Abstract

A handwritten-information processing apparatus includes a handwritten-information acquisition unit and a handwritten-information insertion unit. The handwritten-information acquisition unit acquires a handwritten information item which has been handwritten by a user on a medium having a region inside a writing frame and a region outside the writing frame. The region inside the writing frame includes division regions. The region outside the writing frame is located outside the region inside the writing frame. When the handwritten-information acquisition unit has acquired an insertion mark which is a handwritten information item extending across a boundary between the region inside the writing frame and the region outside the writing frame, the handwritten-information insertion unit inserts, on the basis of the insertion mark, into the region inside the writing frame, a handwritten information item which has been handwritten in the region outside the writing frame.

in a case where the handwritten information item is located in one of the plurality of division regions, classifies the handwritten information item as a character inside the writing frame,

in a case where the handwritten information item is located in the region outside the writing frame, classifies the handwritten information item as a character outside the writing frame, and

in a case where one of two endpoints of a stroke making up the handwritten information item is located in the region inside the writing frame and where the other endpoint is located in the region outside the writing frame, classifies the handwritten information item as an insertion mark.

3. The handwritten-information processing apparatus according to claim 2, wherein

the handwritten-information classification unit,

in a case where the length of a stroke making up the handwritten information item is smaller than a predetermined length and where all points of the stroke are located in the region inside the writing frame, classifies the stroke as a stroke for use in a character inside the writing frame, the stroke for use in a character inside the writing frame being a stroke making up the character inside the writing frame, and

in a case where the length of a stroke making up the handwritten information item is smaller than the predetermined length and where all points of the stroke are located in the region outside the writing frame, classifies the stroke as a stroke for use in a character outside the writing frame, the stroke for use in a character outside the writing frame being a stroke making up the character outside the writing frame.

4. The handwritten-information processing apparatus according to claim 3, wherein

the handwritten-information classification unit,

in a case where a plurality of strokes for use in a character inside the writing frame are located in the same division region among the plurality of division regions, classifies a handwritten information item made up of the plurality of strokes for use in a character inside the writing frame, as one character inside the writing frame, and

in a case where the positions of a plurality of strokes for use in a character outside the writing frame are close to each other, classifies a handwritten information item made up of the plurality of strokes for use in a character outside the writing frame, as one character outside the writing frame.

5. The handwritten-information processing apparatus according to claim 2, wherein the handwritten-information insertion unit determines whether or not at least a character inside the writing frame, a character outside the writing frame, and an insertion mark are present, and, in a case where all of a character inside the writing frame, a character outside the writing frame, and an insertion mark are present, the handwritten-information insertion unit inserts, into the character inside the writing frame, the character outside the writing frame that is located in the vicinity of one endpoint which is one of two endpoints of a stroke making up the insertion mark and which is located in the region outside the writing frame.

6. The handwritten-information processing apparatus according to claim 3, wherein, in a case where two endpoints of a stroke making up the handwritten information item that has been handwritten by the user are located in the region outside the writing frame and where the length of the stroke making up the handwritten information item is smaller than a predetermined length, the handwritten-information classification unit further classifies the handwritten information item as a combining mark.

7. The handwritten-information processing apparatus according to claim 6, wherein

the handwritten-information classification unit,

in a case where the length of a stroke making up the handwritten information item is larger than the predetermined length, where one of two endpoints of the stroke is located in the region inside the writing frame, and where the other endpoint of the stroke is located in the region outside the writing frame, classifies the stroke as a stroke for use in an insertion mark, the stroke for use in an insertion mark being a stroke making up the insertion mark, and

in a case where the length of a stroke making up the handwritten information item is larger than the predetermined length and where all points of the stroke are located in the region outside the writing frame, classifies the stroke as a stroke for use in a combining mark, the stroke for use in a combining mark being a stroke making up the combining mark.

8. The handwritten-information processing apparatus according to claim 7, wherein the handwritten-information classification unit classifies one stroke for use in an insertion mark as one insertion mark, and classifies one stroke for use in a combining mark as one combining mark.

9. The handwritten-information processing apparatus according to claim 6, wherein, in a case where the position of each of a plurality of strokes for use in a character outside the writing frame is close to a combining mark, the handwritten-information classification unit classifies a handwritten information item made up of the plurality of strokes for use in a character outside the writing frame as one character outside the writing frame.
