Display control by means of fingerprint recognition and tracking

摘要

In an information device 10, a fingerprint image capture section 20 captures a fingerprint image of an operator. When a fingerprint image captured by the fingerprint image capture section 20 is referred to as a first fingerprint image and a fingerprint image captured at a given time interval after the first fingerprint image is captured is referred to as a second fingerprint image, a comparison section 30 compares minutiae points of the first and second fingerprint images extracted by a minutiae point extraction section 60. An image generation section 40 generates image information which is changed while reflecting the comparison results of the comparison section 30. A display section 50 displays an image based on the image information generated by the image generation section 40. The information device 10 may be provided with a check section 110, and display control by the display section 50 may be performed after a fingerprint image is checked by the check section 110.
