Abstract: Electronic images that are degraded by noise and data reduction, such as MPEG encoding, display artifacts in the reproduced image, such as ringing (“ripples”) and blocks (“huge pixels”), and noise in the image may be apparent as graininess. By performing image analysis, both on a frame-by-frame and pixel-by-pixel basis it is possible to identify and separate edges in the image, ringing artifacts and the boundaries between block transitions. By applying noise reduction according to the analysis, followed by sharpness enhancement, it is possible to clean up the image for further utilization.

Abstract: Although video display screens are factory calibrated to correct performance, they differ in the actual color balance presented to the viewer. Similarly, the output of video sources may vary, in particular from video cameras. For recalibration purposes, each video display screen is connected to the video source via a Central Processing Device, and each video display screen is calibrated when first installed by means of a test signal having a pre-defined color balance. The signal is analyzed by means of a three-color sensor, and the information is fed back to the Central Processing Device and stored along with a device identifier. Any subsequent video signal provided to a particular video display screen will be modified electronically by means of individual stored parameters. Video sources will have their output signals similarly modified after having been subjected to a similar analysis performed on a video display screen already calibrated.

Abstract: A system with a number of consumer electronics units interconnected by a digital data network, each of the units comprising a computer for controlling the functioning of the unit itself and the functioning in interplay with the other units in the network. The computer is provided with at least one general table with interrelated table entrances, wherein each available functional state of the unit and each available interplay with other units is given by an entrance in this at least one table.

Abstract: The invention relates to simulation of sound fields in enclosures, for instance for application in listening tests, where test subjects assess the sound quality or other sound perception characteristics of the sound field. According to a specific embodiment, the system comprises a binaural synthesis portion which synthesises sound for instance from a sound-reproduction equipment based on measured impulse responses of an actual room stored in a data base (31) and a binaural recording portion comprising a data base 32 for storing binaural recordings of other sound signals made in the room. Data from these databases are mixed (41) and reproduced by means of a headphone (39) provided with a head tracker (42) for tracking the movements of the listener's head. The invention furthermore comprises the use of cross-fading functions (36, 37) to enable the dynamic listening conditions, where the movements of the listener's head are taken into account during the simulation process.

Abstract: The present invention describes a multiple switch selection device where the movement of the first member may be very limited such that the overall construction height of the device may be very shallow, whereby the applications where such a multiple switch selection device can be built in, may be widened. Furthermore, it is also an object of the present invention to make the multiple switch selection device more versatile such that a wider range of input may be generated from one single device.

Abstract: The present invention relates to a modular loudspeaker, primarily intended to be used as a studio monitor and comprising a broadband module for radiating a first frequency range with a lower limiting frequency sufficiently low to provide a fully acceptable reproduction in many situations and furthermore provided with a high frequency radiating unit (and possibly also a mid frequency radiating unit), the directional characteristics of which relative to the cabinet of the module can be controlled. The modular loudspeaker according to the invention furthermore comprises one or more low frequency module(s) for radiating a second frequency range which may at least partially overlap said first frequency range for either increasing the acoustical output at the lower end of the frequency range radiated by the broadband module or for extending the lower limiting frequency of the complete modular loudspeaker below the lower limiting frequency of the broadband module.

Abstract: Displays for information exist, which appear to emerge out of a solid piece of metal. In order to obtain an aluminium-like and translucent material, according to prior art glass has aluminium vapour deposited onto the front surface, and a diode matrix display is hidden behind this translucent material while inactive, whereas it becomes visible when lit. In order to avoid the use of glass and to make the metal surface and the display surface indistinguishable from each other under all lighting conditions, the surface is made out of the piece of material constituting the surrounding parts. A cavity is formed from behind, and the bottom of said cavity is made very thin and hence translucent by etching or a similar material removing process. Oxide layers support this translucent layer, and an internal support is provided in the cavity, said support also carrying the sources of light.

Abstract: For determining a subjective property such as loudness of a binaural sound signal left and right sound pressures in the left and right ears of a human being, resulting from the binaural sound signal, are determined. The left and right ear and right sound pressures are frequency analyzed to obtain left and right frequency spectra. In each frequency band, the diotic (common) sound pressure in the left and right ears is determined, which would result from a plane wave frontal incidence on the human being, and that would produce the same perceived loudness as the frequency bandwidth limited left and right sound pressures. In each frequency band the inverse frontal headrelated transfer functions are used to determine the free-field sound pressure that would produce the same perceived loudness as the diotic sound pressure. The loudness is determined as the loudness of the totality of frequency bandwidth limited free field sound pressures, preferably using the international standard ISO 532.

Abstract: “Tilt mechanism for a device including a support member for supporting the device, a movable support member and a support structure. The support member is supported by the movable support member and the movable support member is supported by the support structure. The mechanism is further arranged to support the device essentially in a lateral direction of the movable support member, and the device may be supported by the mechanism in a state of equilibrium.
