Abstract

The invention relates to a method for the two-dimensional perception of stereoscopic images, wherein at least two views A(k) with k>1 of a scene or an object are depicted on an image surface (1) simultaneously and/or in rapid alternation, and only one of the at least two views A(k) are presented to both eyes of at least one observer (3) by means of glasses (2). The invention makes it possible to easily convert to a two-dimensional perceptibility for selected observers (3) in the event of exaggerated 3-D effects in a 3-D cinema or on 3-D screens. The 3-D impression of other observers (3) is not impaired in any way.

Verfahren zur zweidimensionalen Wahrnehmung räumlicher DarstellungenMethod for the two-dimensional perception of spatial representations
Gebiet der Erfindung Die Erfindung bezieht sich auf das Gebiet der räumlichen Darstellung, im speziellen der wahlweisen Unterdrückung des räumlichen Eindruckes.FIELD OF THE INVENTION The invention relates to the field of spatial representation, in particular the optional suppression of the spatial impression.
Stand der Technik Verschiedene 3D-Displaysysteme, insbesondere auf Basis von Brillen sind bekannt und finden gegenwärtig weitere Verbreitung, vor allem im 3D-Kino (IMAX, RealD, Dolby und andere).PRIOR ART Various 3D display systems, in particular based on glasses, are known and are currently being used more widely, especially in 3D cinema (IMAX, RealD, Dolby and others).
Oftmals sind aber 3D-Eindrücke zu groß und der Betrachter erleidet eine Doppelbildwahrnehmung. Wünschenswert wäre daher eine einfache Art der wahlweisen Umschaltung auf 2D, was aber andere Betrachter nicht stören sollte.Often, however, 3D impressions are too big and the viewer suffers a double image perception. It would therefore be desirable to have a simple way of switching to 2D, but this should not disturb other viewers.
Im Stand der Technik bekannt ist diesbezüglich die DE 20015154 U1. Hier wird der 3D- Eindruck bei einem autostereoskopischen Display unterdrückt, indem ein Betrachterauge vermittels einer einseitig abgedunkelten Brille nichts sieht. Dies ist unangenehm und anstrengend, da nicht mehr beide Augen das gleiche Bild sehen.In the prior art is known in this regard DE 20015154 U1. Here, the 3D impression is suppressed in an autostereoscopic display by a viewer eye by means of one-sided darkened glasses see nothing. This is uncomfortable and exhausting, because not both eyes see the same picture.
Beschreibung der ErfindungDescription of the invention
Der Erfindung liegt daher die Aufgabe zugrunde eine Möglichkeit zu schaffen, eine möglichst qualitativ hochwertige zweidimensionale Wahrnehmung räumlicher Darstellungen zu ermög- liehen. Dabei sollen andere Betrachter nicht im Genuss der räumlichen Darstellung beeinträchtigt werden. Diese Aufgabe wird erfindungsgemäß gelöst von einem Verfahren zur zweidimensionalen Wahrnehmung räumlicher Darstellungen, bei welchem auf einer Bildfläche gleichzeitig und/oder in raschem zeitlichen Wechsel mindestens zwei Ansichten A(k) mit k>1 einer Szene oder eines Gegenstandes dargestellt wer- den, mindestens einem Betrachter vermöge einer Brille für beide Augen lediglich eine (d.h. ein- und dieselbe) der mindestens zwei Ansichten A(k) dargeboten wird.The invention is therefore based on the object to create a way to lent the highest possible two-dimensional perception of spatial representations lent. In doing so, other viewers should not be impaired in the enjoyment of the spatial representation. This object is achieved according to the invention by a method for the two-dimensional perception of spatial representations in which at least two views A (k) with k> 1 of a scene or an object are displayed on an image surface simultaneously and / or in rapid temporal change, at least one By means of spectacles, the observer is presented with only one (ie one and the same) of the at least two views A (k) for both eyes.
Mit anderen Worten: Die erfinderische Idee besteht darin, (zumindest zeitweise) beiden Au- gen die gleiche Ansicht einer Stereodarstellung darzubieten, indem die Kanaltrennung entsprechend des verwendeten Verfahrens derart aufgehoben wird, dass beide Augen das gleiche Bild sehen.In other words, the inventive idea is to present (at least temporarily) the same view of a stereo representation to both eyes by canceling the channel separation according to the method used in such a way that both eyes see the same picture.
In einer ersten Ausgestaltung der Erfindung enthält die Brille zwei Polarisationsfilter, bei- spielsweise lineare Polarisationsfilter, die jeweils gleichartig ausgerichtet sind. Eine solche Ausgestaltung ist sinnvoll, wenn auf der Bildfläche linear-polarisationscodierte Stereobildpaare (d.h. eine linke und eine rechte Ansicht) gezeigt werden.In a first embodiment of the invention, the spectacles contain two polarization filters, for example linear polarization filters, which are each aligned identically. Such a design is useful when linear-polarization-coded stereo image pairs (i.e., left and right views) are shown on the image area.
Hier kann es besonders vorteilhaft sein, wenn mindestens einer der Polarisationsfilter in der Brille rotierbar ist, so dass durch Rotation des Polarisationsfilters (um etwa 90 Grad) zwi- sehen einer zweidimensionalen und einer räumlichen Wahrnehmung umgeschaltet werden kann. Dadurch kann jeder Betrachter individuell zwischen einer 2D-Wahrnehmung und einer 3D-Wahrnehmung umschalten.It may be particularly advantageous here if at least one of the polarization filters in the spectacles is rotatable, so that it is possible to switch between a two-dimensional and a spatial perception by rotation of the polarization filter (by approximately 90 degrees). This allows each viewer to individually switch between a 2D perception and a 3D perception.
In einer zweiten Ausgestaltung enthält die Brille zwei Farbfilter, die jeweils im Wesentlichen gleichartig sind. Damit wird insbesondere bei einer Anaglyphendarstellung beiden Augen das gleiche Teilbild, d.h. die gleiche Ansicht A(k), dargeboten.In a second embodiment, the glasses contain two color filters, each of which is substantially similar. Thus, especially in an anaglyph representation, both eyes will be the same field, i. the same view A (k), presented.
Vorteilhaft enthält die Brille zwei austauschbare Farbfilter, so dass durch Austausch der Farbfilter zwischen einer zweidimensionalen und einer räumlichen Wahrnehmung umgeschaltet werden kann, je nachdem ob komplementäre oder identische Farbfilter in der Brille eingesetzt sind.Advantageously, the glasses contain two interchangeable color filters, so that it can be switched by exchanging the color filter between a two-dimensional and a spatial perception, depending on whether complementary or identical color filters are used in the glasses.
Schließlich ist eine dritte Ausgestaltung denkbar, bei welcher die Brille eine Shutterbrille ist, welche in einem 2D-Modus während eines ersten Taktes gleichzeitig beide Shutter öffnet während eines zweiten Taktes gleichzeitig beide Shutter schließt, so das beide Augen stets die gleiche Ansicht A(k) sehen. Entsprechend werden die linken und rechten Bilder im schnellen zeitlichen Wechsel auf der Bildfläche gezeigt.Finally, a third embodiment is conceivable in which the spectacles is a shutter eyeglasses which simultaneously opens both shutters in a 2D mode during a first cycle while simultaneously closing both shutters during a second cycle, so that both eyes always have the same view A (k). see. Accordingly, the left and right images are shown in quick temporal change on the screen.
Der erfinderischer Gedanke lässt sich auch mit anderen Brillensystemen bzw. SD- Darstellungssystemen umsetzen. Für jede der Ausgestaltungen ist es sinnvoll, wenn die Bildfläche ein Flachbildschirm, bevorzugt ein LCD-Bildschirm, eine Projektionsfläche oder ein Röhrenmonitor ist. Andere Ausgestaltungen sind explizit denkbar und im Rahmen der Erfindung inbegriffen.The inventive idea can also be implemented with other glasses systems or SD presentation systems. For each of the embodiments, it makes sense if the image area is a flat screen, preferably an LCD screen, a projection screen or a CRT monitor. Other embodiments are explicitly conceivable and included within the scope of the invention.

Ausführliche Beschreibung der ZeichnungenDetailed description of the drawings
Es zeigt als zunächst die Fig.1 den schematischen Aufbau zur Umsetzung einer Variante des erfindungsgemäßen Verfahrens, bei welchem auf einer Bildfläche 1 gleichzeitig zwei Ansichten A(k) mit k=2 einer Szene oder eines Gegenstandes dargestellt werden, - mindestens einem Betrachter 3 vermöge einer Brille 2 für beide Augen lediglich eine (d.h. ein- und dieselbe) der zwei Ansichten A(k) dargeboten wird. Für alle weiteren Betrachtungen sei hier angemerkt, dass -beispielhaft- die beiden Ansichten A(1 ) und A(2) linear polarisationscodiert dargestellt werden, d.h. beispielsweise ist die linke Ansicht A(1 ) vertikal linear polarisiert und die rechte Ansicht A(2) ist horizontal linear polarisiert.1 shows the schematic structure for implementing a variant of the method according to the invention, in which two views A (k) with k = 2 of a scene or an object are simultaneously displayed on an image area 1, - at least one observer 3 a goggle 2 for both eyes only one (ie one and the same) of the two views A (k) is presented. For all further considerations, it should be noted here that, by way of example, the two views A (1) and A (2) are represented linearly polarization-coded, i. for example, the left view A (1) is vertically linearly polarized and the right view A (2) is horizontally linearly polarized.
Für jede der Ausgestaltungen ist es sinnvoll, wenn die Bildfläche 1 ein Flachbildschirm, bevorzugt ein LCD-Bildschirm, eine Projektionsfläche oder ein Röhrenmonitor ist. Andere Ausgestaltungen sind explizit denkbar und im Rahmen der Erfindung inbegriffen.For each of the embodiments, it makes sense if the image area 1 is a flat screen, preferably an LCD screen, a projection screen or a CRT monitor. Other embodiments are explicitly conceivable and included within the scope of the invention.
Die Fig.2 zeigt eine Brille, die im erfindungsgemäßen Verfahren im Zusammenhang mit einer polarisationscodierten räumlichen Darstellung zum Einsatz kommt. - A -FIG. 2 shows a pair of spectacles used in the method according to the invention in connection with a polarization-coded spatial representation. - A -
In dieser Ausgestaltung der Erfindung enthält die Brille 2 zwei Polarisationsfilter, insbesondere horizontal linear polarisierte Polarisationsfilter, die jeweils gleichartig ausgerichtet sind. Ein Betrachter 3, der eine solche Brille trägt, sieht somit mit beiden Augen in voller Auflösung jeweils das gleiche Bild bzw. die gleiche Ansicht A(k) und erhält einen zweidimensiona- len Eindruck. In dieser Variante würde er beispielsweise die Ansicht A(2), also die rechte Ansicht sehen. Wären die linearen Polarisationsfilter in der Brille 2 vertikal ausgerichtet, so würde er die linke Ansicht A(1 ) sehen.In this embodiment of the invention, the glasses 2 contains two polarizing filters, in particular horizontally linearly polarized polarizing filters, which are each aligned identically. A viewer 3 who wears such spectacles therefore sees the same image or the same view A (k) with both eyes in full resolution and receives a two-dimensional impression. In this variant, for example, he would see the view A (2), ie the right view. If the linear polarizing filters in the goggles 2 were vertically aligned, he would see the left view A (1).
Ganz besondere Vorteile für eine wahlweise 2D- oder 3D-Darstellung erhält man gemäß einer weiteren Ausgestaltung, die in Fig. 3 gezeigt ist. Zu sehen ist hier eine Brille 2, die wahlweise für eine zweidimensionale und eine räumliche Wahrnehmung konfigurierbar ist. Hier ist mindestens einer der Polarisationsfilter in der Brille 2 rotierbar (im Bild der rechts dargestellte), was durch die Strichlinie mit den Drehpfeilen angedeutet ist. Der entsprechende Polarisationsfilter befindet sich hier in einer Zwischenstellung zwischen beiden bevorzug- ten Stellungen für die 2D- und die 3D-Wahrnehmung.Very particular advantages for an optional 2D or 3D representation are obtained according to a further embodiment, which is shown in FIG. You can see here a pair of glasses 2, which is configurable either for a two-dimensional and a spatial perception. Here at least one of the polarization filters in the spectacles 2 is rotatable (in the image of the right), which is indicated by the dashed line with the rotation arrows. The corresponding polarization filter is here in an intermediate position between the two preferred positions for 2D and 3D perception.
Somit kann durch Rotation des Polarisationsfilters (um in der Regel etwa 90 Grad) zwischen einer zweidimensionalen und einer räumlichen Wahrnehmung umgeschaltet werden. Dadurch kann jeder Betrachter 3 individuell zwischen einer 2D-Wahrnehmung und einer SD- Wahrnehmung umschalten, obwohl alle Betrachter 3 die gleiche Bildfläche 1 betrachten.Thus, by rotation of the polarizing filter (usually about 90 degrees), a switch between a two-dimensional and a spatial perception. As a result, each viewer 3 can individually switch between a 2D perception and an SD perception, although all viewers 3 view the same image area 1.
Die Vorteile der Erfindung sind vielseitig. Vermöge der Erfindung ist es möglich, etwa bei übertriebenen 3D-Effekten im 3D-Kino für ausgewählte Personen einfach auf eine zweidimensionale Wahrnehmbarkeit umzuschalten. Der Eindruck anderer Personen wird keineswegs beeinträchtigt. Zudem kann die Erfindung mit einfachen Mitteln realisiert werden. The advantages of the invention are versatile. By virtue of the invention, it is possible to easily switch to a two-dimensional perceptibility for exaggerated 3D effects in 3D cinema for selected persons. The impression of other people is not impaired. In addition, the invention can be realized by simple means.
