CMOS PRNU dataset

In order to accurately measure non-uniform noise, it is necessary to suppress the influence of experimental environment errors and other noise sources in the imaging system. We conducted imaging experiments in a darkroom environment, where we illuminated the diffuse reflective panel with an adjustable xenon lamp to produce a uniformly adjustable light source. The CMOS image system is located within 30 ° of the normal of the reflector to capture images. It can be assumed that all pixels receive the same intensity of light. At the same time, set the light intensity to over 50% of the CMOS saturation brightness to reduce the impact of CMOS dark current.为精准测量非均匀噪声，需抑制成像系统中实验环境误差与其他噪声源的影响。我们在暗室环境中开展成像实验：使用可调氙灯照射漫反射板，以生成均匀可调的光源。CMOS图像系统（CMOS Image System）位于反射面法线30°范围内以捕获图像，此时可认为所有像素接收到的光强一致。同时将光强设置为CMOS饱和亮度的50%以上，以降低CMOS暗电流的影响。
