| Abstract: | An image acquisition and display system based FPGA and DDR2 SDRAM was designed by using FPGA （Spartan-6 of Xilinx company） as the control chip. The DDR2 SDRAM memory with high bandwidth data and high capacity was able to buffer the real-time data from the OV7670 CMOS image sensor. The realtime image data were displayed on a TFT LCD finally. The result shows that the image acquisition system runs steadily with great imaging quality. |
