ABSTRACT:
A method for controlling an imaging beam path which is tapped off from a film recording beam path of a movie camera and is interrupted periodically as a function of the image recording frequency of the movie camera is provided. The imaging beam path is interrupted at a constant or variable frequency by means of an optical switching element during the exposure phase of the movie film, or is deflected from a first imaging plane to at least one second imaging plane, or to a light trap. An apparatus comprising at least one DMD-chip which is arranged in the imaging beam path of the movie camera and has micromirrors which are arranged in the form of a raster, can be pivoted under electronic control, and deflect an incident beam path to a first or a second imaging plane, or into a light trap.
