Abstract

A handwriting input apparatus and a computer readable recording medium recorded with an image processing program are provided, which both enable easy edit and high-quality display of edited content. A defining module defines a locus of a character and/or graphic contained in a group. When a gesture indicative of an edit command is inputted by a handwriting input module, then an edit management module interprets the inputted command and executes it. At this time, the execution of the command accompanies movement of the character and graphic in the group, and this movement follows the defined locus.

Claims

1. An input apparatus comprising:

a handwritten character and/or graphic input device for inputting a character and/or graphic written by hand;

a storage unit for storing handwritten data constituted of handwritten characters and/or graphics inputted by the handwritten character and/or graphic input device;

a handwritten edit command input device for inputting a command of editing the handwritten data by hand;

an input direction detecting unit for detecting an input direction of handwriting a group consisting of a set of characters and/or graphics contained in the handwritten data;

an edit management unit for detecting a command when the command is inputted by the handwritten edit command input device, and controlling the characters and/or graphics in the group so as to move in the input direction during execution of the command; and

a display unit for displaying the handwritten data, handwritten data which has not yet been edited by the edit management unit, and handwritten data which has been edited after the execution of the edit command.

2. The input apparatus of claim 1, wherein the input direction detecting unit detects a rectangle circumscribing each of characters and/or graphics contained in the group and detects a geometric center of the detected circumscribing rectangle to determine a locus connecting all points of the detected geometric center.

3. The input apparatus of claim 2, wherein the edit command includes a deletion command, and

when the deletion command is inputted as a handwritten edit command, the edit management unit deletes a character and/or graphic to be deleted and causes a character and/or graphic located after the deleted character and/or graphic in the input direction to move forward in the input direction so as to follow the locus.

4. The input apparatus of claim 2, wherein the edit command includes a correction command, and

when the correction command is inputted as a handwritten edit command, the edit management unit deletes a character and/or graphic to be corrected;

when a character and/or graphic to be corrected is inputted by the handwritten character and/or graphic input device, detects a rectangle circumscribing the inputted character and/or graphic and a graphic center of the circumscribing rectangle; and

places the inputted character and/or graphic to be corrected so as to have the detected graphic center positioned on the locus.

5. The input apparatus of claim 2, wherein the edit command includes an insert command, and

when the insert command is inputted as a handwritten edit command, the edit management unit moves along the locus a character located before or after an insert position in the input direction so as to make a predetermined space in between a character and/or graphic located after the insert position in the input direction and a character and/or graphic located before the insert position in the input direction;

detects a rectangle circumscribing a character and/or graphic to be inserted which is inputted by the handwritten character and/or graphic input device, and a geometric center of the rectangle; and

places the inputted character and/or graphic to be inserted so as to have the detected geometric center positioned on the locus in the space.

6. A computer readable recording medium recorded with an image processing program for operating a computer as the input apparatus of claim 1.
