摘要: Video processing for enhancing contrast includes detecting the ambient light levels on a display, performing local contrast enhancement processing to emphasize the luminance component based on the detected ambient light levels to provide a processed video signal, and presenting the processed video signal on the display.

摘要: Electroacoustical apparatus includes at least first and second acoustically coupled electroacoustical drivers. An electrical network couples their inputs so that an electrical drive signal applied to one reduces the effect of acoustic coupling from that one to the other.

摘要: An three-way audio system that uses directional arrays for radiating mid-frequency acoustic energy and passive directional devices to radiate the high frequencies. the system includes a left channel, a right channel, and a center channel. A crossover network separates the left channel and the right channel into low frequency content, midrange frequency content, and high frequency content. An omnidirectional acoustical device radiates acoustic energy corresponding to the low frequency content of the combined left channel, right channel and center channel. A first directional array, comprising signal processing circuitry and more than one acoustic driver, radiates acoustic energy corresponding to the midrange content of one of the left channel and right channel signal so that more acoustic energy corresponding to the midrange content of one of the left channel signal and the right channel signal is radiated laterally than in other directions. A first passive directional device, radiates acoustic energy corresponding to the high frequency content of the one of the left channel and right channel signal so that more acoustic energy corresponding to the high frequency content of the one of the left channel signal and the right channel signal is radiated laterally than in other directions.

摘要: An audio system including a rendering processor for separately rendering a dialogue channel and a center music channel. The audio system may include circuitry for extracting one or both of the dialogue channel or the center music channel from program material that does not include both a dialogue channel and a center music channel. The dialogue channel and the center music channel may be radiated with different radiation patterns.

摘要: Audio electrical signals are controlled to be provided to a plurality of electroacoustical transducers of an array to achieve directivity and acoustic volume characteristics that are varied with respect to a parameter associated with operation of the array. The controlling of the signals results in a change in the radiated acoustic power spectrum of the array as the characteristics are varied. The change in the radiated acoustic power spectrum of the array is compensated.
