PROBLEM TO BE SOLVED: To provide a map drawing device capable of adjusting a processing load applied on drawing according to current processing resources.SOLUTION: A map drawing device 10 generates a drawing object from drawing object data and outputs the drawing object to a display unit. The map drawing device 10 comprises: a simplicity level setting unit 5 for setting a simplicity level indicating the degree of display simplicity to at least a partial area on a display screen of the display unit so that the simplicity level changes continuously or discontinuously in one of increasing and decreasing directions from one end toward the other end of the area; and a drawing object generation unit 6 for generating, from the drawing object data, the drawing object simplified according to a display position on the display screen, and for outputting the drawing object to the display unit. The simplicity level setting unit 5 changes a mode of continuous change or a border of discontinuous change according to change in a predetermined parameter. |
