| The development of photography benefited from the development of camera. Technologically, SLR(Single Lens Reflex) camera made the technology of film camera reach a summit. The subject for study is a kind of automatic SLR camera with auto-sensing, auto-winding, and auto-exposure.Firstly, the background of subject, the development situation of SLR in domestic and abroad, the problem to solve and the aim to reach are introduced in the thesis.Secondly, the model of exposure——the APEX(Additive System of Photographic Exposure)is built mathematically in detail. The hardwares, functions and specifications of a SLR camera are described.Thirdly, the choice of CPU, features, configurations and interfaces of H8/38024,the realization of low power consumption, light sense patterns and light sense modes, the realization of auto-sensing, the patterns of auto-exposure, the realization of auto-winding, the display contents of LCD, and the use of I C are detailedly described.Finally, results of sample test are provided, the subject is summarized and an exception to improve the system of SLR is given.
