Abstract
A graphics system comprising a format processor for receiving display data including pixel data and color-blending information for at least two (2) separate display layers, a color blender and color processors. The pixel data includes color information for the display layers. The color-blending information determines weighting factors for use in blending the colors of the display layers. The format processor outputs separate streams of pixel data, one for each display layer, as well as the weighting factors. Each stream of pixel data outputted by the processor is inputted into a corresponding color processor that assigns colors to a particular display layer according to the color information in the corresponding pixel data. The color blender blends the colors assigned to the display layers according to the weighting factors.
