Abstract

For producing stereoscopic image sequences, where image sequences taken in two dimensions are inserted into image sequences taken in three dimensions, it is proposed to convert the image sequences taken in two dimensions into quasi-stereoscopic image sequences. In this conversion, each image sequence taken in two dimensions is duplicated and the second image sequence is displaced in the horizontal direction relative to the first image sequence and relative to the common image frame.

Description

Die heute bei Standbildvorführungen und besonders im Kino und im Fernsehen wiedergegebenen Bildab­ läufe haben für ihren beabsichtigten "Realitäts­ eindruck" den Nachteil, daß die räumliche Tiefe fehlt. Diesem Nachteil kann man dadurch abhelfen, daß man eines der bekannten stereoskopischen Verfah­ ren anwendet, wobei beim heutigen Stand der Technik das Verfahren mit Bildtrennung durch Polarisations­ filter die besten Ergebnisse liefert.The today at still image screenings and especially Images played in the cinema and on TV runs have for their intended "reality impress "the disadvantage that the spatial depth is missing. This disadvantage can be remedied by that one of the known stereoscopic procedures ren applies, with the current state of the art the process with image separation by polarization filter gives the best results.

Insbesondere in der Fernsehtechnik ergeben sich in neuerer Zeit durch neue technische Entwicklungen günstige Realisierungschancen für stereoskopische Systeme. Vor allem das sogenannte "High Definition Television" (HDTV) bietet durch die Verwendung der doppelten Zeilenzahl und höherer Bildbandbreite Möglichkeiten von Kombinationen mit dem stereoskopi­ schen Fernsehen, zum Beispiel dadurch, daß man die beiden stereoskopischen Signale mit der stereoskopi­ schen Links-Rechts-Bildinformation mit üblicher Zeilenzahl und Bandbreite anstelle des hochzeiligen, breitbandigen HDTV-Signals überträgt und wiedergibt. Especially in television technology, in more recently through new technical developments favorable chances of realization for stereoscopic Systems. Especially the so-called "high definition Television "(HDTV) offers through the use of the double the number of lines and higher image bandwidth Possibilities of combinations with the stereoscopic television, for example by watching two stereoscopic signals with the stereoscopic left-right image information with usual Number of lines and bandwidth instead of the high-line, Broadband HDTV signal transmits and plays back.  

Im Rahmen der Untersuchungen und zur Demonstration solcher stereoskopischer Fernsehsysteme wurden geeignete stereoskopische Bildabläufe produziert. Dabei zeigte sich, daß bei dem extrem geringen Be­ stand stereoskopischer Aufnahmen - insbesondere in Fernsehtechnik - zu vielen künstlerischen oder lehr­ haften Themen kein dreidimensional aufgenommenes Bildmaterial zu beschaffen ist. Auch bei der Neupro­ duktion stereoskopischer Bildabläufe ergibt sich ge­ legentlich das Problem, daß wegen der relativen Größe und Kompliziertheit stereoskopischer Aufnahmegeräte praktisch nur zweidimensionale, monoskope Aufnahmen durchgeführt werden können.As part of the investigations and demonstration such stereoscopic television systems suitable stereoscopic image sequences produced. It was found that with the extremely low loading stood stereoscopic recordings - especially in TV technology - too many artistic or teaching topics do not adhere three-dimensionally Image material is to be obtained. Even with the Neupro duction of stereoscopic image sequences results occasionally the problem that because of the relative size and complexity of stereoscopic recording devices practically only two-dimensional, monoscopic images can be carried out.

Fügt man derartige "flache" Bilder in den Ablauf eines stereoskopischen Bildablaufes ein, so wird der Betrachter dies als eine unangenehme Störung empfin­ den, da sein gesamtes psycho-physisches Sehen auf Räumlichkeit eingestellt ist.If you add such "flat" images to the process a stereoscopic image sequence, so the Viewers perceive this as an unpleasant disturbance because his entire psychophysical seeing on Spatiality is set.

Dieses Problem kann erfindungsgemäß in der folgenden Weise gelöst werden: Erfindungsgemäß wird das "flache" Bildmaterial nicht unmittelbar in den Bildablauf ein­ gefügt, sondern vor der Einfügung nach den Prinzipien der an sich bekannten Quasi-Stereoskopie bearbeitet. Dies bedeutet, daß aus den "flachen" Bildabläufen zwei Bildabläufe hergestellt werden, wobei ein Bild­ ablauf gegenüber dem anderen Bildablauf relativ zum gemeinsamen Rahmen in der horizontalen Richtung ver­ schoben ist. Dieses kann zum Beispiel filmtechnisch beim Kopieren und fernsehtechnisch durch zeitliche Verschiebung des Bildsignals erfolgen. Nach den be­ kannten Regeln der Stereoskopie ergibt sich dadurch der Eindruck, daß sich der zweidimensionale Bildab­ lauf in einem von der Verschiebung und ihrer Richtung abhängigen Abstand vor oder hinter dem Bildrahmen befindet. Darüberhinaus erscheint durch verschiedene psychophysische Phänomene, vor allem durch die Sehgewohnheit, der an sich zweidimensionale Bildab­ lauf in sich dreidimensional. Bei vielen Motiven und vor allem bei Bewegungen ist dieser dreidimensionale Eindruck so stark, daß er der echten Stereoskopie erstaunlich nahekommt.This problem can be invented in the following Be solved in a way: According to the invention, the "flat" Images do not directly affect the image flow added, but before insertion according to the principles the known quasi-stereoscopy. This means that from the "flat" picture sequences two image sequences are created, one image sequence compared to the other image flow relative to the common frame in the horizontal direction ver is pushed. This can, for example, in terms of film technology when copying and television technology through temporal The image signal is shifted. After the be Known rules of stereoscopy result from this the impression that the two-dimensional image run in one of the shift and its direction  dependent distance in front of or behind the picture frame located. In addition, appears through various psychophysical phenomena, especially through the Viewing habit, the two-dimensional image run in three dimensions. With many motifs and especially when it comes to movements, this is three-dimensional Impression so strong that it is real stereoscopy comes amazingly close.

Kombiniert man erfindungsgemäß echte stereoskopische Bildabläufe mit zweidimensional aufgenommenen Bild­ abläufen, die in quasi-stereoskopische Bilder umge­ wandelt wurden, so unterstützen sich die beiden Techniken in so überraschender Weise, daß die Bild­ abläufe praktisch als völlig homogen und störungs­ frei empfunden werden. Bei Motiven, die in nur quasi-stereoskopischer Wiedergabe noch "flach" wirken, tritt eine deutliche Raumwirkung auf. Die Wirkung kann noch gesteigert werden, wenn die quasi-stereoskopi­ sche Bildverschiebung jeweils motivgerecht den vor­ ausgehenden und nachfolgenden Szenen angepaßt wird. Dieses kann für eine Szene statisch, aber auch während des Szenenablaufs kontinuierlich geschehen. Gleicher­ maßen werden geeignete Kombinationen echter Stereosko­ pie mit Quasi-Stereoskopie im gleichen Bild zum Bei­ spiel als Vorder- und Hintergrund - was durch bekann­ te Tricktechniken (Masken, Stanzverfahren, "Blue Screen" u. ä.) erreichbar ist - als völlig natürlich empfunden. Da der Beobachter psychophysisch auf Stereobetrachtung eingestellt ist, akzeptiert er die erfindungsgemäß eingefügten Quasi-Stereobilder ohne jede Störung im Empfinden.If one combines real stereoscopic according to the invention Image sequences with two-dimensionally recorded image processes that are converted into quasi-stereoscopic images have been changed, so the two support each other Techniques in such a surprising way that the picture processes practically as completely homogeneous and faulty to be felt freely. With motifs that only in quasi-stereoscopic reproduction still appear "flat", there is a clear spatial effect. The effect can can be increased even more if the quasi-stereoscopic image shift in each case according to the motive outgoing and subsequent scenes is adjusted. This can be static for a scene, but also during of the scene sequence happen continuously. Same thing suitable combinations of real stereosco are measured pie with quasi-stereoscopy in the same picture for the accessory play as foreground and background - what became known te trick techniques (masks, punching processes, "Blue Screen "and the like) is reachable - as completely natural felt. Because the observer is psychophysically on Stereo viewing, he accepts the Quasi-stereo images inserted according to the invention without every disturbance in feeling.

Die Wirkung der erfindungsgemäßen Kombination wurde in zahlreichen Experimenten bestätigt.The effect of the combination according to the invention was confirmed in numerous experiments.
