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.
We propose a new capturing system to realize capture of elemental images for an autostereoscopic display based on a
one-dimensional integral imaging (1D-II) method. In order to realize a capturing system for the 1D-II display, capturing
elemental images with fine pith and containing much horizontal parallax information with wide angle are important. The
optical system composed of a cylindrical lens, a focusing lens and an imaging device can capture elemental images
having these two features with scanning over an object. Furthermore, the system size can be small by adapting a
compact scanning optical system of a copy machine. We captured 200 elemental images at a fine scan pitch of 0.5 mm.
There were 92 horizontal pixels on each elemental image. The number of horizontal pixels correspond the number of
parallaxes. The angle range of the captured parallaxes was 42 degrees. Using the autostereoscopic display based on the
1D-II method, the synthesized image can be observed to be a correct three-dimensional (3-D) image.
