摘要
CMOS图像传感器(CIS)相比于CCD图像传感器具有可集成更多功能和集成度以及更小的系统尺寸、重量和功耗及成本(SWa P-C)的优势,CIS技术的最新进步,特别在低读出噪声和高灵敏度的突破,使其不仅达到了相当于CCD图像传感器的图像性能,同时也将其微光使用限定推进到了微光条件,介绍了一种高灵敏度低噪声大动态范围的微光CIS组件,具备从白天到多云残月夜晚的实时单色成像能力,可作为一种在微光成像性能和SWa P-C优选的可见光近红外(VIS-NIR)昼夜成像器件。
CMOS image sensor (CIS), compared with CCD image sensors, has vastly increased functionality and substantial potential for superior integration, low power dissipation and small system size, and recent technology advances, especially the ultra low read noise and superior sensitivity which CIS technology achieved, led to that CMOS image sensor has image performance competitive with CCDs, while the low-light-level CIS is utilized under low light level condition. A low noise high sensitivity and large dynamic range low-light-level CIS camera module for day/night vision is introduced in this paper, which can provide real time digital monochrome video from daylight to cloudy quarter moon night condition (night level 3), and become a perfect cloudy quarter moon night choice of VIS-NIR day/night image device for low-light-level image performance and size, weight and power-cost (SWaP-C).
