To ameliorate the polarized glassless type 3D display with a patterned retarder, we strongly recommend the i-PR (in cell black stripe Patterned Retarder) structure. In 3D mode, this particular structure can improve vertical viewing angle. When 2D switching mode is expressed, luminance and visibility will ameliorate at the same time

In this paper, the flood fill mean shift (FFMS) is introduced. This algorithm is developed for robust segmentation by improving the mean shift (MS) through the flood fill (FF) technique, instead of relying on spatial bandwidth. Due to this exchange, the FFMS involves only one parameter, the range bandwidth, which is not sensitive and is able to acquire global characteristics. If the image parts affected by the illumination changes are sufficiently small and their boundaries are not clear, the illumination effects do not influence the mode seeking procedure of the proposed FFMS. To prove the usefulness and the validity of our algorithm, we present several experiments and analysis of the results.

A three-dimensional simulation model calculating the optical intensity distribution for the entire screen of an autostereoscopic display at a given eye position was developed in this study. A parallax barrier array was used for the optical model and reverse ray tracing of light from the observer's eye to the subpixels through the slits of the barrier was performed based on reverse geometrical optics. By investigating the optical behavior of the displayed image for the nine-view design condition for various viewing distances, we found the inhomogeneous crosstalk from the unwanted views and predicted segmented images which were comprised of multiple images from different views on the entire display screen. From the results, our simulation model shows good potentiality for predicting the displayed image on the entire display screen of autostereoscopic displays for various positions of the observer's eye with sufficient calculation speed.

Stereoscopic/autostereoscopic systems have been developed to express 3D images, but have not been successfully use in practise. In order to apply 3D display to promising applications such as advertisements and games, we developed a 42" 2D/3D switchable display. It has characteristics that do not require special glasses for 3D images, uses multi-view technology for improving 3D viewing characteristics, and has a 2D/3D switching function to express dynamic 3D contents as well as conventional 2D contents.
