GENERATION OF AN AUDIOVISUAL SIGNAL

An apparatus comprises receivers (101, 102) receiving microphone signals and a video signal capturing a scene. An image generator (113) generates an image signal comprising images generated from the video signal and a zoom determiner (115) determines a zoom property, such as a zoom factor, for the i...

Zusammenfassung:	An apparatus comprises receivers (101, 102) receiving microphone signals and a video signal capturing a scene. An image generator (113) generates an image signal comprising images generated from the video signal and a zoom determiner (115) determines a zoom property, such as a zoom factor, for the images. An audio component generator (107) generates a stereo signal component for a given mono audio signal to comprise the mono audio signal positioned at a position in a stereo image of the stereo signal component. A combiner (109) generates the stereo audio signal to include at least one stereo signal component and an output (111) generates the audiovisual signal to comprise the stereo audio signal and the image signal. In the approach the position is determined in dependence on the zoom property, and typically also dependent on a direction of arrival for the given mono audio signal. The approach may allow closer consistency between visual and auditory spatial cues.
