The unit pixels are driven to set the potential of a potential barrier at a boundary between the memory and the floating diffusion region to a potential such that a charge overflowing the memory is transferred to the floating diffusion region, when the first transfer gate is turned on. The CMOS image sensor operates in a global shutter mode for capturing moving images."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state image pickup device in which charges overflowing a memory during a charge transfer period are directed to a floating diffusion and method of driving same","description":"A CMOS image sensor has an image array as a matrix of unit pixels each including at least a photodiode, a memory for holding a charge stored in the photodiode, a floating diffusion region for converti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9749557","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.
