1. A method for the calibration of an image pick-up device which is sensitive to magnetic fields, which method includes the following steps: determining calibration data in a plurality of selected positions of the image pick-up device, which calibration data is suitable for distortion correction of an image acquired by the image pick-up device in the relevant position, determining magnetic field data acting on the image pick-up device in the respective selected positions, and associating the magnetic field data with the calibration data in a look-up table.
