Abstract
A method for scaling graphics image data. The method operates on data that is in red-green-blue format. Each component is filtered to extract high pass information and then that information is scaled in amplitude. Finally, the amplitude scaled information is recombined with the original components of the image data. The filtering and amplitude scaling sharpen the scaled image, producing a clearer picture.
