Claim:
1. An authentication image acquisition device, comprising: an authentication light source, an authentication image acquisition unit, and an authentication image processing unit, wherein said authentication light source irradiates light that contains at least red light in the visible light region toward a palm of a human body, wherein said authentication image acquisition unit comprises a camera that obtains at least one single reflection color image formed by the light which is irradiated from said authentication light source and is reflected from said palm of the human body, and wherein said at least one single reflection color image has RGB (red green blue) pixel values in RGB color space or pixel values in a color space that is convertible into or from RGB color space, wherein said authentication image processing unit performs image processing of said single reflection color image, and thereby extracts a shape of a palm print and a vein pattern in the palm respectively from said single reflection color image for authentication to conduct processing to generate authentication data, and wherein said image processing in said authentication image processing unit comprises, for extracting the vein pattern, processing of signals in the single reflection color image, and wherein said image processing is executed in at least a three dimensional color space used for specifying the single reflection color image, which single reflection color image is also used for extracting the shape of the palm print, and thereby extracting the vein pattern.
