Reproduced colors which are half-tone dot printed at the rate of 10, 20, 30, 100% half-tone dot area by each process ink-cyan, magenta and yellow ant at the rate of 10, 20, 30, 100% by the mean color mixing of black, cyan, magenta and yellow, are colorimetric analyzed by make use of the 1931 CIE XYZ system of color specification and matching the Munsell color system. With increased half-tone areas, 1. Yellow has ideal reflectance curve, but magneta has nonideal reflectance curve. 2. Yellow and cyan have almost standard dominant wavelengths but magenta has complementary wavelengths. 3. Yellow has higher excitation purities in primary colors, but low excitation purities in secondary and third colors. 4. Value function is decreased and generally the range of value function in chromaticity diafgram is extented. 5. The properties of black and CMY printed materials have not equality, therefore black process ink is necessery in half-tone printing process.

Color is one of the most important attributes determining the purchase of food products by consumers. Therefore, the purpose of this study was to identify consumer color preferences for songpyun, a traditional Korean rice cake, by a consumer acceptance test and using coated Pantone color chips. Color evaluation tools for the study were developed accordingly. From the results, the songpyun sample designated as product E was given the highest color acceptability score, and was 'slightly liked' (p<0.05). The color of product E was 'very pale red-purple'. All the evaluated pink-color songpyun products were based on this red-purple hue, however, they had differences in tone. The consumer panel favored a pale tone over a bright tone. The color concept for traditional songpyun within the pink color category was identified as 'very pale red-purple', using coated Pantone color chips. This result for the conceptual color preference was consistent with that of the consumer color acceptance test. Thus, color chips could be an effective tool when applied for color standardization in traditional foods production. From the overall results, it seems consumers are perceiving color trends and are willing to adapt to such changes in food applications.

This study examines the rotor characteristics of Guybang culture (women's living in Joseon) relics which the life images and mental world of women in Joseon if expressed to prepare rotor data to be utilized in modern design and information for color identity establishment of Korean women culture. The result of this study is as following: 1. From 176 pieces of relic photos, total of 1380 color chips were extracted. For color analysis, 1368 units (99.1%) of color data excluding achromatic 12 units (0.9%) among 1380 units of colors were used. With the standard of 10 color wheel of Munsell Color System, the result of studying distributions according to frequency, red was the highest by 25.9%, yellow was 21.4% in women's goods in Joseon period which the ratio of red and yellow was 473%. Other than that, GY 14.6%, YR 11.3% and RP 11.1% followed next which is studied that the warm colors that conveys enjoyable and glamorous feelings composed 84.3%; 2. As a result of tone analysis, high value low chroma ltg color showed highest distribution of 20% and d was 12.2%, b was 11.7% and sf was 8.8%. Generally, it showed high frequency in high value cocors such as ltg, sf and b of 40.5%t and in low chroma (ltg) and medium chroma (d, sf) of 41% and colors in bright and calm image was used the most. 3. As a result of analyzing relationship between hue & tone, the ltg tone of Y close to white in traditional color sensibility showed the highest frequency of 9.6% and ltg tone of GY(6.4%), b tone of RP(6.1%), and v(5.4%), b(5.4%), dp(5.3%) of R followed next. 4. As a result of analyzing the characteristics of coloring, it showed that in case of coloring contrasting hues, it is adjusted similar tones and in case of coloring less contrasting hue, the difference in tone is adjusted to be rather large to make harmonized coloring. Moreover, in case of coloring similar hues, the ratio of using same tone and similar tone was large which the coloring of calm image and dynamic image is all used.

Fiber industry is export leading industry that guide national economy development after the 1960s in Korea. But lately, including China and Southeast Asia pursuit, domestic fiber industry is taking serious situation. Various kind methods can be proposed for high value added in fiber industry, the research about color is essential. The importance of color is increasing in modern textile and fashion industry. Color is important factor of textile and fashion industry because color affects strong influence in human's sensitivity. Color expresses by hue, value and chroma but fashion industry is using mainly hue and tone color system. Daegu Gyeongbuk area is domestic maximum syntheic fiber producing district. This study planned the polyester standard color collections for general color management of the polyester industry in Daegu Gyeongbuk. As basic research for this I investigated the color appearance distribution of polyester fabrics in Daegu Gyeongbuk that were produced for the recently 10 years and Japanese polyester color collections "SCOTDIC 2450". Reflect these study finding, in this research planned the usable standard color collections "Hue and Tone Polyester Standard Color 288".

본 논문에서는 모바일 폰 카메라의 적용을 위한 자동백색보정(Auto White Balance, AWB) 기능 중에서 단색영상에 대한 탈색 현상과 색상의 왜곡을 막기 위한 단색영상 검출 알고리즘을 제안하였다. 기존의 자동백색보정 기능은 복합영상의 경우에는 정상적으로 자동백색보정이 수행되었지만, 입력영상이 단색이거나 단색이 상당량 포함되어 있는 영상이 입력되는 경우에는 해당 색상이 탈색되거나, 입력영상의 색상 성분에 의해서 자동백색보정의 결과가 왜곡된 색상으로 나타나는 문제점이 발생하였다. 본 논문에서는 자동백색보정 수행 시 상기 단색영상에 대한문제 점을 해결하기 위하여 입력 영상의 색상정보에 대한 히스토그램 데이터를 이용한 단색영상 검출 알고리즘을 개발 하였다. 본 논문에서 제안하는 알고리즘을 자동백색보정 기능에 추가적으로 적용된다면 더욱 향상된 기능의 자동 백색보정이 수행될 수 있을 것이라 기대한다.

In this paper, a new technique for color reproduction based on color variation characteristics of digital camera under a dim light condition is proposed. Generally, photographers should adjust a camera exposure properly for obtaining an image with real color tone of subjects. Thus, in case of taking a picture under a dim light condition, the exposure time of a camera has to be relatively longer than the one under a bright light condition. Although images with real color tone of the subject are obtained, the images may get blurred due to the shaky hands of photographer holding the camera. In order to avoid the blur effect, an input image is captured from a camera set as a short exposure time under a dim light condition. Then we propose a method to reproduce color tone of the dim input image. To this end, color variation characteristics which represent color variations of a digital camera are first extracted by analyzing the Macbeth color checker images taken under various exposure values. Then, a color reproduction is performed by an estimation based on the color variation characteristics. Experimental results have shown that the proposed method has achieved better performance of color reproduction, compared with existing methods.
