Classification: CPC H  G | IPC G  H

Claim 10:
11. An automated method for auto-focusing a camera on a person in a venue who is wearing, or carrying, or holding, or speaking into a microphone at the venue, the venue including a real-time location system (RTLS) having a RTLS tag and a RTLS receiver for locating a position of the RTLS tag in three-dimensional space, wherein the RTLS tag is fixed to the microphone and transmits a signal that is received by the RTLS receiver, the method comprising:
(a) detecting when the microphone is active;
(b) identifying, using the RTLS, the position of the RTLS tag in three-dimensional space in the venue by using the signal transmitted from the RTLS tag and received by the RTLS receiver to calculate the position of the RTLS tag in three-dimensional space,
wherein the position of the RTLS tag in three-dimensional space in the venue is presumed to be the same position as the microphone that the RTLS tag is fixed to; and

(c) auto-focusing the camera on the identified position of the RTLS tag in the three-dimensional space in the venue when the microphone is active, the camera thereby outputting a video signal of an area that is in proximity of the RTLS tag which is presumed to include an image of the person in the venue who is wearing, or carrying, or holding, or speaking into the microphone having the RTLS tag fixed thereto.
