Abstract:
1. A non-contact biometrics authentication device, comprising: an image capture device, which captures, without contact, images of a body part; a display device, which displays an image guiding operation of the image capture device for a user; and a control unit, which performs image capture operation of the image capture device, detects biometrics characteristic data from the captured images of the body part, and verifies the biometrics characteristic data against registered biometrics characteristic data, wherein the control unit detects, a plurality of times, positions of the body part using an output of the image capture operation of the image capture device performed a plurality of times, calculates a movement velocity of the body part from the positions captured the plurality of times, calculates a predict position of the body part at the time of output of a message according to a final position of the positions captured the plurality of times and the movement velocity, calculates acceleration from the movement velocity, judges prediction precision of the predict position from the acceleration, decides a guidance message according to the predict position and the prediction precision, and displays the guidance message on the display device.
