Abstract:
A method for improving image quality in a graphics pipeline on a per-pixel basis, comprising;(a) identifying a previous frame and a current frame each including a first field and a second field; (b) identifying a first pixel value of a pixel in one of the fields of the previous frame, and a second pixel value of a corresponding pixel in a corresponding one of the fields of the current frame; (c) determining whether a difference between the first pixel value and the second pixel value exceeds a predetermined threshold; and (d) if the difference exceeds the predetermined threshold, outputting a pixel of the current frame that is altered to improve output picture quality; wherein if the difference exceeds the predetermined threshold, merging a pixel of the first field of the current frame with the corresponding pixel of the second field of the current frame that is altered to improve output picture quality; wherein if the difference does not exceed the predetermined threshold, merging a pixel of the first field of the current frame with a corresponding pixel of the second field of the current frame that is left unaltered; wherein the pixel of the second field of the current frame is altered by combining a pixel value of the pixel of the second field of the current frame with a pixel value of a corresponding pixel of the second field of the previous frame.
