Abstract:
A computer graphics interface for producing an enhanced gray scale image on a monitor having a plurality of separate color inputs. The graphics interface converts at least a first and a second analog signal corresponding to two n-bit digital bytes into a single enhanced signal representative of an x-bit digital byte (where x is greater than n). The interface has an interface input for receiving the analog signals from the computer, a divider for reducing the amplitude of the second analog signal by 2. sup. n to produce an augmented signal, a summer for adding a first of the analog signals and the augmented signal to produce an enhanced signal, and means for conveying the enhanced signal to each of the monitor inputs. This interface is especially useful with a color VGA graphics board where n is 6.
