A flicker component is detected using the luminance information of the image signal in the extracted flicker detection region. A correction value to correct the flicker component is generated from the detected flicker component. This makes it possible to accurately correct, using a simple arrangement, a flicker component contained in an image sensed under a light source whose brightness periodically changes even when the object or the image sensing apparatus moves."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flicker correction apparatus, flicker correction method and image sensing apparatus","description":"A flicker detection region in which an image signal has values relating to luminance and colors within predetermined ranges is extracted from a plurality of flicker detection regions allocated in the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471923","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.
