A standard default color space, sRGB, provides compatibility for the transmission of color within the Internet color operating systems and device drivers. However, a display monitor we use generally have non-standard primaries and gamma characteristic different from those specified by sRGB. In this paper, correction methods of chromatic error for a non-standard display monitor are proposed. Experimental results show that the proposed method using the correction matrix reduced chromatic errors at in compared with the non-corrected image's on a non-standard display.

The process of selecting a small number of representative colors from an image of higher color resolution is called color image quantization. In a color quantization process, it is vet important to determine what colors should be preserve and the others not. In our study, by the idea of an image can be divided into interesting area and uninteresting area, we propose a color quantization method that preserves more colors in the interesting area of an image. We evaluated correctness of extracting interesting area and compared the quality of our method with the others.

We studied visual clarity according to the difference of color temperature and color rendering by using black and white printed paper and four sheets of colored paper under different kinds of lamps and same kind lamps. The results show visual clarity is proportioned to average color rendering index approximately except incandescent lamps and to color temperature under incandescent lamps, fluorescent lamps, high pressure sodium lamps, metal halide lamps and electrode less discharge lamps.

본 논문에서는 고차 신경망 (High-order Neural Network) 을 이용한 LCD 모니터의 색 보정 방법에 관해 제안하였다. 스캐너를 통해 입력받는 영상과 LCD 모니터상에 보여지는 영상의 색을 고차 신경회로망을 통해 보정하였다. 측색기를 이용하여 색표의 값을 측정하고 이를 신경회로망의 출력으로, LCD 모니터에 나타나는 값을 입력으로 하여 학습하였다 입력은 측정값들의 상관항으로 구성되는 집합을 구성하여 고차 신경회로망의 입력으로 사용하였다. 최적의 실험결과를 얻기 위해 은닉층의 수와 노드 수를 변경하며 실험하였다. 실험을 통해 고차 선경회로망을 이용한 방법으로 원색에 가깝게 보정 됨을 확인하였다.

Ocular inspection in oriental medicine, which identifies sickness by patient's skin color, is usually applied by doctor's subjective judgment. In order to reduce the subjectiveness of diagnosis, we propose a method of objective and quantitative analysis for ocular inspection. The most issued features for ocular inspection are how to identify the color of patients' face in various situations, and how to link the relation between color and sickness. For resolving these two issues, the color system of CIE Lab is adopted for analyzing and classifying the color characteristics. The classification of color features is verified by experiments on groups of patients and non-patients. The results of experiments showed that the proposed method can provide an objective means for ocular inspection using patient's skin color.

This experiment was conducted to develop a healthy tea by fumigation, low temperature drying, drying and instant immersion using flowers of Robinia pseudoacacia L. that bloom in May in all regions of Korea. The drying was drying after fumigation treatment, low temperature drying, drying and instant immersion. The color of the flowers, beverage color, the sugar content, and the taste of the beverage were measured after changing the weight of the flowers. The change in the weight of flower tea was 11% ~ 12.5% of the body weight. The change in the color of the flowers appeared to be the lightest brown in the treatment of drying, and the other treatment area became turbidity white. The color of the beverage was yellowish from the tea treated with drying and became pale yellow when fumigation, low temperature drying and instant immersion. Sugar content was highest at 2.9brix from the drying and 2.6-2.7brix at the other three treatments. The taste was the best in the drying treatment, and the instant taste dipped in the tastes.

The emotions evoked by single color or two-color combinations are investigated using bipolar affect adjectives. The color emotions using 10 bipolar affect adjectives are estimated for 5 single color patches and 10 two-color patch combinations. Twenty observers participated in the experiment and the same experiments are repeated using English and Korean words. The data analysis shows that there is little difference between English and Korean experiment. In many cases, color emotion for two.color combination can be predicted by averaging the color emotions of each patch. However, there are other cases that the emotion by one color dominates the emotion for the color pair.

현대 사회의 건강관리 분야에서 기존의 서양의학이 아닌 한의학을 이용하는 것에 관심이 증대되고 있는 실정이다. 이에 한의학의 진단 이론인 사진법 중 가장 뛰어난 망진을 활용한 진단기기의 개발이 의료비 절감 및 국민건강 증진에 기여할 것으로 사료된다. 본 논문에서는 망진 중 찰색을 위한 진단기술 개발을 위한 연구를 진행 하였으며 실험을 위해 일정한 환경을 설정하고 이와 같은 환경에서 임상자료를 수집하여 색상 분석을 실행하고 디지털 색 체계 분석을 위한 연구를 진행하였다. 특히 실험을 통해 찰색에 필요한 오색(흰색, 검정색, 빨간색, 파란색, 노란색)의 추출에 적합한 디지털 색 체계로서 LAB 색체계의 효율성을 밝히고 이를 통한 실제 피부색 비교 및 분석을 진행하였다. 최종적으로 실험의 의한 피부색 분석으로 찰색에 유용한 기준 설정을 행하고자 한다.

Stroop effect(Stroop, 1935) is a reliable paradigm which has been used in various psychological research. Although classic Stroop experiment used color and color name for experimental stimuli, subsequent research reported that a color(e.g. green) and an object(e.g. grass) which displays a typical color show similar effects depending on color-object congruency(Klein, 1964). Because past research that used Stroop effect to investigate semantic representation tested association between concrete object and color, they predominantly used concrete nouns and their corresponding color names as stimuli(e.g. Dalrymple-Alford, 1968, 1972; Klein, 1964). Recently, Sherman and Clore(2009) reported that response time to white or black words is affected by moral value of words (e.g., honesty, crime) even when the words do not have specific referents. Based on this result, we tested association between thermesthesia-related adjectives(e.g., 따스한, 냉정한) and color(warm color, cold color) using Stroop task. The results showed that subjects were faster in their response to color when adjective-color was congruent than when incongruent, and there was an interaction between color and meaning of adjectives. The Stroop effect in this research is unique because, contrary to previous research that used concrete nouns, the effect was obtained even with abstract adjectives which do not have specific referents. In addition, unlike Sherman and Clore(2009) that used achromatic color, our results show that Stroop effect obtains between abstract adjectives and chromatic color.

본 연구는 화장지용 펼프원료로 저급지인 색지(color ledger)고지를 사용함으로써 생산원 가를 절감하기 위한 목적으로 실시되었다. 일반적으로 색지 고지는 azo dyes, stilbene dyes, c copper phthalocyanine dyes와 같은 직접염료(direct dye)로 착색돼있는 것으로 보고되고있 다[) 한편, 펄프표백에 사용되는 약품은 hydrogen peroxide(HzOz), ozone(03), sodium h hypochloriten업oeD와 같은 산화표백제들과 F AS (formamidine sulfinic acid), sodium h hydrosulfite(NazSz04)와 같은 환원표백제들이 사용되는 것으로 널리 알려져 있다. 보통 화 장지용 펄프는 백색도가 78%이상이 되어야만 제품생산에 사용할 수 있는 것으로 인식되고 있다. 따라서 색지 고지를 이 목표로 달성하기 위한 탈색방법을 확립코자 다음과 같은 2가 지 실험을 실시하였다. 먼저, 색의 3원색인 빨강, 노랑, 파랑색의 색지 고지를 동일한 양으로 혼합하여 PY, HY, YH, YH, HY와 같은 5가지 방법의 실험을 실시하였다. 이중 YH 방법 이 가장 우수한 것으로 나타났다. 이 결과를 근거로 하여 여러 가지 색으로 구성된 색지 고 지가 50% 함유한 백상지 고지를 사용하여 Table과 같은 약품 및 조건으로 표백을 겸한 탈 묵실험을 실시하였다. 이 실험에서 백색도 81.8%, L* 93.3, a* -0.5, b* 4.1의 결과를 얻었다. 색지 고지의 탈색은 Y 단계에서 pH와 온도에 큰 영향을 받는 것으로 본 실험을 통하여 알 수가 있었다.
