Abstract
Viewing zones of contact-type multiview (MV) three-dimensional
(3D) imaging and Integral Photography (IP) are defined based on geometrical
optics, and then the compositions of images projected to viewers' eyes at
viewing regions of the viewing zones are analyzed. This analysis reveals that
each image is composed of a pixel from each participating pixel cell to form
the central and side viewing zones. In the regions between the viewing zones,
one or two pixel cells do not contribute any pixel. However, when the total
number of pixel cells in forming the viewing zones is large, one or two missing
pixel cells may not deteriorate the image quality. In this sense, the side
viewing zones are not working independently but they work together with the
central viewing zone to build a bigger combined viewing zone. The analysis
also reveals that the combined viewing zone of IP is not different from the
viewing regions between viewing zone forming optics and the viewing zone cross
section of the MV viewing zone, in its characteristics.
