  • Publication number: 20140146172
    Abstract: Provided is a distributed image processing system for detecting an object located in a monitoring target area and an attribute of the object. An area terminal processes an image captured by a video camera, and detects whether the object of which the image is captured is present. When detecting the object located in the monitoring target area, the area terminal focuses an image capturing visual field of a digital still camera on the detected object, and inputs a release signal to the digital still camera. The area terminal transmits a still image captured by the digital still camera to a server through a network. The server processes the still image transmitted from the area terminal, and detects an attribute such as a kind and a size of the object of which the image is captured. The server performs an output according to a detection result of the object located in the monitoring target area.
