tail of dictionary information utilizing the memory region of a dictionary memory, by compressing and storing the dictionary information in the dictionary memory.
CONSTITUTION: In dictionary memory 12, a pair of pieces of information on standard feature pattern D and mask pattern M are stored together and while dictionary information read out from this memory 12 is collated with recognition-objective pattern information extracted from map information holding register 18 and map holding register 19, patterns D and mask patterns M of all "0" or "1" in the dictionary information on memory 12 are erased and compressed information with additional position information of erased patterns. Then, the dictionary information is read out, byte by byte, and on the basis of the additional position information, one-byte data of the dictionary information is applied to collative pattern generating part 22 via regenerative register 14 to generate a collative pattern, so that collation will be made by comparator circuit 23.
