Abstract
In order to meet the demands of high dynamic range for CMOS camera under the mode of global shutter, a camera system is designed based on GSENSE2020S SCMOS image sensor device. By analyzing the readout structure characteristics of pixel of GSENSE2020S chip and the driving timing under the mode of global shutter, we choose ZYNQ with DDR3 as the processing structure and complete the design of SOPC including the control of imaging parameters, driving timing of SCMOS, capturing the image, image preprocessing and SOPC on, and introduces the function of every module. The designed camera realizes the imaging output of 90 frames of 2048×2048 pixel and 12 bit depth with high sensitivity, high dynamic range per second by the imaging test, and it reach the requirement of scientific imaging.
