  • This paper describes work by the authors aimed at reducing the mismatch between accommodation and convergence when viewing stereoscopic 3D images. Two methodologies, one a simple system with a mono-focal lens and the other a dynamic system using a moving LCD, were introduced as experimental 3D displays with optical correction. The results of usage evaluations suggest improvements in health and amenity can be achieved with stereoscopic representation with accommodation.

  • Define a designated eye position (DEP) for the 3D displays is a critical issue. It shows the system performance without content issue. We use luminance meter to capture these optical characteristic and discuss between one point measurement, two points measurement and three points measurement situation.

  • The super multi-view (SMV) display and the high-density directional (HDD) display were proposed as a natural 3D display that is free from the visual fatigue caused by the accommodation-vergence conflict and provides smooth motion parallax. The multi-projection system, the flat-panel system, and the time-multiplexing system are used to construct the HDD displays. The recent progress of the HDD 3D display is reviewed.

  • In this paper, an accurate ray-tracing based visual analysis method of lenticular 3D liquid liquid crystal display (LCDs) and some analysis results are presented. In the developed method, the geometric optics analysis is performed on the single 3D unit pixel of 3D lenticular LCD. It is shown that the display characteristics of 3D lenticular LCD panels of arbitrary size can be evaluated through the 3D unit pixel analysis. The analysis results of a few representative structures of 3D lenticular LCDs are compared.

  • We have developed a 2D-3D convertible 7" autostereoscopic mini-monitor with high 3D quality, in which the parallax barrier LCD is attached on the TFTLCD. The excellent optical performance was achieved by design of the ghost free barrier and precise assembly between the barrier layer and the TFT-LCD panel. Our design principle and fabrication technology suppressed 3D cross-talk and improved viewing angle. In this paper, the design and fabrication process of the 3D mini-monitor are described. The evaluation for the 3D performance is also discussed.

  • Almost all 3D displays have a brightness reduction in the 3D mode comparing to the 2D mode. When the brightness is reduced, one of the color attributes, the colorfulness, is decreased. In this case, the viewer feels that the image quality is deteriorated. In this paper, we proposed a method to compensate for the degradation of colorfulness due to brightness reduction in 3D mode for high quality 3D image viewing using the CIECAM02 model and the color correction matrix. As a result of applying the proposed method, we can confirm that the colorfulness is improved in 3D mode.

  • 본 논문에서는 기존 무안경식 3D 디스플레이의 제한된 시야각으로 인한 3D 시청에서의 불편함을 해소하기 위해 새로운 패렐랙스 배리어 방식을 제안한다. 제안된 방식은 기존 패렐랙스 배리어의 TN-LCD 구조에서 LC를 공유하는 이중 계층의 ITO 쌍을 추가하였으며, 시선 추적 장치에 의해 시청자의 위치를 감지하여 자동으로 3D 시야각을 시청자의 위치에 맞도록 변화 시킬 수 있는 이중 계층의 패렐랙스 구조를 갖는다. 제안한 이중 계층 패렐랙스 배리어 방식을 시제품으로 구현하고 실험한 결과, 제안한 방식의 유효성을 확인할 수 있었다.

  • Common stereoscopic three-dimensional (3D) display has a convergence and accommodation conflict that violates the natural human cognitive process of viewing. This weakness exposes the challenge in supporting fun factors while eliminating safety problems in the 3D viewing experience. Thus, human factors have become a major research topic. In this letter, we propose a 3D stereoscopic visualization platform that can expand the sense of a 3D space by fusing organically mixed stereoscopic displays to provide a continuous feeling of 3D depth. In addition, we present pilot test results to show the possibility of the technical implementation of the proposed platform and note ongoing research issues to be addressed.

  • Stereoscopic (3D) content must be viewable in a variety of visual environments, from 3D theaters to 3D mobile displays. However, the depth sensations provided by 3D media are affected by the viewing conditions, such as screen size, viewing distance, and other factors. This user experience (UX) aspect makes it difficult to create multi-purpose 3D content. This paper describes two study cases in which the authors have focused on the UX and the multi-purposing of 3D content. The first case is an evaluation of 3D image quality on a mobile display. The second case is a trial development of a scalable 3D conversion process.
