Abstract: An instrument and related process for measuring color, shade, gloss, shape and/or translucence of a tooth. First, the instrument uses searchlight illumination to illuminate a tooth with constant irradiance. Second, the instrument uses colorimetric imaging to collect time-separated frames of different wavelengths of light reflected from a tooth and to combine those frames into a color image. Third, the instrument includes a sanitary shield to establish a reference color and a predetermined distance to a target tooth. Fourth, the instrument provides line-of-sight viewing so an operator may simultaneously view a display of the image on the instrument and the object being measured. Fifth, the instrument is impervious to pollutants because it incorporates a sealed measurement window. Sixth, optical measurements of a tooth taken by a dentist are compared to optical measurements of a prosthetic restoration for that tooth to confirm satisfactory matching of optical characteristics of the tooth and restoration.

Abstract: An output current from each pixel sensor can be extracted at an arbitrary ratio by a current divider. An arithmetic control unit sets the dividing ratio in correspondence to a color matching function. The current components are added together by a summing amplifier so that a signal corresponding to a tristimulus value is composed and then converted into a digital signal. That is, weighting by weight factors corresponding to color matching functions of CIE 2-degree observer is performed in a stage of analog signal processing.

Abstract: A graphical image scanner scans pixelated regions of a color image to measure light intensities in a plurality of hyperspectral bandpasses for each pixel. The scanner transforms the hyperspectral bandpass intensities into device-independent color representations for each pixel, using scientific color representations, for example, as defined in CIE-31 and CIE-76 colorimetry standards as devised by the Commission Internatonale de l'Eclairage (CIE).

Abstract: A method of producing a finish for a selected wood substrate, wherein the finish provides the selected wood substrate with a color that matches the color of a target object. In accordance with the method, calculations are performed to determine the quantities of at least one group of colorants required to produce a semitransparent wood stain from a vehicle, wherein when the semitransparent wood stain is applied to the selected wood substrate, the selected wood substrate will have a color that matches the target object. The calculations are performed using reflectance measurements of the target object obtained using a spectrophotometer and previously obtained spectral data of the colorants as applied to at least one type of wood. The colorants used to form the semitransparent wood stain do not include a white colorant.

Abstract: Methods and systems for measuring with a Color Measurement System of predetermined specification and evaluating the color of skin, teeth, hair and material substances with a Color Index. The principles of this invention also relate to techniques for using such a Color Measurement System with the Color Index in medical applications such as the detection of chromogenic disease including bilirubin infant jaundice, cosmetics applications and in the evaluation of the color of hair or teeth, and other applications. The Color Index is measured and calculated from the reflectance spectrum of any skin (or teeth, hair or material substance) by a two step process. The first step is the weighting of the visible spectra with a unique set of weighting factors which calculate a sample's reflectance spectrum's contribution to the appearance of four color components independent of the illuminating condition. The second step places the sample's reflectance spectrum's contribution to the appearance of the four color components in opponency to each other and calculates the Color Index providing attributes representative of correlates of lightness-darkness (L, also referred to as lightness), redness-greenness (M) and yellowness-blueness (N).
