PROBLEM TO BE SOLVED: To provide a high speed MMR compression device for a binary image. SOLUTION: The image compressor adopting the MMR encoding system consists of a change point extract means 71, a serial/parallel control means 72, a 1st buffer 73, a 2nd reference line buffer 74, an address retrieval means 75 for retrieving changed pixels a1 and a2, an address retrieval means 76 for retrieving changed pixels b1, b2, a means 77 that generates a Huffman code and updates a reference pixel a0, and a packing means 78 for the generated Huffman code.
