A phase difference AF processing unit (19) generates a defocus amount (Df1) from a result of a correlation operation performed with respect to detection signals obtained by adding up detection signals of plural phase difference detection pixels (52A, 52B) in a pair line (PL1) present in a selected AF area (53) and detection signals of phase difference detection pixels (52A, 52B) in pair lines (PL2, PL3) present in a selected direction among plural directions which are crossing directions crossing an X direction with respect to each of the plural phase difference detection pixels (52A, 52B) in the pair line (PL1). A system control unit (11) performs a focusing control based on the defocus amount (Df1)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging device and focusing control method","description":"The present invention provides an imaging device and a focusing control method capable of enhancing accuracy of a focusing control regardless of subjects even when levels of detection signals of phase","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794472","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.
