<p>The invention relates to a method and a device for noise reduction in a pulse-width controlled image display device. A monitoring of whether the brightness of several sequential image points is brighter than a given brightness threshold value occurs. If not the case, the delayed but otherwise unchanged input signal is supplied to the display. If, on the other hand, the brightness of several sequential image points is less than the given threshold brightness value, a mean value generation for the brightness values of several sequential image points occurs and said mean value is supplied to the display.</p> |
