1. An information processing apparatus comprising: a central processing unit (CPU) operable to: classify a plurality of captured images into a plurality of identical time clusters, wherein an identical time cluster of the plurality of identical time clusters comprises a group of images which are clustered on the basis of date and/or time at which each of the images are captured; extract face regions from the group of images that belong to the identical time cluster of the plurality of identical time clusters; classify the extracted face regions into a plurality of face clusters, wherein a face cluster of the plurality of face clusters comprises face regions of an identical person; generate person information in which persons regarded as the identical person are identified based on the face regions of the identical person which are classified in the face cluster; and integrate a first face cluster of the plurality of face clusters with a second face cluster of the plurality of face clusters, which are not included in an identical image, based on average face feature quantities of the first face cluster and the second face cluster.
