摘 要
照相机的测光系统通过测定从被摄物反射回来的光线，计算出可供拍摄时作为参考的曝光组合（光圈和快门的组合），对控制成像效果起着至关重要的作用。经过较长时间的发展，照相机上的测光系统功能日趋齐全，性能也日臻完善。本系统在各方面的原理论证下，对照相机的电子测光系统进行了设计，并使其达到了实际的设计要求。本文主要侧重于对电子测光系统中的设计和运算进行描述。
首先，本文将概述照相机电子测光系统中的基本原理和特点，并且简述电子测光系统。
其次，本文将讲述本系统中的核心——硫化镉（CdS）的基本工作原理，简述硫化镉的要求和实验数据。
最后，本文将阐述电子测光系统的设计和原理。并给出图表说明。讲述电路中部分所用的电子元件的基本工作原理，并会对实验结果进行说明。

关键词：照相，电子测光，硫化镉（CdS）

Abstract camera photometry system reflects the light returning by the admeasurement from the thing
being shot , secretly schemes against out but is for the effect shooting the exposure combination
(diaphragm and the shutter combination) being a reference now and then , controlling imaging face
to face's being playing all-important role. Process more longtime development,upper photometry of
camera system function is day by day all in readiness , the function also becomes more perfect day
by day. And under this system principle demonstration in the field of every, correct camera
electron photometry system has carried out design, have made the person reach actual design demand.
The main body of a book is put particular emphasis on mainly in being in progress to design and
arithmetic in electron photometry system describe that. The primo , the main body of a book will
summarize camera electron photometry system
