Abstract
A method and apparatus for color processing of an image displayed on a display device of a computer controlled display system. The method comprises storing the first image and a second image in a first memory; displaying the first image on the display device; displaying the second image on the display device; storing a first color information for the first image in a second memory; storing a second color information for the second image in a third memory; modifying the display of the first image by storing a third color information into the second memory. An example of an apparatus for performing this method includes a frame buffer for storing the first and second image in a computer controlled display device with a processor for controlling the display device. The apparatus further includes a memory for storing the color information, such as a video look-up table. The invention provides a way for modifying the display of one image displayed on a display device without modifying the other image on a display device and without modifying the data in the frame buffer for either image. The invention further provides a plurality of variants of the first image which may be selected to thereby modify the display of the first image according to the variant which was selected. The invention also provides analog controls which are linked to the variants for modifying the first image.
