<p><P>PROBLEM TO BE SOLVED: To provide a bit modeling computing element used in the case of configuring an image coder adopting the JPEG 2000 coding system or the like that can attain high speed bit modeling processing with a simple configuration. <P>SOLUTION: A path computing element 26 sequentially carries out determining processing of a path for each bit in a bit plane by using 4 bits of a stripe for a path determining processing unit. Then a context computing element 28 uses 4 bits of the stripe for context determining processing unit and carries out the context determining processing of each bit of the bit plane by using a symbol, path information and significant information obtained by the path computing element 26 to carry out the context determining processing of 4 bits of the stripe. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
