摘要
随着数字多媒体技术的不断发展,数字图像处理技术被广泛应用于各种领域。计算机应用领域中,对如此大量的数据进行实时采集和传输的技术难度较大。针对这种情况,设计了基于通用串行总线USB的图像采集系统。利用基于SAA7111的图像转换电路,将CCD图像传感器的PAL信号转换成数字信号;开发了基于EZ-USB FX2的USB2.0接口电路,实现图像数据高速传输;完成了基于FPGA的控制电路,实现对整个系统的控制。
With the development of multimedia, image processing is widely used in various fields. The image data are so large that it＇s difficult to acquire and transmit. So we develop a high speed image transmission system. By using SAA7111 circuit to convert the PAL to digital signal, and Using the USB2.0 interface circuit based on EZ--USB FX2 to transmit data, the system based on FPGA has realized image transmission at high speed.
