A transmittance changing section changes the transmittance of light that passes through the optically transmissive HMD 208. A shutter control section 220 sets a lower limit value of the light transmittance that can be changed by the transmittance changing section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stereoscopic video observation device and transmittance control method","description":"In a stereoscopic video observation device 200, an optically transmissive HMD 208 presents video observed when a three-dimensional image in a virtual three-dimensional space is projected into a real s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9696548","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.
