디젠(대표 이길헌)은 지난해 국내에 처음으로 공급한 'Versa UV LEC-300'이 고객에게 새로운 수익원으로 자리매김하면서 고부가가치를 창출하고 있다고 밝혔다. 새로운 시장을 창출한 주인공은 서울 충무로에 위치한 정우프린팅(대표 권오성)이다. 지난해 UV 프린팅과 커팅이 동시에 가능한 'Versa UV LEC-300'을 국내에서 처음으로 도입했던 정우프린팅은 이 장비를 이용, 화이트잉크와 투명 광택잉크로 질감과 입체감 표현까지 표현하면서 고객들에게 고품질 고부가가치 출력시장에 만족을 주고 있어 1년 365일 가동을 쉬는 날이 없을 정도로 고객의 주문을 받고 있다.

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.

To perceive the direction and the distance of a sound, we always use a couple of information. Head Related Transfer Function (HRTF) contains the information that sound arrives from a sound source to the ears of the listener, like differences of level, phase and frequency spectrum. For a reproduction system using 2 channels, we apply HRTF to many algorithms which make 3d sound. But it causes a problem to localize a sound source around a certain places which is called the cone-of-confusion. In this paper, we proposed the new algorithm to reduce the confusion of sound image localization. The difference of frequency spectrum and psychoacoustics theory are used to boost the spectral cue among each directions. To confirm the performance of the algorithm, informal listening tests are carried out. As a result, we can make the improved 3d sound in 2 channel system based on a headphone. Also sound quality of improved 3d sound is much better than conventional methods.

Mobile industry has been progressed rapidly with new mobile technique develpment. The mobile is a communication device for the young generation and give great additional images through animations and characters. It is expected that the mobile industry would elevate greatly in means of the animation characters that is connected directly, closely, and amicably to the sense of humane beings. Of those animations, 3D animation is a high communication technique that rinks to directly the expression of person in way of a sense of space, three dimension, and reality. Surely the new 3D animation will be developed constantly and in various way. It is consideralbe that the manufacture of 3D mobile animation links closely to cartoon that forms concerns of people.

3 dimensional stereoscopic is attracting new attention as it simulates human eye and related hardware advances. However, 3 dimensional stereoscopic requires more time and effort than 2D movie because it uses 2 cameras or 2 lenses. This study analyzed the merits and demerits of the system producing rider movie using 3 dimensional stereoscopic shooting techniques and searched a way to produce better 3 dimensional stereoscopic rider movie which meets the producing intention by applying elements required to create effective 3 dimensional stereoscopic effect. According to the study result, a light-weight integrated system was effective to create 3 dimensional stereoscopic rider movie because of its genre characteristic. In the post-production of the work, location shooting considered of time re-mapping, color correction and graphic element addition was required.

디스플레이 장치와 영상 기술의 발전으로 3D 입체 영상에 대한 관심과 기술적 접근이 어느 때 보다 활발하다. 입체 영상의 경우 통상 복수의 평면 영상을 이용하여 합성하게 되는데 이 과정에서 각 영상의 객관적 화질을 서로 달리 함으로써 주관적 화질을 향상시킬 수 있다는 연구가 진행되어 왔다. 그러나 객관적 화질을 지나치게 달리 하거나 전반적으로 낮은 화질의 영상에서는 경계선이 제대로 재현되지 않아 입체감을 떨어뜨리는 문제가 발생한다. 또한 기존의 연구는 스테레오 영상에 한해서만 위의 가설을 검증하였으나 최근의 입체 영상에 관한 연구는 스테레오 영상뿐만 아니라 다시점 영상에서도 활발히 진행되고 있다. 본 논문에서는 스테레오 영상과 9시점 영상에서의 비대칭 영상 부호화가 주관적 화질에 미치는 영향을 검증하고 구체적으로 어느 정도의 객관적 화질 차이를 유지하는 것이 비대칭 부호화에서 가장 효율적인지를 밝힌다. 또한 기존의 비대칭 영상 부호화와 비교하여 주관적 화질을 개선할 수 있는 더욱 효율적인 알고리듬을 제안한다. 제안되는 알고리듬은 경계선의 강도를 기준으로 매크로블록의 양자화 파라미터를 달리 하여 영상의 경계선을 보호하는 방법으로써 기존의 비대칭 영상 부호화보다 더욱 향상된 주관적 화질을 얻을 수 있다.

In this paper, equalization zone of two crosstalk cancellation (CC) schemes, which are the one based on only head related transfer function (HRTF) and the other one based on interaural intensity/time difference (ITD/IID) as well as HRTF is studied. To do this, the condition numbers and ITD/IID levels of two schemes are shown.

We present a method to reproduce in-between views from captured stereo images to control depth feeling that a user can perceive on a 3D display. The stereo images captured from a pair of cameras have a fixed viewpoint and a screen parallax which depend on the physical position and the distance between the cameras. In this paper, we produce stereo images of an intermediate viewpoint between two original cameras by a view interpolation on the input stereo images. Furthermore, the camera separation of the reproduced stereo images can be controlled by a linear interpolation coefficient used by the view interpolation. By using the proposed method, stereo images can be reproduced where the depth feeling and a three dimensional effect is suitable for the individual's eye separation or the characteristic of an application.

All over the world, the interest in technology and industrial value has been increasing rapidly due to the continuing commercial successes of three dimensional films. However, after the commercial success of , without exception, lots of three dimensional films had been produced thoughtlessly. Hereby, these films incurred a censure owing to bad degree of completion related to insufficient storytelling and directing. For three dimensional films, characteristic of producing should be considered perfectly in the planning stage unlike previous films. This study concentrates upon proper directing for three dimensional films, and analyzes the method of it, roughly divided into three parts ; the lapse of time, directing the screen which can highlight space sense, and the point of sight. Henceforth, The demand of three dimensional contents will increase all around the world, at such time, we also should take note of the change, and then produce excellent contents which can lead to have a chance to gain the supper hand in the market of three dimensional contents.

There have been many studies on subject tests for 3D contents using 3D glasses, but there is a limited research for 3D contents using autostereoscopic display. In this study, we investigated to assess usability of electroencephalogram (EEG) as an objective evaluation for 3D contents with different quality using autosteroscopic display, especially for lenticular lens type. The image with optimal quality and the image with distorted quality were separately generated for autostereosopic display with lenticular lens type and displayed sequentially through lenticular lens for 26 subjects. EEG signals of 8 channels from 26 subjects exposed to those images were detected and correlation between EEG signal and the quality of 3D images were statistically evaluated to check differences between optimal and distorted 3D contents. What we found was that there was no statistical significance for a wave vibration, however b wave vibration shows statistically significant between optimal and distorted 3D contents. b wave vibration observed for the distorted 3D image was stronger than that for the optimal 3D image. This results suggest that subjects viewing the distorted 3D contents through lenticular lens experience more discomfort or fatigue than those for the optimum 3D contents, which resulting in the greater b wave activity for those watching the distorted 3D contents. In conclusion, these results confirm that electroencephalogram (EEG) analysis can be used as a tool for objective evaluation of 3D contents using autosteroscopic display with lenticular lens type.
