Abstract

A map screen is displayed in a left half area of a display panel and an real image such as a satellite photograph depicting a surface of an earth and an aerial photograph is displayed in the remaining right half area thereof based on real image data. The real images on different scales (the image as the wide area display and the image as the detailed display) can be displayed in the right half area on the display panel. A default condition of two-screen display is set to display the real image as the wide area display in the right half-area.

Claims

1. A navigation apparatus, comprising:

a display unit on which first and second areas are defined; and

a display control unit which includes a first display control section and controls the display unit to display at least one of a map screen and a real image, based on map data, real image data, and a present location, wherein;

when a first instruction signal is input to the display control unit, the first display control section controls the display unit to display the map screen in the first area and the real image on one of first to n-th scales in the second area, where n is an integer not smaller than two.

2. The navigation apparatus according to claim 1, wherein the first area and the second area do not overlap each other.

3. The navigation apparatus according to claim 1, wherein the one of the first to n-th scales is smaller than the other scales.

4. The navigation apparatus according to claim 1, wherein when a second instruction signal is input to the display control unit, the first display control section changes the scale of the real image displayed in the second area.

5. The navigation apparatus according claim 1, wherein:

a third area is defined on the display unit;

the display control unit further includes a second display control section;

when a third instruction signal is input to the display control unit, the second display control section controls the display unit to display one of the map screen and the real image in the third area;

when the display unit displays the one in the third area and a fourth instruction signal is input to the display control unit, the second display control section changes the one of the map screen and the real image to the other.

6. The navigation apparatus according to claim 5, wherein the third area contains the first and second areas.

7. The navigation apparatus according to claim 5, wherein when the third instruction signal is input to the display control unit, the second display control section controls the display unit to display the real image on another of the first to n-th scales, which is different from the one of the first to n-th scales, in the third area.

8. The navigation apparatus according to claim 5, wherein when the display unit displays the real image in the third area and a fifth instruction signal is input to the display control unit, the second display control section changes the scale of the displayed real image.
