Abstract

Verfahren zum Generieren von Videohologrammen für eine holographische Wiedergabeeinrichtung (HAE) mit mindestens einem Lichtmodulatormittel (SLM), in welches eine in Objektpunkte (OP) zerlegte Szene (3D-S) als Gesamthologramm (H∑SLM) kodiert wird und als Rekonstruktion von einem Sichtbarkeitsbereich (VR) aus zu sehen ist, der innerhalb eines Periodizitätsintervalls der Rekonstruierten des Videohologramms liegt, wobei der Sichtbarkeitsbereich (VR) zusammen mit jedem zu rekonstruierenden Objektpunkt (OP) der Szene (3D-S) ein Subhologramm (SH) definiert und das Gesamthologramm (H∑SLM) aus einer Überlagerung von Subhologrammen (SH) gebildet wird, wobei bei einer Sequenz von Bildinhalten für jedes Bild vorrangig die Differenzsubhologramme (SD) von Objektpunkten, die sich bezogen auf die Sichtbarkeit gemäß der Betrachteraugen (VP) in aufeinander folgenden Bildern (Pn-1, Pn) der Sequenz unterscheiden, generiert werden. Die Anzeigevorrichtung (HAE) weist Mittel auf, welche die Videohologramme trotz signifikant verringerter Datenmenge wiederum in hoher Qualität darbieten.
