AI Technical Summary

Technical Problem

Conventional methods for evaluating skin texture are limited to assessing the degree of gloss and lack accuracy in evaluating the overall texture of the skin.

Method used

A skin evaluation device that calculates the intensity and uniformity of specularly reflected light and the intensity of subsurface scattered light to evaluate skin texture, using a combination of a light source, imaging device, and a calculation unit to separate and analyze these optical properties.

Benefits of technology

Improves the accuracy of skin texture evaluation by considering multiple optical properties, enabling classification into different skin types and estimating skin conditions and age appropriateness.

Abstract

The present invention improves the accuracy of evaluating the texture of skin. A skin evaluation device according to an embodiment of the present invention evaluates the texture of a subject's skin, and comprises: a calculation unit that calculates the intensity of specularly reflected light specularly reflected on the surface of the skin due to the radiation of light, the uniformity of the specularly reflected light, and the intensity of subsurface scattered light emitted to the outside of the skin after being scattered inside the skin due to the radiation of the light; and an evaluation unit that evaluates the texture of the skin on the basis of the intensity of the specularly reflected light, the uniformity of the specularly reflected light, and the intensity of the subsurface scattered light.
