AN APPARATUS AND METHOD FOR ENCODING DIGITAL IMAGE DATA IN A LOSSLESS MANNER

A method (900) of losslessly compressing and encoding signals representing image information is claimed. A lossy compressed data file (922) and a residual compressed data file (960) are generated. When the lossy compressed data file and the residual compressed file are combined, a lossless data file...

Zusammenfassung:	A method (900) of losslessly compressing and encoding signals representing image information is claimed. A lossy compressed data file (922) and a residual compressed data file (960) are generated. When the lossy compressed data file and the residual compressed file are combined, a lossless data file that is substantially identical to the original data file is created.
