Abstract

A display input device is comprised of a touch panel 1 for carrying out a display of information and an input of information, a vibration detection sensor (proximity sensors 12 or an acceleration sensor 23) for detecting a vibration of an object to be detected which is positioned opposite to the touch panel 1, and a control unit 3 for, when it is determined that a relative vibration between the touch panel and the object to be detected, which is detected by the vibration detection sensor, has an amount equal to or larger than a predetermined amount, carrying out a process of enlarging an image in a display area having a fixed range, which is displayed on the touch panel 1, to display the enlarged image.

Claims

1-8. -8. (canceled)

9. A display input device comprising:

a touch panel for detecting an approach of an object to be detected in a non-contact manner, and for carrying out an input of information and a display of an image;

a vibration detection sensor for detecting a vibration of said object to be detected which is positioned opposite to said touch panel; and

a control unit for, when it is determined that a relative vibration between said touch panel and the object to be detected, which is detected by said vibration detection sensor, has an amount equal to or larger than a predetermined amount, carrying out a process of enlarging an image in a display area having a fixed range, which is displayed on said touch panel, to display the enlarged image.

10. The display input device according to claim 9, wherein said display input device includes a running detecting unit for detecting a running state of a vehicle, and, when it is determined that the relative vibration between said touch panel and the object to be detected has an amount equal to or larger than the predetermined amount and said running detecting unit detects that the vehicle is stopped, said control unit carries out a process of enlarging the image in the display area having the fixed range which is displayed on said touch panel, or when said running detecting unit detects that the vehicle is running, said control unit carries out a process of enlarging the image to a further larger size by increasing a scale of enlargement compared with that used in said enlarging process to display the enlarged image.

11. The display input device according to claim 9, wherein when a horizontal vibration having the predetermined amount or more of the object to be detected, which is positioned opposite to said touch panel, with respect to a surface of said touch panel is detected, said control unit carries out the process of enlarging a content in the display area having the fixed range, which is displayed on said touch panel, to display the enlarged image, whereas when a vertical vibration having the predetermined amount or more of the object to be detected with respect to a surface of said touch panel is detected, said control unit carries out a process of reducing the content in said display area having the fixed range to display the reduced content.

12. The display input device according to claim 9, wherein said control unit changes a scale of enlargement according to the vibration amount detected by said vibration detection sensor, and carries out the process of enlarging the content in the display area having the fixed range, which is displayed on said touch panel, to display the enlarged content.

13. The display input device according to claim 9, wherein said vibration detection sensor includes a proximity sensor for detecting the relative vibration between said touch panel and the object to be detected in a non-contact manner.

14. The display input device according to claim 9, wherein said vibration detection sensor includes an acceleration sensor for detecting acceleration information.

15. The display input device according to claim 9, wherein said vibration detection sensor includes a proximity sensor for detecting the relative vibration between said touch panel and the object to be detected in a non-contact manner, and an acceleration sensor, and said control unit calculates the relative vibration between said touch panel and the object to be detected from a vibration status from said proximity sensor and a vibration status shown by acceleration information detected by said acceleration sensor.

16. The display input device according to claim 9, wherein said control unit stores data about the vibration detected by said vibration detection sensor in a time series during a predetermined time period, and, when an error from an average calculated by extracting a predetermined frequency component from said time-series data has a predetermined value or more, determines that the relative vibration has an amount equal to or larger than the predetermined amount.

17. A navigation device which can be connected to a touch panel for carrying out an input of information and a display of an image, said touch panel having a vibration detection sensor for detecting an approach of an object to be detected in a non-contact manner and also detecting a vibration of said object to be detected, said navigation device comprising:

a control unit for, when it is determined that a relative vibration of said object to be detected, which is inputted from said touch panel, has an amount equal to or larger than a predetermined amount, carrying out a process of enlarging an image in a display area having a fixed range which is displayed on said touch panel and outputting the image enlarged thereby to said touch panel,

wherein said control unit outputs said image to said touch panel according to the information detected by said vibration detection sensor and the process carried out thereby.
