Abstract
In order to correct for fixed pattern noise in the signals of an image sensor, image signal values are read out from the pixels of the sensor. Individual correction values are added as analogue quantities to the image signal values via a signal path having a defined transfer function. Parameters which are characteristic of the defined transfer function are provided in a memory and the individual correction values are calculated in a correction value calculating unit using the parameters provided.
