Abstract

This disclosure provides an information display device. The information display device includes an acquirer for acquiring positional information on one or more display targets including at least one of a landmark serving as a reference mark used when a movable body is in move, another movable body, and a location registered by an operator, and a controller for displaying positional information and circumferential information on the movable body in an information display area, associating at least one of the one or more display targets of which a position is outside the information display area with a direction to which the at least one of the one or more display targets is located centering on the movable body, and displaying the at least one of the one or more display targets in an outer circumferential area of the information display area.

Claims

1. An information display device, comprising:

an acquirer for acquiring positional information on one or more display targets including at least one of a landmark serving as a reference mark used when a movable body is in move, another movable body, and a location registered by an operator; and

a controller for displaying positional information and circumferential information on the movable body in an information display area, associating at least one of the one or more display targets of which a position is outside the information display area with a direction to which the at least one of the one or more display targets is located, and displaying the at least one of the one or more display targets in an outer circumferential area of the information display area.

2. The information display device of claim 1, wherein the display target to be displayed in the outer circumferential area of the information display area is determined based on a predetermined display condition.

3. The information display device of claim 2, wherein the display condition includes a distance from a position corresponding to the center of the information display area to the display target in the display condition.

4. The information display device of claim 2, wherein the display condition includes a direction to which the display target is located with respect to a position corresponding to the center of the information display area.

5. The information display device of claim 2, wherein the display condition includes a kind of the display target.

6. The information display device of claim 2, wherein the display condition includes a first display condition for not displaying the display target that is currently displayed, and a second condition for displaying the display target that is currently not displayed, the second condition being different from the first display condition.

7. The information display device of claim 1, wherein a display manner of the display target to be displayed in the outer circumferential area of the information display area is changed based on a distance of the display target from a position corresponding to the center of the information display area.

8. The information display device of claim 7, wherein the display manner includes at least one of size, color and transparency of the display target to be displayed in the outer circumferential area of the information display area.

9. The information display device of claim 1, further comprising a user interface for allowing the operator to select the display target displayed in the outer circumferential area of the information display area, wherein the controller displays the distance from a position corresponding to the center of the information display area for the display target selected by the user interface.

10. The information display device of claim 1, further comprising a user interface for allowing the operator to change a state of the display target between displayed and not displayed and at least one of size, color and transparency of the display target.

11. The information display device of claim 1, further comprising a display target information storage for storing a terrestrial reference position of the landmark in advance.

12. The information display device of claim 1, wherein the display target other than the at least one of the one or more display targets of which the position is outside the information display area is displayed in the information display area.

13. A radar apparatus carried in a ship and having a radar antenna, comprising:

an acquirer for acquiring positional information on one or more display targets including at least one of a landmark serving as a reference mark used when a movable body is in move, another movable body, and a location registered by an operator; and

a controller for displaying positional information and circumferential information on the movable body in an information display area, associating at least one of the one or more display targets of which a position is outside the information display area with a direction to which the at least one of the one or more display targets is located, and displaying the at least one of the one or more display targets in an outer circumferential area of the information display area,

wherein the display target is displayed in the information display area so as to be superimposed on a radar image.

14. A method of displaying information, comprising:

acquiring positional information on one or more display targets including at least one of a landmark serving as a reference mark used when a movable body is in move, another movable body, and a location registered by an operator; and

displaying positional information and circumferential information on the movable body in an information display area, associating at least one of the one or more display targets of which a position is outside the information display area with a direction to which the at least one of the one or more display targets is located, and displaying the at least one of the one or more display targets in an outer circumferential area of the information display area.
