发明名称 Method and apparatus for colormapping
摘要 A method for displaying color values in a plurality of images on a display screen in a computer graphics system, wherein the images correspond to a plurality of applications. The graphics system includes a primary frame buffer for pixel values to be displayed in the images, and a plurality of colormap tables related to the images for providing color values to be displayed in the images. A pseudo frame buffer is provided for the applications to store source pixel values for display in the corresponding images. To display the source pixel values in the pseudo frame buffer, for each source pixel the graphics system performs the steps of: identifying the image corresponding to the source pixel value; selecting a colormap table corresponding to the identified image; using the source pixel value as an index to select a color value from the selected colormap table; and storing the selected color value as a pixel value in the primary frame buffer to be displayed. The primary frame buffer may be a pseudo frame buffer implemented in software for providing source data to an HID display through an interconnect.
