Abstract
The present invention provides a registration device which can improve the authentication accuracy. The registration device includes a detection means for detecting fluctuation information that fluctuates according to an illumination intensity in an image-pickup element, a filter means for performing the spatial filter processing for an image signal output from the image-pickup element using a filter coefficient which is made to correspond to the fluctuation information detected by the detection means, and extracting a living organism identification subject contained in the image signal, and a registration means for generating registration data from the image signal that is spatially filtered by the filter means, and storing thus generated registration data in a storage medium.
