Abstract
The present invention provides a fingerprint recognition apparatus and a fingerprint recognition method adapted for the apparatus. The method includes steps of: performing an image processing function for fingerprints of a user and generating an image formed by a number of ridges; scanning the image according to a scanning frequency and selecting a number of scanning lines; acquiring a cross point formed between each ridge of fingerprint and each scanning line; acquiring a tangent line; generating a graph between each cross point and each corresponding slope value; determining whether the graph is similar to one of the stored at least one graph to obtain a determination result; and outputting a recognition result of the fingerprints of the user associated with the determination result.
