Abstract
A display system with lens arrays at the front of a high-resolution LCD has been known as a method to realize an autostereoscopic three-dimensional (3D) display. In these displays, a light ray overlap between neighboring parallax images affects the image quality. In this study, the overlap effects were investigated for the one-dimensional (horizontal parallax only) integral imaging (1D-II) method. We fabricated samples of 1D-II displays with different levels of light ray overlaps and evaluated the 3D image by subjective assessment. It is found that the 1D-II display utilizing the proper parallax overlaps can eliminate banding artifact and have good 3D image quality within the wide range of a viewing area.
