1. A three dimensional (3D) video communication method comprising: acquiring a plurality of two dimensional (2D) images corresponding to a talker, by using a 3D camera; detecting an object located between the talker and the 3D camera using the acquired plurality of 2D images; scaling an original sense of depth of the detected object to a new sense of depth; and generating a 3D talker image including the object with the new sense of depth and transmitting the 3D talker image to a 3D video communication apparatus of a listener.
