CMOS image sensors is important for mobile phone cameras. But, when very small pixel sizes are used, the sensor SNR is limited by photon shot noise. In order to improve the sensor SNR Honda and Luo proposed the use of a sensor with a white (W) pixel in the color filter area. The white pixel, however, saturates at low light levels and sufficient dynamic range cannot be obtained as a result. In order to overcome the dynamic range problem, we propose a CIS with a WRGB color filter array (two white pixels per 2x2 block) incorporating the wide dynamic-range (WDR) technology.
