Videoconferencing System Having Adjunct Camera for Auto-Framing and Tracking
First Claim
1. A videoconferencing method, comprising:
- capturing first video in a first view of an environment with a first camera;
detecting one or more faces of participants in the first video;
verifying at least one of the one or more detected faces as being reliable;
determining a boundary in the first view of the environment containing the at least one verified face;
adjusting a second view of a second camera to a framed view of the environment based on the determined boundary; and
capturing second video in the framed view with the second camera.

Abstract
A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, faces of participants are detected, and a boundary in the view is determined to contain the detected faces. Absence and presences of motion associated with the detected face is used to verify whether a face is reliable. To then capture and output video of the participants for the videoconference, the view of the adjustable camera is adjusted to a framed view based on the determined boundary. In the end, active video captured in the framed view with the adjustable camera can be sent to a far-end for the videoconference.
