摘要：
A system for processing a tracking picture of an intruding object includes a first TV camera for outputting a video signal used for detecting the intruding object, a second TV camera for outputting a video signal used for monitoring a magnified tracking picture of the intruding object, and a picture processing device for processing and operating on the video signal inputted from the first TV camera and outputting a rotation control signal and a zooming control signal. The system detects a difference between the video signal inputted from the first TV camera and a reference background video signal, and a change of a detecting state from the change of the numbers of objects detected in the continuous input video signal.
