Abstract:
1. An image display terminal comprising: an image display control unit which displays a background image in a display screen of the image display terminal; a display range setting unit which sets, with respect to a coordinate system determined by a plurality of coordinate axes, display range data to an image display region where the background image is displayed of the display screen; a display range sending unit which sends the set display range data to at least two other image display terminals; a graph expression receiving unit which receives from the other image display terminals, after the sent display range data is set to an image display region where the background image is displayed of the other image display terminals, graph expression data for a graph figure displayed on the background image of the other image display terminals, wherein the background image displayed on the image display terminal and the background image displayed on the other image display terminals are identical; a terminal information receiving unit which receives, from the other image display terminals, terminal information on the other image display terminals when the graph expression receiving unit receives the graph expression data from the other image display terminals; a terminal information display control unit which displays the received terminal information on the display screen; and a received graph display control unit which displays, on the background image, the graph figure shown by the graph expression data received by the graph expression receiving unit; wherein, when the graph expression receiving unit receives the graph expression data from each of the other image display terminals, and the terminal information receiving unit receives the terminal information from each of the other image display terminals, the received graph display control unit and the terminal information display control unit display the graph figure shown by the received graph expression data and the received terminal information in such a way that the graph figure and the terminal information are correlated with each other, with respect to each of the other image display terminals.
