The clamp processing unit acquires, when information concerning readout is changed, a clamp value predicted from the clamp value before the change and a ratio of charge accumulation times before and after the change, and the readout processing unit performs first signal readout processing after the change with a reference signal clamped by the predicted clamp value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state imaging device and camera system which performs clamp processing","description":"A solid-state imaging device includes: a pixel unit in which pixels that perform photoelectric conversion are arranged in an optical black region and a valid pixel region; a readout processing unit th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537252","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.
