The the second imaging section is disposed in a position closer to the optical axis of the projection lens than the first imaging section. The control section causes the first imaging section to capture an image in a case where the distance from the projector to the projection surface is greater than or equal to a predetermined threshold and the second imaging section to capture an image in a case where the distance is smaller than the threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector","description":"A projector includes a projection lens, a distance information acquiring section that acquires distance information relating to the distance from the projector to a projection surface, a first imaging","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9843781","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.
