A method for modulating color for effecting color cell texture

摘要

A full color real time cell texture generator uses a quantization scheme, preferably a tapered quantization scheme (402-412), which establishes a small set of colors representative of all colors of a source image. A source image to be displayed is quantized (414) by selecting the color of the small set nearest the color of the source image for each cell of the source image. Nearness can be measured as Euclidian distance in a three-space coordinate system of the primary colors: red, green and blue. In a specific embodiment, an 8-bit modulation code is used to control each of the red, green, blue and translucency content of each display pixel, thereby permitting independent modulation for each of the colors forming the display image.
