Abstract

A circular contour is drawn by hand so as to surround icons 21a through 21f that are crowded together. As a result, a circle 32 is drawn upon a display monitor 16 at almost the same position and of almost the same size as the circle that was drawn by hand. The user presses a position on the circumference of this circle 32. As a result, among the icons 21a through 21f that are crowded together, only the icons 21b, 21d, and 21f that are shifting in the direction from the center of the circle 32 towards the position of pressing are displayed.

Claims

1. A map display device, comprising:

a map display control unit that displays a map upon a display monitor;

an icon display control unit that displays a plurality of shifting subjects as icons upon a map;

an icon designation unit that designates, from among the plurality of icons being displayed, a plurality of icons that are crowded together; and

a shift direction designation unit that designates a shift direction of icons to be searched for;

wherein

the icon display control unit displays, among the icons designated by the icon designation unit, those icons that are shifting in approximately the same direction as the shift direction designated by the shift direction designation unit.

2. A map display device according to claim 1, wherein the shifting subjects are related to weather.

3. A map display device according to claim 1, wherein:

the display monitor comprises a touch panel; and

the icon designation unit designates icons that have been surrounded by a contour drawn while the touch panel is being pressed.

4. A map display device according to claim 3, further comprising a circular contour display control unit that displays a circular contour over the map, on the basis of the contour drawn while the touch panel is being pressed;

wherein

the shift direction designation unit designates the shift direction on the basis of a position upon the circumference of the circular contour that is pressed.

5. A map display device according to claim 4, wherein the map display control unit changes the scale of the map displayed upon the display monitor on the basis of the circular contour.

6. A map display device according to claim 4, further comprising an icon selection unit that selects a plurality of specified icons from among a plurality of icons displayed within the circular contour;

wherein

the map display control unit changes the scale of the map so that the selected plurality of icons do not overlap one another.

7. A map display device according to claim 6, wherein the icon selection unit selects, from among the plurality of icons designated by the icon designation unit that are crowded together, those icons that overlap a contour drawn while the touch panel is being pressed.
