Paper Abstract

Low light level (LLL) imaging mainly relies on to detect weak night sky of targets reflecting, and environmental illumination is one of the important factors affecting the LLL image features. Germany's third-generation image intensifiers, Toshiba Terry company CS8620Ci types of CCD device as the main core to build LLL image acquisition experimental system, and LLL images are collected in a dark room with different illumination. This paper analyzes relationship between the statistical properties of the LLL image non-target area and environmental illumination, studies the laws between the mean, variance, autocorrelation, variance of sum and environmental illumination. And these laws based on experimental data were fitted to obtained specific mathematical expressions.
