提出了一种千兆以太网络摄像机的设计,摄像机前端采用SONY CCD ICX285及时序发生器CXD1607和视频ADC AD9945,数字图像处理及千兆以太网接口技术的实现采用TIDSP DM648。时序发生器CXD1607产生时序驱动脉冲,ICX285输出原始的模拟视频信号,模拟视频信号经过视频ADC AD9945处理后,将数字视频信号输出到TI DSP DM648,DM648将接收到的数字视频信号经过处理后通过千兆以太网接口传输给上位机。传输协议采用TCP/IP协议,同时在摄像机上集成了HTTP服务和TELNET服务。
A design of Gigabit Ethernet camera is proposed. The front of the camera adopts SONY CCD ICX285 and timing generator CXD1607 and video ADC AD9945. The implementation of digital image processing and Gigabit Ethernet interface technology adopts TIDSP DM648. The timing generator CXD1607 generates timing drive pulses, the ICX285 outputs the original analog video signal, the analog video signal is processed by the AD9945 video processor and the digital video signal is output to the TI DSP DM648. The DM648 receives the digital video signal after it has been processed Mega Ethernet interface transmission to the host computer. Transmission protocol using TCP / IP protocol, while the camera integrated HTTP service and TELNET services.
