A detection system detects moving objects in a scene by processing two consecutive images of the scene. The two consecutive images are captured by a pan-tilt-zoom (PTZ) camera and fed back to the system. The system obtains position information of the moving object in the scene, and adjusts parameters, such as a shoot angle, and a focal length of the PTZ camera, according to the position information of the moving object. Therefore, the PTZ camera can be aimed to follow the motion area and adjusted to optimum focal length. |
