Data Conversion from Multi-view Cameras to Layered Light Field Display

Abstract (in Japanese) (See Japanese page) 
(in English) Layered light field display is an auto-multiscopic 3-Dimensonal display which consists of a backlight and several light attenuating layers.
The transmittances of the layers' pixels can be controlled individually, and are determined inversely from a set of multi-view images which is expected to be observed.
We have evaluated the output quality by using computer graphics and confirmed that aliasing artifacts are occasionally observed from the directions without input images.
To prevent aliasing artifacts, it is necessary to limit the disparities between neighboring input images into $pm 1$ pixel according to plenoptic sampling theory, which requires significantly small viewpoint intervals.
However, it is not always possible to capture such dense multi-view images that would satisfy the aliasing-free condition.
To tackle this problem, we propose to use image based rendering techniques for synthesizing sufficiently dense virtual multi-view images from actually photographed images.
