Abstract

Für die Interpolation von Abtastwerten für eine bewegungskompensierende Prädiktion von Bildern einer Bewegtbildfolge wird eine Interpolationsfiltereinrichtung (IF) verwendet, deren Filterfunktion örtlich und/oder zeitlich für eine einem Verschiebungsvektor zugeordneten Bereich von Abtastwerten eines Bildes variabel einstellbar ausgebildet ist.
