Abstract
A video processor is responsive to an output of a pair of cameras that are used for determining a viewer viewing direction of a display screen. As long as the viewer's viewing angular direction is directed toward a center region of a display screen, the pan function is disabled. When the viewer's viewing angle crosses a first threshold angular direction away from the screen center, dynamically tracking pan function is enabled so as to shift the displayed picture. When the viewer's viewing angle crosses an even larger, second threshold angular direction, the picture will shift in the same direction but at a faster rate. When the viewer's viewing angular direction decreases in a manner to cross a threshold angular direction that is smaller than the first threshold angular direction further picture shift is suspended. Thereby, a hysteresis feature is incorporated. When the viewer's viewing angular direction continues changing in the same direction that causes the suspension in the picture shift in a manner to cross a third threshold angular direction, that is adaptable to the accumulated picture shift, the picture shifts in the opposite direction.
