Patent ID: 8180119

Claim:
A biometrics authentication system comprising: a microlens array section including a plurality of microlenses, wherein the microlenses are capable of changing a refraction direction of an incident light ray according to an applied voltage; a voltage supplying section for applying a voltage to the microlenses; an image pickup device for receiving light condensed by each microlens in the microlens array section from each different part of a living organism to obtain image pickup data of each part; an image processing section for producing a single image pickup data of the living organism on the basis of the image pickup data of each part captured by the image pickup device; an authentication section for performing at least vein authentication using a vein of the living organism on the basis of the single image pickup data captured by the image processing section; and a control section for controlling the voltage supplying section, wherein when image pickup data for vein authentication using a vein of the living organism is captured, the control section controls a voltage supplied to the microlens array section from the voltage supplying section to be lower than a predetermined voltage value, and when image pickup data for fingerprint authentication using a fingerprint of the living organism is captured, the control section controls the voltage to be higher than the predetermined voltage value.
