Abstract:
본 고안은 칼라계의 디스플레이를 위한 칼라 비교 리스트에 관한 것으로, 색조 시트(hue sheet)는 색조 서클에 의해 점차적으로 높은 색도로 외측으로 연장하는 중앙의 표준 회색에 의해 나타나며, 각 색조 서클(색도 링)의 칼라는, 낮은 색도에서 높은 색도로 6 배수의 칼라 넘버(칼라 블록)만큼 차례로 증가한다. 더욱이, 색조 시트에서 소정의 색도의 색조 서클에 있어서, 동일한 공간(3개의 칼라, 혹은 동일 공간에서 3 배수의 칼라야 함)에 있는 칼라의 혼합만이 표준 회색, 즉 색조 시트의 중앙 칼라가 될 것이다. 색조 시트의 중앙 칼라는 각각의 색조 서클의 어떠한 위치에 있는 칼라 블록까지 동일한 거리를 유지한다. 더욱이, 칼라 솔리드의 각 색조 시트는 심도를 달리하여 위에서 아래로 배열되어 있다. 결과적으로, '색조 비교 리스트' 와 '심도 비교 리스트' 는 연속적인 시각적 효과와 우수한 3-D 칼라 공간을 생성하였다. 이는 또한 정량화를 위한 참조로서 사용할 수도 있다.
Abstract:
PURPOSE: A method and an apparatus for detecting a temperature of an illumination color are provided to extract a stable and effective illumination information. CONSTITUTION: A method for detecting a temperature of an illumination color includes six steps. A first step is to select an image and find an RGB mean vector value as calculating a mean value by a channel of each RGB for the image. A second step is to define a predetermined coefficient f which is a larger positive number than 1 and estimate f times of the RGB mean vector value as a temporary illumination color for an image selected. A third step is to estimate the closest illumination color to a temporary estimation illumination color as an illumination color on a sunlight orbital. A fourth is to establish k times of an estimating illumination color as a self light emitting threshold value. The k is a predetermined coefficient and is a larger positive value than 1 A fifth step is to generate an image which a self light emitting area is removed as removing the self light emitting area having a larger RGB value than the self light emitting threshold value. A sixth step is to calculate and output an illumination color temperature from the UV chromaticity value of an image which the self light emitting area is removed.

Abstract:
A color reproduction system and a method thereof are provided to predict a scaling parameter and to determine final brightness and freshness of pixels in order to enable various color production by a user even if the same image is applied to displays having different sizes. A color reproduction system comprises an image content analysis unit(152), a parameter prediction unit(154), and a brightness-freshness determining unit(156). The age content analysis unit analyzes the color distribution of pixels. The parameter prediction unit predicts a scaling parameter based on attribute information on the pixels, the color distribution, and image size information. The brightness-freshness determining unit determines the final brightness and the freshness of the pixels, using the predicted parameter. The attribute information includes the brightness and freshness of the pixels, and the color information.
Abstract:
The present invention is directed to a method and device that use spectral measurements of the color of a target coating on a substrate, such as auto body being matched. The method utilizes pigment mixture models to produce a matched coating composition that when applied as a coating matches in appearance with that of the target coating, while also providing other desired coating properties, such as durability, gloss and adhesion. Various colorant combinations are analyzed to produce approximate spectral curves that substantially match the spectral curve of the target color. A colorant optimization function is then used to identify the optimum formula. This function utilizes acceptability factors, such as closeness of match based on a color tolerance formula, metamerism indices, shape of spectral curves, cost, and pigment durability. Each factor is weighted according to the specific end-use of the composition. The method of the present invention is well suited for producing automotive refinish paints used in automotive refinish applications wherein the undamaged portion of the autobody is color matched to produce a matched refinish paint that can be then applied over a repaired portion of autobody.
