摘要
叙述了一种用光电三极管为检测元件，Ａ／Ｄ转换器将模拟信号转换成数字量，单片机为控制运算核心，两个步进电机分别带动可变密度盘和快门开口角，由程序指令进行两个变参数控制的智能型自动调光方法。
This paper discribes a kind of intelligent automatic Light-tuning system which is controlled by a single-chip microprocessor. In this paper,the A/D converter is used. two stepmotors are used to drive the variable density plate and shutter.The variable parameter control is realized by program instructions.
