Abstract (en)

[origin: DE19954029C1] The image enhancement device has the image signal input (1) coupled to 2 different signal paths respectively containing an interpolator (2) and a delay device (3), each providing an image signal with a higher resolution, fed to a switching stage (6) which supplies one or other of the enhanced signals to the display (7), in dependence on a switching control signal (S1). This is provided by a processor (4) coupled to the signal input for evaluating the image content.

Abstract (de)

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. <IMAGE>
