The motion vector search unit sets a plurality of block types for each encoding block, performs rough motion vector search using a reduced image for each block type, computes an evaluation value for each block type based on the motion vectors, and determines whether to set a division method of the block type for which the highest evaluation value was obtained as a motion compensation block division method for a motion vector search in detail."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Moving image encoding apparatus and moving image encoding method","description":"A moving image encoding apparatus comprises a motion vector search unit for dividing a screen into encoding blocks, dividing each encoding block into motion compensation blocks, and performing a motio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488678","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.
