Claim 16:
17. A device for determining the reflectance behavior of a surface of an object, wherein the device comprises a control unit and a detection unit, wherein the detection unit is configured to record a plurality of images of the object, which differ in terms of a recording direction and/or an illumination direction during the recording, and wherein the control unit is configured to create data sets with entries which each describe a reflectance value derived from the images and an assigned recording direction and an assigned illumination direction, with each data set being assigned to a point on the surface of the object, wherein
the control unit is configured to determine missing entries in the data sets on the basis of entries of already created data sets,
wherein
the control unit for determining the missing entries in the data sets is also configured to take into account a measure of similarity to the reflectance values derived from the images, perform a mean value calculation or a weighted mean value calculation for the reflectance values derived from the images, or perform a smoothing of the reflectance values derived from the images.
