    摘要： The invention relates to a method and apparatus for characterizing the imperfections of the skin. The apparatus comprises: a) a digital camera allowing the taking of at least one digital image of at least one determined skin zone, the said image being defined by a multiplicity of pixels, that is transmitted to a digital image processing device; b) means of splitting the digital image into three colour planes: red, green, blue, termed R, G, B, with the aid of the said image processing device; c) means of extracting a single of these planes; d) means of calculating at least one of the following parameters on the basis of this plane: the mean grey level of the image; the surface area of the imperfections of the skin of the said image, some of which are related to aging, such as wrinkles, lines, spots, dark circles, pigmentary imperfections, slackening or loosening zones; the variance of the grey levels over the set of pixels of the image as parameter representative of the homogeneity of the skin. The invention finds an industrial application in a method of assessing the anti-aging effect of a cosmetic product.
