Fingerprint identification apparatus and portable electronic device having same
Abstract:
A fingerprint identification apparatus includes at least three light sources, a light guide, a camera module and a processor. The light guide has a top and a bottom surfaces and at least three side surfaces. The top surface serves as a fingerprint contacting surface, each of the side surfaces has a first curved portion, the bottom surface has a second curved portion. Each of the first curved portions is opposite to the respective light sources and configured for converging the light beams emitted from thereof onto the top surface for illuminating a fingerprint thereon. The camera module aligns and cooperates with the second curved portion for capturing and converting an optical image of the fingerprint into electronic image associated with the fingerprint. The processor is configured for receiving and comparing the electronic image associated with the fingerprint with pre-stored electronic images of fingerprints to verify the fingerprint.
