Patent Images
1. A method of tracking a position of a head of a listener, the method comprising:
- obtaining two images of the listener respectively using two image pickup units;
tracking a skin color of one of the images, thereby obtaining a 2-dimensional (2D) coordinate value of the position; and
obtaining a distance between the image pickup units and the listener using stereo area correlation.

Abstract
A method and apparatus for tracking a listener'"'"'s head position for virtual stereo acoustics. The method of tracking the head position of a listener includes: obtaining face images of the listener using two image pickup units; tracking the skin color of an image, thereby obtaining the two-dimensional (2D) coordinate value of the listener'"'"'s position; and obtaining the distance between the image pickup units and the listener using triangulation.

6. An apparatus for tracking a position of a head of a listener, the apparatus comprising:
-
a first image pickup unit capturing a first image of the face of the listener; a second image pickup unit capturing a second image of the face of the listener from a second angle of vision different from the first; a 2-dimensional (2D) coordinate value generation unit generating a 2D coordinate value of the position by tracking a skin color of the image; and a distance calculation unit calculating a distance between the image pickup units and the listener using stereo area correlation. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus, comprising:
-
two image pickup units respectively capturing two images of a face; a 2-dimensional coordinate value generation unit generating a 2D coordinate value of a position of the face by tracking a skin color region of one of the captured images; and a distance calculation unit calculating a distance from the image pickup units to the listener using stereo area correlation of the two images.

12. A method, comprising:
-
capturing two images of a listener'"'"'s face from different perspectives via two image capturing units; determining a 2D coordinate position of the face by tracking a skin color region of one of the captured images; and calculating a distance from the image capturing units to a head of the listener via triangulation based on the two images. - View Dependent Claims (15)

13. A method of resetting a location of a sweet spot, comprising:
determining a position of head of a listener by capturing two images of a listener'"'"'s face from different perspectives via two image capturing units, determining a 2D coordinate position of the face by tracking a skin color region of one of the captured images, and calculating a distance from the image capturing units to a head of the listener via triangulation based on the two images; and resetting a sweet spot to coincide with the determined position. - View Dependent Claims (16)
