Abstract: A color conversion method, medium, and apparatus, converting a color temperature of an image to a user-set color temperature, on a pixel-by-pixel basis, based on the brightness of each pixel of the image. The color temperature conversion method may include determining a first information associated with a conversion range, determining whether the color temperature of the input pixel needs to be converted by determining, based on the first information, whether the input pixel is within the conversion range, calculating color coordinates of a target point if the input pixel is within the conversion range, and converting the color temperature of the input pixel by moving, in the same direction as the reference point to the target point an amount proportional to the reference point displacement so that the input pixel can be automatically moved along with the reference point of the conversion range.
Abstract translation: 基于图像的每个像素的亮度，以逐个像素为基础的颜色转换方法，介质和装置，将图像的色温转换为用户设定的色温。 色温转换方法可以包括确定与转换范围相关联的第一信息，通过基于第一信息确定输入像素是否处于转换范围内，确定是否需要转换输入像素的色温，计算 如果输入像素在转换范围内，则目标点的颜色坐标，并且通过以与基准点相同的方向将与参考点位移成比例的量移动到与基准点相同的方向来转换输入像素的色温，使得 输入像素可以与转换范围的参考点一起自动移动。

Abstract: An apparatus, medium, and method for correcting color of an image. The apparatus may includes a user interface which displays each of N reference patches, removes non-gray components from the displayed N reference patches, according to the characteristics of a user's visual system, and outputs the reference patches from which the non-gray components have been removed as adjusted reference patches, a table generator which generates at least one lookup table that has, as addresses, color component values for a current image and stores color component values of the adjusted reference patches as data, and a color corrector which addresses the at least one lookup table using the color component values of the image to read data corresponding to correction information for the color component values of the image and outputs the read data as the result of the correcting of color of the image.
