Abstract
A method for automatically correcting frame faults in video assist frames of a video assist system in a video beam path branched off from a capture beam path of a motion-picture camera, a ground glass screen being arranged in said video beam path, is provided. The video assist system is calibrated by capturing at least one video assist frame of a single-colored, unstructured and uniformly illuminated, flat capture object for a predefined diaphragm aperture of the camera lens and storing it as a video assist calibration frame in a frame store, wherein the stored and inverted video assist calibration frame is superimposed on the video assist frames captured after the calibration.
