Claim:
1. An information processing apparatus for processing a plurality of images of multiple frames photographed by first and second cameras, the information processing apparatus comprising: a first face detection unit for detecting face areas respectively from a plurality of images of multiple frames photographed by the first camera and slicing the face areas as face images; a first face feature extraction unit for extracting first face feature amounts respectively from the face images; a memory that stores the first face feature amounts; a second face detection unit for detecting face areas respectively from a plurality of images of multiple frames photographed by the second camera and slicing the face areas as face images; a second face feature extraction unit for extracting second face feature amounts respectively from the face images; and a face collation unit for collating the second face feature amounts with the first face feature amounts stored in the memory, wherein the information processing apparatus further comprises at least one of: a first overlap deletion unit for comparing a plurality of face images that have been sliced by the first face detection unit and that have been sliced from different frames to decide whether or not the plurality of face images compared are of a same person; the first overlap deletion unit deleting a portion of multiple face images decided to be of the same person and delivering face images left over without having been deleted to the first face feature amount extraction unit; and a second overlap deletion unit for comparing a plurality of face images that have been sliced by the second face detection unit and that have been sliced from different frames to decide whether or not the plurality of face images compared are of a same person; the second overlap deletion unit deleting a portion of multiple face images decided to be of the same person and delivering face images left over without having been deleted to the second face feature amount extraction unit.
