The control circuit decreases the time constant after the sampling by the first sample-and-hold circuit ends, and increases the time constant in the middle of the sampling by the second sample-and-hold circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging apparatus and imaging system","description":"An imaging apparatus includes a pixel that generates charge; an integral amplifier that integrates charge transferred from the pixel; a low pass filter to which output of the integral amplifier is sup","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9812474","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.
