Abstract: Faithful color images are created in an efficient manner for display on a specific computer display. A standard computer system generates a palette calibration table, based on information about a standard display. The standard computer system then creates a device independent image from the palette calibration table and from an original image. The palette calibration table and device independent image are then transmitted to a specific computer system. The specific computer system receives the palette calibration table and device independent image from the standard computer system. It calculates a display specific palette from the palette calibration table and from information about the specific display. The specific computer system then generates the faithful color image for display by sending the device independent image and the display specific palette to the display adapter in the specific computer system.
