说明：  利用Video4Linux内核应用编程接口函数对汽车行驶记录仪中用USB摄像头采集图片的实现进行了开发。基于嵌入式Linux系统的ARM9（EDB9260）平台,对该平台上硬件系统和软件系统的搭建进行简介。配置EDB9260开发商提供的内核（2.6.19），然后具体介绍基于video4linux的USB摄像头图片采集程序的实现,使用autotools来制作Makefile对图像采集程序进行编译。成功的采集到了图片并进行保存，最后完成JPEG压缩的实现。
(Video4Linux kernel application programming interface used on the vehicle traveling data recorder function USB camera capture images using the realization of the development. Based on embedded Linux systems ARM9 (EDB9260) platform, the platform hardware and software systems to build the profile. Configuring the kernel developers EDB9260 (2.6.19), and then the specific description is based on the USB camera image video4linux acquisition program implementation, the use autotools to create Makefile to compile the image acquisition program. Successful collection and save images to finalize implementation of JPEG compression.)
