A 1/2-inch 7.2Mpixel CMOS image sensor with 2.25mum pixels employs a 4-shared pixel structure with pixel-level charge summation. It achieves a 57% fill factor, full well capacity of 14ke- with 41dB maximum SNR at full resolution, 8e-random noise, 15ke-/lux-s sensitivity, and a 3dB increment in SNR for pixel-level charge summation and sub-sampling operation. A 0.13mum Cu process is used
