Claim One:
1. A monitoring camera terminal comprising: an imaging portion for imaging a monitoring target area allocated to an own-terminal; an object extraction portion for processing a frame image imaged by the imaging portion to extract an imaged object; an ID addition portion for adding an ID to the object extracted by the object extraction portion; an object map creation portion for creating, for each object extracted by the object extraction portion, an object map associating the ID added to the object with a coordinate position in the frame image; and a tracing portion for tracing an object in the monitoring target area allocated to the own-terminal using the object maps created by the object map creation portion, wherein the monitoring camera terminal further comprises: a mate-terminal object map acquisition portion for acquiring a mate-terminal object map created by a mate-terminal through data communication with the mate-terminal, the mate-terminal having an monitoring target area allocated thereto, the monitoring target area being partially overlapping with the own-terminal monitoring target area; a coordinate transformation information storage portion for storing coordinate transformation information of the relative position relationship between the coordinate position of the own-terminal frame image and the coordinate position of the mate-terminal frame image; and an identification portion for identifying the own-terminal-extracted object and the mate-terminal-extracted object in the overlapping area where the own-terminal monitoring target area and the mate-terminal monitoring target area are overlapping with each other, and wherein the identification portion uses the coordinate transformation information stored by the coordinate transformation information storage portion to transform the own-terminal-extracted object positions and the mate-terminal-extracted object positions into positions in a common coordinate system, and identifying the objects in the overlapping area using the distance between the own-terminal-extracted objects and the mate-terminal-extracted objects in the common coordinate system.
