Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a navigation apparatus, and more particularly to a navigation apparatus that displays a road map on a display unit and displays landmarks indicating various facilities in an overlapping manner.
[0002]
[Prior art]
A navigation device that provides vehicle travel guidance so that a driver can reach a desired destination, detects the position of the vehicle, reads map data around the vehicle position from a storage medium such as a DVD-ROM, and maps An image is drawn on the display screen, and a vehicle position mark is drawn at a predetermined location on a landmark or map image representing various facilities.
[0003]
However, in the conventional navigation device, when a user wants to display a landmark on a map image, a menu screen for selecting a landmark is opened by several operation processes, and a desired landmark is selected from many landmarks. There is annoyance that must be done. In addition, if the user adds a desired landmark unnecessarily, many landmarks are displayed on the map image, and there is a problem that it takes time to search for the desired landmark. Furthermore, when a large number of landmarks are displayed, as shown in FIG. 7 , for example, a parking lot landmark near the same point and a gasoline station landmark overlap, which makes it difficult to see. There is also.
Accordingly, an object of the present invention is to provide a navigation device that allows a user to easily display / hide a desired landmark on a map image.
[0004]
[Means for Solving the Problems]
According to the present invention, the above-described problem is that, according to the present invention, display means for displaying a road map, storage means for storing landmarks indicating facilities, etc., and selection means for selecting landmarks stored in the storage means, A navigation device for displaying a landmark selected by the selection means at a predetermined position on a road map displayed by the display means, at least one preset key, and a land stored in the storage means Preset means capable of storing and reading out a plurality of types of desired landmarks collectively selected from marks corresponding to the preset keys, and a plurality of types displayed at predetermined positions on the road map by operating the preset keys is achieved by providing a landmark display and non-display can be switched to the display / non-display switching means That.

And a preset key 27a for presetting the landmark. 28 is a bus.
[0011]
(B) Data structure of landmark according to the first embodiment of the present invention FIG. 3 shows an example of the data structure of the landmark according to the first embodiment of the present invention. First, in the DVD-ROM 11, as shown in (a), the pointer 1 stores a type of landmark such as a convenience store and a type of 001, 002, 003, 004. Further, as shown in (b), a name and image data are stored for each type. For example, the type is 001, the name is Seven-Eleven, and the image data is IMG1. That is, it has a hierarchical structure. The landmark preset storage unit 20a stores a pointer corresponding to each preset key of the preset key 27a as shown in (c). For example, preset key No. Since 1 and 3 pointers correspond to 1, the convenience store of pointer 1 and the fast food landmark of pointer 3 correspond to the configuration shown in FIG.
[0012]
(C-1) Flowchart of preset operation of the first embodiment of the present invention FIG. 4 is a flowchart of the preset operation of the first embodiment of the present invention. The landmark currently displayed on the display device 27 corresponds to the preset key 27a. The process for making it memorize | store is shown.
First, the landmark preset control unit 20 determines whether or not the preset key 27a has been pressed for a predetermined time, for example, 5 seconds (step 101). If the preset key 27a has not been pressed for 5 seconds or more, it corresponds to the pressed preset key 27a. A landmark is displayed (step 102). On the other hand, if it is pressed, the processor 17 determines whether or not the current landmark display is on the display device 27 (step 103). If no landmark is displayed, the process ends. On the other hand, when the landmark is displayed, the landmark preset control unit 20 stores the displayed landmark in the landmark preset storage unit 20a in association with the preset key 27a (step 104).
[0013]
(C-2) Flowchart of Preset Key Pressing Operation of the First Embodiment of the Present Invention FIG. 5 is a flowchart of the preset key pressing operation of the first embodiment of the present invention. The landmark corresponding to the preset key 27a is displayed on the map image. Shows the processing to be displayed.
First, the landmark preset control unit 20 determines whether or not the preset key 27a has been pressed (step 201). If not, the landmark preset control unit 20 stands by without performing any processing. On the other hand, when the preset key 27a is pressed, it is confirmed which number of the preset key is pressed (step 202). Next, the processor 17 confirms the land number corresponding to the preset key number confirmed on the display device 27. It is determined whether or not a mark is displayed (step 203). Then, if not displayed, the landmark preset switching unit 20b reads the landmark corresponding to the pressed preset key 27a from the landmark preset storage unit 20a, switches to the read landmark, and displays it on the display device 27. (Step 204). On the other hand, when the landmark is displayed, the landmark control unit 20 determines whether or not the pressed preset key 27a is a preset key corresponding to the currently displayed landmark (step 205). If there is no key, the process of step 204 is performed. On the other hand, in the case of the corresponding key, the landmark control unit 20 hides the currently displayed landmark (step 206).
[0014]
(B) Second embodiment of the present invention (a) Flow chart of preset operation of the second embodiment of the present invention FIG. 6 is a flowchart of the preset operation of the second embodiment of the present invention, which is currently displayed on the display device 27. A process for storing a plurality of types of landmarks other than the landmarks in correspondence with the preset key 27a is shown. The navigation device has the same configuration as that shown in FIG. 3, and the landmark data configuration is the same as that shown in FIG.
[0015]
First, the menu screen "change" from (FIG. 8 (a)) is selected, then the menu screen displayed "Display Genre Change" from (FIG. 8 (b)) is selected to select the desired landmark When that, as shown in FIG. 8 (c), a selection screen for selecting a desired landmark is displayed.
[0016]
Next, the processor 17 determines the desired landmark selection screen (Fig. 8 (c)) from a plurality of types of landmark, for example, whether the selected at once and convenience store and a gas station (step 301 ) If not selected, the process waits without performing any processing. On the other hand, if it is selected by the collective, landmark convenience store and a gas station that is selected (FIG. 8 (d)) is displayed on the display device 27 (step 302). Next, the landmark preset control unit 20 determines whether or not the preset key 27a has been pressed for a predetermined time, for example, 5 seconds (step 303). On the other hand, when pressed, the landmark preset control unit 20 stores the convenience store and the gas station landmarks collectively selected in the landmark preset storage unit 20a in association with the preset key 27a (step 304).
In the embodiment, the preset key 27 a is provided on the display device 27, but the preset key may be provided on the remote controller 15.
[0017]
【The invention's effect】
As described above, according to the present invention, there is provided display means for displaying a road map, storage means for storing landmarks indicating facilities and the like, and selection means for selecting landmarks stored in the storage means. In the navigation apparatus for displaying the landmark selected by the selection unit at a predetermined position on the road map displayed by the display unit, at least one preset key and a landmark stored in the storage unit Preset means capable of storing and reading out a plurality of types of desired landmarks collectively selected from among the preset keys, and a plurality of types of lands displayed at predetermined positions on the road map by operating the preset keys since a possible and the display / non-display switching means hides the mark, the user status More plurality of types of desired landmarks readily display / non-display on the map image.
