Development of a Wide Dynamic Range Color Camera

Abstract

We have developed a dynamic range extended color camera system using CMD(Charge Moduration Device). The system produces 15 bit dynamic range video signal using two signals at different exposures ; normal exposure signal in a field peirod and short exposure signal using NDRO(Non-Destructive Read Out). Obtaind dynamic range is 16 times as wide as that of conventional camera systems. This proposed method also provides excellent color reproduction.
