The image coding apparatus also includes a basic motion information generating unit 105 generating basic motion information from the decoding information or the coding information selected based on a coding condition indicating a picture type of a current decoded picture to be coded. The coding unit 104 also determines a search range for estimating motion vectors of the current decoded picture, according to the basic motion information, and estimates motion vectors of the current decoded picture in the determined search range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image coding apparatus and method for converting first coded data coded into second coded data based on picture type","description":"Provided is an image coding apparatus including a decoding unit 102 decoding first coded data to generate a decoded picture and decoding information containing motion vectors and including a coding un","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542740","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.
