ABSTRACT:
The present invention provides a technique for obtaining a sharp video image from a plurality of frames during a multimedia teleconference. Video data is acquired by a camera on a first processing system in the form of a number of frames. The frames are transmitted to a second processing system, which combines corresponding pixel values from each of a series of initial frames to produce an output frame. The process is repeated to generate a number of output frames, which are displayed on the second processing system.
