In this case, the setting unit sets a position of the first region based on information regarding at least one of a position, a size, and a direction of the predetermined subject in the image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus detection apparatus and control method therefor","description":"A focus detection apparatus includes an image pickup unit configured to perform photoelectric conversion on a luminous flux having passed through an imaging optical system, a focus detection unit conf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10516821","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.
