Abstract
A system and method for converting moving video images to a format used by graphics display boards which is based on a pseudo-color method (i.e., displays such as Super VGA used by IBM personal computers and compatibles capable of displaying only 256 colors wherein the resulting visual model emulates thousands of colors displaying richly colored images and delivering a much better result than technologies based on currently used techniques such as the common histogram method. An error factor is determined for each pixel in a frame and a portion of the error is diffused among the neighboring pixels and the corresponding pixel in the next frame. A selection process specifies a universal palette which contains an optimum set of colors for all images, i.e., without using a histogram which determines the colors which appear most frequently in a single particular image.
