Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus having a function of recognizing handwritten information.

[0002]

2. Description of the Related Art A conventional keyboard and mouse are mainly used as inputs for a conventional document processing apparatus, but these operations are unnatural to human senses and it takes a lot of effort to get used to them. There is. Therefore, a pen-type interface for designating a position with a pen and writing and inputting characters by a character recognition function on a tablet in which display and input are integrated has attracted attention.

In this type of character input, a character is written in a specific area (character writing frame) and the recognition result (character) is input at the cursor position, and a character is written at an arbitrary position.
Although there is one that inputs characters at the writing position, it is more human-like to input characters at the writing position and is superior in operability. However, the method of inputting characters at the writing position is effective when there is no format such as memo writing, but when inputting on the screen where the line and column of the character are set, the positional relationship with the already input character There is a problem that inconvenience arises from the above.

Therefore, the same applicant filed Japanese Patent Application No. 3-3319.
Japanese Patent Laid-Open No. 37/37, filed for determining the output position of an input character from the positional relationship with the character and the linguistic relationship when an already-input character exists in a specific area including the input character. In the present invention, in order to further solve the above problem, based on the writing position, when there is no already input character in the same line as the writing position, the position left-aligned in the line is set as the output position, and the writing position If there is an already-input character in the same line and the writing position is within the specific character from the right end of the already-input character, the output position is the position at the right end of the already-input character.

Further, at least two determining means for determining the output position as described above are provided, and based on the writing position,
The output position is determined by a specific determining means of the determining means.

[0006]

FIG. 3 is a diagram showing the relationship between the writing position of input characters and the output of the embodiment of the document processing apparatus of the present invention. In the figure (a), the already input characters "basic" 31 and "basic research" 3
2. In the character output area in which "basic" 33 and "basic" 34 are input, handwritten "basic" 35, "study" 36,
It is the figure which showed the state when "application" 37, "research" 38, and "research" 39 were written. In the figure, the already input characters 31, 32, 33, 34 and the handwritten input character 35,
36, 37, 38, and 39 are shown by changing the size of characters for the purpose of explanation.

FIG. 3B shows the recognition results of FIG. 3A, which are 35 and 40, 31 and 36 and 41, 32 and 37 and 42, 33 and 38 and 43, 34 and 39 and 44.
Correspond to each. FIG. 2 is a flow chart showing an output position determining method of the character output position determining device 6 shown in FIG. 1 of one embodiment of the document processing device of the present invention.

The flow of processing shown in FIG. 3 will be described with reference to FIG. First, in STEP 1, it is determined whether or not there is an already input character. If there is no already input character in the same line as the written character position, 0 is input in the output position in STEP 9.
That is, 35 in FIG. 3A is output to the position left justified in the row, as indicated by 40 in FIG. 3B. On the other hand, if there is an input character on the same line as the written character position, S
At TEP2, the output candidate position x is obtained from the writing position.

Next, in STEP 3, it is determined whether or not the output candidate position x obtained in STEP 2 is larger than the number of already input characters and smaller than the number of already input characters + N (N: 0 to 2).
If it is determined that the above conditions are met, STEP
At 8, the number of characters already input is input to the output position. That is, FIG.
36 of (a) is output to the position following the already input character 31, as shown by 41 of FIG. On the other hand, when the output candidate position x is not included in this range, it is determined in STEP 4 whether the output candidate position x is less than or equal to the number of already input characters.

Next, if it is determined from the determination result that the output candidate position x is less than or equal to the number of already input characters, STEP
At 7, the output candidate position x is input as the output position. That is, FIG.
37 of (a), as shown by 42 of (b) of the figure, an output obtained by rewriting a part of the already input character 32 is obtained. On the other hand, when it is determined that the output candidate position x is larger than the number of already input characters, it is determined in the next STEP 5 whether or not the mode is one in which one character is left blank.

If it is determined from the next determination result that the mode is not one blank space, the output candidate position x is input to the output position in STEP 7. That is, FIG. 3 (a)
38 indicates that the input character 3 has already been input, as indicated by 43 in FIG.
It is output at the writing position regardless of 3. On the other hand, if it is determined that the mode is one character blank, STEP6
Input the number of input characters + 1 at the output position. That is, 39 in FIG. 3A is input from a position one character after the already input character 34, as indicated by 44 in FIG. 3B (the blank is represented by 43 in the same figure). ..

The mode for leaving a space for one character may be set by the user with an icon or the like or may be initially set according to the purpose. Further, in the present embodiment, the processing as shown in FIG. 2 is performed as the determining means for determining the output position, but the present invention is not limited to this embodiment, and there is a character at the output candidate position x, for example. It is determined whether or not there is an output candidate position as the output position, and if there is no character to the left of it, it is determined as the output position.
On the other hand, if there is no character at the position adjacent to the left, it is determined whether or not there is a character further next to it. By the judgment, left 2
If there is no character next to it, the output candidate position is the output position,
If there is, it can be realized by setting the position obtained by subtracting 1 from the output candidate position as the output position.

In this embodiment, characters are managed in units of lines. That is, each line is continuous like the display screen of the conventional document processing apparatus, and characters overflowing on one line are input to the next line. However, each line can be considered as an independent entry frame, such as schedule management. Even in that case, the present invention is effective. Also, by thinking in the same way as when each line is independent, it can be applied to the case where there is only one line such as when the writing frame is provided separately from the display screen.

Further, in the present embodiment, the above five are shown as the deciding means for deciding the output position, but insertion or the like is also conceivable.

[0024]

According to the present invention, an appropriate output position can be determined based on a writing position of an input character even when inputting on a screen in which a line and a column of the character are set. The time and effort required to move to a desired position after input is greatly reduced. Further, since an appropriate output position is set based on the writing position, the labor of inputting while paying attention to the writing position as in the conventional case is greatly improved, and an easy-to-use handwritten document processing device can be realized.
