Abstract

The present invention provides the simple operation for displaying the information that is expected to be necessary for the user and the simplified procedure of the hands-free operation when displaying the map information on the screen. The display device 20 in which an arrangement state of the screen can be selected between a first state and a second state displays on the screen the detailed information of a destination or its surrounding area such as parking lot information, an access route guide to the transportation facilities, and information of the facility of the destination is displayed on the screen if a change of the arrangement of the screen is detected, if the destination has been set in advance, and if a distance between a current position and the destination is within a predetermined distance. Further, it comprises a display control means 27 for displaying at least a portion of the information acquired by the information acquisition means 23 if the change in the arrangement state of the screen is detected after the external equipment detection means 25 detected the connection of the external equipment 4.

Claims

1. A guide display device comprising:

a current position acquisition unit configured to acquire a current position;

a destination storage unit configured to store a destination;

a display unit configured to display an image;

a display control unit configured to control a display content; and

an arrangement change detection unit configured to detect that an arrangement of a screen of the display unit has been changed,

wherein the display control unit causes the display unit to display detailed information of the destination or its surrounding area if the arrangement of the screen is changed under a state where a distance between the current position and the destination is less than a predetermined distance.

2. The guide display device according to claim 1, wherein the display unit displays map information.

3. The guide display device according to claim 1, wherein the display control unit causes the display unit to display information of a facility of the destination or its peripheral facility as the detailed information.

4. The guide display device according to claim 3, wherein, if the destination is a facility of transportation facilities or if there is a facility of transportation facilities around the destination, the display control unit causes the display unit to display information of an access route to the facility as the detailed information.

5. The guide display device according to claim 1 further comprising a unit configured to determine what transportation is used.

6. The guide display device according to claim 5, wherein, if the transportation is a vehicle, the display control unit causes the display unit to display information of a parking lot and, otherwise, to display information of a facility of the destination or its peripheral facility.

7. The guide display device according to any one of claims 1 to 5, the detailed information of the destination or its surrounding area is information stored in the storage unit together with the map information and/or information downloaded by using a communication unit.

11. The display device according to claim 2, wherein the predetermined image information is image information of a keyboard.

8. A guide display method for displaying guide information on a screen, the method comprising the step of:

displaying detailed information of a destination or its surrounding area on the screen if a change in an arrangement of the screen is detected, if the destination has been set in advance, and if a distance between a current position and the destination is less than a predetermined distance.

9. A display device in which an arrangement state of the screen can be selected between a first state and a second state, the display device comprising:

an external equipment detection unit configured to detect a connection of external equipment;

an information acquisition unit configured to acquire information from the external equipment if the external equipment detection unit detects the connection of the external equipment;

a screen state detection unit configured to detect whether the arrangement state of the screen is in the first state or the second state; and

a display control unit configured to display at least a portion of the information acquired by the information acquisition unit if the change in the arrangement state of the screen is detected by the screen state detection unit after the external equipment detection unit detected the connection of the external equipment.

10. The display device according to claim 9,

wherein the external equipment is a portable telephone device, and

wherein the display control unit displays predetermined image information on the screen if a calling operation of the portable telephone device has not been made and the change in the arrangement state of the screen is again detected by the screen state detection unit after at least a portion of the information acquired by the information acquisition unit was displayed on the screen.

12. The display device according to any one of claims 9 to 11, wherein the display control unit prohibits the display of the information acquired by the information acquisition unit if there is no predetermined operation input even if the change in the arrangement state of the screen is detected by the screen state detection unit after the external equipment detection unit detected the connection of the external equipment.

13. A method for switching a display content for use in a display device in which an arrangement state of the screen can be selected between a first state and a second state, the method comprising the steps of:

detecting a connection of external equipment;

acquiring information from the external equipment if the connection of the external equipment is detected;

detecting whether the arrangement state of the screen is in the first state or the second state; and

displaying at least a portion of the information acquired by the step of acquiring, if the change in the arrangement state of the screen is detected after the connection of the external equipment was detected.

14. The method according to claim 13, wherein the display of the information acquired by the step of acquiring is prohibited if there is no predetermined operation input even if the change in the arrangement state of the screen is detected after the connection of the external equipment was detected.

15. A program, when installed in an information processing device, instructing the information processing device to perform a function as a display device in which an arrangement state of a screen can be selected between a first state and a second state, the program configured to implement:

an external equipment detection function for detecting a connection of external equipment;

an information acquisition function for acquiring information from the external equipment if the external equipment detection function detects the connection of the external equipment;

a screen state detection function for detecting whether the arrangement state of the screen is in the first state or the second state; and

a display control function for displaying at least a portion of the information acquired by the information acquisition function if the change in the arrangement state of the screen is detected by the screen state detection function after the external equipment detection function detected the connection of the external equipment.
