Abstract
The invention relates to a device for improving image quality in focusing screens of an optical representation system of a movie camera, having a movably mounted translucent disk in a sandwich structure, a drive device moving the movable disk in the plane of the disk and a stationary disk mounted parallel to the plane of the movable disk with an image field marking. The drive device is connected to the movable disk and moves the movable disk at least temporarily, for instance during the “standby mode” of the movie camera, at a frequency depending on the image frequency of the movie camera, the video frequency of a video reflecting device of the movie camera or motion picture camera or the brightness of the image or subject to be recorded or with a high motion frequency independent of the operating state of the movie camera.
