感度自動調整機能を有する人工網膜LSI

抄録

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 28dB wider than that of conventional CMOS image sensor. The chip integrates 128×128 pixels whose size is 24×24μm² with 0.8μm single poly-Si and double metal CMOS technology. The chip size is 6.0×4.6mm².
