1. A computer-based character input apparatus, comprising:
- input means for inputting characters by using an input unit;
region recognition means for recognizing a region on an input surface of the input unit in which the characters have been input; and
character recognition means for, in a first, title-entry mode, recognizing the input characters in the region recognized by said region recognition means and for assigning a title to the region based on the recognized input characters, and for, in a second, data-entry mode, recognizing further characters input in the region to which the title has been assigned, the further characters recognized based on a limited set of expected characters related to the title.

Abstract
The present invention relates to a character input apparatus and method which pairs the title of a heading to the region where a character is inputted and determines the character group which can be inputted into the region corresponding to the heading as input candidate characters. When a character is inputted in the region, the heading in that region is discriminated and the characters are recognized referring to the input candidate character group corresponding to the title of the heading.

9. A computer-based character input method for recognizing an input character and obtaining a character code corresponding to the input character, the method comprising:
-
an input step of inputting characters by using an input unit; a recognition step of recognizing the characters input on the input surface; and a region recognition step of recognizing a region of the input surface in which the characters are input, wherein, in a first, title-entry mode, characters input in said input step are recognized and a title is assigned to the region based on the recognized characters, in said recognition step, and wherein, in a second, data-entry mode, further characters input in the region to which the title is assigned are recognized in said recognition step based on a limited set of expected characters related to the title. - View Dependent Claims (10, 11, 12, 13)
