Abstract
A method of displaying an image having a first aspect ratio with a display device having a second aspect ratio includes receiving image data for the image, buffering the image data and creating a frame of the image at the first aspect ratio, defining a first sub-frame and a second sub-frame for the frame of the image at the second aspect ratio, including spatially offsetting the second sub-frame from the first sub-frame in one direction, and alternating between displaying the first sub-frame in a first position and the second sub-frame in a second position spatially offset from the first position with the display device, including optically scaling a displayed image of the first sub-frame and a displayed image of the second sub-frame in the one direction.
