Beschreibung
Zusammenfassung:	Provided is a fingerprint authentication device comprising a biometric sensor that senses biometric information to generate a sensing signal; an image processor that extracts a calibration function based on calibration data and generates a fingerprint image based on the calibration function and the sensing signal; and an authenticator that performs fingerprint authentication by comparing the fingerprint image and registered fingerprint information. The calibration data includes information on a calibration coefficient of the calibration function.
