A control unit is configured to obtain defocus information corresponding to the area using the first defocus information and the second defocus information, and to perform focus control based on the obtained defocus information. The first region has a length longer in a phase-difference detection direction than the length of the second region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus control apparatus and control method therefor","description":"An acquisition unit is configured to acquire first defocus information based on a sensor output corresponding to a first region in an area of a captured image, and to acquire second defocus informatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742980","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.
