    • An apparatus and method of reproducing a preferred color to eliminate or reduce errors caused when converting of colors of an input image in corresponding color regions of a color space, respectively, wherein the colors of an input image are included in a plurality of different color regions. The apparatus includes a region judging unit to judge whether pixels of an input image are included in one or more preset color regions, a color converting unit to execute a color conversion of the pixels in at least one conversion-desired color regions among one or more color regions that include the pixels, and an output unit to output an image formed by the color-converted pixels.
    • 一种再现优选颜色以消除或减少在颜色空间的相应颜色区域中分别输入图像的颜色转换时引起的错误的装置和方法,其中输入图像的颜色被包括在多个不同的颜色区域中 。 该装置包括区域判断单元,用于判断输入图像的像素是否包含在一个或多个预设颜色区域中;颜色转换单元,用于执行至少一个转换期望颜色区域中的像素在一个或多个中的颜色转换 包括像素的彩色区域和输出由颜色转换像素形成的图像的输出单元。

    • A method and apparatus for enhancing the quality of images using complementary color contrast are provided. The method includes (a) extracting color information of each of a plurality of pixels of an input image, (b) determining whether the input image includes both a first pixel belonging to a first group and a second pixel belonging to a second group with reference to the extracted color information, (c) converting a first hue of the first pixel into an optimum point of the first group, and (d) converting a second hue of the second pixel into an optimum point of the second group, wherein the first hue corresponding to the optimum point of the first group and the second hue corresponding to the optimum point of the second group are complementary to each other.
    • 提供了一种用于增强使用互补色对比度的图像质量的方法和装置。 该方法包括(a)提取输入图像的多个像素中的每一个的颜色信息,(b)确定输入图像是否包括属于第一组的第一像素和属于具有参考的第二组的第二像素 提取颜色信息,(c)将第一像素的第一色调转换为第一组的最佳点,以及(d)将第二像素的第二色调转换为第二组的最佳点,其中第一组 对应于第一组的最佳点的色调和对应于第二组的最佳点的第二色调彼此互补。

    • A method and apparatus for an image adaptive color adjustment of pixels in a color gamut is disclosed. The method includes calculating a representative value that shows color characteristics of pixels included in a color gamut, calculating a final target color required to convert the representative value to approach a reference target point existing in the color gamut, and converting the pixels included in the color gamut to approach the final target color. The apparatus includes a color gamut boundary storage module; a reference target point storage module; a target color determination module which calculates a representative value that shows color characteristics of pixels included in a color gamut and calculates a final target color required to convert the representative value to approach the reference target point; and a color conversion module which converts the pixels included in the color gamut to approach the final target color.
