Review of current developments and trends of CMOS image sensors

With the development of VLSI, CMOS image sensor has developed increasingly. The history of CMOS image sensor was introduced, on the basis of analyzing the principle of CCD and CMOS image sensor, the advantages of CMOS image sensor was summarized. The current research status and commercial productions of different companies were described in this paper, moreover, the technical specifications were presented. At last, the current applications and trends of CMOS image sensor was focused.
