Abstract:

This paper introduces the realization of a web camera supporting the  B/S(Browser/Server) pattern based on S3C2440 CPU and the mjpgstreamer software. The basic hardware structure consists of the S3C2440 which is the main processor of the network camera, the camera with USB interfaces and the DM9000 net chip, which is used to take and transmit pictures. The uboot and Linux are used as the bootloader and the embedded operation system respectively in the software system. The mjpgstreamer is the software to manage picture stream, which focuses more on the method of compiling, function and porting. In the end, the function by which the  realtime video pictures taken by distant network cameras can be watched through a browser is realized.
