Abstract

A fingerprint authentication device includes a biometric sensor configured to generate a sensing signal by sensing biometric information, an image processor configured to generate a fingerprint image based on the sensing signal, a singular point determiner circuit configured to select at least one fingerprint piece based on the fingerprint image or the sensing signal, and determine a singular point of the fingerprint image by analyzing the selected at least one fingerprint piece, and an authenticator circuit. The image processor is further configured to extract an interest region including the singular point from the fingerprint image based on a coordinate of the singular point, and the authenticator circuit is configured to perform fingerprint authentication by comparing the interest region with registered fingerprint information.
