Abstract
A dual lens fingerprint identification method comprises following steps. A first fingerprint image and a second fingerprint image of a finger in contact with a touch panel are captured by a first lens and a second lens respectively. The first fingerprint image and the second fingerprint image are partially overlapped with each other. An image processing procedure is performed to merge the first fingerprint image and the second fingerprint image into a third fingerprint image, and a calculation procedure is performed to compare a plurality of fingerprint characteristic points captured from the third fingerprint image with a plurality of preset characteristic points captured from a preset fingerprint image.
