A single ADC is shared by a 2×2 pixels sequentially digitized, enabling optical flow extraction using two-stage deep burst super-resolution framework that incorporates a U-Net-based Quad-Bayer Re-mosaic module, extending the 12MP resolution up to 48MP while providing de-noising, motion compensation. Mobile imaging systems have long relied on rolling-shutter (RS) CMOS image sensors (CISs), which offer compact pixel sizes and high resolution well suited for smartphones
