Abstract
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.
Claims20
A camera system for extracting sounds of a specific area, comprising:
- 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.
A method for operating a camera system for extracting sounds of a specific area, the method comprising:
- receiving video signals and audio signals from an area;
- storing information about the area including the video signals and the audio signals;
- generating a sound-based heatmap for the area based on the information about the area;
- selecting a user-designated area to perform beam-forming thereon and selecting a first point in the user-designated area as an audio zooming point;
- changing the audio zooming point to a second point in the user-designated area based on the first point and the sound-based heatmap;
- and
- performing the beam-forming in a direction corresponding to the second point.
