1 is a block diagram of a circuit according to the present invention. 1
Is a storage device for storing the digitized map, and is constituted by a CD-ROM or the like. Reference numeral 2 is a display device such as an LCD or a CRT, which displays a map, telephone number information and the like. Reference numeral 3 denotes a storage device for storing coordinates indicating the position on the digitized map, a telephone number, and an identification name for identifying these data, which is composed of an S-RAM or the like. Reference numeral 5 denotes a telephone, which is controlled by a controller 7 described later and has a so-called speed dial function of dialing a telephone number designated by the controller 7. 6 is a device for displaying necessary information and symbols other than a map on the display device 2, for example,
This is a so-called image processing device that synthesizes an arbitrary image such as a mark indicating the main body of the telephone on the map or overwrites information on the map. At the center of each of the above devices, a control device 7 including a CPU that performs overall control and calculation is connected. Then, the control device 7
On the other hand, a key input device 4 such as a key pad for inputting various data or a touch panel is connected.

The digitized map contains absolute coordinates on the map. This requires at least one point in the displayed map, and by using the absolute coordinate values of the two points on the map, the calculation by the control device 7 can be used to calculate any point on the map. The coordinate value of a point can be calculated. Further, in the case where the digitized map has a hierarchical structure, arbitrary position information on the displayed map can be obtained from the scale of the displayed map and the coordinate value of one point on the map. Generally, position information is displayed in latitude and longitude.

The present invention roughly includes two functions. One is a telephone number information input function that sets one point on the map and inputs the telephone number and identification name to it. The other is to specify the data by the key input device on the map and make a call. It is a calling function.

First, referring to the flowchart of FIG. 2, the telephone number information input function will be described. First, the key for starting the input is input (step 101). in this case,
The control device 7 monitors whether or not a key for starting the input of telephone number information is input from the key input device 4, and if it is confirmed that the key has been input, an arbitrary point on the map is input to the key input device 4 To select the telephone number information input position (step 10).
3). This is a step that exists when the input device is a mouse or a cursor key of a keyboard, and does not exist when the input device is a touch panel. Subsequently, the control device 7 calculates the coordinates of the determined position of the key from the absolute coordinate position on the map and the scale (step 104), and accepts the telephone number input from the key input device 4 (step 105). When the input is completed, a key which signifies the end of the input of the telephone number is input in advance (step 106).

Subsequently, the control device 7 receives the input of the identification name from the key input device 4 (step 10).
7) When the input is completed, enter a key that signifies the end of the input of the identification name determined in advance (step 10).
8). The control device 7 is the storage device 3 having the S-RAM configuration.
The location on the map, the telephone number, and the identification name entered here are stored (step 109), and the telephone number information stored in the storage device 3 is stored in the map currently displayed on the display device 2. If there is, the control device 7 sends the telephone number information from the storage device 3 to the image processing device 6 (step 1).
10). The image processing device 6 performs a process of determining the display coordinate position and the display symbol based on this information, and the display device 2 displays
A symbol indicating that the telephone number is stored is displayed on the map by overwriting or the like (step 111).

The above operation is premised here to be input by the user of the apparatus, but should be input by a third party before input by the user, for example, at the equipment manufacturer or dealer. Can also be considered.

Next, the calling function will be described. First, if there are multiple maps, you must select the map to display. The map is selected using the key input device 4. By inputting the key of the key input device 4, the control device 7 determines which of the maps stored in the storage device 1 is to be displayed. When determined, the control device 7 sends the map information in the storage device 1 to the image processing device 6 and causes the display device 2 to display the corresponding map. In addition, the control device 7
Searches the storage device 3 for telephone number information that can be displayed on the displayed map, and if it exists, sends the telephone number information to the image processing device 6. The image processing device 6 overwrites and displays on the display device 2 a symbol indicating that the telephone number information is stored on the displayed map.

After this state, the operation will be described with reference to the flow chart of FIG. The key for telephone call is input, and the control device 7 checks it (step 201). Next, the control device 7 calculates the coordinates indicated by the key input of the key input device 4 based on the scale and absolute position coordinates of the displayed map (step 202). Continuing on, the controller 7
The telephone number information stored in the storage device 3 is searched for one that matches the coordinates of the key that is currently input (step 203), and it is determined whether there is a matching one (step 20).
4) If there is a match, the telephone number information is sent from the storage device 3 to the control device 7 (step 205). The control device 7 controls the telephone 5 to dial the number of the telephone number information to make a call (step 206).

In steps 203 and 204, the control device 7 searches the telephone number information stored in the storage device 3 for the one that matches the coordinates of the key currently input (step 203), and matches it. It is judged whether or not there is something (step 204), and if there is no suitable one,
Information is sent to the image processing apparatus 6 so as to display information indicating that there is no matching telephone number information (step 207). The image processing device 6 processes this information (step 208), and the display device 2 displays that there is no matching telephone number information (step 209).

In the above embodiment, the storage device 2 is the CD-R.
Although the OM and the storage device 3 are configured by S-RAM and both are installed inside the device, as another embodiment (not shown), the digitized map database and most of the telephone number information are completely stored. It is also possible to put it outside. On the host side, this is a storage device for storing a map database and a storage device for storing a telephone number (the two storage devices may be the same, but it is expected to be quite large). ), A telephone, a modem for communicating with the outside using a telephone line, and a control device for controlling these, and as a terminal side, a storage device having a smaller capacity than the host side, a telephone, a modem, a control device. , And by providing a display device.

Further, although the above description is centered on making a telephone call from the map information, conversely, it is possible to determine the address on the map from the telephone number information. It goes without saying that it will be clear to any trader.

As described above, according to the present invention, the car navigation system and the car phone, which have been conventionally separate, are mutually utilized, and a simple key can be used from the state in which the map is displayed on the display device. You can make a phone call by inputting, or you can search for an address on the map by phone number. Furthermore, if an external storage device is used as described in another embodiment, the terminal in the automobile can be downsized, and if the map side, the telephone company, etc. does the host side, the current residential map and telephone directory can be saved. Beyond that, the small terminal has the great effect of being as convenient as having an enormous map and a telephone directory.
