发明名称 Method and device for determining the colour of a translucent object, such as a tooth.
摘要 <p>The invention relates to a method and a device for determining the colour of a translucent object, such as a tooth, by a measurement (10) of the reflectance of this object at wavelengths essentially corresponding to the maxima in sensitivity of the human eye in hue and in saturation, by a calculation (12) of the white luminance included in the luminance of the object illuminated by a given standard illuminant, by calculation (14) of a saturation percentage of the colour of the object seen by the human eye, and by determinations (16, 18) of the pigmentations of this colour compared to white. &lt;IMAGE&gt;</p>
