Abstract
A method for correcting the parcentricity in zoom systems. The positional difference in the image between at least two different zoom positions is detected in order to explicitly or implicitly determine the position in the image which remains stationary during zooming. The travel lengths of a means for positioning the object in the object plane required for correcting the zoom-dependent parcentricity error are calculated and provided as control variable for the appropriate positioning of the means for positioning the object in the object plane, such that the target position appears stationary in the image after or during zooming.
