Abstract
Farbteiler-Bildwandler-Gruppe, insbesondere für Fernsehkamera und/oder digitale Fotokamera, dadurch gekennzeichnet, dass sie sowohl ein schräg zum Lichtbündel stehender teildurchlässiger Spiegel, als auch die Mosaikfarbfilter enthält.Color splitter / image converter group, in particular for television cameras and / or digital photo cameras, characterized in that it contains both a partially transparent mirror positioned at an angle to the light beam and the mosaic color filter.
Description
Die Farben in den Fernseh- und digitalen Fotokameras werden bisher entweder durch Farbteilerprisma oder Mosaikfarbfilter geteilt. Die neue Gruppe soll die Verbesserung der Bildqualität auf dem Wege der Anpassung der Bildverarbeitung durch Bildwandler und Farbteiler bis zum Objektiv an einander und die Beseitigung der störenden Moire ermöglichen.The colors in the television and digital still cameras are shared by either color splitting prism or mosaic color filters. The new group aims to improve the image quality by adapting the image processing by image converter and color divider to the lens to each other and the removal of the disturbing Moire.
Das Lichtbündel wird durch teildurchlässige Spiegel in mehrere Bündel geteilt. Die Bündel werden durch die Mosaikfarbfilter farbgeteilt und von den Bildwandlern empfangen. Die Zeichnung (3) stellt eine Variante dar (mit „
Die Gruppe eignet sich für die Farbbildaufnahmegeräte, insbesondere für digitale Fernseh- und Fotokameras.The group is suitable for color image recording devices, especially for digital television and photo cameras.
Moderne Farbfernseh- und digitale Fotokameras beinhalten Objektiv, Zoom, Fokussierung, Verschluss, Belichtungsprogramme, optischen oder elektronischen Bildstabilisator, Farbteiler und Bildwandler, Prozessor, Arbeitsspeicher und Software für die Bildbearbeitung und Weisausgleich, optischen und/oder elektronischen Sucher, Mikrophone, Speicher, Stromversorgung, Anschlüsse usw.Modern color television and digital still cameras include lens, zoom, focus, shutter, exposure programs, optical or electronic image stabilizer, color splitters and imagers, processor, memory and software for image processing and white balance, optical and / or electronic viewfinder, microphones, memory, power supply, Connections etc.
Die Hauptelemente der Kamera sollen genau an einander angepasst und abgestimmt sein, um qualitativ hochwertige Bilder liefern zu können. Es haben sich Fernsehkameras mit drei Bildwandlern und Farbteilerprisma (
Eigentliches Hauptziel der Erfindung ist, die Voraussetzungen für die Verbesserung der Qualität der Bilder auf dem Wege der Anpassung der Hauptelemente der Kamera an einander zu schaffen.The main object of the invention is to create the conditions for improving the quality of the images by adapting the main elements of the camera to each other.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die Farbteiler-Bildwandler-Gruppe so zu gestalten, dass ihre Anforderungen an Objektiv und Bildverarbeitung anders und eventuell leichter realisierbar wären, und dass das störende Moire unterdrückt werden könnte.The protection specified in
Dieses Problem wird durch die im Schutzanspruch 1 aufgeführtes Merkmale – eine Kombination von teildurchlässigen Spiegeln und Mosaikfarbfiltern – gelöst.This problem is solved by the features listed in the protection claim 1 - a combination of partially transparent mirrors and mosaic color filters.
Die mit der Erfindung erzielten Vorteile, die einige Möglichkeiten zur Verbesserung der Bildqualität versprechen, bestehen insbesondere darin, dass mehrere konventionelle Bildwandler mit konventionellen oder einfacheren Bildverarbeitung und Objektiven genutzt werden können und das störende Moire durch Vergleich der Bilder der verschiedenen Bildwandler durch die Bildbearbeitung erkannt, lokalisiert und unterdrückt werden kann. Theoretisch reicht es aus, nur zwei Bilder der verschiedenen Bildwandler und nur einer Grundfarbe zu vergleichen, um die Bildung des störenden Moire zu erkennen, weil Muster des Moire, die sich an verschiedenen Bildwandlern bilden, sich wesentlich unterscheiden (siehe beispielsweise
Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben. Die Weiterbildung nach Schutzanspruch 2 stellt die einfachste Realisierung der Erfindung dar (
Eine andere vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 3 angegeben (
Eine andere vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 4 angegeben (
Eine unvermeidliche vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 5 angegeben. Erst die Weiterbildung nach Schutzanspruch 5 ermöglicht es, die erfundene Farbteiler-Bildwandler-Gruppe nutzen zu können: Sowohl ohne Positionierung und Befestigung der Teile als auch ohne andere Hauptelemente der Kamera geht es nicht.An inevitable advantageous embodiment of the invention is specified in the protection claim 5. Only the training for protection claim 5 makes it possible to use the invented color divider-image converter group: both without positioning and attachment of the parts and without other main elements of the camera is not.
