PURPOSE:To ensure the smooth execution of communicating operations of a still picture conference equipment by showing a marker at a handwrite input operation position on a common screen to point this position when a handwrite input operation is carried out by a terminal having no transmission right. CONSTITUTION:An application monitors a fact that the touch input of a touch panel 6 is detected. When either one of touch coordinates is supplied from a touch panel device together with a touch input, a touch panel controller 26 checks whether the value of the relevant touch coordinate information is included in a prescribed area or not. If so, it is cheched whether its own terminal has acquired a token or not. If so, the prescribed drawing processing is carried out based on the touch coordinates. Then the drawing information acquired by the drawing processing is sent to a terminal of the opposite party side. If the token is not acquired, a prescribed marker image is shown on the display screen of its own terminal at a position corresponding to the relevant touch coordinate information. Then the marker display information is generated and sent to the terminal of the opposite party side. |
