PCT No. PCT/DE92/00007 Sec. 371 Date Jul. 27, 1993 Sec. 102(e) Date Jul. 27, 1993 PCT Filed Jan. 7, 1992 PCT Pub. No. WO92/14340 PCT Pub. Date Aug. 20, 1992.A method for correcting the gaze direction of persons in a digital image where an angular error between the gaze direction and the camera axis is determined. The pupils of both eyes in the image are then segmented and displaced within the image plane. Areas which have become free are filled in using the color of the eyeball. Any interfering edges produced are attenuated in a subsequent processing step (e.g., by using a low-pass filter). The method is also applicable for a sequence of images over time.
