The image acquisition hardware system designed in this paper,taking DSP and CPLD are as the core,has the functions of the acquisition and quick processing of the digital signal output by image sensor. It is composed of power supply module,DSP peripheral circuit,digital image processing module and CPLD logic control module. It has the merits of small vol-ume,low cost,flexible online programming,perfect real-time processing,etc. It can solve the practical application conflicts among the weight,size,cost,etc. It has the universality for amount of data which is less than 512 K × 8 b. The debugging re-sults show that the image acquisition system achieve the expected goal.%在此设计的以嵌入式DSP和CPLD为核心的图像采集系统，完成了对图像传感器输出的数字信号进行采集并快速处理的功能。主要包括电源模块、DSP外围电路、数字图像处理模块和CPLD逻辑控制模块等。体积较小，成本比较低，在线编程灵活，实时性高的特点是此图像采集处理系统的最大特点，对于嵌入式系统中的经常出现的大小、轻重和成本等在实际中的瓶颈现象可以较好的解决。且文中所设计的便携式图像采集器对512K×8 b以下的容量是通用的。最后的调试实验结果表明，此图像采集系统达到设计的预期目标。
