Recent researches based on integral imaging display method

摘要

Integral imaging is one of the most feasible directional displays that give different perspectives according to viewing directions. It has inborn characteristics such as viewing angle, resolution, and depth range because of lens array or pinhole array. In this paper, recent integral imaging techniques for improving these features in display are reviewed. New approaches such as integral floating display and two-dimensional three-dimensional (2D/3D) convertible integral imaging method are described as well.
