Description

Dispositif et méthode pour déterminer l'indice de protection solaire adéquat pour un individu : Device and method for determining the adequate sun protection index for an individual:
Là présente invention concerne un dispositif pour déterminer l'indice de protection de la lotion solaire que devrait utiliser un individu en fonction de la sensibilité de sa peau aux radiations lumineuses du soleil.The present invention relates to a device for determining the sun protection factor that should be used by an individual depending on the sensitivity of his skin to the sun's light radiation.
Il est bien connu des médecins et notamment des médecins dermatologues que l'exposition au soleil représente un risque pour la peau si cette dernière n'est pas protégée par une lotion solaire. Il est donc impératif de protéger sa peau en lui appliquant une lotion protectrice lors d'expositions au soleil. La sensibilité de la peau aux risques solaires varie selon les individus et il existe un lien entre sensibilité au soleil et teint de la peau.Èn effet.les peaux claires sont très sensibles et nécessitent donc l'utilisation d'une lotion solaire avec un indice de protection élevé. En revanche, une lotion avec un indice de protection moins élevé sera adéquate pour une peau mate moins sensible.It is well known to doctors and especially dermatologists that exposure to the sun is a risk for the skin if it is not protected by sun lotion. It is therefore imperative to protect your skin by applying a protective lotion during exposure to the sun. The sensitivity of the skin to solar risks varies between individuals and there is a link between sensitivity to the sun and skin tone. The effect is that light skin is very sensitive and therefore requires the use of sun lotion with a hint. high protection. On the other hand, a lotion with a lower degree of protection will be adequate for less sensitive skin.
Des médecins dermatologues ont proposé des classifications des différentes sortes de peau en fonction de leur sensibilité au rayonnement solaire.Ces classifications constituent des échelles distinguant entre 5 et 8 « phototypes » caractérisés en fonction du teint ou de la couleur de la peau et,souvent,également de la couleur des cheveux.La connaissance du phototype d'un individu est utile pour déterminer l'indice de protection solaire dont il a besoin.Toutefois.les phototypes sont peu connus du consommateur qui,jusqu'ici,ne disposait pas vraiment de moyen simple pour déterminer lui- même celui qui correspond à sa propre peau.Dermatologists have proposed classifications of the different types of skin according to their sensitivity to solar radiation. These classifications constitute scales distinguishing between 5 and 8 "phototypes" characterized according to the complexion or the color of the skin and, often, The knowledge of an individual's phototype is useful in determining the sun protection factor he needs. However, the phototypes are little known to the consumer who, until now, did not really have simple way to determine himself the one that corresponds to his own skin.
Un but de la présente invention est donc de fournir un dispositif permettant à chacun de connaître l'indice de protection solaire dont il a besoin en déterminant quel phototype correspond à sa peau. Le document de brevet US 6'452'188 décrit déjà un dispositif pour déterminer , la pigmentation de la peau par comparaison avec un jeu de surfaces de référence. Ce dispositif comprend un filtre qui laisse passer uniquement la lumière dans une bande particuliaire du spectre visible.qui correspond à la lumière rouge. Le dispositif comprend également un échelle de niveaux de gris constituée de plages plus ou moins sombres sur un support.Pour utiliser ce disposition positionne l'échelle de niveaux de gris à proximité de la peau en haut de la jambe. Ensuite, on observe simultanément l'échelle et la peau en regardant à travers le filtrè.pour déterminer le niveau de gris dont la luminosité apparente correspond le mieux à la luminosité apparente de la peau.Finalement,le dispositif comporte des indications faisant correspondre chaque niveau de gris à un phototype. Pour résumer.on peut dire que le document de brevet US 6'452'188 enseigne de mesurer le niveau de réflectance de la peau pour la lumière rouge comme moyen de déterminer le phototype.An object of the present invention is therefore to provide a device allowing everyone to know the sun protection index he needs by determining which phototype corresponds to his skin. Patent document US 6'452'188 already discloses a device for determining, pigmentation of the skin compared with a reference surface set. This device comprises a filter which passes only the light in a particular band of the visible spectrum which corresponds to the red light. The device also includes a greyscale scale consisting of more or less dark areas on a support.To use this arrangement positions the greyscale scale near the skin at the top of the leg. Then we simultaneously observe the scale and the skin looking through the filter to determine the gray level whose apparent brightness best matches the apparent brightness of the skin. Finally, the device has indications that correspond to each level. from gray to a phototype. To summarize, it can be said that US Pat. No. 6,452,188 teaches to measure the level of skin reflectance for red light as a means of determining the phototype.
Un tel dispositif présente certains incovénients.Bien qu'il soit peu coûteux en comparaison, par exemple, avec un réflectomètre de laboratoire, le coût de production de ce dispositif serait probablement encore trop élevé pour qu'il soit réaliste, par exemple,de le distribuer gratuitement lors de campagnes de prévention ou même comme publicité pour une marque de lotion solaire.D'autre part,bien que le mode de mise en œuvre de ce sispositif soit relativement simple.son caractère technique pourrait dissuader le baigneur moyen. Finalement.on sait que la vision humaine permet de distinguer les couleurs. On peut donc considérer que le fait de regarder à travers un filtre, ne laissant passer que le rougê.fevient â perdre des informations potentiellement utiles.Ainsi.bien qu'habituelle dans le contexte du laboratoire, l'utilisation d'un filtre pourrait s'avérer contreproductive avec un dispositif destiné à être utilisé par des non-spécialistes. En conséquence.un autre but de ia présente invention est de remédier aux inconvénients susmentionnés en fournissant un dispositif conforme à la revendication 1 et une méthode conforme à la revendication 2.Such a device has some disadvantages. Although inexpensive in comparison, for example, with a laboratory reflectometer, the production cost of this device would probably still be too high to be realistic, for example, the distribute free of charge during prevention campaigns or even as advertising for a brand of sun lotion. On the other hand, although the mode of implementation of this device is relatively simple. Its technical nature could dissuade the average swimmer. Finally, we know that human vision makes it possible to distinguish colors. We can therefore consider that the fact of looking through a filter, allowing only redness to pass through, can lead to the loss of potentially useful information. Thus, although usual in the context of the laboratory, the use of a filter could counterproductive with a device for use by non-specialists. Accordingly, it is another object of the present invention to overcome the above-mentioned disadvantages by providing a device according to claim 1 and a method according to claim 2.
On comprendra que la présente invention utilise une pluralité d'images de peau en couleur,plutôt qu'une échelle de niveaux de gris comme enseigné dans le document antérieur. Grâce à cette caractéristique, la détermination du phototype peut se faire directement à l'œil nu et à la lumière du jour sans utiliser un filtre.Ainsi.un premier avantage de la présente invention est son coût de fabrication très bas, puisque le dispositif ne comporte pas de filtre optique. Un deuxième avantage de la présente invention est également lié à l'utilisation d'images de peau en couleur plutôt que d'une échelle formée par des plages ayant chacune une teinte uniforme^En effet.les images permettent de représenter également des éventuelles irrégularité de la peau, comme par exemple des taches de rousseur.La prise en compte de ces irrégularités peut éventuellement permettre d'affiner la détremination d'un phototype, Un troisième avantage de la présente invention et de sa mise en œuvre est extrêmement simple.It will be appreciated that the present invention utilizes a plurality of color skin images, rather than a gray scale as taught in the prior art. Thanks to this characteristic, the phototype can be determined directly by the naked eye and in the light of the day without using a filter. Thus, a first advantage of the present invention is its very low manufacturing cost, since the device has no optical filter. A second advantage of the present invention is also related to the use of skin color images instead of a ladder formed by beaches, each having a uniform shade ^ In effet.les images help also represent potential irregularity the skin, such as freckles. Taking these irregularities into account may possibly make it possible to refine the deletion of a phototype. A third advantage of the present invention and its implementation is extremely simple.
D'autres caractéristiques et avantages de la présente invention apparaîtront à la lecture de la description qui suit, e donnée uniquement à titre d'exemple, d'un mode de réalisation particulier de l'invention. Le dispositif de la présente invention comporte un support papier ou plastique de la forme d'une carte de crédit sur laquelle sont imprimées six images représentant respectivement six spécimen de peau correspondant aux six phototypes de la classification donnée par le site internet de Météo France (www.meteo.fr/métêonet/dêcouvr/dossier/uv/uv.htm).Ces six phototypes sont définis de la façon suivante :Type I :Peau claire .laiteuse avec de nombreuses taches de rousseur.Type II :Peau claire avec peu de taches de rousseur.Type III :Peau claire sans tache de rousseur.Type IV :Peau mate.Type V :Peau très mate.Type Vl :Peau noire, On comprendra que le choix de cette classification est arbitraire et que la présente invention pourrait utiliser d'autres classifications en phototypes. En regard de chaque spécimen de peau représenté sur le dispositif est inscrit l'indice de protection solaire le mieux adapté. Pour déterminer l'indice de protection solaire, il suffit d'amener le dispositif de la présente invention à proximité de la peau à examiner, par exemple au niveau du bras, et l'image du dispositif correspondant le mieux à ladite peau à examiner indique son phototype et l'indice de protection solaire recommandé correspondant.Other features and advantages of the present invention will appear on reading the description which follows, given solely by way of example, of a particular embodiment of the invention. The device of the present invention comprises a paper or plastic support in the form of a credit card on which six images representing respectively six skin samples corresponding to the six phototypes of the classification given by the Météo France website (www. These six phototypes are defined as follows: Type I: Clear skin. Milky with many freckles. Type II: Clear skin with few skin types. Freckles.Type III: Clear skin without freckles.Type IV: Matt skin.Type V: Skin very matt.Type Vl: Black skin, It will be understood that the choice of this classification is arbitrary and that the present invention could use other classifications in phototypes. Next to each skin specimen represented on the device is written the sun protection index best suited. In order to determine the sun protection index, it suffices to bring the device of the present invention close to the skin to be examined, for example at the level of the arm, and the image of the device corresponding best to said skin to be examined indicates its phototype and the corresponding recommended sun protection factor.
Un autre exemple de réalisation du dispositif comporterait en plus ou au lieu des six spécimens de peau correspondant aux six phototypes, les images en couleurs de portraits de têtes comportant les cheveux et les yeux des six phototypes décrits sur le site internet de Météo France. Another embodiment of the device would include in addition to or instead of six skin specimens corresponding to six phototypes, the color images of portraits of heads including the hair and eyes of the six phototypes described on the website of Météo France.
