Thanks to the development of photography camera development , technically speaking , a single lens reflex camera, the film camera technology into a peak. This is a topic to be studied with automatic metering, automatic film , auto exposure function of automatic SLR cameras. Paper first introduces the background of the subject , SLR camera development at home and abroad , the subject to solve problems and to achieve the objectives ; secondly , detailing the camera 's automatic exposure mathematical , physical model (APEX automatic exposure equation ) , Camera hardware, system configuration , features and specifications ; again, a detailed description of the core components - the MCU selection, MCU performance , structure, interface, and power systems to achieve low power consumption , metering mode and metering mode of presentation , automatic measurement optical chip selection and hardware implementation, automatic film chip selection, LCD content, data storage and application of the principle ; Finally, the prototype test results , and a summary of the topics proposed system improvements direction .
