BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vanity table with a skin color evaluation function that evaluates the degree of makeup applied to the skin so that when applying makeup, the makeup can be easily applied with a desired chromaticity.

0002

[Background Art] As technology advances, people's lives have become richer, and various functions have been added to the appliances they use on a daily basis, making them more convenient.

[0003] In recent years, in the makeup culture, not only women but also men have started to wear makeup.

However, the way you apply makeup varies depending on the lighting conditions, and
As more and more women are working, they have less time to put on makeup, and there is a growing desire to wear makeup that is easier and always looks beautiful. Also,
Young people who are starting to wear makeup for the first time do not know how much makeup they should wear, and therefore there is a demand for an indicator of what color should be used.

[0005] Furthermore, the present age is said to be an era of individualization, and there is a growing desire to easily express one's individuality.

[0006]

[Problem to be Solved by the Invention] However, even if one wants to reproduce the makeup that one likes in the same way, it has been difficult to reproduce it because there is no standard index. As a result, it takes a lot of time to apply makeup, and if you apply makeup under different lighting conditions, you may end up applying makeup that is completely different from what you had in mind. There was a need for a guideline for this, but until now no such thing existed.

[0007] The present invention solves the above problems.
To provide a standard for easily reproducing makeup that is generally recognized as preferable or makeup that suits each person's taste by realizing a makeup table with skin color evaluation.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides, as a first means, a method for applying light to the user's makeup skin that is reflected by illumination light from an illumination light source that illuminates the user's makeup skin. The light receiving section receives the reflected light, and the calculation section calculates the spectral reflectance of the user's makeup skin and the chromaticity value of the user's makeup skin from the intensity of the received reflected light in each wavelength range, and calculates the desired skin color. Chromaticity value (x, y, Y) = (0.369, 0.350
, 30) and the calculated chromaticity value of the user's makeup skin is calculated in the calculation unit, and the calculated result is displayed on the display unit in the form of numerical values or a chromaticity diagram. It is designed to evaluate the condition of the skin.

[0009] The present invention also provides, as a second means, a light-receiving unit that receives light reflected from the user's makeup skin by the illumination light from the illumination light source unit that illuminates the user's makeup skin;
The chromaticity value of the makeup skin that the user prefers is input into the input section, or the reflected light of the makeup skin that the user has actually applied makeup to the user's preference is received by the light receiving section. One of the chromaticity values output from the calculation unit that calculates the spectral reflectance and the chromaticity value of makeup skin from the intensity of the reflected light in the wavelength range is stored in the storage unit, and the received light is used. The spectral reflectance of the user's makeup skin and the chromaticity value of the user's makeup skin are calculated from the intensity of reflected light in each wavelength range from the user's makeup skin, and the memory is input by the user through the input unit or light receiving unit. The calculation unit calculates the color difference between the chromaticity value of the preferred skin color stored in the unit and the calculated chromaticity value of the user's makeup skin, and the calculated result is displayed on the display unit in the form of numerical values or a chromaticity diagram. In this way, the degree of makeup skin color of the user is evaluated.

0010

[Action] Human skin color changes depending on factors such as age, body part, gender, climate, region, etc., so it provides an objective physical quantity that indicates how the preferred makeup skin color differs from the skin color of each person. This is very effective. Therefore, according to the above-mentioned means, the chromaticity value of the skin of a person wearing makeup is sequentially measured, and the measured chromaticity value is compared with a preferred chromaticity value to objectively determine the current makeup skin color. It is possible to easily bring the makeup skin color of each person close to the desired skin color chromaticity value at any time.

[0011] In addition, human tastes vary widely, and we have entered an era in which each individual's individuality is emphasized. Therefore, each individual's preferred makeup skin color is memorized, and the memorized skin color chromaticity values are applied to each individual. It is very effective to provide an objective physical quantity as an indicator of how the skin color differs from the individual's skin color. Therefore, according to the second means described above, the chromaticity values of the skin of a person wearing makeup are sequentially measured, and the measured chromaticity values are compared with the stored chromaticity values of the makeup skin. It is possible to objectively evaluate the current makeup skin color state and easily bring the makeup skin color of each person closer to the stored skin color chromaticity value at any time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A dressing table with skin color evaluation according to an embodiment of the present invention will be described below with reference to the drawings.

(Example 1) In the makeup, photography, and printing industries, many studies have been conducted on what colors can be used to achieve preferable color reproduction in order to make human skin tones look more beautiful (for example, Nishimura et al. Take et al.; “Preferable color reproduction of color television images”, Television, 28, 8
, (1974), pp. 623-632). In general, Japanese people prefer a skin tone that is brighter than their natural skin color and tends to have a slight reddish tinge.

[0014] Therefore, from various industries researching the color reproduction of Japanese skin tones, four documents were cited to determine the chromaticity value of the preferred skin tones of Japanese women. The total number of subjects used in the literature is approximately 500. the result,
CIE (1931) Expressed in x, y chromaticity values (x, y,
Y)=(0.369, 0.350, 30).

FIG. 3 shows the chromaticity values of Japanese women's preferred skin color obtained through data analysis. In FIG. 3, the horizontal axis indicates the x-axis of the CIE 1931 x,y chromaticity diagram, the vertical axis indicates the y-axis, and the circles indicate preferred color reproduction regions.

Since the human color difference discrimination ability is generally 1 or more in terms of color difference, the preferred color reproduction area is (x, y, Y
)=(0.369, 0.350, 30) and includes a region with a color difference of 1 in all directions of the color space.

An embodiment of a dressing table with skin color evaluation according to the present invention will be explained based on a block diagram 1. In Figure 1, 1

(1976) calculate x, y, Y chromaticity values. after that,
The color difference between the calculated chromaticity value of makeup skin and the chromaticity value of Japanese women's preferred skin color was calculated using the CIE (1976) color difference formula, and the actual chromaticity value of makeup skin and the preferred skin color were calculated using the CIE (1976) color difference formula. It outputs signals corresponding to each degree value and their color difference. The display unit 4 displays the actually measured chromaticity value of the makeup skin, the chromaticity value of the preferred skin color, and the value of their color difference corresponding to the signal from the calculation unit 3 in numbers, or displays the chromaticity diagram shown in FIG. 3. Displays the chromaticity value as a dot above. Furthermore, when the color difference value between the measured chromaticity value of the makeup skin and the chromaticity value of the preferred skin color becomes 1 or less, a lamp on the display section may indicate that the makeup skin color has been reproduced to the preferred skin color. can. Here, the color difference 1 is the limit color difference at which a human feels that the colors are different when looking at the colors. The value displayed on the display unit 4 provides the vanity user with the color difference value between the chromaticity value of the current makeup skin color and the chromaticity value of the preferred skin color of Japanese women. With this configuration, it is possible to realize a device that objectively evaluates the makeup skin tone of the person using the vanity table, and through simple physical sequential measurement, it is possible to determine the preferred skin tone of Japanese women for each individual. It can be used as a powerful means to reproduce this.

(Example 2) As each individual becomes more individualized, we are living in an era where it has become a reality to express oneself and to express one's sense of the season as the seasons change. . Therefore, there is a need for a simple measuring device that allows each individual to express their preferred skin color according to their location, time, and atmosphere.

An embodiment of the dressing table with skin color evaluation according to the present invention will be described with reference to FIG. In FIG. 2, 1 is an illumination light source section, 2 is a light receiving section, 3 is a calculation section, 4 is a display section, 5 is a storage section, and 6 is an input section.

The light receiving section 2 receives the spectral radiant flux of a reflective object, ie, makeup skin, illuminated with the illumination light from the illumination light source section 1, and outputs a signal corresponding to the intensity thereof. The calculation unit 3 inputs the signal from the light receiving unit 2 and calculates the calculation CIE (1931) x, y, Y chromaticity values. Thereafter, the color difference between the calculated chromaticity value of the makeup skin and the chromaticity value of the preferred skin color previously stored in the storage unit 5 is calculated using the CIE (1976) color difference formula, and the actually measured makeup skin color is calculated. It outputs signals corresponding to the chromaticity value, the stored chromaticity value of the preferred skin color, and the color difference thereof. In addition, from the input unit 6, each individual's preferred skin color is input to the CI
E (1931) Input x, y, Y chromaticity values and store in storage unit 5.
Output to. The signal corresponding to the preferable chromaticity value output from the input section 6 is input to the storage section 5 and stored therein. Also,
Instead of inputting the chromaticity value from the input unit 6, the light receiving unit 2 is illuminated with the illumination light from the illumination light source unit 1. Preferred makeup that the user of the vanity table would like to memorize is the actual makeup applied. Receives the spectral radiant flux of the skin, outputs a signal corresponding to its intensity, inputs the signal from the light receiving section 2 to the calculation section 3, and calculates the CIE (1931) x, y, Y chromaticity values. However, the calculated chromaticity value of the makeup skin can be stored in the storage unit 5.

The display unit 4 displays the actually measured chromaticity value of the makeup skin corresponding to the signal from the calculation unit 3, the chromaticity value of the preferred skin color stored in the storage unit 3, and the value of the color difference between them. The chromaticity values are displayed numerically or as points on a chromaticity diagram as shown in FIG. Also, when the color difference value between the measured chromaticity value of the makeup skin and the chromaticity value of the stored preferred skin color becomes 1 or less, it is displayed that the makeup skin color has been reproduced to the stored preferred skin color. It can also be displayed using the lamp in the section. Here, the color difference 1 is the limit color difference at which a human feels that the colors are different when looking at the colors. In this way, the display section 4
