Abstract: An image parallel compression method includes dividing data obtained after a discrete cosine transform (DCT) is performed on raw image data or data obtained after Huffman decoding is performed on image data of a joint photographic experts group (JPEG) format, or the like into several sub-blocks on a block basis, and then performing parallel operations such as intra-frame prediction, and arithmetic coding, to implement image parallel compression.
