摘要
一种以AD9847+FPGA为核心架构的CCD成像系统。分析了AD9847及其在系统中所发挥的重要作用。针对目前模拟前端一般采用专用CCD视频信号处理器来实现的方案,给出视频图像预处理和白平衡算法的硬件实现流程。最后对AD9847的PCB布局布线进行了分析和设计。实践结果表明,像素速率37.125MHz时,系统性能较好。
A CCD imaging system which has an architecture of AD9847 plus FPGA is presented. AD9847 and its important function are analyzed. Thus, based on the design scheme of a specified CCD video signal processor, the hardware processing procedure of image pre-processing and white balance algorithm is introduced. In the end, the layout and PCB routing about AD9847 are analyzed and designed. The result shows that, the system performs perfectly with pixel rate of 37.125 MHz.
