Paper Abstract

We analyzed resolution characteristics of a lenticular-sheet 3D display system. The measured samples are onedimensional integral imaging (1D-II) display systems of 9-18 parallaxes with slanted/vertical lenticular sheet. The measured contrast ratio curves of various sinusoidal patterns as functions of depth are in good agreement with the theoretical resolution limit for both vertical and slanted lenticular-sheet types. The 1D-II display systems with parallel beam configuration show spatial distribution of resolution in the horizontal direction corresponding to parallax crosstalk. If the parallax crosstalk is not designed properly, this distribution is observed as moiré pattern and degrades 3D image quality. When the gap between the lenticular sheet and the elemental image plane changes in the depth direction, the apparent resolution curve shifts in the same direction; if the gap is large, objects displayed at the near side have higher resolution, and if the gap is small, objects displayed at the far side have higher resolution. This phenomenon is also explained by an effect of the parallax crosstalk caused by defocusing.
