Device and method for determining a reproduction position

A device for determining a reproduction position of a source of sound for audio-visual reproduction of a film scene from a plurality of individual pictures with regard to a reproduction surface having a predetermined width and a projection source having a projection reference point comprises means for providing a recording position of the source of sound, a camera position during recording, and an aperture angle of the camera during recording. In addition, provision is made of means for transforming the recording position of the source of sound to a camera coordinate system, the origin of which is defined, in relation to a camera aperture, to obtain a recording position of the source of sound in the camera coordinate system. Means for calculating the reproduction position of the source of sound in relation to the projection reference point determines whether the aperture angle of the camera equals a predetermined aperture angle, and whether or not a source of sound is located within the visual range of the camera. If the current aperture angle of the camera differs from the predetermined standard aperture angle, the reproduction position of the source of sound is spaced toward a viewer, or away from the viewer, by a distance which depends on the ratio of the standard aperture angle to the current aperture angle. Hereby, automatable sound-source positioning is achieved so as to provide not only a visually realistic, but also an acoustically realistic situation in a reproduction room using wave-field synthesis methods.

Optical detection device for detecting an intensity of a light beam and for detecting data transmitted by the light beam

An optical detection device for detecting an intensity of a light beam in a detection window and for detecting data transmitted by the light beam includes a first detection diode and an array of at least two second detection diodes in a detection window. In addition, provision is made for a first readout circuit connectable to the first detection diode, for reading out the first detection diode at a first readout speed to detect the data, and for a second readout circuit connectable to the second detection diodes, for reading out the second detection diodes at a second readout speed smaller than the first readout speed, so as to detect the intensity of the light beam. A fundamental consideration underlying the present invention is that although the provision of additional detection diodes in the detection window initially is associated with additional expense and a reduction of the surface area of the detection window which may effectively be utilized for data detection, these disadvantages are outweighed however, by the fact that this array of additional detection diodes in the detection window enables more effective and / or less expensive control of the alignment of the light beam transmitting the data with the detection window.

Method for Determining an Averaged Frequency-Dependent Transmission Function for a Disturbed Linear Time-Invariant System, Evaluation Device and Computer Program Product

The invention relates to a process for determining an averaged frequency-dependent transfer function for a perturbed linear time-invariant system by means of an evaluation device, wherein the process comprises providing frequency-dependent reference signals derived from excitations input in a linear time-invariant system, providing frequency-dependent measuring signals for the linear time-invariant system associated with the frequency-dependent reference signals, and determining an averaged frequency-dependent transfer function for the linear time-invariant system, in that, using signal deconvolution of mutually associated measuring and reference signals, frequency-dependent transfer functions are determined and the frequency-dependent transfer functions are averaged, and wherein during determination of the averaged frequency-dependent transfer function at least a part of the determined frequency-dependent transfer functions is included in the averaging corresponding to a respectively associated frequency-dependent weighting. Furthermore the invention comprises an evaluation device for determining an averaged frequency-dependent transfer function for a perturbed linear time-invariant system and a computer program product.
