Abstract
An audio/video (A/V) capture device and method that capture audio and video in a spatially synchronized manner. In one implementation, the device and method automatically adjust the shape of a spatial directivity pattern of a microphone array used for acquiring audio so that the pattern is spatially synchronized with an amount of video zoom being applied by a video acquisition section to acquire video. For example, a wider spatial directivity pattern may automatically be used during wide-angle shots and a narrower spatial directivity pattern may automatically be used during close-ups. This beneficially allows for the consistent attenuation of audio signals received from audio sources that lie outside the field of view of the video acquisition section while passing or even enhancing audio signals received from audio sources that lie within the field of view even though the width of the field of view has changed.
