Abstract
A personal identification device compares personal identification dictionary data, which is generated from feature data extracted from an identification element for identifying a person and is stored in association with person-specifying information for specifying a person, against feature data extracted from an identification element extracted from a person to thereby identify a person having the captured identification element. The personal identification device includes a dictionary data update processing section that assigns a weighting factor, which is generated from capture time information newly acquired by a time acquiring section and capture time information of an identification element acquired previously and stored in a dictionary-data generating information storing section in association with person-specifying information, to feature data captured at each capture time to thereby generate or update identification dictionary data corresponding to person-specifying information acquired by a person-specifying section on the basis of the result of personal identification.
