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.
