Since the amount of a reduced upper ray L1 of oblique luminous flux and the amount of a reduced lower ray L2 thereof are made to be substantially equal to each other by the first APD filter and the second APD filter, a deviation of a blurred image is reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lens barrel, imaging device body, and imaging device","description":"There are provided a lens barrel, an imaging device body, and an imaging device that can reduce a deviation in a blurred image of oblique luminous flux caused by an APD filter.A lens barrel includes a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838592","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.
