摘要：This paper analyzes the exposure control principle in the process of aerial photography. Acquiring the optimum exposure is a key to improvethe image quality of photography. The method of using differential brigh.tness measurement and mean differential brightness controlexposure has been advanced through analyzing the strong and weak points of various exposure light measuring methods and by means ofsensor filter and microcomputer, The affected factors of all related aspects, the different mathematical models of calculation and exposurecontrol or the method of calculation, diagram have been analysed, which provides the way for realizing this system
