Real-Time Auto-Light System for High-Speed Camera

Abstract:

In order to obtain stable and high quality image from high-speed camera in real time under different environment, the system hardware based on TMS320DM642 is designed and a complex control method is proposed to realize auto-light control rapidly by harmonizing alterable diaphragm and camera exposure time. The algorithm of the auto-light system mainly consists of two parts: the analysis of brightness information based on Variance weighted information entropy, camera exposure time control and alterable diaphragm control based on data analysis. The project results show that the algorithm has rapid convergence and strong adaptability, and the system can realize large-scale and real-time auto-light at different conditions.
