Send to. In response to the input of the current location data, the CPU 3 searches the RAM 4 based on the current location data, and from all the divided areas of the map data stored in the RAM 4, includes the current location (B town). Is selected.

  As a method of searching for a divided area, the numerical value (= 5.7 °) obtained by subtracting the starting latitude (= 30 °) of the map from the latitude of the current location (= 35.7 °) is subtracted into one divided area. Is divided by the length in the parallel direction (= 2/3 °), and the numerical value (= 8.55) obtained by the division is rounded down. The numerical value (= 8) obtained in this way is a numerical value indicating the number of divided areas from the starting point divided area (hatched divided area in FIG. 2) in the latitude direction.

  Also, the starting point longitude (= 128 °) of the map is subtracted from the longitude (= 139.7 °) of the current location, and the numerical value (= 11.7 °) obtained by subtraction is the length in the meridian direction of one divided area. Divide by (= 1 °) and round down the decimal point of the numerical value (= 11.7) obtained by the division. The numerical value (= 11) thus obtained is a numerical value indicating the number of divided areas from the start point divided area (hatched divided area in FIG. 2) in the meridian direction. When the current location is “(latitude = 35.7 °, longitude = 139.7 °)”, the eighth divided area from the start point divided area in the latitude direction and the eleventh divided area from the start point divided area in the meridian direction Become. In this way, since the divided area including the current location is searched by the calculation formula using the current location data (latitude / longitude), the current location data and all the divided areas (456) are compared to include the current location. The time required for the search can be shortened as compared with the search for the divided area.

  When the search for the divided area is completed, the CPU 3 next searches for the landmark. At this time, the CPU 3 searches for the landmark only in the divided area A (11, 8) searched (selected) as described above. In the present embodiment, the CPU 3 also functions as current location facility data search means for searching facility data including position data acquired by the GPS unit 7 from the RAM 4.

  The CPU 3 searches for landmarks in the divided area A (11, 8) and selects an LM area including the current location. In the present embodiment, the B town LM area is selected as the search result.

  When the CPU 3 selects the LM area including the current location, the CPU 6 displays a map around the selected LM area (B town LM area) on the LCD 6 and displays an icon indicating the current location on the map. In this state, when the user operates the destination setting button of the operation unit 5 to set “F amusement park” as the destination, the route search unit 8 travels from the town B to the F amusement park. Search for. When the route search by the route search unit 8 ends, the CPU 3 displays the travel route from the B town to the F amusement park on the map displayed on the LCD 6 (see FIG. 6).

  Then, after displaying the travel route, the CPU 3 reproduces the music data of the music (“Rain B town”) stored in the related music section of the current location (B town) of the landmark data table, and the speaker 10 (FIG. 1)). In this embodiment, CPU3 functions also as a music input means which selects and inputs the music data linked | related with the facility data of the present location (B town) from RAM4.

  Before reproducing the music data of the music (“Rain B Town”) associated with the LM area including the current location data, the CPU 3 inputs a scenario generation signal to the scenario generation device 9 (see FIG. 1). In response to the input of the scenario generation signal, the scenario generation device 9 analyzes the feature quantity of the music (“Rain B Town”) to be reproduced by the CPU 3 by a known analysis method. The scenario generation device 9 calculates an accent portion based on the analysis result and divides the music into a plurality of components. In the present embodiment, the scenario generation device 9 divides eight beats from the beginning of a beat as one component, switches an image to be displayed on the LCD 6 for each component of eight beats, and zooms in / out the image at the accent portion.

The image is switched, and control for zooming in / out the image at the accent portion is performed. Thus, a moving image can be reproduced by continuously switching the image displayed on the LCD 6 every 8 beats. In addition, CPU3 displays only the image of B town on LCD6, without displaying the map around the present location, and a driving | running route. Further, the display of the image on the LCD 6 by the CPU 3 is performed in the order of the number of image data of B towns for 100 sheets. For this reason, numbers from 1 to 100 are assigned to 100 image data of town B stored in the landmark data table.

  The CPU 3 runs on the LCD 6 immediately before reaching the point PA (see FIG. 6) where the user needs to turn the road in order to travel to the destination F amusement park (for example, 700 m before). The route is displayed and the image display of town B is temporarily stopped. Then, after the automobile driven by the user turns around the point PA (for example, after passing 100 m), the CPU 3 resumes the image display of the B town on the LCD 6. As a result, an image of the current location (town B) is displayed while traveling on a straight road that does not require navigation of the travel route, and a travel route is displayed when traveling on a point PA that requires navigation of the travel route. It is possible to display an image of the current location (town B) without affecting (interfering with) the navigation of the travel route. The above numerical values of 700 m and 100 m can be appropriately changed.
