Abstract: A system for detecting the precise location of a reflective element in a video field wherein the determined location is subsequently utilized to generate a graphic to be added to a foreground video scene utilizing compositing techniques. A signal is generated specifying a precise point in the foreground video scene identifying a position of a reflective element. The signal is derived from a peak detector which generates a pulse whenever the signal input to the pulse detector is at a maximum level for the current video field being scanned so long as the scan is not in the blanking area. The pulse is used by a vertical line counter and a horizontal pixel counter which specify the line and pixel on a horizontal scan line within a video field representing the position of the highest peak generated within that field. Graphics can be repositioned or lines or other graphic elements can be generated which track the movement of the reflective element.
