Abstract

An input device includes a touch panel; a coordinate detection unit which detects coordinates of input to the touch panel; and a coordinate processing unit which performs a correction processing for detected input coordinates. In the correction processing, the coordinate processing unit corrects first coordinates input to a correction region formed on an inner side of an end portion of the touch panel to second coordinates in an input disabled region formed within the end portion of the touch panel or in the correction region, based on a distance between the input disabled region and the first coordinates.

Claims

1. An input device comprising:

a touch panel;

a coordinate detection unit which detects coordinates of input to the touch panel; and

a coordinate processing unit which performs a correction processing for input coordinates detected by the coordinate detection unit;

wherein, in the correction processing, the coordinate processing unit corrects first coordinates input to a correction region formed on an inner side of an end portion of the touch panel to second coordinates in an input disabled region formed within the end portion of the touch panel or in the correction region, based on a distance between the input disabled region and the first coordinates.

2. The input device according to claim 1,

wherein the coordinate processing unit performs the correction processing such that a distance between an edge of the touch panel and the second coordinates becomes shorter as the distance between the input disabled region and the first coordinates becomes shorter.

3. The input device according to claim 1,

wherein the coordinate processing unit corrects the first coordinates input to the correction region formed on a side of the end portion of the touch panel in a first direction to the second coordinates in the input disabled region formed on the end portion in the first direction or the correction region formed on the side of the end portion in the first direction.

4. The input device according to claim 1, further comprising a gripping determination unit which determines whether the input device is gripped,

wherein the coordinate processing unit forms the input disabled region and the correction unit when the gripping determination unit determines that the input device is gripped.

5. The input device according to claim 4,

wherein the coordinate processing unit forms the input disabled region and the correction region when the coordinate of the input to the touch panel in a direction perpendicular to a surface of the touch panel corresponds to coordinates in a predetermined range of non-contact with the touch panel.

6. The input device according to claim 1, further comprising an input means determination unit which determines whether input means for performing the input to the touch panel is a stylus pen,

wherein the coordinate processing unit forms the input disabled region and the correction region when the input means determination unit determines that the input means is the stylus pen.

7. The input device according to claim 1,

wherein the coordinate processing unit performs a disabling processing to disable third coordinates input to the input disabled region and also performs the correction processing.

8. An information terminal comprising the input device according to claim 1.

9. An input control method comprising:

detecting coordinates of input to a touch panel; and

performing a correction processing for detected input coordinates,

wherein, in the correction processing, first coordinates input to a correction region formed on an inner side of an end portion of the touch panel are corrected to second coordinates in an input disabled region formed within the end portion of the touch panel or in the correction region, based on a distance between the input disabled region and the first coordinates.

10. A non-transitory computer-readable medium storing an input control program comprising instructions, which when executed by a computer to execute each step of the input control method according to claim 9.
