Recently, 3D integral imaging system, which is well known as an auto-stereoscopic 3D display method, has been gaining great attention amongst researchers. The integral imaging is a promising 3D display technology since it is able to deliver continuous viewing points, full parallax, and full color view to the observers in space. In this paper, we propose a novel interactive 3D integral imaging system using a single camera. The user interface is implemented by adding a camera in the conventional integral imaging system. To show the possibility of the proposed system, we implement the optical setup and present the preliminary results. To our best knowledge, this is the first time to study an interactive 3D integral imaging.

We present an autostereoscopic 3D display system using volume hologram. In this proposed system, the interference pattern of angular multiplexed plane reference and object beams are recorded into a volume hologram, which plays a role of guiding object beams of multi-view images into the desired perspective directions. For reconstruction, object beams containing the desired multi-view image information, which satisfy Bragg matching condition, are illuminated in the time-division multiplexed manner onto the crystal. Then multiple stereoscopic images are projected to the display plane for autostereoscopic 3D viewing. It is possible to make a high resolution multiview 3D display system independent upon the viewpoint.

A 3D projection display using stacked screens to display the near and far images, respectively, is developed. The front screen is made of a scattering polarizer film, and the far image on the rear screen is clearly visible through it. The image is perceived as three-dimensional, and no eyestrain is suffered.

A method to make the near and far images for a double layer 3D display system to create continuous depth illusion has been studied. The luminance ratio between the near and far images should be allocated based on the tone reproduction characteristics of the display systems.

Synthetic aperture integral imaging is one of promising 3D imaging techniques to capture the high-resolution elemental images using multiple cameras. In this paper, we propose a method of displaying 3D images in space using the synthetic aperture integral imaging technique. Since the elemental images captured from SAII cannot be directly used to display 3D images in an integral imaging display system, we first extract the depth map from elemental images and then transform them to novel elemental images for 3D image display. The newly generated elemental images are displayed on a display panel to generate 3D images in space. To show the usefulness of the proposed method, we carry out the preliminary experiments using a 3D toy object and present the experimental results.

In this paper, we introduce an eye-tracking 3D display system using variable parallax barrier and DDC communication. A barrier of variable parallax barrier composed of 4 sub-barriers and a commercially available web camera is utilized to implement the eye-tracking system. The coordinates of a viewer is extracted from the web camera transfer to 3D display via DDD/CI communication. The variable barrier attached to the LCD moves electrically according to the right eye position for 3D images. This system is compared experimentally with the commercial parallax barrier methods.

In this paper, we propose real-time 3D image converting architecture by a unit of pixel for 2D/3D compatible PC and LCD of cellular phone with parallax burier, and implement a system for overall display operation after designing a circuit based on FPGA. After digitizing anolog image signal from PC, we recompose it to 3D image signal according to input image type. Since the architecture which rearranges 2D image to 3D depends on parallax burier, we use interleaving method which mixes pixels by a unit of R, G, and B cell. The propose architecture is designed into a circuit based on FPGA with high-speed memory access technique and use 4 SDRAMs for high performance data storing and processing. The implemented system consists of A/D converting system, FPGA system to formatting 2D signal to 3D, and LCD panel with parallax barrier, for 3D display.
