Abstract

PURPOSE: To enable to perform comparison inspection in excellent manner, by detecting and comparing the boundary line of two dimensional picture toward boundary line with the content of memory and picking up only the boundary line picture present differently among the boundary lines of a plurality of two dimensional pictures.
CONSTITUTION: The inspected picture 2' in which the picture 1' compared and inspected with the reference picture 2 having normal two dimensional picture 1 is drawn, is picked up with the pick up units 4,4' respectively. The two dimensional picture picked up is respectively sampled 5,5' and memorized 7,7' at the memory element located in matrix shape as binary video signal. Further, the boundary line of the two dimensional pictures 1,1' is detected 8,8' toward boundary line direction. The boundary line picture obtained is memorized and compared, and only the boundary line picture existing differently among the boundary lines of two dimensional pictures of a plurality is picked up. Thus, the picture 1' can excellently be compared and inspected.
