With the rapid development of mobile internet, the projector becomes the terminal of mobile internet because of the network module embedded in smart projectors, which can provide a more convenient viewing experience. For traditional mini projector just as simple display equipment, the integration of Android operating system makes mini projector smarter, it is equivalent to a simple PC with projection function. This paper discusses the projection screen keystone distortion phenomenon of mini projector equipped with Android operating system under limiting projection environment because of different placement angle and how to eliminate the above-mentioned distortion, after elaborating the software and hardware architecture of smart mini projector, it focuses upon an analysis on how to achieve automatic correction of the projection screen using the digital acceleration sensor in hardware driver of the Android operating system.
