Abstract
The invention is directed to an arrangement for determining the pupil center of an eye of a person in an image. The arrangement includes a touch-sensitive display device for displaying the image with the eye of the person and a gesture recognition unit for recognizing a first predetermined gesture in response to a touching of the touch-sensitive display device by a user. The gesture recognition unit is configured to recognize, as a first predetermined gesture, a movement of two fingers at a distance (D) to each other touching the touch-sensitive display and carrying out an orbital rotational movement about a common rotation center. A contrast changing unit changes the contrast of the image displayed on the touch-sensitive display device in response to the user touching the touch-sensitive display device in a manner recognized as the first predetermined gesture by the gesture recognition unit.
