Description
本発明は、メイクアップ化粧料の使用者が最も自然な色であると感じる自然化粧肌色を予測し、さらに、その自然化粧肌色をつくる化粧料を容易に選択できるようにする方法に関する。 The present invention relates to a method for predicting a natural makeup skin color that a user of a makeup cosmetic feels to be the most natural color, and further enabling easy selection of a cosmetic that produces the natural makeup skin color.
一般に、ファンデーション、アイシャドウ、口紅等のメイクアップ化粧料を皮膚に適用した場合の色（即ち、化粧肌色）は、その化粧料塗膜の下地となっている皮膚の色の影響を大きく受けるので、化粧料自体が有する固有の色と化粧肌色とは異なる。 In general, the color when makeup cosmetics such as foundations, eye shadows, and lipsticks are applied to the skin (ie makeup skin color) is greatly affected by the color of the skin underlying the cosmetic coating film. The inherent color of the cosmetic itself is different from the makeup skin color.
そのため、メイクアップする者の意向に沿った化粧肌色をつくり出すメイクアップ化粧料を、メイクアップ化粧料自体が有する固有の色に基づいて選択することは難しい。メイクアップ化粧料の選択によっては、化粧肌色は、素肌色に対して極めて不自然な風合いのものとなる。 Therefore, it is difficult to select a makeup cosmetic that creates a makeup skin color in accordance with the intention of the person making up based on the unique color of the makeup cosmetic itself. Depending on the choice of makeup cosmetics, the makeup skin color may have a very unnatural texture with respect to the bare skin color.
そこで、メイクアップ化粧料を適用する被験者あるいは化粧アドバイザーにとっては、メイクアップ化粧料の選択時に、当該被験者の化粧意向に沿い、かつ自然な風合いの仕上がりを呈するメイクアップ化粧料を如何に選択するかが課題となっている。 Therefore, for a subject or a makeup advisor who applies makeup cosmetics, how to select makeup cosmetics that conform to the subject's intention to make and have a natural texture finish when selecting makeup cosmetics. Has become an issue.
これまで、メイクアップ化粧料を皮膚に適用した場合の化粧肌色に関して、化粧肌色を客観的に予測する方法はいくつか提案されている（特許文献１）。しかしながら、メイクアップ化粧料の被験者の意向を満たし、かつ自然な風合いの仕上がりに感じられる化粧肌色を客観的に予測する方法や、そのような化粧肌色を作り出すメイクアップ化粧料を容易に選択できる方法はない。
そこで、本発明は、メイクアップ化粧料の被験者の意向を満たし、かつ自然な風合いの仕上がりに感じられる化粧肌色を客観的に予測し、そのような化粧肌色を作り出すメイクアップ化粧料を容易に選択できるようにすることを課題とする。 Therefore, the present invention objectively predicts a makeup skin color that satisfies the intention of the subject of makeup cosmetics and feels a natural texture finish, and easily selects a makeup cosmetic that creates such makeup skin color. The challenge is to make it possible.
本発明は、上記の課題を解決すべく、複数の被験者について、メイクアップ化粧料適用前の色を測色すると共に、被験者の自然化粧肌色（即ち、被験者のメイクアップ化粧料適用前の色に対する修正意向を満たし、かつ最も自然な色であると感じる化粧肌色）を測色し、メイクアップ化粧料適用前の測色値と自然化粧肌色の測色値の回帰直線を求め、一方、任意の被験者の自然化粧肌色を、その被験者のメイクアップ化粧料適用前の測色値と前記回帰直線とに基づいて予測することを特徴とする自然化粧肌色の予測方法を提供し、この方法により被験者の自然化粧肌色を予測し、一方、被験者が別途複数のメイクアップ化粧料を適用した後の化粧肌色を予測し、これら化粧肌色の予測値と自然化粧肌色の予測値との色空間上の距離が最も小さくなるメイクアップ化粧料を自然感を最大にするメイクアップ化粧料として選択する化粧料の選択方法を提供する。 In order to solve the above problems, the present invention measures the color before applying makeup cosmetics for a plurality of subjects, and also applies the natural makeup skin color of the subjects (that is, the color before applying makeup cosmetics of the subjects). The color of the skin color that satisfies the correction intention and feels the most natural color) is measured, and a regression line between the colorimetric value before applying the makeup cosmetic and the colorimetric value of the natural cosmetic skin color is obtained. A natural makeup skin color prediction method is provided, which predicts a natural makeup skin color of a subject based on a colorimetric value of the subject before applying makeup cosmetics and the regression line. The natural makeup skin color is predicted, while the subject predicts the makeup skin color after applying a plurality of makeup cosmetics separately, and the distance in the color space between the predicted value of the makeup skin color and the predicted value of the natural makeup skin color is Smallest The natural sense of the makeup cosmetics made to provide a cosmetic composition of the selection method to be selected as makeup cosmetics to maximum.

本発明の自然化粧肌色の予測方法によれば、予め、複数の被験者のメイクアップ化粧料適用前の測色値と、各被験者についての自然化粧肌色の測色値との回帰直線を求めておく。この回帰直線は、前記複数の被験者が共通に有する肌色修正意向を反映していると考えられる。したがって、この回帰直線を用いて任意の被験者の自然化粧肌色を予測する本発明によれば、任意の被験者が、自己の化粧意向が満たされ、かつ自然な風合いの仕上がりであると感じる化粧肌色（自然化粧肌色）を客観的に予測することが可能となり、また、自然化粧肌色をつくりだすメイクアップ化粧料を容易に選択することが可能となる。 According to the natural cosmetic skin color prediction method of the present invention, a regression line between a colorimetric value of a plurality of subjects before applying makeup cosmetics and a natural cosmetic skin color of each subject is obtained in advance. . This regression line is considered to reflect the skin color correction intention shared by the plurality of subjects. Therefore, according to the present invention for predicting the natural makeup skin color of any subject using this regression line, the makeup skin color that any subject feels that his / her makeup intention is satisfied and has a natural texture finish ( Natural makeup skin color) can be objectively predicted, and makeup cosmetics that produce natural makeup skin color can be easily selected.
また、本発明の化粧料の選択方法によれば、任意の被験者の化粧肌色の予測値と自然化粧肌色の予測値との色空間上の距離が最も小さくなるようにメイクアップ化粧料を選択するので、各被験者の化粧意向が満たされ、かつ、化粧の仕上がりの自然感を最大にするメイクアップ化粧料を簡便に客観的に選択することが可能となる。 Further, according to the cosmetic selection method of the present invention, the makeup cosmetic is selected so that the distance in the color space between the predicted value of the makeup skin color and the predicted value of the natural makeup skin color of any subject is minimized. Therefore, it is possible to simply and objectively select a makeup cosmetic that satisfies the makeup intention of each subject and maximizes the natural feeling of the makeup finish.
以下、本発明の自然化粧肌色の予測方法、化粧料の選択方法及び化粧料の選択装置について詳細に説明する。 The natural cosmetic skin color prediction method, cosmetic selection method and cosmetic selection device of the present invention will be described in detail below.
本発明の自然化粧肌色の予測方法は、任意の被験者にメイクアップ化粧料を適用した場合に当該被験者の化粧意向に沿い、かつ当該被験者が最も自然であると感じる化粧肌色を予測する方法である。 The natural cosmetic skin color prediction method of the present invention is a method for predicting a cosmetic skin color that is in line with the subject's intention to apply and that the subject feels most natural when applying makeup cosmetics to any subject. .
ここで、化粧肌色を予測するメイクアップ化粧料の種類としては、ファンデーション、口紅、アイシャドウ、頬紅等をあげることができる。 Here, examples of makeup cosmetics for predicting makeup skin color include foundations, lipsticks, eye shadows, blushers, and the like.
この自然化粧肌色の予測方法においては、まず、複数の被験者について、メイクアップ化粧料適用前の色を測色すると共に、各被験者に複数種のメイクアップ化粧料をそれぞれ適用した場合に、各被験者の自己の化粧前の色に対する修正意向を満たし、かつ各被験者が最も自然な色であると感じる自然化粧肌色を測色し、これらメイクアップ化粧料適用前の測色値と自然化粧肌色の測色値との回帰直線を求める。この回帰直線は、前記複数の被験者が共通に有する、化粧前の色に対する修正意向を反映していると考えられる。 In this natural makeup skin color prediction method, first, for a plurality of subjects, the color before applying makeup cosmetics is measured, and each subject is applied with a plurality of types of makeup cosmetics. Measure the natural makeup skin color that satisfies each person's intention to correct the color before makeup and that each subject feels the most natural color, and measure the colorimetric value and natural makeup skin color before applying these makeup cosmetics. Find a regression line with color values. This regression line is considered to reflect the intention to correct the color before makeup that the plurality of subjects have in common.
例えば、１７〜２９歳の種々の素肌色を有する女性７６名を被験者とし、各被験者の素肌色と、各被験者に種々のファンデーションを塗布した場合の化粧肌色のうち、各被験者が自然化粧肌色として選択した化粧肌色を測色し、これら素肌色と自然化粧肌色との分布を図示すると図２のようになる。図２から、被験者の素肌色の分布の中心色の方向に自然化粧肌色の分布が集まっていることがわかる。したがって、これらの被験者には、化粧肌色をその集団の素肌色の分布の中心に合わせたいという修正意向がはたらいており、その意向を基礎として各被験者が最も自然であると感じられる化粧肌色が選択されていることがわかる。 For example, 76 females having various skin colors of 17 to 29 years old are subjects, and each subject has a natural makeup skin color among the skin color of each subject and the makeup skin color when various foundations are applied to each subject. The color of the selected makeup skin color is measured, and the distribution of these bare skin color and natural makeup skin color is shown in FIG. It can be seen from FIG. 2 that natural makeup skin color distributions are gathered in the direction of the center color of the subject's skin color distribution. Therefore, these subjects have a correction intention to match the makeup skin color to the center of the group's bare skin color distribution, and the makeup skin color that each subject feels most natural is selected based on that intention. You can see that
そこで、本発明においては、メイクアップ化粧料適用前の測色値と自然化粧肌色の測色値の回帰直線を求めた後、任意の被験者にこの回帰直線を適用し、当該被験者の自然化粧肌色を予測する。 Therefore, in the present invention, after obtaining a regression line between the colorimetric value before applying the makeup cosmetic and the colorimetric value of the natural makeup skin color, the regression line is applied to any subject, and the natural makeup skin color of the subject is examined. Predict.
より具体的には、例えば図２の場合の被験者のファンデーション塗布前の素肌色に対する自然化粧肌色の色差を求め、この色差を素肌色に対してプロットすると図１に示すように回帰直線が得られる。この回帰直線は次式で表される。 More specifically, for example, when the color difference of the natural makeup skin color with respect to the skin color before applying the foundation of the subject in the case of FIG. 2 is obtained and this color difference is plotted against the skin color, a regression line is obtained as shown in FIG. . This regression line is expressed by the following equation.
そこで、予め、上述の回帰直線を求めておき、次に、自然化粧肌色を予測しようとする任意の被験者について素肌色Ｈ0を測色し、その素肌色の測色値を回帰直線にあてはめて化粧後の色差についてのｄＨを求める。そして、当該被験者の自然化粧肌色Ｈpを次式 Therefore, the above-described regression line is obtained in advance, and then the skin color H 0 is measured for any subject who is to predict natural makeup skin color, and the colorimetric value of the skin color is applied to the regression line. Determine dH for color difference after makeup. And the natural makeup skin color H p of the subject is
このように任意の被験者について自然化粧肌色を予測するにあたり、各被験者の化粧に対する修正意向は、当該被験者の年代、嗜好等によって異なる傾向があるので、好ましくは、当該被験者と共通の修正意向を有していると考えられる母集団について予め上述の回帰直線を求めておき、その回帰直線を利用する。 Thus, in predicting natural makeup skin color for any subject, each subject's intention to modify makeup tends to vary depending on the subject's age, preference, etc., and therefore preferably has a common intention to modify the subject. The above-described regression line is obtained in advance for the population considered to be, and the regression line is used.
また、この自然化粧肌色の予測に必要とされる、メイクアップ化粧料適用前の測色と自然化粧肌色の測色とは、任意の表色系を用いておいて行うことができる。例えば、マンセル表色系の色相Ｈ、明度Ｖ、彩度Ｃ、及びＬ*ａ*ｂ*表色系の明度指数Ｌ*、知覚色度指数ａ*、ｂ*、Ｌ*ｕ*ｖ*表色系の明度指数Ｌ*、知覚色度指数ｕ*、ｖ*、及びＸＹＺ表色系の基礎刺激値Ｘ、Ｙ、Ｚから選ばれる少なくとも一つにより測色値を求めればよい。 Further, the color measurement before applying the makeup cosmetic and the color measurement of the natural makeup skin color, which are required for the prediction of the natural makeup skin color, can be performed using any color system. For example, the hue H, lightness V, saturation C, and L * a * b * color system lightness index L * , perceptual color index a * , b * , L * u * v * table of the Munsell color system The colorimetric value may be obtained from at least one selected from the lightness index L * of the color system, the perceptual chromaticity index u * , v * , and the basic stimulus values X, Y, Z of the XYZ color system.
本発明の化粧料の選択方法は、上述のようにして予測される自然化粧肌色を作り出すメイクアップ化粧料を客観的に予測する方法である。この方法においては、当該被験者に種々のメイクアップ化粧料を適用した場合の化粧肌色を予測する。そして、その化粧肌色の予測値と前述の自然化粧肌色の予測値との色空間上の距離が最も小さくなるメイクアップ化粧料を自然感を最大にするメイクアップ化粧料として選択する。 The method for selecting a cosmetic according to the present invention is a method for objectively predicting a makeup cosmetic that produces the natural makeup skin color predicted as described above. In this method, the makeup skin color when various makeup cosmetics are applied to the subject is predicted. Then, the makeup cosmetic that minimizes the distance in the color space between the predicted value of the makeup skin color and the predicted value of the natural makeup skin color is selected as the makeup cosmetic that maximizes the natural feeling.
例えば、図３に示すように、当該被験者の素肌色の色相と明度が（Ｈ0，Ｖ0）であり、当該被験者の自然化粧肌色の予測値としての色相と明度が（Ｈp，Ｖp）であるとする。また、５色のファンデーションＡ〜Ｅから当該被験者に対して自然感を最大にするメイクアップ化粧料を選択する場合に、まず、これらの一つのファンデーションＡを当該被験者に塗布したときの化粧肌色（Ｈx(A)，Ｖx(A)）を予測する。なお、この化粧肌色（Ｈx(A)，Ｖx(A)）は、公知の発色理論により予測することができ、図示したように、ファンデーションＡの固有の塗布色（Ｈ1(A)，Ｖ1(A)）と、当該被験者の素肌色（Ｈ0，Ｖ0）との中間の色を呈することとなる。次に、このファンデーションＡを当該被験者に塗布した場合の化粧肌色の予測値（Ｈx(A)，Ｖx(A)）と、自然化粧肌色の予測値（Ｈp，Ｖp）との色空間上の距離を求める。同様にして、他のファンデーションＢ〜Ｅについても、そのファンデーションを当該被験者に塗布した場合の化粧肌色の予測値と自然化粧肌色の予測値（Ｈp，Ｖp）との色空間上の距離を求める。そしてこれらファンデーションＡ〜Ｅのうち、色空間上の距離が最小となるものを、自然感を最大にするメイクアップ化粧料として選択する。 For example, as shown in FIG. 3, the hue and lightness of the subject's bare skin color are (H 0 , V 0 ), and the hue and lightness as predicted values of the natural makeup skin color of the subject are (H p , V p). ). In addition, when selecting a makeup cosmetic that maximizes the natural feeling for the subject from the five color foundations A to E, first, a makeup skin color when one of these foundations A is applied to the subject ( Hx (A) , Vx (A) ) are predicted. Incidentally, the decorative skin color (H x (A), V x (A)) can be predicted by a known color theory, as shown, specific coating color foundation A (H 1 (A), V 1 (A) ) and an intermediate color between the subject's bare skin color (H 0 , V 0 ). Next, the color of the predicted value (H x (A) , V x (A) ) of the makeup skin color and the predicted value (H p , V p ) of the natural makeup skin color when this foundation A is applied to the subject. Find the distance in space. Similarly, for the other foundations B to E, the distance in the color space between the predicted value of the makeup skin color and the predicted value of the natural makeup skin color (H p , V p ) when the foundation is applied to the subject. Ask. Of these foundations A to E, the one having the smallest distance in the color space is selected as a makeup cosmetic that maximizes the natural feeling.
ここで、被験者に種々の色のメイクアップ化粧料を適用した場合の化粧肌色の予測方法としては、特に制限はないが、予測操作の簡便性の点から、特開平９−１７８５６０号公報に記載されている方法にしたがうことが好ましい。即ち、予め、色の異なる複数の被塗布体について、メイクアップ化粧料適用前の色と適用後の色とをそれぞれ測色し、メイクアップ化粧料適用前の測色値と適用後の測色値との回帰直線を求める。一方、メイクアップ化粧料の選択対象である被験者について、メイクアップ化粧料の適用前の色を測色する。そして、被験者のメイクアップ化粧料適用前の測色値と、前記被塗布体について求めた、メイクアップ化粧適用前の測色値と適用布後の測色値との回帰直線とに基づいて、被験者がメイクアップ化粧料を適用した後の化粧肌色を予測する。 Here, the method for predicting the makeup skin color when applying various types of makeup cosmetics to the subject is not particularly limited, but is described in JP-A-9-178560 from the viewpoint of simplicity of the prediction operation. It is preferable to follow the methods that are used. That is, for a plurality of coated objects having different colors, the color before applying the makeup cosmetic and the color after the application are respectively measured, and the colorimetric value before applying the makeup cosmetic and the color measurement after applying the cosmetic. Find the regression line with the value. On the other hand, the color before application of the makeup cosmetic is measured for a subject who is a selection target of the makeup cosmetic. And based on the colorimetric value before applying the makeup cosmetics of the subject and the regression line of the colorimetric value before applying the makeup makeup and the colorimetric value after applying the cloth obtained for the coated body, The subject predicts the makeup color after applying the makeup cosmetic.
なお、この化粧肌色の予測において、メイクアップ化粧適用前の測色値と適用後の測色値との回帰直線を求めるために使用する被塗布体としては、特に制限はなく、被験者である必要はない。人の皮膚の他、経時的に色が安定している人工皮革、レプリカ、紙など種々の素材のものを使用することができる。好ましくは当該メイクアップ化粧料が適用される皮膚と同様の柔軟性や表面凹凸形状を有しているものを使用する。これにより、実際に皮膚に化粧料を適用した場合と同様の化粧料の付着状態や展延性を得ることができる。 In addition, in this prediction of makeup skin color, there is no particular limitation on the coated body used for obtaining a regression line between the colorimetric value before applying makeup makeup and the colorimetric value after application, and it is necessary to be a subject. There is no. In addition to human skin, various materials such as artificial leather, replica, and paper whose color is stable over time can be used. Preferably, those having the same flexibility and surface unevenness as the skin to which the makeup cosmetic is applied are used. Thereby, the adhesion state and spreadability of cosmetics similar to the case where cosmetics are actually applied to the skin can be obtained.
また、色空間上の距離を求めるにあたり、その表色系には特に制限はなく、マンセル表色系、Ｌ*ａ*ｂ*表色系、Ｌ*ｕ*ｖ*表色系及びＸＹＺ表色系から選ばれる少なくとも一つとすることができる。 In obtaining the distance in the color space, the color system is not particularly limited, and the Munsell color system, L * a * b * color system, L * u * v * color system and XYZ color system are used. It can be at least one selected from the system.

Then, for each of the five types of foundations A to E, for each subject, a distance (color difference) on the color space between the makeup skin color and the predicted value of the natural makeup skin color is obtained, and the distance on the color space is 5 types. The smallest of the foundations A to E was selected as the optimum foundation. Table 1 shows the types of foundations thus selected and the skin color of each subject. Moreover, each subject's evaluation with respect to the foundation selected in this way was represented in the following four steps.
A: Very satisfied B: Satisfactory Δ: Neither can be said ×: Unsatisfactory This result is shown in Table 1.
