1. A dual lens fingerprint identification method, comprising steps of: using a first lens to capture a first fingerprint image of a finger in contact with a touch panel and using a second lens to capture a second fingerprint image of the finger in contact with the touch panel, wherein the first fingerprint image and the second fingerprint image are partially overlapped with each other; and performing an image processing procedure to merge the first fingerprint image and the second fingerprint image into a third fingerprint image, and performing a calculation procedure 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.
