FIELD OVERLAPPING DEVICE FOR A COLOUR VIDEO PRINTER GIVING PERSPECTIVE REPRESENTATIONS

摘要

A overlapping device of a color video printer for overlapping arbitrary two-field video signals on a single screen is disclosed. In this device, one field video signal between the selected two-field video signals is used with its original density and the video signal corresponding to the other field is used as a background screen by controlling the color density of the video signal by changing the digital value of the video signal by the shift register, thereby giving a perspective representation.
