Abstract
A method and apparatus for providing a three-dimensional display to a viewer is disclosed. If a color difference between pixels of a right eye image area and corresponding pixels of a left eye image area is greater than or equal to a predefined difference threshold, a parallax barrier is controlled to block either the right or the left eye image area from the viewer. Otherwise, if the color difference is less than the predefined threshold, the parallax barrier is controlled to display both the right and left eye image areas to the viewer. Corresponding devices to implement the method are also disclosed. The method may be performed by an autostereoscopic display controller, or a pair of active shutter glasses, for example.
