<p><P>PROBLEM TO BE SOLVED: To provide an art for estimating the amount of sebum skin using near-infrared diffuse reflectance spectrum. <P>SOLUTION: This estimation method estimates a recovery amount of sebum skin by (1) a step for previously measuring the near-infrared diffuse reflectance spectrum of two types or more skins under different conditions and acquiring a correlation between the amount of sebum skin and the amount of sebum estimated value acquired from an analysis result of a multivariate analysis based on the analysis result of a multivariate analysis between the spectrum data and the sebum quantities of the skins, (2) a step for acquiring the near-infrared diffuse reflectance spectrum of the skin, or the estimation target, whose amount of sebum is unknown, and (3) a step for estimating the amount of sebum skin of the estimation target by the near-infrared diffuse reflectance spectrum acquired in the (2) based on the correlation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
