<P>PROBLEM TO BE SOLVED: To reliably specify an eye position even by simple detection with a small amount of calculation by eliminating an erroneous image and different from that of the eye through the use of the small amount of calculation. <P>SOLUTION: An eye position specifying method is the method for specifying an analysis image when the specified part of an eye image is analyzed in order to authenticate an identical person by detecting the center positions and the diameters of a pupil and an iris from an obtained image. When the eye position is specified, the validity in the analysis image is determined. The validity is determined by extracting a plurality of pixels from the areas of the pupil and the iris, so as to measure the luminances (S104, S105), and with a condition of uniformity in the luminances in the areas (S106, S107). <P>COPYRIGHT: (C)2004,JPO |
