摘要： PROBLEM TO BE SOLVED: To make it possible to guess which of full-size or half-size characters a writer tried to input. SOLUTION: A full-size half-size character recognition part 12 decides whether each of recognition candidate characters as the result of the recognizing process by a recognition part 12 for a handwritten character is a full-size half-size character or not. In the case of the full-size half-size character, the full-size half-size is retrieved as a reference character by a reference character retrieval part 16 toward the head character direction as to an input character string which is held in an input character string storage part 131 and is selected as a recognition result out of the recognition candidate characters for each handwritten character. When the reference character can be retrieved, a full-size/ half-size decision part 17 determines which of the full-size or half-size characters is preferential as to a recognition character string decided as the full-size half- size character according to which of the full-size or half-size characters of the retrieved reference character is.

摘要： PROBLEM TO BE SOLVED: To realize the operation changing a display in the expansive or reductive direction in real-time by user's simple input operation and to mitigate a limit in display magnification. SOLUTION: When the user performs the operation pushing a left or right button of a mouse 111 while pushing a shift key of a key board 112 in the state that the user operates the mouse 111, and moves a mouse cursor on a picture area of a display device 140 to a required reference position, whether a real-time display in the expansive or reductive direction is instructed is detected by an expansive/reductive direction detection device 121. An expansive/ reductive picture generation device 123 calculates a display subject frame and the display magnification based on a lapse time and the reference position in the period when the operation is performed, and reads in the display data within the display subject frame from a virtual picture storage 130, and expands or reduces them at the calculated display magnification, and executes repeatedly the operation displaying on the picture area.

摘要： PROBLEM TO BE SOLVED: To eliminate the need for repetitive calculation in matching without giving any influence to matched results without selecting any model character. SOLUTION: This character recognizing device is constituted in such a way that a feature point and segment extracting section 13 extracts feature points and segments through an input section 11 which inputs information from the outside and a line thinning section 12 and a labeling section 14 labels each segment with the ID of the field. Then a template generating section 15 generates templates at every field based on the labeled segments and stores the templates in a template storing section 151 and a stroke extracting section 16 labels each segment of an input character based on the information stored in the storing section 151 and extracts the segments having the same label as one stroke. In addition, a discriminating section 17 discriminates the extracted stroke for truth and falsehood based on the knowledge stored in a knowledge storing section 171 and an output section 18 outputs the information on the extracted stroke which is discriminated as 'truth'.

摘要： PROBLEM TO BE SOLVED: To easily and exactly perform the position designation of character components by preparing plural kinds of component templates matched with a character structure so as to selectively use them. SOLUTION: A picture is displayed while containing a component template display area 1001 and a component pattern input frame 1002 arranging plural kinds of component templates having different area dividing lines corresponding to the kind of the character structure and an input person designates area in one component template and inputs the stroke of the character component to the input frame 1002. The designated area in the component template is detected and turned into selected state, the coordinate sequence of the stroke inputted to the input frame 1002 is detected and inputted and based on the information on the coordinate sequence of that stroke and the detected area in the component template, component pattern recognizing processing is performed for recognizing the component of the relevant stroke. Then, a KANJI candidate, with which the recognized component can be arranged within the relevant area in the component template, is retrieved.

摘要： PROBLEM TO BE SOLVED: To shorten the time needed for pattern recognition and reduce the capacity of a dictionary, and further to perform stable feature extraction and stroke integration. SOLUTION: A line thinning processing for an input character pattern P is performed by a line thinning processing part 1, feature points and segments are extracted by a feature extraction part 2 according to the line-thinned image T, and a stroke integration part 3 obtains stroke information I on the basis of the feature point information and segment information S. A dictionary matching part 4 extracts a stable stroke from the stroke information I according to dictionary information D containing information on stable strokes which are registered in the dictionary 41 and have small influence of character deformation, matches it against the dictionary information D, and outputs the result R. In case of a failure in dictionary matching, a feature point correction part 22 corrects the feature point information C on a top-down basis according to the dictionary information D and a stroke correction part 32 corrects the stroke information, so that those corrected pieces of information will be used for rematching at the dictionary matching part 4.

摘要： PURPOSE: To attain more accurate pattern recognize by detecting the partial area of a character pattern, storing the detected area and acquiring a feedback rule for rerecognizing the character pattern when a recognized result obtained from an output part is not determinate, and when a succeeding recognized result is not determinate, executing rerecognition by using the feedback rule. CONSTITUTION: A character pattern or a picture pattern inputted to an input part 1 is learned and an unleaned character pattern or picture pattern is sorted by an intermediate part 2. The intermediate part 2 summarizes information to be outputted and an output part 3 outputs a final recognized result. When the outputted recognized result is not determinate, a feedback control part 41 in a feedback part 4 detects the partial area of the character pattern and stores the detected area in a feedback data base 42. A feedback rule corresponding to the partial area is acquired by storing the area, and when a succeeding recognized result is not determinate, rerecognition is executed by using the feedback rule. Thereby more accurate recognition can be attained.
