A display processing device for displaying a display object in a display window and changing a display range includes a sectioning unit that divides the display window into a plurality of sections (screens) by creating boundary lines. Maps of geographical ranges to be displayed are sectioned and displayed in the plurality of screens. In the event that a boundary line is moved through a user input, the geographical ranges of the maps in the screens for which the screen size has become larger than an initial screen size are enlarged, and the maps in the screens which have become smaller than the initial screen size are reduced in scale in accordance with the reduction in screen size, while maintaining the geographical range of the maps displayed in the display window prior to the boundary line being moved.
