<p>A pattern image processing apparatus for collating image data of a finger read by a reader with previously registered feature data derived from the finger to verify the identity of a person, wherein light emitted from a light source (12) is radiated on a finger (10), and light reflected by the finger (10) is sensed by a camera (13). The finger image sensed by the camera (13) is converted to a digital signal and is sequentially added by an adder (15A) in a direction perpendicular to the longitudinal direction of the finger, thus generating finger feature data P2(j). The generated feature data P2(j) is compared with the previously registered feature data P1(i) which was similarly generated and stored in a memory (18A). When a coincidence is found between these data, the person's identity is verified and a door (20) is opened. When a coincidence is not found, the person's identity is not verified, and the door (20) is not opened.</p> |
