Abstract:
1. A method of rendering anti-aliased foreground text on a graphical image background comprising the steps of: providing an anti-aliased foreground textual signal and a background graphic image signal; correlating a location on a display device with a pixel from each of a foreground textual image and a background graphical image; determining a pixel color component maximum characteristic for each pixel in the anti-aliased foreground textual image and providing a report of such pixel color component maximum characteristic to a background image signal modifying block; subtracting from each pixel color component in a background graphic image an amount equal to the pixel color component maximum characteristic for the corresponding pixel in the anti-aliased foreground textual image and thereby creating a selectively augmented background image; wherein said selectively augmented background image is a pixel by pixel selectively dimmed image; adding the anti-aliased foreground textual image to the selectively augmented background images on a pixel color component basis, thereby creating a combined and augmented image; and driving a display device with the combined and augmented image.
