| 20110019156 | PROJECTION SYSTEM AND METHOD THEREOF - A projection system and a method thereof are provided. The projection method includes the following steps. First, a processing module of an electronic device acquires a process ID of an application program via an operating system of the electronic device. Next, the processing module extracts display data corresponding to a window of the application program from a frame buffer of the electronic device stepwise with a predetermined frequency. Next, the processing module produces a plurality of pictures based on the extracted display data with the predetermined frequency. Next, the processing module transmits the pictures to a projector according to a predetermined transmission protocol. Finally, the projector projects the pictures sequentially. | 01-27-2011 |
