Abstract: In a fingerprint data registering method, a blurred pseudo image is displayed and, when a fingerprint image for authentication registration is acquired, a fingerprint position of the acquired fingerprint image is extracted. A position in the pseudo image, which corresponds to the extracted fingerprint position, is determined. A part of the blurred pseudo image at the determined corresponding position is converted to a clear partial pseudo-image having a higher resolution than that of the blurred pseudo image and the clear partial pseudo-image is displayed. The acquired fingerprint image is registered as an authentication-purpose fingerprint image in association with the converting and outputting process.
