Abstract

A method of decompressing a set of subsampled image data is disclosed. The method includes reading a first subset of the subsampled image data into a cache memory and into a buffer, wherein the buffer has an amount of memory equal to or less than the cache memory, calculating chrominance values for at least some pixels of the subset of the subsampled image data to form decompressed image data, and outputting the decompressed image data.
