A method to increase DR using column-level automatic gain selection
semanticscholar(2017)
摘要
Introduction In this paper we present an image sensor with a very high linear dynamic range that is obtained by combining a pixel with using three level transfer gate method and a column-level automatic gain selection. The automatic gain selection (AGS) picks one out of three linear ranges each having a largely different conversion gain. The data rate remains the same as without high dynamic range, thus preserving the maximal frame rate.
