A dual in-pixel memory CMOS image sensor for computation photography

We present a new image sensor to help applications like high-dynamic range, structured illumination, motion corrected photography, etc. by providing two analog memories in each pixel. Clever pixel design allowed us to create the smallest pixel size and the largest fill factor for this class of imager, while supporting dual global shutter operation and true correlated double sampling (CDS) readout from both in-pixel memories to cancel kTC noise.
