Abstract
Description
Das folgende Verfahren soll es ermöglichen, dreidimensionale Farbbilder auf einem Monitor oder entsprechenden Betrachtungsgeräten darzustellen.The following procedure should enable three-dimensional color images on a Display monitor or corresponding viewing devices.
Die Projektionsebene des Betrachtungsgerätes (Mattscheibe) ist so aufgebaut, daß die Betrachtungsseite auf der Oberfläche Rillen besitzt, die einen linsen- oder prismenförmigen Querschnitt aufweisen (Fig. 1). Diese Rillen verlaufen beim Monitor senkrecht von oben nach unten.The projection plane of the viewing device (focusing screen) is constructed in such a way that the viewing side has grooves on the surface which have a lenticular or prism-shaped cross section ( FIG. 1). These grooves run vertically from top to bottom on the monitor.
Durch die Linsen- oder Prismenoberfläche auf der Projektionsmattscheibe können bestimmte Bildpunkte nur von einem bestimmten Betrachtungswinkel aus gesehen werden. Durch geschickte Wahl der Bildpixel können für die beiden Augen des Betrachters unterschiedliche Ansichten eines Bildes erzeugt werden, wodurch letztlich ein dreidimensionaler Eindruck entsteht.Through the lens or prism surface on the projection screen certain pixels only seen from a certain viewing angle become. By skilfully choosing the image pixels for the two eyes of the Different views of an image are generated, ultimately resulting in a viewer three-dimensional impression is created.
Die Projektionsmattscheibe darf aber eine gewisse Dicke nicht überschreiten, da ansonsten die Bildpunkte durch Parallaxe auf der Betrachterseite falsch abgebildet werden.However, the projection screen must not exceed a certain thickness because otherwise the pixels are incorrectly imaged by parallax on the viewer side become.
Da eine dünne Mattscheibe dem von außen auf die Bildröhre wirkenden Luftdruck nicht standhalten würde, ist eine technische Umsetzung z. B. folgendermaßen zu realisieren:Because a thin screen does not affect the air pressure acting on the picture tube from the outside would withstand is a technical implementation z. B. to implement as follows:
Die Projektionsmattscheibe wird direkt von innen vor die Betrachtungsfläche der Bildröhre angebracht (Fig. 2, Fig. 3). Sie kann beispielsweise aus elastischem Kunststoff gefertigt werden, wodurch eine gute Anlage gewährleistet wird.The projection screen is attached directly from the inside in front of the viewing area of the picture tube ( Fig. 2, Fig. 3). For example, it can be made of elastic plastic, which ensures a good system.
Weiterhin ist es auch denkbar, daß eine solche Projektionsmattscheibe vor einem Betrachtungsgerät angebracht wird. Die entsprechende Abbildungsschärfe kann dann durch eine Optik erfolgen (Fig. 4). Hierdurch ist es auch möglich, das Monitorbild auf eine kleinere Fläche zu projizieren, wodurch ein geringerer Pixelabstand entsteht.Furthermore, it is also conceivable that such a projection screen is attached in front of a viewing device. The corresponding image sharpness can then be achieved using optics ( FIG. 4). This also makes it possible to project the monitor image onto a smaller area, which results in a smaller pixel spacing.
