<p>The present invention provides apparatuses and systems for determining block averages in film grain simulation including determining block averages during a display process and determining block averages during a decoding process. The apparatuses and systems of the present invention exhibit different characteristics in terms of memory requirements and computational cost. More specifically, the first apparatus and system use no external memory, but require either extra reads of the blocks, or internal memory in the display pipeline, while the second apparatus and system require extra memory bandwidth and extra external memory (e.g., RAM).</p> |
