An image generating device for an optical, in particular medical tracking system, for determining the position of a recorded image point, includes a light scattering effect generating device, in particular a star and/or cross effect generating device. The invention further provides a tracking system including such an image generating device and to a method for determining the position of a recorded image point using an optical, in particular medical tracking system, in which: an image is generated using an image generating device; a light scattering effect, in particular a star and/or cross effect, is generated on the image for predetermined image points; and in which the position of an image point is ascertained on the basis of the light scattering pattern projected on the image, in particular on the basis of the star and/or cross effect lines and/or their intersection points.
