Note that the display of the region image superimposed on the map information is an example of the display method, and the map information displayed on the display unit 24 may be displayed so that the region image can be grasped.

The configuration of the navigation device 2 is not limited to the configuration shown in FIG. The navigation device 2 is an example of a display control device. The display control device may be a display device that displays map information on the display unit.

The operation of the portable information terminal 1 will be further described using the flowchart shown in FIG. In FIG. 4, the control unit 10 determines whether or not an operation input for instructing map display has been made by the operation input unit 15 in step S <b> 11.

When an operation input for instructing map display is made (YES), the control unit 10 displays map information on the display unit 14 in step S12. If there is no map display operation input (NO)
The control unit 10 repeats the process of step S11.

In step S <b> 13, the control unit 10 determines whether or not an operation input for displaying a region image on the navigation device 2 is performed by the operation input unit 15. If the operation input for displaying the region image is made (YES), the control unit 10 shifts the process to step S14. If the operation input for displaying the region image is not made (NO), the control unit 10 performs the process step S18
To migrate.

Further, when the portable information terminal 1 and the navigation device 2 are connected, it may be determined that an operation input for automatically displaying a region image has been made.

In step S <b> 14, the control unit 10 acquires region data that specifies the map display region displayed on the display unit 14. That is, the control part 10 acquires the positional information which shows the points P1-P4 shown in FIG. 2 in step S14. The position information of the four corners of the map information displayed on the display unit 14 can be easily obtained.

FIG. 5 is an example of region data including position information of the points P1 to P4. FIG. 5 conceptually shows the area data. The position information of the points P1 to P4 is a combination of latitude and longitude. In addition, since the latitude and longitude shown in FIG. 5 are positive numbers, they represent north latitude and east longitude, but when they are negative numbers, they represent south latitude and west longitude, respectively. Further, data may be held as north latitude, south latitude, east longitude, and west longitude.

In step S15, the control unit 10 controls the communication unit 16 to transmit an area image display instruction signal including area data to the navigation device 2. The region image display instruction signal is data including, for example, a flag that instructs the display unit 24 of the navigation device 2 to display a region image indicating the region of the map information displayed on the display unit 14 and region data. Can be configured as a column.

In step S <b> 16, the control unit 10 determines whether or not an operation input for canceling region image display that instructs the operation input unit 15 to end the display of the region image is performed. If the operation input for canceling the region image display is not made (NO), the control unit 10 returns the process to step S14 and repeats the processes of steps S14 to S16.

If an operation input for canceling the region image display is made (YES), the control unit 10 controls the communication unit 16 to stop transmitting the region image display instruction signal to the navigation device 2 in step S17.

In step S <b> 18, the control unit 10 determines whether or not an operation input for canceling the map display that instructs the operation input unit 15 to end the display of the map information has been performed. If the operation input for canceling the map display is not made (NO), the control unit 10 returns the process to step S12 and repeats the processes after step S12.

When an operation input for canceling the map display is made (YES), the control unit 10 at step S19,
The map display is canceled and the process returns to step S11.

The operation of the navigation device 2 will be further described with reference to the flowchart shown in FIG.
The navigation device 2 is assumed to display map information around the current position of the navigation device 2 on the display unit 24.

6, the control unit 20 determines whether or not an area image display instruction signal is received from the portable information terminal 1 in step S21. When receiving the region image display instruction signal (YES), the control unit 20 shifts the process to step S22, and when not receiving the region image display instruction signal (NO), repeats the process of step S21.

The control unit 20 analyzes the region data included in the region image display instruction signal in step S22, and the map displayed on the display unit 14 in the map information displayed on the display unit 24 in step S23. The positions of points P1 to P4 indicating the map display area of information are searched.

In step S <b> 24, the control unit 20 determines whether the map display area of the display unit 14 is within the range of the map information displayed on the display unit 24. If within range (YES), control unit 2
In step S25, 0 (area display control unit 202) displays the area image 141 on the displayed map information as shown in FIG.

A region image 141 illustrated in FIG. 7 is an example of a region image displayed on the display unit 24. The four corners of the area image 141 correspond to the positions of the points P1 to P4 in FIG.

The user can instantly recognize where the map information displayed on the display unit 14 of the portable information terminal 1 is in the map information displayed on the display unit 24 by the region image 141. The user can easily grasp the correspondence between the map information displayed on the display unit 14 and the map information displayed on the display unit 24.

Returning to FIG. 6, if the map display area of the display unit 14 is not within the range of the map information displayed on the display unit 24 (NO) in step S <b> 24, the control unit 20 (region display control unit 202) In step S26, for example, a sentence indicating that the area image 141 cannot be displayed is displayed on the display unit 24. An image such as a mark may be used instead of the text. Auditory information may be used instead of or in addition to visual information.

In addition, when the map display area of the display unit 14 is a place different from the map information displayed on the display unit 24, the range of the map information displayed on the display unit 24 by the map display area of the display unit 14 The area image 141 cannot be displayed.

In addition, when the map information is displayed on the display unit 14 in a small area, the map display area of the display unit 14 is wider than the map information displayed on the display unit 24. The image 141 may not be displayed.

Step S26 is not necessarily provided, and can be omitted. The communication unit 26 may notify the communication unit 16 that the area image 141 cannot be displayed on the display unit 24, and may display text or the like indicating that the area image 141 cannot be displayed on the display unit 14. Similarly, auditory information may be used instead of visual information or in addition to visual information.

The control unit 20 determines whether or not the region image display instruction signal from the portable information terminal 1 has stopped in step S27 following steps S25 and S26. If the area image display instruction signal does not stop (NO), the control unit 20 returns to step S22 and steps S22 to S2.
7 is repeated.

In step S25, if a text or the like indicating that the area image 141 cannot be displayed is already displayed, the area display control unit 202 may delete the text and display the area image 31. In step S26, when the area image 141 is already displayed, the area display control unit 202 may delete the area image 141 and display a text or the like indicating that the area image 141 cannot be displayed.

When the region image display instruction signal is stopped in step S27 (YES), the control unit 20 deletes the text indicating that the region image 141 or the region image 141 cannot be displayed in step S28, and returns to step S21. Then, the processing after step S21 is repeated.

By the way, in the area image 141 shown in FIG. 7, it is difficult to recognize the relationship between the vertical direction of the portable information terminal 1 and the short sides located on the left and right in FIG. Therefore, it is preferable to add an auxiliary mark for recognizing the relationship between the vertical direction of the portable information terminal 1 and the left and right short sides to the region image 141.

FIG. 8 shows an example of auxiliary data to be added to the area data including the position information of the points P1 to P4 when adding auxiliary marks. The point P5 is position information indicating the center position of the line connecting the points P1 and P2. That is, the point P5 indicates the upper part of the map information displayed on the display unit 14.

FIG. 9 shows another example of auxiliary data. The auxiliary data shown in FIG. 9 indicates the rotation angle when the map information is rotated clockwise with north as the reference direction. Here, the rotation angle is 302 degrees, and the map information displayed on the display unit 14 indicates that the map information is rotated clockwise by 302 degrees with respect to the north. The rotation angle of the map information can be easily acquired.

The communication unit 16 transmits an area image display instruction signal including the area data and auxiliary data illustrated in FIG. 8 or 9 to the communication unit 26. The communication unit 26 receives an area image display instruction signal including area data and auxiliary data.

When the region image display instruction signal includes auxiliary data, the control unit 20 (region display control unit 20
2), in step S25, as shown in FIG.
41, for example, a mark M2 indicating the upward direction is displayed based on the auxiliary data. Mark M2
Is an example of a direction identification image.

In FIG. 10, the mark M2 is an arrow, but the type of the mark is not particularly limited. The point P5 indicates the upper side of the map information displayed on the display unit 14, but a lower position may be obtained by calculation to add a mark indicating the lower direction to the region image 141. A mark corresponding to the operation button 151 may be added below the area image 141.

When a mark is added below in the area image 141 using the rotation angle shown in FIG.
A mark may be added in the vicinity of a position intersecting the area image 141 in the direction of 302 degrees to 180 degrees from 302 degrees. Further, the region image 141 may be displayed with different colors and brightness with respect to the map information.

As another example, the area display control unit 202 may display an area image that can specify the vertical direction in the map information displayed on the display unit 24 instead of the area image 141. The region image that can specify the vertical direction is, for example, a terminal image that shows a planar external shape of the portable information terminal 1.

In order to display the terminal image on the map information, the following may be performed. As shown in FIG. 11, the communication unit 16 transmits an area image display instruction signal including identification information for identifying the model of the portable information terminal 1, area data, and auxiliary data to the communication unit 26. In FIG. 11, the auxiliary data is the rotation angle, but it may be position information indicating the point P5 shown in FIG.

The navigation device 2 that displays the terminal image is configured as shown in FIG. 12, for example.
In FIG. 12, only differences from FIG. 1 will be described. The memory | storage part 23 has memorize | stored the terminal image data 234 which shows the planar external appearance shape of the portable information terminal 1 and several other portable information terminals.

The memory | storage part 23 has memorize | stored beforehand the terminal image data 234 which shows the terminal image of various portable information terminals marketed. Alternatively, the communication unit 28 may receive terminal image data of various portable information terminals from a server (not shown) via the communication network 60, and the control unit 20 may store the terminal image data 234 in the storage unit 23.

Furthermore, when the storage unit 23 stores the terminal image data 234 in advance, and a new model portable information terminal is commercially available, the communication unit 28 receives the terminal image data of the new model portable information terminal, The control unit 20 may be configured to add new terminal image data to the terminal image data 234.

The communication network 60 may be the same communication network as the communication network 50 shown in FIG. 1 or may be a different communication network. The communication network 60 may be a telephone line or an internet line connected via a wireless LAN.

When the communication unit 26 receives an area image display instruction signal including identification information for identifying the model of the portable information terminal 1, the control unit 20 reads the corresponding terminal image data from the terminal image data 234 in the storage unit 23.

As shown in FIG. 13, the area display control unit 202 displays the terminal image 142 based on the terminal image data on the map information displayed on the display unit 24. At this time, the area display control unit 2
02 displays the terminal image 142 in the direction specified based on the auxiliary data at the position indicated by the area data in the map information.

The terminal image 142 is preferably a semi-transparent image or an image having only a contour line so that the map information of the portion overlapping the terminal image 142 can be easily seen. When the terminal image 142 overlaps the mark M1, the mark M1 is preferably displayed in a state above the terminal image 142 so that the mark M1 is not hidden.

The terminal image 142 does not need to faithfully reproduce the planar appearance shape of the portable information terminal 1,
What is necessary is just the image which shows the front image of the portable information terminal 1 roughly.

Instead of the storage unit 23 of the navigation device 2 holding the terminal image data 234, the portable information terminal 1 may transmit the terminal image data to the navigation device 2. In this case, as illustrated in FIG. 14, the communication unit 16 transmits a region image display instruction signal including a flag indicating the region image display instruction signal, region data, auxiliary data, and terminal image data. 26 may be transmitted.

The portable information terminal 1 may store its own terminal image data in the storage unit 13 in advance, or the communication unit 11 receives its own terminal image data from the server via the communication network 50, and the control unit 10 may be stored in the storage unit 13.

As described above, according to the first configuration example, the correspondence relationship between the map information displayed on the display unit 24 included in the navigation device 2 and the map information displayed on the display unit 14 included in the portable information terminal 1 is obtained. It can be easily grasped.

<Second configuration example>
FIG. 15 shows a second configuration example that is a combination of the electronic pen 3 and the navigation device 2. The electronic pen 3 and a printed matter to be described later are located at a short distance from the navigation device 2.

In the second configuration example, the display body different from the display unit 24 of the navigation device 2 is a printed matter such as a magazine, and the display unit 24 displays an area indicated by map information printed on the printed matter. is there.

6, a storage unit 33, a display unit 14, an infrared irradiation unit 37, and a reading unit 38.

The storage unit 33 stores a database 330 in which an identification number unique to map information printed on the printed matter 4 shown in FIG. 16 is associated with area data of map information. The electronic pen 3 may include a communication unit similar to the communication unit 11 of the portable information terminal 1 and may be configured to communicate with a server that stores a database similar to the database 330.

As shown in FIG. 16, the printed matter 4 has map information 41 as print information. Print 4
On the paper surface, a dot pattern composed of a plurality of fine dots is printed using ink that absorbs infrared rays. The dot pattern represents an identification number unique to each map information.
The detailed configuration of the dot pattern is described in Patent Document 2.

The dot pattern is in a state that the user cannot visually recognize or even if the dot pattern can be visually recognized, there is no problem for the user to read the map information 41 and the text information.

When the user places the tip of the electronic pen 3 on the map information 41, infrared light emitted from the infrared irradiation unit 37 is irradiated on the map information 41. It is preferable that infrared rays are emitted when the user operates an operation button (not shown).

Infrared rays are absorbed by the dot pattern and reflected by paper other than the dot pattern. Reading unit 3
8 reads a dot pattern based on the reflected infrared rays.

The control unit 30 reads the area data corresponding to the identification number indicated by the read dot pattern with reference to the database 330. The area data is position information indicating the four corner points of the map information 41, similarly to the position information of the points P1 to P4 shown in FIG.

The database 330 may store the map information identification number, the map information area data, and the auxiliary data for indicating the upward or downward direction of the map information in association with each other.

Based on the control by the control unit 30, the communication unit 36 includes region data including region data for specifying the map display region of the map information 41 of the printed matter 4 with respect to the communication unit 26, as in the first configuration example. A display instruction signal is transmitted. Similarly to the first configuration example, the navigation device 2 displays the region image on the map information displayed on the display unit 24 based on the region data.

Although the map information 41 is a quadrangle, the shape of the map information printed on the printed material 4 may be various shapes such as a polygon more than a pentagon, a circle, and a star. In the case of a shape other than a quadrangle, the area data corresponding to each shape may be used.

As described above, according to the second configuration example, it is possible to easily grasp the correspondence between the map information displayed on the display unit 24 of the navigation device 2 and the map information printed on the printed matter 4. .

In the navigation apparatus 2 shown in FIGS. 1 and 15, the control unit 20 may be configured by a microcomputer, and the operation of the navigation apparatus 2 may be executed by a computer program (display control program).

Specifically, the following steps may be executed by a computer mounted on the navigation device 2 (display control device) including the display unit 24 and the communication unit 26 (reception unit).

As a display step, the computer displays the first map information on the display unit 24. When the communication unit 26 receives the region data for specifying the region of the second map information displayed on the display body different from the display unit 24, the computer determines the second data specified by the region data as the determination step. It is determined to which position of the first map information the area of the map information 2 corresponds. Step S23 in FIG. 6 corresponds to a determination step.

As a display step, the computer displays a region image indicating the region of the second map information at the position of the first map information determined in the determination step. Step S25 in FIG.
This corresponds to the display step.
