The memory and the computer program code are configured, when working with the at least one processor, to cause the apparatus to decode, from a bitstream, quantized transform coefficient data for 16×16 transform unit, and an 8×8 quantization matrix and to inversely quantize the quantized transform coefficient data for 16×16 transform unit using a 16×16 quantization matrix. The 16×16 quantization matrix is set by duplicating at least one of two elements adjacent to each other in the decoded 8×8 quantization matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing device and image processing method","description":"An apparatus includes at least one processor provided with at least one memory that includes computer program code.
