MONITOR SYSTEM, CAMERA AND VIDEO IMAGE CODING METHOD

摘要

A monitor system is provided for making it possible to efficiently determine a coding quantity of each camera in accordance with the movement of an object. In each camera (101) composing the monitor system, based on a position of the object detected by a sensor (106) and position specifying information of neighboring cameras and cooperation parameters stored at a neighboring camera information memory unit (405), (1) a distribution pattern indicative of a distribution of values of the cooperation parameter in a space where a plurality of the cameras exist forms a concentric circle defined from the object as a starting point, and (2) a cooperation parameter renewal unit (413) for renewing the cooperation parameters so that a target coding quantity of the camera, which picks up an image of the object, can be larger than a target quantity of the camera, which has not picked up an image of the object, and the camera is provided with a target coding quantity determining unit (410) for determining the target coding quantity allocated to its own camera based on the cooperation parameters of the neighboring camera and the target coding quantity stored at the neighboring camera information memory unit (405).
