Abstract

PURPOSE:To improve the processing speed by suspending the processing in its position, in case one number of discrepancy picture elements has exceeded its threshold level, on the way of a pattern matching processing. CONSTITUTION:A pattern matching circuit 4 is provided with a processing suspending means 4a which sets in advance a thin threshold level SL1 and a thick threshold level SL2 for judging a coincidence or a discrepancy with an object pattern P, with respect to a discrepancy picture element obtained at every dictionary pattern P1, P2, and also, operated, based on these threshold levels. In case one number of discrepancy picture elements has exceeded the threshold levels SL1, SL2 on the way of a pattern matching processing, the pattern matching processing is suspended by the means 4a, and the subsequent processing in its position is not executed. Accordingly, the time required for suspending the processing is shortened, and the processing speed can be improved.
