PROBLEM TO BE SOLVED: To suppress an increase in amount of codes due to an increase in number of quantization matrices.SOLUTION: Provided is an image processing device including: a selection section configured to select, from a plurality of transform units with different sizes, a transform unit used for orthogonal transformation of image data; a setting section configured to, when a 16×16 transform unit is selected by the selection section, set a 16×16 quantization matrix by duplicating a first element or a second element adjacent to each other in a 8×8 quantization matrix as an element between the first element and the second element; and a quantization section configured to quantize transform coefficient data, which is generated by orthogonally transforming the image data on the basis of the 16×16 transform unit selected by the selection section, by using the 16×16 quantization matrix set by the selection section. |
