Abstract:
1. A biometric information processing device, comprising: a placement surface on which a part of a living body whose image is to be picked up is placed; a light source for irradiating said part of the living body with light; an image pickup unit for repeatedly picking up light that has been transmitted from the light source through said part of the living body to obtain a totality of registration image candidates, a part of each of the registration image candidates indicating biological information of the living body, and a difference between at least two of the registration image candidates being a result of a change in position of said part of the living body which is a positional difference of the biological information in a registration image candidate; and a processing unit for processing the totality of registration image candidates to obtain a plurality of registration image candidates that each differ as a result of the change in position of said part of the living body, wherein the processing unit analyzes the plurality of registration image candidates that each differ as a result of the change in position of said part of the living body to calculate a degree of similarity of each of the plurality of registration image candidates with respect to each of the other of the plurality of registration image candidates, wherein the processing unit groups the plurality of registration image candidates into plural groups based on the degree of similarity of each of the registration image candidates within a predetermined range, and wherein the processing unit obtains a registration image from each of the plural groups of registration image candidates.
