FINGERPRINT AUTHENTICATION DEVICE AND CALIBRATION DEVICE AND METHOD THEREOF - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18132262 Titled 'FINGERPRINT AUTHENTICATION DEVICE AND CALIBRATION DEVICE AND METHOD THEREOF'
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 calibration data includes a calibration coefficient that helps in creating an accurate fingerprint image. Finally, an authenticator compares the generated fingerprint image with registered fingerprint information to perform fingerprint authentication.
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.
