Abstract
A read section reads an image. A feature extraction section extracts feature information of a finger, of a person to be authenticated, which is to be collated. The feature information of the finger of the person, which is to be collated, extracted by the feature extraction section is stored in a storage section in advance. A collation section collates feature information of the finger of the person, which is to be collated, extracted by the feature extraction section again, with the feature information read out from the storage section. A control section controls the input operation of the read section on the basis of the collation result obtained by the collation section.
