The imaging system may include processing circuitry that applies a color correction matrix to isolate components of the first and second signals that are generated in response to light of the first and second wavelengths while removing components of the first and second signals that are generated in response to light of other wavelengths. The processing circuitry may increase noise correlations between the signals to mitigate noise amplification generated by the color correction matrix. The processing circuitry may apply a point filter to increase luma fidelity of the signals."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging systems with stacked photodiodes and chroma-luma de-noising","description":"An imaging system may include an image sensor having pixels with stacked photodiodes in which a first photodiode generates a first image signal in response to light of a first wavelength and a second ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9793306","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.
