Paper Abstract

Detecting depth information from a pickup image of integral imaging is of great importance since it is the first step for providing integral imaging systems with some flexibility against various system specifications and display environment. One problem of the depth extraction in the integral imaging is that the gap between the lens array and the elemental image plane cannot be determined exactly since the desired value depends on the object depth itself. Moreover, an object to be picked up is preferred to be located close to the lens array to ensure sufficient resolution in the elemental image and the detected depth profile, which makes the gap deviate too far from the focal length of the lens array, and thus disturbs exact depth extraction. In this paper, we propose a depth extraction method using a uniaxial crystal in addition to the lens array. The proposed system can detect the depth without prior knowledge of gap between the lens array and the elemental image plane. We explain the principle and verify it by simulation and experimental results.
