Non-Patent Documents

1 and 2, in order to change the appearance of the hair and change the impression of the person, it is proposed to partially dye the hair (makeup) based on the subjectivity of the hairdresser (coordinator). .
However, the content of makeup proposals made by coordinators largely depends on individual subjectivity, and it is difficult to say that the content of proposals to customers has universality. In addition, through our research, we learned that the location and thickness of the make-up area are not the only factors that change people's impressions. Furthermore, there is a demand that the customer wants to grasp what kind of impression is given by the current hair, for example.
Under these circumstances, there is a need for customers to grasp their own impressions, and for coordinators to be able to give advice on hair colors for partial make-up areas (hair color change areas) in order to meet the customer's wishes.
The present invention has been made in view of the above problems, and relates to a technique for extracting one of an impression about a person's appearance including hair and partial makeup information by designating the other.

According to the method provided by the present invention, the impression type information that determines to which impression classification the impression regarding the appearance of a person's face including hair falls, and the partial makeup regarding the hair color of the hair are provided. By specifying one of the impression type information and the partial makeup information using the correlation information indicating the statistically obtained correlation between the partial makeup information and the partial makeup information, the other can be extracted. Partial makeup information can be objectively extracted from the type information or the impression type information.

Examples of preferred embodiments of the present invention will be described below with reference to the drawings. The drawings of the present embodiment are all for explaining the technical idea, configuration and operation of the present invention, and do not specifically limit the configuration. Moreover, in all the drawings, the same constituent elements are denoted by the same reference numerals, and overlapping descriptions are omitted as appropriate.

<Overview>
An outline of a method for extracting hair color-related information in this embodiment will be described.
FIG. 1 shows impression type information for determining to which impression category an impression regarding the appearance of a person's face including hair falls, and partial makeup information regarding partial makeup for the color of the hair. or impression type information that determines which impression classification the impression regarding the appearance of a person's face including hair falls under, and a portion related to partial make-up regarding the hair color of the hair 1 shows an overview of the card method, which is an experimental method for calculating correlation information indicating the correlation between makeup information and total hair color information about the hair color of the entire hair region.
Here, although the details will be described later, the impression type information is information for determining which impression classification the impression regarding the appearance of a person's face including hair corresponds to, and is specific information indicating the impression classification. (Details will be described later, but for example, "feminine", "cute", "gorgeous", and "mode" correspond). Similarly, the "impression item" corresponds to an impression classification (e.g., corresponding to "feminine", "cute", "gorgeous", and "mode") that is specific information indicating an impression. In this embodiment, the "impression type information" may also be referred to as "impression item". The partial make-up information is information about the partial make-up of the hair color of the hair. quantity). Similarly, the "partial makeup item" is also information about partial makeup for the hair color of the hair. amount of hair), etc. In this embodiment, "partial makeup information" may also be described as "partial makeup item". Further, the whole head hair color information is information related to the hair color of the whole head area. Corresponding to color. Similarly, the "whole head item" is also information about the hair color of the whole head area. hair color etc. In this embodiment, the "whole head hair color information" may also be described as "whole head item".

As shown in FIG. 1, a plurality of types of image cards are prepared by combining predetermined partial make-up items and predetermined full-head items. Although the image card is illustrated in FIG. 1, it is actually an image card created based on an image of the same model.
Here, among the partial make-up items, five hair colors (hereinafter sometimes referred to as partial make-up colors) for partial make-up are navy black, mode blue, olive khaki, pearl rose, and shine gold. Prepare 15 patterns of image cards (hereinafter also referred to as stimulus images) from combinations of 3 items of cool pink, royal brown, and forest khaki as the hair color of all heads in the head item, and prepare 8 types of inserting each. . That is, a total of 120 sheets are prepared. The eight types of application are as shown in Fig. 2, for a straight hairstyle, partial makeup color is applied 1) thinly from the top of the head to the tip of the hair, 2) thickly applied from the top of the head to the tip of the hair, 3) in the middle of the hair. 4) Put in from the vicinity to the ends of the hair, 4) Put in the ends of the hair, and for hairstyle curls, apply partial makeup color 1) thinly from the top of the head to the ends of the hair, 2) thicken from the top of the hair to the ends of the hair 3) apply from the middle of the hair to the tip of the hair; 4) apply to the tip of the hair;
Then, the subject was shown the image cards (15 patterns) of the same insertion method, and the subject was asked, "How much of the predetermined impression (for example, feminine) do you feel?" Arrange the image cards. For example, the subject was asked, "How 'feminine' do you feel?" Place the felt card on the left end of the scale, and place all the image cards on the scale. A score is added according to the position of the scale where the image card is placed. From the results of all subjects, impression items related to facial appearance including hair, partial make-up items related to partial make-up of hair color, and whole-head items related to hair color of the entire head area. Correlation information indicating the statistically obtained correlation is calculated.
In the present embodiment, the correlation information indicating the correlation is calculated from the numerical values obtained by the card method shown in FIG. 1, but the present invention is not limited to this. The experiment method does not matter. In addition, since the number of subjects does not matter, for example, one specific subject (a subject who is highly conscious of hair color and impression of how people look, such as a hair artist or stylist) can use the card method shown in FIG. Correlation information that indicates a correlation calculated based on the results of an experiment may be used. By using such correlation information, regardless of what kind of person uses the method of extracting hair color-related information according to the present embodiment, the impression type information can be obtained from the partial makeup information, or the partial makeup can be obtained from the impression type information. Information can be objectively extracted with similar results.
Correlation information indicating the correlation among impression items, partial makeup items, and overall head items is calculated through such experiments. Although the details will be described later, by changing the conditions (for example, the conditions of the partial makeup items) when creating the image card, it is possible, for example, to determine what kind of correlation between the partial makeup items and the impression items. It is possible to calculate whether there is information.

The ``impression type information for determining which impression classification the impression regarding the appearance of a person's face including hair belongs to'' is the atmosphere received by the observer from the overall appearance of the appearance of the person's face including the hair. , is determined (judged) by the subjective criteria of the observer. Here, the number of observers does not matter whether they are one or more. When there is only one observer, the user (the user of the hair-color-related information extraction method or the hair-color-related information extraction device) can use the hair color and the hair color, such as a hair artist or a stylist, to serve as an objective determination index. It is preferable that the observer is a person (a charismatic person) who is highly conscious of the impression of how people look, and the impression type information determined by such a observer based on subjective criteria may also be used. Moreover, when there are multiple observers, it is preferable to use an integrated result (statistically obtained correlation, which will be described later) of determination (judgment) based on each observer's subjective criteria.
Impression type information (impression items) used in this embodiment will be described with reference to FIG.
Fig. 3 shows a Styling Map (registered A four-quadrant impression map classified into four tastes defined as a trademark) is shown. Impression 4-Quadrant Map is divided into 4 tastes, "Aqua Taste", "Bright Taste", "Earth Taste", and "Crystal Taste", which are analyzed and classified by 3 axes divided into left, right, up and down, and diagonally. being classified. The tastes are classified into four tastes: the first axis having the warm zone and the cool zone as opposite poles, the second axis having the soft zone and the hard zone as opposite poles, and the third axis showing the difference in vividness. In this embodiment, one image word included in each taste is extracted as an impression item.

Styling image words included in bright taste include, for example, cute, pretty, pop, girly, casual, boyish, active, and sporty. These styling image words are arranged on different maps depending on the degree of warm impression and the degree of soft impression. That is, the degree of warm impression and the degree of soft impression differ depending on the styling image word. In the present embodiment, "cute" is used as an impression item having an image of a cute flower with a bright orange color or roundness.
"Earth taste" is classified as warm if it is cool or warm, and hard if it is soft or hard. It has a gentle gradation, and is an image of a deep brown and the leaves of a large tree rooted in the earth. Styling image words included in earth taste include, for example, impression words such as gorgeous, wild, antique, ethnic, sexy, folklore, classic, and natural. These impression words are arranged on different maps depending on the degree of warm impression and the degree of hard impression. That is, the degree of warm impression and the degree of hard impression differ depending on the styling image word. In this embodiment, "gorgeous" is used as an impression item having an image of a deep brown color or a leaf of a large tree rooted in the ground.
"Crystal taste" is classified as cool if it is cool or warm, and hard if it is soft or hard. Styling image words included in Crystal Taste include, for example, impression words of mode, dandy, hard, mannish, sharp, punk, formal, and rock. These impression words are arranged on different maps depending on the degree of cool impression and the degree of hard impression. That is, the degree of cool impression and the degree of hard impression differ depending on the styling image word. In this embodiment, "mode" is used as an impression item having an image of a clear jewel emitting a sharp dark blue color or a cold light.
Note that in the present embodiment, by presenting the subject in advance with clothing representing the impression of "feminine", "cute", "gorgeous", and "mode", the impression of each subject with respect to each impression type information (each impression item) can be determined. to unify.

"Head hair" refers to hair that grows on the head of a person, and is hair. Fibers and the like are also included in hair. In the case of hair other than the hair that grows on the human head, hair similar to that used for wigs and those that function as substitutes for head hair are preferable.
"Partial make-up information on partial make-up for hair color of hair" refers to information (item ). Hair color refers to the hair color of the part related to partial make-up, the area of the part related to partial make-up, the position of the part related to partial make-up (e.g. root, tip, etc.), partial make-up Color difference (ΔE) between the close-up part and the whole head, hue difference (ΔH) between the partial make-up part and the whole head, saturation difference (ΔS) between the partial make-up part and the whole head, etc. are mentioned. The "color" of "hair color" is a measured color measured using a colorimeter or software for extracting color codes.
Partial hair colors related to partial make-up include color names, coordinates of a predetermined color space, and the like. The area of the part related to partial makeup includes the size of the part related to partial makeup, the ratio of the part related to partial makeup to the whole head, and the like. The position of the part related to partial makeup is the name indicating the position, such as the root, the tip, and from the root to the tip of the hair, the length from the root of the part related to partial makeup, and the entirety of the part related to partial makeup. hair length ratio, etc.

The “whole head region of hair” is the region of all the hair, including the part partially made up.
"Full hair color information about the hair color of the entire head area" is information (items) related to the hair color of the entire head area. information (item) about the hair color of the entire head area including the part that has been ). In addition, the "color" of "hair color" is a measured color measured using a colorimeter, software for extracting color codes, or the like.

“Correlation information indicating correlation” is correlation information calculated based on the results of a predetermined experiment performed on one or more subjects, although the details will be described later. "Correlation information" may be in any form of information such as graphs, tables, maps, formulas, numerical values, etc. calculated based on the results of predetermined experiments. It may be based on the results of performing a given experiment multiple times on one subject. When calculating correlation information that indicates a correlation based on multiple results of a predetermined experiment, the correlation information that indicates the statistically obtained correlation is calculated by performing predetermined statistical processing on the multiple results. becomes. The correlation function is preferably a statistically obtained correlation, and more preferably a correlation based on the results of a plurality of subjects.
When the correlation information indicating the correlation between the impression item and the partial makeup item is used, if the impression item is specified, the partial makeup item highly correlated with the impression item is extracted, and if the partial makeup item is specified, the partial makeup item is correlated with the partial makeup item. It becomes possible to extract the impression items with high . Further, when the correlation information indicating the correlation with the impression item, the partial makeup item, and the overall head item is used, if the impression item is specified, the partial makeup item and the overall head item that are highly correlated with the impression item are extracted. If makeup items are specified, impression items and full-head items that are highly correlated with partial makeup items can be extracted, and if full-head items are specified, impression items and partial makeup items that are highly correlated with full-head items can be extracted. Become.

<1) Correlation information between overall head items, partial makeup items (color difference (ΔE), placement method (area ratio)), and impression items>
The partial make-up item includes area information regarding the area of the part where the hair is partially made up and the color difference (ΔE) between the hair color of the entire head region and the hair color of the part where the make-up is partially made up.
The "area for partially applying make-up of hair" is the area of the portion on which hair is partially applied.
"Area information about the area" is a value determined by the thickness and length of the part where the hair is partially made up. It includes the ratio of the length to the total length of the hair.
"Area information is information on areas with different make-up areas" includes information on a plurality of areas with different areas of parts to be partially made up, for example, information on areas to be partially made up. This includes different areas (numerical values), different area ratios with parts of the same head that are partially made up, and different length ratios.
The “color difference (ΔE)” in the present embodiment means the hair color of the entire head area and the hair color of the part where makeup is applied (hereinafter sometimes referred to as partial makeup color) in the L ^* a ^* b ^* color space. It is also the distance (difference) between the coordinates of the hair color of the whole head area and the partial makeup color. The color difference (ΔE) also varies depending on the method of application. In the experiment of 1), the hair color of the entire head area of the same hue (for example, royal brown) and the partial makeup color of the same hue (for example, pearl rosé) were used, and the hair color of the entire head area and the partial makeup color were different. In order to examine the influence of the color difference (ΔE) on impression items, the color difference (ΔE) is set according to the application method of the partial makeup color. In the experiment 1), a difference in color difference (ΔE) was provided by applying dark/thin partial makeup colors of the same hue. Since a difference and a hue difference also occur, the color difference (ΔE) in this embodiment includes a saturation difference, a lightness difference, and a hue difference.
The details of the experiment 1) are shown with reference to FIGS. 4 to 7. FIG.

Subjects: 5 females in their twenties Impression items: Feminine, Cute, Gorgeous, and Mode Stimulation images: Combinations of stimulation images shown in Fig. 4 (total of 48 images)
For the combination of stimulus images, the experiment shown in Fig. 1 was performed in advance, and from the stimulus images that exceeded a predetermined standard for each impression item, the combination of hair color, partial makeup color, and application method for the entire head area was extracted. Then, the experiment 1) was performed on the extracted combinations. Note that FIG. 4 shows a representative combination of each impression item among combinations of stimulus images that exceed a predetermined standard. Experiment 1) may be performed for all of the hair color of the entire head area, partial makeup color, and application method shown in FIG. It is preferable to determine the combination to be used for the stimulus image using the tendencies for each impression item extracted in .

FIG. 5 shows how to put in the hairstyle/partially made-up part used in the experiment 1).
As shown in FIG. 5, hair style curls C1 to C3 have partial make-up colors applied from the roots to the ends, and C4 to C6 have partial make-up colors applied to the ends. And C2 and C5 show the case where partial makeup color is put in standard (general use area regardless of impression), C2 and C5 are standard (100%), and 75% area ratio C1 and C4 are obtained when partial makeup colors are added, and C3 and C6 are obtained when partial makeup colors are added in an area ratio of 125% to C2 and C5. Similarly, straight hairstyles S1 to S3 apply partial make-up color from the roots to the ends of the hair, and S4 to S6 apply partial make-up color to the ends of the hair. And S2 and S5 show the case where partial makeup color is put in standard (general use area regardless of impression), S2 and S5 are standard (100%), and 75% area ratio S1 and S4 are cases where partial makeup color is added, and S3 and S6 are cases where partial makeup color is added for an area ratio of 125% to S2 and S5. In addition, the numbers indicating the percentages described in each image indicate the ratio of the partially made-up part when the whole head area is 100, and are area information.

FIG. 6 shows a conceptual diagram showing the relationship between the difference in the area of the partially made-up portion and the color difference (ΔE) in the experiment of 1).
The horizontal axis represents the color difference (ΔE) between the hair color of the entire head area and the partially made-up portion, and the color difference (ΔE) from the hair color of the entire head area increases toward the right. The first and second from the left, and the second and third from the left have the same color difference (ΔE) step width, but the third and fourth from the left have twice the former color difference (ΔE) step size. is.
The vertical axis represents the difference in the area of the part to be partially made up, and the middle row is the standard area when partially made up regardless of the impression item. The area of the partially made-up portion in the upper stage is 75% of the area in the middle stage, and the area in the lower stage is 125% of the area in the middle stage.
(1) to (4), (1a) to (4a), and (1b) to (4b) described in FIG. 6 indicate coordinates by the horizontal axis and the vertical axis, which are the coordinates of each stimulus image.

FIG. 7 is an example of stimulus images used in the impression item: Feminine experiment. This is the same as the relationship between the difference in area of the partially made-up portion and the color difference (ΔE) shown in FIG.
(1) to (4) show the case where the hairstyle is straight and partial make-up is put on the ends of the hair in a standard area. The color difference value increases from (1) to (4). The color difference between (1) and (2), and between (2) and (3) has the same step width. there is
(1a) to (4a) are stimulation images in which partial make-up colors are applied to an area corresponding to 125% of the partial make-up area of (1) to (4). That is, the stimulation image has a larger area for partial make-up than (1) to (4). Similar to (1) to (4), the color difference value increases from (1a) to (4a).
(1b) to (4b) are stimulation images in which partial make-up colors are applied to an area corresponding to 75% of the partial make-up area of (1) to (4). That is, the stimulation image has a smaller area for partial make-up than (1) to (4). Similar to (1) to (4), the color difference value increases from (1b) to (4b).
Therefore, when the 12 stimulus images shown in FIG. 7 are compared, the easily recognizable stimulus image that makes it easy to see that partial makeup is applied has a large area and color difference (4a). In addition, the stimulus image in which partial make-up is difficult to recognize at a glance is small in both area and color difference (1b). Regarding the experimental results of 1), as described below, it is important to present the partial makeup application as an extraction result because the degree to which the impression item is perceived as a predetermined impression item differs depending on the partial application of makeup. is. In order to obtain appropriate experimental results, it is important to prepare stimulus images with different partial make-up areas and color differences. It should be noted that when presenting the extraction result, not only the numerical information but also the corresponding stimulus image may be presented.
FIG. 8(a) to FIG. 8(d) show the correlation information of the results of the experiment 1) performed by the card method shown in FIG. 1 using such stimulus images. 8(a) to 8(d) have the same relationship as (1) to (4), (1a) to (4a), (1b) to (4b) shown in FIG. are the coordinates of the stimulus image of . Although not shown in FIGS. 8(a) to 8(d), in the following description, each coordinate is represented by (1) to (4), (1a) to (4a), (1b) to (4b). sometimes refers to

FIG. 8(a) shows impression items: color difference (ΔE) and area ratio suitable for feminine. In the case of feminine, high correlation information was obtained for the combination of full head item: royal brown, partial makeup item: hair color pearl rosé, and hairstyle with straight hair ends. ), and three types with different areas of partially made-up portions. The horizontal axis and vertical axis in FIG. 8(a) are as described in FIG. In addition, many subjects felt that the stimulus image corresponding to the coordinates filled in with the darkest color in FIG. was less. A majority of the subjects (3 subjects) felt that even the stimulus image corresponding to the coordinates filled in with the lightest color was feminine.
As is clear from FIG. 8A, many subjects felt that the stimulus image ((1b) stimulus image) with the smallest partial makeup area and the smallest color difference was feminine. Specifically, in the case of partial make-up with an area of about 13 to 17% of the entire head area and a thickness of about 8 to 12 mm (ΔE = 5.7 to 7.8). , Many subjects felt feminine.

FIG. 8(b) shows the impression item: color difference (ΔE) and area ratio matching cute. In the case of cute, high correlation information was obtained when the combination of all head items: cool pink, partial makeup items: shine gold for hair color, and curled hair ends for hairstyle, so four different color differences ( .DELTA.E), three types with different areas of partially made-up portions were tested. The horizontal axis and vertical axis in FIG. 8(b) are as described in FIG. In addition, many subjects felt that the stimulus image corresponding to the coordinates filled in with the darkest color in FIG. was less. A majority of the subjects (3 subjects) felt that even the stimulus image corresponding to the coordinates filled in with the lightest color was cute.
As is clear from FIG. 8(b), many subjects felt that the stimulus image (the stimulus image of (1)) with the standard partial makeup area and the smallest color difference was cute. Specifically, when partial make-up is applied with an area of about 17 to 23% of the entire head area and a thickness of about 8 to 12 mm (ΔE = 6.6 to 10.0). , Many subjects felt cute.

FIG. 8(c) shows impression items: color difference (ΔE) and area ratio matching gorgeously. In the case of Gorgeous, high correlation information was obtained when all hair items: royal brown, partial makeup items: olive khaki for hair color, and curls for hairstyles. ), and three types with different areas of partially made-up portions. The horizontal axis and vertical axis in FIG. 8(c) are as explained in FIG. In addition, many subjects felt that the stimulus image corresponding to the coordinates filled in with the darkest color in FIG. was less. A majority of the subjects (3 subjects) felt that even the stimulus image corresponding to the coordinates filled in with the lightest color was gorgeous.
As is clear from FIG. 8(c), many subjects felt that the stimulus image (the stimulus image of (1a)) with a large partial makeup area and the smallest color difference was gorgeous. Specifically, when partial make-up is applied with an area of about 26 to 34% of the entire head area and a thickness of about 12 to 18 mm (ΔE = 9.1 to 11.2). , Many subjects felt gorgeous.

FIG. 8(d) shows impression items: color difference (ΔE) and area ratio matching the mode. In the case of mode, high correlation information was obtained when the entire head item was forest khaki, the partial makeup item was mode blue for hair color, and the hair style was straight. ), and three types with different areas of partially made-up portions. The horizontal axis and vertical axis in FIG. 8(d) are as described in FIG. In addition, many subjects felt that the stimulus image corresponding to the coordinates filled in with the darkest color in FIG. was less. A majority of the subjects (3 subjects) felt that even the stimulus image corresponding to the coordinates filled in with the lightest color was a mode.

It becomes possible. Also, in a beauty parlor or the like, a coordinator can propose an appropriate partial make-up color to meet the customer's wishes.

<Usage example 2>
A partial make-up item is specified, and in the case of the specified partial make-up item, an impression item given to a person is extracted.
For example, since the user is using or has used the partial make-up color of "shine gold", the predetermined input device is used to specify "shine gold" as the partial item. The hair color-related information extraction device 50 extracts an impression item (for example, cute) that has a high correlation with Shine Goal based on the stored correlation information, and displays the extraction result on the display unit 56 . Also, when the user designates the hair color of the entire head region together with the partial makeup color, impression items highly correlated with both items are extracted, and the extraction result is displayed on the display unit 56 .
In this way, the user can grasp what kind of impression his/her hair color with partial make-up color of his/her preference gives to others, and can utilize it for selecting clothes etc. according to impression items. Also, at a beauty parlor or the like, it is possible for a coordinator to give appropriate advice on what kind of impression the customer will have when the hair is colored.

<Usage example 3>
The impression item, partial makeup color, and hair color of the entire head area are designated, and the partial makeup item is extracted as to how the partial makeup color should be applied.
For example, if the user wants to have a "cute" impression by using "cool pink" as the hair color for the entire head area and "shine gold" as the partial makeup color, "cool pink", "shine gold", and "cute" are used. ” is specified using a predetermined input device. The hair color-related information extraction device 50 extracts how to apply the partial makeup color of Shine Gold (area, density) based on the stored correlation information. The hair color-related information extraction device 50 not only sets the area for the partial makeup color as a numerical value, but also displays a specific simulation image on the display unit 56, and a specific application method such as a recommended application method. It is preferable to display
By doing so, the user can understand how to apply the Shine Gold partial makeup color to create a cute impression, and the partial makeup color can be effectively used.

<Usage example 4>
Designate the impression item and the hair color of the whole head area, and extract the partial makeup item (hair color range).
For example, if the user currently has cool pink hair on the entire head area and wants to apply partial makeup to give a “cute” impression, the user selects “cool pink” and “cute” as predetermined. Specify using an input device. In usage example 4, the correlation information in FIG. 12 is used to extract partial makeup items. Therefore, instead of extracting a specific color as in Usage Example 1, a hue range of partial makeup colors that are highly correlated with "cool pink" and "cute" is extracted. The hair color of the whole head area is cool pink, and as a partial makeup color that gives a "cute" impression, a hair color that has a similar hue color scheme or an adjacent hue color scheme to the hair color of the whole head area is extracted.
By doing so, even when giving advice on partial makeup colors from among many color variations such as in a beauty salon, it is possible to appropriately give advice on the desired impression of the customer.

The correlation information stored in the above-described hair color-related information extraction device 50 may be stored in the storage unit 51 only with correlation information having a high correlation, for example, correlation information with a score equal to or higher than a predetermined standard. Regardless, all the calculated correlation information may be stored. In the former case, when extracting full-head items or partial makeup items that match impression items desired by the user, or if extracting impression items that match full-head items or partial makeup items, results based on low correlation information are extracted. Therefore, there is no need to store correlation information that is unlikely to be used.

If there is no item with a high correlation with the specified item, or if there is no item with a score equal to or higher than a predetermined standard, the above-described hair color-related information extraction device 50 extracts "corresponding item" as the extraction result. None” may be extracted. By doing so, even if the user freely specifies items, it is possible to extract appropriate results.

Extraction result selection processing may be provided to select whether to extract one. By doing so, it becomes possible to extract the information required by the user depending on the situation.

<Modification>
In this embodiment, the "impression item" in this embodiment is based on the impression four-quadrant map with three axes shown in FIG. 3, but is not limited to this. For example, a first axis having a warm zone with a warm impression, a cool impression and a cool zone shown in FIG. Impressions (image words) arranged on a coordinate plane with axes may be used as impression items.

In this embodiment, four items of "feminine", "cute", "gorgeous", and "mode" are used as impression items, but the items are not limited to these. For example, other image words classified into the four-quadrant map shown in FIG. 3 may be used. Further, the specific image word may not be an impression item, but may be an item indicating one quadrant of the four-quadrant map shown in FIG. 3, such as "impression item with cool and soft impression". By doing so, it is possible to make impression items with a broader concept.

The correlation information shown in FIG. 12 also has the following relationships.
In the case of impression items with a cool impression and a soft impression, the hair color of the entire head area and the hair color of the partial make-up are selected so that they have a middle difference color scheme, an adjacent color scheme, or a similar color scheme. Make-up items and all-head items are extracted, and in the case of impression items with a warm impression and a soft impression, the hair color of the whole head area and the hair color of the partial make-up are similar hue color schemes or adjacent hue color schemes. In the case of impression items with a cool impression and a hard impression, the hair color of the entire head area and the hair color of the partial makeup are complementary colors. , middle difference color scheme, or contrast color scheme, partial makeup items and full head items are extracted, and in the case of impression items with a warm and hard impression, Partial make-up items and full head items are extracted so that the hair color of make-up and the hair color of the make-up have a middle difference color scheme or an adjacent color scheme.
Further, in addition to extracting the hue considering the color scheme of the hair color of the whole head area and the hair color of the partial make-up, the color difference (ΔE) and the area shown in FIG. 8 may also be extracted together.

The correlation information shown in FIG. 12 also has the following relationships.
A high correlation was not obtained for any of the impression items for partial makeup colors having the same hue as the hue of the hair color of the entire head area. Therefore, when specifying the full head item and the partial makeup item, it may be possible to prevent the combination of the same hue from being specified in advance.

The correlation information shown in FIG. 8 also has the following relationships.
1) A combination of area and color difference (combination A) extracted by designating the impression item of cool impression and soft impression has a small area and a small color difference, and 2) a warm impression. The combination of area and color difference (combination B) extracted by designating impression items with a soft and soft impression is larger than the area of combination A and about the same as the color difference of combination A; 3) warm impression; and the combination of area and color difference (combination C) extracted by designating the hard impression impression item is larger than the area of combination B and about the same as the color difference of combination A and combination B; 4) cool impression; and a combination of area and color difference (combination D) extracted by designating a hard impression item has an area similar to that of combination B and a color difference greater than those of combinations A, B and C. The partial make-up area and the color difference extracted when the cool impression and soft impression impression item are specified are the smallest area and the smallest for the whole head area among the four impression items. Since it is a color difference, it is the combination closest to the whole head area. Therefore, when partial make-up is applied, it is the most inconspicuous and modest method among the four impression items. In addition, the partial make-up area and the color difference extracted when the impression item with a warm and hard impression and the impression item with a cool and hard impression, including a hard impression, are specified, What is different from the whole head area, that is, how to apply makeup that makes it easy to recognize that makeup is applied when partial makeup is applied is extracted. In this way, depending on the impression item, the combination of the highly correlated partial makeup area and color difference differs.

The correlation information shown in FIG. 14 also has the following relationships.
In the case of an impression item with a cool impression and a soft impression, in the case of an impression item with a warm impression and a soft impression, in the case of an impression item with a cool impression and a hard impression, and with a warm impression. In the case of an impression item with a strong and hard impression, when the hues of the hair color of the whole head area and the hair color of the partial make-up are assimilated, a value with a small saturation difference is extracted and a cool value is extracted. In the case of impression items with both a hard impression and warm impression with a hard impression, the hues of the hair color of the entire head area and the hair color of the partial make-up are colored. When the intensity contrast is performed, a value with a large chroma difference is extracted. Here, "the hue of the hair color of the whole head area and the hair color of the partial make-up are assimilated" means that the subject feels that the hair color of the whole head area approaches the color of the partial make-up. relationship. "The hue of the hair color of the whole head area and the hair color of the partial make-up contrasts with the saturation" means that the hair color of the whole head area is brighter than the case where the partial make-up color is not applied. Or, it is a relationship that the subject felt that it was dull.
In addition, when the hue of the hair color of the whole head area and the hair color of the partial make-up are assimilated, the impression item gives a cool and soft impression, and the impression item gives a warm and warm impression. When the saturation difference is smaller in the case of the impression item with a soft impression than in the case of the impression item with a cool impression and a hard impression and the case of the impression item with a warm impression and a hard impression. Therefore, in the case of impression items with a cool and soft impression and in the case of impression items with a warm and soft impression, a value with a small saturation difference is recommended. Extraction is preferred.
Further, in addition to extracting the saturation difference between the hair color of the entire head area and the partial make-up, the color difference (ΔE) and the area shown in FIG. 8 may also be extracted.

In this embodiment, in Usage Example 4, when using the correlation information shown in FIG. 12, the hair color of the entire head area is specified as a predetermined hair color as an all-head item, but it is not limited to this. For example, by specifying the hue of the hair color of the entire head area and the impression item, the hue range of the partial makeup color that has the correlation shown in FIG. 12 is extracted for the specified hue of the hair color of the entire head area. You may make it By doing so, it is possible to deal with various hair colors of the entire head region.

The above-described hair color-related information extraction device 50 stores, in the storage unit 51, impression type information that determines to which impression category the impression regarding the appearance of a person's face, including the hair, corresponds to, and information about the hair color of the hair. Although the correlation information indicating the correlation between the partial makeup information related to typical makeup and the correlation information is stored, the present invention is not limited to this.
For example, the storage unit 51 stores impression type information that determines which impression category an impression regarding the appearance of a person's face including hair falls under, and partial makeup information regarding partial makeup for the color of the hair. and total hair color information about the hair color of the entire head region of the hair. The user uses the designation unit 52 to designate one of impression type information, partial makeup information, and total hair color information. The extractor 53 extracts the remaining two combinations. As an extraction result, the remaining two combinations are output to, for example, a display device. A selection unit (selection unit (not shown)) that allows the user to select any combination from the remaining two combinations that are output may be provided. The selection unit corresponds to an input device such as a keyboard (including a touch keyboard) and a pointing device provided in the mobile terminal 50 . Using such a hair color-related information extraction device 50, the following processing can be performed.
In this embodiment, in Usage Example 1, specifying one of the impression type information, partial makeup information, or full hair color information (specifying the impression item "feminine") allows the remaining two A combination (for example, partial makeup color "Pearl Rose" and hair color "royal brown" for the entire head area) is extracted, and as partial makeup information, in addition to partial makeup color, how to put partial makeup color (for example, The area to be put in lightly/intensely, etc.) is also extracted, and the extraction result is displayed on the display unit 56 as an output means. In addition to this, a selection means may be provided that allows the user to select which combination to select from among the combinations based on the displayed content. For example, a check box is displayed for the combination of the extraction result displayed on the display unit 56, and the combination desired to be selected can be checked by the selection unit. Based on the checked combination, the extraction device 50 for hair color-related information can display an image in which the extracted color is applied on the display unit 56 so that the user can imagine the application.

In this embodiment, the extraction result is displayed on the display unit 56, which is output means, but the present invention is not limited to this. For example, the extraction result may be output to a paper medium, and the output means in this case corresponds to a paper medium and a printer that prints on the paper medium.

In this embodiment, the item to be extracted is one item with a high correlation, but it is not limited to this. If a plurality of items above a predetermined reference point are extracted, a plurality of items may be extracted. In this case, the scores may be extracted together. For example, when specifying an impression item and a head item (specifying two items) and extracting a partial makeup item (extracting one item), the partial makeup item to be extracted has a predetermined reference point or more. If multiple items are extracted, the score ranking (including information indicating the strength of correlation) may be extracted together.

In this embodiment, the L ^* a ^* b ^* color space and the HSV color space are used for the description of the hair color of the entire head region and the hair color of the partial make-up, but the present invention is not limited to this. Other color spaces (eg, Munsell color system) may be used.

In this embodiment, the partial makeup color is assumed to be a single color, but this is not a limitation, and multiple colors may be used. In addition, the materials of the hair in the whole head area and the area to which the partial makeup color is applied may be different. For example, the entire head area may be hair, and the area to which the partial makeup color is applied may be similar to head hair.

In this embodiment, the case where the entire head area of the head has hair has been described, but the present invention is not limited to this. For example, the case of partial wigs as shown in FIGS. 17(a), 17(b), and 17(c) will be described.
FIG. 17(a) is a diagram showing a wig for bangs, for example, a wig used in combination with a hat. Partially apply makeup. The bangs part wig is configured like a headband, and may be separate from the cap, or may be attached to the cap.
FIG. 17(b) is a diagram showing a hair tip wig, which is used in combination with a hat, for example. The tip-part wig shown in FIG. 17(b) is used as the entire head area, and part of the tip-part wig is partially made up. The tip portion wig and the hat may be separate bodies, or may be attached to the hat.
FIG. 17(c) is a diagram showing a tip-part wig used for a hairstyle such as a ponytail, which is used by being attached to a hairstyle formed by tying the hair. The hairstyle formed by tying the hair and the wig at the tip shown in FIG. 17(c) are used as the whole head region, and the wig at the tip shown in FIG. 17(c) is partially made up. Note that, as shown in FIGS. 17(a) to 17(c), a part of the head may be attached with something other than hair, such as a hat or a hair ornament.

Also, the partial wigs of FIGS. 17(a) to 17(c) may be used in the following combinations. When partial wigs are combined, the color of each partial wig before partial makeup is the same color or a similar color.
1) The wig for bangs shown in Fig. 17(a) and the wig for hair ends shown in Fig. 17(b) are used in combination (used simultaneously). In this case, the bangs partial wig of FIG. 17(a) and the hair tip portion wig of FIG. Partial make-up is applied to part of the wig for the tip of b), or part of the wig for the bangs of FIG. 17(a) and part of the wig for the tip of FIG. 17(b) is partially applied.
2) The wig for bangs shown in FIG. 17(a) and the wig for hair ends shown in FIG. 17(c) are used in combination (used at the same time). In this case, the hairstyle formed by tying the bangs part wig of FIG. 17(a) and the hair of FIG. 17(c) is partly made up, or part of the bangs part wig of FIG. 17(a) and part of the tip part wig of FIG. 17(c) are partially made up. .
3) The wig for the tip portion of FIG. 17(b) and the wig for the tip portion of FIG. 17(b) are used in combination (used simultaneously). In this case, the tip portion wig of FIG. 17(b) and the tip portion wig of FIG. Make a part of the wig or all the wigs with partial makeup.

Further, the partial makeup may be performed as follows for the partial wig of the combination described above.
a) The partial makeup color shall be a single color within the wig.
b) Partial makeup colors shall be multiple colors in the wig.
Table 1 shows the combinations of the partial wigs 1) to 3) and the partial makeup colors a) and b) of the above combinations.

For example, in the case of (1) in Table 1, the partial makeup color is a pattern in which a single color is applied to the bangs partial wig shown in FIG. A partial makeup color is applied to the bangs partial wig shown in a) in multiple colors, and a partial makeup color is applied in a single color to the hair tip partial wig shown in FIG. It shows a pattern of cases.
In any of the combinations shown in Table 1, using the correlation information indicating the correlation between the impression item, the partial makeup item, and the whole head item according to this method, by specifying a part of the item, the specified item and can extract different items.
Even in the case of partial wigs, the same effect as described above can be obtained.

<Wig set>
A wig set consisting of the above partial wig and a hair coloring agent for applying (dying) the partial wig will be described.
A wig set is composed of correlation information indicating the correlation between partial wigs, hair coloring agents, and the aforementioned impression items, partial makeup items, and overall head items. The hair coloring agent included in the wig set is the color of the partial wig included in the wig set and/or the hair that can be recognized when the partial wig is worn on the head. Only hair color agents highly correlated with predetermined impression items, or a plurality of hair color agents. When a plurality of hair coloring agents are included, based on the correlation information included in the wig set, the user can apply the hair coloring agent that is highly correlated with the desired impression item. The correlation information includes information indicating at least one of the hair coloring agent highly correlated with the impression item desired by the user, information indicating the strength of the correlation (information indicating the relationship between the strength of the correlation and the hair coloring agent), and how to apply the hair coloring agent. include at least one of the following information (time, area, etc.). The relationship between the strength of the correlation and the hair color agent is, for example, if the impression item is feminine and the hair color of the entire head area is royal brown, the hair color agent with the highest correlation strength is A, and the next correlation is A. The hair color agent with the highest strength is B, the impression item is gorgeous, and the hair color of the entire head area is royal brown. The hair coloring agent is information that associates the strength of correlation with the hair coloring agent contained in the wig set, such as A. In addition, provision by recording (printing) the correlation information on a paper medium, provision by recording the correlation information on an electronic medium, provision by using a two-dimensional code (by reading the two-dimensional code, the user can obtain the correlation information) The provision method does not matter, such as access to a browsable website). Specifically, an instruction manual included in the package together with the hair coloring agent, or a printed material on the surface of the package containing the hair coloring agent can be exemplified. By doing so, the user can wear a wig that gives the impression that the user wants to give, and can change the impression that the user wants to give even with the same partial wig just by changing the partial makeup color, so that the user can wear the partial wig. More fun to use.

<Hair color agent set>
The hair color agent set includes impression type information that determines to which impression category an impression regarding the appearance of a person's face including hair falls, and partial makeup information regarding partial makeup for the color of the hair. and a hair coloring agent for applying a hair color based on the correlation information. As described above, the correlation information is provided by means of a paper medium, an electronic medium, a two-dimensional code, or the like. Moreover, the hair coloring agent may be of either a single color or multiple colors.
A hair coloring agent set of such correlation information and hair coloring agents enables the user to apply hair color that gives the desired impression based on the correlation information.

<How to edit the head image>
The head image editing method is a head image editing method that makes it possible to give a predetermined impression using correlation information with the above-described impression type information, partial makeup information, and overall hair color information.
"impression type information for determining which impression classification the impression regarding the appearance of a person's face including hair falls under", "partial makeup information regarding partial makeup for hair color", "hair The "whole hair color information about the hair color of the whole head region" and the "correlation information indicating the correlation" are as described above.
The "person's head image including hair" includes not only a person's head image captured for impression evaluation, but also a person's head image processed with image editing software. It also includes a character image (so-called avatar image) created based on a person's (user's) head image and a character (illustration) created by imitating a person.
"Head image" means any of the so-called frontal image including a human face, the so-called rear-facing image (hair only) that does not include a human face, and the so-called profile image that includes a part of a human face. It's okay. The “acquisition step of acquiring a face image of a person including hair” is a step of acquiring a head image, and acquisition methods such as acquisition using a line and acquisition from a predetermined medium do not matter.
The ``calculating step of analyzing the head image obtained by the obtaining step and calculating partial makeup information and full hair color information'' includes image analysis of the obtained head image, partial makeup hair color, and full head area. This is a step of calculating the hair color of The entire head area or the hair color of the entire head area is specified for the head image, and the entire head area and partial makeup-related parts are extracted based on the specified contents. When the entire head area is specified, the hair color of the specified portion is calculated using, for example, software for extracting color codes, and the entire head area and partial make-up are extracted from the calculation result. When the hair color of the whole head area is specified, the part of the hair color is extracted as the whole head area, and the other part is extracted as the part related to partial make-up. For the part extracted as the part related to partial makeup, for example, software for extracting a color code is used to calculate the hair color of the part extracted as the part related to partial makeup. Note that the acquired head image may be an image without partial makeup. In addition, the method of calculating the hair color of the entire head area and the hair color of the part related to partial makeup can be calculated by comparing with pre-prepared teaching data, in addition to the software for extracting the color code described above. does not matter.
The 'designating step of designating impression type information' is a step of designating the desired impression.
The "extracting step" extracts highly correlated partial makeup information and total hair color information based on the correlation information and the specified impression type information. The contents of the extraction are the same as those described in the above-mentioned "method for extracting information related to hair color".
The "selecting step" selects at least one of the partial makeup information and the total hair color information extracted in the extracting step.
"Hair color change process" is a process of adding color to the acquired head image using image editing software based on the selection result (selected partial makeup information and/or full hair color information) in the selection process. .
By doing so, it is possible to create an image with a desired impression. Since an image acquired by photographing or the like can be edited into an image or illustration that gives a desired impression, for example, it is possible to edit a photograph that gives a desired impression, such as a commemorative photograph or a promotional photograph. In addition, it is possible to edit the impression you want to give to a specific person, such as an online meeting or promotional video. In addition, it is possible to create a photograph or moving image that gives a desired impression without changing the actual hair color. In addition, even in the case of a character image created by imitating a person, an illustration of a character, or an animation image using a character, the correlation with impression type information, partial makeup information, and all hair color information is Since it has the same tendency as , it is possible to edit (create) with the impression you want to give these character images. Therefore, for example, it is possible to provide a game or movie character with an added impression.
In the "calculation step of analyzing the head image obtained by the obtaining step and calculating partial makeup information and total hair color information", the hair color of the entire head area and the hair color of the partial makeup is calculated, it is also possible to calculate only the whole head area (the part where the hair is present) without calculating the hair color. By adding color to the calculated whole head region using image editing software based on the selection result of the selection process, it is possible to create an impression image. On the other hand, in the ``calculation step of performing image analysis on the head image obtained in the obtaining step, and calculating partial makeup information and total hair color information,'' By calculating , it is also possible to evaluate the impression of the head image acquired in the acquisition step.
