2. Description of the Related Art A navigation device which guides a vehicle so that a driver can easily reach a desired destination detects a position of the vehicle and stores the position of the vehicle around a vehicle position from a storage medium such as a CD-ROM. The map data is read out, the map image is displayed on the display screen, and a vehicle position mark (own vehicle mark) is superimposed and displayed at a predetermined location on the map image. Then, as the current position changes due to the movement of the vehicle, the own vehicle mark on the display screen moves,
Alternatively, the vehicle mark is fixed at a predetermined position such as the center of the display screen or the like, and the map is scrolled so that the map information around the vehicle position can always be understood at a glance.

Such a navigation device has a route guidance function for inputting a destination, searching for a guidance route from a departure point to a destination, displaying the guidance route on a display screen, and guiding the driver to travel. In addition, the navigation device has a genre-based destination search function for selecting a desired genre from a genre list such as a station or a hot spring, and then searching for a desired destination from a destination name list of the genre.

FIG. 5 is an explanatory diagram of a conventional genre-based destination search function. When you press the menu key on the remote control,
The navigation device has a main menu M on the map MP.
Display MN and submenu SMN. Next, when the item "Search" of the main menu MMN is selected using the joystick key, the navigation control device displays a submenu SMN of the item "Search" (FIG. 5).
(A)). In this submenu SMN, "By genre"
Since there is an item, when the item is selected using the joystick key, the navigation device displays a pre-categorized genre list as shown in FIG. 5B.
Note that genre names that cannot be displayed on one screen can be displayed by scrolling. When a hot spring is selected in such a state, the navigation device reads data of all hot springs from the database and displays a list of hot spring names (FIG. 5).
(C)). The remaining hot spring names that cannot be displayed at once can be displayed by scrolling. In such a state,
When Iwaki-Yumoto Onsen is selected, the navigation device displays a map around the Iwaki-Yumoto Onsen and a cursor CR on the Iwaki-Yumoto Onsen as shown in FIG. The menu item MNA of point / point registration / current location is displayed. In this state, when the destination is selected and the enter button is pressed, the Iwaki-Yumoto hot spring can be set as the destination. That is, by the above-described genre-based destination search function, a desired genre can be selected, and a desired destination can be searched from a destination name list of the genre.

[0005]

The genre-based destination search function displays all genres and destinations classified in advance regardless of time. However, depending on the destination, there are times when it is suitable for sightseeing, such as sightseeing spots. When searching for sightseeing spots, displaying the sights of autumn leaves in April in spring or the sights of cherry blossoms in October in autumn is This information is unnecessary for the user and may be confusing when searching for a desired tourist spot.

Accordingly, an object of the present invention is to provide a sightseeing spot search method for a navigation device that can easily search for a desired sightseeing spot by performing a sightseeing spot search in consideration of a period suitable for sightseeing. It is in.

[0007]

According to the present invention, according to the present invention, a name, a position, and a period suitable for sightseeing are stored in advance for a sightseeing spot, a time is set at the time of search, and the time is set. This is achieved by creating and displaying a list of tourist destination names based on time and a period suitable for sightseeing. Thus, the user can easily search for a sightseeing spot suitable for the set time.

Further, according to the present invention, the above-mentioned object is achieved by creating and displaying a list of sightseeing spots for each selected genre. Thus, the user can easily search for a desired tourist spot.

Further, according to the present invention, the above-mentioned object is achieved by automatically setting the date at the time of retrieval. Thus, the user can easily search for a sightseeing spot suitable for sightseeing at present.

(B) Sightseeing spot information FIG. 2 is an explanatory diagram of sightseeing spot information stored in the storage medium 11. The storage medium 11 stores sightseeing spot information in addition to the road layer, the background layer, and the character / symbol layer. As shown in FIG. 2, the sightseeing spot information is composed of sightseeing spot names, positions (coordinates and latitudes), and timings (tourism periods) for each categorized sightseeing genre such as a ski resort or a fireworks display. For example, if you search in January,
Ski resorts that include January in the season (sightseeing period) are searched.

(C) Processing Flow FIG. 3 is a processing flow at the time of searching for a tourist spot according to the present invention. Using the remote controller 16, select the submenu item "sightseeing spot" of the main menu item "search" (step 101:
Referring to FIG. 4A), the CPU 18 checks the current date from the calendar unit 26 (step 102). Then
