Guidance screen control method of biometrics authentication device, biometrics authentication device, and program for same
First Claim
1. A biometrics authentication device, which captures an image of a body part, detects biometrics characteristic data from said captured image for biometrics individual authentication, comprising:
- an image capture device which captures an image of said body part;
a display device which displays screens to guide a user in operating said image capture device; and
a control unit which performs image capture operation of said image capture device, detects said biometrics characteristic data from captured images of said body part for biometrics authentification, and wherein said control unit judges, from the output of image capture operations of said image capture device, whether said image capture has been successful, temporarily stores the cause of an unsuccessful image capture, and, when image capture is not successful even after image capture operation of said image capture device a prescribed number of times, analyzes said temporarily stored causes, and displays a guidance screen on said display device according to the results of said analysis.

Abstract
In a biometrics authentication device which uses biometrics information to authenticate individuals, guidance is provided such that image capture of biometrics information is performed appropriately. An image capture device is caused to perform a plurality of image capture operations (including distance measurement) at short intervals. And when image capture NG occurs frequently, a control unit stacks the NG results, and if image capture NGs are not resolved even after a prescribed number of image capture operations, judges that the relation between the body part and the image capture device must be corrected, analyzes the stacked image capture NG causes, and displays a guidance screen on a display device according to the analysis result.
