For example, the storage unit 130 can be realized by a storage device such as a hard disk. Is possible. The storage unit 130 stores an area information table 130A, a background information table 130B, a character information table 130C, and a background image table 130D.

  FIG. 4 is a diagram showing the area information table 130A. For example, in the area information table 130A, as shown in FIG. 4, an area ID and coordinate information corresponding to the area are stored in association with each other.

FIG. 5 shows the background information table 130B, and FIG. 6 shows the character information table 130C.
Background information refers to information that describes the background of a related area. As shown in FIG. 5, the background information table 130B corresponds to the background information ID, the coordinate information of the area related to the background information stored in the record, and the storage location of the vector data describing the background of the related area. Is stored. Although not shown in FIG. 5, the altitude in the related area may be stored in each record.

  Character information refers to information representing note characters written on a map. As shown in FIG. 6, the character information table 130 </ b> C stores character information IDs, coordinate information of note character description locations, and storage locations of vector data related to note characters in association with each other. Further, the character information table 130C stores the background image ID corresponding to the description location of the note character. As a result, even when a plurality of background images having different altitudes exist in the same area, it is possible to display the note characters on an appropriate background image.

  FIG. 7 is a diagram showing the background image table 130D. The background image is an image related to an area, and specifically refers to a raster image generated by the image processing unit 112 from vector data of background information. As shown in FIG. 7, in the background image table 130D, the corresponding background information ID, the coordinate information of the area related to the background image stored in the record, and the storage location of the raster image are stored in association with each other. . Although not shown in FIG. 7, the altitude in the related area may be stored in each record.

  Returning to FIG. 3, the continuation of the configuration of the information processing apparatus 100 will be described. The communication unit 140 is configured to connect the information processing apparatus 100 to the network 300. For example, the communication unit 140 can be realized by using a LAN card, an analog modem, an ISDN modem, and the like, and an interface for connecting them to the processing unit via a transmission line such as a system bus.

  Further, as illustrated in FIG. 3, the arithmetic processing unit 111 includes a request receiving unit 111A and a map output unit 111B as functional units.

  111 A of request | requirement receiving parts are comprised so that the map display request | requirement which designated the coordinate of the designated position from a user may be received via the communication part 140. FIG. The request reception unit 111A extracts the coordinates of the designated position from the map display request and passes them to the subsequent processing. Further, it may be determined whether or not the coordinates of the extracted designated position are an appropriate value. Specifically, it is determined whether or not the coordinates of the designated position are not nonexistent values and are included in the displayable range handled by the communication system.

  The map output unit 111B is configured to accept the processing from the request reception unit 111A, and create and output a map image from the background image and the character information. The map output unit 111B refers to the area information table 130A and determines an area corresponding to the coordinates of the designated position received by the request receiving unit 111A. Next, a background image related to the area corresponding to the coordinates of the designated position is acquired with reference to the map image table 130D. Further, the character information table 130 </ b> C is referred to, and character information whose place is described in the area corresponding to the coordinates of the designated position is acquired. When there are a plurality of corresponding character information, the map output unit 111B desirably acquires all of them. The map output unit 111B creates and outputs a map image using the acquired background image and character information. At this time, the map output unit 111B can create a map image by superimposing the note characters on the corresponding coordinates of the background image based on the coordinate information of the description location of the note characters stored in the character information table 130C. it can.

  Further, as shown in FIGS. 2B and 2C, the map output unit 111 </ b> B is configured to display a plurality of map images having different altitudes on each map image by, for example, connecting the upper and lower background images with dotted lines. It is desirable to output so as to perform alignment based on points having substantially the same latitude and longitude.

  In addition, the map output unit 111B stores a plurality of background images with different altitudes related to the area corresponding to the coordinates of the designated position in the background image table 130D, for example, when the corresponding area is in an underground mall or a building. If so, a map image is created using an image obtained by deforming each of the background images. Specifically, the rectangular area in the image is deformed so as to become a trapezoid area or a parallelogram area. At this time, when a plurality of character information with different altitudes corresponding to the deformed background image is stored in the character information table 130C, the map output unit 111B displays the corresponding character information for each deformed background image. Use to create a map image.

  For example, it is assumed that two background images with different altitudes, a background image IID001 and a background image IID002, are stored in the background image table 130D as background images related to the area corresponding to the coordinates of the designated position. At this time, the character information table 130C stores character information CID001 and character information CID002 as character information corresponding to the background image IID001, and character information CID003 and character information CID004 as character information corresponding to the background image IID002. A case will be described as an example. First, the map output unit 111B transforms the background image IID001 into a parallelogram, and acquires vector data of the note characters of the character information CID001 and the character information CID002. Furthermore, based on the coordinate information of the description location of the note character in the character information CID001 and character information CID002, each note character is superimposed on the deformed background image IID0001, and a map image is output. By performing the same processing for the background image IID002, the character information CID003, and the character information CID004, a map image can be created using the corresponding character information for each background image.

  In addition, it is desirable that the map output unit 111B controls the size of the note character according to the coordinate information of the place where the note character corresponding to the acquired character information is written. For example, as shown in FIG. 8, the depth may be expressed by controlling the front note character to be larger and the back note character to be smaller.

  Next, a processing flow of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 9 is a chart showing a map output process flow of the information processing apparatus 100. 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.

  The user operates the portable terminal 200A to transmit a map display request to the request reception unit 111A. At this time, the user designates a position where the map is to be displayed and transmits a request. The designation of the display position may be a coordinate input or an area selection. When the map display request transmitted from the user is received (S101: YES), the request reception unit 111A determines whether or not the coordinates of the designated position are appropriate (S102). Specifically, it is determined whether or not the coordinate value of the designated position is appropriate and whether or not the designated position is within a map displayable range.

  When the request receiving unit 111A determines that the coordinates of the designated position are inappropriate (S102: NO), the arithmetic processing unit 111 requests the user to input the designated position again and transmit a map display request. (S151). For this request, for example, it is desirable to display a message to that effect on the screen of the mobile terminal 200A.

  When the request receiving unit 111A determines that the coordinates of the designated position are appropriate (S102: YES), the request receiving unit 111A notifies the map output unit 111B of the received designated position. Upon receiving the notification, the map output unit 111B determines an area corresponding to the coordinates of the designated position with reference to the area information table 130A. Next, a background image related to the corresponding area is acquired with reference to the background image table 130D (S103). When a plurality of related background images are stored in the background image table 130D (S104: YES), all the background images are acquired, and the map output unit 111B converts the rectangular area of each background image into a trapezoid or It is transformed into a parallelogram (S105).

  Thereafter, the map output unit 111B refers to the character information table 130C and obtains character information in which the corresponding character is included in the corresponding area (S106). Upon obtaining the background image and the character information, the map output unit 111B creates a map image by superimposing the note character on the background image corresponding to the character information, and outputs the map image (S107). The output map image is transmitted to the mobile terminal 200A via the communication unit 140, and a map is displayed on the screen of the mobile terminal 200A.

  As described above, when the information processing apparatus 100 displays a plurality of maps having different altitudes in the same area, the user intuitively grasps the upper and lower correspondence relationship of each map by deforming the rectangular area of the background image. It can be displayed as possible.

Specifically, the information processing apparatus 100 included in the communication system searches for a recommended route from a starting point (referred to as a user's current location or a specified position) specified by the user to a destination, and the network 300 The recommended route information is provided to the mobile terminal 200 via the. The route search request transmitted from the portable terminal 200 is received by the request receiving unit 111A and passed to the subsequent processing.

  FIG. 10 is a block diagram of the information processing apparatus 100 according to the present embodiment. As shown in FIG. 10, in the present embodiment, the storage unit 130 further includes a route information table 130E, and the arithmetic processing unit 111 further includes a route search unit 111C.

  A route is a path from a starting point to a destination, which is composed of nodes and links. A node refers to a point where a plurality of routes branch, such as an intersection or an expressway interchange, and a link refers to a route such as a road divided by nodes. As shown in FIG. 11, the route information table 130E stores a link ID that is a link identifier, coordinate information that indicates a range of the link, and weight information that is easy to search for a link. For the weight information parameter, it is possible to use information such as distance, whether it is a general road or a toll road. The higher the weight, the easier the link may be recommended.

  The route search unit 111C is configured to search for a recommended route from the departure place to the destination in response to a route search request from the user. For this route search, the weight information of each link stored in the route information table 130E can be used. The route search unit 111C determines a recommended route based on the searched link. Then, information for displaying the recommended route on the map image is transmitted to the mobile terminal 200 via the communication unit so that the mobile terminal 200 can perform the drawing process of the recommended route.

  When the area having a plurality of background images having the same coordinates and different altitudes is included between the departure point and the destination, the route search unit 111C also searches for a route in the vertical direction such as a staircase or an elevator. FIG. 12 is an example of a map on which the recommended route displayed on the mobile terminal 200 at this time is described. As illustrated in FIG. 12, the route search unit 111 </ b> C displays from which position in the area 501 and from which position in the area 502 the connection point is displayed as a connection point when indicating the movement route from the area 501 to 502. . For example, the connection point may be displayed as a line segment connecting each area. Specifically, as shown in FIG. 12, the exit point from the area 501 and the entry point to the area 502 are displayed as a connection point 601, and the exit point from the area 502 and the entry point to the area 503 are displayed as a connection point 602. The

  Next, a route search processing flow of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. The map image can be created by the processing flow shown in FIG. In addition, 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.

  The user operates the mobile terminal 200A to transmit a route search request to the request reception unit 111A. At this time, the user transmits a request by designating the starting point and destination of the route to be searched. The starting point and destination may be specified by inputting coordinates or selecting an area. When the route search request transmitted from the user is received (S201: YES), the request reception unit 111A determines whether the coordinates of the departure point and the destination are appropriate (S202). Specifically, it is determined whether or not the values of the coordinates of the starting point and the destination are appropriate, and whether or not these coordinates are within a map displayable range.

  When the request receiving unit 111A determines that the coordinates of the departure point or the destination are invalid (S202: NO), the arithmetic processing unit 111 inputs the departure point and the destination position again to the user and searches for a route. A request is sent to send the request (S251).

  When the request receiving unit 111A determines that the departure point and the destination are appropriate (S202: YES), the request receiving unit 111A notifies the route search unit 111C of the received departure point and destination. Upon receiving the notification, the route search unit 111C searches the recommended route with reference to the route information table 130E (S203). Furthermore, the route search unit 111C refers to the background image table 130D, and if the recommended route provided to the user includes an area having a plurality of background images with different altitudes (S204: YES), the route search unit 111C connects to the upper and lower areas. The coordinates to be a point are acquired (S205).

  Thereafter, the route search unit 111C uses the communication unit 140 as information for displaying the acquired connection point coordinates and recommended route information on the map image created by the map output unit 111B by the flow shown in FIG. To the portable terminal 200A (S206).
