APPARATUS AND METHOD FOR ENCODING DIGITAL IMAGE DATA IN A LOSSLESS MANNER |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To make lossless compression without reducing compression efficiency. <P>SOLUTION: A method of losslessly compressing and encoding signals representing image information is claimed. A lossy compressed data file and a residual compressed data file are generated. When the lossy compressed data file and the residual compressed data file are combined, a lossless data file that is substantially identical to the original data file is created. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
