摘　　要：介绍一种简单易行的TDICCD自动曝光控制方法,通过对TDICCD工作原理的介绍、对其驱动时序的分析来说明了采用FPGA实现TDICCD自动曝光控制的原理。并采用VHDL对所设计的驱动时序进行编程,针对ALTERA公司可编程逻辑器件EP2S60F484C3ES进行适配,在QUARTUS5.0下进行仿真。系统测试结果表明,设计的CCD驱动程序可以满足TDICCD的各项驱动要求,并且达到了自动曝光的目的。To introduce a method of TDICCD automatic exposure,according to the explanation of TDICCD work principle and the analysing of TDICCD driving schedules,the achievement of TDICCD automatic exposure based on FPGA is illuminated. Driving schedule generator has been described with VHDL. The designed generator has been successfully fulfilled system simulation with QUARTUS5.0 software and fitted into EP2S60F484C3ES（ a kind of FPGA products that made by Ahera）. Experiments show that designed generator is suitable for the driving of TDICCD, and fulfilled automatic exposure.
