ABSTRACT:
The present invention provides a three-dimensional display system by using Integral Photography (TIP) technology. The present invention comprises an elemental lens switch located between a lens array and an image display for selectively opening and closing each elemental lens; an image processor for generating elemental images and synchronizing them with control signals of the elemental lens switch; an image display for displaying the elemental images; and a lens array comprising elemental lenses, for forming the three-dimensional image by refracting and integrating the elemental images displayed on the display. Hence, it is possible to display three-dimensional images with a wider viewing angle than that of the conventional IP method, because each elemental lens is synchronized with the corresponding elemental image and is switched properly.
