The methods and apparatus generate a frequency-based color shading profile that includes color shading parameters including an amplitude parameter and phase parameter corresponding to hue distributions from experimental shading data and generate an unshaded image by performing color shading correction on the detected color flat areas of the shaded image frame using the color shading parameters."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Content adaptive lens shading correction method and apparatus","description":"Methods and apparatus for providing adaptive lens shading correction in at least a portion of a shaded image frame perform luminance lens shading correction for a portion of the shaded image frame and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11272146","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.
