A quantization parameter calculator derives a quantization parameter of the quantization coding block to be encoded. A prediction quantization parameter derivation unit derives a prediction quantization parameter using the quantization parameters of a plurality of quantization coding blocks which precede the quantization coding block to be encoded in order of encoding. A difference quantization parameter generator derives a difference quantization parameter of the quantization coding block to be encoded, using a difference between the quantization parameter of the quantization coding block to be encoded and the prediction quantization parameter. A first bitstream generator encodes the difference quantization parameter of the quantization coding block to be encoded."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Picture encoding device and picture encoding method","description":"There is provided a picture encoding device that encodes a picture and encodes a difference quantization parameter in a unit of a quantization coding block which is divided from the picture and is a m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10499076","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
