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. |
