Abstract: An “accumulation buffer” process in a graphics processing system is carried out not by rendering each sub-frame making up the accumulated frame in its entirety in turn, but by subjecting each individual tile 2, 3, 4 and 5 making up the accumulated frame to the sequence of different rendering passes individually. Thus, for each individual tile making up the accumulated frame, several sub-tiles (e.g. 2?, 2?, 2?? and 2??) are generated in turn and accumulated together to provide a final accumulation tile (2ACC) that is output as the accumulated version of the tile in question. This is then repeated for each of the remaining individual tiles 3, 4 and 5 making up the accumulated frame 1, and the individual accumulated tiles 2ACC, 3ACC, 4ACC and 5ACC are combined together to provide the output accumulated frame 6.
