Paper Abstract

In this paper, we describe a method to combine two integral photography (IP) displays to represent a larger amount of depth while maintaining image quality. We adopt integral videography (IV), which can emit 4D light fields into real space to present full-parallax 3D videos. The two IVs are located at different depths on the same optical axis by using a beam splitter. We present some steps to enhance the quality of our 3D display. First, we remove positional displacements based on an adjustment between the LCD and the lens array of IV. The positional displacements include parallel, rotational, and depth displacement. Next, we strictly adjust the two IVs' positions to right positions. Adjusting geometrical positions is based on optical rotations and shifts. Finally, we run the hidden surface removal to hide surfaces of 3D objects on the background display to prevent viewers from seeing the distracting surface. In conclusion, our optically multilayered light field display is effective for enhancing the depth of field.
