ABSTRACT:
A palette device for use with circuitry that produces color codes and a video control signal. The palette device includes a mode circuit establishing one of a plurality of different operating modes, and color code processing circuitry operable according to a mode established by the mode circuit and responsive to the color codes to supply color data words that are convertible to analog form. Depending on the different modes, the color code processing circuitry establishes different time intervals between input of the color codes to the color code processing circuitry and supplying of color data words. A digital to analog converter connected to said color code processing circuitry receives the color data words and converts them to an analog video signal. A variable delay circuit responsive to said mode circuit delays the video control signal by a time interval depending on the mode established by the mode circuit, and the variable delay circuit is connected to control the digital to analog converter with the video control signal thus delayed. Palette devices, computer graphics systems, facsimile systems, printer systems and methods are disclosed.
