The readout circuit includes an amplifier unit configured to amplify the signal from the pixel, and have a variable gain, and a hold capacitance connected to an output terminal of the amplifier unit via a sampling switch, and having a variable capacitance value. When the variable gain of the amplifier unit is set to be a first gain, the variable capacitance value of the hold capacitance is set to be a first capacitance value. When the variable gain is set to be a second gain larger than the first gain, the variable capacitance value is set to be a second capacitance value smaller than the first capacitance value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image capturing apparatus and image capturing system with variable gain","description":"An image capturing apparatus includes: plural pixels arranged in matrix, each outputting a signal from a photoelectric conversion element; and plural readout circuits each provided for a corresponding","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9661249","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.
