현대생활에서 색채가 갖는 중요성은 점차 증가일로이고, 그런 현대를 컬러 에이지라는 말로 표현한다. 생활의 모든 영역이 패션 화 되어가고 있는 요즘은, 디자인 전문가뿐만 아니라 일반인들에게도 색채에 대한 교양과 지식이 요구되고 있다. 또한, 색채는 인간 감성에 미치는 즉각적인 소구력이 형태보다도 크므로, 마케팅의 중요한 판매요인이 되기도 한다. 그러므로 색채디자인 교육은 교양과정에서도, 전문적인 디자인 교육과정에서도 매우 중요한 커리큘럼이다. 색채는 색상.명도ㆍ채도의 삼속성으로 표현한다. 그러나 디자인현장에서의 색채는 명도와 채도의 복합개념인 톤을 사용한, 휴 앤드 톤 컬러 시스템을 주로 사용하고 있다. 그러므로 색채디자인의 교육에서도 색상은 물론, 명도와 채도를 합한 개념인 톤을 교육하는 것이 매우 중요하다고 생각된다. 그러나 국내에는 휴 앤드 톤으로 이루어진 컬러 시스템의 연구가 아직 미흡하다. 따라서 색채디자인의 교육현장에서도 외국의 컬러 시스템을 교육하고, 배색교육에 있어서도 수입된 색지를 주로 사용하고 있다. 색채의 증가하는 영향력을 생각할 때, 국내에서도 색채디자인 교육에 적합한 휴 앤드 톤의 컬러 시스템을 개발하고, 그에 의거 한 색채디자인용 색지를 개발하는 것은 매우 시급한 과제라고 생각된다. 본 연구에서는 이러한 색채디자인교육의 효율화를 위한 한 시도로서, 일반적인 색채디자인교육에 활용할 수 있는 $\ulcorner$휴 앤드 톤 253 색체계$\lrcorner$를 설계하였다.

It is very important to inspect the color of printed texture in the textile process. The standard colorimetric system used for the recognition of the color in the textile industry. It uses XYZ color system defined by CIE (Commission Internationale de 1Eclairage), but is too expensive. Therefore, in this paper, we propose a color inspection system of the printed texture using a color scanner. Because the scanner uses RGB value for color, it is necessary the mapping from RGB to XYZ. However, the mapping is not simple, and the scanner has even positional deviation because of the geometric characteristics. To transform from RGB to XYZ, we used a NN (neural network) model and also compensated the positional deviation. In real experiments, we could get fairly exact XYZ value from the proposed color inspection system in spite of using a color scanner with large measuring area.

The color measuring/matching expert system is implemented with a new color measuring method that combines intelligent algorithms with image processing techniques. Color measuring part of the proposed system preprocesses the scanned original color input images to eliminate their distorted components by means of the image histogram technique of image pixels, and then extracts RGB(Red, Green, Blue)data among color information from preprocessed color input images. If the extracted RGB color data does not exist on the matching recipe databases, we can measure the colors for the user who want to implement the model that can search the rules for the color mixing information, using the intelligent modeling techniques such as fuzzy inference system and adaptive neuro-fuzzy inference system. Color matching part can easily choose images close to the original color for the user by comparing information of preprocessed color real input images with data-based measuring recipe information of the expert, from the viewpoint of the delta Eformula used in practical process.

Recent beauty trends focus on suitability to individual features. A personal color system is a recent aesthetic concept that influences color make up and coordination. However, a personal color concept has several weaknesses. For example, type classification is qualitative and not quantitative because its measuring system is a sensory test with no industry standard of personal color system. A quantitative personal color type classification model is the purpose of this study, which can be a solution to above problems. This model is a kind of mapping system in a 3D Cartesian coordinate system which has own axes, Value, Saturation, and Yellowness. The cheek color of the individual sample is also independent variable and personal color type is a dependent variable. In order to construct the model, this study conducted a colorimetric survey on a 993 sampling frequency of Korean women in their 20s and 30s. The significance of this study is as follows. First, through this study, personal color system is established on quantitative color space; in addition, the model has flexibility and scalability because it consisted of independent axis that allows for the inclusion of any other critical variable in the form of variable axis.

Presented herein is a novel stereoscopic three-dimensional (3D) display system with active color filter glasses. This system provides full-color 3D images by applying the time-multiplexing technique on the original anaglyph method. By switching between the opposite anaglyph statuses, a full-color anaglyph is presented. A liquid crystal panel from a 3D monitor serves as an active color filter operating at 120 Hz. A display panel and a color filter are connected to one graphic card as a dual-link system, for synchronization. To test the quality of this system, a left/right-eye image separation test and an experiment with stereoscopic images were carried out. Although there was some crosstalk and blur, the system, as expected, provided full-color 3D display. This system overcomes a monochromatic 3D image, which is the major weakness of the original anaglyph system.

본 연구는 모바일 앱 배색을 위한 색채 추천 시스템의 활용을 위한 연구이다. 이를 위해 선택 색상에 조화되는 색채를 자동으로 추천해주는 머티리얼 시스템과 모바일 웹 앱의 3 배색을 모바일 앱 디자인에 적용하여 배색 실험을 하였다. 그리고 두 가지 방법의 실험에 대한 설문으로 색상 구성과 선택 색상, 결과물의 만족도에 관한 정도를 리커트 7점 척도로 알아보았고, 결과물에 따른 배색 특징을 비교하여 분석하였다. 머티리얼 컬러 팔레트는 정해진 색상의 규칙적인 색조 단계를 자동으로 시스템화하여 색상 선택을 쉽게 하였지만, 모바일 웹 앱 3 배색인 주조색, 보조색, 강조색에 대한 색상 구성과 색상 범위가 다르며, 프라이머리 컬러와 세컨더리 컬러만 선택 가능하여 디자인에 따라 강조색의 선택 기능이 필요했다. 또한 머티리얼 시스템은 색상 범위와 배색 범위가 정해져 있기 때문에 유채색의 사용이 많았고, 대비가 큰 색조나 보색을 선택해도 배색 범위에 따라 배색 결과물의 이미지가 달라져서 배색 범위에 따른 색상 구성의 역할이 중요했다.

CCD Camera System으로 capture 한 image를 표준 display장치로 재현할 때 capture 할 당시의 원 피사체의 모습을 그대로 재현하여야만 한다. 그러나 일반 consumer 용 camera system의 CCD channel spectral sensitivity 특성이 인간의 spectral sensitivity(1(λ), m(λ), 5(λ)) 특성과 일치하지 않고, linear transform의 관계도 성립하지 않음으로써 capturing시 근본적인 color error가 발생하게 된다. 기존의 CCD Camera System 에서는 CCD sensor 의 color 정보와 display 장치의 color 정보와의 단순한 산술적인 관계로 color를 재구성하는 방법을 사용하고 있어 원 피사체의 color 를 그대로 재현할 수가 없다. 본 논문에서 제시하는 알고리즘은 CCD 의 channel spectral sensitivity특성 과 CIE-color matching function과의 관계를 고려하여 color를 재구성함으로써 color error를 줄이도록 하였다 제시된 알고리즘의 color error를 검증하기 위하여 물체의 고유반사율을 알고 있는 AGFA IT8.7-2 test chart(283 spectra), Dupont Paint Chips(120 spectra), Mcbeth Color Checker(64 spectra) 및 Natural Objects(170 spectra) 등 다양한 objects spectra(637 spectra) [1][2]를 이용하여 기존 방법의 알고리즘과 비교하여 보았다.

In the agricultural field, a machine vision system has been widely used to automate most inspection processes especially in quality grading. Though machine vision system was very effective in quantifying geometrical quality factors, it had a deficiency in quantifying color information. This study was conducted to evaluate color of beef using machine vision system. Though measuring color of a beef using machine vision system had an advantage of covering whole lean tissue area at a time compared to a colorimeter, it revealed the problem of sensitivity depending on the system components such as types of camera, lighting conditions, and so on. The effect of color balancing control of a camera was investigated and multi-layer BP neural network based color calibration process was developed. Color calibration network model was trained using reference color patches and showed the high correlation with L*a*b* coordinates of a colorimeter. The proposed calibration process showed the successful adaptability to various measurement environments such as different types of cameras and light sources. Compared results with the proposed calibration process and MLR based calibration were also presented. Color calibration network was also successfully applied to measure the color of the beef. However, it was suggested that reflectance properties of reference materials for calibration and test materials should be considered to achieve more accurate color measurement.
