The lens calculator sends the second correction information to the image capturing apparatus in a case where the lens calculator performs the interpolation process and sends the first correction information to the image capturing apparatus in a case where the image capturing apparatus performs the interpolation process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lens apparatus and image capturing apparatus","description":"The interchangeable lens apparatus includes a memory to store first correction information to be used to correct focus state information on a focus state of its image capturing optical system, the foc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9674420","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.
