The present invention provides a technology capable of simply performing individual authentication with high accuracy by extracting the feature of the vein pattern and the feature of the palm print shape of the person to be authenticated from a single original image data photographed using a visible light image acquisition unit (e.g. visible light camera).
An authentication light source 11 radiates light which contains at least red light in the visible light region toward a palm of a human body. An authentication image acquisition unit 12 acquires at least one reflection image formed by the light which is radiated from the authentication light source 11, and is reflected by the palm of human body. An authentication image processing unit 13 performs image processing of the reflected image, and extracts the shape of palm print and the shape of veins in the palm respectively from a single sheet of the reflected image for the authentication to generate the authentication data. |
