However, as described above, the present invention is not limited thereto.

  FIG. 1 is a system configuration diagram of an information processing system 10 including an information processing apparatus 100 according to the present embodiment. As shown in FIG. 1, the information processing apparatus 100 and the terminal apparatus 200 are set to be communicable with each other via a network 400 such as the Internet or a dedicated line, thereby configuring a map display system. The network 400 is configured by a wireless network or a wired network. Examples of communication networks include mobile phone networks, PHS (Personal Handy-phone System) networks, wireless LAN (Local Area Network), 3G (3rd Generation), LTE (Long Term Evolution), 4G (4th GenerationMex), (Registered Trademark), infrared communication, Bluetooth (Registered Trademark), wired LAN, telephone line, power line network, IEEE 1394, and other networks.

  The terminal device 200 is an information processing device having a function of intermittently acquiring position information using, for example, a GPS (Global Positioning System) or the like and transmitting it to the information processing device 100 via the network 400. As illustrated in FIG. 1, the terminal device 200 displays a main control unit 220 including a CPU and a memory, a communication unit 240 for connecting to the network 400, an input unit 210 such as a touch panel that receives an operation from a user, and a screen. It is preferable to include a display unit 250, a positioning unit 260 that measures current position information, and the like.

  Specifically, the terminal device 200 includes a mobile phone (whether it is a so-called smart phone or a feature phone), a tablet, a notebook PC (Personal Computer), a PDA (Personal Data Assistance), a game machine, A car navigation device or the like is assumed, but is not limited thereto. For example, it may be a terminal device such as a desktop PC that does not have portability. It is desirable that the user can use the map display service by installing a map application (hereinafter referred to as a map application) in the terminal device 200. The map display service refers to a service provided by the information processing apparatus 100 that displays a map with an arbitrary latitude and longitude at an arbitrary scale for a user.

  Each configuration of the information processing apparatus 100 for realizing such a map display service will be described. As illustrated in FIG. 1, the information processing apparatus 100 includes an input unit 110, a control unit 120, a storage unit 130, a communication unit 140, and a display unit 150.

  The input unit 110 is configured to receive an operation from an administrator of the information processing apparatus 100, and can be realized by a keyboard, a mouse, a touch panel, or the like.

  The control unit 120 includes an arithmetic processing unit 121 such as a CPU or MPU, a memory 122 such as a RAM, and an image processing unit (not shown). The arithmetic processing unit 121 operates various functional units by executing a program recorded in the storage unit 130 based on various inputs. This program may be stored in a recording medium such as a CD-ROM, or distributed via the network 400 and installed in a computer. The memory 122 is for temporarily storing various types of data necessary for computation and the like during execution of processing in the server program and the program.

  The storage unit 130 is configured by a storage device such as a hard disk, and records various programs necessary for executing processing in the control unit 120, data necessary for executing the various programs, and the like. Although not shown in FIG. 1, for example, the storage unit 130 preferably includes map data, road network data, content data, and the like.

  Map information refers to information for drawing a map. For example, the map information includes a map image, latitude and longitude information, and the like. Road network data consists of road intersections, inflection points, end points, etc. as nodes, routes connecting each node as links, node data (node latitude and longitude), link data (link numbers), and all links The database includes link cost information data relating to cost information (distance and required time). Content data refers to information that is displayed superimposed on a map. For example, the content data includes event information, store information, facility information, traffic regulation information, icons, note information, and the like. The content data is preferably information associated with a mesh.

  A mesh refers to a plurality of divided areas obtained by dividing a map based on latitude and longitude. In the present embodiment, the mesh is described as a square area, but the present invention is not limited to this, and the shape and size of the mesh divided area can be appropriately set according to specifications and design. For example, the mesh shape can be a region surrounded by a polygon such as a quadrangle, a hexagon, or a rhombus, or a curve such as a circle. Moreover, the size of the mesh may not be constant. For example, when the user wants to specify a frequently staying mesh, the size of the mesh can be set large. On the other hand, when the user wants to specify a store or the like frequently visited, the mesh size can be set small. For example, the urban mesh may be made smaller (finer). In addition, the size of the mesh may be changed for each region according to demographic information (for example, the mesh in a region with a large population is made smaller), or the size may be set based on the classification of the municipality, the type of residential land, etc. .

  In the present embodiment, the storage unit 130 further includes a mesh size DB 131 and a priority DB 132. FIG. 2 is a diagram illustrating an example of the mesh size DB 131, and FIG. 3 is a diagram illustrating an example of the priority DB 132.

  As shown in FIG. 2, the mesh size DB 131 stores the scale on which the map is displayed and the mesh size in association with each other.

  In addition, as shown in FIG. 3, the priority DB 132 includes an ID of a facility such as a park, a building, or a road, a latitude and longitude of the facility, an ID of an icon for displaying the facility on a map, and a priority of the facility. Are stored in association with each other. Although not limited to this, in the following description, it is assumed that the facility is a tourist spot such as a shrine, a temple, or a park as an example.

  The priority is a value indicating a priority order in which icons corresponding to sightseeing spots are displayed on the map. It is desirable that the icon be displayed on a map with a smaller scale as the tourist spot has a higher priority. In the present embodiment, as an example, it is assumed that the priorities are three levels of 3, 2, and 1 in descending order. For example, a high-priority tourist spot may correspond to a high-profile tourist spot. Specifically, priority 3 may be given to major tourist spots, priority 2 may be given to semi-major tourist spots, and priority 1 may be given to minor tourist spots. In the following description, the priority is assumed to correspond to the name recognition, but is not limited thereto. For example, the priority may correspond to the number of customers or importance of the facility.

  Furthermore, as illustrated in FIG. 1, the arithmetic processing unit 121 preferably includes a reception unit 1211, a size determination unit 1212, a display level determination unit 1213, and a display control unit 1214 as functional units.

  The reception unit 1211 receives a map display request from the terminal device 200 in which the map application is installed. For example, it is desirable that the user operates the terminal device 200 to specify the latitude / longitude of the point to be displayed on the map and the scale of the map, and transmit the designation to the reception unit 1211. The accepting unit 1211 can determine the display range of the map to be displayed on the terminal device 200 based on the received latitude and longitude and the scale.

  The size determination unit 1212 determines the size of the mesh for dividing the map based on the scale of the map displayed on the display unit 250 of the terminal device 200. Specifically, the size determination unit 1212 refers to the size DB 131 and acquires the size of the mesh corresponding to the scale received by the reception unit 1211. For example, when the user specifies the map scale to be 1/25 thousand, the size determination unit 1212 uses a mesh size of 10 km × 10 km (hereinafter, 10 km × 10 km) as a “secondary mesh”. Can be obtained).

  The display level determination unit 1213 determines the display level for each of the meshes divided by the size determined by the size determination unit 1212 (hereinafter also referred to as “display mesh”). The display level indicates what priority priority sightseeing spot should be displayed for the mesh. In the present embodiment, description will be made assuming that three levels of A, B, and C are set in order from the highest display level. By the processing of the display control unit 1214 described later, the mesh corresponding to the higher display level is controlled so that the icon corresponding to the sightseeing spot with lower priority is less likely to be displayed.

  The display level determination unit 1213 preferably determines the display level based on the priority associated with the tourist spot in the mesh. Specifically, the display level determination unit 1213 can determine the display level of the display mesh based on the display level of the reference mesh included in the display mesh. The reference mesh is a reference mesh for determining the display level of the display mesh, and is, for example, a 1 km × 1 km mesh. The minimum mesh that can be displayed on the map may be used as the reference mesh.

First, the display level determination unit 1213 refers to the priority DB 132 and determines the display level of the reference mesh based on the highest priority among the tourist spot priorities included in the reference mesh.
For example, the display level determination unit 1213 may determine the reference mesh as the following three display levels. Note that the display level determination unit 1213 may calculate the reference mesh display level and register it in the storage unit 130 in advance.
-Display level A The highest priority of sightseeing spots included in the mesh is 3
-Display level B The highest priority of sightseeing spots included in the mesh is 2
-Display level C The highest priority of tourist spots included in the mesh is 1.

Next, when the size of the display mesh determined by the size determination unit 1212 is larger than the reference mesh, the display level determination unit 1213 displays the display mesh based on the display level of the reference mesh included in the display mesh. Determine the level. For example, the display level determination unit 1213 can set the display level of the reference mesh having the highest display level among the reference meshes included in the display mesh as the display level of the display mesh.
On the other hand, if the size of the display mesh determined by the size determination unit 1212 is equal to or smaller than the reference mesh, the display level determination unit 1213 determines the display level of the reference mesh corresponding to the display mesh. To do.

Based on the determined display level, the display control unit 1214 can control the icons displayed on the meshes to correspond to the sightseeing spots having a predetermined priority. In the present embodiment, as an example, the description will be given assuming that the display level and the priority of the tourist spot where the icon display is permitted are as follows.
-Display level A Only icons for sightseeing spots with priority 3 or higher are displayed.
-Display level B Only icons for sightseeing spots with priority 2 or higher are displayed.
-Display level C Displays icons of tourist spots with a priority of 1 or higher.

  Further, the display control unit 1214 generates map information by superimposing the selected icon on the map image included in the display range, and transmits the map information to the terminal device 200.

  FIG. 4 is a diagram schematically illustrating a state in which the display control unit 1214 controls the displayed icon with respect to a map in which the display level of the mesh is displayed as a heat map. The icons I003, I007, and I008 indicated by circles indicate sightseeing spots to which priority 3 is given. Further, icons I001, I009, I010, and I011 indicated by squares indicate sightseeing spots to which priority 2 is given. Further, icons I002, I004, I005, and I006 indicated by triangles indicate sightseeing spots to which priority 1 is given.

  In the example of FIG. 4, the map displayed on the terminal device 200 is divided into four meshes M01, 02, 03, and 04. In this example, it is assumed that the mesh M03 is a display level A mesh, the meshes M01 and M04 are display level B meshes, and the mesh M02 is a display level C mesh. Further, in the description of FIG. 4, an icon displayed with a solid line is an icon that is actually displayed on the map, and an icon displayed with a dotted line is an icon that is not actually displayed on the map. To do.

FIG. 4A shows a map when icons corresponding to all the sightseeing spots included in each mesh are displayed.
On the other hand, FIG. 4B shows a map when the information processing apparatus 100 according to the present embodiment controls the icon to be displayed according to the display level of the mesh. In this case, the display control unit 1214 performs control so that only icons corresponding to sightseeing spots having a priority of 3 or higher are displayed on the mesh M03 of display level A. As a result, only a round icon is displayed on the mesh M03, and no triangle or square icon is displayed. In addition, the display control unit 1214 performs control so that only icons corresponding to sightseeing spots having a priority of 2 or higher are displayed on the meshes M01 and M04 of the display level B. As a result, the round icons and the square icons are displayed on the meshes M01 and M04, but the triangular icons are not displayed. Further, the display control unit 1214 controls the mesh M02 at the display level C so that icons corresponding to tourist spots having a priority of 1 or more are displayed. As a result, any icon of a round shape, a square shape, or a triangle shape is displayed on the mesh M02.

  Next, a map display process flow of the information processing apparatus 100 will be described with reference to FIG. Each processing step included in the processing flow described below can be executed in any order or in parallel as long as there is no contradiction in the processing contents. These steps may be added. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  When the user operates the terminal device 200 to activate the map application, the user selects a point where the map is to be displayed. This selection may be performed by inputting the latitude / longitude or address of the point where the map is to be displayed, or may be selected by the user from a large scale map. When the user selects a point where a map is desired to be displayed, the terminal device 200 transmits the latitude and longitude of the point to the receiving unit 1211. The user can also specify a scale for displaying the map at the same time as selecting a point where the map is to be displayed. To specify the scale, the user may input an arbitrary scale directly from the input unit 210 of the terminal device 200, or a pinch operation may be performed on the display unit 250. The scale designated by the user is transmitted to the reception unit 1211. When the user does not specify a scale, it is desirable that a default scale is used as the scale of the map displayed on the terminal device 200. The default scale may be set in advance on the information processing apparatus 100 side, or the user may register an arbitrary value in advance. In the example of FIG. 5, the description will be made assuming that the user has designated 1/25000 as the scale.

  The reception unit 1211 determines a display range of a map to be displayed on the terminal device 200 from the received latitude / longitude and scale. At this time, it is desirable that the display range of the map is determined so that the point selected by the user is displayed at the center. The size determination unit 1212 determines the size of the display mesh that divides the map displayed on the terminal device 200 from the scale received by the reception unit 1211 (S100). The size determination unit 1212 refers to the mesh size DB 131 and determines a size of 10 km × 10 km as the size of the mesh corresponding to 1 / 25,000 which is the scale received by the reception unit 1211.

Next, when the size of the reference mesh is larger than the size of the display mesh (S101: NO), the display level determination unit 1213 determines the display level of each display mesh according to the display level of the reference mesh including the display mesh. (S112).
On the other hand, when the size of the reference mesh is equal to or smaller than the size of the display mesh (S101: YES), the display level determination unit 1213 displays the display level of the reference mesh having the highest display level among the reference meshes included in the display mesh. Accordingly, the display level of each display mesh is determined (S102).

  The display level is preferably determined in real time by the display level determination unit 1213 based on the priority of the tourist spots included in the mesh, but may be determined and recorded in advance. The display level determination unit 1213 repeatedly executes the process of S102 or S112 until the display level is determined for all meshes included in the display range.

  When the display level determining unit 1213 determines the display level for all the meshes included in the display range (S103: YES), the display control unit 1214 displays on each mesh based on the display level. Is selected (S104). Specifically, the display control unit 1214 performs control so that the icon of a sightseeing spot having a priority level of 3 or higher is displayed on a mesh whose display level is A, and the priority level of 2 or higher is displayed on a mesh whose display level is B. Control is performed so that the icon of the tourist spot is displayed, and the icon of the tourist spot having a priority of 1 or higher is displayed on the mesh whose display level is C. Further, the display control unit 1214 generates map information by superimposing the selected icon on the map image included in the display range, and transmits the map information to the terminal device 200.

  Each time the user changes the scale or map display point, the information processing apparatus 100 repeatedly executes the processes of S101 to S104.

  As described above, according to the information processing apparatus 100 according to the present embodiment, it is possible to control the display of the map so that the importance of the displayed icon can be consistent in units of meshes.

[Second Embodiment]
In addition to the functions described in the first embodiment, the information processing apparatus 100 according to the present embodiment has a function of adjusting the display level so that the display level of the mesh changes stepwise.

  In addition to the functions described in the first embodiment, the display level determination unit 1213 adjusts the display level of the divided mesh when there is a mesh whose display level is more than a predetermined level away from the display level of other meshes. To do. For example, when the display levels of two adjacent meshes that are included in the map displayed on the terminal device 200 are separated by two or more levels, the display level determination unit 1213 displays the two adjacent meshes. A process of raising the display level of the mesh having the lower display level may be performed. A specific example of processing of the display level determination unit 1213 in this case will be described with reference to FIG.

  FIG. 6A is a diagram schematically illustrating a state in which the display level determined by the display level determination unit 1213 is displayed as a heat map. A mesh M13 represents a display level A mesh. Mesh M11 represents a display level B mesh, and meshes M12 and M13 represent a display level C mesh. In addition, it is assumed that the numbers written inside each mesh indicate the score of each mesh.

  The display level determination unit 1213 displays the display level of the mesh M13 and the meshes adjacent to the mesh M13 (that is, the meshes M11 and M14, and the meshes M11 and M14 adjacent to the mesh M13 below are also referred to as “adjacent meshes”). If the display level of the mesh M11 or mesh M14 is lower than a predetermined level than the display level of the mesh M13, the display level of the mesh M11 or mesh M14 can be raised. For example, in the example of FIG. 6A, the mesh M14, which is an adjacent mesh of the mesh M13, is a mesh whose display level is two or more steps away from the mesh M13. For such an adjacent mesh, the display level determination unit 1213 may perform a process of changing the display level.

  Specifically, it is assumed that the display level determination unit 1213 raises the level with respect to the display level of the mesh M14. As a result, as shown in FIG. 6B, the display level of the mesh M14 is changed from C to B.

  Further, the display level determination unit 1213 may change the display level of the mesh adjacent to the mesh having the highest display level among the meshes included in the display range of the map. For example, in the example of FIG. 6A, the mesh M13 is the mesh with the highest display level. Therefore, the display level determination unit 1213 may increase the level of the mesh M11 and the mesh M14 adjacent to the mesh M13.

  A flow of map display processing of the information processing apparatus 100 according to the present embodiment configured as described above will be described with reference to FIG. In addition, since the process of S101-S103, S104, and S105 is the same as that of 1st Embodiment, it abbreviate | omits description.

In S103, in this embodiment, the display level determination unit 1213 completes the determination of the display levels of all the meshes within the display range (S103: YES), and the display level of the meshes that are separated from each other is in a predetermined stage ( For example, a search is performed for a mesh that is more than two steps away (S113). If there is a mesh in which the display levels of the meshes that are separated from each other are separated by two or more levels (S113: YES), the display level determination unit 1213 performs a process of raising the display level of the lower mesh (S114).
Other configurations and functions are the same as those in the first embodiment.

[Third Embodiment]
The display level determination unit 1213 according to the present embodiment can determine the number of icons to be displayed in the display mesh based on the priority sum of the tourist spots in the display mesh.

  Specifically, the display level determination unit 1213 refers to the priority DB 132 and adds a value corresponding to the priority of the tourist spot included in each display mesh. As an example in this embodiment, 5 points corresponding to priority 3 tourist spots, 3 points corresponding to priority 2 tourist spots, 1 value corresponding to priority 1 tourist spots, The display level determination unit 1213 will be described as determining the number of icons to be displayed on each mesh.

  For example, when a certain mesh includes three sightseeing spots with priority 3, one sightseeing spot with priority 2, and one sightseeing spot with priority 1, display level determination unit 1213 gives the score of this mesh. Can be determined as 19 points (5 points × 3 + 3 points × 1 + 1 point × 1), and the number of icons to be displayed can be determined according to the score.

  The number of icons may be N from the top in descending order of priority (where N is a natural number), M icons with priority 3, K icons with priority 2, and priority 1 The number of displays may be determined for each priority, such as L icons (M, K, and L are preferably natural numbers such that M ≧ K ≧ L). In the former case, unless the number of determined icons is larger than the number of tourist spots with priority 3 included in the display mesh, icons corresponding to tourist spots with priority 2 are not displayed. In the latter case, it is desirable that a display order is further set in the priority DB 132 for each priority of sightseeing spots. The display order indicates the priority for displaying icons in tourist spots having the same priority.

The display control unit 1214 can control the icons displayed on the respective meshes based on the determined number of icons.
Other configurations and functions are the same as those in the first embodiment.

[Other embodiments]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.

  For example, in the above-described embodiment, the icon is described as displaying a tourist spot on a map, but the present invention is not limited to this. The icons may display intersections, roads, buildings, etc. on the map. For example, when each icon corresponds to an intersection, priority 3 is given to the intersection connecting to the national road, priority 2 is given to the intersection connecting to the prefectural road, and connection is made only to other roads. Priority 1 may be given to the intersection.

  For example, in the above-described embodiment, the display level determination unit 1213 has been described as adjusting the display level of a mesh whose display level is lower than the display level of another mesh by a predetermined level or more, but the present invention is not limited to this. For example, the display level determination unit 1213 may lower the display level of the mesh with the highest display level, or the average display level of the meshes included in the map in the display range as the display level of the mesh with the highest display level. Also good.

For example, in the above-described embodiment, the display level determination unit 1213 has been described as determining the display level of the display mesh based on the display level of the reference mesh. However, the present invention is not limited to this.
For example, the display level determination unit 1213 can determine the display level of the mesh by referring to the priority DB 132 and adding a value corresponding to the priority of the tourist spot included in each mesh. As an example, the display level determination unit has 5 points corresponding to priority 3 tourist spots, 3 points corresponding to priority 2 tourist spots, and 1 value corresponding to priority 1 tourist spots. 1213 will be described as determining the display level of each mesh.
In this case, the display level determination unit 1213 also refers to the sum of values corresponding to the priority of tourist spots in each mesh (hereinafter, the sum of values corresponding to the priority of tourist spots included in the mesh is also referred to as “score”. ), The mesh may be determined at the following three display levels.
