Abstract
A method and apparatus for optimizing the storage of compressed images includes serially storing pixel block data in memory. Fixed memory utilization can be improved for images having pixel blocks of varying information content. A cumulative memory allocation is updated during processing of each pixel block and compared with the current memory requirement. Memory not utilized for earlier processed pixel blocks having low information content can be used to store later processed high information content pixel blocks.
