Abstract: A method for angularly varying backlight illumination of a backlit display device. The method comprises determining at least one subject position and angularly varying a backlight illumination of a displayed image. The backlight illumination is angularly varied based upon and directed towards a determined position of the at least one subject. The angularly varied backlight illumination of the displayed image reduces the backlight illumination of the displayed image that is visible outside of the determined position of the at least one subject.
