Abstract
When verification is performed using a plurality of fingers in accordance with a positional relationship of the joints of the fingers, an image of the plurality of fingers is separated into the images of the respective fingers, and comparison and collation are individually performed for the fingers. Phase data of each finger can be individually extracted, and a collation result of the fingers and phase shift data between the fingers based on phase data are generally determined. A guide member for guiding the placement of the fingers is mounted on a finger table to define positions at which the plurality of fingers are placed.
