means for obtaining and calculating a degree of correlation
between image information of said at least one reference point and
image information of each point in said detection area;

representing the degree of correlation in a rectangular
correlation table, the plurality of said numerical values being
arranged in a one-to-one correspondence with respect to each point
in the detection area;

alternately and repeatedly; and
decision means for deciding a coincidence between the image
