Description

  The present invention relates to a navigation device that displays an icon such as a mark on a map, and more particularly, to a navigation device that can set a specific place as a destination, waypoint, or registered place by using the icon.

As a conventional navigation apparatus, a GPS (Global Positioning System) satellite is used to determine its own position and moving speed in real time. This type of navigation device is widely used as a mobile object such as an automobile or portable.
As a form of this navigation device, a map is displayed on a monitor based on the digitized map data, and its own position is shown on the map. In addition, the user has a function of guiding travel based on the set route by designating a departure point, a destination, a waypoint, and the like.

As this type of navigation device, the techniques of Patent Document 1 and Patent Document 2 are known.
Patent Document 1 discloses a display monitor provided with a touch panel, storage means for storing map data and facility data, a map on the display monitor based on the map data, and the map based on the facility data. And a display control means for displaying the facility mark in an overlapping manner, and an execution means for executing a process defined in the facility mark when the facility mark is pressed.

And making it easier to find a point or facility image on the map after scale switching.

JP 2008-180575 A JP2007-156866A

As described above, when the facility mark to be set by drag-and-drop is close to another facility mark, the technique of Patent Document 1 is a facility to be set by drag-and-drop in a direction not overlapping with another facility mark. Since the mark is enlarged and displayed, and the facility mark is displayed on the map, the operator can notice the presence of a plurality of facility marks depending on the overlapping state.
Moreover, the technique of patent document 2 makes the point or facility image on the map displayed with the display coordinates corresponding to the contact coordinates detected before the scale switching on the display made of the touch panel the same or substantially the same before and after the scale switching. The point or facility image on the map is made easy to find the point or facility on the map by returning the image after switching the scale.

  However, for example, when setting a destination or waypoint, when setting a specific icon to a specific position by drag and drop, if a similar facility exists near the destination, the facility mark of Patent Document 1 is expanded. It is not possible to cope with the display method. Further, since Patent Document 2 switches the scale around the destination according to the drag-and-drop distance with respect to the touch panel, a specific icon can be dragged and dropped when setting the destination or waypoint. It cannot respond to information near the destination to be set.

  Therefore, in the present invention, when setting a destination or waypoint, a registered location, etc. by dragging and dropping a specific icon, if there is a confusing location on the map in the setting location, the icon drop position is determined. It is a first object to provide a navigation device that can change the scale of a map displayed on a display to a small map and definitely perform the setting. In addition, when setting a destination or waypoint, registration location, etc. by dragging and dropping a specific icon, if the icon already exists at the setting location and there is a possibility that the icons overlap, the display is displayed. A second problem is to provide a navigation device that can change the scale of a map to a detailed map and perform the setting without fail.

In the case of a pen tablet, it can be operated by specifying the position between two points, and the mouse is operated in the same way as a touch pad. The drag and drop is a state where the icon is superimposed on the icon, for example, by pressing the mouse button, moving the mouse as it is, and releasing the mouse button at another location, thereby virtually removing the icon. This means an operation of “dragging” and “dropping” to another place. In addition, the above icons are made up of figures symbolized by attributes displayed on the display, such as map marks and other marks (trademarks) such as combination names (Lawson, Seven-Eleven (both are trademarks)), etc. It is included in the concept.
The drag of the drag-and-drop unit selects a specific icon from a plurality of icons, and the drop sets a specific icon selected from the plurality of icons by the drag at a specific location on the map. Thus, a series of drag and drop functions are constituted by the drag and the drop. The location included in the attribute category of the icon means a point that can be set as a destination of a navigation function on a map such as facilities, roads, intersections, stores, hospitals, and supermarkets.
Further, the map enlargement adjusting unit displays the map in a specific enlarged display before the drag and drop. Of course, even when the map is variable to a specific enlarged display, the map is stopped at the maximum enlargement rate of the existing map data.
Furthermore, when the icon is dropped in the enlarged map display by the map enlargement adjusting unit, the scale restoration unit returns to the original map scale before the map enlargement display and displays the map.

In the navigation device according to the second aspect of the present invention, the drag-and-drop unit selects a specific icon from a plurality of icons for each attribute displayed on the display, and the selected specific icon is displayed on the display. When an icon is set at a specific position on the map when moving to a desired position on the map, if there are a plurality of icons at the specific map position to be dropped, In the enlarged map display, the icon is dropped and the icon is set in the enlarged map display by the map enlargement setting unit.
Here, the drag-and-drop unit is one of a touch pad, a pen tablet, and a mouse. In the case of a touch pad, the display surface is formed as a touch switch, and the display surface slides. In the case of a pen tablet, it can be operated by specifying the position between two points, and the mouse is operated in the same way as a touch pad. The drag and drop is a state where the icon is superimposed on the icon, for example, by pressing the mouse button, moving the mouse as it is, and releasing the mouse button at another location, thereby virtually removing the icon. This means an operation of “dragging” and “dropping” to another place. In addition, the above icons are made up of figures symbolized by attributes displayed on the display, such as map marks and other marks (trademarks) such as combination names (Lawson, Seven-Eleven (both are trademarks)), etc. It is included in the concept.
The drag of the drag-and-drop unit selects a specific icon from a plurality of icons, and the drop sets a specific icon selected from the plurality of icons by the drag at a specific location on the map. Thus, a series of drag and drop functions are constituted by the drag and the drop. The location included in the attribute category of the icon means a point that can be set as a destination of a navigation function on a map such as facilities, roads, intersections, stores, hospitals, and supermarkets.
Further, the map enlargement setting unit displays an enlarged display so that the icons do not overlap if there is one or more icons at the remaining position on the map before the drag and drop. Is set as Of course, the enlarged display of the map is stopped at the maximum enlargement rate of the existing map data. The map enlargement setting unit is not functionally different from the map enlargement adjustment unit, but the map enlargement setting unit sets an enlargement ratio so that the icons do not overlap. The map enlargement adjusting unit enlarges and displays the icon by stopping after the icon is moved.

These icons are stored in the icon storage unit 91 together with points on the map 34 in association with attributes. In addition, the user can change the icon or create an original icon as his / her icon and associate it with a specific icon.
In particular, the icon according to the first embodiment is composed of a figure symbolized for each attribute displayed on the display, but a map mark such as a combination name (Lawson, Seven-Eleven (both are trademarks)), etc. The mark (trademark) etc. are also included in the concept.

In the first embodiment, an icon string storage unit 92 is provided. The icon string storage unit 92 is a memory area for storing icons that are likely to be used by the user, and is an area for storing icons to be dragged. When the present invention is implemented, an icon may be dragged directly from the icon storage unit 91. However, a frequently used item may be stored in the icon string storage unit 92 and used as in the first embodiment. it can.
In particular, when the frequently used icon is stored in the icon string storage unit 92 and used as in the first embodiment, for example, only one column is used as the icon string storage unit 92. Since no information overlaps the space map 34, the map 34 can be easily confirmed.

The icons stored in the icon storage unit 91 are distinguished by attribute categories. Further, the attribute information includes information such as a store, facility name, address, business hours, closed days, telephone number, presence / absence of a parking lot, the number of parking spaces, and a photograph of a building in the attribute information storage unit 93. Stored. Among the attribute information, information stored in the map information DB 84 is used for information such as large facilities, roads, and intersections. In particular, when setting an icon, if another icon already exists, it is possible to confirm whether the occupant has moved into the store or has changed.
The drag-and-drop storage unit 94 stores the dragged icon and the scale of the map, the attribute of the icon, and stores the drop position and the drop position. When the icon to be set is a destination or waypoint, it is confirmed by dropping and displayed on the screen of the display 3.

Further, the map enlargement adjustment unit 95 controls enlargement display of the map displayed on the display 3 or reduction display to return to the original, and the distance display is 2 km or more based on the center of the display 3 and the 1 km distance Display (1 / 160,000), 500m distance display (1 / 50,000), 200m distance display (1/2000), 100m distance display (1 / 10,000), 50m distance display (1/5000), 25m distance display (1/2500) can be set in stages. Therefore, when the distance display uses the 200 m distance display (1/20000), the display is changed in stages from 100 m distance display, 50 m distance display, and 25 m distance display. Of course, in places where there is no map data, there are places that cannot be changed. It is also possible to make a continuous change by interpolation of image data. Even in a city map, depending on the location, there may be no 50 m distance display (1/5000) or 25 m distance display (1/2500).
The scale restoration unit 96 has a function of returning to the map scale when the icon to be dragged and dropped is dragged.

Next, the control of the navigation apparatus according to the first embodiment processed by the calculation / control unit 1 will be described together with the screen display of the display 3.

FIG. 5 is an explanatory diagram of an icon sequence creation screen of the navigation device of the first embodiment, and FIG. 6 is an icon scroll of another example of the navigation device of the first embodiment. FIG. 7 is a flowchart of the first half of the “destination / intermediate location setting routine” of the navigation device of the first embodiment, and FIG. 8 is a flowchart of the second half. FIG. 9 is an explanatory diagram of a destination / route point setting screen of the navigation device of the first embodiment, FIG. 10 is an explanatory diagram of a drag and drop operation screen of the navigation device of the first embodiment, and FIG. FIG. 12 is an explanatory diagram of an enlarged screen of the navigation device according to the first embodiment of the present invention, and FIG. 13 is a destination of the navigation device according to the first embodiment. -It is explanatory drawing of the input screen of a waypoint.

  FIG. 2 shows a navigation apparatus according to Embodiment 1 of the present invention in which a main menu screen is displayed on the display 3 by executing a main program (not shown). By selecting various settings 22 from the main menu screen, various setting screens shown in FIG. 3 are displayed. Here, when the icon sequence creation 23 is selected, a program of “icon sequence creation routine” is executed. When the destination / waypoint setting 24 is selected, a “destination / waypoint setting routine” program is executed.

FIG. 4 is a flowchart of the “icon string creation routine” of the navigation device of the first embodiment, which is called during execution of the main program of the navigation device.
First, in step S11, as shown in FIG. 5, one icon row 31 is displayed at the top of the display 3. The icon row 31 is not limited to one row, and may be two or more rows. However, since the field of view of the map 34 to be used is limited to that extent, it is desirable to set it to 2 columns or less, preferably 1 column.

  Below the icon column 31 shown in FIG. 5, icons such as bookstores, schools, parks, shrines, etc., are divided as attribute categories, and bookstores, schools, parks, shrines, etc. are representative of the attributes. And all icons are displayed on the icon display unit 30 by scrolling. Of course, when the present invention is implemented, all icons with comments may be displayed on the icon display unit 30. However, since the user who is set first is not a person who is familiar with the concept of the icon type and the attribute, in the first embodiment, the icon is set so that even the first user can grasp the concept of the attribute. All icons are displayed together with the concept by operating the scroll unit 39 on the display unit 30 so that the icon and the concept can be understood.

  An erase key 32 is provided at the bottom of the display 3. That is, by dragging and dropping the icon in the icon row 31 to the delete key 32, an unnecessary icon in the icon row 31 can be erased (returned from the icon row 31 to the icon display unit 30). Of course, it may be deleted sequentially when one or two of the icon rows 31 are saturated. However, in the first embodiment, the use of the icon row 31 is reduced as much as possible, and the display of the map 34 as a background is displayed. The screen is not disturbed. Here, formally, by dragging and dropping the icon in the icon row 31 to the erasure key 32, unnecessary icons in the icon row 31 are erased, but the erased icon is stored in the icon row storage unit 92 as an icon. It will move to the storage unit 91.

  When a specific icon is dragged from the icon display unit 30 where all icons are displayed in step S12 and dropped in the icon row 31 in step S13, the icon moves to the icon row 31. That is, when the icons 31a, 31b, and 31c that are frequently used are sequentially selected in step S14, they are arranged in the icon row 31. When the end area 33 is selected in step S15, the operation of adding an icon to the icon row 31 is completed. If the end area 33 is not selected in step S15, the routine from step S11 to step S15 is repeatedly executed.

  Further, when it is determined in step S16 that the specific icon in the icon row 31 has been dragged without dragging the specific icon from the icon display unit 30 in which all the icons are displayed in step S12, it is determined in step S16. When it is determined in step S17 that the key has been dropped on the delete key 32, the corresponding icon is deleted from the icon row 31 in step S18, the space of the corresponding icon deleted from the icon row 31 is deleted in step S19, and the step When the end key 33 is selected in S20, the operation of deleting the icons in the icon row 31 is completed. If the end key 33 is not selected in step S20, the routine from step S11 to step S12 and from step S16 to step S20 is repeatedly executed.

  In this way, the icons stored in the icon storage unit 91 can be used with good operability by storing the icons to be used in particular in the icon string storage unit 92. The icon string storage unit 92 may store one icon or two or more icons of the icon string 31 to be stored.

In the navigation device of the first embodiment, the method of creating the icon sequence 31 from the icon storage unit 91 to the icon sequence storage unit 92 using the “icon sequence creation routine” of FIG. 4 has been described. However, as shown in FIG. 6, the icons stored in the icon storage unit 91 can be arranged in an upper row and all icons stored in the icon storage unit 91 can be displayed by left and right scrolling.
Further, the icons stored in the icon storage unit 91 can be arranged in a line along the left or right side, and all icons stored in the icon storage unit 91 can be displayed by scrolling up and down. The drag-and-drop is not different from that in which the icon string 31 is created by the icon string storage unit 92 from the icon storage unit 91, and the description thereof is omitted.

Next, the control of the navigation apparatus according to the first embodiment processed by the calculation / control unit 1 will be described together with the screen display of the display 3.
7 and 8 are flowcharts of the “destination / intermediate point setting routine” of the navigation device of the first embodiment, which are called during the execution of the main program of the navigation device.
In step S31, the current position is displayed. In step S32, the scale is reduced to a predetermined scale. In step S33, the target map 34 having a predetermined scale is scrolled as necessary to be displayed on the display 3. In step S34, the icon string 31 is superimposed.

  In step S34, the screen display shown in FIG. 9 is displayed. That is, the icon column 31 displays icons of bookstores, schools, and parks selected and registered by the user. On the display 3, an icon row 31 is superimposed on the display of the map 34 on the entire surface. The illustrated icon row 31 includes three icons. Specifically, the number of icons registered by the user is displayed.

  In step S35, a specific icon, for example, a bookstore icon, is dragged with a fingertip to select it from the icon row 31, and the operator attempts to drop it on the place considered as the destination in step S45 as shown in FIG. . That is, in step S35, an icon in the icon row 31 is selected, and in step S45, drag and drop is performed to drop it on a specific place.

  More specifically, when a specific icon, for example, a bookstore icon, is dragged with a fingertip in step S35 to select a bookstore icon, the drag position and the scale of the map 34 are stored in step S36. In step S37, it is determined whether or not the movement of the icon includes a component in the horizontal direction (horizontal direction) of the display 3 in a vector manner. If the horizontal component is not included, the process enters step S40. If a horizontal component is included, it is determined in step S38 whether or not the horizontal center (line XX in FIG. 10) has been passed. When it is confirmed that the center of the horizontal direction (line XX in FIG. 10) has been passed, in the step S39, the moving direction of the icon is the same as the moving speed of the icon or slightly slower than the moving speed. Scroll the map to.

  In step S40, it is determined whether or not the movement of the icon includes a vertical component (vertical direction) of the display 3. This determination is made based on whether or not the movement of the icon has a vector vertical component. If the vertical component is not included, the process enters step S43. If a vertical component is included, it is determined in step S41 whether or not the vertical center (line YY in FIG. 10) has been passed. When it is confirmed that the center of the vertical direction (line YY in FIG. 10) has been passed, the map is scrolled in the opposite direction at a speed slightly slower than the moving speed of the icon with respect to the moving direction of the icon in step S42. . That is, in steps S37 to S42, the moving direction of the dragged icon is determined, and when the left and right center (line YY in FIG. 10) and / or the vertical center (line XX in FIG. 10) is exceeded. In this case, the map side is moved to the center Z of the map to be enlarged.

  When the movement of the icon is stopped in step S43, in step S44, the cursor is set so that the stop position of the icon is the left and right center (line YY in FIG. 10) and the top and bottom center (line XX in FIG. 10). The icon is moved to the center Z, and the drop of the icon is determined in step S45. If there is a drop, the process enters step S50. When no icon is dropped in step S45, that is, when the illustrated bookstore icon 31a is moved with a finger, the icon 31a is hidden by the finger, and the exact position is unknown. Moreover, in the intersection, it may be unclear which point the operator intends.

  Therefore, when there is no icon drop in step S45, the elapse of the timer T after the icon is stopped in step S46, that is, the elapse of t seconds is determined. If the elapse of t seconds is determined, the process proceeds to step S47. It is determined whether or not the enlargement rate of the map is maximized. If not, the enlargement operation is performed in the message field 38 in step S48 as shown in FIG. The map is enlarged by one step, the timer T is cleared in step S49, and the routine from step S45 is repeated. When the icon is dropped in step S45, the process of step S50 is entered.

That is, if the icon drop is not confirmed in step S45 and the state where the icon is not dropped for a predetermined time is continued, the map enlargement ratio is increased by repeating the routine of steps S45 to S49 according to the time. That is, as shown in FIG. 12, the icon is moved, the map is enlarged around the stopped position, and accurate positioning is performed for setting the bookstore icon 31a. Of course, if the map to which the bookstore icon 31a is dropped from the beginning is enlarged to the maximum, it is judged in step S47, and the icon drop is awaited in a state where there is no map enlargement change.
Therefore, the icon is set as the destination even if the scales of 500m distance display (1 / 50,000), 200m distance display (1/2000), and 100m distance display (1 / 10,000) in the normal use state are used. If the map data is prepared, the map can be changed to a map of 50 m distance display (1/5000) and 25 m distance display (1/2500), and the place can be set in a specified state. it can.

In step S50, “Destination” or “Via” is set on the selection screen display 36 as shown in FIG. 13, and the input is awaited. When “route” is selected, an icon is set at the position dropped at the route at step S51. When “destination” is selected at step S50, an icon is set at the position dropped at the destination at step S52. To do.
In step S53, the map scale stored in step S36 is restored, and this routine is terminated.
[Embodiment 2]

FIG. 14 is a flowchart of the latter half of the “destination / intermediate point setting routine” of the navigation device of the second embodiment, and shows the operation of the latter half after finishing the first half routine of the first embodiment of FIG. It is. The routine from step S31 to step S44 of the control program of FIG. 7 is basically the same. FIG. 15 is an explanatory diagram of a setting / cancellation input screen of the navigation device of the second embodiment.
Since the difference between the first embodiment and the second embodiment is only in the control program, only the difference will be described here.

In step S44, the stop position is moved to the center Z of the display 3. In step S145, a drop operation is determined. If a drop operation is determined in step S145, whether there is another icon at the icon drop position in step S146. Determine whether. Note that the icon position and the overlap of icons in the present embodiment specify the position of the icon based on the range of the creation area where the icon is created, and specify the overlap of the icons. Therefore, it is different from the fact that the figures match and the center of the icon match, but in reality, the figure matches and the icon center may match.
If there is another icon area at the icon drop position, it is determined in step S147 whether or not the map enlargement ratio is maximum. If the map enlargement ratio is not maximum, the map is displayed in step S148. In step S149, it is determined whether or not duplication that another icon area exists at the icon drop position can be avoided.

  When it is possible to avoid duplication that another icon area exists at the icon drop position in step S149, a selection screen is displayed as shown in FIG. 13 for setting “destination” or “route” in step S150. The display 36 waits for the input, and when “route” is selected, an icon is set at the position dropped at the route in step S151. When “destination” is selected in step S150, in step S152. Set an icon at the location where it was dropped at the destination.

  Even if it is determined in step S147 that the map enlargement ratio is maximum, a message stating that icon duplication cannot be avoided in step S153 is displayed in the message field 37 as shown in FIG. "Is it?" And prompts the operator to select whether to "cancel" or "set". When “cancel” is selected in step S154, drag and drop is canceled in step S155. However, if cancel is not selected in step S154 and “set” is selected, the processes in and after step S150 are performed.

That is, in step S150, whether to set "Destination" or "Via-point" is performed on the selection screen display 36 as shown in FIG. When “route” is selected, an icon is set at the position dropped at the route at step S151. When “destination” is selected at step S150, an icon is set at the position dropped at the destination at step S152. To do.
In step S153, the map scale stored in step S36 is restored, and this routine is terminated.

  In the present embodiment, when it is shown in step S146 that the icon area overlaps with another icon area, the attribute information of the icon existing from the attribute information storage unit 93, that is, the name (name) is displayed. ), Address, telephone number, business hours, holidays, etc. can also be displayed. By displaying the attribute information in this way, it is possible to grasp information regarding whether or not another store or facility in the vicinity where the icon is dropped has been renamed, and setting without error is possible. Furthermore, the information of the icon which exists with a telephone number can be confirmed.

In the navigation device of the present embodiment, the method of enlarging the map 34 by one step in step S48 or step S148 has been described. However, when the present invention is implemented, the resolution (pixel / cm) between the maps 34 having different scales is set. By changing, it is possible to continuously change and interpolate the apparent scale.
Further, in the present embodiment, when the dragged icon moves, the one that moves greatly passes through the center on the left and right (line YY in FIG. 10) or the center on the top and bottom (line XX in FIG. 10). When the icon is stopped, the scrolling is performed when the icon stops moving. However, the routine from step S37 to step S42 can be omitted, and an enlargement operation can be performed from the center Z, and in the case of enlargement, it can be locked even if a finger or the like is released from the icon. The routine from step S37 to step S42 may be omitted, and the position of the icon to be dropped may be enlarged centering on the icon carried with the finger.

  In the navigation device according to the first embodiment and the second embodiment, the icons used by the “icon string creation routine” shown in FIG. 4 are picked up from all the icons stored in the icon storage section 91 and the icon string storage section. However, in the case of implementing the present invention, as shown in FIG. 6, the user directly drags from the icon storage unit 91 and moves it to a desired position on the map 34. You may drop it. At this time, it is more efficient to display all icons in a lump than the scroll function, but it is desirable that the icons and comments of the attributes move by scrolling so that selection errors do not occur.

  As described above, the navigation device of the above embodiment selects a specific one of the icons 31a to 31g from the plurality of icons 31a to 31g for each attribute displayed on the display 3, and selects the selected specification. Is moved to a desired position on the map 34 displayed on the display 3, a position on the map 34 is specified, and a drag-and-drop unit comprising steps S35 and S45 set by dropping, and the drag-and-drop A map enlargement adjusting unit comprising steps S45 to S49 for sequentially displaying an enlarged map in accordance with the time that the icon stays on the map when the movement of the icon stays for a predetermined time before dropping by the part, and the map enlargement One of the icons 31a to 31g is dropped in the enlarged map display by the adjustment unit. And time, and a scale restoring unit consisting of the step S53 to return to the map enlargement display before the original map display.

  The navigation device of the first embodiment selects a specific icon from the plurality of icons 31a to 31g for each attribute displayed on the display 3 by the drag and drop unit including step S35 and step S45, and selects the selected specific The icon is moved to a desired position on the map 34 displayed on the display 3, the position on the map 34 is specified, and set by dropping. At this time, when it is determined that the user has stayed for a predetermined time in step S46 without dropping at the position specified by the drag-and-drop unit comprising step S35 and step S45, the map enlargement adjustment unit comprising step S45 to step S49 is performed. Depending on the staying time, an enlarged map is displayed sequentially or step by step, and an icon composed of one of the icons 31a to 31g is dropped in the enlarged map display by the map enlargement adjusting unit comprising steps S45 to S49. The map is restored to the original map display before the enlarged map display by the scale restoration unit consisting of step S53.

  Therefore, when dropping an icon consisting of one of the icons 31a to 31g, if there is an adjacent facility or the road or the position of the road slightly away from the intersection by the selection of the intersection, the destination or waypoint In such a case, if the facility icon or the road icon is to be dragged and dropped, there is a possibility that the position cannot be clearly set, for example, on a map of 500 m distance display, 200 m distance display, and 100 m distance display. However, by dropping the icon movement for a predetermined time before dropping the icon consisting of one of the icons 31a to 31g, the map is enlarged (one or more steps), and the icon 31a to 31g is placed at a predetermined desired position. The icon which consists of one of can be put. Then, after dropping the icon, you can return to the previous map scale.

  Therefore, when a specific icon consisting of one of the icons 31a to 31g is set by drag and drop, for example, as a destination or waypoint, etc., there is a place that is confused with an attribute location corresponding to the set location Until the icon drop position is determined, the scale of the map 34 displayed on the display 3 can be changed to a small map, and the destination can be definitely set.

  The navigation device of the second embodiment selects one of the specific icons 31a to 31g from the plurality of icons 31a to 31g for each attribute displayed on the display 3, and displays the selected specific icon. 3 is moved to a desired position on the map 34 displayed on the map 3, a position on the map 34 is specified, and a drag and drop unit comprising steps S35 and S145 set by dropping, and the drag and drop unit at step S145. If one or more icons already exist at the position on the map 34 to be dropped before dropping in step S146, the map enlargement setting consisting of steps S146 to S149 is performed to display an enlarged map in which no overlapping occurs. And the enlarged map display by the map enlargement setting unit When the icon is dropped consisting of one of the icons 31a to 31 g, comprising a scale restoring unit consisting of steps S153 to return to the original display map before the map enlarged.

  The navigation device of the second embodiment selects a specific icon from the plurality of icons 31a to 31g for each attribute displayed on the display 3 by the drag and drop unit including step S35 and step S145, and selects the selected specific item. The icon is moved to a desired position on the map 34 displayed on the display 3, and the position on the map 34 is specified and set by dropping. At this time, if there is one or more icons at the position to be dropped on the map 34 before dropping to the position specified by the drag and drop unit consisting of step S35 and step S145, from step S146 to step S149. The map enlargement setting unit displays an enlarged map that does not overlap with the existing icon, and the map enlargement display by the map enlargement adjustment unit drops one of the icons 31a to 31g. In this case, the scale restoration unit in step S153 returns the original map display before the map enlarged display.

Therefore, when dropping an icon consisting of one of the icons 31a to 31g, if there is a facility that is displayed as an icon adjacent to the map, the map of 500m distance display, 200m distance display, and 100m distance display is accurate. Position setting may not be possible. However, before dropping the icon, the map is enlarged (one or more steps) so that the icons do not overlap, and the icon can be set at a predetermined desired position. And after dropping an icon by step S153, it can return to the reduced scale of the map so far.
Therefore, when a specific icon consisting of one of the icons 31a to 31g is set as a destination or waypoint by drag and drop, for example, there is a place that is confused with an icon having an attribute corresponding to the set place. Until the icon drop position is determined, the map 34 displayed on the display 3 can be scaled down to a detailed map, and the destination can be definitely set.

  The enlarged map display in the map enlargement adjusting unit comprising steps S45 to S49 or the map enlargement setting unit comprising steps S146 to S149 detects the moving direction of the dragged icon comprising one of the icons 31a to 31g. Then, scrolling is performed so that the drop position becomes the center Z position of the display 3, and an enlarged map is displayed around the center Z position of the display 3. Therefore, since the map is always enlarged from the center Z, the map is easy to see and the operation is easy to handle.

  The enlarged map display in the map enlargement adjusting unit consisting of step S45 to step S49 or the map enlargement setting unit consisting of step S146 to step S149 performs an enlarged map display so that the drop position becomes the center Z position of the display 3. . Therefore, even if the icon is dragged, there is a possibility of leaving the fingertip while moving to the target position. Therefore, the dragged icon composed of one of the icons 31a to 31g changes one or more of color, blinking, and shape until dropping. Accordingly, since one or more of the color, blinking, and shape of the icon are changed, it can be easily told to the operator that the changed state is before the drop, and the drop position is the center Z position of the display 3. Scrolling can be performed to improve the operability.

The enlarged map display in the map enlargement adjusting unit comprising step S45 to step S49 or the map enlargement setting unit comprising step S146 to step S149 is an enlarged map display centered on the position staying at the predetermined time when staying at the drop position for a predetermined time. Therefore, it is possible to enlarge the operation position as a center and to perform an operation with no sense of incongruity.
Further, the enlarged map display in the map enlargement adjusting unit comprising steps S45 to S49 or the map enlargement setting unit comprising steps S146 to S149 outputs a message as shown in FIG. Therefore, before the icon is dropped, the operator can understand the necessity of the enlarged display by giving a message to enlarge the displayed map.

  In this embodiment, the example of navigation destination setting and waypoint setting has been described. However, when implementing the present invention, a new icon is set on the map and stored as a registered location. It can also be used for searching.
