20100219758 | LIGHTING DEVICE COMPRISING A PLURALITY OF CONTROLLABLE LIGHT-EMITTING DIODES - A lighting device comprising a plurality of lighting modules which include a module carrier on which a light source with a plurality of controllable light-emitting diodes emitting light of different wavelengths and arranged on a board, a temperature sensor and a module electronic are arranged. Said module electronic contains a digital circuit with a microcontroller for the local and autonomous signal processing, which actuates the LEDs in dependence on the temperature such that the brightness, color and chrominance of the light mixture composed of the LEDs emitting light of different wavelengths is constant. Said lighting modules being connected with other lighting modules or an external controller via a digital interface for transmitting the board temperature of the respective lighting module detected by means of the temperature sensor. A central master module or the external controller actuates the lighting modules such that a uniform brightness is obtained over the radiating surface. | 09-02-2010 |

20100176734 | Method and device for driving light-emitting diodes of an illumination device - A method for driving series-connected light-emitting diodes of an illumination device, in particular an illumination device for film, video and photographic recordings with a pulse-width-modulation of the light-emitting diode current, is provided. In the method the pulse-width-modulated light-emitting diode current is detected and a current sensor signal is derived and fed to a microprocessor, which outputs a drive signal for the pulse-width-modulation and for the setting of the light-emitting diode voltage applied to the light-emitting diodes, depending on the detected current sensor signal. The current-time integral of the pulse-width-modulated light-emitting diode current flowing through the light-emitting diodes is determined and a controllable voltage source for setting the light-emitting diode voltage is driven in such a way that a predetermined pulse-width-modulated light-emitting diode current flows through the light-emitting diodes. | 07-15-2010 |
20110286074 | Device for Inserting Information into the Finder Beam Path of a Motion Picture Camera - A device for inserting information into the finder beam path of a motion picture camera comprising an imaging optics and a DMD chip are arranged with a multiplicity of micromirrors that are arranged in the form of a grid and can be swiveled under electronic control. One portion of the micromirrors reflects the finder beam path toward the imaging optics, and the other portion of the micromirrors is swiveled at least temporarily out of the finder beam path, and respectively reflects toward the imaging optics a section of an information surface arranged laterally offset from the finder beam path. | 11-24-2011 |

20080284899 | Method for Focusing the Shooting Lens of a Motion Picture or Video Camera - A method for focusing the shooting lens of a motion picture or video camera onto a moving or stationary object, which is imaged on a monitor of a display instrument is provided. The solution according to the invention uses a distance measurement instrument which is aligned or tracked in relation to a predetermined alignment of the distance measurement instrument at the object as a function of the image angle of an imaging lens of the display instrument and the coordinates of the image of the object on the monitor of the display instrument. The horizontal and vertical angle deviations of the object from the camera are calculated from the coordinates of the image of the object on the monitor and delivered as setpoint values to the control instrument of an adjustment instrument holding the distance measurement instrument for aligning or tracking a measurement head of the distance measurement instrument. | 11-20-2008 |
20090051806 | Device for Connecting a Camera Lens to a Movie Camera - A device for connecting a camera lens to a movie camera has a camera housing with a lens mount and a device for acquiring data relating to the camera lens connected to the lens mount. Said device further comprising a miniaturized electronic system with data memory for storing data relating to the camera lens such as lens type, serial number, conversion tables and the like, and with a contact region that is arranged on a data interface between the lens mount of the movie camera and the lens fastening means of the camera lens and which is aligned with the contact region arranged in the lens mount of the movie camera is integrated in the lens fastening means of the camera lens or in a modified lens fastening means connected to the lens fastening means of the camera lens or replacing the latter. | 02-26-2009 |
