  • Publication number: 20200253017
    Abstract: In a method for controlling a lighting device having at least two illuminants with different emission characteristics, in a detection step, at least one actual temperature value, and, during a predeterminable detection period, at least one temperature-change information are detected, in a control-signal generating step dependent upon the at least ore detected actual temperature value and the at least one temperature-change information, new control signals are determined for the respective control of the at least two illuminants for the emission of a predetermined spectral power distribution are determined with the lighting device and in a control step, the new control signals are transmitted to an operating device by which the operating current for each illuminant is provided, in order to keep the spectral power distribution emitted by the lighting device possibly constant dining operation of the lighting device.

  • Patent number: 8134632
    Abstract: The invention relates to a digital motion picture camera including at least one optoelectronic sensor device for the recording of motion pictures. The sensor device has, in an areal arrangement, a plurality of sensor elements for the generation of a respective received signal in dependence on a light exposure. The camera further has a control device for the controlling of the read-out of the received signals of the sensor elements as well as a digitizing device for the digitizing of the received signals. The camera moreover has an optical viewfinder for the visual observation of the motion pictures to be recorded and a beam deflection device which is interposed in front of the sensor device and by which the reception beam path can be split at least into one recording beam path for the sensor device and one viewfinder beam path for the optical viewfinder.

  • Patent number: 8063937
    Abstract: An electronic motion picture camera for recording a sequence of images includes a sensor device having a two-dimensional arrangement of sensor elements that generate electrical signals in dependence on an exposure to light. A first group of the sensor elements forms a recording region of the sensor device and generates recording signals, and a second group of the sensor elements forms a monitoring region of the sensor device and generates monitoring signals, wherein the monitoring region surrounds the recording region. A memory device stores the recording signals, but not the monitoring signals. A display device displays the recording signals, the monitoring signals and a frame signal representing a border between the recording region and the monitoring region of the sensor device, and the border between the recording region and the monitoring region is kept fixed during the recording of the sequence of images.
