First image data is generated according to a main subject image formed by light from the main subject via a first shooting optical system, and second image data is generated according to a photographer image formed by light from a photographer via a second shooting optical system. First luminance information is obtained based on the first image data, and second luminance information is obtained based on the second image data. According to the first luminance information and the second luminance information, whether or not the main subject is in backlight scene is judged, and based on a result of the judgment, exposure for the main subject is controlled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Exposure control apparatus and method, storage medium, and image pickup apparatus","description":"An exposure control apparatus which is capable of making a backlight judgment with accuracy using image data on a main subject and image data on a photographer and controlling exposure according to th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9781326","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.
