<P>PROBLEM TO BE SOLVED: To accurately specify a sensed area by a human body sensor to be displayed on an image, in an image monitoring device including the human body sensor which sets a part of monitored space by an image as sensed space. <P>SOLUTION: An image monitoring sensor executes: a step for conducting a walk test within monitored space to measure a characteristic 150 of a sensing signal level of a human body sensor corresponding to a human image position within an image; a step for using the characteristic 150 to extract a sensed position distribution range Ro that contains the human image position for which the sensing signal level is equal to or greater than a reference level Z1 of human body sensing; a step for setting an allowable level Z2 of human body sensing, which is lower than Z1; a step for obtaining a correction distribution range Re resulting from correction to expand the range Ro so as to contain the human image position which is present within a range of distance B on both sides of the range Ro and for which the sensing signal level is equal to or greater than Z2; and a step for setting a sensed area so as to center the range Re. <P>COPYRIGHT: (C)2012,JPO&INPIT |
