Abstract

Die Erfindung betrifft eine Vorrichtung zur Verbesserung der Bilddarstellung auf einem Display. Ein eingangsseitig vorhandenes Bildsignal einer ersten Auflösung wird entweder unter Verwendung eines Interpolators oder einer Verzögerungsschaltung in ein Bildsignal einer zweiten, höheren Auflösung umgesetzt, welches auf dem höher auflösenden Display dargestellt wird. Die Steuerung des Schalters geschieht unter Verwendung einer Recheneinheit, die das Eingangssignal analysiert und zur Ermittlung des Schaltersteuersignals auch Gebrauch von der Signalhistorie macht.
