Patent ID: 8107689

Claim:
An information processing apparatus for generating a database indicating mapping between characters and the characters' face images, comprising: list generating means for generating a list of characters, appearing in contents data, based on metadata of the contents data; detecting means for detecting a character's face image from the contents data; model generating means for generating a feature quantity model indicating a feature of the detected character's face image; and mapping means for mapping the feature quantity model generated based on the contents data to a character contained in the character list, wherein the mapping means comprises: determining means for determining a target character; retrieval means for searching, in accordance with the character list, the contents data in which the target character appears and retrieving the feature quantity model generated from the searched contents data; determining means for determining a plurality of feature quantity models having a high correlation to each other from among the retrieved feature quantity models; and map generating means for generating a center model serving as a center of the plurality of feature quantity models determined as having the high correlation to each other and mapping the center model to the target character.
