FIG. 2 is a diagram showing a display example of the registration information output device 12 in the navigation system of this embodiment.

In the navigation system of this embodiment,
As shown in FIG. 2, information such as a well-known spot found by the user during the drive is displayed at the position on the map, the user layer 20 (symbol mark 21, registration name 22), and detailed information linked to it are provided in the information registration unit Register at 161.

In the information registration of the present embodiment, the user layer 20 is registered in the location shown in FIG. 2, and as the detailed information linked to it, the privacy information such as the event at that time is registered in characters, images, voices, and the like. To do.

Next, the processing in the information registration will be described with reference to FIGS. 3 and 4.

FIG. 3A is a diagram showing a display example of the output device 12 at the time of information registration, and FIG. 3B shows a data structure of the registration information stored in the auxiliary storage device 15. It is a figure.

FIG. 4 is a flow chart showing a processing procedure at the time of information registration in the navigation system of this embodiment.

In the processing procedure at the time of information registration in the navigation system of this embodiment, the user first determines the registration position by using the input device 13 such as a mouse (step 401).

The symbol mark 21 to be registered is determined, and the registration name 22 is input (step 402). The registered name 22 is used as a search key when searching. The detailed data linked to the user layer 20 is the input device 13
Character data 34, image data 31, voice data 3 on the detailed information screen of FIG. 3A displayed by an action such as double-clicking the user layer 20 using
The detailed information such as 2 is input (step 403).

The concealment target check box 33 shown in FIG. 3 (a) is referred to as a criterion for concealment execution, and when the concealment target is selected, the concealment target check box 33 is turned on.
If it is excluded from the concealment target, it is turned off (step 404).

The data structure of the registration information input in this way is, as shown in FIG. 3B, a registration position 301 consisting of coordinates on a map, a symbol mark code 302, a registration name 303, character data 304, Image data 305,
The audio data 306 and the concealment flag 307 are stored in the auxiliary storage device 15.

This concealment flag 307 becomes "1" when the concealment target check box 33 in the input display example shown in FIG. 3 is ON, and "0" is stored when it is OFF, and this concealment flag is "1". The registration information of is subject to concealment and is not subject to search. Incidentally, when it is desired to refer to the detailed information later, the user layer 20 is double-clicked as in the previous case.

When the user wants to hide the registration information, the registration information confidential section 162 of the control device 16 is used.

Next, the procedure of concealing registration information by the registration information confidential section 162 will be described with reference to the flowchart of FIG.

First, when the user activates the registration information confidential section 162 of the control device 16 from the input device 13, first, a screen prompting the registration of the password as the concealment lock is displayed on the output device 12, The user inputs the password from the input device 13 on this registration screen (step 501). The password input here is collated when the concealment is released. In other words, the key is locked with the password at the time of hiding, and the key is unlocked with the same password as at the time of hiding when unlocking.

When the input of the password is completed, the redisplay processing is executed (step 502).

In the redisplay processing of step 502, as shown in FIG. 6, the control device 16 first acquires the current position information from the receiving device 11 or the input device 13 (step 601).

After that, the map data of the corresponding area is retrieved from the auxiliary storage device 14 based on the position information (step 602), and the map is displayed on the output device 12 (step 603).

Next, the execution state of the concealment process is checked before displaying the registration information in the area (step 60).

If the concealment process is being executed, the registration information that is not to be concealed is acquired from the auxiliary storage device 15 by the concealment flag of each registration information (step 607), and the registration information is displayed on the output device 12 (step 606). ).

If the concealment process is canceled in step 604, all registration information in the area is acquired from the auxiliary storage device 15 (step 605) and the registration information is displayed on the output device 12 (step 606). ).

Since the user layer of the registration information hidden in this way is not displayed, even if the place where the user layer was located is displayed by scrolling the map, the user layer will not be visible.

Further, since the hidden registration information is excluded from the search target, it is not exposed to the public during the search.

Finally, regarding the procedure for canceling the concealment processing,
As shown in the flowchart of FIG. 7, the user uses the registration information confidential section 162 to enter the same password as that used when the concealment process is executed on the password input screen displayed on the output device 12 (step 701), and collates the keyword. Then, if they match (step 702), the above-mentioned redisplay processing of FIG. 6 is executed (step 703), and the cancellation processing is executed.
If they do not match, the concealment removal processing is not executed.

Therefore, as described above, confidential registration information cannot be displayed or output, and can be excluded from the search target. Scrolling the map near the registration point or
Since it is possible to prevent the confidential registration information from being exposed to the eyes without being involved in one's will with the movement of the vehicle position, it is possible to protect the confidentiality of the registration information.

Further, as shown in FIG. 8A, by providing a plurality of concealing groups (here, three),
The concealment of registration information can be grouped according to the purpose of use.

This is effective, for example, in the navigation system when the registration information is hidden for each person in the passenger seat who is to see the display together.

This concealment grouping is performed by checking the concealment group number check box 81 shown in FIG. 8A and collecting the registration information to be concealed for each person in the front passenger seat. The registration information consists of
As shown in FIG. 8B, a concealment group number 801 is added to that shown in FIG.

In this embodiment, the navigation system is taken up, but the same applies to other electronic map systems and the like.

Further, when it is inconvenient to set the concealment target individually, the usability is improved by providing a concealment / cancellation function collectively.
