Digital image processing method for mobile phone, involves performing Huffman decoding of preset number of coefficients of data unit, so that rest of coefficient is skipped by jumping to next zeroth/first order coefficient in bitstream

摘要

The zeroth order coefficient of each data unit of an image block, is accessed. The Huffman decoding is not performed/performed to preset number of coefficients of data unit, so that the rest of the coefficient is skipped by jumping to next zeroth/first order coefficient in bitstream (36) using information (32) related to number of bits in bitstream between coefficients zeroth/first order in adjacent data unit. Independent claims are also included for the following: (1) image representation format; (2) method for encoding raw image data into compresses digital image representation; (3) method for analyzing JPEG-compressed digital image; and (4) method for stitching two digital images.
