为了提高视频采集的实时性，利用EP2C8Q208C8作为主控芯片来控制CMOS传感器OV7670，采用Verilog语言构建了硬件描述电路。在研究SCCB通信协议的基础上，建立了FPGA和视频采集传感器之间的通信，且对OV7670内部寄存器进行了相关配置，实现在不同模式下视频信号的采集。利用SignalTap II对OV7670视频采集的动态数据进行了实时捕捉，将捕捉波形图对比时序进行了分析。实验结果表明，该视频采集系统除具有低成本、低功耗等优点外，还具有很好的可行性、实时性。

In order to improve the real-time video acquisition.In this design, EP2C8Q208C8 is chosen as the master chip to control the CMOS sensor OV7670. The hardware description circuit is constructed by Verilog language. On the basis of the research SCCB communication protocol,the communication between FPGA and video capture sensor is es-tablished. And the internal register of OV7670 is configured to realize the collection of video signal in different mode. SignalTap II is used to capture the dynamic data about OV7670 video acquisition. A comparison is made between the capture waveform and video acquisition sequence. The experimental results show that the video acquisition system be-sides has the advantages of low cost,low power consumption,also has the very good feasibility,real-time.
