The controller controls the focus lens driver so as to prevent the focus lens from being moved for focusing based on a difference between an actual position of the focus lens and the position of the focus lens indicated by the tracking curve in a case the focus lens driver is driving the focus lens based on information on the tracking curve."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical apparatus and drive controlling method","description":"A controller controls a focus lens driver so as to maintain an in-focus state associated with a magnification variation, based on information on a tracking curve that represents a position of the focu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9684225","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.
