Inkjet printing technology can reduce the LCD color filter manufacturing cost more than 50 %. Uniform color filter patterning can be achieved only with proper ink and barrier materials. We developed new ink and black matrix materials for inkjet color filter. The ink materials have low volatility while they have very high solid content. The black matrix materials have very precisely controlled surface energy so that the inks can fill the pixels evenly and completely. We controlled the ink drop volume and ink material to minimize the thickness difference between the black matrix and the color pixel. Micron-order jetting position accuracy was achieved. We successfully printed 14.1" color filters using our ink and black matrix materials.

디지털 카메라(Digital Camera)와 같은 휴대형 영상 입력 장치(Portable Image Input Device)는 스캐너 (Scanner)와 달리 3 차원의 피사체(Object)를 디지털 영상으로 생성할 수 있고 다양한 조명 환경(Illuminant)에서 사용할 수 있다는 이유로 많은 응용 분야에서 활발하게 사용되고 있다. 그러나, 정확한 색 재현(Color Reproduction)을 위한 기존의 디지털 카메라 특성화 방법(Digital Camera Characterization Method)은 생성된 영상의 조명 정보를 고려하지 않은 상태에서 색 변환 행렬을 생성하므로 다양한 조명 환경 변화에 대해 적응적으로 대처하지 못하는 단점이 있다. 본 논문에서는 디지털 카메라가 생성하는 영상의 rgb 색도를 이용하여 색도 평면에 색도 다각형(Chromaticity Polygon)을 구성하고 각 색도 다각형들간의 포함 관계에 따라 조명 정보를 평가함으로써 조명색(Illuminant Color)의 변화에 따른 인간 시각 시스템(Human Visual System)의 색 불변성(Color Constancy)을 재현할 수 있는 디지털 카메라 특성화 방법을 제안한다.

The purpose of this research is to investigate the tendency of color preference for the elderly in housing. For this, a questionnaire survey was carried out with color chips and 9 photos of the living rooms which were chosen among apartment model houses in Pusan. Preference of color usage was measured by SD scale developed by advertising adjectives for the model houses. The result of this study are as follows: 1) The preferred color image was characterized as soft, warm and simple. The main factors of color image were identified and named as 'dignity factor' and 'personality factor'. 2) The elderly preferred G generally, but R for dominant color of the living room. They distinguished their attitudes about the color by the purpose of color usage. 3) For colors of architectural components of the living room, preferred colors were narrowed Y, YR and R for wall, art wall and floor. Beige was the most popular color in the living room for the elderly. This research can contribute to the basic data of color planning for the elderly housing.

Beijing as one of the prosperous cities has been attracting more and more to the people in China and overseas because of the coming Olympic Games. And the housing enterprises have become extremely popular as follows. The request of housing designation has also been increased and a color factor should be the key point of housing designation. This study is a research of perceptual color designation in public residential housing in Beijing. In particular, this study will deal with the color designation development trend of public residential housing in Beijing after an analysis of color designation of high-class residential housing from 2000 to 2007 in Beijing. Color around people is not only understood more rationally and personally in 21 century but also it is pursued to get a brand-newly incentive from tradition. While color could give housing many wonderful looks. Chromatics people have had a deeper acknowledge of color and color function so color has played a key role of housing designation. Color effect on people in physical and physiology aspect is getting more important. The color issue are one of the most effective and efficient factor in the in public residential housing, therefore this study deal with this issue 'How to effectively use the color in public residential housing space.

스트룹 효과(Stroop, 1935)는 매우 신뢰롭게 관찰되는 현상으로 이를 응용한 다양한 연구들이 존재한다. 전통적인 스트룹 실험에서는 색과 색 이름을 실험자극으로 사용하였으나 이후 연구들은 어떤 색(예: green)과 그 색을 전형적으로 보여주는 대상의 이름 (예: grass)을 사용한 경우에도 일치 혹은 불일치 조건에 따라 유사한 효과가 발생한다는 것을 보고하였다(Klein, 1964). 그런데 의미표상(semantic representation)의 검증을 위해 스트룹 효과를 활용한 기존 연구들은 대부분 구체적인 대상들과 색의 연합을 검증했기 때문에 구체명사(concrete noun)와 그에 상응하는 색 이름을 연구에 활용하였다(예: Dalrymple-Alford, 1968, 1972; Klein, 1964). 그런데 최근 Sherman과 Clore(2009)는 구체적 대상이 없는 단어의 도덕적인 의미(예: honesty, crime)에 따라 흰색 혹은 검은색으로 제시되었을 때에도 색에 대한 반응이 빨라지거나 느려진다는 것을 보고하였다. 이에 근거하여 본 연구에서는 스트룹 과제를 사용하여 형용사의 온열감각 차원의 의미 (예: 따스한, 냉정한)와 색 온도 (따뜻한 색, 차가운 색)의 연합을 스트룹 과제를 통해 검증하였다. 그 결과 형용사의 온열차원의 의미와 색 온도가 불일치할 때 보다 일치할 때 참가자들은 색에 대해 더 빠르게 반응한다는 것을 확인할 수 있었으며, 형용사의 의미와 색 온도 간의 상호작용을 관찰할 수 있었다. 본 연구의 결과는 스트룹 관련 연구들에서 주로 사용해온 구체명사가 아닌 추상적인 형용사에서도 스트룹 효과가 발생한다는 것을 보여주었다는 점에서 기존 연구들과 차이점을 가진다. 또한 무채색을 사용한 Sherman과 Clore(2009)의 연구와 달리 색상을 사용한 경우에도 단어의 의미에 따라 스트룹 효과를 획득할 수 있다는 새로운 결과를 보여준다.

We present a surface color measurement including quantities of surface color, methods, and uncertainty evaluation. Based on a relation between spectral reflectance and surface color, we study how an uncertainty of spectral reflectance propagates to surface color. In analyzing the uncertainty propagation, we divide the uncertainty into uncorrelated components, fully correlated components, and correlated components with spectrally varying correlations. As an experimental example, we perform spectro-reflectometric measurements for ceramic color plates. With measured spectral reflectance and its uncertainty evaluation, we determine surface color and analyze uncertainties of the ceramic color plates.

Because buildings which apply color that is various to concrete recently are introduced, value as design element of building is rising gradually in townscape. Even if expense is increased according as importance of concrete that have variety of design because do such social background and connection is emphasized, development of color concrete is pressing. Therefore, in this research, examined concrete physical & chemical characteristics by use of acid agent as part of research to embody diverse surface color of cement material. Here, embodiment of various color by unique color that stained hydrate has as that Color Concrete forms stained oxide that react with hydrate within concrete spreading stained agent that contain acid and metallic-ion in matrix that have cement ingredient on the surface is available.

A high dynamic range (HDR) video service is an upcoming issue in the broadcasting industry. For compatibility with legacy devices receiving a non-constant luminance (NCL) signal, new tools supporting an HDR video service are required. The current pre-processing chain of HDR video can produce color noise owing to the chroma component down-sampling process for video encoding. Although a luma adjustment method has been proposed to solve this problem, some disadvantages still remain. In this paper, we present an adaptive color noise reduction method for an NCL signal of an HDR video service. The proposed method adjusts the luma component of an NCL signal adaptively according to the information of the luma component from a constant luminance signal and the level of color saturation. Experiment results show that the color noise problem is resolved by applying our proposed method. In addition, the speed of the pre-processing is increased more than two-fold compared to a previous method.

Color is distinguished due to the light in which natural light is reflected by object and made with combination of RGB(red, green, blue; three colors). This study proposes color analysis system with optical method to be used conveniently. Color information of sample is determined with the optical sensor. By using the CIE diagram in particular, it detects purity value and wavelength. The method to distinguish color is very economical, simple, and convenient. The result can be used to confirm accurate information of color for various applications.
