Abstract

Es wird ein Verfahren zur Steuerung der Empfindlichkeit mindestens eines Mikrofons (1, 5) vorgeschlagen. Dabei werden Videodaten einer Schallquelle (10), insbesondere einer Sprachquelle, von einer Kamera (15) aufgezeichnet. Die Kamera (15) ist dabei in einer vorgegebenen Position relativ zum mindestens einen Mikrofon (1, 5) angeordnet. In Abhängigkeit der aufgezeichneten Videodaten und/oder einer Fokuseinstellung eines Objektivs (20) der Kamera (15) wird eine Position der Schallquelle (10) relativ zum mindestens einen Mikrofon (1, 5) ermittelt. Die Empfindlichkeit des mindestens einen Mikrofons (1, 5) wird in Abhängigkeit der ermittelten Position eingestellt.

A method for controlling the sensitivity of at least one microphone (1, 5) is proposed. In this case, video data of a sound source (10), in particular a voice source, are recorded by a camera (15). The camera (15) is arranged in a predetermined position relative to the at least one microphone (1, 5). Depending on the recorded video data and / or a focus setting of an objective (20) of the camera (15), a position of the sound source (10) relative to the at least one microphone (1, 5) is determined. The sensitivity of the at least one microphone (1, 5) is set as a function of the determined position.
