Description

Verfahren zur Wiedergabe farbiger Kinobilder Es ist ein Verfahren für die farbige Kinematographie bekannt, bei dem die Teilbilder auf einem Filmstreifen nacheinander amgeordnet sind und mittels einfies Projektors derart vorgeführt werden, daß jedem Teilbild während seiner Stellung im Bildfenster das betreffende Farbenfilter zugeordnet wird, das gegebenenfalls auch gleich in den Film hineinverlegt werden kann.Process for reproducing color cinema images It is a process known for color cinematography, in which the partial images on a film strip are arranged one after the other and are presented by means of a single projector in such a way that that each sub-picture has the relevant color filter during its position in the picture window is assigned, which can also be placed in the film if necessary can.

Es hat sich nun :gezeigt, daß sich bei diesem Verfahren auf dem Schirmbild unerträgliche Farbenränder ergeben. In der Annahme, :iaß diese Farbenränder lediglich oder in der Hauptsache daher rühren, daß beim Übergang von einer Teilbildergruppe zur nächsten merkliche Ortsveränderungen der Bildeinzelheiten im Gesamtbild vor sich gehen, wurde, um die Farbenränder zu beseitigen oder wesentlich zu vermindern, hinter jeder Teilbildergruppe eine Dunkelpause eingeschaltet. Der praktische Versuch hat gezeigt, daß auch auf diese Weise -die störenden Farbenränder noch nicht zu beseitigen sind.It has now been shown that with this procedure on the screen unbearable color fringes result. On the assumption that: I only had these color borders or mainly due to the fact that the transition from a group of partial images for the next noticeable changes in location of the image details in the overall image going, was to eliminate or significantly reduce the color fringes, A dark pause is switched on behind each group of partial images. The practical experiment has shown that in this way too, the disturbing color fringes are not yet closed are eliminated.

Will man diese zum Verschwinden bringen, dann muß man gemäß der Erfindung dafür sorgen, daß die Teilbilder jeder Bildphasengruppe frei von räumlicher und zeitlicher Parallaxe sind.If you want to make this disappear, then you have to according to the invention ensure that the partial images of each image phase group are free of spatial and are temporal parallax.

Einrichtungen zur Aufnahme von Teilbillern für die Farbenkinematographie, die frei von zeitlicher und räumlicher Parallaxe sind sind an sich bekannt. Das Wesen der Erfindung liegt in der Erkenntnis, daß beim Nacheinanderprojizieren von Teilbildern eines für die Farbenkinematographie bestimmten Filmstreifens einmal, jede Teilbildergruppe von der anderen in an sich bekannter Weise durch eine Dunkelpause getrennt sein muß und daß andererseits unbedingt dafür gesorgt werden muß, daß jede Teilbildergruppe unter sich frei von räumlicher und zeitlicher Parallaxe ist, was an sich ebenfalls bekannt war.Equipment for receiving partial billers for color cinematography, which are free from temporal and spatial parallax are known per se. That The essence of the invention lies in the knowledge that when projecting one after the other from Partial images of a film strip intended for color cinematography once, each group of partial images from the other in a manner known per se through a dark pause must be separate and that, on the other hand, it is imperative to ensure that each Sub-image group free from spatial and temporal parallax is what was also known per se.

Das Verfahren läßt sich sowohl für Zweiwie für Drei- und Mehr farbenfilme anwenden.The process can be used for both two-color and three-color films use.

PATENTANSPRUCH: Verfahren zur Wiedergabe farbiger Kinobilder nach der additiven Methode, bei dem die Teilbilder nacheinander projiziert werden und zur Unterdrückung der beim Übergang von einer Phasengruppe zur nächsten auftretenden Farbränder jedesmal eine Dunkelpause eingeschaltet wird, dadurch gekennzeichnet, daß die Teilbilder jeder Phasengruppe in an sich bekannter Weise frei von zeitlicher und räumlicher Parallaxe sind. PATENT CLAIM: A method for reproducing colored cinema images according to the additive method, in which the partial images are projected one after the other and a dark pause is switched on each time to suppress the color fringes that occur during the transition from one phase group to the next, characterized in that the partial images of each phase group are known per se Way are free from temporal and spatial parallax.
