A change curve representing a change amount of a focus evaluation value indicating a focusing state of an object image includes a first slope before inversion of a sign of an inclination of the change curve at a peak value on the change curve and a second slope after inversion of a sign of an inclination of the change curve at a peak value on the change curve. The control unit determines whether the focus evaluation value corresponding to the peak value on the change curve is used for the in-focus operation based on an inclination of the first slope and an inclination of the second slope."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus having in-focus operation based on one focus detection area and method for controlling same","description":"An image pickup apparatus includes a focus adjustment unit, an image sensor, a focus evaluation value calculation unit, and a control unit configured to drive the focus adjustment unit based on a focu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667852","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.
