ROOM ENTRY/EXIT DETECTION DEVICE, ROOM ENTRY/EXIT DETECTION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON

摘要

A person detection unit (211) detects people within an area on one side of a door. An open/closed detection unit (212) detects whether the door is open or closed. A recording unit for open-state person detection information (213) records whether or not the person detection unit (211) detects a person when the state of the door detected by the open/closed detection unit (212) switches from closed to open. A recording unit for closed-state person detection information (214) records whether or not the person detection unit (211) detects a person when the state of the door detected by the open/closed detection unit (212) switches from open to closed. A room entry/exit detection unit (215) detects entry into and exiting from a room on the basis of the details recorded by the recording unit for open-state person detection information (213) and the recording unit for closed-state person detection information (214).
