Abstract:
1. A method of displaying a video, comprising: projecting the video onto a viewing screen having at least one screen cover located in front of the viewing screen; determining, after the video is projected onto the viewing screen, if a height dimension and a width dimension of the video that was projected onto the viewing screen matches a height dimension and a width dimension of the viewing screen; altering, after the determination that either the height dimension or the width dimension of the projected video does not match the height dimension and the width dimension of the view screen, one of the height dimension and the width dimension of the viewing screen while keeping the other of the height dimension and the width dimension constant by moving the at least one screen cover in front of the viewing screen with respect to the viewing screen when an aspect ratio of the video based on the height dimension and the width dimension of the video does not match the aspect ratio of the viewing screen, wherein the at least one screen cover is continuously displaced from a corresponding edge of the viewing screen when the at least one screen cover moves toward a center portion of the viewing screen and the at least one screen cover is continuously displaced from the corresponding edge of the viewing screen when the at least one screen cover moves away from the center portion of the viewing screen; determining, after the altering, whether a width of the video matches the width dimension of the viewing screen; zooming the width of the video in response to the width of the video not matching the width dimension of the viewing screen; shifting the video to an alignment position through aligning a height of the video with the height dimension of the viewing screen, wherein the video is projected onto the alignment position in the viewing screen; and storing the alignment position of the video in a non-volatile memory.
