The image processing device encodes an image to generate encoded data, and set, as syntax of the generated encoded data, syntax whose semantics is set so that a default quantization matrix having the same size as a block size that is a unit of processing in which quantization is performed is referred to when in a copy mode in which a quantization matrix is copied, quantization matrix reference data identifying a reference destination of the quantization matrix matches quantization matrix identification data identifying the quantization matrix. The device and method can be applied to an image processing device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing device and method","description":"An image processing device and method that enable suppression of a reduction in coding efficiency.
