The second range is set so as to include the first range. In a case where the second range is detected by the contrast detection as being in an in-focus state, a control unit changes a control mode into a predetermined control mode in which the driving of the focus lens is limited according to the defocus information in the first range detected by the phase difference detection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic focus adjustment apparatus and control method therefor","description":"In an automatic focus adjustment apparatus, a setting unit sets, on an image sensor, a first range in which defocus information is detected using a phase difference detection and a second range in whi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742985","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.
