BACKGROUND OF THE INVENTION
The present invention relates to a navigation device that displays a map image around a vehicle position or around an arbitrarily designated position.
[0002]
[Prior art]
In general, an in-vehicle navigation device has a map display function for displaying a map image around a vehicle position or an arbitrary position designated by a user on a screen, or up to a destination or waypoint designated by a user. A route search function for searching the route, a route guidance function for guiding the traveling of the vehicle along the route obtained by the route search, and the like. In addition, when displaying a map image on the screen, most navigation devices display a specific image indicating a specific facility (for example, a convenience store, a bank, a public office, etc.) designated by the user over the location. It has a facility guidance function.
[0003]
Usually, each of these functions is realized by performing predetermined processing based on map information provided via a disk type medium such as a CD (compact disk) or a DVD (digital versatile disk), a communication medium, or the like.
Some recent vehicles are equipped with a hands-free device that can make a mobile phone call while driving, or a mobile phone that is called while driving. In this device, predetermined switches are provided in the vicinity of the handle, and by operating these switches, a call can be made to an incoming mobile phone or a telephone number registered in a mobile phone memory. Can be applied.
[0004]
For example, in the above-described hands-free device, the registered contents of the memory of the mobile phone are displayed in a list using a display device provided in a navigation device or the like, and a call is made to one phone number selected by the user from among them. You can hang it.
[0005]
[Problems to be solved by the invention]
By the way, by using the facility guidance function of the navigation device described above, a specific image indicating the location of a specific facility can be displayed superimposed on a map image. Whether or not a specific facility is included in the displayed map image can be easily known only by looking at the displayed map image. However, in the same way, even when trying to know the location of a specific company or the like related to a friend's house or the user himself / herself, the conventional navigation device does not have a function for displaying these locations on a map image. There is a problem that such a display is impossible or a complicated operation is required to perform an equivalent display.
[0006]
For example, in a conventional navigation device, an arbitrary point can be registered. When this registered point is included in the display range of the map image, a predetermined image (for example, a flag mark) is displayed at the registered point. Some have a function of displaying. For this reason, by registering all of the friend's homes for which you want to display the location, it becomes possible to show these locations on the map image while traveling or scrolling. Since it is necessary to register, the operation is complicated and there is a risk of erroneous operation.
[0007]
In addition, as described above, by using a hands-free device, it is possible to send a list of mobile phone registration contents to a navigation device or the like, but since this information is used to make a call, eventually, If you want to display the location of your friend's home registered on the mobile phone on the map, display the registered content on the display of the mobile phone and display the friend's phone number etc. one by one on the navigation device operation screen You need to enter it yourself.
[0008]
The present invention was created in view of the above points, and an object of the present invention is to provide a navigation device capable of displaying a location corresponding to specific registration information on a map without performing complicated operations. There is to do.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, the navigation device of the present invention is connected by a connection means to which a portable device having a memory in which specific data capable of specifying a display position on a map is stored is connected to the connection means.

The specific data stored in the memory of the mobile device is read, the display position on the map corresponding to this specific data is specified, and the specific image to be displayed at this display position is drawn, so it is stored in the mobile device It is not necessary for the user himself / herself to input specific registration information that is complicated, and the location corresponding to the registration information can be displayed on the map. In addition, since the user himself does not perform an input operation, it is possible to prevent an input error from occurring.
[0010]
In addition, the above-described portable device is a cellular phone, and it is preferable that the data reading unit reads specific data stored in the memory using a registration function included in the address book of the cellular phone. In general, mobile phones are registered with phone numbers, etc., of friends who are likely to get in touch with you or who you have a recent relationship with, so there is a need to display the location corresponding to these registration information on a map. It is considered relatively high. Therefore, it can be said that displaying these locations on a map has a great effect of reducing the troublesome work required to display the locations corresponding to the contact information desired by the user.
[0011]
Further, the specific data described above is at least one of a telephone number and an address, and it is desirable that the display position specifying means specifies the longitude and latitude on the map as the display position based on the specific data. Many in-vehicle navigation devices have a function of searching for a corresponding position (longitude, latitude) based on a telephone number, an address, or the like. By using this function, a display corresponding to specific data is displayed. The position can be easily specified.
[0012]
The above-mentioned memory stores associated data that can be associated with names and names corresponding to the specific data, the data reading means reads the accompanying data together with the specific data, and the drawing means is used as the specific image. It is desirable to draw the contents of the accompanying data. 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 accompanying data including these nicknames and abbreviations along with numbers and addresses, and using these nicknames for display, the user can easily know the person or facility that is the subject of the location display. .
[0013]
In addition, a registration image corresponding to the specific data is stored in the above-described memory, the data reading unit reads the data of the registration image together with the specific data, and the drawing unit draws the registration image as the specific image. It is desirable. In a portable device such as a cellular phone capable of registering an image, image registration is often performed in which a telephone number or a name or name corresponding to the telephone number can be easily conceived. Therefore, by reading the image registered in the portable device and displaying it on the map, the user can easily know the person or facility that is the target of the location display.
[0014]
Further, the specific data stored in the memory described above is classified into a plurality of groups, and a selection screen drawing means for drawing a selection screen for selecting at least one of the plurality of groups, and a plurality of pieces of data included in the selection screen And a data reading means for selecting specific data belonging to the selected group when the operation means is operated and a group included in the selection screen is selected. It is desirable to read. In recent portable devices such as mobile phones, it is often possible to register a telephone number for each group created by the user himself / herself in accordance with the degree of importance and usage. Therefore, by selecting the group from these groups and narrowing the display target, only the location corresponding to the telephone number or the like that the user wants to display can be selectively displayed on the map. It becomes possible.
[0015]
The apparatus further includes a selection screen drawing means for drawing a selection screen for selecting at least one of the specific data stored in the memory and an operation means for instructing selection of the specific data using the selection screen. The data reading means desirably reads the selected specific data when the operating means is operated and the specific data is selected using the selection screen. By selecting a part from a plurality of specific data registered in the portable device, it is possible to selectively perform only the display of the really necessary location.
