1. A computer implemented method for improving the angular field of view for a person watching an image on a screen, the method comprising: (a) capturing an image of a scene in front of the screen; (b) converting the image into a digital data form; (c) detecting the position of an image of a human face in the captured image; (d) calculating at least one deviation between the detected position of the human face image in the captured image and an imaginary line that passes through the center of the image on the screen and extends substantially perpendicular to the screen; and (e) rotating the screen in a direction to reduce the calculated deviation.
