Document Type and Number:
Japanese Patent JP4344876
Kind Code:
B2
Abstract:
Provided is a biometrics authentication device capable of performing a highly accurate authentication with a simple structure. The biometrics authentication device comprises a plurality of infrared LED arrays provided on the inner wall surface of a chassis and illuminating from directions different from one another, a mirror for reflecting a part or all of a transmitted-light image, a CCD imaging element for simultaneously imaging the transmitted-light image and/or a reflection image of the transmitted-light image created by the mirror, a matching means for performing a matching process between the transmitted-light image imaged by the CCD imaging element and a registered image and extracting an image having the highest matching rate, and a means for deciding, based on the matching rate, whether to authenticate or not. With a simple structure, a blood vessel image can be captured by the transmitted light from a plurality of directions.
