INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM

A information processing apparatus and method is disclosed wherein an image of a predetermined region can be picked up and a desired moving body in the predetermined region can be tracked readily to pick up an image of the moving body. A sensor image acquisition module acquires a sensor image. A moving body detection module detects moving bodies existing in a predetermined region based on the sensor image. A tracking object designation module designates one of the detected moving bodies. When a moving body is designated by the tracking object designation module, an image pickup mode changeover module sets the image pickup mode to a continuous tracking mode in which the designated moving body is tracked to pick up an image of the moving body. The invention can be applied, for example, to a monitoring system.
