Abstract:
A method of displaying each of a plurality of images on a digital display unit, each of said plurality of images being encoded in one of a plurality of frames of an analog display signal received by said digital display unit, said digital display unit being included in a computer system, said analog display signal having an associated optimal sampling frequency for sampling said analog display signal, said method comprising the steps of:(a) receiving said analog display signal in said digital display unit;(b) determining whether said optimal sampling frequency is greater than the maximum sampling frequency of an analog to digital converter (ADC) included in said digital display unit;(c) sampling each of said plurality of frames encoded in said analog display signal at a lower sampling frequency than said optimal sampling frequency to generate a plurality of sampled pixel data elements if said optimal sampling frequency is greater than the maximum sampling frequency of an analog to digital converter (ADC) included in said digital display unit;(d) upscaling a smaller image represented by said plurality of sampled pixel data elements to generate an upscaled image, wherein additional pixel data elements are generated based on said plurality of sampled pixel data elements to generate said upscaled image; and(e) displaying said upscaled image on a digital display screen.
