Abstract: A color translation method and a color translation apparatus adapted to map a data point from a first color space to a second color space are provided. At least four color axes coordinating with a plurality of first reference points and a plurality of second reference points corresponding to the first reference points are used to divide the first color space and second color space into a plurality of first sub-spaces and a plurality of second sub-spaces. A target first sub-space where the data point is located is found, and then a corresponding target second sub-space is also found. According to a positional relationship between the data point and the first reference points which define the target first sub-space, an interpolation operation is applied to the second reference points which define the target second sub-space so as to obtain a mapped point in the second color space.

Abstract translation: 提供了一种适于将数据点从第一颜色空间映射到第二颜色空间的颜色翻译方法和颜色翻译装置。 使用与多个第一参考点协调的至少四个颜色轴和对应于第一参考点的多个第二参考点将第一颜色空间和第二颜色空间分成多个第一子空间和多个 第二个子空间。 找到数据点所在的目标第一子空间，然后找到相应的目标第二子空间。 根据定义目标第一子空间的数据点和第一参考点之间的位置关系，对定义目标第二子空间的第二参考点应用内插操作，以获得目标第二子空间中的映射点 第二色空间。
