Patent ID: 8218034

Claim:
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, wherein a ground glass screen is arranged in said video beam path, wherein the video assist system is calibrated by capturing a plurality of video assist calibration frames of a single-colored, unstructured and uniformly illuminated, flat capture object using at least one of different camera lenses or different diaphragm apertures of the camera lenses or different diaphragm apertures of a video assist lens, the brightness values of a plurality of areas of the video assist calibration frames are stored depending on the camera lenses used or the different diaphragm apertures of the camera lenses used or the different diaphragm apertures of the video assist lens used, and the stored brightness values of the plurality of areas of the video assist calibration frames are superimposed on the video assist frames captured after calibration, wherein the brightness values of the pixels of a plurality of video assist calibration frames captured using the same camera lens are captured with the setting of the camera lens or the diaphragm aperture of the camera lens remaining constant and the setting of the diaphragm aperture of a video assist lens remaining constant and an average value of the brightness of all the pixels of the captured video assist calibration frames is formed, which is assigned to the individual pixels of the video assist frames captured after the calibration.
