[0002]

2. Description of the Related Art Generally, a vehicle-mounted navigation device has a map display function of displaying on the screen a map image of the vicinity of a vehicle position or an arbitrary position specified by a user, and a purpose specified by the user. It has a route search function for searching a route to the ground or a waypoint, a route guidance function for guiding the traveling of the vehicle along the route obtained by the route search, and the like. Also, most navigation devices
When displaying a map image on the screen, it has a facility guidance function that displays a specific image indicating a specific facility specified by the user (eg, convenience store, bank, government office, etc.) at its location. There is.

Normally, these respective functions are performed by a CD (compact disc), a DVD (digital versatile disc).
It is realized by performing a predetermined process based on map information provided via a disk-type medium such as the above, a communication medium, or the like. In addition, some recent vehicles are equipped with a hands-free device that allows a mobile phone to be called while driving and a mobile phone to be called while driving. This device is equipped with certain switches near the handle. By operating these switches, you can answer the incoming call or call the phone number registered in the memory of the call. You can make a call.

For example, in the above handsfree device,
A display device provided in a navigation device or the like can be used to display a list of registered contents in the memory of the mobile phone, and to call one phone number selected by the user from the list.

[0005]

By using the facility guidance function of the navigation device described above, it is possible to display a specific image showing the location of a specific facility on a map image, so that it is possible to avoid Whether or not the specific facility is included in the map image displayed around the host vehicle position or during the scroll operation can be easily known only by looking at the displayed map image. However, even if the user tries to know the location of a friend's house or a particular company related to the user himself in the same manner, the conventional navigation device does not have a function of displaying these locations on a map image. There is a problem in that such a display is impossible, or a complicated operation is required to perform an equivalent display.

For example, an arbitrary point can be registered in the conventional navigation device, and when the registered point is included in the display range of the map image, a predetermined image (for example, Some have the function of displaying a flag mark). Therefore, by registering all the friend's homes whose locations you want to display, it is possible to show these locations on the map image while you are running or scrolling. Since it is necessary to register, the operation is complicated and there is a risk of making an erroneous operation.

Further, as described above, by using the hands-free device, the registration contents of the mobile phone can be sent to the navigation device or the like and displayed as a list, but since these information are used for making a phone call. , After all,
When you try to display the location of your friend's home registered on your mobile phone on the map, you can display the registered contents on the display of your mobile phone while displaying the phone numbers of your friends one by one on the operation screen of the navigation device. You need to enter it yourself.

The present invention was created in view of the above points, and an object thereof is to provide a navigation capable of displaying a location corresponding to specific registration information on a map without performing a complicated operation. To provide a device.

In general, mobile phones have registered the phone numbers of friends or other people with whom they have a recent contact, so it is necessary to display the locations corresponding to these registered information on a map. It is considered relatively high. Therefore, by displaying these locations on the map, it can be said that the effect of reducing the troublesome work required for displaying the locations corresponding to the contact information desired by the user is great.

The above-mentioned specific data is at least one of a telephone number and an address, and the display position specifying means preferably specifies the longitude and latitude on the map as the display position based on the specific data. Since many on-vehicle navigation devices have a function of searching for corresponding positions (longitude, latitude) based on a telephone number, an address, etc., by using this function, a display corresponding to specific data is displayed. The position can be easily specified.

Further, the above-mentioned memory stores associated data which can be associated with a name and a name corresponding to the specific data. The data reading means reads the associated data together with the specific data and the drawing means: It is desirable to draw the contents of the accompanying data as a specific image. Considering the general usage of mobile devices such as mobile phones, when registering names and names corresponding to telephone numbers, appropriate nicknames and abbreviations that can be understood only by the user themselves are often used. By reading the accompanying data including these nicknames and abbreviations as well as numbers and addresses and using these nicknames and the like when displaying, the user can easily know the person or facility whose location is to be displayed. .

The memory stores the registered image corresponding to the specific data, the data reading means reads the data of the registered image together with the specific data, and the drawing means stores the registered image as the specific image. It is desirable to draw. In a mobile device such as a mobile phone capable of registering an image, image registration is often performed so that a telephone number or a name or name corresponding to this telephone number can be easily thought of. Therefore, by reading the image registered in the mobile device and displaying the image on the map, the user can easily know the person, the facility, or the like whose location is to be displayed.

Further, the specific data stored in the above-mentioned memory is classified into a plurality of groups, and included in the selection screen is a selection screen drawing means for drawing a selection screen for selecting at least one of the plurality of groups. And a data reading means belonging to the selected group when the operation means is operated to select a group included in the selection screen. It is desirable to read specific data. In recent mobile devices such as mobile phones, it is often possible to register a phone number for each group created by the user according to the degree of importance or the purpose of use. Therefore, by selecting the group from these groups and narrowing down the display target, the user can selectively display only the location corresponding to the telephone number etc. that the user desires to display on the map. It will be possible.

Further, there are provided a selection screen drawing means for drawing a selection screen for selecting at least one of the specific data stored in the above-mentioned memory, and an operating means for instructing selection of the specific data using the selection screen. With further preparation,
It is desirable that the data reading unit reads the selected specific data when the operating unit is operated and the specific data is selected using the selection screen. By selecting a part from the plurality of specific data registered in the mobile device, it becomes possible to selectively perform only the location display that is really necessary.

(3) Operation of Navigation Device The navigation device of this embodiment has the above-mentioned configuration, and its operation will be described next. FIG. 2 is a flowchart showing an operation procedure of the navigation device that specifies the display position based on the personal information registered in the mobile phone.

The data reading section 16 determines whether or not the user operates the remote control unit 4 to instruct to read the personal information stored in the memory of the mobile phone 7 (step 100). If the predetermined operation for instructing the reading of the personal information is not performed, a negative determination is made and this determination process is repeated. When a predetermined operation for instructing the reading of personal information is performed, an affirmative determination is made in the determination at step 100, and then the data reading unit 1
6 determines whether or not the mobile phone is connected via the cable 7a (step 101). For example, the presence or absence of the connection of the mobile phone 7 can be examined by examining the presence or absence of a specific signal output from a specific terminal for cable connection provided in the mobile phone 7. If the specific signal cannot be detected, a negative determination is made in step 101. In this case, the operation screen generator 32
Creates and displays a message screen prompting connection of the mobile phone 7 (step 102). Then step 101
Returning to, the determination as to whether or not the mobile phone is connected is repeated.

If a specific signal is detected, an affirmative decision is made in step 101, and then the data reading section 16 reads the personal information stored in the memory of the mobile phone 7. (Step 103). When the reading of the personal information is completed, the data reading unit 16 determines whether a group is set for the read personal information (step 104).

If no group is set, a negative determination is made, and then the data reading section 16 displays a list of names included in the personal information (step 10
5) Then, a process of selecting any one from the name list is performed according to the selection operation of the user (step 106). Through this selection process, one or more pieces of personal information that the user desires to select are selected from all the read personal information. The display of the name list described above is performed by creating a selection window including the name list by the operation screen generating unit 32 and displaying the selection window on the display screen.

FIG. 3 is a diagram showing a specific example of the name list display of the read personal information. As shown in FIG. 3, a selection window W1 including a list of names is displayed on a part of the screen. On the other hand, if a group is set, an affirmative decision is made in the determination at step 104, and then the data reading unit 16 displays a list of groups extracted from the read personal information (step 107). ),
A process of selecting any one from the group list according to the user's selection operation is performed (step 108). By this selection processing, personal information belonging to one or a plurality of groups that the user desires to select is selected from all the read personal information. The display of the group list described above is performed by creating a selection window including the group list by the operation screen generation unit 32 and displaying it on the display screen.

FIG. 4 is a diagram showing a concrete example of a group list display of the read personal information. As shown in FIG. 4, a selection window W2 including a group list is displayed on a part of the screen. Next, the display position specifying unit 17 extracts the telephone number included in the personal information thus selected,
Based on this telephone number, the location (longitude, latitude) of the individual or company corresponding to this personal information is specified as the display position (step 109). Then, the process returns to step 100 and the determination of the presence / absence of the instruction to read the personal information is repeated.

FIG. 5 is a flow chart showing the operation procedure of the navigation device for displaying the map around the position of the own vehicle while traveling, and shows the operation procedure for displaying the personal information whose display position is specified. There is. When the vehicle position is detected by the vehicle position calculation unit 22 based on the output of the vehicle position detection unit 5 (step 200), the map drawing unit 1
4 performs drawing processing corresponding to the vehicle position periphery based on the map data read from the DVD 2 and stored in the map buffer 10 corresponding to the detected vehicle position (step 201). This drawn map image data is VR
Written to AM20.

Next, the specific image drawing section 18 determines whether or not the display position specified corresponding to the personal information selected by the user is included in this drawing position (step 202). When the display range of the personal information is included in the drawing range, an affirmative determination is made, and then the specific image drawing unit 18
For each of the personal information included in the drawing range,
A text image indicating the name included in the personal information, or if there is a registered image, both the text image and the registered image are drawn at the display position corresponding to this personal information as a specific image corresponding to each personal information. (Step 20
3). This drawing process is performed by overwriting the map image already drawn in the corresponding area of the VRAM 20 with the specific image. After that, the map image stored in the VRAM 20 is read by the read controller 21 and displayed on the display device 6 via the image synthesizer 36 (step 204).

If the drawing range does not include any personal information display position, a negative judgment is made in step 202. In this case, the map image in which the specific image is not overwritten is read from the VRAM 20 and displayed on the display device 6 (step 204).

FIG. 6 and FIG. 7 are diagrams showing specific examples of the map image display including the specific image corresponding to the personal information. The display example shown in FIG. 6 corresponds to the case where the display position of the specific image is near the vehicle position mark G and only the text image included in the personal information is included as the specific image. In the example shown in FIG. 6, text images indicating the names “Taro” and “Tsuyoshi” are displayed as the specific images.

Further, in the display example shown in FIG. 7, when the display position of the specific image is near the company position mark G, both the text image and the registered image included in the personal information are included as the specific image. It corresponds to the case. For example, when the individual upper body image corresponding to the personal information is used as the registered image, as shown in FIG. 7, the specific image including the upper body image and the text image of the name is displayed.

Next, the operation of selecting personal information in response to the selection operation by the user will be described. FIG. 8 is a flow chart showing the selection operation procedure when the personal information for which the group setting has not been made is read, and shows the detailed operation procedure of the selection processing of step 106 shown in FIG.

First, the data reading section 16 determines whether or not the user has instructed full selection for the displayed name list (step 300). If the selection instruction is given to all the registered personal information, an affirmative judgment is made, and then the data reading unit 16 selects all the personal information (step 301).

If the user does not specify full selection, a negative determination is made in step 300, and then the data reading section 16 determines whether the user has made a detailed selection instruction (step 302). ), It is determined whether the "determination" key or the like of the remote control unit 4 has been pressed to determine the selection state (step 303). When a detailed selection instruction indicating one or a plurality of names is given from the name list, an affirmative determination is made in the determination of step 302, and then the data reading unit 16 is pointed to by the detailed selection instruction. The name is specified (step 304). After that, when the “Enter” key of the remote control unit 4 is pressed, a negative determination is made in the determination of step 302 and an affirmative determination is made in the determination of step 303, and then personal information corresponding to the specified name is selected.

Personal information is selected (step 401).

If the user does not instruct full selection, a negative determination is made in step 400, and then the data reading section 16 determines whether or not the user has instructed group selection (step 402). ), It is determined whether or not the "determination" key or the like of the remote control unit 4 has been pressed to determine the selection state (step 403). When one or more groups are selected from the list of groups, an affirmative judgment is made in the determination in step 402, and then the data reading unit 16 determines that each individual included in the selected group is instructed. It is determined whether further detailed selection is instructed for the information (step 40).
4). If detailed selection is not instructed, a negative determination is made and the group instructed to be selected is specified (step 4).
05). On the other hand, when detailed selection is instructed, an affirmative determination is made in the determination in step 404, and the name pointed to by the detailed selection instruction is specified from among the names of the individual information belonging to the group instructed to be selected. (Step 406).

FIG. 10 is a diagram showing a display example of a selection window for further detailed selection of personal information included in the group instructed to be selected. For example, as shown in FIG. 10, when the selection instruction of the group “friend” is made, the display area of the group “friend” is highlighted and the name list of each personal information belonging to the group “friend” is displayed. ("Wakana", "Taro", ...) is displayed.
The user can select one or more names from the name list.

When the "determination" key of the remote control unit 4 is pressed after the identification of the group or the identification of the name within the group is completed in this way, a negative determination is made in the determination of step 402 and a determination of step 403 is made. After each affirmative judgment is made in step 1, personal information corresponding to the specified group or name is selected (step 40).
