USAGE:
1.First，you must make your minigui support jpeg.If you have no experiences,you can refer to http://www.hhcn.org/maindoc/USB_Camera_base_on_Video4Linux.pdf 基于Video4Linux 的USB 摄像头图像采集实现.
1.Cross compile.Directly make then create executable file-serv in the root directory.
2.Put it on ramdisk or just nfs to test it.
3.Execute it then continuously create a picture in /tmp/1.jpg of ARM9.
4.Then you can see continuous pictures showed in lcd.

Notice:
Webcam capturing has two methods.One is mmap ,the other is read.
In this program,the default method is read,you can modify the value of grabmethod to change the capturing method. 
But in my all tests,the method of read is better:)
