PROBLEM TO BE SOLVED: To provide a method for measuring the amount of skin sag, and a method for evaluating a cosmetic or the like by using the method.SOLUTION: A method for evaluating the amount of skin sag by analyzing images of both horizontal and vertical positions of a subject is provided. In the method, a measurement point is set when imaging the horizontal position, and a measurable object having measurable means is applied an area around the measurement point so that it is at the center of the area. With use of the measurable object, three-dimensional numerical data on displacement distance of each measurement point that is obtained by superimposing the image of vertical position on the image of the horizontal position can be analyzed on two-dimensional plane, so that the actual amount of skin sag can be measured easily and directly.COPYRIGHT: (C)2014,JPO&INPIT【課題】皮膚のたるみ量を測定する方法、及び当該方法を用いた化粧品等の評価方法を提供する。【解決手段】水平位、垂直位の2姿勢の画像を解析することでたるみ量を評価する方法において、水平位の画像撮影時に測定点を設定し、さらにその測定点を中心として、その周りを囲むように計測手段を備えた測定具を適用し、水平位、垂直位の2姿勢の画像を重ね合わせた際に得られる各測定点の変移距離を、前記測定具を用いることで、三次元的な数値を簡便にニ次元平面上で解析できるようにし、より簡便かつ直接的に皮膚のたるみ量の実測値を測定する。【選択図】図1
