Abstract

Az eljárás tárgya kép-interpolációs rendszer, amely képet alkotóvonalak közötti rések interpolálásához használható. A rendszertartalmaz virtuális interpolációs adatgeneráló eszközt (100,120) abemeneti kép vonalai közötti köztes vonalak virtuális interpolációsadatának generálásához a bemenetiképvonal-adat alapján, valamintinterpoláló eszközt bemeneti kép vonala közötti pixelekinterpolálásához a generált virtuális interpolációs adat alapján.
