For example, the most desirable route may be specified by calculating the time and time.

[2. Operation] The present embodiment configured as described above operates as follows. [2-1. Editing of Display Graphic Information] First, FIG. 2 is a flowchart showing a processing procedure for editing the display graphic information included in the map database in the present embodiment. To edit a landmark, the user designates a desired point on the map by moving the cursor with a joystick, for example, in the input unit 25, and presses an edit button on the remote controller in advance. It is sufficient to perform the specified editing operation.

When the editing unit 213 detects that the user has performed such an editing operation, first, the editing unit 213 first expresses the latitude and longitude (denoted as D11) of the designated point (referred to as the designated point).
(Step 11), and the user is allowed to select the type of editing (step 12). This type of selection can be performed, for example, by selecting “new”, “change” or “delete” from the menu on the display screen through the input unit 25, or by using a speech recognition technique such as “shinki” or “healthy”. Can be performed by recognizing

When the change or deletion is selected, the IDs (denoted as D12) of the landmarks located around the designated point are searched and read from the map database (step 13). Here, landmark ID
(Referred to as a landmark ID) is a code for specifying the type of landmark. For example, for each different code,
XX chain convenience store, XX bank, XX
Petroleum gas stations and the like are supported, and the display screen corresponds to the display of such company symbol marks.

From among these ID groups D12,
The ID of the landmark to be changed or deleted (called the old landmark ID) and its latitude and longitude (these IDs and latitude and longitude are collectively represented as D13) are selected (step 14). In this selection, the one closest to the designated position may be selected, or the user may make such selection or change. On the other hand, if it is selected in step 12 to add the landmark to “new”, the acquired latitude and longitude (denoted as D11) of the designated point is selected as an edit target (step 16).

When the object to be edited is selected in this manner, the editing unit 213 subsequently outputs the ID of the new landmark (D1
4) (step 17). In this processing, specifically, for example, the type of editing is “delete”
In the case of, a predetermined ID indicating deletion (called a code for deletion)
May be automatically selected by the editing unit 213.

When changing a landmark or adding a new one, a list of selectable candidates is displayed on the display screen, and a candidate is pointed by a cursor or a number is uttered and input by voice recognition. You can make it specified. The newly selected ID is called a new landmark ID. In addition, in the case of adding a new landmark, a predetermined ID representing “no landmark” or an ID having no meaning such as zero may be used as the old landmark ID.

As a result of the above-described processing, (1) the latitude and longitude of the old landmark and the ID (D13) and (2) the new landmark ID (D14) are aligned, and these are stored in the SRA with battery backup.
The editing process is completed by registering in the RAM 22 such as M (step 18).

FIG. 3 is a conceptual diagram exemplifying a structure of a landmark information table provided on the RAM 22 for storing such editing contents. That is,
In this example, a unique number such as 1, 2, 3,...
(Coordinates), item 12 (old landmark ID), item 1
3 (new landmark ID) is registered.

Here, an example is shown in which the latitude and longitude and ID of the old landmark and the new landmark ID are registered together in the RAM 22 at the end of the processing. However, information obtained up to that point during the processing is stored. The information may be sequentially registered in the RAM 22. For example, in step 14, the ID and the latitude and longitude of the landmark to be changed / deleted are written in items 11 and 12, in step 16, the longitude and latitude D11 of the landmark to be added are written in item 11, and in step 18, the new landmark ID (D15 ) In item 13 is conceivable.

[2-2. Display of Edited Display Graphic] When roads and landmarks are displayed based on the map database, a processing procedure as exemplified in the flowchart of FIG. 4 is executed in order to reflect the contents of the editing described above. You.

That is, the display processing unit 212 determines the vehicle position based on the vehicle position calculated by the vehicle position calculation unit 211 based on the information from the various sensors 24 and the information such as the display scale obtained from the input unit 25. The map data including the coordinates around the vehicle position is read from the map database and temporarily stored in the RAM 22.
(Step 20). In addition,
The map data read at this time includes not only data representing the position, width, structure, and the like of the road, but also a landmark ID group (denoted as D21) of landmarks to be displayed on the map.

Subsequently, FIG. 3 stored in the RAM 22
From the landmark information table (step S2), a data group (denoted as D22) relating to landmarks located within the range of the map read in step 20 is extracted (step 2).
1). Then, the loop processing is repeated using the variable i as a control variable the same number of times as the number of data of the data group D22 extracted in this manner, and the following processing is performed in the loop.

That is, first, any data in the data group D22 is compared with the landmark ID group D21 read from the map database, and it is checked whether or not there is one having the same longitude and latitude (step 22). Here, the data in the data group D22 to be compared is replaced with the variable i each time the loop is repeated.
Or, it is represented as data i. And as a result of such a comparison,
If there is one with the same latitude and longitude, landmark ID group D
The corresponding landmark ID group among 21 is D23.

If there are a plurality of landmark IDs included in the corresponding landmark ID group D23 (step 23), the old landmark ID 12 of the data i (FIG. 3) and the corresponding landmark ID group D23 The included landmark IDs are compared to search for a match (step 24).

As a result of this comparison, if there is no match, the process proceeds to the end of the loop, and the next data i is determined. When there is only one corresponding landmark ID in step 23, and in step 24, If there is a matching landmark ID, the landmark I
D is being edited. Therefore, the new landmark ID included in the data i is written in the work area of the RAM 22 (step 25) by replacing the landmark ID with the unique landmark ID (step 23) or the coincident landmark ID (step 24).

It should be noted that in step 22, there is no one having the same latitude and longitude, and the old landmark ID 12
Indicates that there is no landmark (step 26), since the data i represents a landmark newly added by editing, the new landmark ID 13 of the data i is stored in the landmark ID group D21. Newly added to the work area of the RAM 22 (step 2
7).

When the loop processing of the above contents is completed for all data i, the RAM 22 is ready with display graphic information reflecting the edited contents. Based on this display graphic information, Display 27
Display the map above. More specifically, for example, each landmark ID is associated with a table of stylized image data such as a brand mark, a company symbol, a police box, a station, and a school prepared in advance in the ROM 23. The image data corresponding to the landmark ID may be displayed on the display 27 by referring to this table.

When a map is displayed in the form of a bird's-eye view, landmarks such as buildings may be displayed in an approximate shape according to the viewpoint position.

[3. Effect) As described above, in this embodiment, when the user notices that the displayed graphic such as a landmark is different from the actual road condition, or wants to display a personal mark, Editing such as adding a new landmark at a desired position, changing or deleting a desired landmark can be performed. This makes it possible to change the display graphics such as landmarks included in the map information as fixed data according to the latest current situation, and to provide navigation technology that is highly reliable, secure, and easy to use. Can be provided.

In this embodiment, editing can be performed easily by a natural flow operation of specifying a position with a pointing device such as a joystick and performing an editing operation, thereby improving the editing efficiency. Further, in the present embodiment, a display graphic can be added at a specified position at the time of addition by simply specifying addition, change, or deletion as the type of editing, and the nearest display graphic can be added at the time of change or deletion. Since the data is to be edited, the editing can be performed efficiently.

The following example can be given as a specific example to which this embodiment is applied. For example, when the user drives a certain route, the landmark C
It is assumed that the bank store has actually been changed to the bank S store. In this case, the user designates the position of the relevant bank C, selects “change”, and selects the symbol mark or name of bank S from the list on the display screen. The symbol mark will be displayed.

Similarly, for example, a new convenience store mark can be added on the map, or a gas station mark that has been withdrawn can be deleted so as not to be displayed. Usability can also be improved by adding such a target with a mark such as a predetermined star.

In this embodiment, even if the display graphic information before editing is stored in a non-rewritable first storage medium such as a ROM or a CD-ROM, the contents of the editing are stored in a memory with a battery backup. Can be stored in a second storage medium such as. And when displaying,
