摘　　要：为了满足实际项目需求,设计了一套基于FPGA结合CMOS图像探测器的轻小型彩色数字相机系统。根据项目特点,选用了一片Xilinx公司FPGA作为硬件设计平台,使用Verilog-HDL硬件描述语言并采用自上而下的模块化设计对整个系统进行硬件描述,对图像探测器时序驱动、输出图像格式重组、彩色图像恢复等功能进行了详细的设计。试验结果表明,所设计的图像采集系统在1 280*1 024模式、25 f·s-1的情况下可以实时稳定的实现彩色图像的显示与存储。In order to meet the actual needs of the camera was designed based on FPGA combined engineering project, light and compact real-time digital with CMOS sensor. Based on the characteristics of the system, one Field Programmable Gate Array （FPGA） is chosen as the hardware design platform, and the whole circuit such as sensor timing, image reshaping and demosaicking are described with Verilog-HDL to perform the modularization design from top to bottom. Experimental results show that continuous and realtime 1 280＊ 1 024 resolution data read-out could be achieved at speed 25 f·s^-1.
