摘　　要：文章介绍基于高速线性CCD器件的图像采集系统的构成及其应用。通过对CCD图像传感器TCD1209D驱动时序及数模转换芯片AD9224的转换时序的分析,结合图像采集系统硬件功能要求,设计用于图像采集的高速线性CCD驱动电路,并采用单片复杂可编程逻辑器件(CPLD)进行了实现;测试表明驱动时序产生电路满足目标图像采集系统的应用需要。In this paper, an image acquisition system, which is based on the high-speed linear CCD, is introduced. The driving timing of the CCD image sensor TCD1209D and the conversion timing of the analog-to-digital converter AD9224 are analyzed, and the circuit that creates the driving signals to drive the linear high-speed CCD is designed. The driving circuit is implemented by the single complex programmable logic device （CPLD）, which meets the application needs of the image acquisition system.
