The camera corrects a value of the defective pixel and a value of one of the first focus detection pixel and the second focus detection pixel that forms the focus detection pixel pair with the defective pixel based on a value of a focus detection pixel of the same type that is not the defective pixel. The camera detects focusing status based on a phase difference between a first focus detection image obtained from the first focus detection pixels and a second focus detection image obtained from the second focus detection pixels after the correction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus detection apparatus and method for controlling the same","description":"A camera has a focus detection sensor that includes a plurality of first focus detection pixels and a plurality of second focus detection pixels, and that has a plurality of focus detection pixel pair","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531560","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.
