Description
Kamera zur Herstellung der Teilbilder von lWehrfarbenaufnahmen oder gleichzeitigen Vervielfältigung einer gewöhnlichen Aufnahme. Die Erfindung betrifft eine Kamera zur Herstellung von Mehrfarbenbildern nach einem auf einer durchscheinenden Fläche (Mattscheibe) erzeugten Bilde. Eine solche Kamera ist bekannt. Bei dieser wird das Mattscheibenbild durch ein Objektiv entworfen. Hierbei geht viel Licht verloren, so daß farbige Aufnahmen sich bewegender Objekte wegen ungenügender Helligkeit nicht möglich sind. Um nun ein Mattscheibenbild von möglichst großer Helligkeit zu erzeugen, ist nach der Erfindung gegenüber der Mattscheibe ein. schräg zur optischen Achse der Aufnahmeobjektive stehender Hohlspiegel angebracht.Camera for the production of partial images of military color recordings or simultaneous duplication of an ordinary recording. The invention relates to a camera for producing multicolor images after one on one translucent Surface (focusing screen) generated images. Such a camera is known. At this the focusing screen image is designed by a lens. There is a lot of light here lost, so that colored images of moving objects due to insufficient brightness are not possible. To get a screen image of the greatest possible brightness to produce is according to the invention compared to the ground glass. oblique to the optical Axis of the taking lenses of standing concave mirror attached.
Es wird bemerkt, daß Hohlspiegel zur Erzeugung von Mehrfarbenbildern an sich bekannt sind. Die Achse dieser Hohlspiegel fällt aber mit der optischen Achse der Vorrichtung zusammen; nur in dem mittlerem. Spiegelteil sind die Objektive angebracht, so daß dieser Teil für die Erzeugung des Bildes verloren geht.It is noted that concave mirrors are used to produce multicolor images are known per se. The axis of this concave mirror coincides with the optical one Axis of the device together; only in the middle one. The mirror part are the lenses attached so that this part is lost for the creation of the image.
Die Zeichnung zeigt ein Ausführungsbeispiel der Kamera im Horizontalschnitt. In der Kamera s4 ist schräg zur optischen Achse eine verstellbare Hohlspiegelhälfte B und eine feststehende Mattscheibe C angebracht, welche sich an einem Prisma D für die ,Weiterleitung des Mattscheibenbildes zur Aufnahmekamera E befindet. Letztere kann sich auch. unmittelbar an die Mattscheibe anschließen. Die Öffnungsweite zur Brennweite des Hohlspiegels erhält ein solches Verhältnis, daß die Helligkeit des Mattscheibenbildes mindestens der vorhandenen Objekthelligkeit entspricht.The drawing shows an embodiment of the camera in horizontal section. In the camera s4 there is an adjustable concave mirror half at an angle to the optical axis B and a fixed focusing screen C attached, which is attached to a prism D for forwarding the focusing screen image to the recording camera E. Latter can also. connect directly to the ground glass. The opening width for The focal length of the concave mirror is given such a ratio that the brightness of the The focusing screen image corresponds at least to the existing object brightness.
Der aufzunehmende Gegenstand muß sich auf derselben Seite wie die fehlende Spiegelhälfte 'befinden, damit die Lichtstrahlen den Spiegel treffen und das Mattscheibenbild entwerfen können. Für besondere Zwecke kann auch ein ganzer Hohlspiegel .angebracht sein, ebenso statt der Mattscheibe eine vollkommen lichtundurchlässige weiße Fläche (Bildschirm). Die Kamera ist sowohl für Kino-und Portraitaufnahmen als auch für jede andere Art von Mehrfarbenaufnahmen verwendbar sowie zur gleichzeitigen Vervielfältigung einer gewöhnlichen Aufnahme.The object to be picked up must be on the same side as the missing mirror half 'so that the light rays hit the mirror and be able to design the screen image. For special purposes, a whole can also be used Concave mirror .be attached, as well as a completely opaque one instead of the ground glass white surface (screen). The camera is suitable for both cinema and portrait photography as well as for any other kind of multicolor recordings as well as for simultaneous use Reproduction of an ordinary recording.
