Abstract
A reliability extracting section extracts the reliability of positioning at a person's position calculator on the basis of an image captured from an imaging section. A section that creates a possibly-existing area determines a possibly-existing area on the basis of the result of positioning obtained by the person's position calculator and reliability (precision of positioning) obtained by the reliability extracting section. An entry determining section determines entering and/or leaving to/from a targeted monitored area on the basis of the overlapping of the possibly-existing area with the monitored area.
