ABSTRACT:
A biometrics authentication system capable of achieving high precision and high safety is provided. A biometrics authentication system includes: a light source applying light to a living organism; a microlens array section condensing light from the living organism, and including a plurality of microlenses each having a different refractive power; an image pickup device obtaining image pickup data on a plurality of layers of the living organism on the basis of light condensed by the microlens array section; and an authentication section performing authentication of the living organism on the basis of image pickup data on the plurality of layers of the living organism.
