Description

  The present invention relates to a dyeing material selection system and a selection method for dyeing hair as desired, and a computer program used in the system.

When hair dyeing is performed in a beauty salon or barber shop (hereinafter collectively referred to as “hair salon”), in order to provide customers with a variety of hair colors, a salon clerk mixes a plurality of dye materials and mixes the desired colors. And dyeing may be performed with the prepared mixed material. However, even relatively veteran salon clerk do not know so many color combinations (recipes) that can produce a desired color mixture.
For this reason, when dyeing using a mixed material is proposed to a customer, it may be a one-pattern proposal, and it is difficult to make proposals according to various preferences.

Therefore, the present applicant has already proposed a simulation system that can appropriately display a hair color after dyeing even when dyeing materials are mixed (see Patent Document 1).
According to this simulation system, the storage unit stores the correction coefficient of the coordinate value of the color space when different types of staining materials are mixed, and the control unit stores the coordinate data and correction coefficient of the input type of staining material. Since the estimated coordinate value of the dyed material after mixing is obtained based on the mixing ratio, the hair color after dyeing can be appropriately displayed even when the dyeing material is mixed.

JP2013-84081A

The conventional simulation system is a system that estimates the hair color after dyeing when using a mixed material. Therefore, the customer's desired color (finished color after finishing) is used as input information, and the type and mixing of the dyeing material is reversed. The ratio and the coating amount could not be calculated.
For this reason, even if a conventional simulation system is used, it is not possible to immediately obtain the type or mixing ratio of the dyeing material that realizes the desired color, and the user can quickly and easily respond to the customer's request. There was a problem that it was difficult.

  The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a dyeing material selection system and the like that can promptly present a user with a dyeing material that realizes a desired color.

  (1) The selection system of the present invention is a system for selecting a dyeing material necessary for dyeing hair, and a predetermined mixture of a non-mixing material that is a single dyeing material and a plurality of the dyeing materials. Each coordinate data of the color space when dyed with a mixed material mixed at a ratio is recorded for each under color type, an input unit for inputting the under color type and desired color of the person to be dyed, The unmixed material or the mixed material whose coordinate value matches or approximates the inputted desired color is searched from the coordinate data corresponding to the input under color type, and the search result is output. A control unit, wherein the control unit executes the search for the unmixed material with a first priority.

According to the selection system of the present invention, the control unit searches the coordinate data corresponding to the input under color type for a non-mixed material or mixed material whose coordinate value matches or approximates the input desired color. Since the search result is output, an unmixed material or a mixed material that realizes a desired color is automatically obtained.
For this reason, the dyeing material which implement | achieves a desired color can be rapidly shown to a user, and a user can respond now to a customer's request quickly and easily.

Further, according to the selection system of the present invention, since the control unit searches for the non-mixed material with the first priority, the possibility that the non-mixed material realizing the desired color is output preferentially increases. .
For this reason, compared with the case where a mixed material is output preferentially, the adjustment work of a dyeing material can be performed more simply and rapidly, and a customer's satisfaction can be improved.

(2) In the selection system of the present invention, it is preferable that the control unit executes a search for the mixed material having a uniform mixing ratio with a second priority.
In this way, when a non-mixed material is not searched, there is an increased possibility that a mixed material having an equal mixing ratio is output. For this reason, compared with the case where the mixed material with an uneven mixing ratio is obtained preferentially, the adjustment work of the dyeing material can be performed more simply and quickly, and the customer satisfaction can be improved.

(3) In the selection system of the present invention, it is preferable that the control unit executes a search for the mixed material having a non-uniform mixing ratio with a third priority.
In this way, even when a non-mixed material or a mixed material with an equal mixing ratio is not searched, a mixed material with an uneven mixing ratio is output. For this reason, the mixed material which implement | achieves a desired color can always be shown to a user.

(4) In the selection system of the present invention, the input unit can further input the hair amount of the person to be dyed and the length of the application site, and the control unit can input the input hair amount and the application. It is preferable to calculate the application amount of the non-mixed material or the mixed material after the search based on the region.
In this case, since the control unit calculates the application amount of the staining material based on the input hair amount and the application site, the application amount of the staining material can be accurately calculated without waste.

(5) In the selection system of the present invention, the control unit further includes a display unit that displays a face image of a hair color corresponding to the input desired color and an operation unit for adjusting the desired color. The face image of the hair color corresponding to the desired color after adjustment is preferably displayed on the display unit.
In this case, since the control unit displays the hair color face image corresponding to the desired color after adjustment on the display unit, the user can select the desired color while confirming the result after dyeing.

(6) The selection method of the present invention is an invention that captures the above-described processing performed by the selection system of the present invention as a method invention. Therefore, the selection method of the present invention has the same effects as the selection system of the present invention.
(7) The computer program of the present invention is a computer program for causing a computer to execute the above-described processing performed by the selection system of the present invention. Therefore, the computer program of the present invention has the same operational effects as the selection system of the present invention.

  According to the present invention, it is possible to promptly present a user with a dye material that realizes a desired color, so that the user can quickly and easily respond to a customer's request. In addition, since the non-mixed material that realizes the desired color is output preferentially, the dyeing material adjustment operation can be performed more easily and quickly, and customer satisfaction can be improved.

[Image file database]
FIG. 3 is a structural diagram of the database DB1 of the image file F.
As shown in FIG. 3, the database DB <b> 1 has a large number of images created by applying different hair colors to the hair parts of the same face image (in this embodiment, the “model” face image shown in FIG. 11B). The file F has a data structure in which a large number of image files F are arranged three-dimensionally for each coordinate value (hereinafter referred to as “HSV value”) of the hair color HSV space.

The hue H of the HSV space is divided into a numerical value range of 0 to 360 for each predetermined value (for example, 1.0), and the saturation S and lightness B have a numerical value range of 0 to 100 (for example, 1.. 0). The database DB1 stores an image file F of face images of the same model photographed with a predetermined hairstyle for each HSV value divided as described above.
In the present embodiment, face images of a plurality of hairstyles can be selected. Therefore, the database DB1 shown in FIG. 3 exists for each selectable hairstyle model.

[Database of dyeing materials]
FIG. 4 is a structural diagram of the dyeing material database DB2 (in the case of fashion dyeing).
As shown in FIG. 4, the dye material database DB2 has a data structure in which the types of dye materials that can be used by hair salon users are arranged in the row direction, and the base color (under color) of the hair is arranged in the column direction. . In this embodiment, the “lightness level” of the hair before dyeing is employed as the under color of the hair.

The numerical value contained in one data box where the row and the column intersect is the RGB color space of the hair color after dyeing when the hair of the lightness level specified in the column is dyed with the dyeing material specified in the row. Coordinate data (hereinafter referred to as “RGB data”).
In the database DB2 shown in FIG. 4, the numerical values of the RGB data in the data box corresponding to the mixed color data string Ri (i = 1, 2,... N) are omitted to simplify the illustration.

“LV” in FIG. 4 means the lightness level of the hair before dyeing. In the database DB2 of the present embodiment, the hair before dyeing is dyed for each of the five lightness levels of “14 LV”, “12 LV”, “10 LV”, “8 LV”, and “4 LV” in each row. RGB data of hair color when dyed using a material is recorded.
“Yak (white background)” shown in FIG. 4 is RGB data when a predetermined dyeing material or mixed material specified in each row is applied to a white background object.

The lightness level is an index that describes the lightness of the hair in 15 levels so that the lightness increases as the value increases. Here, the average black hair of the Japanese is represented by “4LV”, and the state that has been brightened to the maximum by a decoloring action or the like is represented by “15LV”.
The database DB2 includes “single color data string R0” from the 1st to 24th lines and “mixed color data string Ri” (i = 1, 2,... N) from the 25th line.

The single color data row R0 includes RGB data of dyeing materials that can be used by the user (in this embodiment, 24 types of product names a1 to a24). That is, the single color data row R0 is RGB data when dyed with a single dye material (non-mixed material) a1 to a24.
The single color data row R0 is created by actually dyeing hair of each lightness level using each of the dyeing materials a1 to a24 and converting the RGB measurement values of the hair color after dyeing in this case into data. Yes.

The mixed color data row Ri includes RGB data of a mixed material in which any two colors of the dye materials a1 to a24 usable by the user are created at a predetermined mixing ratio. That is, the mixed color data row Ri is RGB data when the staining materials a1 to a24 are used in a two-liquid mixture.
For example, the mixed color data row R1 includes RGB data of 26 kinds of mixed materials when the mixing ratio of the dyeing material a1 and the dyeing material a2 is changed in increments of 1% from 50:50 to 75:25. .

In the mixed color data row R2, RGB data of 26 kinds of mixed materials when the mixing ratio of the staining material a1 and the staining material a3 that can be used by the user is changed in increments of 1% from 50:50 to 75:25. Is included.
In the mixed color data row R3, RGB data of 26 types of mixed materials when the mixing ratio is changed in increments of 1% from 50:50 to 75:25 for the staining materials a1 and a4 that can be used by the user. Is included.

Similarly, in the i-th mixed color data row Ri, 26 when the mixing ratio is changed in increments of 1% from 50:50 to 75:25 for the staining material aj and the staining material ak that can be used by the user. Contains RGB data for different types of mixed materials.
The total number n of the mixed color data row Ri is a case where any two staining materials aj and ak (j = 1 to 24, k = 1 to 24, j ≠ k) are selected from 24 types of staining materials a1 to a24. The number of combinations.

Therefore, the total number n of mixed color data string Ri _becomes n = ₂₄ C 2 = 276. Since one mixed color data string Ri includes 26 types of mixing ratios, all the mixed color data strings R1 to Rn include 276 × 26 = 7201 rows of RGB data.
Also for the mixed color data row Ri, the hair color at each lightness level is actually dyed using the mixed material obtained by mixing the two dyeing materials at the mixing ratio defined in each row, and in this case, the RGB measurement of the hair color is performed. It can be created by converting the value into data.

However, as described above, the total number n of the mixed color data row Ri is very large as 7201, and when these are actually dyed on the hairs having 5 lightness levels, 7201 × 5 = 36005 times of dyeing and RGB values Measurement is required.
Therefore, in the present embodiment, the RGB data value corresponding to the mixed color data string Ri is calculated using the simulator described in Japanese Patent Application Laid-Open No. 2013-84081 already filed by the present applicant, and the calculated value is used for each mixing value. It is described in the data box of the color data string Ri.

That is, the simulator can estimate the RGB value of the hair color after dyeing according to the lightness level of the hair before dyeing and the mixing ratio in the case of two-liquid mixing.
For this reason, if the RGB data corresponding to the mixed color data string Ri is calculated by the simulator, it is not necessary to actually repeat a large number of staining operations in accordance with the change in the mixing ratio, and the database DB2 is constructed more easily. be able to.

FIG. 4 illustrates the database DB2 in the case of “fashion dyeing”. However, the staining material database DB2 stored in the storage unit 25 includes a database (not shown) in the case of “white hair dyeing”.
The database of dyeing materials for gray hair dye is divided into three levels (10%, 30%, 50%) for each existing ratio of the amount of white hair with an undercolor lightness of 10 LV. In this respect, although different from the case of “fashion dyeing” in which the lightness level is divided into five stages, variations in the dyeing materials a1 to a24 and the mixing ratio are the same as in the case of “fashion dyeing”.

[Application amount calculation table]
FIG. 5 is an explanatory diagram of the application amount calculation table CT.
As shown in FIG. 5, the application amount calculation table CT has a table format in which the hair dyeing ranges of hair to be dyed are arranged in the row direction, and the types of hair amounts for fashion dyeing and white hair dyeing are arranged in the column direction. .

The hair dyeing range in the row direction is divided up to 60 cm in the order of 5 cm. The “new part (within 1.5 cm)” on the first line is the part of hair that has newly grown after the previous dyeing. The amount of hair in the row direction is divided into three ranges of “low”, “normal”, and “high”.
The determination of the hair dyeing range and the hair amount is performed by the amount of eyes by a user such as a salon clerk of the hair salon observing the hair of the person to be dyed.

The numerical values included in the calculation table CT of FIG. 5 indicate the application amount (unit is grams) required for non-mixed materials. Therefore, in the case of the mixed material, the amount of gram distributed according to the mixing ratio is the coating amount of each dyeing material constituting the mixed material.
For example, the application amount when dyeing a new part with a small amount of hair by fashion dyeing is 40 grams. In this case, in the case of using a two-component mixed medicine with a mixing ratio of 50%, 20 grams each is the application amount of each medicine.

[Execution procedure of drug selection process]
FIG. 6 is an explanatory diagram showing an execution procedure of a medicine selection process by the control unit 21 of the server computer 2.
In FIG. 6, the non-mixed material or the mixed material selected by the medicine selection process of the control unit 21 and the mixing ratio (100% in the case of the non-mixed material) are described as “color recipe”.

The drug selection process refers to a non-mixed material or a non-mixed material required for dyeing a desired color from dyeing materials (drugs) that can be used by hair salon users based on the undercolor and desired color of the hair of the person to be dyed. A process for selecting a mixed material and calculating the application amount of the selected material.
As shown in FIG. 6, the medicine selection process of the control unit 21 includes an under color setting process (step ST11) and a desired color setting process (step ST12). These setting processes are performed based on the setting information received from the client terminal 3.

The under color setting process (step ST11) includes setting the application site for the hair of the person to be dyed, setting the dyeing method for fashion dyeing or white hair dyeing, setting the application method, and setting the length and lightness of the application site. It is.
The desired color setting process (step ST12) is a process for setting the hair color desired by the person to be dyed according to the HSV value. In the present embodiment, a desired color is designated every 16 levels in tone, 10 levels in saturation, and 5 levels in lightness.

The control unit 21 of the server 2 converts the HSV value of the desired color determined by the desired color setting process into an RGB value (step ST14), and uses the converted RGB value for the color recipe search process (step ST13). .
The color recipe search process is performed based on the brightness of the application site and the RGB value of the desired color. The color recipe search process is a process of searching the database DB2 for the type and mixing ratio of the medicine that matches the brightness of the application site and the desired color.

The control unit 21 of the server 2 calculates the application amount for each application region based on the hair color before dyeing and the length of the application region and the color recipe of the search result among the set values of the under color (step ST15). The calculation result is output to the outside (step ST16).
The output calculation result is transmitted to the client terminal 3 via the public communication network 1. Thereby, the user of the client terminal 3 can immediately grasp the color recipe including the application amount for realizing the color desired by the person to be dyed.

[Specific example of color recipe search processing]
FIG. 7A is a flowchart showing a color recipe search process. FIG. 7B is a table showing search priorities. The search process in FIG. 7A is a specific example of the search process in step ST13 in FIG.

As shown in FIG. 7A, the control unit 21 of the server 2 first acquires the lightness of the application site of the person to be dyed and the RGB value obtained by converting the HSV value of the desired color (step ST21).
Next, the control unit 21 searches the database DB2 for RGB data suitable for the acquired brightness and RGB value of the application site (step ST22). For example, when the brightness of the application site is “14LV”, the control unit 21 searches the RGB data included in the “14LV” column of the database DB2 for a data string that matches the specified RGB value.

When there is a data string having the same RGB value, the control unit 21 employs the mixing ratio (color recipe) of the medicine corresponding to the data string as an output result (step ST24).
If there is no data string with the same RGB value, the control unit 21 extracts a data string that approximates the RGB value obtained by the binary search method (step ST23), and mixes the medicines corresponding to the data string. The ratio (color recipe) is adopted as the output result (step ST24).

As shown in FIG. 7 (b), the control unit 21 executes the search process of FIG. 7 (a), with one drug A being 100% (in the case of an unmixed material) as the first priority. To do.
The control unit 21 executes the search process of FIG. 7A so that the case where the medicine A and the medicine B are mixed by 50% each (in the case of equal mixing) has the second priority.
The control unit 21 executes the search process of FIG. 7A by setting the case where the medicine A and the medicine B are mixed at 25 to 75% (in the case of non-uniform mixing) as the third priority.

That is, the control unit 21 of the server 2 extracts the HSV value image file F (see FIG. 3) corresponding to the desired color being selected from the database DB1, and displays the extracted model image file F on the image display unit G. Let
Lightness adjustment tabs C25 are displayed on both the upper and lower sides of the image display unit G, and saturation adjustment tabs C25 are displayed on the left and right sides of the image display unit G.

Each time these adjustment tabs C25 and C26 are touched, the control unit 21 of the server 2 accepts an operation to change the brightness or saturation one step at a time, and receives the model image file F corresponding to the HSV value after the operation. It is displayed on the image display part G.
For example, when the adjustment tab C25 for increasing the brightness is touched, the image file F having an HSV value that is one level higher in brightness is displayed on the image display unit G. When the adjustment tab C26 for increasing the saturation is touched, an image file F having an HSV value that is one level higher in saturation is displayed on the image display unit G.

The operation screen of the selection result in FIG. 12 shows the operation screen when the operation icon C24 for confirming the desired color is selected on the operation screen for the desired color in FIG.
That is, when the user touches the operation icon C24 included in the pop-up screen P, the control unit 21 of the server 2 temporarily stores the HSV value corresponding to the desired color being selected in the storage unit 25.

Then, the control unit 21 of the server 2 calculates a color recipe (mixing ratio) for each application site from the stored brightness of the application site and the RGB value of the desired color (step ST13 in FIG. 6). Moreover, the control part 21 calculates the application quantity of the chemical | medical agent for every application site | part based on the hair amount and the length of an application site | part (step ST15 of FIG. 6).
Then, the control part 21 of the server 2 displays the operation screen of the selection result shown in FIG. 12 on the tablet terminal 3A.

In the operation screen of the selection result of FIG. 12, as a calculation result of the above-described application amount, combinations of dyeing materials (drugs) and weights (grams) necessary for dyeing each part A to C, and a drug ( The total weight of 1 agent and 2 agents) is displayed.
In FIG. 12, “one agent” means a dyeing material containing an oxidation dye and an alkaline agent, and “two agents” means an agent containing an oxidizing agent. That is, the dyeing material (one agent) of this embodiment is a hair color in which an oxidation dye develops color when two agents are mixed.

[Effect of selection system]
According to the selection system of the present embodiment, the control unit 21 of the server 2 inputs the desired color from the coordinate data corresponding to the type of the input under color (lightness level before dyeing in the present embodiment). Is searched for an unmixed material or mixed material whose coordinate values match or approximate, and the search result is output (see FIG. 7A), so an unmixed material or mixed material that realizes the desired color is automatically obtained. It is done.
For this reason, the dyeing material which implement | achieves a desired color can be rapidly shown to a user, and a user can respond now to a customer's request quickly and easily.

Further, according to the selection system of the present embodiment, the control unit 21 of the server 2 executes the search for the non-mixed material with the first priority (see FIG. 7B), so that the desired color is not realized. The possibility that the mixed material is output preferentially increases.
For this reason, compared with the case where a mixed material is output preferentially, the adjustment work of a dyeing material can be performed more simply and rapidly, and a customer's satisfaction can be improved.

According to the selection system of the present embodiment, the control unit 21 of the server 2 executes the search for the mixed material having the same mixing ratio with the second priority (see FIG. 7B), so that the non-mixed material If is not searched, there is an increased possibility that a mixed material having a uniform mixing ratio is output.
For this reason, compared with the case where the mixed material with an uneven mixing ratio is obtained preferentially, the adjustment work of the dyeing material can be performed more simply and quickly, and the customer satisfaction can be improved.

  According to the selection system of the present embodiment, the control unit 21 of the server 2 executes the search for the mixed material having an unequal mixing ratio with the third priority (see FIG. 7B). Even when a mixed material with an equal material or mixing ratio is not searched, a mixed material with an uneven mixing ratio is output. For this reason, the mixed material which implement | achieves a desired color can always be shown to a user.

  According to the selection system of the present embodiment, it is possible to input the hair amount of the person to be dyed and the length of the application site to the client terminal 3 that functions as an input unit that operates in conjunction with the server 2. Since the control unit 21 calculates the application amount of the non-mixed material or the mixed material after the search based on the input hair amount and the application site (step ST15 in FIG. 6), the application amount of the staining material is wasted. And can be calculated accurately.

  According to the selection system of the present embodiment, the client terminal 3 functioning as an input unit and a display unit linked to the server 2 includes a hair color face image corresponding to the desired color, and an operation unit for adjusting the desired color. Can be displayed (see FIG. 11B), and the control unit 21 of the server 2 displays the face image of the hair color corresponding to the desired color after adjustment on the client terminal 3, so that the user can perform the finished work after dyeing. The desired color can be selected while confirming.
