摘要： A system for processing a tracking picture of an intruding object includes a TV camera (2) provided with an imaging lens (1) of a wide field of view for outputting a video signal used for detecting the intruding object, a TV camera (17) provided with a zoom lens (16) for outputting a video signal used for monitoring a magnified tracking picture of the intruding object, the TV camera mounted on an electric pan head (18), a picture processing device (3) for processing and operating the video signal inputted from the TV camera provided with the imaging lens of the wide field of view and outputting a rotation control signal for rotating the electric pan head by a necessary amount of angle and a zooming control signal for zooming the zoom lens by a necessary amount. The system images the object intruding into a given monitoring area while automatically tracking it with the zoom lens. Further, the method executed in the system includes step (101, 102, 103) of detecting a difference between the video signal inputted from the TV camera and a reference background video signal, step (104, 105) of classifying a change of a detecting state from the change of the numbers of objects detected in the continuous input video signal, step (106) of creating and saving as connecting information a location of detected object at each time, area of a region occupied by the detected object, a pixel pattern of the detected object from the change of the detection state, and step (107, 110 to 116) of correcting the detection location of the object detected as a split state and a trace of objects detected as a connected state.
