IMAGE PROCESSING SYSTEM, IMAGE PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To suppress increase in a code amount when the number of quantization matrixes becomes large.SOLUTION: The image processing system includes an inverse quantization section 240, for dequantizing quantized data calculated by quantizing transformation coefficient data generated by orthogonally transforming image data in a transformation unit of 16×16 by using a quantization matrix of 16×16 having a style formed by copying a first element or a second element mutually neighboring in a quantization matrix of 8×8 as an element between the first element and the second element.SELECTED DRAWING: Figure 9
