摘要： A color display device which includes dither apparatus for each primary color to be displayed. A dither matrix provides a dither signal output as a function of the position of a pixel on the color display device. An input primary color signal includes an integer signal and a fraction signal. The integer signal is incremented by an incrementer. There is means for providing an output primary color signal which is the incremented signal whenever a predetermined relationship exists between the dither signal and the fraction signal, and which is the integer signal whenever the predetermined relationship does not exist.

摘要： A method for mapping television images onto a graphics screen which can employ a standard digital-television technique to process the television signal is provided. The present invention is concerned with the sampling and storing of a color-television signal in accordance with both the requirements of digital television and the requirements of graphics displays - including windowing requirements - such as used with computers and computer workstations. The invention provides a method of contracting or expanding live color television images, which preferably had been sampled in accordance with a standard digital-television technique, while providing an output of graphics image of a reasonable visual quality for the graphics display.
