Provided is a biometric information processing device which attenuates body movement noise that changes according to the various movement status of a subject and extracts a pulse wave with less noise. This biometric information processing device comprises multiple filters which have different filter properties and which detect a biosignal that includes a pulse wave component and a body movement noise component, detect a body movement signal that correlates to the body movement noise component and separate the pulse wave component and body movement noise component in the biosignal on the basis of the body movement signal, and the device calculates, for each filter, a coefficient of correlation between the body movement signal and at least one of the pulse wave component and body movement noise component, and on the basis of the coefficient of correlation, determines the pulse wave component separated by any one of the filters as a pulse wave signal. According to this biometric information processing device, the pulse wave component in which a noise component is sufficiently attenuated can be selected from the pulse wave components extracted by the multiple filters.La présente invention concerne un dispositif de traitement dinformations biométriques qui atténue le bruit des mouvements du corps qui change en fonction des différents statuts de mouvement dun sujet et extrait une onde de pouls avec moins de bruit. Le dispositif de traitement dinformations biométriques comprend de multiples filtres qui ont différentes propriétés de filtre et qui détectent un signal biologique qui comprend un composant onde de pouls et un composant bruit de mouvement corporel, détectent un signal de mouvement corporel qui est corrélé au composant bruit de mouvement corporel et séparent le composant onde de pouls et le composant bruit de mouvement corporel en le signal biologique sur la base du signal de mouvement corporel, et le dispositif calcule, pour chaque filtre, un coefficient de corr
