A frequency and a characteristic point of a change in the amount of light of flicker are detected based on an image signal read out from an image pickup device. Based on the frequency detected at first timing before continuous shooting is performed and the characteristic point detected at second timing later than the first timing during continuous shooting, a characteristic point of a change in the amount of light of flicker after the second timing is predicted. Timing of light exposure is controlled so as to be coincident with the characteristic point after the second timing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus that reduces unevenness of exposure caused by artificial light source, method of detecting change in amount of light, and storage medium","description":"An image pickup apparatus which is capable of, when performing continuous shooting at high shutter speed under an artificial light source with varying amounts of light, reducing the effects of a chang","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9716840","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.
