In the conversion table, for directional prediction, a given number of mode numbers in ascending order of the mode number among the mode numbers before conversion are associated with a given number of mode numbers in descending order of the mode number among the mode numbers after conversion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Intra prediction device, image decoding device and program","description":"An intra prediction device performing intra prediction on a luminance block and a chrominance block includes: a chrominance candidate specifier configured to specify a mode number of an intra predicti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997262","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.
