摘要:
A camera system for extracting a sound of a specific area includes: a camera device configured to receive video signals and audio signals from an area; at least one memory configured to store information about the area including data corresponding to the video signals and the audio signals from the area; and a processor configured to change an audio zooming point of the camera device from a first point, in an image of the area captured by the camera device, to a second point based on the information about the area, and perform a beam-forming on an audio signal corresponding to the second point.
