  • Patent number: 7804597
    Abstract: A method for matching colour properties and texture properties of a repair paint to colour properties and texture properties of a paint film on a substrate to be repaired is provided. In the method, the texture of the paint film is imaged with a digital imaging device, the imaged texture is analyzed using image analysis software, texture data is calculated, and the repair paint is formulated on the basis of the concentrations of paint modules, wherein each paint module is associated to specified texture data and colour data.

  • Patent number: 7027165
    Abstract: Device and method for recording the visual properties of a surface, comprising an imaging device for recording light interaction (reflection or transmission) with a surface, a light source, and a sample area for positioning a sample with a surface to be examined. The imaging device, the light source, and the sample area are arranged in such a way that in one image at least one of the surface properties is recordable as a function of a continuous range of angles between the illumination direction and the observation direction. The imaging device is a CCD camera. The device and method are suitable for imaging and evaluating visual properties which are dependent on the optical geometry, such as flop behavior and gloss.
