Abstract: An apparatus, system and method is provided to determine a motion of pixels in local regions of a scene, classify the motion into a speed category, and make decisions on how to render blocks of pixels. In one implementation the motion in a tile is classified into at least three different speed regimes. If the pixels in a tile are in a quasi-static speed regime, a determination is made whether or not to reuse a fraction of pixels from the previous frame. If the pixels are determined to be in a high speed regime, a decision is made whether or not a sampling rate may be reduced.

Abstract: In a graphics system regions of a frame are analyzed to determine local regions of the frame in which adaptive desampling may be performed. In one implementation a standard sampling scheme includes at least one sample per pixel and regions that are adaptively desampled have one sample for a block of pixels having a size of at least four pixels. A level of detail map is generating to identify regions in which desampling may be performed. The level of detail map may be based on detecting motion, detecting an edge, and detecting a content frequency.
