The system includes, for a second camera, an analogous second face detection unit, a second overlap deletion unit and a second face feature extraction unit. The system includes: a face collation unit for collating the second face feature amounts with the first face values; and a time difference calculation unit for calculating time difference between the first and second shooting time instants. The system further includes at least one of first and second overlap deletion units for comparing a plurality of face images sliced from different frames.
