  • Video signal processing apparatus for separating an image of a moving object from video signals
    Patent number: 4805018
    Abstract: In a video signal processing apparatus, a contour signal of a moving object is separated from static background video image signals. The video signal photographed by a television camera is converted into a binary contour signal. One converted signal obtained at a certain time and another converted signal obtained at another time are processed to extract a contour signal of the moving object. The extracted contour signal of the moving object is supplied to a circuit which controls panning and/or tilting of the television camera.
