发明名称 Voice-following video system
摘要 <p>A voice-following video system (100) for dynamically capturing the view of an active speaker includes a video camera (102), a position control system (106) for the video camera, and one or more voice-activated emitters (104). A voice-activated emitter (104) is associated with each potential speaker. As a person talks, the associated voice-activated emitter transmits a position signal. The position control system (106) uses the position signal as a beacon to determine the location of the active speaker. The position control system then adjusts the pan and/or tilt of the video camera (102) to bring the active speaker into the field of view and tracks that person's movements. In this manner, as one person stops speaking and another starts, the video camera is automatically repositioned, capturing the view of the active speaker. &lt;IMAGE&gt;</p>
