Point light source integral imaging with improved resolution and viewing angle by the use of electrically movable pinhole array

A resolution and viewing-angle enhanced integral imaging system using electrically movable pinhole array is proposed. A pinhole array on liquid crystal is adopted as dynamic pinhole array in integral imaging. The location of the pinhole array is controlled electrically. The pinhole array is expected to be moved fast enough to make an after-image effect, and the corresponding elemental images are displayed synchronously without reducing the 3D viewing aspect of the reconstructed image. With the proposed technique, the resolution and the viewing angle can be improved remarkably, and the upper resolution limit imposed by the Nyquist sampling theorem is overcome. The explanation of the proposed system is provided and the experimental results are also presented.

View image generation in perspective and orthographic projection geometry based on integral imaging.

A novel technique generating arbitrary view images in perspective and orthographic geometry based on integral imaging is proposed. After capturing three-dimensional object using a lens array, disparity estimation is performed for the pixels at the selected position of each elemental image. According to the estimated disparity, appropriate parts of elemental images are mapped to synthesize new view images in perspective or orthographic geometry. As a result, the proposed method is capable of generating new view images at arbitrary positions with high resolution and wide field of view.

Stereoscopic conversion of two-dimensional movie encoded in MPEG-2

We present an algorithm for stereoscopic conversion of two-dimensional movie encoded in MPEG-2. The stereoscopic algorithm consists of segmentation process and depth determination process. In the segmentation process, we segment the image based on the dc information and the motion vector information encoded by MPEG-2. After the segmentation, depth of each segment is determined by examining the motion vector and the overlapped region of the segment.

A novel view image generation algorithm using lens array is proposed. Arbitrary view image in perspective projection geometry is generated through the central pixel disparity estimation and elemental image mapping with wide field of view and high resolution. View image in orthographic projection geometry is also synthesized with high resolution from the elemental images using directional pixel disparity estimation and elemental image mapping.

Improved viewing resolution of three-dimensional integral imaging using pinhole array on LC panel

In this paper, we propose a resolution-enhanced integral imaging with pinhole arrays on liquid crystal (LC) panel. Since light through a pinhole corresponds to a pixel in 3D image, we electrically move the pinhole arrays on LC panel fast enough to make after-image effect and display corresponding elemental image synchronously without reducing the 3D viewing aspect of the reconstructed image. The explanation of the proposed system will be provided and the experimental results will also be presented.
