基于frame buffer的图像数据采集程序。涉及到framebuffer 、v4l等常用驱动，是个不错的学习材料。-frame buffer based on the image data collection procedures. Related to the framebuffer v4l popular driver is a good learning materials.

此程序是一个通用的摄像头抓图程序，只要在装有linux系统并而己安装有arm-linux-gcc的开发环境下编译即可运行。-This procedure is a generic camera capture process, as long as the installed linux system and has been installed and the arm-linux-gcc compiler development environment to run under.

利用V4L将USB摄像头的采集数据在ARM屏幕上显示,运行通过,效果很好-V4l will use USB camera ARM data collection at the screen, running through, very good!!
