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, wherein the first lens comprises a first angle formed between a first optical axis of the first lens and a surface of the touch panel, and the second lens comprises a second angle formed between a second optical axis of the second lens and the surface, wherein at least one of the first angle and the second angle is between 40 degrees and 85 degrees.
