1. A skin gloss evaluation device comprising:
- an image input unit that inputs a captured image obtained by imaging a face of a subject;
an analysis range setting unit that sets a portion in which it is easy for gloss of skin of the subject to occur and a portion in which it is difficult for gloss to occur in the captured image as analysis ranges;
a skin evaluation index calculation unit that calculates a skin evaluation index related to the set of analysis ranges; and
a luster and oiliness evaluation unit that evaluates luster and oiliness of the face of the subject on the basis of the skin evaluation index,wherein the skin evaluation index calculation unit calculates, as the skin evaluation index, a chroma difference between the portion in which it is easy for the gloss of the face of the subject to occur and the portion in which it is difficult for gloss to occur that are set as the analysis ranges, andthe luster and oiliness evaluation unit classifies and evaluates luster and oiliness on the basis of the chroma difference.

Abstract
The present invention provides a gloss evaluation device, a gloss evaluation method, and a non-transitory computer readable recording medium storing gloss evaluation program capable of evaluating gloss of skin easily and highly accurately. In the gloss evaluation device of the present invention, a skin evaluation index calculation unit 5 calculates, as a skin evaluation index, a chroma difference between a portion in which it is easy for the gloss of the face of the subject to occur and a portion in which it is difficult for gloss to occur that are set as analysis ranges, and a luster and oiliness evaluation unit 6 evaluates luster and oiliness on the basis of the chroma difference.
