Color translation method and color translation apparatus

摘要

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.

1. A color translation method adapted for a color translation apparatus to map a data point from a first color space to a second color space, the color translation apparatus comprising an operating unit and a memory coupled to the operating unit, the method comprising:
obtaining a plurality of first reference points in the first color space stored in the memory by the operating unit of the color translation apparatus and using at least four color axes coordinating with the plurality of first reference points in the first color space to divide the first color space into a plurality of first sub-spaces by the operating unit; using the at least four color axes coordinating with a plurality of second reference points in the second color space corresponding to the first reference points to divide the second color space into a plurality of second sub-spaces by the operating unit; finding a target first sub-space where the data point is located in the first sub-spaces, and finding a target second sub-space corresponding to the target first sub-space in the second sub-spaces by the operating unit; and according to a positional relationship between the data point and the first reference points defining the target first sub-space in the first color space, applying an interpolation operation to the second reference points defining the target second sub-space by an interpolator of the operating unit, so as to obtain a mapped point of the data point in the second color space.
