Abstract

The security camera is widely used. With the long-term aging effect of the environment and the increase in service time, its imaging quality will inevitably decrease. However, there are few research on the impact of environmental aging tests on its imaging quality. This article focuses on the gray scale level of image quality. Considering the complexity of the use environment of the camera, the imaging quality of the typical optical imaging system before and after the gas corrosion testing is analyzed. At the same time, the impact of different light source conditions is also considered here. Studies have found that after environmental testing, the gray scale resolution ability of the imaging system decreases. In addition, light source conditions have a greater impact on its gray scale resolution ability. In the case of optical compensation, the gray scale value is significantly reduced, and the camera cannot perform gray scale resolution. In this paper, two test methods, transmitted standard board method and reflective standard board method, are used to analyze the gray scale value. Studies have found that the results of the two methods are self-consistent.
