A method for reducing a mutual influence of pixels of a pixel group having at least one first pixel allocated to a first image and having at least one second pixel adjacent thereto allocated to a second image, the first image being capable of being represented on a viewing direction-dependent display device so as to be recognizable from a first direction of view, and the second image being capable of being represented on the display device so as to be recognizable from a second direction of view differing from the first direction of view, the method having a step of adaptation, using a processing rule, of a first brightness factor of the at least one first pixel and of a second brightness factor of the at least one second pixel in order to reduce the mutual influence.
