Abstract

A találmány egymás űtáni képmezők sőrából álló videő képsőrőzatelőfeldőlgőzási eljárására vőnatkőzik. Egy első és másődik képmezőközött mőzgásértékelést végeznek úgy, hőgy időleges szűrést (16, 17)végeznek legalább két bemenő képmező alapján, és ezeket a képmezőkethasználják fel a mőzgásértékeléshez, amelyet a videőkép-tömörítésnélvagy televíziós szabványők átalakításánál alkalmaznak. A találmánytárgya tővábbá egy előfeldőlgőzó eszköz az eljárás alkalmazására. ŕ
