Abstract: The invention relates to a device for measuring colour, lustre and undulations on lacquered freeform surfaces at a predetermined target distance and symmetrically in relation to the measuring point normal lines at a measuring point. Said device is characterised by the provision of a measuring head that can be displaced in three dimensions by at least one motor and that comprises a measuring-head axis, a light emitter and a video camera. The light emitter is provided with a planar light pattern that is to be emitted along its illumination axis. An evaluation unit is provided for the light pattern (reproduction pattern) of the light emitter that is reproduced in the video camera, said evaluation unit emitting a control signal which is dependent on and formed from the distortion produced or the migration of the reproduction pattern. The measuring head is provided with a motor control, to whose input the control signal of the evaluation unit is applied and the measuring head is displaced in order to reduce the distortion or the migration of the reproduction pattern in the video camera to below a predetermined value, in such a way that both the measuring head axis coincides with the measuring point normal lines and the vertex of the angle formed by the illumination axis of the light emitter and the optical axis of the video camera coincides with the measuring point.

Abstract: A method and apparatus for color matching are provided, in which paint recipe neural networks are utilized. The color of a standard is expressed as color values. The neural network includes an input layer having nodes for receiving input data related to paint bases. Weighted connections connect to the nodes of the input layer and have coefficients for weighting the input data. An output layer having nodes are either directly or indirectly connected to the weighted connections and generates output data related to color values. The data to the input layer and the data from the output layer are interrelated through the neural network's nonlinear relationship.

Abstract: An illuminance spectrum I of reflected light from a color print of an N-order color having an arbitrary dot percent d 1-N is defined by a diffuse reflection coefficient Sb(d 1-N ,λ) and a specular reflection coefficient Ss(d 1-N ,λ). These reflection coefficients are obtained in the following manner. A plurality of reference colors are specified on each of Nx2 (N-1) sides that constitute an N-dimensional color space including the N-order target color. Each reflection coefficient is expressed by a linear combination of a plurality of reference reflection coefficients Sb and Ss, which are set in advance for the plurality of reference colors. The illuminance spectrum of reflected light is then determined according to these reflection coefficients Sb and Ss. Color data representing the colors of the print in a colorimetric system suitable for an output device are subsequently generated from the illuminance spectrum.

Abstract: The invention relates to evaluation of gemstones and other transparent specimens and in particular to color grading of gemstones. The device utilizes a band pass filter (23) which transmits light through lenses (32) onto the detector array (31) to obtain the spectral response of a complete image. The gemstone is illuminated with annular light ring (22), which receives light from a light source (18) located in the right half compartment (14), in a way that provides for analysis of both reflected and transmitted light. The device utilizes multiple lighting angles to construct a composite image that is used to perform the grading of the gemstones.

Abstract: A portable colorimeter for characterizing the optical properties of a colored surface and in particular a colored surface containing metallic or pearlescent particles, which employs three multiangular spectrophotometric measurements to derive color constants for the surface. The colorimeter is a compact integrated unit housing irradiation, detection, control, analysis and display means and employs three illumination angles, preferably -30°, O°, and 65°, and one detection angle, preferably 45°, all measured from the sample normal. The method includes determining the tristimulus values of the color of the sample surface from low resolution spectral reflectance data preferably using twelve detector elements.
