Efficient of viewing sub-regions in the stereo hologram display

The super-multiview condition in the stereo hologram display is analyzed. The viewing zone of the display consists of viewing regions. Each of these regions can project images of having 1 pixel disparity difference with those of its immediate neighbors and its width can be smaller than the viewers´ pupil size when the sizes of pixels in each pixel cell becomes smaller than 10 μm. Hence each of these regions can work as a basic image cell which provides a pixel disparity with its immediate neighboring cells and has the width smaller than viewers´ pupil size.
