  The map information 200 includes POI information of various facilities such as convenience stores, department stores, hotels, gas stations, etc., as well as entrances and exits, and if necessary, POI icons can be displayed on the map. It is.

<Example of determining POI icon display area>
Here, for example, around the terminal station in the city center, there are many entrances to the subway and underground mall. For this reason, since many entrance / exit icons are displayed densely on the map of the navigation application, there is a problem that it is difficult to find an appropriate entrance / exit and visibility is lowered (for example, see FIG. 1).

  Therefore, the display control unit 102 of the map display server 1 according to the present embodiment determines a POI icon display area on which a POI icon is to be displayed on the map according to the searched route, and within the determined POI icon display area The POI icon located only at the position is drawn (arranged). On the other hand, POI icons located outside the POI icon display area (POI icon non-display area) are not drawn (arranged). Hereinafter, a determination example of the POI icon display area will be described.

(Example 1)
FIG. 6 is a diagram showing a determination example 1 of the POI icon display area according to the present embodiment. As shown in FIG. 6, a place along the searched route (a set of places can be called an area), for example, an area within a predetermined distance n from the searched route is set as a POI icon display area. Note that the predetermined distance n can be arbitrarily set, such as 10 m, 30 m, 50 m, and 100 m.

  First, reference is made to A1. In the case of A1, the POI icon display area (shaded area in the figure) is an area a1 within a predetermined distance n from the route from the departure point to the destination along the route.

  In the case of B1, the route from the starting point to the destination includes one section (for example, a corner). Therefore, the POI icon display area is an area b1 within a predetermined distance n from the route from the departure point to the first section and from the first section to the destination, along the route.

  In the case of C1, the route from the starting point to the destination includes two sections. Therefore, the POI icon display area is routed along the route from the first section to the first section, from the first section to the second section, and from the second section to the destination. Is a region c1 within a predetermined distance n.

  In the case of D1, the route from the starting point to the destination includes three sections. Therefore, the POI icon display area is along the route, the first section from the departure point, the second section from the first section, the third section from the second section, and This is a region d1 within a predetermined distance n from the route from the third section to the destination.

(Example 2)
FIG. 7 is a diagram showing a determination example 2 of the POI icon display area according to the present embodiment. As shown in FIG. 7, the area included in the route along the searched route, specifically, the line connecting the starting point and any of the sections or destinations, and the searched route The included area is a POI icon display area. When there is an area included in the route, there is at least one corner on the route. If there is no corner, no area is included in the path.

  First, reference is made to B2. In the case of B2, the route from the starting point to the destination includes one section (for example, a corner). However, in the case of B2, since the line connecting the starting point and the section (turning corner) does not form an area, the POI icon display area (the hatched area in the figure) includes a line connecting the starting point and the destination and a route (route line). ) To be included in the region b2.

  In the case of C2, the route from the starting point to the destination includes two sections. Therefore, in the case of C2, the POI icon display area is an area c2-1 included by the line connecting the departure point and the second section and the searched route. The POI icon display area is an area c2-2 that is included by a line connecting the starting point and the destination and the searched route. Furthermore, the POI icon display areas are an area c2-1 and an area c2-2.

  In the case of D2, the route from the starting point to the destination includes three sections. Therefore, in the case of D2, the POI icon display area is an area d2-1 included by the line connecting the departure point and the second section and the searched route. The POI icon display area is an area d2-2 that is included by a line connecting the starting point and the destination and the searched route. In addition, the POI icon display area is an area d2-3 included by a line connecting the departure point and the destination and the searched route. Furthermore, one POI icon display area is an area d2-1, an area d2-2, and an area d2-3 (including an overlapping area of the area d2-2 and the area d2-3).

  In the case of C2 of the second example, the POI icon display area is the area c2-1 and the area c2-2, or a combined area of these areas. In the case of D2 of Example 2, the POI icon display area is the area d2-1, the area d2-2, the area d2-3, or the sum area of these areas. In this way, when there are a plurality of areas that can be candidates for the POI icon display area, the administrator can appropriately adopt which area is to be adopted as the POI icon display area in accordance with the POI icon or the like.

  For example, it is assumed that the departure place is a terminal station in the city center and the POI icon is an entrance / exit icon. In general, the doorways are densely packed around the station, but there are not enough numbers or no longer exist at some distance from the station. Therefore, since the area d2-3 that is somewhat distant from the station (departure point) does not have many entrances, the administrator limits only the area around the station, such as the area d2-1 and the area d2-2. Thus, it can be adopted as a POI icon display area.

  On the other hand, it is assumed that the departure place is a terminal station in the city center and the POI icon is a convenience store icon. In general, convenience stores can be crowded around the station, but the convenience stores may still be crowded even if they are some distance from the station. Therefore, the administrator can employ the POI icon display area over a relatively wide range, such as the sum area of the area d2-1, the area d2-2, and the area d2-3.

(Example 3)
FIG. 8 is a diagram showing a determination example 3 of the POI icon display area according to the present embodiment. Example 3 is a combination of Example 1 and Example 2 described above.

  First, reference is made to B3. In the case of B3, the POI icon display area (shaded area in the figure) is the area b3 where the area a1 of Example 1 and the area b1 of Example 2 overlap.

  In the case of C3, the POI icon display area is an area b3 in which the area b1 in Example 1 overlaps the area c2-1 and area c2-2 in Example 2.

  In the case of D3, the POI icon display area is an area d3 in which the area d1 of Example 1 overlaps the areas d2-1, d2-2, and d2-3 of Example 2.

<POI icon display processing>
FIG. 9 is a flowchart showing an example of POI icon display processing on a map according to the present embodiment. Hereinafter, specific description will be given with appropriate drawings.

  S1: The route search unit 101 of the map display server 1 determines whether a route search request (route search request) has been received from the navigation application of the map display terminal 2. The route search request includes information on the departure place and the destination. If a route search request is received, the process proceeds to S2. On the other hand, when a route search request is not received, it waits until a route search request is received.

  FIG. 10 is a diagram illustrating an example of a route search screen according to the present embodiment. The user displays a route search screen on the navigation application of the map display terminal 2, inputs information such as a departure place and a destination, and presses “search”, whereby the departure place and the destination are displayed on the map display server 1. A route search request including the destination is transmitted.

  S2: When the route search unit 101 receives a route search request from the map display terminal 2, it executes route search processing. That is, the route search unit 101 searches for a route from the departure point to the destination based on the map information 200 in the storage unit 103.

  S3: The display control unit 102 executes a POI icon display area determination process in the map. Specifically, the POI icon display area is determined by the above-described determination example of the POI icon display area (see, for example, FIGS. 6 to 8).

  S4: Upon determining the POI icon display area, the display control unit 102 generates map information for responding to the map display terminal 2. Specifically, the route searched in S2 is drawn (arranged) on the map, and the POI icon located in the POI icon display area determined in S3 is drawn (arranged). A POI icon located outside the POI icon display area determined in S3 on the map is not drawn.

  S5: The display control unit 102 transmits the map information generated in S4 to the map display terminal 2. Thereafter, the navigation application of the map display terminal 2 displays the received map information on the display device 16.

(Supplement)
Note that the POI icon display or non-display control on the map may be activated only in a dense area of POI. For example, even if it is a terminal station in the center of a city, there are not many entrances and exits. Even if all the entrance and exit icons are displayed on the map, it is difficult to find an appropriate entrance or exit, and the visibility is reduced. Because there are few.

  Specifically, in the POI icon display area determination process in S3, the map display server 1 (display control unit 102) determines, for example, whether or not there is a predetermined number or more of POI information on the map, and the POI information. Only when a predetermined number or more exists, the POI icon display or non-display is controlled according to the searched route.

<Example of POI icon map display>
FIG. 11 is a diagram illustrating an example (part 1) of the map display according to the present embodiment. The POI icon display area in this example is an area c1 indicated by C1 in FIG.

  In the map information 200a shown in FIG. 11, a search route and an entrance / exit icon are displayed on the map. However, when compared with the map information of FIG. 1 or FIG. 5, it can be seen that the displayed entrance / exit icons are reduced on the map. Specifically, an entrance / exit icon is displayed only in a region (POI icon display region) within a predetermined distance n from the searched route along the searched route (route line). On the other hand, no entrance / exit icon is displayed in an area other than the area (POI icon non-display area).

  Note that the map information 200 shown in FIG. 11 can be displayed after “search” on the route search screen (FIG. 10), for example.

  FIG. 12 is a diagram illustrating an example (part 2) of the map display according to the present embodiment. The POI icon display area in this example is an area c2-1 and area c2-2 indicated by C2 in FIG.

  In the map information 200b shown in FIG. 12, it can be seen that the doorway icons displayed on the map are reduced as compared with the map information of FIG. 1 or FIG. Specifically, an entrance / exit icon is displayed only in an area included in the route along the searched route. On the other hand, no entrance / exit icon is displayed in an area other than the area (POI icon display area).

  As described above, only the entrance / exit icon corresponding to the searched route is displayed in the dense area of the entrance / exit on the navigation application of the map display terminal 2, so that the user can find the entrance / exit located at a convenient place when heading to the destination. Easy to find and easy to find. Also, visibility is improved. On the other hand, although the entrance / exit icon is not displayed in the POI icon non-display area, when the route search is performed, the user's interest is from the departure point to the destination and the surrounding area, and the entrance / exit icon that is completely away from the search route is Even if it is not displayed, there is little substantial inconvenience.

<Summary>
As described above, according to the map display system 100 according to the present embodiment, the POI icon to be displayed can be controlled according to the searched route. Thus, the user can easily find an appropriate entrance (exit / exit located at a convenient location) in a dense area of POI (eg, entrance / exit) on the map of the navigation application, and the visibility is improved.

  It should be noted that although the present invention has been described by way of preferred embodiments of the present invention with specific examples, these specific examples may be used without departing from the broad spirit and scope of the present invention as defined in the claims. Obviously, various modifications and changes can be made to the examples. In other words, the present invention should not be construed as being limited by the details of the specific examples and the accompanying drawings.

  For example, in the above-described embodiment, the map display system 100 including the map display server 1 and the map display terminal 2 has been described. However, for example, when the map display terminal 2 has the function of the map display server 1, the map display terminal 2 alone can provide the same effects as the map display system 100. Such a configuration can be effectively realized when the map display terminal 2 is a car navigation device, for example.

  In the above-described embodiment, the entrance / exit is taken up as an example of the POI information (POI icon). However, the POI information is not limited to the entrance / exit. For example, when the POI information is a convenience store, the user can easily find a convenience store located at a convenient place to drop in, such as on the way to the destination, by determining the convenience store to be displayed according to the searched route. .
