In an image processing method (18), for images (9) in a image sequence (8), in each case a position indication (23) of a center (24) of the image content (10) of individual images (9) is calculated in a completely computer-implemented and/or hardware-implemented, statistical evaluation method (20). The center (24) is defined by a circle section (62) which is described or characterized by a separation line (12) between the image content (10) and a periphery (11) which is supplementary to the image content (10) in the image (9) or complementary therewith.
