<p><P>PROBLEM TO BE SOLVED: To provide an appropriate quantization corresponding to a property of an output unit without elongating sign streams. <P>SOLUTION: Compression bitstreams are input into a parser. The parser chooses and outputs all or a portion of the compression bitstreams according to a request. For example, a coded data for displaying a picture on a monitor is output by choosing a coefficient of compressibility of low resolution. Alternatively, a compression data is chosen so that un-losing nature expanssion of an attention region may be made into enable. In one embodiment, the parser, according to a request, outputs a bit required for a variance from a pre-view picture to a printer resolution picture or a full-sized medical monitor picture. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
