Moving subject detecting apparatus and the method

摘要

Response pattern extracting unit 220 extracts absence detection response patterns including moving subject responses to be judged and presence detection response patterns that have symmetrical time component structures to these absence detection response patterns based on moving subject responses of moving subject detecting sensor 110 (at least one moving subject detecting sensor 110 is placed in respective rooms). Leaving room response pattern determining unit 230 adds flags showing leaving room response pattern to the above-mentioned absence detection response pattern when a response pattern extracted in response pattern extracting unit 220 includes a pair of time components that are in time reversal correlation with each other and practically equal to each other. Leaving room judging unit 240 refers to leaving room response pattern determining unit 830, the unit checks whether a flag showing a leaving room response pattern is added to the absence detection response pattern to be judged, and judges that someone left the room when receiving an absence detection response pattern to be judged from response pattern extracting unit 220.
