Abstract
The image pick up portion 50 picks up a pattern of a predetermined body portion of a specific individual a plurality of times and outputs a plurality of reference image signals for being stored. The image pick up portion 50 also picks up a pattern of the predetermined body portion of an arbitrary individual desired to be identified with the specific individual and outputs a target image signal. The calculation processing portion 60 electronically performs a Fourier transform on the plurality of reference image signals and the target image signal. The calculation processing portion 60 superimposes the Fourier transformed results of the plurality of reference image signals. The calculation processing portion electronically multiplies the thus superimposed reference image signals with the Fourier transformed target image signal. The calculation processing portion electronically performs an inverse Fourier transform on the multiplied results to thereby obtain a similarity degree between the reference image signals and the target image signal, thereby judging whether or not the arbitrary individual is the specific individual.
