    Abstract: By inputting a predetermined number of first data to a color reproducing device, a predetermined number of reproduced colors are respectively measured, and a plurality of relationships of correspondence between inputted first data and measured second data are determined. On the basis of the plurality of relationships of correspondence between the first data and the second data, relationships of interpolated correspondence, which express relationships between second data other than the measured second data and first data corresponding to the second data other than the measured second data, are estimated. After second data which is the same as or closest to a color to be reproduced is selected, first data corresponding to selected second data is selected on the basis of the relationships of correspondence and the relationships of interpolated correspondence. Selected first data is then inputted to the color reproducing device, and a color to be reproduced is reproduced.

    Abstract: Described herein is a method for generating a bi-directional texture function (BTF) of an object, the method including at least the following steps:



    measuring an initial BTF for the object using a camera-based measurement device,
    capturing spectral reflectance data for the object for a pre-given number of different measurement geometries using a spectrophotometer, and
    adapting the initial BTF to the captured spectral reflectance data), thus, gaining an optimized BTF.




    Also described herein are respective systems for generating a bi-directional texture function of an object.

    Abstract: A device for radiometrically gauging the surface of a measurement object (O) includes: at least one measurement array featuring an illumination array and a pick-up array; and a processor (P) for controlling the illumination array and the pick-up array and for processing measurement signals produced by the pick-up array and for providing processed image data. The illumination array exposes a region of the measurement object (O) to illumination light at an illumination angle (θi) and an illumination aperture angle (αi), and the pick-up array captures measurement light, reflected by the measurement object (O), at a pick-up angle (θv) and a pick-up aperture angle (αv) and guides it onto an image sensor exhibiting a pixel structure. The measurement object (O) is gauged multispectrally in multiple wavelength ranges, wherein the image sensor produces multispectral image data. Angular and spatial conditions are indicated which optimise the measurement device (MD) with regard to characterising sparkles.
