(57) Abstract :
In videoconference camera selection, audio inputs associated with cameras for a videoconference are each processed into first and
second audio energies respectively for first and second frequency ranges. The selection then determines which of the audio inputs
has a greatest ratio of the first audio energy to the second audio energy and selects the associated camera view for outputting video
for the videoconference. The selection can also process video inputs from the cameras either alone or in combination with the
audio processing. Either way, the selection processes each of the video inputs for at least one facial characteristic and determines
which of the video inputs has a greatest likelihood of framing a human face. In the end, the selection selects the associated camera
view for outputting video for the videoconference based at least in part on this video-based determination.
