Abstract

When setting a spot by designating a desired position on a map displayed on a display unit, a spot setting menu picture is displayed in the vicinity of the designated position, thereby improving the visibility of a positional relation to improve operability. A navigation device (1) is provided with an input unit (13) which designates a spot on the displayed map, a spot position detection unit (16) which identifies the spot designated by the input unit (13), a menu display position determination unit (17) which determines the display position of the menu picture (38) for selecting an item for setting the spot identified by the spot position detection unit (16), and a mark display unit (18) which displays a spot setting mark (36) which indicates a touch-operated position on a display screen. The menu display position determination unit (17) detects the display position of the spot setting mark (36) and determines the display position of the menu picture (38) in accordance with the display position of the spot setting mark (36).

Claims

1. A navigation device comprising:

an input unit which designates a location on a map displayed on a display unit;

a location position detection unit which identifies the location designated by the input unit;

a menu display position determination unit which determines a display position of a menu image used to select an item for setting the location identified by the location position detection unit; and

a mark display unit which displays a location setting mark pointing at the designated location,

wherein the menu display position determination unit detects a display position of the location setting mark and determines the display position of the menu image in accordance with the display position of the location setting mark.

2. The navigation device according to claim 1, wherein the menu image is displayed in a pop-up dialogue box emerging from the location setting mark.

3. The navigation device according to claim 1, wherein

a display screen of the display unit has a display region segmented into a predetermined number of regions, and

the menu display position determination unit detects one of the regions, in which the location setting mark is displayed, and determines to dispose the menu image in proximity to the location setting mark, on a side of another of the regions, which is opposed to and is in a vertical or horizontal direction with respect to the detected one of the regions.

4. The navigation device according to claim 1, wherein

the menu display position determination unit detects the display position of the location setting mark, and

dividing a display screen by a plurality of straight lines intersecting at the detected display position of the location setting mark, the menu display position determination unit determines the display position of the menu image in consideration of areas of individual regions obtained by dividing the display screen.

5. The navigation device according to claim 4, wherein the menu display position determination unit determines a region having the largest area, among the individual regions obtained by dividing the display screen, as a region including the display position of the menu image.

6. The navigation device according to claim 2, wherein

a display screen of the display unit has a display region segmented into a predetermined number of regions, and

the menu display position determination unit detects one of the regions, in which the location setting mark is displayed, and determines to dispose the menu image in proximity to the location setting mark, on a side of another of the regions, which is opposed to and is in a vertical or horizontal direction with respect to the detected one of the regions.

7. The navigation device according to claim 2, wherein

the menu display position determination unit detects the display position of the location setting mark, and

dividing a display screen by a plurality of straight lines intersecting at the detected display position of the location setting mark, the menu display position determination unit determines the display position of the menu image in consideration of areas of individual regions obtained by dividing the display screen.
