Abstract
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. <IMAGE>

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
59 words
A character input apparatus which recognizes an inputted character and obtains a character code corresponding to the inputted character, comprising: discrimination means for discriminating the heading information corresponding to the position where the character was inputted; and recognition means for recognizing the inputted character referring to a stored candidate character group for character recognition corresponding to the heading information.
Claim 2
Dependent Claim
34 words
A character input apparatus according to claim 1, wherein said discrimination means discriminates the heading information on a ruled line corresponding to the position where the character was inputted as the corresponding heading information.
Claim 3
Dependent Claim
23 words
A character input apparatus according to claim 1, further comprising designation means for designating the candidate character group corresponding to the heading information.
Claim 4
Dependent Claim
120 words
A character input apparatus which recognized an inputted character and obtains a character code corresponding to the inputted character, comprising: discrimination means for discriminating to which region the inputted character belongs according to the position information which defines that region; storage means for storing specific information which specifies the region corresponding to the region; candidate character storage means for storing recognition candidate characters for character recognition corresponding to the specified information; and character recognition means for discriminating the input region by said discrimination means when the character was inputted and recognizing the inputted character referring to the recognition candidate characters which are stored in said candidate character storage means on the basis of the specified information corresponding to the region.
Claim 5
Dependent Claim
17 words
A character input apparatus according to claim 4, wherein said region is defined by ruled line information.
Claim 6
Dependent Claim
18 words
A character input apparatus according to claim 4, wherein said specified information is the title of a heading.
Claim 7
Dependent Claim
52 words
A character input apparatus according to claim 4, wherein said character recognition apparatus displays a plurality of candidate characters as a result of character recognition processing, in the case where the plurality of character candidates are present, and outputs the character which was selected among the candidate characters as the recognition result.
Claim 8
Dependent Claim
24 words
A character input apparatus according to claim 4, further comprising candidate character designation means for designating the candidate characters corresponding to the specified information.
Claim 9
Dependent Claim
180 words
A character input apparatus which recognizes an inputted character and obtains the character code corresponding to the inputted character, comprising: input means having a transparent coordinate input face for inputting the coordinate position information which is designated on the coordinate input face; display means having a display screen which is the same size as the coordinate input face and accommodating the display screen under the coordinate input face; ruled input means for inputting the ruled information which regulates the character input region on the display screen and displaying on said display means; heading title input means for inputting the title of a heading corresponding to the ruled line; discrimination means for discriminating the corresponding title of the heading when the character is inputted into the character input region defined by the ruled line; storage means for storing the recognition candidate characters corresponding to the title of the heading; and recognition means for recognizing the inputted character referring to the candidate characters which are stored in said storage means corresponding to the title of the heading discriminated by said discrimination means.
Claim 10
Dependent Claim
51 words
A character input method which recognizes an inputted character and obtains the corresponding character code, comprising the steps of: discriminating heading information corresponding to the position where the character was inputted; and recognizing the inputted character referring to a stored candidate character group for character recognition corresponding to the heading information.
Claim 11
Dependent Claim
34 words
A character input method according to claim 10, wherein said discrimination step discriminates the heading information on a ruled line corresponding to the position where the character was inputted as the corresponding heading information.
Claim 12
Dependent Claim
23 words
A character input method according to claim 10, further comprising designation step for designating the candidate character group corresponding to the heading information.
Claim 13
Dependent Claim
98 words
A character input method which recognizes an inputted character and obtains the character code corresponding to the inputted character, comprising the steps of: setting a region to specify an input region of a character input screen; providing the specified information corresponding to each set region; setting the recognition candidates of the character which is inputted to the region corresponding to the specified information; discriminating the input region where the character was inputted and determining the recognition candidates in the region according to the specified information of the region; and recognizing the inputted character referring to the recognition candidates.
Claim 14
Dependent Claim
58 words
Apparatus for inputting freehand characters, comprising means for displaying selected ones of a plurality of input fields, means for inputting an image signal corresponding to handwritten characters, and recognition means for recognizing said handwritten characters, characterised in that the recognition means is operable to recognize said characters in dependence upon the field with which said characters are associated.
Claim 15
Dependent Claim
24 words
A character input method and apparatus which selects characters for recognition according to the subjects of headings under which the characters are being input.
Claim 16
Dependent Claim
86 words
A handwriting input system comprising display means for displaying data fields, handwriting image signal input means for inputting an image signal corresponding to handwriting, at a specified portion of said display and recognition means for recognizing predetermined characters in said image signal, in which the recognition means operate in accordance with the field to which the handwriting is being input, and the display means is arranged to vary the positions of said fields, and the recognition means is arranged to take account of said positional variations.
Claim 17
Dependent Claim
11 words
A character input system including a variable format window mode display.
