Although design, color, and material are important elements in stage costumes, stage lightning also plays significant role in the presentation of stage costumes. Costumes color, material and perception can be significantly influenced by visual effects. Stage illumination can be arranged or managed so that colors are closely related to or enhanced or change the effects of costume colors on the runway or display at specific times. The results of this thesis are as follow; 1) Fabric tone, name, brightness, and chroma of colors were changed by the colors of stage lighting. 2) An achromatic color was changed to a chromatic color after being combined with colors of stage lighting. 3) Stage illuminations can make fabric, colors look similar to stage colors. 4) Plain satin silk fabric which reflects light shows high brightness and chroma after being influenced by stage lighting its shining effects and color changes were clear and apparent. 5) Velvet pile fabric which absorbs light shows low brightness and chroma after being influenced by stage lightning its shining effects and changes of colors were not clear and apparent. In conclusion, natural lights did not significantly influence fabric colors and perception, while artificial lights had wide range of effects on fabric colors and perception.

We propose an architecture for a lighting engine for mobile 3D graphics. The proposed architecture has a variable pipeline depending on lighting effects and the number of lighting sources so that unnecessary operations and power consumption are minimized. We design a lighting engine basedon the proposed architecture using Verilog-HDL and synthesized it using a 0.25um CMOS standard cell library at 100MHz. The synthesis results show that it occupies 180,000 and 260,000 gates for 24bit and 32bit formats, respectively.

The paper proposes a method for generating a sequence of images with smooth transition of illumination from two input images with different lighting conditions. Our relighting approach is image-based, such as the light field rendering. We store the luminances (pixel RGB values) into "lighting functions" consisting of a couple of parameters related to normal vectors. Images with different light positions are rendered by interpolating the luminances retrieved from the lighting functions. The proposed method is a promising technique for many applications requiring a scene with variety of lighting effects, such as movies, TV games, and so on.

Indoor of 21th century information-oriented society is feeling necessity of emotional design that can satisfy emotional of human. Desire of modern becomes various and emotional lighting design is risen on important element in indoor plan on human oriented modern society who become complicated. Emotional space is trend that is atomized as go today and is expanded as the target and area also go. That is, is included as target of emotional space to light and sound, taste, smack and is appealing by senses of human. Wish to do color that is optical element among element of senses differently and present design. Design concept of this research is emotional lighting design that can receive. It is lighting that equip emotional beauty and ability from modern indoor improving space. I wish to quote emotional lighting design about effect gotten to indoor by sight of designer.

This study suggests experimental designs for interior products utilizing LEDs that are ideal for expressing diversity of light. It also attempts to develop various products by incorporating economic efficiency and diverse colors of LEDs into interior elements. LED door handles offer a range of 6-color LED lighting strips as a safety lighting system, while multi-function furniture (CUBE-scape) consists of LEDs with double-sided emitted lighting on completely transparent track structures. Both products are designed to make interior elements more user-friendly as they make most use of unique effects of LED such as light vibration and changes. Also the combination of plastic material-Technogel$^{\circledR}$, polypropylene, polycarbonate- maximize the LED lighting effect and diversify the designed item selection.

조명은 공간을 비추는 기본적인 기능 외에 진보된 기술과 디자인으로 다양한 연출 효과와 함께 공간에 효율성을 좌우한다. 공간의 효율성에 적합한 조명설계는 공간의 입지적 여건과 램프 특성에 따라 설계되어질 때 가능해진다. 특히, 특수공간의 조명설계는 공간적 특수성을 감안하여 사전 분석과 검토가 요구된다. 따라서 본 연구에서는 방폐장 터널의 공간적 특수성을 감안한 조명환경을 위하여 사전의 조명설계와 시뮬레이션을 통한 적합성 검토를 하고자 한다. 이에 무전극형광램프를 제안하며 방폐장 터널의 입지현황에 따라 구간별 조명설계 기준과 구성을 제시하고 이를 통한 조명설계를 바탕으로 시뮬레이션 분석을 하여 적합성 검토한다.

This study was carried out to obtain fundamental information on the growth response of interior landscape plants under fluorescent light, sunlight and optical fiber lighting indoors. Saintpaulia ‘Delaware’, ‘Kalanchoe blossfeldiana, Anthurium scherzerianum and Ardisia crenata were examined using light intensity of 5001ux and 1,0001ux of fluorescent light, sunlight and optical fiber lighting in an interior environment. Results of experiments are as follows; 1) Plant growth status showed the best results under optical fiber lighting compared with fluorescent light or sunlight. 2) Plant growth status was better under 1,0001ux light intensity than 5001ux light intensity and in cases of the same light intensity, the highest growth increase was under optical fiber lighting. while it was showed relatively different according to the different plant species between a fluorescent light and sunlight. 3) The deep pinkish red color of Saintpaulia ‘Delaware’flower was obtained first under an optical fiber lighting and a fluorescent light, a sun light in that order. 4) Regarding interred activity, photosynthetic rate and transpiration rate, intercellular CO, water absorption rate showed a similar tendency generally in spite of a little difference. Namely, transpiration rate and intercellular CO, $CO_2$ a absorption rate increased according to increase of photosynthetic rate. 5) Photosynthetic rate of test plants except Anthurium scherzerianum increased according to increase of light intensity and increased highest under optical fiber lighting in the same light intensity condition. Increases differed under fluorescent light and sun light. That of Saineaulia ‘Delaware’and Anthurium scherzerianum increased in the order of optical fiber, fluorescent light and sun light, but that of Kalanchoe blossfeldiana and Ardisia pusilla increased in the order of optical fiber lighting, sun light and fluorescent light. Summing up these results, In visual value or internal health status of all experimental plants we obtained the highest result under an optical fiber lighting. Finally, we need to introduce an optical fiber lighting in interior landscape space as main light source.

색채와 조명의 결합은 영상 공간 예술효과의 가장 중요한 표현 수단으로, 색채 조명은 아름다운 느낌을 창조하여 관중들의 심리에 영향을 미치는데 사용되기에 이는 아주 강한 표현력과 감화력을 갖고 있으므로 이미 현재의 영상 장면에서 관용하는 수단으로 되었다. 공간조명 원리와 무대조명의 색채 응용원리에 대한 연구, 그리고 왕가위 감독의 영화와 Baz Luhrmann의 영화를 비교 분석을 통하여 영상 공간에서 색채 조명의 응용을 연구하고 희극, 비극적 분위기를 부각시킨다. 색채 조명을 어떻게 응용해야 영상 공간의 분위기를 부각시킬 수 있는지에 대한 원칙을 도출하는데 그 목적이 있다.

It is highly important issue to use an energy efficiently for sustainable prosperity of mankind. From this point of view, using LED lighting can be a good alternative because it has a lot of advantages such as high efficiency, long life time and eco-friendly manufacturing process. That is the reason why using LED lighting has been encouraged worldwide. However, in situations that LED lighting is replacing traditional lighting quickly, the problem of the flicker of LED lighting has emerged as an important issue. Therefore, in foreign countries like US or Japan in order to ensure the reliability of LED lighting, study for flickering effects of the human body and test methods are have been actively conducted. But related research in domestic situation is an insufficient condition. In this study, a flicker characteristic was measured conventional lamps such as incandescent lamps or fluorescent lamp and 81 items of LED lightings which are distributed in domestic markets.
