Abstract
A display device has a display panel for displaying a composite image to allow a viewer to see a 3D image. The composite image has a plurality of right and left image strips alternately arranged. The display device also has camera to monitor a viewing position of a viewer. The camera has a camera lens and a sensor with a plurality of right sensor zones and left sensor zones to capture the viewer's right eye and left eye images. When the viewer is at a viewing position that the 3D image viewed by the viewer appears pseudostereoscopic, the viewer's right eye image is in one of the left sensor zones and left eye image is in one of the right sensor zones. A processor changes the order of the right and left image strips so that the viewer can see a orthostereoscopic image at that viewing position.
