Abstract

Verfahren zum Wiedergeben der Bildsignalwerte (R, G, B) der Bildpunkte einer Bildpunktfolge auf einem Sichtgerät (18) mittels digitaler Bildsteuersignale der Wortlänge M Bit über digitale Ansteuersignale der kürzeren Wortlänge N Bit. Gemäß dem Verfahren kann das digitale Ansteuersignal für einen Bildpunkt entweder seinem Bildsignalwert (R, G, B) oder einem Änderungswert (IR) gegenüber dem Bildsignalwert (R, G, B) des vorhergehenden Bildpunktes entsprechen.
