Description
Verfahren zur Erzeugung farbiger Projektionsbilder vermittels eines als Bildfläche dienenden vergrößerten Farbrasters Es ist versucht worden, durch Projektion eines mit einem beliebigen Farbraster vorbehandelten Positivfilms auf einen vergrößerten farbigen Raster die Tiefenwirkung des Bildes zu erhöhen, jedoch kann auf diesem Wege keine farbige Vergrößerung erzielt werden, weil keirxe dem Objekt entsprechende Farbaufnahme stattfindet.Method for generating colored projection images by means of a Enlarged color raster serving as a picture surface It has been attempted by Projection of a positive film pretreated with any color grid an enlarged colored grid to increase the depth of the image, however no colored enlargement can be achieved in this way, because this is not possible Object corresponding color recording takes place.
Die Erfindung betrifft ein Verfahren zur Erzeugung farbiger Projektionsbilder vermittels eines als Bildfläche dienenden vergrößerten Farbrasters, bei welchem in der Weise gearbeitet wird, daß zur Projektion ein hinter einem entsprechenden Aufnahmefarbraster aufgenommenes Negativ bzw. ein von diesem gewonnenes Diapositiv dient.The invention relates to a method for generating colored projection images by means of an enlarged color grid serving as an image area, in which It is worked in such a way that for projection one behind a corresponding one Recording color grid recorded negative or a slide obtained from this serves.
Auf diese Weise erhält der Großfarbraster die Farbwerte in genauer Übereinstimmung mit den Farben des Objektes, so daß ein naturgetreues, farbrichtiges Projektionsbild erzielt wird.In this way, the large color raster receives the color values more precisely Correspondence with the colors of the object, so that a lifelike, color-correct one Projection image is achieved.
Der Großfarbraster kann von vornherein auf der Bildfläche sich befinden, so z. B. in bekannter Weise aufgemalt oder als Schablone (fest oder abnehmbar) angeordnet sein. Das die Farbwerte enthaltende Diapositiv wird dann auf diesen Raster in einer mit diesem übereinstimmenden Vergrößerung projiziert, so daß das Bild farbig erscheint.The large color raster can be on the picture surface from the start, so z. B. painted on in a known manner or arranged as a template (fixed or removable) be. The slide containing the color values is then on this grid in a projected with this corresponding magnification, so that the image appears in color.
Das Verfahren bringt den Vorteil mit sich, daß durch Änderung des Projektionsverhältnisses beim Diapositiv oder beim Raster oder bei beiden eine genaue Übereinstimmung oder Deckung zwischen den beiden Teilen auf einfache Weise durch Verstellen der Projektionslinsen, sogar während der Projektion, zu erreichen ist. Diese Anpassungsfähigkeit gestattet, daß z. B. ein Raster für mehrere hinter unterschiedlichen Farbrastern aufgenommene Diapositive verwendbar ist.The method has the advantage that by changing the Projection ratio in the case of a slide or a grid or both an exact one Match or congruence between the two parts in a simple manner Adjusting the projection lenses, even during projection, can be achieved. This adaptability allows z. B. a grid for several behind different Color grids recorded slides is usable.
