摘要： An identification apparatus that keeps the conditions for imaging uniform among successive identifications and requires a user to perform only a series of simple maneuvers. An identification apparatus comprising a guide member, a light source, and an imaging unit. The guide member includes a pattern or a structure that inspires a user to position his/her finger thereon or to approach his/her specific finger region thereto. A contact member such as a button switch is preferably located at a position in the guide member at which a fingertip is to be positioned. An optical opening is formed at a position coincident with a position at which a portion of a finger to be imaged for identification 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.

摘要： A primary object of the present invention is to extract a difference in shading of a blood vessel image in a picked up image as information to be used for authentication, and to acquire a larger number of pieces of biometric information from one image. An individual authentication device to be used to authenticate an individual using feature information of a vascular pattern acquired from a living body includes an imaging unit that images a region of the living body serving as an object of authentication, and an arithmetic unit that acquires the picked up image as an authentication image. The arithmetic unit extracts a vascular pattern from the authentication image, and acquires a degree of shading of the vascular pattern as the feature information.
