Also, in conventional photoelectric conversion devices, techniques for varying the electric signal outputs in real-time at the device level are necessary for real-time import of observation targets or images having a high contrast ratio and for visualization of local areas in real-time. In order to solve this problem, the present invention provides a gain varying method, a variable gain photoelectric conversion device, a photoelectric conversion cell, a photoelectric conversion array, a read-out method thereof, and a circuit therefor in which amplifying photoelectric conversion devices and field-effect transistors are combined."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of varying gain, variable gain photoelectric conversion device, variable gain photoelectric conversion cell, variable gain photoelectric conversion array, method of reading out thereof, and circuit thereof","description":"Expansion of the dynamic range was difficult in conventional amplifying photoelectric conversion devices designed to have a large gain because, when used for high input light intensity, the electric c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641782","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.
