Color reproductions in most ink jet printer are quite different from that of standard CRT (cathode ray tube) monitor display because of the nonlinear characteristic in subtractive color reproduction. Gray scale CCT(correlated color temperature) reproductions in a typical printer are vary with the input RGB level. A simple method for making constant gray scale CCT and gamma value in photo paper is proposed in this paper. The compensation of the CCT with white point of the photo paper under the CIE standard illuminant D65 and color correction has been confirmed using the LUT(look-up table) to compensate the CCT and gamma curve characteristic.

The standard stellar models for HIP 20916 and HIP 101769 have been constructed to determine the properties of the binary system. Augmented with speckle data which is the magnitude difference between stars of the binary system, the previously determined parameters, such as [Fe/H], distance, total mass, and etc, are used to construct the standard stellar models. And the Green table is used to convert L and $T_{eff}$ into $M_v$ and color for comparison between models and observational data. We present the constructed stellar models of the system.

This study is designed to investigate the properties of caramel color made by corn sugar molasses, a new material. Com sugar refined and then caramelized in the solution of pH 2-10 ranges using catalysts such as ammonium carbonate, glycine and lysine. The control solution are 10% hydrochloric acid and sodium carbonate. The result were as follow; The caramelization showed the intensity of very strong color when added 0.4% ammonium carbonate as a catalyst. Color hue appeared to have the same color hue of the yellow belt and the red belt when compared with standard color hue in alkali, but the samples blue belt in all pH ranges showed a strong color hue than the standard color hue. Also, the stability of tannin, table salt and alcohol was transparent in all pH ranges, but the stability of acid appeared hazy at pH 9-10. In the case of glycine as a catalyst, caramelization showed the intensity of strong color when added 0.8% glycine at pH 9. Color hue showed in the yellow belt, strong in the red belt and very strong in the blue belt in all pH ranges when compared with standard color hue. Stability of tannin, table salt, acid alcohol was quite stable. In the case of lysine as a catalyst, caramelization showed strong color intensity when added 0.4% lysine in pH 9. Stability of tannin, table salt, acid and alcohol was quite stable.

We focus our attention on grading of table meat in accordance with the standard of Japan Meat Grading Association, and construct a beef grading system by image processing. For image processing of beef grading, it needs some techniques such as a shading correction, separation of color image data, and classification of color image data into some grades, for the system construction. However, there are various kinds of weak points in usually used methods for these techniques. Then the authors propose and introduce new approaches using Neural networks and fuzzy inference for the techniques above mentioned, which is very convenient and ensure the high precision.

Purpose: This study aims to develop menu for tofu, which will satisfy a variety of needs of people by harmonizing tofu and other ingredients. Methods: In the present study, the standard recipes were made for tofu menu development by improving the existing recipes like Dubu-seon, Dubu-kimchi, Dubu-jeongol, and Sundubu-jjigae (soft tofu stew). Based on newly developed recipes, the nutritional analysis was conducted using the analyzing program of the Korean Nutrition Society (CAN-Pro 4.0). Food styling was devised considering the shape and color of plates, layout, and color harmony. Table design was devised empirically employing tablecloth, napkin, dinnerware, glasses, cutlery, centerpiece, and figures. Results: Food styling of Dubu-seon was devised by improving the visual aspect, using Korean traditional five cardinal colors. It turns out that the improvised version of Dubu-seon (prepared following the new recipe) can satisfy 15.1% of amount of recommended dietary fiber intake per day for both male and female adults. In case of Dubu-kimchi, the dish was developed as a one-dish meal by supplementing protein and improving food styling. Beef was added in a form of a meatballs which is especially preferred by children. However, the amount of salt was reduced due to the strong and spicy taste of kimchi itself, resulting in 32% of daily intake of sodium. Dubu-jeongol was also improvised by reducing protein content, and more vegetables were added. Food styling was also improved. Concerning Sundubu-jjigae, protein was supplemented by addition of mushrooms rather than the existing way of adding shellfish. The sodium content was 133.88 mg, which is merely 10% of daily intake. Conclusion: With the new developments in tofu menus, new food styling, and table design, this study aims to contribute towards the rise in sales in the food service industry in terms of being used as basic and critical data.

The leaf persisting and seasonal leaf color characteristics of deciduous woody landscape plants were investigated through the field survey in Suwon region. The leaf period was about 270 days from March 20, 1992 when Prunus padus was leaf spreading to December 17, 1992 when Lonicera sempervirens was leaf falling. The plants of leaf period over 240 days were Elaegagnus umbellata var. coreana, Salix pseudo-lasiogyn, Ligustrum obtusi-folium, Rosa multiflora, Lonicera sempervirens and Clematis viticella. The woody landscape plants bearing the red leaf by KBS standard color number before fall foliage coloring were Prunus salicina, Berberis thunbergii 'Atropurpurea', Acer platanoides 'Red King', Acer palmatum var. Pendula 'Crimson Queen', Parthenocissus tricuspidata, Nyssa sylvatica, Acer palmatum var. sanguineum, and the yellow leaf, Berberis thunbergii Variegata 'Aurea', Physocarpus opulifolius 'Luteus', and Forsythia koreana 'Seoul Cold', Ligustrum X vicaryi which is variegation. The fall foliage color period was about 100 days from September 6, 1992 when Euonymus alatus was fall foliage coloring, to December 17, 1992 when Lonicera sempervirens was leaf falling. (Table 24) And in terms of color based on KBS standard color number, 60.7% of fall foliage were yellow, 37.4%, red, respectively.

This paper proposes an improved six-color separation reducing the graininess in a middle tone region based on the standard deviation of the lightness and chrominance in S-CIELAB space. Graininess is regarded as visual perception for the fluctuation of the lightness of the light cyan and cyan or light magenta and magenta. In the conventional methods, the granularity is extremely heuristic and inaccurate due to the use of the visual examination score. Accordingly, this paper proposes a method to calculate the objective granularity for six color separation. First, we use the lightness, redness-greenness, and yellowness-blueness of the S-CIELAB space reflecting the spatial-color sensitivity of the human and normalize the sum of the three standard deviations. Finally, we apply the proposed granularity to the six color separation after assigning the granularity to the lookup table and obtain the result reducing the graininess in a middle tone region.

This paper proposes the color decomposition method for multi-primary display (MPD) using a 3-dimensional look-up-table (3D-LUT) in a linearized LAB space. The proposed method decomposes conventional three-primary colors into the multi-primary control values of a display device under constraints of tristimulus match. To reproduce images on the MPD, the color signals should be estimated from a device-independent color space, such as CIEXYZ and CIELAB. In this paper, the linearized LAB space is used due to its linearity and additivity in color conversion. The proposed method constructs the 3-D LUT, which contain gamut boundary information to calculate color signals of the MPD. For the image reproduction, standard RGB or CIEXYZ is transformed to the linearized LAB and then hue and chroma are computed to refer to the 3D-LUT. In the linearlized LAB space, the color signals of a gamut boundary point with the same lightness and hue of an input point are calculated. Also, color signals of a point on gray axis are calculated with the same lightness of an input. With gamut boundary points and input point, color signals of the input points are obtained with the chroma ratio divided by the chroma of the gamut boundary point. Specially, for the hue change, neighboring boundary points are employed. As a result the proposed method guarantees the continuity of color signals and computational efficiency, and requires less amount of memory.
