ABSTRACT:
Image transmission method and apparatus for transmitting/receiving images among a plurality of terminals connected to a network, and an image transmission system including the apparatus. A video camera (30) is connected to each of a plurality of video communication terminals connected to a network (12), and an image picked up by the camera (30) of each terminal is exchanged with another communication terminal via the network (12). In this case, in a certain terminal, a plurality of images received from other terminals are displayed on a display (26), and the names of terminals which are receiving the image picked up by the video camera (30) of the terminal, and the name of a terminal (or the name of an operator) which is operating the video camera (30) of the terminal are also displayed on the display (26). Each terminal displays, on the display (26), an icon which allows an operator to recognize at a glance whether or not an image picked up by the camera of its own terminal is being monitored by another terminal, or generates a warning tone in correspondence with the monitor or operation state of the video camera (30) of its own terminal, thereby calling for an attention of the operator of its own terminal.
