Next, the operation will be described. First of all navigation keys
The basic operation when 51 is operated will be described. The processor 10 calculates and detects the current position of the vehicle from the information of the direction sensor 7, the speed sensor 8, the CPS device 9, and the like.
In response to this information, the processor 6 reads the map including the current location from the CD-ROM 1 and stores it in the memory 5. CD-ROM1
A plurality of reduced scale maps are recorded in the memory, and the reduced scale maps including the current location are stored in the memory 5. Processor 6
Controls the controller 15 to write data of a predetermined scale of the map stored in the memory 5 into the memory 16 or 17. One of the memories 16 and 17 is on the front side (the side where the data is transferred to the memory 20) and the other is on the back side (the side where the data is not transferred to the memory 20 and new data is written by the controller 15). There is. The front side and the back side are switched alternately, and writing by the controller 15 is always performed on the back side which does not send data to the memory 20.

The processor 6 further controls the controller 15 to draw the own vehicle mark on the front side of the memories 16 and 17 in response to the current position signal from the processor 10.

The map drawn in the memories 16 and 17 by the controller 15 has data within a predetermined range centered on the own vehicle mark,
The parallel / serial conversion circuit 18 converts the parallel data into serial data, and the color signal thereof is further converted by the color palette register 19 into a high gradation color signal and transferred to the memory 20. Which part of the map drawn in the memories 16 and 17 is transferred is specified by the processor 6 via the offset register 22 and the address counter 23.

The processor 6 can also draw a picture of, for example, an intersection recorded on the CD-ROM 1 as an image directly in the memory 20. The image thus written in the memory 20 is further transferred to the memory 21, and finally the image stored in the memory 21 is output and displayed on the display device 29 via the D / A conversion circuits 26, 27, 28. .

Next, the operation when the guide key 53 is operated will be described.
When the guide key 53 is operated, the processor 6 superimposes the guide menu on the map as shown in FIG. 4, and displays the guide menu at a predetermined position on the display device 29 (near the upper and lower sides in the figure).
To display. Now on CD-ROM1, not only line segment data that displays roads, railways, coastlines, etc. as map information,
Assuming that the symbol data that displays the symbols of each facility such as hotels, gas stations, car dealers, and parking lots is also recorded, these symbols are displayed in place with the meaning of the characters as necessary. It

A touch sensor is arranged on the front surface of the display device 29,
Touching the display position of each facility with a finger etc. will detect it.
Therefore, it is determined whether the hotel, parking lot, gas station, or dealer is selected, and when any facility is selected, the guide menu is deleted and
The symbol of the selected facility superimposed on the map is displayed at the location. For example, when a hotel is selected, as shown in FIG. 5, a hotel symbol is displayed corresponding to the location on the map. This symbol is the same as the symbol displayed when the guide menu is displayed. Therefore, the operator can almost intuitively select a desired facility by looking at the symbol without looking at the characters in the guide menu display. Further, at this time, the facilities that are not selected are not displayed, so that it is extremely easy to search for the symbol itself.
On the contrary, when the guide key 53 is not operated, only a normal map without these symbols is displayed, and therefore the map is not difficult to see.

Relatively simple numbers (numbers) that can be distinguished from each other and are continuously related to each of the symbols that represent the same type of facility,
Letters and symbols are attached. That is, for example, the symbols of each hotel are numbers such as 1, 2, and 3 and letters such as A, B, and C.
Additional marks, which are other symbols, correspond to the additional marks such as the numbers when the symbols are displayed in a superimposed manner on the map. Since the symbol is displayed at the location of the corresponding facility, the symbol of the facility located outside the map centered on the current location displayed on the screen of the display device 29 and its number are located within the range of the screen. Is not displayed until. 2 in the embodiment of FIG.
The numbered hotels are not displayed because they are located outside the map currently displayed. These numbers correspond to each hotel, and the same number is not assigned to different hotels at least within a predetermined area. Therefore, the user can specify the desired hotel by this number. Of course, the above is the same for other symbols.

When a character or the like is attached to the symbol, it can be used as the name of the facility, for example. However, since the name makes the map difficult to see, it is not a simple character in the present invention.

As shown in FIG. 5, when the selected symbol is displayed in a superimposed manner on the map, it is represented by the selected symbol at a predetermined position of the display device 29 (near the lower right side in the embodiment). Operation switches for displaying more detailed information of the facility are displayed (in the embodiment, the characters in the list are displayed). If you touch the part of the list where the characters are displayed with your finger, it will be detected by the touch sensor, and the map will be erased from the screen of the display device 29 as shown in FIG. More detailed information about the hotels displayed above will be displayed in a list. The more detailed information is, for example, a hotel name, a telephone number, an address, a feature, and the like. Therefore, the operator specifies the desired hotel by the number in the display state shown in FIG.
Further, by switching to the display shown in FIG. 6 and looking at the information where the corresponding number is attached, more detailed information of the facility can be known. At this time, the information on the facility not displayed on the map is not displayed, so that the information on the desired facility becomes easier to see. In addition, by using those having continuous relations such as numbers, it becomes easier to find a desired facility from the list.

A flowchart for the processor 6 to execute the above operation is shown in FIG. 3, for example. First, with the map displayed on the screen, the process waits until an instruction to display the symbol is given. When the display of the symbol is instructed, the position data (coordinates) of the symbol is read and the display screen (map)
It is judged whether or not it is within the range. When the symbol is located within the range of the map being displayed, the symbol is displayed superimposed on the map. Moreover, the number of the symbol is written in a predetermined stack of the memory 5. Symbols located outside the bounds of the displayed map are not displayed and their numbers are not written to the stack. After such steps have been performed for all facilities (symbols), wait until a list display instruction is given, and when the list display instruction is input, the number of the symbol stored in the stack in advance is read, and The data corresponding to the number is displayed.

FIG. 7 shows a configuration example of position data when the symbol data of such a facility is recorded on the CD-ROM 1. That is, the number within the same type of symbol is placed as a header, and the attribute that distinguishes between symbols such as hotels, dealers, gas stations, and parking lots is placed, and then the coordinates (x, y) of the position where the symbol is displayed are displayed. It is arranged.

FIG. 8 shows a configuration example of a data block of more detailed information of each facility. That is, following the number of each symbol, data such as the name, telephone number, address, and feature of the facility are arranged.

FIG. 9 shows a configuration example of the stack. That is, the number of symbols being displayed superimposed on the map is arranged first, and then the number of the symbol is arranged. For example, in the case of the embodiment shown in FIG. 5, the number of displayed symbols is 3, and the numbers of the symbols are 1, 3 and 4, so the stack data is as shown in FIG.

The case where the present invention is applied to the vehicle navigation device has been described above as an example, but the application range of the present invention is not limited thereto.

〔effect〕

As described above, according to the present invention, the display control means, when displaying a predetermined facility by superimposing it on other map information at a position where the facility is present, by using an image signal, displays the predetermined facility by different symbols for each type of facility. When the desired facility is selected based on the symbol via the selection means by this display, the detailed information display means reads the detailed information of the selected facility from the map information of the storage medium and displays it on the display device. Therefore, it is possible to easily specify a desired facility from the facilities of the same type displayed on the display device and easily obtain detailed information.

Furthermore, in the vicinity of each of the symbols corresponding to the same type of facility, a supplementary mark such as a relatively simple number, letter, or symbol that can be distinguished from each other and is continuously related is displayed, and the selection means is used. When the desired facility is selected based on the symbol and the additional mark, the detailed information display means reads the detailed information of the selected facility from the map information of the storage medium and displays it on the display device. A desired facility can be more easily specified from the facilities of the same type and detailed information can be obtained. As a result, in a normal state, it is not necessary to display the name of the facility on the map, and it is possible to prevent the map from being difficult to see. As a result, the position of each facility and the more detailed information of the facility can be independently confirmed, and operability can be improved.
