<p><P>PROBLEM TO BE SOLVED: To shorten a time required until restoration of a still image is started by enabling efficient decompression processing of compressed image data, in a still image data decompressing device. <P>SOLUTION: A variable length decoding part 211 and an inverse quantizing part 212 performs the variable length decoding and inverse quantization of compressed image data, and the hierarchical DCT factor of each block forming a still image is written in a memory 206. A factor/pixel value converting part 213 performs L3-L1 decoding using the DCT factor of each hierarchy stored in the memory 206 in parallel with writing of the DCT factor in the memory part 206. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
