摘　　要：为了实现数字图像的高分辨率实时处理,以CYPRESS公司生产的高性能CMOS图像传感器LUPA-4000为研究对象,设计了一种基于FPGA和串口通信控制的大面阵CMOS相机系统。详细介绍了系统的整体结构及电路设计,结合CMOS图像传感器的工作模式和驱动时序,以FPGA为主控单元,实现了图像驱动电路及存储电路。测试结果表明,设计的相机系统方案合理,与计算机通信正常,系统运行稳定可靠,安装光学系统后获取了高质量图像,图像分辨率为2048×2048。For achieving the high resolution real- time processing of the digital image, using high-performance CMOS image sensor LUPA- 4000 produced by CYPRESS company as the key component, a kind of large plane CMOS camera system was designed, based on FPGA and serial communication controller. The overall structure and circuit design were described. Combined with the CMOS image sensor’s timing sequence and working mode, the sensor driving circuit and image data memory circuit were implemented with FPGA. Experiments demonstrated that the designed camera system was reasonable. The whole system run steadily and reliably. The communication with computer was exact. Image with high quality had been taken after installing optical system, and the resolution of the image could be achieved 2 048í2 048 pixels.
