This research designed usable standard color chart which was planned by hue and tone color system. This research studied 5 types standard color chart by designed tone map and preceding research. "Basic Color Chart 14 Colors" was planned for kindergarteners. "Primary Color Chart 63 Colors" was planned for schoolboys. "Middle Grade Color Chart 114 Colors" was planned for junior high school students. "High Grade Color Chart 152 Colors" was planned for senior high school students. "Hue and Tone 205 Colors" was planned for university students and general publics. These 5 types standard color chart were produced the trial color coordinate card and attached the Munsell notation which could reappear the spare color paper when needed. These 5 types standard color chart would be offered the data base for efficient color coordinate education as school age.

Color chart area is automatically extracted in image that captured a crop such as fruits with the color chart, and an approximation formula is obtained for the change in feature value of the color indexes. Comparison is made with the color value of the crop area, and the growing degree is assessed according to the correlation. Using a compact PC equipped with the program, image of fruits is captured, and the output value obtained by the system is compared to the rating by expert. In the automatic recognition of the color chart out of doors, the complete color indexes is correctly acquired in 22 of 29 images. And indoors, they are correctly acquired in all of 34 images. In the color value judgment of the Japanese pear, indoors, 32 of 34 images is within 1.0 of the judgment error (compared the value read off by experts), the average error is about 0.5. These results indicate a practicable value.

This paper proposes color databases that can be used for various purposes for people with a color vision deficiency (CVD). The purpose of this paper is to group colors within the sRGB gamut into the CIE $L^*a^*b^*$ color space using the Brettel algorithm to simulate the representative colors of each group into colors visible to people with a CVD, and to establish a confusion line database by comparing colors that might cause confusion for people with different types of color vision deficiency. The validity of the established confusion lines were verified by using an Ishihara chart. The different colors that confuse those with a CVD in an Ishihara chart are located in the same confusion line database for both protanopia and deutanopia. Instead of the 3D RGB color space, we have grouped confusion colors to the CIE $L^*a^*b^*$ space coordinates in a more distinctive and intuitive manner, and can establish a database of colors that can be perceived by people with a CVD more accurately. Editor - Highlight - Do these changes reflect the intended meaning? If not, please rephrase as intended.

Since the beginning of time people had been using color to mark territory and decorate their surroundings. Color was taken for granted today as an intrinsic part of every waking moment. In modern age, color education was very important curriculum of art and design. In general, color expressed by hue, value and chroma but used the tone on the design spot, therefore the tone concept education was very important to color education. In this study I planned the usable "Systematic Color Coordinate System 180" for general color education on hue and tone color system and manufactured the color papers, color chart and color code based on the system. "Systematic Color Coordinate System 180" was attached the Munsell notation and common color names which could reappear the colors when needed.

본 논문에서는 컬러 보정차트를 이용한 디지털 영상의 컬러 보정 알고리즘을 제안한다. 제안된 알고리즘은 기준 컬러 값과 영상으로부터 취득된 컬러 값 사이의 컬러 변환 관계를 계산하기 위하여 별도의 컬러 보정 차트를 이용한다. 기존의 컬러 재현 알고리즘은 취득된 영상에 대한 컬러 스펙트럼 분석 및 디지털 영상의 형성 과정에 대한 모델링 등을 통한 방법을 이용하여 취득된 영상에 대한 컬러를 보정하는 방법을 주로 이용한다. 제안된 알고리즘은 차트로부터 제공되는 기준 영상과 취득된 영상의 컬러 사이의 변환 관계를 이용하여 컬러 보정 과정을 수행한다. 제안된 알고리즘은 두 단계로 수행된다. 컬러 보정의 첫 번째 단계에서는 컬러 차트의 영상을 취득한 다음, 내부의 기준 컬러 값과 차트 영상으로부터 취득된 컬러 값 사이의 변환 관계를 계산한다. 두 번째 단계에서는 계산된 변환 관계를 이용하여 차트 영상과 유사한 조건에서 촬영된 영상에 대한 컬러 보정을 수행한다. 제안된 알고리즘의 성능을 평가하기 위해서 다양한 조건 하에서 실험을 수행하였으며, 이를 일반적인 상용프로그램들의 컬러 보정 성능과 비교 및 평가하였다.

본 연구는 자주중산국수나무와 자주맥문동의 광도변화에 따른 생육 및 생리 특성과 엽색발현을 조사하여 적정 광도를 구명하고자 한 결과는 다음과 같다. 1.자주색 잎이 특징인 중산국수나무(Physocarpus opulifolius 'Diabolo')는 차광에 따른 생육 변화를 관찰한 결과 40% 차광구에서 생육이 좋았으나 양지조건일 때 생리활성이 2배 이상 좋은 것으로 나타났다. 엽색발현은 0% 차광구에서 85% 차광구로 갈수록 진한 자주색(RHS colour chart 202A, dark grayish red)에서 녹색(RHS colour chart 139A, dark yellowish green)으로 변화되어 본래의 품종 특성인 엽의 색이 사라져 관상가치면에서 저하된 것으로 사료되어진다. 2.자주맥문동(Ophiopogon planiscapus 'Nigrescens')은 노지상태인 무차광구에서 생육이 가장 양호하였고, 관상가치면에서 생육활성이 좋은 대조구에서 선명한 자주색이 잘 나타났으며 더욱 진해진 검붉은색(RHS colour chart 202A, dark grayish)으로 엽색이 발현되었다.

The purpose of this study was to arrange the korean women's hair styles of the beginning of 21st century and make hair style image making chart to use personal image making consulting data through analyze actress hair styles of broadcasting TV drama. To accomplish this purposes, picked up the two most popular dramas per each broadcasting stations, KBS1, KBS2, MBC, SBS, in february 2004. and analyzed and arranged hair styles of actress and at the last made the hair style image making chart.

삼각통을 포함하여 29개 토양통으로 분포되는 연초 경작지 67개 토양에 대하여 토양의 색 특성은 광학적 기기에 의해 측정되는 색차계 방법과 육안관찰에 의해 비색 평가되는 Munsell color chart 방법으로 비교되었고, 또한 토양의 화학성과의 상호관계가 검토되었다. 색차계로 측정한 토양의 색 특성 L, a 및 b 값은 Munsell color chart의 명도(V), 채도(C), 및 색상(H)과 밀접하게 관련되며 정량적 수치로 표현되었다. 토양 색 측정치의 표준편차는 2mm 체 통과시료보다 0.5mm 체 통과시료에서 적었다. 토양 색의 L, 및 b 값은 수분함량이 증가함에 따라 감소되는 경향이었으나 a 값은 수분함량의 변화에 따라 차이가 없이 비슷하였다. 그러나 풍건조건과 습윤조건(-10hPa)에서 측정된 토양의 L, a, b 값 각각의 상관계수는 r=0.90 이상으로 고도로 유의성 있는 정의 상관을 보였다. 따라서 토양 색의 측정은 일정한 수분 조건인 풍건토 0.5mm 체 통과시료에서 측정하는 것이 바람직할 것으로 생각되었다. 토양의 색 특성은 유기물함량, 양이온치환용량, 치환성 석회 및 고토 등과 유의성 있는 상관을 보였으며 특히 L 값은 유기물 함량과 가장 밀접한 관계를 보였다.

The tongue diagnosis is a diagnostic method in the oriental medicine that uses shape, substance, coating, and movement of the tongue to determine the condition of health and disease characteristics in human. Since this information, however, could be affected by subjective sense and visual information, it is difficult to obtain the objective and reproducible results. This research aims at building a reproducible tongue diagnosis system using color chart that is attached close to the face contact region. The picture of color chart is taken simultaneously with a tongue and applied to color revision. The system, in addition, is focused on providing a clear tongue image through securing a sufficient photographing distance with a surface coating mirror. The lightning part which can suppress the reflection by sputum in maximum is implemented for the objectification and quantification of the tongue diagnosis system. The face contact region is designed for consideration of a testee's convenience. To evaluate the reproducibility of the system, the CVs (coefficient of variance, %) of $L{\ast}$, $a{\ast}$ and $b{\ast}$ of red, green and blue regions in color chart are calculated, respectively. The results of all CVs shows that the tongue diagnosis system is re liable and those consequences contribute to the objectification and quantification of the tongue diagnosis system.
