PROBLEM TO BE SOLVED: To provide a novel method of evaluation capable of numerically evaluating various properties of the skin such as the degree of strain, direction of strain, moisture, stickiness, sheen, smoothness, and tension, in addition to the resilience, softness and looseness.SOLUTION: The change of the surface of the skin caused by external force in a short period of time is photographed by a high-speed camera and the change of the state of the skin surface appearing in the image taken by the camera is image-processed, which is analyzed to evaluate the properties of the skin. As for the application of the external force, compressed gas etc. is jetted to a part for evaluation on the skin surface.COPYRIGHT: (C)2007,JPO&INPIT【課題】弾力性、柔軟性、弛み度の他に、つっぱり度、つっぱり方向、潤い感、べとつき感、つや、滑らかさ、はり等の種々の皮膚性状を数値的に評価することを可能とする新たな評価手法を提供する。【解決手段】外力による皮膚表面上の短時間の変化を高速度カメラで撮影し、その画像に現れる皮膚の表面状態の変化を画像処理により解析して皮膚性状を評価する。外力の付加方法としては、皮膚表面の評価部位への圧縮ガスの噴射等を行う。【選択図】図1
