<p>An interface for controllably reading out color imagery data from a video frame store to a high resolution color monitor, without the need for traversing a communication path through the host computer's signal processing link, includes a programmable color correction mechanism stored in a plurality of look-up table memories, representative of color correction values associated with the primary colors of the video image. When driving the color display with the video image contents of the frame store, the contents of the frame store are read out on a sequential pixel basis and applied as address inputs to the look-up table memories. In response to each frame store imagery data input, each of the look-up tables outputs a color correction code. The three color correction codes that are accessed for each pixel are applied to an analog-digital converter for converting each of the color correction codes into a respective pixel energization signal for controlling the excitation of one of the pixels of the pixel array of the display device, whereby the display device displays the frame store color image in a color-corrected format. The excitation voltage for driving each pixel is derived in accordance with three, eight-bit color correction codes, so that the full color range (sixteen million plus colors) storage capability of the frame store is utilized.</p> |
