1. A biometrics authentication device comprising:

  • a filter that extracts a plurality of directional features from an input image;

    a per-direction directional feature normalization processing unit that normalizes, by a computer, the plurality of directional features so as to make a luminance value that corresponds to a palm print smaller than a luminance value that corresponds to a vein;

    a non-directional feature generating unit that generates, by the computer, a non-directional feature on the basis of the plurality of directional features output from the per-direction directional feature normalization processing unit;

    a matching processing unit that determines, by the computer, a degree of similarity between the non-directional feature and a registered non-directional feature stored in a storing unit; and

    a determining unit that determines, by the computer, identity by using the degree of similarity.
