Summary:PROBLEM TO BE SOLVED: To provide an indoor monitor system which can find a dangerous state wherein an aged person, etc., becomes unconscious while falling down by distinguishing the posture of a person in a room without invading the privacy in a place wherein the privacy of a person in a room such as a rest room, a bathroom, and bedroom needs to be protected. SOLUTION: A luminescent-point image captured at specific time intervals by an FG view sensor 1 installed on the ceiling surface of a rest room in compared with a previously stored reference luminescent-point image to extract an area where luminescent points move. The feature quantity of this moving luminescent-point area is calculated to distinguish the posture of a person in the rest room, i.e. 'standing', 'sitting', or 'falling down'. When the posture of 'sitting' or 'falling down' lasts exceeding a specific time, a message or voice indicating that this person is in a dangerous state is sent to a portable telephone set that the family bears.
