Video display correction to provide on-axis view at an off-axis angle

Abstract

Embodiments describe methods, apparatus and systems to provide video display correction to provide an on-axis view at an off-axis angle so that the display surface displays a rectangular video image. For instance, a device may receive a stream of video data to be displayed on a display surface of a display, the video data having a first rectangular aspect ratio to be viewed from an on-axis location with respect to the display surface. The device may also receive a user selection of an off-axis viewing angle with respect to the display surface. The device may then correct the first rectangular aspect ratio to a second, non-rectangular aspect ratio based on the off-axis viewing angle, so that from the off-axis angle, the display surface appears to display a rectangular video image. Other embodiments are also described and claimed.

What is claimed is: 
     
         1 . A method comprising:
 receiving a stream of video data to be displayed on a display surface of a display, the video data having a first rectangular aspect ratio to be viewed from an on-axis location with respect to the display surface;   receiving a user selection of an off-axis viewing angle with respect to the display surface; and   changing the first rectangular aspect ratio to a second, non-rectangular aspect ratio based on the off-axis viewing angle.
