A data processor (2) is arranged to process image data according to the measured position of the endoscope and derive updated image data from the processed image data and imae information from the image pick-up apparatus. The processed image data are derived from said image data and said image information from the image pick-up apparatus and said measured position. For example the image data are CT or MRI images or the image data represents one or several anatomical landmarks in the body of a patient (12) to be examined.
