Abstract

A display input device is comprised of a touch panel 1 for carrying out a display of an image and an input of an image, a vibration sensor (a proximity sensor 12) for detecting a vibration of an object to be detected which is positioned opposite to the touch panel 1, a vibration correcting unit 304 for making a vibration correction when the vibration of the object to be detected which is detected by the vibration sensor has an amount equal to or larger than a predetermined amount, and a control unit 3 for carrying out a process of transforming an image in a display area having a fixed range displayed on the above-mentioned touch panel according to the position of the object to be detected to which the above-mentioned vibration correction has been made.

Claims

1. A display input device comprising:

a touch panel for carrying out a display of an image and an input of an image;

a vibration sensor for detecting a vibration of an object to be detected which is positioned opposite to said touch panel on a basis of a change in a position of the object to be detected;

a vibration correcting unit for making a vibration correction to remove a vibration component from the change of the position of said object to be detected when the vibration of the object to be detected which is detected by said vibration sensor has an amount equal to or larger than a predetermined amount; and

a control unit for carrying out a process of transforming an image in a display area having a fixed range displayed on said touch panel according to the position of the object to be detected to which the vibration correction has been made.

2. The display input device according to claim 1, wherein said vibration sensor is a proximity sensor for detecting the vibration of the object to be detected, which is positioned opposite to said touch panel, in a non-contact manner.

3. The display input device according to claim 1, wherein said control unit makes said vibration correction by performing a filtering process with a predetermined cut-off frequency on a waveform of the vibration of said object to be detected.

4. The display input device according to claim 1, wherein said control unit makes said vibration correction by performing a predetermined filtering process on a waveform of the vibration of said object to be detected.

8. The display input device according to claim 3, wherein said control unit changes intensity of the vibration correction according to filter characteristics which are predetermined dependently upon a type of the image in the display area having the fixed range displayed on said touch panel.

9. The display input device according to claim 4, wherein said control unit changes intensity of the vibration correction according to filter characteristics which are predetermined dependently upon a type of the image in the display area having the fixed range displayed on said touch panel.

10. The display input device according to claim 3, wherein said control unit detects a vertical distance of the object to be detected, which is positioned opposite to said touch panel, by using said vibration sensor, and changes intensity of the vibration correction according to filter characteristics which are determined dependently upon said vertical distance.

11. The display input device according to claim 4, wherein said control unit detects a vertical distance of the object to be detected, which is positioned opposite to said touch panel, by using said vibration sensor, and changes intensity of the vibration correction according to filter characteristics which are determined dependently upon said vertical distance.

5. A display input device comprising:

a touch panel for carrying out a display of an image and an input of an image;

a vibration sensor for detecting a vibration of an object to be detected which is positioned opposite to said touch panel on a basis of a change in a position of the object to be detected;

an external sensor for detecting a state of a vehicle;

a vibration correcting unit for making a vibration correction to remove a vibration component from the change of the position of said object to be detected when said external sensor determines that the vehicle is running;

a control unit for carrying out a process of transforming an image in a display area having a fixed range displayed on said touch panel according to the position of the object to be detected to which the vibration correction has been made.

6. The display input device according to claim 5, wherein said external sensor includes a speed sensor for detecting a speed of said vehicle, and an acceleration sensor for detecting a vibration while said vehicle is running.

7. The display input device according to claim 6, wherein said control unit changes intensity of the vibration correction according to filter characteristics which are determined dependently upon the vehicle speed detected by said speed sensor or the vibration detected by said acceleration sensor.
