The factor of limiting dynamic range of CMOS image sensor is analyzed. And dynamic range extension technique used currently is introduced. For the issues existing in using multiple exposure and multi-slope integration, a new method called multiple multi-slope integration is proposed. Based on camera system of LUPA1300-2 image sensor, experiment and analysis indicate that multiple multi-slope integration improves the quality of imaging effectively.
