The invention concerns a method and an apparatus for characterizing skin blemishes. The apparatus comprises: a) a digital camera (12) for forming at least one digital image (14) of at least one specific region of the skin (34, 36, 38, 40), said image being defined by a plurality of pixels, which is transmitted to a digital image processing device; b) means for digitally breaking down the digital image into three color planes: red (60), green (70), blue (80), called R, G, B, using said image processing device; c) means for extracting only one of said planes (80); d) means for computing at least one of the following parameters from said plane: the average grey level of the image; the surface or area of skin blemishes of said image, some of which are related to aging, such as wrinkles, fine lines, spots, rings, pigmentary blemishes, slackening regions; the grey level variance over the pixel assembly of the image as a parameter representing the homogeneity of the skin. The invention is industrially applicable in a method for assessing the anti-aging effect of a cosmetic product. |
