A dictionary memory 14 stores the normal shapes and positions of objects of measurements in quantities as dictionary patterns. Further, a matching circuit 15 reads necessary data out of the memories 13 and 14 and superposes an object pattern and a dictionary pattern one over the other to output the number of mismatching picture elements. Then a CPU 16 receives image data within a constant range from the circuit 12 and measures the length of the cross shape to detect the rough position of the object pattern. Further, a selection instruction for the dictionary pattern is sent to the memory 14 and various instructions required for the pattern matching are sent to and received from the circuit 15 to output the result of the inspection on a CRT 17.
