The selection unit changes an AF operation for selecting the one focus detecting frame based on the number of low contrast frames to the number of focus detecting frames or based on reliability selected from part of the area and a ratio of focus detecting frames having a high reliability in the area, or performs an AF operation for selecting the one focus detecting frame so that a high contrast frame is prioritized over a low contrast frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control apparatus, image pickup apparatus which changes an autofocus operation based on a ratio of a number of low contrast frames to a number of focus detecting frames","description":"An apparatus includes a calculation unit that calculates a plurality of defocus amounts corresponding to a plurality of focus detecting frames obtained by dividing an area corresponding to a display f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11528406","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.
