Based on the map data 10, the in-block determination means 28 determines whether or not the acquired current position is in the block indicated by the map data 10. When it is determined that the current position is in the block, the deformed map display means 30 converts the latitude and longitude of the current position into a position on the deformed map, and displays the current position in the block.

  In addition to the above, the mobile phone device 2 is provided with a call circuit, etc., which is omitted in FIG.

The server program 72 performs its function in cooperation with the OS 70. The OS 70 and the server program 72 are installed on the hard disk 66 via the CD-ROM drive 64 from what is recorded on the CD-ROM 76.

  FIG. 4 shows image data of a deformed map. FIG. 4 shows only a part of the image data. In this embodiment, the display of lines L1, L2, L3 and block B1 is provided as image data. Here, the lines L1, L2, and L3 indicate roads for movement and the like, and indicate portions where one-dimensional movement is possible.

FIG. 7 is a diagram shown for ease of understanding, and it is not necessary to record such accurate map data in the server device 4.

1.3 Contents of Processing FIG. 8 shows a flowchart of the terminal program 54 and the server program 72. First, the CPU 40 of the mobile phone device 2 (hereinafter sometimes abbreviated as the mobile phone device 2) acquires the current position (latitude and longitude) from the GPS receiving circuit 50 (step S1). The cellular phone device 2 transmits the acquired current position to the server device 4 via the communication circuit 48 (step S2).

  The CPU 60 of the server device 4 (hereinafter sometimes abbreviated as “server device 4”) receives the current position via the communication circuit 68 (step S51). The server device 4 determines map data to be transmitted based on the received current position (step S52). For example, map data of a rectangular area within a predetermined range centering on the received current position is selected.

  Subsequently, the server device 4 transmits the determined map data (step S53). For example, map data as shown in FIGS. 4 to 6 is transmitted.

  The cellular phone device 2 receives this map data (step S3). Subsequently, the mobile phone device 2 has the current position (latitude and longitude) acquired in step S1 in any block based on the accurate block latitude and longitude data 20 indicated in the received map data. Is determined (step S4). This determination is performed as follows, for example.

  Assume that a block B1 as shown in FIG. 10A is included in the map data. FIG. 10A is created based on accurate latitude / longitude data 20. The current position is shown as point C. A straight line Qa is drawn from the current position C in parallel to the line P1-P3 toward the line P3-P4, and the intersection is defined as P34. At this time, it is determined whether or not the point P34 is on the line P3-P4.

  Similarly, a straight line Qb is drawn from the current position C in parallel to the line P3-P4 toward the line P1-P3, and the intersecting point is defined as P31. At this time, it is determined whether or not P31 is on the line P1-P3.

  Similarly, the points P21 and P24 are obtained, and it is determined whether they are on the line P1-P2 or the line P2-P4, respectively.

  If all the points P34, P31, P21, and P24 are on a predetermined line, it is determined that the current position C is in the block B1.

  For example, when the block B1 and the current position C are in the relationship as shown in FIG. 10B, the point P31 is not on the line P1-P3 and the point P24 is not on the line P2-P4. It is determined that

  The above process is performed for all blocks included in the map data. If all the blocks are set not to overlap, the remaining blocks may be omitted when it is determined that they are in a certain block.

  If it is determined that the current position is in any block, the mobile phone device 2 calculates the current position in the corresponding block on the deformed map (step S5). For this processing, block position data 18 and accurate block latitude / longitude data 20 on the deformed map of FIG. 6 are used for the target block.

  For example, it is assumed that the block B1 having a shape as shown in FIG. 10A according to the accurate block latitude / longitude data 20 is represented by a rectangle as shown in FIG. 11 according to the block position on the deformed map. At this time, the cellular phone device 2 calculates the current position c on the deformed map as follows.

  First, the cellular phone device 2 obtains a ratio R1 of the length of the line P3-P4 and the length of the line P3-P34 based on the accurate block latitude / longitude data 20 (that is, in FIG. 10A). Similarly, a ratio R2 of the length of the line P3-P1 and the length of the line P3-P31 is obtained.

  Subsequently, the cellular phone device 2 determines the point p34 on the line p3-p4 based on the ratio R1 based on the block position data 18 on the deformed map (that is, in FIG. 11). A line qa parallel to the line p3-p1 is drawn from this point p34. Similarly, the point p31 on the line p3-p1 is determined by the ratio R2. A line qb parallel to the line p3-p4 is drawn from this point p31. A point where the line qa and the line qb intersect is defined as a current position c. As described above, the current position c on the deformed map is calculated.

  In this embodiment, the block shape is a quadrangle having no obtuse angle. Accordingly, the current position on the deformed map can be calculated as described above.

  The cellular phone device 2 superimposes the current position c on the deformed map image data 12 and displays it on the touch panel 44 (step S6). Thereby, for example, a display as shown in FIG. 12 is performed.

  On the other hand, if the current position is not present in any block in step S4, the line closest to the current position is specified using accurate line latitude / longitude data 16 (see FIG. 5) (step S7).

  The cellular phone device 2 determines the closest line as follows. FIG. 13 schematically shows this process. For example, when the current position C is in the relationship shown in FIG. 13A with respect to the line L1, that is, when the angles C, P1, and P2 are obtuse angles, the distance between the current position C and the line L1 is set. The distance between C and P1. At this time, the current position C on the line L1 is P1.

When the current position C is in the relationship as shown in FIG. 13B with respect to the line L1, that is, when the angles P1, P2, and C are obtuse angles, the distance between the current position C and the line L1 is C. The distance from P2. At this time, the current position C on the line L1 is set to P2. When the current position C is in the relationship shown in FIG. 13C with respect to the line L1, that is, the corners P1, P2, C and the corner When P2, P1, and C are not obtuse angles, the length of the perpendicular dropped from the current position C to the line L1 is set as the distance between the current position C and the line L1. Further, a point P ′ where the perpendicular and the line L1 intersect is set as a position on the line L1 of the current position C.

  The cellular phone device 2 performs the above processing for all the lines L1, L2, and L3 included in the transmitted map data, and selects the line closest to the current position C.

  Subsequently, the cellular phone device 2 displays the current position c on the line corresponding to the selected line, overlaid on the deformed map (step S8). For example, when the current position C is represented as shown in FIGS. 13A and 13B, the current position c is displayed at the corresponding end of the corresponding line on the deformed map. In the case of FIG. 13C, the ratio between the lines P1-P2 and P1-P 'is obtained, and the current position c is determined and displayed according to this ratio in the corresponding line on the deformed map. Thereby, for example, a display as shown in FIG. 14 is performed.

By repeating the above processing, the current position of the user on the deformed map can be displayed in real time.

2. Second embodiment
2.1 Overall Configuration In the above embodiment, map data in a corresponding range is transmitted from the server device 4 each time according to the current position of the mobile phone device 2. However, in this embodiment, map data is recorded in the mobile phone device 2 in advance, and this is read and processed. In this way, there is no communication with the server device 4 and the processing speed is improved.

FIG. 15 shows a functional block diagram of an apparatus according to the second embodiment. The terminal device 2 carried by the user includes a current position acquisition unit 22 that acquires a current position from a GPS system or the like. Based on the map data 10 recorded in the recording unit 8, the in-block determination means 28 determines whether the acquired current position is in a block indicated by the map data 10. When it is determined that the current position is in the block, the deformed map display means 30 converts the latitude and longitude of the current position into a position on the deformed map, and displays the current position in the block. If it is determined that the current position is not in the block, the latitude / longitude of the current position is converted to a position on the closest line of the deformed map, and the current position is displayed on the line.

2.2 Hardware Configuration The hardware configuration is the same as that of the mobile phone device in the first embodiment. In this embodiment, the communication circuit 48 for connecting to the Internet is not necessarily required.

2.3 Content of Processing FIG. 16 shows a flowchart of the program of the mobile phone device 2. Although there is no communication with the server device 4, the basic processing is the same as that shown in FIGS. Corresponding steps are denoted by the same reference numerals.

According to this embodiment, it is possible to perform processing in the cellular phone device 2 without exchanging with the server during guidance. Note that the map data may be recorded in advance from the portable recording medium to the mobile phone device 2 or may be downloaded from the server device.

3. Other
(1) In the above embodiment, the case where the mobile phone device is used has been described, but other mobile information terminal devices may be used.

(2) In the above embodiment, the shape of the block region is defined as a quadrangle having no obtuse angle. However, as shown in FIG. 17, the block area may be defined as a quadrangle having an obtuse angle. In this case, when the position on the deformed map is calculated, as shown in the figure, the corresponding position may be calculated by being decomposed into a plurality of triangular regions.

  Alternatively, the block area may be defined as a triangle. In this way, even a complex shaped block can be represented as a set of triangles.

(3) In the above embodiment, the current position is acquired by GPS. However, the current position may be specified based on a signal from a base station such as a mobile phone. Further, in addition to these, the current position may be corrected by a gyro and used.

(4) In the above embodiment, the lines are all defined as straight lines. Thus, even if the line is only a straight line, a curve can be expressed approximately by combining the straight lines. However, the line definition may be recorded as a curve.

(5) Although the present embodiment is applied to the guidance of the current position, the route to the destination may be displayed on the deformed map in addition to this.

(6) In the above embodiment, the mobile phone device converts the current position on the deformed map. However, this conversion process may be performed by the server device. In this case, the mobile phone device transmits the current position to the server device. Receiving this, the server device reads the corresponding map data (map data reading means), and transmits the deformed map on which the current position is displayed to the mobile phone device (deformed map data transmitting means).
