Description
Summary:This paper presents the camera system for increasing sensitivity especially in the low light condition. The camera system consists of two parts. The one is the unique image sensor structure which includes special pixels with broad band spectrum response (White+Near IR) and the other is image processing algorithm which fuses color and White+Near IR (WNIR) information to produce high sensitivity color image. With prototype system we prove the possibility of increasing sensitivity, which is almost 3 times better than conventional RGGB Bayer system.
