In a case where a display control apparatus displays images A and B from respective PCs, a positioning operation using a positional device is started in an area of image A and continuously preformed in the area of that image. The apparatus determines whether or not a position designated in the area of image A has a predetermined positional relationship with an area of image B, partly covering the image A. If it is determined that the designated position has the predetermined positional relationship with the area of image B, the apparatus makes image B transparent. The apparatus then issues coordinates data indicating the designated position in the area of image B, to the PC for outputting image A. |
