IMAGE DATA PROCESSING UNIT AND METHOD, RECORDING MEDIUM, AND PROGRAM

摘要: PROBLEM TO BE SOLVED: To provide an image data processing unit that can decode at a low cost with simple configuration. SOLUTION: A classification circuit 83 quantizes quantization DCT coefficients based on representative vector by using code book 82 so as to classify them. prediction coefficient table 84 reads corresponding class and output it product sum arithmetic 85. tap 86 predicts pattern information the extract 81. The 81 extracts outputs 85 conducts operation image.
