　以下、図面に基づいて本発明の実施の形態を説明する。 Embodiments of the present invention will be described below based on the drawings.
＜概要＞
・本発明では、顔を示す顔データを用いて顔の状態を評価することができる。「顔データ」とは、顔（例えば、顔の形状）を示すデータである。例えば、「顔データ」は、顔の画像、あるいは、顔を測定した値（例えば、３次元形状測定機が測定した値）である。本明細書では、「顔の画像」を用いて顔の状態を評価する実施形態を説明するが、本発明は、「顔の画像」だけでなく「顔を測定した値」を用いた顔の状態の評価にも適用することができる。

・例えば、顔の３次元形状を示す画像は、顔が撮影された１つまたは複数の画像（つまり、２次元の１つまたは複数の画像）から構築された３次元形状をもとに生成された画像（つまり、２次元の画像が加工された画像）である。また、例えば、顔の３次元形状を示す画像は、３次元形状測定機が測定した値をもとに生成された画像である。
・本開示の一実施形態では、複数の方向から顔が撮影された複数の２次元の画像から、顔の３次元形状を構築することができる。 <Overview>
- In the present invention, facial data representing a face can be used to evaluate the state of the face. “Face data” is data indicating a face (for example, the shape of the face). For example, "face data" is an image of a face or a value obtained by measuring the face (for example, a value measured by a three-dimensional shape measuring machine). Although the present specification describes an embodiment that evaluates the condition of a face using a "image of the face", the present invention provides a facial evaluation using not only the "image of the face" but also "measured values of the face". It can also be applied to condition assessment.
・For example, the image of the face is an image showing the three-dimensional shape of the face, an enlarged image taken by a skin measuring device used at a cosmetics store, etc., an image taken by a camera such as a digital camera, etc. .
・For example, an image showing the three-dimensional shape of a face is generated based on a three-dimensional shape constructed from one or more images of the face (that is, one or more two-dimensional images). This image is a processed image (that is, an image obtained by processing a two-dimensional image). Also, for example, an image showing the three-dimensional shape of a face is an image generated based on values measured by a three-dimensional shape measuring machine.
• In one embodiment of the present disclosure, a 3D shape of the face can be constructed from multiple 2D images of the face taken from multiple directions.

　しわ指標は、しわの状態を示す指標である。しわ指標は、顔の状態を示す複数の指標（具体的には、目尻のシワ、目の下のシワ、額のシワ、眉間のシワ）の評価結果をもとに評価される。 The wrinkle index is an index that indicates the state of wrinkles. The wrinkle index is evaluated based on evaluation results of a plurality of indices indicating the state of the face (specifically, wrinkles at the corners of the eyes, wrinkles under the eyes, wrinkles on the forehead, and wrinkles between the eyebrows).
　たるみ指標は、たるみの状態を示す指標である。たるみ指標は、顔の状態を示す複数の指標（具体的には、マリオネットライン、眼袋、鼻唇溝（ほうれい線））の評価結果をもとに評価される。 The slack index is an index that indicates the state of slack. The sagging index is evaluated based on evaluation results of a plurality of indices indicating facial conditions (specifically, marionette lines, eye bags, nasolabial folds (nasolabial folds)).
　図４は、本発明の一実施形態に係るしわ指標とたるみ指標の算出について説明するための図である。しわ指標とたるみ指標は、顔の状態を示す複数の指標の評価結果（図４の各項目（肌の悩み）のスコア）から算出される。以下、具体的に説明する。 FIG. 4 is a diagram for explaining calculation of a wrinkle index and a slackness index according to one embodiment of the present invention. The wrinkle index and the sagging index are calculated from evaluation results of a plurality of indices indicating the state of the face (scores for each item (skin troubles) in FIG. 4). A specific description will be given below.
　しわ指標は、「１．目尻のシワのスコア（Ｘ１）」と、「２．目の下のシワのスコア（Ｘ２）」と、「３．額のシワのスコア（Ｘ３）」と、「４．眉間のシワのスコア（Ｘ４）」と、から算出（しわ指標をｆ１とすると、ｆ１（Ｘ１，Ｘ２，Ｘ３，Ｘ４））される。なお、スコアは、各項目（肌の悩み）を数値化したものであり、顔の画像の画像処理により算出される。 The wrinkle index is "1. Eye corner wrinkle score (X1)", "2. Under eye wrinkle score (X2)", "3. Forehead wrinkle score (X3)", and "4. Glabella wrinkle score (X4)" (if the wrinkle index is f1, f1 (X1, X2, X3, X4)). The score is obtained by digitizing each item (skin trouble) and is calculated by image processing of the face image.
　たるみ指標は、「５．マリオネットラインのスコア（Ｘ５）」と、「６．眼袋のスコア（Ｘ６）」と、「８．鼻唇溝（ほうれい線）のスコア（Ｘ８）」と、から算出（たるみ指標をｆ２とすると、ｆ２（Ｘ５，Ｘ６，Ｘ８））される。なお、スコアは、各項目（肌の悩み）を数値化したものであり、顔の画像の画像処理により算出される。 The sagging index is obtained from "5. Marionette line score (X5)", "6. Eye bag score (X6)", and "8. Nasolabial fold (nasolabial fold) score (X8)". It is calculated (f2 (X5, X6, X8) where f2 is the slackness index). The score is obtained by digitizing each item (skin trouble) and is calculated by image processing of the face image.
　図２の説明に戻る。 Return to the description of Figure 2.
　総合指標評価部１０４は、第２指標評価部１０３が評価した複数の指標についての評価結果をもとに、総合指標について評価する。例えば、総合指標評価部１０４は、対象者２０が複数の類型のうちのいずれの類型に属するかを判断する。 The comprehensive index evaluation unit 104 evaluates the comprehensive index based on the evaluation results of the plurality of indexes evaluated by the second index evaluation unit 103. For example, the comprehensive index evaluation unit 104 determines which of the plurality of types the subject 20 belongs to.
＜＜総合指標＞＞
　ここで、総合指標について説明する。総合指標は、複数の指標（例えば、しわ指標とたるみ指標の２つ）に基づく総合的な指標である。例えば、総合指標は、しわ指標のレベルとたるみ指標のレベルをもとに分類された複数の類型である。図５および図６を参照しながら、総合指標について詳細に説明する。 <<Comprehensive Index>>
Here, the general index will be explained. A comprehensive index is a comprehensive index based on a plurality of indices (for example, a wrinkle index and a sagging index). For example, the general index is a plurality of types classified based on the level of the wrinkle index and the level of the sagging index. The general index will be described in detail with reference to FIGS. 5 and 6. FIG.
　図５は、本発明の一実施形態に係るしわ指標とたるみ指標から顔の状態を解析した結果を示す図である。１０代～５０代の被験者のしわ指標とたるみ指標を算出したところ、図５のような結果が得られた。図５では、図４の手法により算出されたしわ指標：ｆ１のスコア、および、図４の手法により算出されたたるみ指標：ｆ２のスコア、の各年齢の平均値を示す。図５に示されるように、しわ、たるみともに、年齢に比例して増加している。 FIG. 5 is a diagram showing the result of analyzing the state of the face from the wrinkle index and sagging index according to one embodiment of the present invention. When the wrinkle index and sagging index of subjects in their teens to fifties were calculated, the results shown in FIG. 5 were obtained. FIG. 5 shows average values for each age of the wrinkle index f1 score calculated by the method of FIG. 4 and the sagging index f2 score calculated by the method of FIG. As shown in FIG. 5, both wrinkles and sagging increased in proportion to age.
　図６は、本発明の一実施形態に係るしわ指標とたるみ指標から顔の状態を解析した結果を示す図である。 FIG. 6 is a diagram showing the results of facial condition analysis from wrinkle indexes and sagging indexes according to an embodiment of the present invention.
　図６に示されるように、しわ指標を４つのレベル（Level　１、Level　２、Level　３、Level　４）に分け、たるみ指標を４つのレベル（Level　１、Level　２、Level　３、Level　４）に分けて、被験者の顔の肌の状態を１６の類型（Ａａ、Ｂａ、Ｃａ、Ｄａ、Ａｂ、Ｂｂ、Ｃｂ、Ｄｂ、Ａｃ、Ｂｃ、Ｃｃ、Ｄｃ、Ａｄ、Ｂｄ、Ｃｄ、Ｄｄ）に分類することができた。 As shown in Fig. 6, the wrinkle index is divided into four levels (Level 1, Level 2, Level 3, Level 4), and the sagging index is divided into four levels (Level 1, Level 2, Level 3, Level 4). Separately, the condition of the facial skin of the subject is classified into 16 types (Aa, Ba, Ca, Da, Ab, Bb, Cb, Db, Ac, Bc, Cc, Dc, Ad, Bd, Cd, Dd). I was able to
　図６では、２０歳から４０歳の被験者の、図４の手法により算出されたしわ指標：ｆ１のスコアおよび図４の手法により算出されたたるみ指標：ｆ２のスコアの分布を示す。このように、同じ年代の被験者であっても、各々の被験者が、種々の類型に属することが分かる。 Fig. 6 shows the distribution of scores of wrinkle index f1 calculated by the method in Fig. 4 and slackness index f2 score calculated by the method of Fig. 4 for subjects aged 20 to 40. In this way, it can be seen that each subject belongs to various types even if the subjects are of the same age.
　図２の説明に戻る。総合指標評価部１０４は、対象者２０が複数の類型（例えば、図６で説明した１６の類型）のうちのいずれの類型に属するかを判断することができる。 Return to the description of Figure 2. The comprehensive index evaluation unit 104 can determine to which of a plurality of types (for example, 16 types described in FIG. 6) the subject 20 belongs.
