  Next, in FIG. 2B, when the user performs a determination operation on the cursor 41 using the input operation unit 15 (for example, a touch operation of the cursor 41 on the touch panel), as shown in FIG. The landmark selection unit 34 selects the landmarks 2 of the stand A and the stand B displayed in the region R within a predetermined range around the cursor 41 surrounded by the broken line frame in the drawing as the target landmark.

  Then, when the target landmark is selected in this way, as shown in FIG. 2 (c), it is automatically scrolled to the map 1 around the vehicle position shown in FIG. 2 (a). The landmark 2 displayed on the map 1 is limited to only the landmarks 2 of the stand A and the stand B as target landmarks under the control of the landmark drawing control unit 35.

  Since the map 1 on which the limited display is performed in this way has not only the visibility of the landmark 2 but also the visibility of the road 3 and the vehicle position mark 4 in the map 1, the user can It is possible to quickly and appropriately grasp the nearest stand A or stand B.

  As described above, according to the present embodiment, the landmark drawing control unit 35 controls the landmarks other than the landmark 2 of the same type as the landmark 2 selected in the display state of the map 1 by the landmark selection unit 34. Since the mark 2 can be hidden on the map 1, it can be switched to a display limited to the landmark desired by the user by a simple operation.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.

  For example, the present invention can be applied to a navigation device other than the in-vehicle navigation device.

  For example, after the determination operation for the cursor 41 shown in FIG. 2B is performed, the landmark selection unit 34, as shown in FIG. 3A, the landmark or target land of the same brand as the target landmark. You may make it display the operation screen 42 for selecting which limited display of the landmark of the same industry as a mark transfers.

  In this case, when the limited display of landmarks of the same brand is selected by the user operation using the input operation unit 15, the landmark drawing control unit 35 controls the display as shown in FIG. The same limited display may be performed. Further, when the limited display of landmarks of the same industry is selected, as shown in FIG. 3B, all landmarks of the same industry (gas station in FIG. 3) as the target landmark are displayed. What should I do?
