Hi Martina,
If you have access to Matlab and can recreate the settings on the
camera,
you can use the camera calibration toolbox:
http://www.vision.caltech.edu/bouguetj/calib_doc/
Alternatively, you can use the distortion correction tools in photoshop
(Filter | Distort | Lens Correction...) For an example of
how to do it the photoshop way see:

Good Luck!
