Abstract
A Digital Video Processing System is provided to process an input digital image, where the video data information of the input digital image includes an undesired noise and a comfort noise. The Digital Video Processing System extracts the input noise which corresponds to both the undesired noise and the comfort noise out of the input image, processes a remaining image, scaling the remaining image to a desired output resolution, extracts the comfort noise from the input noise, processes the comfort noise to regenerate the comfort noise at the desired output resolution, adds the processed comfort noise to the processed remaining image to produce the output digital image at the desired resolution, displays the processed output digital image using an electronic display device, or a region of an electronic display device at the desired output resolution.
