Abstract
A fingerprint identification method is provided. The method includes steps as follows: having a finger press on a photoelectronic sensor module; respectively emitting an invisible light beam reflected to a photoelectronic sensor module after passing through the finger and a visible light beam reflected to the photoelectronic sensor module via a surface of the finger; generating, by the photoelectronic sensor module, photocurrent signals based on the visible light beam and the invisible light beam; respectively generating, by an analog/digital converter module, a first digital signal and a second digital signal based on the photocurrent signals; and outputting, by a processor module, the first digital signal as a gray-scale fingerprint image and a second digital signal as a colored fingerprint image. The invention also provides a fingerprint identification device performing the fingerprint identification method.
