<p><P>PROBLEM TO BE SOLVED: To provide a data processing device that reduces the number of computing elements used for wavelet lifting computation and shortens total processing time to the utmost, especially in a data processing device used for two-dimensional discrete wavelet transformation. <P>SOLUTION: The data processing device comprises one or more computing elements for feeding back computation result data on input computational data to perform lifting computation and outputting the computation result data, in a period wherein computational data and computation result data can be once read from and written into a memory respectively. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
