Simplified Explanation

The abstract describes a fingerprint authentication device that uses a biometric sensor to capture biometric information. This information is then processed by an image processor, which uses calibration data to generate a fingerprint image. The device also includes an authenticator that compares the generated fingerprint image with registered fingerprint information to perform fingerprint authentication. The calibration data includes a calibration coefficient that helps in generating an accurate fingerprint image.


Original Abstract Submitted

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.
