ABSTRACT:
The individual identification apparatus includes the image pick up portion 50 and the calculation processing portion 60. When recording information on a specific individual, the portion 50 picks up a pattern of a predetermined body portion of the specific individual and outputs a reference image signal. When desiring to identify an arbitrary person with the specific individual, the portion 50 picks up a pattern of a predetermined body portion of the arbitrary individual and outputs a target image signal. The portion 60 calculates a correlation signal between the reference image signal and the target image signal. That is, the portion 60 digitizes the reference image signal and the target image signal, electronically Fourier transforms those image signals, electronically multiplies the Fourier transformed images, and electronically inverse Fourier transforms the multiplied result to obtain the correlation signal. The portion 60 then judges, based on the correlation signal, whether the arbitrary person is the specific person.
