摘　　要：介绍了金属氧化物半导体图像传感器的基本格式,提出了一种基于可编程逻辑器件的高速数据采集方法,并采用Verilog设计了专用高速图像数据采集控制器,实现了大容量数据采集与存储功能,解决了通用处理器采集速率慢的瓶颈,并省掉了先进先出缓存器,减轻了处理器的运行开销,同时,利用软核NIOSII对图像进行处理和图像显示.实验表明,所提出的方法提高了图像数据采集的速率,并具有更高的灵活性.The basic format CMOS（Complementary Metal-Oxide-Semiconductor） image sensor was introduced, a high-speed data acquisition methods based on FPGA（ Field Programmable Gate Array） was presented, and the special high-speed image data acquisition controller was designed with Verilog language, the high capacity data acquisition and storage function were realized with the controller, and the bottleneck of slow acquisition rate for the general-purpose processor was solved without the FIFO （ First Input First Output） buffer, and this reduced the occupied time by the processor. At the same time, the image was processed and shown with soft-core NIOSII. Experiments showed that the proposed method could improve the image data acquisition rate, and greater flexibility.
