Claim 13:
14. An authentication apparatus, comprising:
an imaging unit which is arranged at a position opposed to a plurality of palm surfaces of fingers to be presented, and is configured to image the plurality of fingers;
a first light source which is arranged at a first position in a first array direction of the plurality of the fingers, and is configured to irradiate the palm surfaces and a first side surface of each of the fingers with light;
a second light source which is arranged at a second position in a second array direction of the plurality of the fingers, and is configured to irradiate the palm surfaces and a second side surface of each of the fingers with light;
an image processing module configured to generate image data of the plurality of fingers based on an output signal from the imaging unit; and
an authentication module configured to authenticate the plurality of fingers based on first image data of the plurality of fingers generated by the image processing module, and second image data of the plurality of fingers generated by the image processing module;
wherein a first optical axis of the first light source is tilted in a direction where the second light source is present, and a second optical axis of the second light source is tilted in a direction where the first light source is present.
