In this paper, viewing zone-forming geometry of multiview imaging systems and lens image forming principle is applied to prove that the depth sensing mechanism of integral photography (IP) is both parallaxes. The proof is based on the fact that making the cell size of each elemental image the same as a microlens pitch does not change the geometry, because there are no changes in the field-of-view of each microlens. The total number of different view images perceived in the viewing zone of IP, and the compositions of the images and condition of increasing the number are also identified.
