A control section causes the image pickup device to perform an AF image pickup operation using exposure value corrected based on the gain correction value, as an exposure value for the AF image pickup operation. The focus detection section performs focus detection based on the image signals of the focus detection pixels in accordance with the AF image pickup operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus adjustment device, focus adjustment method, and non-transitory storage medium for storing focus adjustment programs for performing focus adjustment in response to image signals of an image pickup device including focus detection pixels","description":"A focus detection section performs focus detection based on image signals of focus detection pixels of an image pickup device, included in the image signals acquired based on an exposure value for a l","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10484592","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.
