The invention relates to a method and apparatus for characterizing the tone of the skin or integuments. The apparatus comprises a digital camera or a digital photographic apparatus (12) allowing the capture of at least one digital image (14) of at least one determined skin zone (34, 36, 38, 40), said image being defined by a multiplicity of pixels (N) that is transmitted to a digital image processing device comprising means for splitting the digital image into three color planes: red, green, blue, termed R, G, B; c) means for extracting each of these planes R, G, B; and on each plane, calculation means for logging the grey level value for each of the pixels, i.e. N values, which are optionally processed mathematically by appropriate calculation means, so as to obtain at least one graphical or statistical value and/or at least one value characteristic of the grey levels for each plane, corresponding to a value characteristic of the color of the skin; as well as the luminosity value L; and d) means for characterizing the tone of the skin or integuments on the basis of the combination of the value characteristic of the color of the skin or integuments and of the Luminosity value L. The invention finds an industrial application in a method for assessing the whitening effect of a cosmetic product. |
