Apparatus and method for compression of image data

A data compression apparatus and method suitable for image data assembles pixel values into plural groups. An encoding unit sets 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 re...

description	A data compression apparatus and method suitable for image data assembles pixel values into plural groups. An encoding unit sets 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, to provide a compressed dataset. Examples include recording a positional index where the bit plane level is changed within each group.
