Abstract

A color value for an optical fiber of a fiberscope can be generated on the basis of the intensity values of a plurality of sensor elements of a sensor element arrangement that are sensitive to one spectral region each from a set of sensor spectral regions, if calibration values are provided for each of the spectral regions associated with the optical fiber. The intensity values of all sensor elements of the respective spectral region that are illuminated by the light guide can be combined with the provided calibration values, in order to obtain the color value associated with the optical fiber, which reproduces the color of the light transported by the optical fiber.
