Abstract
Typical depth priority integral imaging (DPII) method with large depth is
composed of a lens array and a display panel where the unwanted color artifact of the
reconstructed 3D image may be produced due to the subpixel structure of the display
panel. In this paper, to reduce color artifact in the DPII system, we propose a new DPII
system with a lens array based on three sublens configurations. In the proposed system,
each voxel color of 3D object is reconstructed by the integration of the subpixel images
from three sublenses to display red, green, and blue colors. In addition, we introduce a
new subpixel rearrangement algorithm to generate the modified elemental images for the
proposed system. To show the feasibility of the proposed method, we carry out the
preliminary experiments for color images and present the experimental results. The
results reveal that the proposed system can reduce color artifact of 3D images compared
with the conventional integral imaging system.
