The first image display apparatus transmits a first image including a photographed image of a first user to the second image display apparatus, and receives a second image in which a background of a photographed image of a second user is substituted with a virtual background image, from the second image display apparatus. The second image display apparatus changes the virtual background image of the second image according to a change in a location of the first user and transmits the second image.
