摘　　要：设计了一种基于FPGA的超高分辨率SXGA(1280×1024@60Hz)的VGA摄像系统,利用FPGA来控制SDRAM中数据的读写,实现对图像传感器输出的低帧率图像信号插帧到符合VESA标准规定的显示帧率.并且利用FPGA编程的灵活性特点来设计摄像系统,加快了数据处理的速度,节约了硬件上的成本.In this article, an ultra-high-resolution SXGA（1280 × 1024@60Hz） VGA photography system is designed based on the FPGA. Using FPGA, controls in read-write of SDRAM data is realized for the low frame rate image signals which are output to the image sensor to insert the frame in conformity with the VESA standard. Making use of the characteristics of FPGA programming flexibility to design camera systems, the data processing speed can be accelerated, and the hardware costs can thus be reduced.
