Patentiert im Deutschen Reiche vom 8. November 1913 ab.Patented in the German Empire on November 8, 1913.
Die Erfindung, betrifft eine Abänderung des bekannten zur Herstellung von stereoskopisch wirkenden Durchsichtsbildern benutzbaren Ivesschen Verfahrens der Parallax-Stereoskopie, wodurch es möglich ist, die Bilder mit scharfer stereoskopischer Wirkung in Aufsicht zu betrachten. The invention relates to a modification of the known for the production of stereoscopic effective transparency images usable Ivess method of parallax stereoscopy, whereby it is possible to view the images with a sharp stereoscopic effect from above.
Nach dem Ivesschen Verfahren werden Durchsichtsbilder in der Weise erzeugt, daßTransparency images are produced according to Ivess's method in such a way that
ίο die beiden stereoskopischen Teilbilder in Streifen zerlegt und auf einer Platte so ineinandergelegt werden, daß je einem Streifen des einen Teilbildes ein Streifen des anderen Teilbildes folgt. Über dieses so gewonnene Streifenbild wird in einiger Entfernung davon ein Raster derart angeordnet, daß die Rasterstreifen für das rechte Auge die Streifen des linken Teilbildes decken, so daß nur die Streifen des rechten Teilbildes sichtbar werden, und daß ebenso die Rasterstreifen für das linke Auge die Streifen des rechten Teilbildes decken, so daß nur die Streifen des linken Teilbildes sichtbar sind.ίο the two stereoscopic partial images in Strips are disassembled and placed one inside the other on a plate in such a way that one strip each a strip of the other partial image follows. About this so won Stripe image a grid is arranged at some distance therefrom in such a way that the grid stripes cover the stripes of the left partial image for the right eye so that only the stripes of the right partial image are visible, and that the grid stripes for the left eye also cover the stripes of the right partial image, so that only the stripes of the left partial image are visible.
Dieses Verfahren gestattet aber nur die Herstellung von einwandfreien Durchsichtsbildern, wogegen nach vorliegender Erfindung brauchbare Aufsichtsbilder herstellbar sind. Wird nach dem Ivesschen Verfahren versucht, Aufsichtsbilder zu schaffen, auf die Rigl in der Photogr. Korrespondenz 1907, S. 411, ver-35 However, this method only allows the production of flawless transparent images, whereas, according to the present invention, usable reflective images can be produced. If the Ivess method is used to try to create reflective images on the rigl in the photogr. Correspondence 1907, p. 411, verse 35
weist, so treten bei denselben, auch bei richtiger Position der Augen des Beschauers, vor dem Bilde störende Nebenlinien oder Doppelkonturen auf, welche das Bild verworren und unscharf erscheinen lassen.shows, they appear even if the beholder's eyes are in the correct position the picture on disturbing secondary lines or double contours, which confuse the picture and appear fuzzy.
Das den Gegenstand der Erfindung bildende, diese Nachteile behebende Verfahren besteht im Wesen darin, daß einerseits ein dunkler Bildgrund bzw. ein mit dem Raster gleichfarbiger Bildgrund gewählt wird, auf welchem ein helleres, z. B. ein weißes oder ausgebleichtes Negativ, das in der bei der Parallax-Stereoskopie üblichen Weise aus den beiden Teilbildern zusammengesetzt ist, erzeugt wird. Dadurch entsteht ein korrektes scharfes Aufsichtsbild mit vollendeter stereoskopischer Wirkung.The method which forms the subject of the invention and which overcomes these disadvantages consists essentially in the fact that on the one hand a dark background or one of the same color as the grid Image ground is chosen on which a lighter, z. B. a white or bleached one Negative, the result of the two in the usual way in parallax stereoscopy Sub-images is composed, is generated. This creates a correct, sharp image with a perfect stereoscopic image Effect.
