摘要： A method for inspecting lacquered surfaces is provided, wherein radiation being irradiated by a first radiation device onto a surface to be inspected at a first predetermined irradiation angle, and a color image recording device recording a spatially resolved image of the surface irradiated by the irradiation direction at a first observation angle, this image recording device having a first predetermined sensitivity dependent on a wavelength of the radiation impinging on the image recording device, wherein an image evaluation device carries out a section-by-section and desirably pixel-by-pixel evaluation of the image recorded by the image recording device.
