Abstract

1513813 Cine and television apparatus ROBERT BOSCH GmbH 9 June 1975 24587/75 Heading G2E [Also in Division H4] Television cameras 1 and 3 are located on a common optical axis and light from selected projectors 5, 6, 7, 8 is directed into the cameras by a prism arrangement 9, 10 so that one camera 1 can be used to transmit the images from one projector while the other camera 3 is used to preview the images from a different projector. As shown, the reflective hypotenuse 14 of prism 9 reflects light from cine projectors 6 and 8 to cameras 1 and 3 respectively. By replacing prism 9 by prism 10, the reflective hypotenuse 14' of prism 10 will reflect light from projectors 6 and 8 to camera 3 and 1 respectively. By shifting mirrors 11 and 12, projectors 5 and 7 can be used. In Fig. 2 (not shown), additional mirrors (16 to 21) enable light from two projectors on the same side of the camera axis to be directed to the cameras.
