PROBLEM TO BE SOLVED: To provide a method and a device capable of objectively and sequentially evaluating the presence/absence and magnitude of a hair restoration effect on eyelashes and the effect of improving decorativeness of the eyelashes by mascara, treatment for the eyelashes, an eyelash beauty liquid, various kinds of supplements, food and drink or the like.SOLUTION: In the analyzing method of eyelashes and the analyzer therefor, on the basis of a correction image in which an image of an eye to be analyzed is segmented from a black-and-white photograph of closed eyes and the image is corrected such that a histogram by brightness is distributed and spread from the darkest value to the brightest value in a horizontal axis direction, measurement of the length of the longest eyelash, preparation of a binary image and the histogram, line scan on the eyelashes, output of time sequential signals in which a horizontal axis is the time and a vertical axis is the brightness (luminance), and Fourier transformation of the time sequential signals are performed, the length of the longest eyelash, the amount of the eyelashes, the thickness of the eyelashes and the number of the eyelashes are obtained, and two or more pieces of data are compared.COPYRIGHT: (C)2013,JPO&INPIT【課題】 マスカラ、睫毛用トリートメント、睫毛美容液、各種サプリメント、飲食物等による睫毛に対する育毛効果の有無や大小、睫毛の装飾性の向上効果等を客観的、経時的に評価できる方法及び装置の提供。【解決手段】 マブタを閉じた目元の白黒写真から解析する方の目元の画像を切出し、当該画像を明暗によるヒストグラムが横軸方向に最も暗い値から最も明るい値に分布して広がるように補正した補正画像に基づいて、最長の睫毛の長さの測定、2値化画像とヒストグラムの作製、睫毛上をラインスキャンして横軸を時間、縦軸を明暗(輝度)とする時系列信号の出力、当該時系列信号のフーリエ変換を行って、最長の睫毛の長さ、睫毛の量、睫毛の太さ、睫毛の本数を求め、また複数のデータ間の対比を行うことからなる睫毛の解析方法及びそのための解析装置。【選択図】 図1
