  • Method and device for reducing a mutual influence of pixels of a pixel group
    Patent number: 9311891
    Abstract: 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.

  • Test device, display device, and method for checking a validity of display signals
    Patent number: 8543349
    Abstract: A test device for checking the validity of display signals pertaining to a predefined image includes a device for ascertaining image data from the display signals, device for determining a test value of the image data, and a comparator unit for comparing the ascertained test value with a stored test value pertaining to the image, a validity of the display signals being established in the case where the two test values coincide.
