Abstract

High dynamic range (HDR) in spatio-temporally oversampled single photon counting image sensors, such as the Quanta Image Sensor (QIS), is achieved by combining different pixel exposures. In this paper, the HDR techniques applicable to QIS are described. A SPAD-based QIS is employed, with dual global shutters and in-pixel memories, as the first proof of principle demonstrating extended or high dynamic range in a QIS.
