camara driver for s3c2440 under linux

linux下通过V4L2的接口调用camera，获取数据。保存成YUV和RGB文件。可以通过YUV和RGB工具查看是否获取数据正常与否。可以在ubuntu中，切换成framebuffer，申请一块内存使其显示在屏幕。-in linux,with v4l2 interface,open camera and obtain data buffer.we can save data buffer with yuv or rgb.such as rawview tools,check data buff

基于V4L2框架的camera图像抓取，并转换成可视的格式，便于理解v4l2框架(Camera image capture based on V4L2)

V4L2摄像头采集接口程序，并且在ARM9上LCD显示成功(V4L2 camera acquisition interface program, and on ARM9, LCD shows success.)

用摄像头采集图像数据，然后将数据发给对应得服务器，可以实现网络视频监控。(We can use camera to collect image data, and then send data to the corresponding server, so that we can achieve network video surveillance.)
