<p>PURPOSE: To reduce the overlap of windows by changing the positions of windows and changing also the sizes of the windows when the windows are mutually overlapped. CONSTITUTION: An overlap judging means 120 inputs the coordinates of windows and a display reference based upon a display command, judges whether the windows are mutually overlapped or not, and when these window are not suited to the reference, outputs a position changing command. At the time of receiving the command, a position changing means 121 changes the positions of the windows, outputs a 2nd picture display command to display a 2nd picture on a display means 130, and at the time of judging that the windows can not be suited to the display reference only by the change of the positions, outputs a size changing command. A size changing means 122 inputs the size changing command, the coordinates of the windows, a display command, and the display reference, changes the sizes of the windows, and outputs a 3rd picture display command to display a 3rd picture on the display means 130. Consequently the overlap of plural pictures can be reduced and the visibility and operability of multi-window display can be improved.</p> |
