Method and apparatus for rendering sub-pixel anti-aliased graphics on stripe topology color displays

DETAILED DESCRIPTION It is an object of the present invention to provide an anti-aliasing method and apparatus for use with a stripe topology color display which provides sub-pixel level smoothing in a manner which enhances the apparent resolution of the display, yielding enhanced object shape and positioning, while maintaining accurate foreground and background colors.
The inventive method or apparatus includes the steps or means of: generating a 1 bit per pixel super-sampled bitmap for the image, in which there is greater than or equal to 1 bit for each sub-pixel of the image; determining an average intensity I for each position of the image from the bitmap; determining a sub-pixel intensity S for each sub-pixel using the average intensity I, a foreground intensity F and a background intensity B; and setting a sub-pixel value V for each sub-pixel to produce the sub-pixel intensity on the display.
The method can be implemented via code from a computer-readable medium in a computer system.
