  • Purpose. The purpose of this study was to investigate the effect of lens color of sunglasses on stereoacuity by experiment. Methods. We conducted a stereotaxic test using a RANDOM DOT with a polarizing lens at an examination distance of 40 cm in 100 men and women aged 20 to 60 years without any specific ocular disease. Then, seven kinds of PVC color film such as yellow, black, brown, red, purple, blue and green were put on the polarizing lens and the stereoscopic examination was carried out again. Results. When the lens color of the sunglasses is yellow, black, and brown, it affects less stereoscopic effect. However, red, purple, blue, and green have much influence on stereoscopic effect. Especially, the red and purple colors affected the stereoscopic vision. In blue and green, the effect of stereoscopic vision was different according to the people. Conclusions. Depending on the lens color of the sunglasses, stereoscopic vision is affected, which can cause problems in binocular vision. Therefore, when choosing sunglass lens color, many buyers need to pay attention.

  • Stereoscopic 3D animation contents are in the rise as a key part of contents market. Major animation studios are planning to produce 3D animations in a stereoscopic process. This study aims at understanding the visual textuality of 3D animation contents at its early stage. To understand 3D animation, , are analyzed. Stereoscopic 3D animations are exploring the new visual aesthetics using the specific storytelling, sequence ordering, camera working, shot size and camera angles etc. Based on these visual textualities, stereoscopic 3D animations are constructing telepresence, multi-senses of individual spectators. Stereoscopic 3D animations have formed their own aesthetics and cultural meanings in the digital age.

  • Success of brought a large revolution in the world of cinema and the media market. They have predicted new industrial possibility for 3D Stereoscopic image and trends started to support for producing in the field of various media platform. We can see our domestic technology creates higher added value in the sphere of hard-wear for the market of worldwide home TV electronics. But in reality we are short of effective and organized pipeline of producing and we should analyse cases more for Stereoscopic 3D animations. Therefore in this paper, we present case study on animation made into Stereoscopic 3D animation to build up suitable Stereoscopic 3D TV animations pipeline. We differentiate from any other Stereoscopic content by applying artistic elements and technological elements, especially human factor and 3D Sweetening to elevate the level of 3D Stereoscopic effect for main audience, children. We propose how to strengthen the competitiveness of Korean animation for world animation market.

  • Horizontally-moving method (HMM) stereoscopic camera has a liner relationship between ver-gence and focus control. We introduced the automatic control method for a stereoscopic camera system that uses the relationship between vergence and focus of an HMM stereoscopic camera. the Automatic control method uses disparity compensation of the acquired image pair from the stereoscopic camera. For faster extraction of disparity information, the proposed binocular dispar-ity estimation method by the one-dimensional cepstral filter algorithm would be investigated. The suggested system in this study substantially reduced the controlling time and error-ratio so as to make it possible to achieve natural and clear images.

  • Simultaneous CH and OH planar laser induced fluorescence(PLIF) and stereoscopic particle image velocimetry (PIV) measurements have been developed to investigate the local flame structure of turbulent premixed flames. The developed simultaneous two radical concentrations and three component velocity measurements on a two-dimensional plane was applied for relatively high Reynolds number turbulent premixed flames in a swirl stabilized combustor. All measurements were conducted for methane-air premixed flames in the corrugated flamelets regime. Strong three-dimensional fluctuation implies that misunderstanding of the flame/turbulent interactions would be caused by the analysis of two-component velocity distribution in a cross section. Furthermore, comparisons of CH-OH PLIF and three-component velocity field show that the burned gases not always have high-speed velocity in relatively high Reynolds number turbulent premixed flame. The Reynolds number dependence of the flame front was clearly captured by the simultaneous CH-OH PLIF and stereoscopic PIV measurements.

  • This letter introduces a stereoscopic video broadcasting system that provides 3D visual service and has full backward compatibility with legacy digital television (DTV) service in the same channel capacity. The proposed stereoscopic video broadcasting system in this letter is composed of both a hybrid codec and a multiplexer with a newly defined stereoscopic-related signaling method. In conclusion, the proposed method can be effectively applied for 3D broadcasting services without major changes in legacy broadcasting platforms.

  • Micro-PIV(particle image velocimetry) has been widely used to measure the velocity of micro flow. Although this micro-PIV method can give accurate 2D instantaneous velocity information of mea-surement plane, it cannot resolve the out of plane component of velocity vectors. Lots of the micro fluidic devices generate three-dimensional flow and 3D measurement of velocity is useful to understand the physics of micro flow phenomena. In this study, we constructed stereoscopic micro-PIV(SMPIV) system and applied this method to the impinging micro jet flow. The results show that this method can produce accu-rate 3D reconstruction of micro jet flow.

  • The study analyzes how to create stereoscopic image in 3-dimension animation 'Yggdrasil', produced in Autodesk Maya(3D animation software), using Anaglyph method that is the oldest in 3-dimension stereoscopic video production. The anaglyph method help to produce stereoscopic images easily and to give effective 3D effect encoding each eye's image using filters of different colors. In addition, space direction applied visual perception theory expresses necessary distance, depth and speed effectively in 'Yggdrasil'

  • This paper presents the stereoscopic conversion of flame images. The stereoscopic conversion is a technology that generates left and right images from a monoscopic image. Even though many conversion methods have been introduced and commercialized so far, the processing of flame images is relatively few. Such conventional methods are effectively used either real-time or off-line. However, the application of such schemes to special-effect images such as flame is hard to be applied. The proposed method is designed to convert a flame image into a stereoscopic image. Depth map of flame regions are produced based on the analysis of color models of flames. Experimental results tested on diverse flame image sets validates the effectiveness of the proposed method.
