Summary: | An identification apparatus keeps the conditions for imaging uniform among successive identifications, and requires a user to perform only a series of simple maneuvers. The apparatus comprises a guide member, a light source, and an imaging unit. The guide member includes a pattern or structure for a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member is located in the guide member where a fingertip is positioned. An optical opening is formed at a position coincident with where a finger to be imaged should be placed. The light source radiates near-infrared light through the portion of the finger to be imaged. The imaging means acquires an image of the finger, and the apparatus compares the image to previously registered images. The apparatus may also include dual light sources power saving functionality, and means for limiting the interference of external light sources. |
