  • Patent number: 4677575
    Abstract: Apparatus for generating figures on a display screen with vector segments being stored in a plurality of picture generators, the apparatus including a segment memory, a decoding unit, a dot memory, an edge memory and a mixer unit. The segment memory transmits a signal representing segment data for all vector segments associated with a given raster line. The decoding unit receives the signal from the segment memory and responds to the same. A determination is made with respect to the edge of a surface and as to whether this edge constitutes an illuminate or extinguish edge. The dot memory stores luminance and color information. The edge memory receives information from the decoding unit and includes circuitry for denoting what picture element is to be activated on a given raster line and the luminance value which has the highest priority with the activated picture element. The mixer unit receives signals from the dot memory and edge memory and forms a complete digital video signal.
