A purpose of this study is to 6nd out how the casual and formal style clothes of stripe pattern giving variety by pattern direction, pattern width, and contrast coloration have an effect on image of wearers. For this, 192 stimuli were made and 1200 testee evaluated them using semantic differential scale. As a result, five image dimensions were drawn as a factor of attractiveness, gracefulness, activeness, visibility, and tenderness. Unlike the value contrast previously researched, it showed that chroma contrast coloration which was interacted with a color tone contrast coloration had an effect on all the 5 image dimensions. This result was recognized as significant clothes dues in evaluating the image of stripe wearers. Besides, clothing style, stripe pattern, and contrast coloration were made clear as an efficient parameter in image presentation of clothing wearers.

This study aimed to investigate and analyze the overall color utilization characteristics as design elements of advanced men's premium outer brands. From the analysis of a total of 889 color samples, PB showed the highest distribution in color, Bk, R, and P. The use of ltg and p of high and low chroma was high, centering on dkg of low value and low chroma, and g of medium chroma. The men's premium outer brand displays a luxurious color image centered on color planning due to color contrast between dark and grayish shades. The characteristics of colors and color distribution by brand were considered. The brands that utilized the most diverse colors and shades were Herno, which pursues sportswear of the Elegance image, and Stone Island, which pursues casual images of workwear style. These results show that systematic planning using colors and shades are utilized by all premium outer brand concept. The results of this study are meaningful because they can be used as basic data for effective product planning, men's outer design development, and color planning of outer clothing brands are they represent premium outer brands for men, and identifies color characteristics as differentiated design elements.

In general, methods based on histogram or a correction of gamma curve are usually utilized to enhance the contrast of captured image in the dark scene. These methods are efficient to enhance the contrast globally, however, they locally induced the low quality of image. Recently, to resolve the problem, the multi-scaled refiner algorithm improving the contrast with locally averaged lightness is proposed. However, estimating the locally averaged lightness, if there is the object with a high saturated color, the color distortion might be induced by the color of object. Thus, in this paper, the dominant chromaticity of image is estimated to correct the locally averaged lightness in multi-scaled retinex algorithm. Because the average chromaticity of image includes the chromaticity of illumination, the dominant chromaticity is estimated with dividing the average chromaticity of image by the estimated chromaticity of illumination from highlight region. In addition, to improve the lower chroma by multi-scaled retinex algorithm generally, the chroma was compensated preserving the hue in the CIELAB color space.

The purpose of this study is to explore how people's evaluation and preference on color palettes differ based on their cultural background. This study used the same color palettes developed by Youngsoon Park and Denise Guerin(1992). Fourteen representative adjectives are used to analyze the meaning evaluation and preference on the six color palletes. 425 undergraduate students are se-lected from Korea, Japan, U.S. and England and ques-tionnaire was used as survey instrument. The results show that there are significant differences among the four countries in the meaning evaluation and preferences on the color palettes and the characteristics of color palettes influence the differences among the countries. The differences among the countries decrease in case of color palettes composed of warm color with low or medium value difference and chroma difference, while the differences increase in case of color palette characterized by strong color contrast with high or medi-um value difference and chroma difference. The result of color meaning evaluation can be catego-rized into Western and Eastern culture. Korea and U.S., and Japan and U.S. showed significant differences in the most words and Korea and Japan showed similarities in the most words. Therefore it can be concluded that cul-tural backgrounds related to race, region and history in-fluence the color meaning evaluation and preference. Fur-ther study should explore the relationship between color and culture using more various color instruments such as color palettes in order to categorize the various aspects of culture.

Recently the CPU performance of modem chipsets or multimedia processors of mobile phone is as high as notebook PC. That is why mobile phone has been emerged as a leading ICON on the convergence of consumer electronics. The various applications of mobile phone such as DMB, digital camera, video telephony and internet full browsing are servicing to consumers. To meet all the demands the image quality has been increasingly important. Mobile phone is a portable device which is widely using in both the indoor and outside environments, so it is needed to be overcome to deteriorate image quality depending on environmental light source. Furthermore touch window is popular on the mobile display panel and it makes contrast loss because of low transmittance of ITO film. This paper presents the image enhancement algorithm to be embedded on image enhancement SoC. In contrast enhancement, we propose Clipped histogram stretching method to make it adaptive with the input images, while S-shape curve and gain/offset method for the static application And CIELCh color space is used to sunlight readability enhancement by controlling the lightness and chroma components which is depended on the sensing value of light sensor. Finally the performance of proposed algorithm is evaluated by using histogram, RGB pixel distribution, entropy and dynamic range of resultant images. We expect that the proposed algorithm is suitable for image enhancement of embedded SoC system which is applicable for the small-sized mobile display.

Multi-scaled retinex algorithm is generally used to enhance the local contrast and remove the illuminant component. However, if the chromatic distribution of an original image is not uniform and dominated by a certain chromaticity, the chromaticity of resulting image depends on the dominant chromaticity of the original image, thereby inducing the color distortion. In this paper, a modified multi-scaled retinex method to reduce the influence of the dominant chromaticity in the image is proposed using a average chromaticity of original image and global illuminant chromaticity. In addition, to compensate saturation, the chroma value of the resulting image is enhanced based on that of the original image in the CIELAB space.
