<p>PURPOSE:To display information on a screen when a synchronous state and a reference object are inputted and to speed up the display of the information by the transmission of essential elements by solving the problem that a conventional shared screen display device has no discrimination between common handling case and individual handling case. CONSTITUTION:For screen operating motion, a central synchronous control part 123 performs central control over the changing of the synchronous state of a display screen by synchronism information input, the specification of an object with which the display screen is synchronized by synchronism condition input, and the displaying of an area common to the object principally by a synchronous control part 106. Further, the reference area of the object can be displayed by specifying the reference object. Further, the display operation is made faster by transmitting essential elements in advance for the transmission of image information.</p> |
