PROJECTION SYSTEM AND METHOD THEREOF
First Claim
1. A projection method, adapted to project a window of an application program executed by an electronic device, the projection method comprising the following steps:
- obtaining a process ID of the application program through an operating system of the electronic device;
extracting display data corresponding to the window from a frame buffer of the electronic device stepwise with a predetermined frequency according to the process ID;
producing a plurality of pictures with the predetermined frequency according to the extracted display data of the window;
transmitting the pictures to a projector according to a predetermined transmission protocol; and
sequentially projecting the pictures by the projector.

Abstract
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.

11. A projection system, comprising:
-
a projector having a first connection port; and an electronic device, coupled to the projector, the electronic device comprising; a second connection port coupled to the first connection port of the projector; a processing module capable of executing an operating system, a first application program, and a second application program, wherein the second application program is capable of obtaining a process ID of the first application program through the operating system; a display capable of displaying an image; and a frame buffer coupled to the processing module, and capable of saving display data of the image, wherein when the processing module executes the second application program, the processing module extracts display data corresponding to a window of the first application program from the frame buffer stepwise with a predetermined frequency according to the process ID, and the processing module produces a plurality of pictures with the predetermined frequency according to the extracted display data of the window and transmits the pictures to the projector through the first connection port and the second connection port according to a predetermined transmission protocol, such that the projector projects the pictures sequentially. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
