First Claim
1. A character input device connected to a touch panel, the character input device for setting a keyboard image and an input character display area on the touch panel, the keyboard image including a plurality of character keys each having a plurality of characters assigned thereto;
- when an initial touch on any one of the plurality of character keys on the keyboard image is detected, for selecting one character out of the plurality of characters assigned to the character key detected to have been touched in accordance with change in a touch position after detection of the initial touch; and
for displaying a selected character on the input character display area, the character input device comprising;
a computer programmed to act as;
a defining information storage unit that stores a defining information used to divide each of the plurality of character keys into a plurality of subregions located within the divided character key prior to detection of the initial touch;
a subregion discrimination unit for identifying a subregion including a touch detection point out of subregions set for the character key where the touch is detected, based on the defining information of the character key;
a discriminating region setting unit that sets a plurality of discriminating regions to a character key on which an initial touch is detected such that, both when an identified subregion comprises a central portion of the character key and when the identified subregion does not comprise the central portion of the character key, the discriminating regions are positioned around a center of the identified subregion that further comprises a detection point of the initial touch, the identified subregion is identified by the subregion discrimination unit, each of the plurality of discriminating regions corresponds to the plurality of characters assigned to the touched character key; and
an input character selection unit that selects, as the character displayed on the input character display area, a character that corresponds to a discriminating region, out of the plurality of discriminating regions set by the discriminating region setting unit, where a touch release was detected after detection of the initial touch.

Abstract
A character input device that sets a keyboard image and an input character display area on a touch panel, the keyboard image including a plurality of character keys and that receives operation on the keyboard image. The character input device identifies a subregion including a touch detection point from among subregions set based on the defining information relating a character key detected to be touched, and sets a plurality of discriminating regions so that the discriminating regions are distributed based on the identified subregion. Each of the plurality of discriminating regions corresponds to the plurality of characters assigned to the character key. When a touch release is detected, a character that corresponds to the discriminating region including the detection point of the touch release is selected as an input character. The character is then displayed on the input character display area of the touch panel.
