Appeal No. 1998-0875
Application No. 08/210,529
in the method and apparatus to create synthesized frames
representative of an image of the person speaking to thereby
increase the frame rate of the video signal.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. An apparatus for increasing the frame rate of a
received video signal representative of a sequence of
images of a speaking person and having a first frame rate,
comprising:
a monitoring system for monitoring an audio signal
temporally corresponding to the sequence of images to
detect speech segments uttered by the speaking person, at
least some detected speech segments corresponding to
images of the image sequence that are not represented by
the received video signal;
an associating system for associating detected
speech segments with stored parametric mouth formation
data; and
a frame generating system, responsive to said
monitoring system and said associating system, for
generating at least one synthesized frame representative
of an image of the speaking person and for inserting said
at least one synthesized frame between adjacent frames of
the received video signal to thereby provide a video
signal having a frame rate higher than said first frame
rate.
