Patent ID: 10592731

Abstract:
A statistical processing is performed without performing complicated determination, so as not to repetitively include the same person. A facial feature extractor (32) in a facial recognition server (30) extracts features of facial image data including a face which is shown in an image obtained by a camera device (10) imaging an imaging area. A preservation unit (35) preserves features of facial image data including a face which has passed through the imaging area, in a pre-passing comparative original facial feature data memory (41). A statistics unit (37) performs statistical processing on the features of the facial image data, which are extracted by the facial feature extractor (32), in a case where feature having high similarity which is obtained by comparison with the features (extracted by the facial feature extractor (32)) of the facial image data imaged by the camera device (10) and is equal to or greater than a predetermined value are not preserved in the pre-passing comparative original facial feature data memory (41) until a predetermined time from an imaging time point by the camera device (10).
