A method for decompressing digital image data to improve the speed of decompression is disclosed. More specifically, the present inventio n 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 examinin g the compressed data and looking for a particular pattern of zero values and/ or and "end of block" statement.
