Abstract
A data compression apparatusand method suitable for image dataassembles pixel valuesinto at least one groupwith a positional index. An encoding unitsets a maximum bit plane according to a highest value in the group, and encodes the data values sequentially along the group using iteratively reduced bit plane levels until reaching a lowest bit plane or exhausting the data values in the group, including recording the positional index where the bit plane level is changed, to provide a compressed dataset.
