20090002495 | Method for Monitoring Set Parameters of a Motion-Picture Camera - A method for monitoring set parameters of a motion-picture camera is provided. Film images, which are extracted from a recording beam path of the motion-picture camera and which are converted into digital assist signals by an optoelectronic transducer are arranged in an assist beam path of the motion-picture camera. Digital assist signals are output to a processing unit with an image frequency matching the image recording frequency of the motion-picture camera or with an assist image frequency, to which processing unit recording, control and/or status signals of the motion-picture camera or of devices connected to the motion-picture camera are additionally fed as metadata. The processing unit analyzes digital assist images composed of the digital assist signals and outputs digital output data and control signals to control modules of the motion-picture camera and/or to a network, and/or as analog or digital video signals to a monitor connected to the processing unit. | 01-01-2009 |
20090002511 | Method For Automatically Correcting Frame Faults in Video Assist Frames of a Video Assist System - 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. | 01-01-2009 |
20090046155 | Method for Processing Film Images Extracted From a Film Recording Beam Path of a Moving Image Camera - A method for processing film images which are extracted from a recording beam path of a moving image camera and which are converted into digital assist signals by an optoelectronic transducer arranged in an assist beam path of the moving image camera is provided. Said assist beam path being interrupted periodically depending on the image recording frequency of the moving image camera, which digital assist signals are output to a processing unit with an image frequency matching the image recording frequency of the moving image camera or with an assist image frequency, to which processing unit recording, control and/or status signals of the moving image camera or of devices connected to the moving image camera are fed as metadata. The processing unit contains image conditioning functions and/or image analysis functions. | 02-19-2009 |
20100265464 | Viewfinder System for a Camera - A viewfinder system for a camera, in particular a movie camera, in which there runs a viewfinder beam path that is diverted from a recording beam path for film exposure is provided. The viewfinder system comprising an eyepiece, an eye closure, a shutter for masking out stray light penetrating into the camera via the viewfinder system, and a control device that triggers the shutter and is connected to a sensor. The viewfinder system further comprising a sensor device for contactless detection of an eye or head, located at the eye closure of the viewfinder system, of a person viewing the picture to be recorded through the eyepiece. | 10-21-2010 |
20110194021 | METHOD AND DEVICE FOR CONTROLLING THE CONTRAST RANGE OF AN IMAGE CAPTURING LIGHT FALLING ON AN IMAGE CAPTURING MEDIUM - A method for controlling the contrast range of the image recording light falling on an image recording medium by means of control light coupled into the optical path of the image recording light, which is composed of several base colors whose brightness is adjusted independent of each other, is provided. The brightness at least of those base colors of the control light is varied, whose dynamics in the recorded image go beyond the admissible dynamic range. | 08-11-2011 |
20120033932 | METHOD AND DEVICE FOR EDITING RECORDED IMAGES OF A DIGITAL VIDEO CAMERA - A method for editing recorded images from a digital video camera. which images are projected from a cine lens connected to the digital video camera onto an imaging disk and, from the latter, onto an electronic sensor assembly, which converts the recorded images into recording signals provided as raw or RGB data, is provided. At least one calibration image is recorded, from which correction values are calculated for the grain structure of the imaging disk and/or the vignetting in the edge region of the recorded images. The recorded images are linked to the correction values. | 02-09-2012 |
