Abstract:
1. A fingerprint identification apparatus, comprising: at least three light sources for emitting light beams; a light guide having a top surface, a bottom surface and at least three side surfaces interconnected between the top surface and the bottom surface, the top surface being a fingerprint contacting surface, each of the at least three side surfaces having a first curved portion provided thereon, the bottom surface having a second curved portion provided thereon, each of the first curved portions, on the respective at least three side surfaces, being opposite to the respective at least three light sources and configured for converging the light beams, emitted from the respective at least three light sources, onto the top surface for illuminating a fingerprint on the top surface; a camera module, in alignment with the second curved portion on the bottom surface of the light guide, configured for capturing and converting an optical image of the fingerprint into an electronic image associated with the fingerprint; and a processor for receiving and comparing the electronic image associated with the fingerprint with pre-stored electronic images of fingerprints to verify the fingerprint.
