Partial matching is performed along one coordinates y1, y2 of the searched edge points A-D to calculate the coordinates of the edge points A-D and the positional shift quantity of the pattern is calculated from said coordinates. By feeding back this positional shift quantity, the accurate positional matching of the pattern 6 can be performed.
