Abstract :
A 2.2/3-lnch 4K2K dual resolution and exposure CMOS imager uses motion information to improve the sensitivity by 4 times in comparison to a conventional sensor. The green pixels are read out once every four frames for high sensitivity. Both the red and blue pixels are read out each frame, binned for 2 Ã 2 and used for motion compensation.
