摘要
本文介绍了以MCS- 51 系列单片机为核心的一种照相机性能指标的微机检测系统,它既可单独也可同时检测曝光值偏差△EV、曝光时间T和光圈数F等指标。与传统的单项参数检测仪器相比,该系统具有一机多用,结构简单,成本低廉,不需定期定标,误差小等优点。可供照相机生产厂和商检部门使用。
The paper describes a microcomputer examining system which is used to examine the property of a camera. The system can examine some parameters such as the variation of the exposure △EV,the exposure time T and the aperture F. Compared with the old examining apparatus,the system can be used for various purposes and need not be calibrafed at regular intervals. Its structure is simple and its prime cost is lower. The system can be efficiently used in camera factories.
