EP0569291B1 - Procedure for the making-up of a face, in particular the eyes and a device for carrying out the same - Google Patents

Description

The present invention essentially relates to a method for making up the face, in particular the eyes, and a device for carrying it out. More particularly, the invention relates to a process for personalized make-up of the eyes (upper and lower eyelids, internal edge of these eyelids, eyelashes and eyebrows), as well as a device to assist in the choice of shades of make-up products.

Until now, face makeup, in particular eye makeup, has been carried out empirically and is not very personalized. When it was desired to harmonize the shades of make-up with the color of the eyes, one generally limited oneself to the use of a relatively limited number of shades of make-up adapted to only the colors of the major classes of eyes (black, brown, blue and green).

Thus, document US-A-4,561,850 describes a color coordination device offering make-up products taking into account the general color of the skin and the general color of the eye (see column 1, line 55 in column 2 , line 2 and column 4, lines 4 to 6).

In fact, no one had planned to make the makeup more personal to reproduce therein, in a very precisely adjusted manner, the different individual colors characteristic of the iris of the eye of each individual. Thus, many of these precise shades did not exist, especially in the form of pencils or eye shadows, and those which existed were for the most part dispersed between different points of sale, being able to be geographically very distant from each other. It was therefore practically impossible to make, with commercial makeup products, make-ups of the face, and in particular of the eyes, which were particularly personalized and taking into account the various colored shades characteristic of each iris.

Furthermore, in a completely different field of makeup, the document WO86 / 05.018 describes a method and a device for identifying a person by using the structure and essentially geometric characteristics of the pupil and the iris of a person. for identification.

The present invention therefore aims to solve the new technical problem of providing a solution for making personalized make-up of the face, in particular of the eyes, and to facilitate the choice of product shades to make such make-up.

The invention also proposes to provide a simple solution to this problem usable by a person without special training.

The present invention is based on the discovery of the fact that it was possible to obtain personalized make-up and of great aesthetic value by analyzing the various colored areas of the iris and that the richness of the characteristic colors of the irises enabled to create new, more nuanced shades and to enrich the existing shades of makeup products.

Indeed, it has been observed that although in a relatively limited number, these different individual colors generate, because of their location and their extent in the iris, an infinity of combinations, each combination being in practice characteristic of an individual .

Thus, according to a first aspect, the present invention provides a method of making up the face, in particular of the eyes, according to which, firstly, the different individual colors of the iris of the eye of the face to be made up are determined, comprising at least the color (s) of iris shine or the contour color of the iris by appropriate technical means of determining colors, and, in a second step, the areas to be made up are applied with face one or more make-up products whose shade corresponds to at least one of these individual colors of the iris, in order to carry out personalized make-up of the face, in particular of the eyes.

It will be specified that, in the present description, the term "correspondence" is understood to mean between the shade of a makeup product and an individual color of the iris, the fact that this shade is substantially identical to said individual color, or else that it has been previously chosen by an expert in the make-up field, as being able to agree, from an aesthetic point of view, with said individual color.

It will also be specified that, within the meaning of the present invention, the expression "personalized make-up" means that the different individual colors of the iris are taken into account, with great precision, that is to say these different colors very precisely, that is to say make-up products are used, the hue of which has been matched to one of these very precise colors.

According to a second aspect, the present invention also provides a method of assisting in the choice of shades of face makeup products, in particular eye makeup, according to which one or more individual colors of the iris of the eye are determined. of the face to be made up, comprising at least the color (s) of radiance of the iris or the contour color of the iris, by means appropriate techniques for determining colors, and at least one of these colors is used as a reference shade in the choice of makeup products, with the aim of producing personalized makeup for the face, in particular for the eyes.

According to a particular variant embodiment of any of the aforementioned methods of the invention, at least the color (s) of radiance of the iris and the contour color of the iris are determined.

According to another particular variant embodiment, the printing color of the iris is also determined.

By the expression "contour color" of the iris, is meant the color of the iris located at its periphery.

By the expression "printing color" of the iris is meant the dominant color of the iris. In practice, this printing color can be a color resulting from the average or from the integration of all the interior colors of the iris, between the contour color of the iris and the pupil.

By the expression "radiance color" of the iris, is meant the color of the different points, or spots of small dimensions, distributed over the surface of the iris between the pupil and the contour. Each iris generally comprises from 1 to 5 brightness colors. Bright colors generally give the eye most of its personality.

According to a particular embodiment of the abovementioned methods of the invention, the iris is illuminated with a determined light, for example daylight or the light of a lamp with defined characteristic (s), and we take a color image of the iris with a color image taking device, such as a camera preferably comprising a function for digitizing the image, or a color video camera preferably having very good chromatic performance.

According to a particular variant embodiment, the location and the surface of the areas of each of the colors which characterize the iris are determined and the results are used to determine the outline color, the color (s) of radiance and the color printing.

According to a particular embodiment of the invention, pencils, such as kohl pencils or "eyeliner" pencils, mascaras, eyeshadows or eye shadows are chosen or used as make-up product. pressed powders, blushes or lipsticks.

Advantageously, the pencils preferably correspond to the outline and printing colors, the mascaras preferably correspond to the outline color, and the eyeshadows or eyeshadows, as well as the blushes and the lipsticks, preferably correspond to the colors. of radiance.

According to another particular embodiment of the abovementioned methods of the invention, a specific step is made to correspond, in a prior step, to different particular combinations of individual iris colors, in particular outline, printing and brightness colors and, for each of these combinations, one or more lists of make-up products, each list making it possible to produce a particular type of make-up whose hue or shades correspond to one or more colors of said combination, and then, after having determined the individual colors of the iris of the face to be made up, the comparison is made between the combination of colors of this iris on the one hand, and the various particular combinations mentioned above on the other hand, so as to determine which of these is the one which is the most close to the iris concerned, or where appropriate which are the closest, thus making it possible to obtain one or more lists of pr make-up odors so as to make personalized make-up of the face, in particular of the eyes.

Preferably, the aforementioned particular combinations of individual colors of iris are chosen so that they together constitute a representative sample of a population of individuals concerned. Advantageously, several variants of color combinations are chosen from each class of the classification of eye colors described below. The number of these particular combinations used for the implementation of the aforementioned particular embodiment is generally between 50 and 150, preferably between 80 and 110.

• on prend une image en couleur de l'iris avec un dispositif de prise d'images couleurs tel qu'un appareil photographique ou une caméra vidéo couleur précitée,
• à l'aide d'un dispositif d'analyse d'image notamment mis en oeuvre avec l'emploi de calculateur tel que micro-ordinateur, on réalise un repérage de la pupille et son retrait de l'image.
• ensuite, on repère le contour de l'oeil par différence entre le blanc de l'oeil et la couleur de l'oeil, ce qui permet ensuite de déterminer la couleur de contour de l'iris à la limite du blanc de l'oeil.
• on retire ensuite la couleur de contour et on réalise une moyenne ou une intégration de l'ensemble des couleurs intérieures de l'iris situées entre la couleur de contour et la pupille d'où il en résulte la couleur d'impression.

According to a particularly advantageous embodiment of the method of the invention, the eye is illuminated by centering the lighting on the pupil, which can be carried out easily, for example using optical fiber (s) . Once the centering is done on the pupil,

• a color image of the iris is taken with a color image taking device such as a photographic camera or a color video camera mentioned above,
• using an image analysis device notably implemented with the use of a computer such as a microcomputer, the pupil is identified and its image removed.
• then, the eye contour is identified by difference between the white of the eye and the color of the eye, which then makes it possible to determine the color of the outline of the iris at the limit of the white of the eye .
• the outline color is then removed and an average or integration of all the interior colors of the iris situated between the outline color and the pupil is produced, from which the printing color results.

In the case of taking a color image with a color video camera, we search for the color (s) of iris brightness using the pixels processed automatically by the computer in order to give a refined iris . On the refined iris, we define a matrix and by contrast we determine the brightness colors.

In the particular case of a color photo, we can film this photo with a color video camera to define the outline, print and brightness colors as previously described, but to obtain a better quality of result, we preferably use a camera with an image digitization function.

Furthermore, the studies carried out by the applicant on a large number of irises have shown that the different existing individual colors can be related to a palette of colors in limited numbers, ranging from very dark brown to black, passing through different shades more clear, such as medium brown, light brown, ocher, putty, pale yellow, gray, turquoise, lavender, gray-blue, verdigris, khaki, pine green, blue with purple hues, navy blue and dark blue.

A range of make-up products has thus been produced, which is the subject of a request divisional to this request.

The preparation of said makeup products can be carried out according to techniques well known to those skilled in the art, using the appropriate pigments available commercially.

According to a third aspect, the present invention also provides a device for assisting in the choice of shades of makeup products, characterized in that it comprises means for lighting the iris under determined lighting conditions, means for taking a color image of the iris, as well as calculation means capable of determining at least the color (s) of radiance of the iris or the contour color of the iris and possibly the color d printing of the iris, from the color image supplied by the color image capture means.

According to a particular embodiment, commercial lighting means are used, preferably of the annular lighting type for stereoscopic microscopy, in particular in the form of an O-ring tube with neon, or preferably fiber optic lighting type, such as the "Fiber optic L 151®" model from the company Heim AG (Switzerland). Advantageously, the lighting means produce a light called "daylight" or "northern light".

According to another particular variant embodiment, the color image taking means of the iris comprise a color video camera, preferably having very good chromatic performance, transmitting light information to calculation means, for example a micro- computer or computer, equipped with a video card, and advantageously display means such as a screen and / or a printer. Advantageously, the calculation means make it possible to evaluate the brightness characteristics and the chromatic characteristics, for example in RGB coordinates, and to quantify the light information received in the form of signals transmitted by the video camera via said video card. They also include in memory different particular combinations of individual iris colors, as well as, associated with each of these, one or more lists of makeup products, for example in the form of commercial references, and can display on the means of display, on the one hand, the different individual colors of the iris analyzed, and on the other hand the different list (s) of makeup products corresponding to the different individual colors of this iris, taken individually or in combination with one another.

Advantageously, these different individual colors of the iris analyzed are classified in brightness, outline and printing colors.

According to another particular embodiment, the aforementioned image taking means comprise a photographic camera and a color film as well as means for developing into photographic images, and preferably a device comprising an image digitization function to allow to determine the individual colors according to their location in the iris.

According to another alternative embodiment of the device, the calculation means also determine the location and the surface of the individual color ranges which characterize the iris.

Thus, thanks to the invention, it is possible to determine in a simple, reliable, substantially inexpensive manner, without special training, the individual colors of the iris which can be used as basic colors in the choice of products of make-up to make personalized make-up of the face, in particular of the eyes.

We can thus foresee that the calculation means are capable of determining a list of recommended products, with possibly several variants in each range of make-up products available commercially, or preferably in a range of make-up products according to the present invention, protected by a divisional request for this request, and to print using a printer this list which is presented to the person whose iris has been analyzed in this way.

• la figure 2 est une vue schématique illustrant un dispositif d'aide au choix de teinte de produits de maquillage conforme à l'invention.
• les figures 3 à 5 représentent schématiquement trois maquillages personnalisés différents du même oeil, mettant en oeuvre le procédé de l'invention au moyen de produits de maquillage choisis dans la gamme de l'invention.

Other objects, characteristics and advantages of the invention will appear in the light of the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of nonlimiting examples illustrating a currently preferred embodiment of the invention. , and in which:

• Figure 1 is a schematic front view of an eye showing the different characteristic areas of the iris;
• Figure 2 is a schematic view illustrating a device for choosing the shade of makeup products according to the invention.
• FIGS. 3 to 5 schematically represent three different personalized make-ups of the same eye, implementing the method of the invention by means of make-up products chosen from the range of the invention.

There is therefore shown schematically in Figure 1 a front view showing an eye.

For reasons of clarity of the figure, the colored zones have only been represented on one sector of the iris, but, of course, these zones are distributed over the whole of the iris.

The reference number 1 generally designates the iris, the number 2 the pupil, the number 3 the lower edge of the upper eyelid and the number 4 the upper edge of the lower eyelid.

The characteristic colored areas of the iris have generally been designated by the letters c for the area corresponding to the outline color, i for the area corresponding to the printing color and e₁, e₂, e₃ for the areas corresponding to the different colors. radiance (three different colors in the example shown).

c :

brun très foncé

i :

brun foncé

e₁ :

ocre-jaune

e₂ :

vert foncé

e₃ :

brun clair.

As a purely illustrative example, a dark hazel eye can have the following colored areas:

vs :

very dark brown

i:

dark brown

e₁:

yellow ochre

e₂:

dark green

e₃:

light brown.

The observation of the characteristic colors of the eyes of a hundred people made it possible to establish a classification of the eye colors given in Table I, the definitions making it possible to establish this classification being moreover given in Table II.

In Table II, the mentions "c", "i" and "e" indicate that the colors mentioned are generally, and respectively, colors of outline, impression and brightness.

FIG. 2 shows schematically a device for assisting in the choice of shade of makeup products in accordance with the present invention.

This device generally comprises means 5 for lighting the iris under determined lighting conditions; color image taking means 6 of the iris as well as calculation means 7 making it possible to determine in particular the location, the chromatic coordinates, the intensity and the surface of the individual color zones which characterize the iris.

This device may further comprise a means for holding the head such as for example a headrest, and possibly a chin rest, but preferably an articulated arm carrying a camera is used, the objective of which is situated in an eyepiece. The eyepiece is preferably in the form of a tube, the length of which makes it possible to obtain a focal length preset, which can be refined by means of an adjustable end of focal length such as a wheel, as is well known in one skilled in the art.

The aforementioned lighting means 5 generally comprise at least one lamp, for example a neon luminescent O-tube generating light of the daylight or northern light type. This O-tube will for example have an outside diameter of 7 cm and an inside diameter of 5 cm. Preferably, instead of the luminescent tube, fiber optic lighting will be used as the lighting means, for example having an outlet section of approximately 5 mm in diameter. Two optical fibers can be used, arranged on either side of the shooting lens, the lighting light of which is centered on the pupil, which can allow, in certain cases, when the pupil is removed from the image, also removing the image from the light beam which usually constitutes a slight disturbance in the determination of colors.

The color image taking means of the iris 6 generally comprise a color video camera having good chromatic performance such as for example a CCD type camera.

Preferably, the lens of the video camera is placed in the center of the O-tube, as shown in Figure 2. When using fiber optic lighting, it is placed near the lens of the camera , and directed towards the eye to be analyzed by centering the light on the pupil.

This video camera is connected to calculation means 7 comprising for example a microcomputer advantageously equipped with display means such as a screen and a printer.

The image obtained by the video camera is stored via the video card, then processed by the microcomputer. This can advantageously be equipped with a microprocessor of the 80/386 type, or preferably 80/486, with a hard disk of 40 megabytes. The screen will advantageously be a V.G.A.type color screen.

The calculation means 7 make it possible to determine the brightness characteristics and the chromatic characteristics, for example in RGB coordinates of each individual color of the iris, that is to say the different colors of the outline, of printing and of 'previously defined brightness.

For this, and in accordance with the method described previously in the introductory part of this description, after having identified the pupil and removing it from the image, the image analysis means look for the outline color by difference between the white of the eye and the iris, at the edge of the iris to define an outline color of the iris.

Then, the image analysis means remove the outline color and perform an average or an integration of all the interior colors of the iris defined between the outline of the iris and the pupil to determine a color of impression.

Finally, the brightness color (s) are sought from the pixels of the image, which gives a refined iris. From the purified iris, the image analysis means form a matrix which, by contrast, determines the colors of brightness.

The data thus obtained are compared with a database grouping together different particular combinations of iris colors, generally corresponding to a certain number of characteristic eyes, with which one or more lists of makeup products are associated.

Thus, after comparison with this database, the aforementioned calculation means make it possible to determine a list of recommended products, with possibly several variants in each range of make-up products available on the market such as eyeshadows, mascaras or pencils. , or preferably in a range of makeup products according to the invention, and to print using a printer 8 this list which is presented to the person whose iris has thus been analyzed.

It should be noted that the aforementioned database can be enriched by new combinations of iris colors, in particular during analyzes such as those mentioned above.

FIGS. 3 to 5 show, for the same face, three different personalized make-ups, after having implemented the methods of the invention, by means of make-up products chosen from a range of products of the invention.

• couleur de contour : bleu-gris foncé (c)
• couleur d'impression : gris-bleu moyen (i)
• couleurs d'éclat :
  • turquoise bleuté très clair (e₁)
  • ocre-jaune doré (e₂)
  • gris-turquoise très clair (e₃)
  • lavande claire (e₄)

   Les produits de maquillage conseillés pour ce visage, choisis dans la gamme de produits selon l'invention ont été rassemblés dans le tableau III ci-après. La teinte de chaque produit, figurant dans ce tableau par sa référence commerciale, est sensiblement identique à la couleur individuelle correspondante de l'iris.Analysis of the iris of the eyes of this face gave the following results:

• outline color: dark blue-gray (c)
• print color: medium gray-blue (i)
• brightness colors:
  • very light bluish turquoise (e₁)
  • ocher-golden yellow (e₂)
  • very light gray-turquoise (e₃)
  • light lavender

The makeup products recommended for this face, chosen from the range of products according to the invention have been collated in Table III below. The color of each product, appearing in this table by its commercial reference, is substantially identical to the corresponding individual color of the iris.

In FIGS. 3 to 5, the references indicated are those of the recommended makeup products. TABLE III Individual iris colors Eyeshadows Pencils Mascaras Blushes Lipstick vs C34 M34 i C27 e₁ F18 e₂ C7 B7 R7 e₃ F17 e₄ F19

It is specified that the blush B7 and the lipstick R7, both of ocher-golden yellow hue, were only recommended in the case of the makeup of FIG. 4.

Thus, for the makeup of FIG. 3, the pencil C27 is applied to the upper eyelid, above the upper eyelid the shadow F17 inwards and the shadow F18 outwards and, on the eyelashes, the mascara M34.

For the makeup of FIG. 4, the pencil C27 is applied to the upper eyelid, to the inner edge of the lower eyelid the pencil C34, to the shadow F18 on the lower eyelid, above the shadow F18, and M34 mascara on the lashes.

For the makeup of FIG. 5, the pencil C7 is applied to the upper eyelid, to the inner edge of the lower eyelid the pencil C27, to the shadow F17 on the lower eyelid, above the upper eyelid the shadow F17 towards the inside and the F19 eyeshadow outwards, and on the lashes, the M34 mascara.

Thus, for the iris of the present example, constituting a certain particular combination of outline, printing and radiance colors, it is possible to propose three lists of makeup products, presented in Table IV below. It also indicates the recommended areas for their application.
