DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handwriting stroke editing apparatus for editing handwriting information inputted by a tablet device as stroke information.

[0002]

2. Description of the Related Art In recent years, a system for inputting and processing handwriting information into a computer using a tablet device has appeared. As one of such systems, a system that handles handwriting information as stroke data, which is a set of point sequence data, has attracted attention. For example, the system is described in IPSJ Transactions, 1991, Vol. 32 No. 8 There is one reported by Moriya et al. In "Stroke editor and direct instruction / operation method". In this system, a pen-type input device is used to write a sentence on a screen with a ruled line, and perform editing processing in units of characters and lines as in a word processor.

In this type of system, stroke data must be accurately grouped in units of characters or lines in order to edit in units of characters or lines. This is to ensure the editing intended by the user. For example, when a line written in horizontal writing is changed to a line written in vertical writing, it can be realized by changing the position of the character if it is grouped correctly in character units and line units .

The method of grouping stroke data into character groups and line groups is described in IEICE Transactions '90 / 10 Vol.J73-D-II No.10 "Cut out characters from handwriting data" , IEICE Transactions' 9
0/7 Vol.J73-D-II No.7 It is described in "Cut out lines from handwriting data".

[0005]

However, in the above-mentioned prior art, it is impossible to perform grouping on a character unit or a line unit without completely error. Therefore, a character unit such as "delete" is added to the grouped result. However, there is a problem in that when editing is performed, stroke data different from the user's intention may be edited. For example, it is assumed that a character group that is one character cut out by the handwriting stroke editing apparatus is mistakenly grouped as “Ai”, which is different from the actual one character. In this case, if the user attempts to delete only "A" and performs an operation such as "Delete" while specifying this character group, "Ai" will be deleted.

[0006] On the other hand, in order to try grouping by character unit or line unit completely without error, a mesh is provided on the input screen, and when a handwritten character is input on the mesh, a group having no error is obtained. Can be performed. However, it is not possible to deal with characters of any size and the like, and the freedom of writing characters by hand like a memo is impaired.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a handwriting stroke editing apparatus which allows a user to edit a character unit without being conscious of a group of characters.

[0008]

In order to achieve the above object, according to the present invention, a handwritten stroke editing device stores strokes detected as one character as a character group,
Group management means for managing, display means for displaying strokes divided into managed character units, reception means for receiving an input of a range to be selected as an edit target, and storage in the group management means by the selection range Editing object selection means for detecting which character group is selected among all the character groups, and determining whether the entire character group is selected or a part thereof is selected. In each character group for which a copy is determined to be selected, when there are a plurality of character reconstructing means for reorganizing strokes belonging to the selected range as a new character group, and a plurality of character groups reconstructed by the character reconstructing means An integration availability determination means for determining whether to integrate these into one character group and an integration availability determination means are integrated. An integration unit that integrates two or more reconstructed character groups determined to be necessary into one character group, and a character group determined to be selected as a whole by the edit target selection unit. If editing is performed in units and it is determined that a part of the character group is selected by the editing target selecting means, and if the character group is integrated into one character group by the integrating means, the character group is In addition, there is provided a group unit editing means for performing editing in units and editing in units of the reconstructed character groups when none is integrated into a character group by the integrating means. here
The group management unit further stores a character group box that is a rectangle circumscribing the character group in association with the character group, and the editing target selection unit determines that an area where the selection range and the character group box overlap with each other is:
If the ratio exceeds the specified ratio for the character group box, it is determined that the entire character group has been selected. If the ratio is less than the predetermined ratio and overlaps, it is determined that a part has been selected. It is characterized by doing.

Further , the character reconstructing means generates a stroke box which is a rectangle circumscribing each stroke belonging to the character group, and an area where the selection range and the stroke box overlap each other has a predetermined ratio with respect to the area of the stroke box. A feature is provided that includes a determination unit that determines that the stroke belongs to the selection range when the stroke exceeds the selection range. Further, the group management means further stores, as a row group, a group of character groups forming a line, and the integration availability determination means determines whether the integrated character group is in the same line group. A determination unit that determines whether the character group is not too large compared to other character groups; and an integration availability determination unit that determines that integration should be performed only when the character group is not too large. I do.

Further, the group management means further stores a line group that are grouped with respect to the character group of people chunks constituting the row, handwriting strokes editing apparatus further the character reconstructing means and said integration means Is compared with the size of another character group not selected in the same line group, and if the result of the comparison indicates that the other character group is too large as one character group,
An in-line stroke re-dividing unit is provided, which performs an in-line stroke re-dividing unit for checking strokes in the line group based on the size of the reconstructed character group.

[0011]

According to the above arrangement, the strokes divided in character units, which have been cut off as one character and managed by the group management means, are displayed by the display means. The selection range is received from the user by a receiving unit.
According to the selection range, which character group of all the character groups stored in the group management means is selected is detected by the edit target selection means, and further, whether or not the entire character group is selected is partially determined. It is also determined by the editing object selecting means whether or not it has been selected. In each character group in which it is determined that a part of the character group is selected, the strokes belonging to the selected range are reconstructed as a new character group by the character reconstructing means. When there are a plurality of character groups reconstructed by the character reconstructing means, whether or not these should be integrated into one character group is determined by the integration possibility determining means. The two or more reconstructed character groups determined to be integrated by the integration possibility determination unit are integrated by the integration unit into one character group. For a character group determined to be entirely selected by the edit target selection unit, the group unit edit unit performs editing in the character group unit, and a part of the character group is selected by the edit target selection unit. If it is determined that the character group has been merged into one character group by the integrating means, the group unit editing means edits the character group unit,
When the character group is not integrated into one character group by the integrating means, the group unit editing means edits the reconstructed character group.

[0012] Here, the character group box is a rectangle circumscribing the character group is stored by the group management means in association with the character group. When the overlapping area of the selection range and the character group box exceeds a predetermined ratio with respect to the character group box, it is determined by the editing and selecting means that the entire character group is selected, and the predetermined ratio is determined. If there is an overlap in the following, it is determined by the editing and selecting means that a part is selected.

Here, a stroke box which is a rectangle circumscribing each stroke belonging to the character group is generated by the determination unit, and the area where the selection range and the stroke box overlap each other exceeds a predetermined ratio with respect to the area of the stroke box. Is determined to be a stroke belonging to the selection range by the determination unit. Here, a group of character groups forming a line is stored as a line group by the group management unit. The determination unit determines whether the character group obtained by integrating the plurality of character groups reconstructed by the character reconstruction unit is not too large as compared with other character groups in the same line group. . Only when the size is not too large, the integration availability determination unit determines that integration should be performed.

Here, a group of character groups constituting a line is further stored as a line group by the group management means. The size of the character reconstructed by the character reconstructing means and the integrating means is compared with another character group not selected in the same line group by the in-line stroke redividing means. If the group is too large as a single character group, the strokes in the line group are censored by the in-line stroke subdivision unit based on the size of the reconstructed characters.

[0015]

FIG. 1 is a diagram showing a configuration of a handwriting stroke editing apparatus according to this embodiment. As shown in the figure, the handwriting stroke editing device includes a tablet device 1, a group division device 2, a group management device 3, a gesture recognition device 4, an editing range instruction device 5, an editing target selection device 6, and a selected character group reconstruction. It comprises a device 7, an in-line stroke re-dividing device 8, a group unit editing device 9, and a display device 10.

The tablet device 1 receives handwritten data and an editing operation instruction from an operator via a dedicated pen. Here, the handwritten data is a handwritten character to be input, and the editing operation instruction is a handwritten instruction indicating an editing operation such as “delete”. In order to enable the above two types of reception, the mode can be switched between a handwritten data input mode for inputting handwritten data and an editing operation instruction mode. In the handwriting input data mode, the handwriting data is received and is sent to the group dividing device 2 as point sequence data including coordinate information indicating coordinate points while the pen is touching the tablet and time information indicating the input order. Output. On the other hand, in the editing operation mode, an editing operation instruction is received and output to the gesture recognition device 4 as point sequence data as in the handwriting input data mode. Switching between these two modes is realized by a side switch or other switch means provided on the pen.

The group dividing device 2 includes a tablet device 1
, And temporarily stores, as stroke information, point sequence data for each stroke unit corresponding to one-stroke operation. Then, when the input mode changes or when the user gives an instruction, the information managed as the stroke information is grouped into units of characters and units of lines. The group referred to here is a character group when a group of strokes constituting a character is grouped, and a line group when a group of character groups constituting a line is grouped. Further, the group dividing device 2 obtains the smallest rectangle including the strokes constituting the character group as a character group box. In addition, the smallest rectangle including the character group constituting the line group is obtained as a line group box. These character group box and line group box are called boxes. Information indicating these groups and boxes is called group information. Further, the group division device 2 passes the stroke information and the group information to the group management device 3.

The group management device 3 stores and manages character group information relating to each line group in association with a line group box which is a rectangle circumscribing the line group, based on the information passed from the group division device 2. In addition, stroke information relating to each character group is stored and managed in association with a character group box which is a rectangle circumscribing the character group. FIG. 5 shows an example of information stored and managed in the group management device 3. In the figure, thick solid line arrows represent links between management information, and can be traced in the direction of the arrows. A link is to combine pointers with related information. The broken arrow indicates that the link destination information is omitted. 501, 502 and 5
03 is row group information for managing the row group. 5
04, 505 and 506 are character group information for managing character groups belonging to the line group 501. 50
7, 508 and 509 are stroke information for managing strokes belonging to the character group 504. 510,5
Numerals 11 and 512 manage coordinate information of a sequence of points constituting the strokes 507, 508 and 509, respectively. Here, the line box information and the character box information are information of the line group box and the character box. In addition, the line modification information and the character modification information indicate line and character modification information. Specifically, there are shading and inversion.

In order to facilitate stroke editing, the stroke information of 507, 508 and 509 includes
It is also possible to include stroke box information. Also, from the character group information of 504, 505, and 506,
To access the line group information to which they belong,
It is also possible to have a link from character group information to line group information.

The gesture recognition device 4 receives coordinate information and point sequence data from the tablet device 1 in the editing operation instruction mode, and performs any type of editing by pattern matching the data with the previously registered point sequence data. Recognize the command data indicating whether the operation has been instructed, and send the command data to the group unit editing device 9.
Pass to. As an example, when the point sequence data as indicated by reference numeral 603 in FIG. 6 is received, this means "delete", and therefore, it is recognized as an edit operation of "delete".

When the editing operation recognized by the gesture recognizing device 4 requires an editing target, the editing range indicating device 5 determines an editing range from the range of the gesture written on the tablet, and sends it to the editing target selecting device 6. Specify the range as edit range information. Specifically, 603 in FIG.
The editing range indicated by reference numeral 604 in FIG. 6 is determined from the gesture written as shown in FIG.

The editing object selecting device 6 receives the editing range information designated by the user from the editing range instructing device 5 in the editing operation instructing mode, and uses this editing range information for each character managed by the group management device 3. , To determine which part of the row group is selected. It also has a character selection buffer and a line selection buffer for storing characters and line groups. If it is determined that the entire character or line group has been selected, the selected character or line group is stored in the character selection buffer and the line selection buffer. If it is determined that the entire character group has not been selected and only a part of the character group has been selected, it means that the actual one character is different from the one character cut out by the handwriting stroke editing device. In this case, the character group reconstructing device 7 is instructed to reconstruct the character group, and the reconstructed character group is stored in the character selection buffer.

Specifically, this is shown in the flowchart of FIG. In the figure, the first row group is extracted from the row group group managed by the group management device 3 and set in the inspection row group indicating the row to be inspected (step S20).
1). Here, the inspection target means that the editing target selection device 6
It refers to the line, character, stroke, etc., of interest at that moment. Next, the area of the area where the editing range passed from the editing range indicating device 5 and the inspection line group box which is a box of the inspection line group is calculated, and a value obtained by dividing the value by the area of the inspection line group box is calculated. OVERLAY_
Set to RATIO (step S202). For example, assuming that the inspection row group box is a range indicated by 606 in FIG. 6B and the editing range is a range indicated by 604 in FIG. 6B, an area where the editing range 604 and the inspection row group box 606 overlap is displayed. Is calculated, and the value obtained by dividing the value by the area of the inspection row group box 606 is OVE.
RLAY_RATIO. Next, the OVERLA
If the value of Y_RATIO is 0.7 or more, it is determined that the entire inspection row group has been selected, and the process proceeds to step S204. If the value is 0 or more and 0.7 or less, that is, it is determined that a part of the inspection group box overlaps with the editing range, and the process proceeds to step S208. If the value is 0, it is determined that they do not overlap, and the process proceeds to step S205 (step S203, step S207). Step S204
Then, the current inspection row group is set in the row selection buffer (step S204). Next, it is checked whether or not the group management device 3 manages a row group next to the current inspection row group. If the next row group exists, step S20
The process proceeds to step S6, and if not, the editing object selection device 6 is terminated and control is passed to the group unit editing device 9 (step S2)
05). In step S206, the next row group is set in the inspection row group, and the process returns to step S202 (step S206). This loop is repeated until all the row groups managed by the group management device 3 are checked.

On the other hand, in step S208, the first character group in the inspection line group is extracted and set in the inspection character group indicating the character to be inspected (step S20).
8). Next, the area of the area where the edit range passed from the edit range indicating device 5 and the check character group box, which is the box of the check character group, is calculated, and the value obtained by dividing the value by the area of the check character group box is calculated. OVER
Set to LAY_RATIO (step S20)
9). For example, if the check character group box is
FIG. 6B shows a range indicated by reference numeral 601 and the editing range is as shown in FIG.
If the range is indicated by 604 in (b), the area of the area where the edit range 601 and the check character group box 604 overlap is calculated, and the value is calculated as the check character group box 6.
The value divided by the area of 06 is OVERLAY_RATIO. Next, the value of the OVERLAY_RATIO is checked. If the value is 0.8 or more, it is determined that the entire check character group has been selected, and the process proceeds to step S211.
If LAY_RATIO is larger than 0, that is, if the edit range and the check character group box overlap even in a part, control is passed to the selected character group reconstructing device 7 and O
If VERLAY_RATIO is 0, that is, if they do not overlap, the process proceeds to step S212 (step S21).
0, step S214). In step S211, the current check character group is set in the character selection buffer (step S211). Next, it is checked whether the group management device 3 manages a character group next to the current check character group. If the next character group exists, step S2 is performed.
The process proceeds to step S215 if it does not exist (step S212). In step S213, the next character group is set in the check character group, and step S213 is executed.
The process returns to 209 (step S213).

This loop is repeated until all the character groups in the current inspection line group have been inspected. In step S215, it is determined whether a reconstructed character group exists. The reconstructed character group is a character group that has been set as the reconstructed character group 1 by the processing of the selected character group reconstruction device 7. Details will be described in step S309 of FIG. If there is no reconstructed character group, the process proceeds to step S205 (step S21).
5). Here, if there are a plurality of reconstructed character groups and there is a need to integrate the reconstructed characters into one character group, the process proceeds to step S218. For example, FIG.
As shown by 607 and 608 in (b), when there are two such reconstructed character groups, it is determined that it is necessary to integrate them into one character group such as 605 in FIG. 6C. Next, if there is no need to integrate even if there is one or more reconstructed character groups, step S21
Proceed to 7. Here, whether to combine the reconstructed character groups is determined based on information such as the distance between the reconstructed character groups and the size of the integrated character group (step S216). In step S217, the reconstructed character group is put into the character selection buffer. Thereafter, the in-line stroke subdivision device 8 is activated (step S217). In step S218, the reconstructed character groups are integrated into one character group, and then put into a character selection buffer. Thereafter, the in-line stroke subdivision device 8 is activated (step S218).

In step S203, a value of 0.7 is used to determine whether an inspection row group has been selected. However, this value can be arbitrarily changed. It may be dynamically changed based on data to be performed. 0.8 in step S210
Is the same. Upon selection, the character group reconstructing device 7 receives an instruction for reconstructing a character group from the editing target selecting device 6 and determines, for all strokes belonging to the character group, those included in the selected range and those not included in the selected range. Separately select and form a character group with each. The composed character group is managed by the group management device 3.
It also has a reconstructed character group buffer for storing the character groups selected and sorted.

The specific control contents are shown in the flowchart of FIG. First, the first stroke of the stroke group constituting the character group under inspection is extracted by the editing object selection device 6, and is set as the inspection stroke indicating the inspection object (step S301). For example, in the editing target selection device 6,
Assuming that the character group indicated by 601 in FIG. 6B is under inspection, 601 a in the figure is extracted as the first stroke in the character group 601. Next, a group of coordinate information constituting the inspection stroke is sequentially extracted from the group management device 3, and a stroke box circumscribing the inspection stroke is created (step S302). The area of the region where the edit range passed from the edit range indicating device 5 and the stroke box overlaps is calculated, and the value obtained by dividing the value by the area of the stroke box is calculated as OVERLAY_RATI.
It is set to O (step S302). OVERLAY
The value of _RATIO is checked, and if it is larger than 0.9, it is determined that the inspection stroke is selected, and step S305 is performed.
If it is 0.9 or less, it is determined that no selection has been made, and the process proceeds to step S306 (step S304). For example, if the head stroke is 601a in FIG. 6B, the stroke does not overlap the edit range 604 at all, and in this case, the process proceeds to step S306. Step S30
In step 5, the current inspection stroke determined to be selected in step S304 is linked to the reconstructed character group 1 to form a new character group (step S305).
Thereafter, the process proceeds to step S307. In step S306, the current inspection stroke determined not to be selected in step S304 is linked to the reconstructed character group 2 (step S306). The processing in steps S302 to S306 is performed for all strokes in the character group 601 (steps S307 and S308). As a result, since only the inspection stroke 607 is included in the editing range 604, the reconstructed character group 1 is linked, and the remaining strokes 601a to 601c are linked to the reconstructed character group 2 (step S30).
5, step S306).

In step S309, the reconstructed character group 1 is set in the reconstructed character group buffer. Reconstructed character group 1 composed of selected stroke groups
To the group management device 3 to manage the reconstructed character group 2 composed of the stroke groups not selected as character groups, and passes control to step S212 of the edit target selection device 6 (step S31).
0).

Although the stroke box circumscribing the inspection stroke is created in step S302, the stroke box can be created in the group division device 2 in the data input mode and managed by the group management device 3. In that case, step S30
Operation 2 can be modified to retrieve the stroke box from the group management device. Step S30
In 4, the value of the area ratio for determining whether the inspection stroke is selected is set to 0.9,
This value can be arbitrarily changed, and may be dynamically changed based on data managed by the group management device 3.

The in-line stroke re-dividing device 8 determines whether or not to perform a split reconstruction on another character group not selected in the line group to which the reconstructed character group belongs, and performs the split reconstruction. In this case, all the strokes belonging to the line group are re-divided into a new character group except for those belonging to the currently selected character group.

More specifically, this is shown in the flowchart of FIG. First, the sizes of the boxes of all the character groups constituting the inspection line group are averaged, and the value is set in the average character box (step S401). A box of the reconstructed character group notified from the editing object selecting device 6 is obtained, the size of the box is compared with the size of the average character group, and another character group is determined by one character according to the comparison result.
If the group is too large, it is determined that the stroke in the inspection line group needs to be re-divided into a new character group, and the process proceeds to step S403. Otherwise, the subdivision of the strokes in the inspection row group ends, and control is passed to step S205 of the editing target selection device 6 (step S402).

A square whose one side is the larger value of the height or width of the reconstructed character group box is created as a character box for in-line reconstruction, and is used as a reference for re-dividing the stroke group (step S403). . All the strokes in the inspection line group are divided into a new character group using the information of the created in-line reconstruction character box. However, the strokes constituting the character group already selected by the editing target selecting device 6 are not re-divided (step S404). Next, the group management apparatus 3 is notified to update the row group management information after the subdivision of the stroke in the inspection row (step S405).

In the method of comparing the size of the reconstructed character box and the size of the average character box in step S402, the height and width of each box may be compared, and the area may be compared. . Further, the threshold value of the criteria to subdivide the inspection row strokes can be arbitrarily set, the data managed by the group management apparatus 3 may be dynamically changed based.

The group-based editing device 9 receives the editing operation recognized by the gesture recognition device 4 and performs a group-based editing operation on a character group and a line group stored in the character selection buffer and the line selection buffer. . The display device 10 displays stroke information divided into character units managed by the group management device 3.

The characteristic operation of the handwritten stroke editing apparatus configured as described above will be described with reference to the drawings. First, FIG. 6 will be described. FIG. 6A shows a part of the character group group in the line group 606. This example shows that each stroke is divided into two character groups 601 and 602 unlike the user's intention. In other words, although the actual characters are “A”, “I”, and “U”, the handwritten stroke editing apparatus erroneously classifies 601 and 602 as one character. FIG.
(B) shows a state in which the user has issued an editing instruction in order to delete a stroke group representing "I" in the editing operation instruction mode. Reference numeral 604 denotes an editing range. Since the character group 601 partially overlaps the editing range, the selected character group reconstructing device 7 reconstructs the character group. As a result, the stroke 607 constituting the left half of “i” overlapping the editing range is stored as a reconstructed character group in the reconstructed character group buffer. The same applies to the character group 602, and the stroke 608 constituting the right half of "i" is stored as a reconstructed character group in the reconstructed character group buffer. Then, the editing target selecting device 6 sets
And 608, the reconstructed character groups are integrated and reconstructed as a new character group. As shown in FIG.
This will result in correct character group division. Thereafter, the character group indicated by 605 is deleted by the group unit editing device 9.

Next, FIG. 7 will be described. In FIG. 7A, unlike the user's intention, the actual characters are “A” and “I”.
This indicates that the handwritten stroke editing apparatus cuts out "Ai" as one character and "U" as one character even though the characters are "U" and "E". At this time, as shown in FIG. 7B, when an editing instruction operation indicating deletion is performed on a stroke group representing “U”, which is a part of the character group 702, the character group 702 is provided as in the example of FIG. Is divided into two character groups 705 and 706, and the character group 70
5 is selected for editing. Thereafter, the in-line stroke re-dividing device 8 creates a square having one of the larger sides of the height and width of the character group 705 as a character box for in-line reconstruction, and re-divides the in-line stroke based on this. . The result of the subdivision is shown in FIG. After that, the selected character group 705 is deleted by the group unit editing device 9 as in the example of FIG.

According to the present invention as described above, claim 1
In the case where there is a mismatch between the selection range designated by the user and the range of the character group managed by the group management means, the stroke data belonging to the character group and the selection range is newly reconstructed by the character reconstruction means. The character group is reconstructed as a constituent character group, and when the reconstructed character groups are to be integrated by the integration means, they are integrated into one character group. Therefore, the user is aware of the group of characters managed by the group management means. Editing can be performed in units of characters intended by the user without the need.

According to a second aspect, when the area where the selection range and the character group box overlap exceeds a predetermined ratio with respect to the area of the character group box, it is determined that the entire group is selected, and In the case where there is an overlap below a certain ratio, and even if there is any overlap, the character reconstructing means is provided with an editing object selecting means for instructing the restructuring of the group, so that it is possible to quickly determine whether or not to reconstruct the character group Can be performed.

According to a third aspect of the present invention, a stroke box which is a rectangle circumscribing each stroke belonging to the character group is generated, and the stroke area where the selection range and the stroke box overlap each other exceeds a predetermined ratio with respect to the area of the stroke box. Is determined to be a stroke belonging to the selection range, so that the selected stroke can be discriminated at high speed.

According to the fourth aspect, the judging section judges whether or not the character group in the case of merging is too large as compared with other characters in the same line group. Since the integration possibility determination unit determines that it should be performed, it is possible to prevent a stroke group having an area significantly larger than other characters from being erroneously recognized as one character.

According to a fifth aspect of the present invention, using the information on the size of the character group newly reconstructed by the character reconstructing means, it is determined whether another character group not selected in the same line is not too large. If the result shows that it is appropriate to perform split reconstruction on other character groups, the strokes in the line group are regrouped into character groups. The accuracy of grouping of other characters in the group can be improved.
