  • 본 논문에서는 단일 영상에 포함된 광원의 분광분포를 추정하는 광원추정 알고리즘을 제안한다. 제안된 광원 추정 방법은 두 단계로 이루어져 있다. 첫째, 변형된 회색계 가정(modified gray world assumption)을 이용하여 부분적으로 광원의 영향을 배제한 후 밝으면서도 무채색에 가까운 최대 무채색 영역을 찾아 그 영역의 표면 분광 반사율을 구한다. 이때 최대 무채색 영역의 표면 분광 반사율은 1269개의 Munsell 색 표본에 대하여 주성분 분석 방법을 이용하여 추정하였다. 둘째, 주어진 Munsell 색 표본과 대표 광원의 조합으로 반사광의 모집단을 만들었다. 다음 최대 무채색 영역의 각 화소와 반사광 모집단과의 색차를 비교하여 최대 무채색 영역과 색차가 가장 적은 반사광 표본을 선택하고 이를 최대 무채색 영역에 대한 반사광의 분광분포로 정의한다. 최종적으로 최저 무채색 영역의 반사광 분광분포를 해당하는 표면 분광반사율로 나누어줌으로써 영상에 포함된 광원의 분광분포를 추정한다. 제안한 알고리듬의 성능을 평가하기 위하여 유색 광원에 조명된 영상에 대한 광원 추정 실험을 하였으며 기존의 방법과 추정된 광원의 분광 분포 비교 및 색차 비교를 통해 그 타당성을 검증하였다.

  • The purpose of this research was to conduct a comparison analysis of color in the characteristics and image of Korea/China/Japan airline uniforms. Research subjects for this research included 19 Korean, Chinese and Japanese airlines servicing the Incheon International Airport in South Korea. The analysis methods are based on the Munsell Color Order System and PCCS (Practical Color Coordinate System) tone classification in order to examine the color characteristics. For the color image analysis, the present research performed a positioning on Shigenobu Kobayashi's color images scale with adjectives in order to compare the resulting differences. As a result of the analysis, this research discovered the following; First, achromatic colors were found to be used most frequently in flight attendant uniforms of Korea/China/Japan. In Korean flight attendant uniforms, YR/Y, GY and B/PB/P; in Chinese, R/PB, RP, YR/Y/GY and BG/P; in Japanese, RP, R/P/PB and Y/BG were found in order. As for the main uniform colors, Korean flight attendant uniforms were found to be in the colors YR, and R/GY/B/P; Chinese flight attendant uniforms, R, PB, and P/B; and Japanese flight attendant uniforms, R, BG, B, RP and N. Second, Korean flight attendant uniforms used W and It most frequently; China flight attendant uniforms, W; and Japanese flight attendant uniforms, W and v. Regarding the main colors, Korean flight atteddant uniforms used lt/g and v/p; Chinese flight attendant uniforms, v, dp and s/d/dkg; and Japanese flight attendant uniforms, v/dkg and Bk. Third, after positioning each country's uniform color combination bars on the Kobayashi image scale, Korean flight attendant uniforms showed classic images along with casual/pretty/elegant/chic images; Chinese flight attendant uniforms displayed, casual images as well as, dynamic/gorgeous/chic/cool casual/dandy images; and finally, Japanese flight attendant uniforms converyed dandy images along with casual/gorgeous images. This research findings indicate that Korea/China/Japan airlines' flight attendant uniforms seek for differentiated image establishment by reflecting their own CIs and unique national cultures in the uniform color marketing.

  • The objective of this research is to examine the commonness and differences of Korean, Chinese and Japanese costume colors of modern and present ages. The result of this study showed that modern China and Japan had quick influx speed of Western culture. Dissimilarly, modern Korea kept conception of colors from Chosun periods that show the high frequency of 'Five Elements Colors' and neutral colors in Red, Yellow and Purple Blue. Today, the costumes of China, Korea and Japan use similar tones of color but each country approached in different selections of achromatic colors; Korean prefers color in Yellow Red, Purple, and Chinese in Green Yellow, Green and Japanese in Purple Blue. Light greyish and pale toned Yellow Red and grayish tone have increased in modern Chinese and Japanese costumes. Also both countries have corresponding assumptions in using color of Red in strong tone. The analysis of color and tone distribution showed that, Japanese costume colors in modern and present times have correlative number of use as in Western culture. Traditionally, Japan has least notion of using 'Five Elements Colors' which only gives minor changes by convergence of Western color culture. In other side, China had developed in color rather than tone compares to Korea and Japan by using many of the Red color of strong, vivid and deep tones which made red distinguishing color of China. Japan continues to use of low chroma colors and became a characteristic in modern and present day, also they use an abundance of color in Yellow Red, purple Blue. Korea has a higher frequency showing in light, bright tones of color distinctively compares to China and Japan.

  • 시각과 관련된 감성 연구 중에서 색에 대한 연구나 움직임에 대한 연구는 많이 이루어져 왔으나 정적인 형태 자체에서 감성을 불러일으킬 수 있는가에 대한 연구는 많이 이루어지지 않았다. 따라서 본 연구에서는 기본적인 3가지 형태를 중심으로 색상과 결합하여 영역 설정(AOI)에 의한 시각적 주의를 아이트래킹을 활용하여 분석하고 그 결과를 Heat Map과 Gaze Plot을 통해 시각적으로 표현하였다. 또한, 두 집단과 평균 차이에 대한 통계적 유의성을 검증하기 위해 대응표본 t검정을 실시하였다. 실험결과, 유채색의 형태가 무채색의 형태보다 시각적 주의가 크며, 난색의 형태가 한색의 형태보다 더 높은 평균을 보여 시각적 주의가 크다는 것을 알 수 있었다. 본 연구는 주관적으로 해석되기 쉬운 디자인적 요소를 객관적인 해석이 용이한 정량적 방법을 제시하는데 의의가 있다. 향후 본 연구결과를 토대로 더 많은 추가 연구가 수행되어 다양한 색상과 형태로부터 시각적 주의의 차이를 확인할 수 있는 정량적 해석 방법이 제시된다면 기초 디자인에 대한 가이드라인을 제공하는데 활용될 수 있을 것이다.

  • This study aims to be the useful resources for selecting play therapy facility in the future by analysis of used colors in the play therapy facility as the subsequent studies of the thesis of KIID in 2010, titled 'Study on the planning factors of case study for children's play therapy center'. As research method of this study, the overall understanding about play therapy facility was improved through theoretical considerations, and it was about the Moon-Spencer's theory of color harmony which will be used for the framework of case study. In Section 3, the field trips at 6 facilities were conducted as the case research and the data research through website was conducted for case study. Moon-Spencer's theory of color harmony used the Munsell's color Order System, so after measuring CMYK value of the picture for the case research through photo shop, the color, brightness and saturation were measured through Munsell Conversion program. The following three kinds of features were drawn by research of the harmony and disharmony of used colors for the cases after substituting the theory of color harmony through the measured color. brightness, and saturation. First. series Y and YR were used mainly for warm image as the concept of play therapy room. Second, the various colors were used for comfortable image like home. But the various patterns were used by mixing for the therapy room F, so it gives confusing impression. Third, series YR and achromatic color as the color of wood were used unavoidably for using materials of manufactured goods.

  • 등광도인 두 색으로 이루어진 배경(적색/녹색, 청색/녹색, 혹은 청색/황색 배경) 위의 중앙에 회색 원이 놓일 때 이 회색 원에 대한 잔상은 본래의 두 배경 색에 대한 가산 혼합 색인 것으로 나타났다. 잔상에 나타난 이러한 흔한 색은 두 배경 색의 광도가 다를 때에도 나타났고, 회색 인의 크기가 증가하였을 때에도 나타났다. 나타난 잔상의 채도는 순응 배경 자극의 평균 광도 값이 증가할수록, 그리고 회색 원의 크기가 감소할수록 증가하는 것으로 나타났다. 하지만 검사 자극의 중앙에 유채색 혹은 무채색의 경계선이 놓일 때 순응 자극의 두 배경 색에 대한 가산 혼합 색은 더 이상 나타나지 않았다. 검사자극에 놓인 경계선은 검사 영역의 양 쪽에서 유도된 객들이 반대편의 영역으로 퍼져나가는 것을 방해하고, 결과적으로 유도된 색이 두 색으로 분리된 상태로 유지하도록 하여 서로가 혼합되지 않도록 돕는 작용을 하는 것으로 추정된다. 검사 자극에 경계선이 놓이지 않는 경우, 잔상에서 유도된 색은 유도된 두 색 사이에 주관적 경계선을 형성하기에는 너무 약한 색 정보를 가지기 때문에 결과적으로 두 색이 반대편의 영역으로 퍼져 색채 혼합이 일어나는 것으로 추정된다.

  • The purpose of this study is to obtain specific data about the characteristics of color preference on Women's street fashion within China and Korea. Photos of Women's street fashion from the twenties and thirties were taken in person in four cities in China(Beijing, Dalian, Qingdao and Nanjing) and Seoul from July 2nd to August 10th, 2015. Three hundred photos in each city were selected, making a total of 1,500 photos. In the analysis of the colors of the clothing in these five cities, the uses of the multi color was most frequent in Dalian, while those of Black was most prevalent in Beijing, Qingdao, Nanjing and Seoul. The Black proved to be commonly preferred through all the items, regardless of terms of the nationality, areas and seasonal changes. The high incidence of Purple Blue color in Beijing, Dalian and Qingdao might be attributed to their preference of the blue jeans. The Multi color was highly shown in all the cities which might be due to their preference of compound colors rather than the mono ones. The high preference for the chromatic colors such as Red, Yellow Red and Yellow might be ascribed to the Chinese traditional color preferences. The differences lies in the color tones, such as the dark and light grayish tone emphasized in Seoul and Nanjing, and vivid and strong tones in Beijing, Dalian and Qingdao. Seoul shows a liking for the achromatic colors, preferring dark and grayish tones, compared with four cities in China, only Nanjing has a similar trend to Seoul. This study analyzes geographical preferences in China that possibly contribute to the launching of Korean fashion brands in view of the design and marketing as a useful basic resources.

  • This study examines and analyzes the current status, characteristics and properties of Super-Graphic as a visual element with Super Graphic designed on the wall of apartment housing, typifies them and explains the preference and evaluative structure by each type. The results of this study are as follows: According to color environment of Super-Graphic, N-tone colors are 21.4% and YR-tone colors are 14.5%. In the whole distribution, cold color tone is 41.4% and warm color tone is 37.2%. In the brightness, 72.9% of the entire Super Graphic use high brightness and in the saturation, 51.2% show low saturation, achromatic colors are 21.4% and high saturation is 16.5%. As a result of conducting SD test to analyze the preference of Super-Graphic, 'wonderful' is most negative variable, followed by 'heterogeneous', 'splendid', 'romantic' variety'. Positive variables are 'monotone', 'stable' and 'calm'. As a result of factor analysis to reveal the evaluative structure of Super Graphic image based on the above results, five factors including brightness, saturation, stability, harmony and ordered are extracted and it is considered that these are important variables to be reflected in designing Super Graphic in future.
