摘要

研制了一种宽动态范围工作模式的1/2.5英寸、5.2百万像素CMOS图像传感器，并验证了其对高对比度场景图像的有效性。该操作所采用的算法固有地避免了固定模式噪声的产生，而固定模式噪声通常会阻碍量产级宽动态范围图像传感器的实现。所获得的动态范围为96 dB，采用12位输出方案。

A 1/2.5 inch 5.2Mpixel, 96dB Dynamic Range CMOS Image Sensor with Fixed Pattern Noise Free, Double Exposure Time Read-Out Operation

A 1/2.5 inch, 5.2 Mpeixel CMOS image sensor with wide dynamic range operation mode is developed and its effectiveness for high contrast scene pictures is verified. The adopted algorithm for this operation is inherently free from fixed pattern noise generation which often resists the realization of mass production level wide dynamic range image sensors. The attained dynamic range is 96 dB with 12 bit output scheme.
