ABSTRACT:
In a communication conference method which uses display units in order to display handwritten inputs, handwritten input signals are transmitted between first and second terminals to perform a communication conference session. Information concerning numbers of pixels of the display units are exchanged between the first and second terminals. The next step is to set a common display area used in the communication conference session. The common display area has the smaller of the number of pixels of the first terminal and the number of pixels of the second terminal.
