Die Erfindung bezieht sich auf ein Verfahren zur Unterbindung von Bildverzerrungen, die bei der Überlagerung von stereoskopischen Teilbildern auftreten können, die voneinander getrennt und aufeinander wiederzugeben sind.The invention relates to a method for preventing image distortion, which can occur when stereoscopic partial images are superimposed on one another are to be reproduced separately and on top of each other. Zur Veranschaulichung der bei der Wiedergabe solcher Teilbilder entstehenden Bildverzerrungen dienen die Abb. 1 bis 3. Gemäß Abb. ι werden die stereoskopischen Teilbilder ι und 2 auf dem Projektionsschirm 3 mittels des Objektivs 4 an den Stellen ι" und 2a abgebildet. Werden, nun in den Strahlengang lichtablenkende Mittel zur . Ver-einigung der beiden Teilbilder eingeschaltet, so werden die Bilder ia und 20 einander überlagert. Dies zeigt die Abb. 2, nach der die Teilbilder ia und ia durch die Prismenkeile 5 auf dem Projektionsschirm 3 zur Überlagerung gebracht werden. Durch die Versetzung der Bilder wird aber z. B. der Strahl 6 (Abb. 1) des Teilbildes 1, ia, dessen neue Lage nach der Versetzung mit 6a (Abb. 2) bezeichnet ist, verkürzt, während der Strahl 7 (Abb. 1), der nach ya (Abb. 2) verlagert wird, verlängert wird. Dies bedeutet aber, daß das ursprünglich rechteckige Bild trapezförmig verzerrt wird, und zwar gilt dies ebenso für das Teilbild 2. Die beiden projizierten Teilbilder würden also entsprechend der Abb. 3 zur Deckung kommen.To illustrate generated during the reproduction of such partial images image distortion fig. 1 are used to 3. According to Fig. Ι the stereoscopic partial images are ι and 2 ι on the projection screen 3 by means of the lens 4 at the points "and ready to 2 a., Will now be in the beam path of light deflecting means. of the two partial images Ver-agreement is turned on, the images are I A and 2 0 superimposed on each other. This is shown in Fig. 2, after the partial images i a and i a by the wedge prisms 5 on the projection screen 3. The offset of the images, however, shortens beam 6 (Fig. 1) of partial image 1, i a , whose new position after the offset is denoted by 6 a (Fig. 2) , while the beam 7 (Fig. 1), which is shifted to y a (Fig. 2), is lengthened, but this means that the originally rectangular image is distorted in a trapezoidal shape, and this also applies to partial image 2. The both projected part images would therefore be congruent according to Fig. 3. Die Erfindung bezweckt nun die Unterbindung der dargestellten Bildverzerrungen und besteht darin, daß die Teilbilder beim Kopieren derart verzerrt werden, daß die bei der Wiedergabe durch die Überlagerung der Bilder auftretenden Bildverzerrungen ausgeglichen sind.The invention now aims to prevent the displayed image distortions and consists in the fact that the partial images are so distorted during copying that the at the playback compensated for image distortions caused by the superimposition of the images are. Die Verzerrung beim Kopieren kann z. B. in einfacher Weise dadurch bewirkt werden, daß das Negativbild unter Verwendung einer optischen Einrichtung mit großer Tiefenschärfe auf den Positivfilm, dessen Ebene in einem Winkel zur optischen Achse der optischen Einrichtung steht, abgebildet wird.The distortion in copying can e.g. B. can be effected in a simple manner by that the negative image using an optical device with a large depth of field on the positive film, the plane of which is at an angle to the optical axis of the optical device is displayed. PatentακSPRUch:Patent APPLICATION: Verfahren zur Unterbindung von Bildverzerrungen bei aufeinander wiederzugebenden, voneinander getrennten stereoskopischen Teilbildern, dadurch gekennzeichnet, daß die Teilbilder beim Kopieren derart verzerrt werden, daß die bei der Wiedergabe durch die Überlagerung der Bilder auftretenden Bildverzerrungen ausgeglichen sind.Method for preventing image distortion in the case of separate stereoscopic partial images to be reproduced on top of one another, characterized in that that the partial images are distorted during copying in such a way that the during reproduction by the superimposition of the Distortions occurring in images are compensated for.
