PROBLEM TO BE SOLVED: To provide a method for easily and objectively evaluating a texture.SOLUTION: A texture evaluation method includes: (1) a process for capturing an enlarged image of a skin of a subject, creating a visual observation score, and calculating texture parameters Sa, PSm, and Str (2) a process for obtaining a multiple regression equation using the visual observation score as an objective variable, and the texture parameters Sa, PSm, and Str as explanatory variables and (3) a texture evaluation process for evaluating a theoretical value of a texture score of the subject by texture parameter arithmetic values Sa1, PSm1, and Str1 calculated from the enlarged image of the skin of the subject in the same way as (1), and the multiple regression equation.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】肌理を簡便かつ客観的に評価する方法を提案する。【解決手段】(1)複数者の肌について拡大画像を撮像し、目視スコアを作成し、肌理パラメータSa’、PSm’、Str’を算出する工程(2)前記目視スコアを目的変数、前記肌理パラメータSa’、PSm’、Str’を説明変数とする重回帰式を求める工程(3)被験者の肌の拡大画像から前記(1)と同様にして算出した肌理パラメータ演算値Sa1、PSm1、Str1と前記重回帰式より、前記被験者の肌理スコア理論値を評価する肌理評価工程を有する肌理評価方法【選択図】図1
