发明名称 Method for JPEG decompression
摘要 A method for decompressing digital image data to improve the speed of decompression is disclosed. More specifically, the present invention improves image decompression time by operating upon a subset of the original data and by performing a modified discrete cosine transform on a subset of the originally provided data. The subset is determined by examining the compressed data and looking for a particular pattern of zero values and/or and "end of block" statement. <IMAGE>
