Digital display system with color lookup table |
摘要 |
A digital display system includes a frame buffer store containing picture element data which is read out to address a color lookup table from which color data is read to a display device. The color lookup table comprises a first area storing color data common to a plurality of images and further areas each storing color data related to a corresponding one of the images. Data in the first area is generated by uniformly sampling a color space, data in the further areas is generated by sampling and quantizing input image data.
