Information device and display control method
First Claim
1. An information device comprising:
- a fingerprint image capture section which captures a fingerprint image;
a comparison section which compares a first fingerprint image captured by the fingerprint image capture section with a second fingerprint image captured by the fingerprint image capture section at a given time interval after the first fingerprint image is captured;
an image generation section which generates an image based on the comparison result of the comparison section; and
a display section which displays the image generated by the image generation section.

Abstract
In an information device, a fingerprint image capture section captures a fingerprint image of an operator. When a fingerprint image captured by the fingerprint image capture section 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 compares minutiae points of the first and second fingerprint images extracted by a minutiae point extraction section. An image generation section generates image information which is changed while reflecting the comparison results of the comparison section. A display section displays an image based on the image information generated by the image generation section. The information device may be provided with a check section, and display control by the display section may be performed after a fingerprint image is checked by the check section.

12. An information device comprising:
-
a fingerprint image capture section which captures a fingerprint image;
a comparison section which compares a minutiae point of a first fingerprint image captured by the fingerprint image capture section with a minutiae point of a second fingerprint image captured by the fingerprint image capture section at a given time interval after the first fingerprint image is captured;
an image generation section which generates an image, the comparison result of the comparison section causing the image to be scrolled or a pointer on the image to move; and
a display section which displays the image generated by the image generation section.

13. An information device comprising:
-
a fingerprint image capture section which captures a fingerprint image; and
a comparison section which compares a minutiae point of a first fingerprint image captured by the fingerprint image capture section with a minutiae point of a second fingerprint image captured by the fingerprint image capture section at a given time interval after the first fingerprint image is captured, wherein a function of the information device is controlled based on the comparison result of the comparison section. - View Dependent Claims (25)

14. An information device comprising:
-
a fingerprint image capture section which captures a fingerprint image;
a check section which checks registration information which has been previously registered with a first fingerprint image captured by the fingerprint image capture section; and
a comparison section which compares a minutiae point of a first fingerprint image captured by the fingerprint image capture section with a minutiae point of a second fingerprint image captured by the fingerprint image capture section at a given time interval after the first fingerprint image is captured, when the check section has determined that the first fingerprint image is identical with the registration information, wherein a function of the information device is controlled based on the comparison result of the comparison section. - View Dependent Claims (26)

15. A display control method which controls a display section by means of a captured fingerprint image, the display control method comprising:
-
capturing a first fingerprint image and then a second fingerprint image at a given time interval after the capture of the first fingerprint image;
comparing the first and second fingerprint images; and
changing a display image based on the comparison result of the first and second fingerprint images. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 27)
