Free,Double Exposure Time Read-Out Operation

A 1/2.5 inch, 5.2Mpeixel CMOS imagesensor with widedynamicrangeoperation mode isdeveloped andits effectiveness forhighcontrast scenepictures isverified. The adopted algorithm forthis operation isinherently free fromfixed pattern noisegeneration whichoften resists therealization of massproduction level widedynamic rangeimagesensors. The attained dynamic rangeis96dBwith12bit output scheme.
