Currently, there are two coding trends in mobile image sensors: Quad Bayer coding (QBC) and dual photodiode (DPD). QBC realizes high resolution and high dynamic range (HDR), whereas DPD achieves high phase detection auto focus (PDAF) performance. We

Rolling-shutter CMOS image sensors (CISs) are widely used [1,2]. However, the distortion of moving subjects remains an unresolved problem, regardless of the speed at which these sensors are operated. It has been reported that by adopting in-pixel ana
