Abstract
A human retina like, wide operating-range CMOS image sensor with pixels that shift their intensity-response curves according to the intensity of light has been constructed. The chip realizes an operating range 29dB wider than that of conventional CMOS image sensor. The chip integrates 128×128 pixels whose size is 24×24μm^2 with 0.8 μm single poly-Si and double metal CMOS technology. The chip size is 6.0×4.6mm^2.
