    摘要: A skin color measurement system comprises: a transformation module which transforms the color of an image obtained by photographing a skin into color data in a log coordinate system having coordinate axes corresponding to primary colors; a first measurement module which disposes a preset illumination vector and a plurality of pigment vectors in a polygonal cone shape surrounding the color data, and measures a yellowish tone using the position of the vertex of the polygonal cone; and a second measurement module which separates the color data into the directional component of the illumination vector and the directional component of each of the pigment vectors, and measures a plurality of pigment distributions. With the skin measurement system, it is possible to measure a yellowish tone, a blackish tone and/or a reddish tone of a skin, and to output a result of the measurement as an image, and thus it is possible to simply and visibly express a change in a skin tone before and after a specific makeup product is used.
