Patent ID: 8761412

Claim:
A method of focusing a microphone array, comprising: receiving an audio signal from the microphone array, the microphone array disposed a distance away from a first component of an audio beam forming system; receiving a visual image from a plurality of images forming a video segment from an optical image sensor having a known position relative to the microphone array, the visual image including the first component within a field of view (FOV); determining positional information for the first component, relative to the microphone array by analyzing the visual image, and by determining a distance between the first component and the image sensor based on a predetermined size of the first component; tracking a change in the position of the first component relative to the image sensor based on changes in the visual image within the video segment; and filtering the audio signal to emphasize or de-emphasize audio sources proximate to the first component based on a beam forming algorithm that is a function of the positional information and on the change in the position of the first component.
