Zusammenfassung:	The present invention relates to a method for calibrating a camera including an image sensor having a centre position. The method comprising: capturing an image view projected onto the image sensor by a lens, said projected image view having a centre, detecting at least one image view boundary of the image view captured by the image sensor, determining, in at least one dimension, a projection centre position corresponding to the centre of the projected image view on the image sensor based on detected boundary, determining offset between said projection centre position and a sensor centre position, defined in at least one dimension, corresponding to the centre of the image sensor capturing the projected image view, and moving the image sensor in relation to said lens based on said offset in order to arrive at a substantially zero offset in at least one dimension between the centre of image sensor and the centre of the projected image view.
