Correction of distortion of frameless multi-view displayed modules for large-screen autostereoscopic display

Abstract

We have proposed the tiling of frameless multi-view modules, which consists of a multi-view display and a magnifying imaging system, to construct large-screen autostereoscopic displays. However, the distortion in the image generation on the display screen and that in the viewpoint generation in the viewing zone were observed. In this study, the distortions are expressed by higher-order polynomial functions that are estimated from measured data. Then, displayed images are anti-distorted to correct the distortions. The effects of the corrections were experimentally verified.
