  Next, the operation of the map display control device NV according to the embodiment will be described with reference to FIGS. Note that the map display control process according to the embodiment shown by the flowchart shown in FIG. 3 is a process executed mainly by the map control unit 2. For example, an operation for displaying a map on the display D is executed in the operation unit 12. It starts from the timing.

  First, in the database DB, map data corresponding to a map to be displayed on the display D, node data of a node indicating a predetermined point on the road included in the map and displayed on the display D, and the node Link data corresponding to the roads connected to each other, position data indicating the positions of the features included in the map on the map, and the features used when displaying the features on the map The icon data corresponding to the icon or mark indicating is recorded in advance. In the following description, the icon or mark is simply referred to as “icon or the like”.

  Next, the line-of-sight camera 11 detects the line of sight of the user who operates the navigation device on which the map display control apparatus NV according to the embodiment is mounted and the arrival position (line-of-sight position), and displays the detection result as a display control unit. Output to 2.

On the other hand, the recommendation level data generation unit 10 generates recommendation level data according to an embodiment indicating the recommendation level in the presentation to the user of the features included in the map.
This recommendation level data corresponds to an example of “recommendation level information” according to the present application. At this time, the recommendation degree data has a value from “0” to “100”, for example, and is generated as a larger value as the recommendation degree to the user is higher. At this time, the recommendation degree data is, for example, history data such as features that are frequently visited in the normal action range of the user (the history data is recorded in advance in the database DB, for example), or the map display control device NV. Is generated by the recommendation degree data generation unit 10 based on data indicating the current position of the vehicle on which is mounted.

  And based on the request | requirement from the display control part 2, the interface 1 acquires the said recommendation degree data corresponding to the feature which should be displayed on the display D as a map from the recommendation degree data generation part 10 (FIG. 3 step S1). . Thereafter, a predetermined number (for example, four) of features are determined in descending order of the generated recommendation degree data. In addition to this, the interface 1 similarly acquires icon data for displaying an icon indicating the determined feature on the display D from the database DB based on a request from the display control unit 2. Then, the interface 1 outputs the acquired recommendation degree data and icon data to the display control unit 2.

  Accordingly, the display control unit 2 displays the map on the display D using map data corresponding to the map to be displayed on the display D and icon data indicating the features to be displayed on the display D together with the map. To do. At this time, the display control unit 2 controls the display mode of icons and the like based on the recommendation degree (step S2 in FIG. 3). Note that the map display control process in step S2 will be described later.

  Thereafter, the display control unit 2 determines whether or not to end the map display control process according to the embodiment, for example, by confirming whether or not an operation for ending displaying the map display on the display D has been executed in the operation unit 12. Determine (step S3). In the determination of step S3, when the map display control process ends, the display control unit 2 shifts to another process as the navigation device. On the other hand, when the map display control process according to the embodiment is continued in the determination of step S3 because there is another feature that has not yet displayed an icon or the like (step S3; NO), the map control unit 3 It returns to said step S1 in order to perform the map display control process which concerns on an Example about another feature.

  Next, the display control process for the icons and the like in step S2 will be described more specifically with reference to FIGS.

  First, it is assumed that the fact that the map MP illustrated in FIG. 4 is to be displayed on the display D is designated by an operation on an operation unit (not shown), for example. At this time, in the map MP, for example, an icon TU indicating the A rental video shop, an icon MA indicating the B hamburger shop, and an icon SB indicating the D coffee shop, the A rental video shop, the B hamburger shop, and the D coffee are displayed. It is displayed at a position on the map MP corresponding to the position of each store. In addition to this, although the feature is the C Gyudon store as a feature to be presented to the user based on the recommendation degree data, the position is the position indicated by the icon SK illustrated in FIG. It is assumed that it is outside the geographical range of the map displayed on the current display D.

  At this time, as shown in FIG. 5, for example, as shown in FIG. 5, the map control unit 2 sees the presence of the C Gyudon store to be recommended and the currently displayed map MP as the icon display control process in step S2 of FIG. An arrow-shaped marker AR indicating the direction to the (geographic) position of the C Gyudon store and an icon SK indicating the C Gyudon store are suitable for indicating the position of the C Gyudon store. Display in position. At this time, as an example of the “preferable position”, for example, when the map MP is traced in the direction indicated by the arrow of the marker AR, the actual position of the C Gyudon store indicated by the icon SK is reached. The display position of the marker AR is mentioned. Accordingly, the user who has seen the map MP illustrated in FIG. 5 recognizes that there is a recommended C beef bowl store if the user moves upward in the map MP, for example.

  Then, when the marker AR or the icon SK is selected by the operation in the operation unit 12, the map control unit 2 uses the C beef bowl store indicated by the icon SK as the map MP as the icon display control process in step S2. The map MP is scrolled or the scale of the map MP is changed so as to fall within the display range. As a result, in the case illustrated in FIG. 5, the result of changing the scale of the map MP so that the C Gyudon store is within the display range of the map MP is illustrated in FIG. 6. In FIG. 6, an icon SK indicating the C beef bowl store that was outside the display range of the map MP in the state of FIG. 5 is displayed within the display range. Further, at this time, the display control unit 2 deletes the marker AR and the (temporary) icon SK displayed at the stage of FIG. 5, and displays an icon at a position on the map MP corresponding to the actual position of the C Gyudon store. SK displays again.

  Here, the display control unit 2 continues the transition from the display state illustrated in FIG. 5 to the display state illustrated in FIG. 6, for example, when the selection operation of the marker AR or the icon SK by the operation unit 12 is continued. It may be configured to be performed, or may be configured to be performed only for a preset time after the selection. Then, after the display of the display state illustrated in FIG. 6 is completed, the display state illustrated in FIG. 5 may be returned to, or a transition may be made to another display state.

  Furthermore, the display control unit 2 displays the map MP in the display state illustrated in FIG. 5 only when the line-of-sight position detected by the line-of-sight camera 11 is on the display D as the icon display control process in step S2. You may comprise. In this case, when the line-of-sight position moves away from the display D, the map control unit 2 maps the displayed marker AR or icon SK at the time of the separation or after the elapse of a preset time from the timing. You may comprise so that it may erase from on MP.

  As described above, according to the map display control process according to the embodiment, the feature is displayed together with the map MP by display using an icon or the like, and the geographical display of the currently displayed map MP is displayed. When there is a recommended C Gyudon store to be presented outside the range, a marker AR indicating the presence and location of the C Gyudon store and an icon SK indicating the C Gyudon store are displayed. The user can easily recognize the presence or position of the C Gyudon restaurant that is outside the range of the displayed map but should be recommended.

  Further, when the marker AR or icon SK is selected by the operation unit 12, the map MP is updated so that the position of the C gyudon store corresponding to the selected marker AR or icon SK is within the display range (that is, , Scrolling or changing the scale), the geographical position of the C Gyudon store corresponding to the selected marker AR or the like can be displayed in a recognizable manner.

  Furthermore, when displaying the updated map MP (see FIG. 6) only during the period when the selection of the marker AR or the icon SK is continued, the map MP is updated only during the required period to The position can be confirmed.

  Furthermore, when the display of the marker AR and the icon SK is started when it is detected that the user's line-of-sight position is on the display D, the marker AR or the like can be displayed only when necessary.

  Further, when the line-of-sight position becomes a position other than the display D after the start of the display of the marker AR and the icon SK, when the display of the marker AR or the like is ended after the change of the line-of-sight position, only the period during which the user can visually recognize The marker AR and the like can be displayed.

[Modification]
Next, a modification corresponding to the above-described embodiment will be described.

(I) First Modification First, a first modification will be described with reference to FIG. FIG. 7 is a diagram illustrating a display example of icons and the like according to the first modification.

  As the first modified example, as illustrated in FIG. 7, the icon SK is displayed outside the display range of the map MP in the direction of the right turn from the intersection CR ahead of the current position of the vehicle indicated by the current position mark CP and Assume that there is a C Gyudon store, and that there is a B hamburger shop that is recommended by the icon MA and is outside the display range of the map MP in the direction turned left from the intersection CR. In this case, the display control unit 2 does not display the marker AR and the (temporary) icon SK according to the embodiment (see FIG. 5), but actually exists as the icon display control process in step S2 of FIG. Guide sign (a so-called blue signboard installed on the roadside of national roads, etc. More specifically, the Ministry of Land, Infrastructure, Transport and Tourism HP (URL: http://www.mlit.go.jp/road/sign/sign/douro/ road-sign.htm) etc.), which is an indication display KB that includes an icon MA and an icon SK instead of the place name in the guide sign, and is indicated by the icon MA and the icon SK, respectively. An instruction display KB including the direction of the location of the shop and C beef bowl as an arrow in the guide sign may be displayed on the display D. In this case, the rightward arrow and the leftward arrow in the instruction display KB illustrated in FIG. 7 correspond to the marker AR according to the embodiment (marker AR indicating B hamburger shop and C beef bowl respectively), respectively. In the case of this first modification, the direction of presence of icons MA, B hamburger shop, etc. is displayed in the same form as a well-known guide sign, so the presence or position of a feature to be recommended is known in a known form. Easy-to-understand display.

  In the first modification, the distance from the current position to the B hamburger shop etc. and the place name where the B hamburger shop etc. exist may be displayed in accordance with the instruction display KB. In this case, since the distance or place name corresponding to the position of the B hamburger shop or the like is displayed together with the instruction display KB, the presence or position of the feature to be recommended can be displayed more easily.

(II) Second Modified Example Next, as a second modified example, the display control unit 2 applies only the feature whose recommendation degree data (absolute value or relative value) acquired through the interface 1 is equal to or higher than a preset threshold value. It is good also as display objects, such as marker AR and an icon corresponding to a feature. In this case, since only features whose recommendation level data is equal to or higher than the predetermined threshold are displayed as markers AR and icons, even if the order of recommendation level is higher, the feature level of recommendation level is low. Is excluded from the display target of the marker AR or the like, and unnecessary display of the marker AR or the like can be prevented. Note that this processing may be applied only to features existing outside the display range of the map MP. More specifically, when the order of recommendation is set to display the top four features, and the geographical position of the feature is within the displayed map MP range, Even if the recommendation level data is equal to or less than a prescribed threshold value, an icon or the like indicating the feature can be displayed. On the other hand, if the order of recommendation level is the top four features and the geographical position of the feature is outside the range of the displayed map MP, the recommendation level data of the feature Can be excluded from the display target.

(III) Third Modification Next, as a third modification, the display control unit 2 displays a display mode (such as a shape, pattern, or color on the display) of an icon or the like indicating a feature located within the display range of the map MP. The same applies to the following), and the display mode of the icon or the like indicating the feature located outside the display range of the map MP displayed together with the marker AR is relatively different from each other so that the icon or the like is displayed on the display D. You may comprise. In this case, since the display mode such as the icon indicating the feature located within the display range of the map MP and the display mode such as the icon displayed together with the marker AR are displayed relatively differently, The feature outside the geographical range of the displayed map MP and the feature within the range can be distinguished and recognized.

(IV) Fourth Modification Finally, as a fourth modification, when there is an icon or the like indicating a feature to be displayed together with the marker AR, the display control unit 2 is an icon or the like indicating a feature located within the display range of the map MP. May be configured to be prohibited from being displayed. In this case, when there is an icon or the like to be displayed together with the marker AR, display of an icon or the like indicating a feature located within the display range of the map MP is prohibited, so that the marker AR and (temporary) icon or the like (FIG. 5) Display) can be displayed with improved visibility. In addition, when displaying the icon etc. which show the feature determined based on recommendation level data on map MP, the icon which shows the feature located in the display range in map MP which is not determined based on recommendation level data Such a display may be prohibited. More specifically, when the recommendation order is set to display the top four features, an icon or the like indicating the feature is displayed, and other features located within the display range of the map MP are displayed. Prohibits the display of object icons.

(V) Other Modifications As another modification , the scale of the map MP is not displayed so that the marker AR is displayed, but icons of features existing outside the display range of the currently displayed map are displayed. May be automatically changed, or the map MP may be automatically scrolled.

  Also, a program corresponding to the flowchart shown in FIG. 3 is recorded on a recording medium such as an optical disk or a hard disk, or obtained via a network such as the Internet, and read out to a general-purpose microcomputer or the like. By executing this, it is possible to cause the microcomputer or the like to function as the display control unit 2 according to the embodiment.
