Vector based Up-Conversion
Frame rate conversion without motion judder or double contour effectsrequires motion estimation between two successive fields
and to shift pixels depending on the measured motion.

Erkanntes Objekt löst Blink-Zyklus aus
Bewegtes Objekt
-> Kein Helligkeitsverlust, da Blinkdauer von der eingestellten Helligkeit abhängt
