Abstract: Overlay or replacement of parts of a monochrome TV picture with corresponding parts of a different picture is accomplished with a new technique using pulsed-light background which enables a silhouette switching pulse to be derived by means of suitable video processing requiring a field-storage delay. This pulse is independent of the tonal range of the subject being overlaid, thus avoiding certain disadvantages of the conventional brightness separation method.
