Further, margin parts are generated in the correction images in a manner so that parts defining the correction points in the correction images are projected within the projection area while the parts defining correction points in the correction images corresponding to the projection units that are next to each other are overlapped."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projection system, image processing apparatus, and correction method","description":"A projection system includes projection units collectively projecting an image as a whole on a projection area; a generation unit generating correction images including correction points which are use","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9818377","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.
