Abstract: A method for recognizing a fake eyeball using lights at two wavelengths comprises the steps of: illuminating simultaneously an eye region with lights at a first and a second wavelength; acquiring a single image of said eye region of said user, by using an imaging device in which R-color sensing elements, G-color sensing elements and B-color sensing elements are arranged; setting an inspection area by specifying a scleral portion, in said single image; calculating a first color average detection amount by averaging the detection amounts of the first color sensing elements at a location corresponding to said inspection area and a second color average detection amount by averaging the detection amounts of the second color sensing elements at the location corresponding to said inspection area; and calculating a ratio between said first and said second color average detection amounts, and comparing said ratio with a predetermined reference ratio.

Abstract: This invention relates to a face recognition system and method capable of updating a registered face template.
