A plurality of video image projectors are disposed to be opposed to respective regions of the screen face, and the video image projectors produce a continuous, three-dimensional video image in a circumferential direction, by projecting, from the video image projectors, three-dimensional video images, each of which has an angle of 30 degrees or less in a circumferential direction of the screen face, arranged along the circumferential direction of the screen face."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-dimensional cylindrical video image projecting device and method","description":"A three-dimensional video image projecting device and projecting method uses video image projectors to project a three-dimensional video image on a cylindrical screen face which can be three-dimension","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508583","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.
