The specular reflection decision unit performs a threshold determination regarding the count of pixels or the proportion of pixels exhibiting a received-light quantity of a predetermined proportion or greater with respect to the maximum received-light quantity among received-light quantities from the reflected light and decides that the reflected light is specularly-reflected light when the count of the pixels or the proportion of the pixels is a predetermined threshold or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Person-detecting sensor and automatic water faucet","description":"A person-detecting sensor includes: a range-finding unit that decides whether distance to a detection object falls within a predetermined detection distance range; and a specular reflection decision u","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9664791","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.
