The invention discloses a real-time image special-effect display realization method. The method comprises the following steps: determining physical parameters of a display device, and obtaining movement track of the display device in real time; determining the length, width and rotation angle of an output video image according to the physical parameters and the movement track of the display device; and keeping synchronization of the output video image and the display device according to the length, width and rotation angle of the output video image and the movement track of the display device. In the movement process of the display device, stability of the displayed video image of the display device can be maintained without carrying out pre-processing on a video source, thereby achieving a purpose of image special-effect display.
