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.
