Abstract

A method for manipulation of image data for a display screen that can be operated in two operating modes, viz B1 for a free viewing mode and B2 for a restricted viewing mode, comprising: a) switching on the operating mode B2, b) monitoring the eye position of a viewer in a given angular range A, with a signal S being set if the eye position signifies that the viewer is looking at the screen, and being deleted if not looking at the screen, c) manipulating the image data with regard to image parameters, wherein the said manipulation i) is performed to the effect that the quality of the restricted viewing mode B2 is enhanced, ii) is dynamically implemented in a control unit of the display screen, and iii) is performed exclusively while the signal S remains set, and d) repeating steps b) and c) until operating mode B2 concluded.
