1. A biometrics authentication system comprising:

  • a light source configured to apply light to a living organism;

    a microlens array section configured to condense light received from the living organism, the microlens array section including a plurality of microlenses, each microlens of the plurality of microlenses having a different refractive power;

    an image pickup device configured to obtain image pickup data of the living organism based on light condensed by the microlens array section;

    a rotation angle determining section configured to determine a rotation angle of the living organism based on the image pickup data of the living organism;

    a three-dimensional information producing section configured to produce three-dimensional information of the living organism based on the image pickup data of the living organism; and

    an authentication section that performs authentication based on the rotation angle determined by the rotation angle determining section and the three-dimensional information produced by the three-dimensional information producing section.
