[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a handwriting input device according to an embodiment of the present invention. In FIG. 1, a handwriting input device 22 according to the present embodiment is an input unit and an input / output integrated type liquid crystal tablet 10 which is a display unit.
A storage area 12 for storing characters and the like input by handwriting from the liquid crystal tablet 10; a character recognition unit 16 as image data conversion means for recognizing the input characters and converting the input characters into character code data having codes. A dictionary 18 for storing a code of a character to be referred to at the time of the recognition, an editing processing unit 20 for performing a series of editing processes such as deletion and addition of a character,
And a control unit 14 for controlling processing of the entire apparatus.

Then, the liquid crystal tablet 10 and the storage area 1
2 and the control unit 14 are electrically connected to each other, and the character recognition unit 16 and the edit processing unit 20 are connected to the control unit 14.
And the dictionary 18 is electrically connected to the character recognition unit 16.

Next, the handwriting input device 22 of the present embodiment
Will be described.

FIG. 3 is a flowchart for explaining the flow of the processing according to the present embodiment. In FIG. 3, first, an input mode for inputting characters is set (S1), and the user inputs characters by handwriting (S30). For example,
When "confirm when determined" is input, a character string input by handwriting (hereinafter, referred to as a character string) is recognized by the character recognition unit 16 with reference to the dictionary 18 (S32).
The recognized result is displayed on the liquid crystal tablet 10 as shown in FIG. 2A (S34). Here, FIG.
The black square in a means a cursor.

Next, it is determined whether the correction mode button has been pressed (S36). Then, when the user presses a correction mode button (not shown) displayed on the liquid crystal tablet 10 with a projection such as a pen (S36: Y), the mode is switched from the input mode to the correction mode (S3).
8).

Next, it is determined whether or not the character string displayed on the liquid crystal tablet 10 has been pressed (S40). If it is determined that the character string has been pressed (S40: Y), the number of times the character string is pressed is stored in the storage area 12. It is stored (S42). For example, in consideration of a case where the character string displayed on the liquid crystal tablet 10 “Tell me when I decide” is changed to “Tell me as soon as I decide,” “Ta” in the character string is pressed once. If so, it is determined that a correction instruction for the character "ta" has been given, and one press of the character "ta" at the storage area
2 is stored.

Incidentally, the processing of S40 functions as the character code data designating means of the present invention.

Then, "ta" is deleted (S44), and as shown in FIG. 2b, "ra", which is the character after the deleted character "ta", moves to the left, and the cursor also moves to that position. I do.

Then, a space is inserted before the character "ra" by the number of times that the space is stored in the storage area 12 (in this case, one space) (S46). The result is shown in FIG. 2c.

Incidentally, the processing of S42 to S46 functions as the correcting means of the present invention.

Then, it is determined whether a character string has been input (S48). However, in this case, since nothing has been input, it is determined that no character string has been input (S4).
8: N) Other processing is performed (S56), and the processing ends.

Next, the character "ra" is pressed to delete the character "ra" and insert the corrected character string "as soon as possible" (S40: Y). In this case, since the corrected character string "soon immediately" is longer by three characters than the character string "tar" before correction, the character string is pressed four times including the shortage of three characters. Then, the number of presses 4 is stored in the storage area 12 (S
42).

In the same manner as in the previous case, "ra" is deleted in S44, the cursor is moved as shown in FIG. 2d, and the number of spaces (four in this case) is inserted as many times as spaces are stored in the storage area 12. (S46). The result is shown in FIG. 2e.

Since the deletion of the character string before the correction and the securing of the space for the character string after the correction have been completed, the operation of inputting the character string to be corrected "immediately" at the space insertion position is started. .

Since there is already enough space to overwrite a character string, if a handwritten character is written in the space part by hand as soon as possible, it is determined that a character string has been input (S48: Y). ), The mode is automatically switched from the correction mode to the input mode (S50). Then, a new handwritten character string is input on the liquid crystal tablet 10 so as to be overwritten on the space. Then, a known character recognition process is started (S52), the result is displayed on the liquid crystal tablet 10 (S54), and a series of operations is ended.

As is apparent from the above description, the handwriting input device according to the present embodiment, which displays the input result at the position where the handwriting is input, stores the number of pressed characters when correcting the character string. 12, the space for the number of times of pressing is automatically inserted after deleting the pressed character, so that the user can easily make correction.

If it is determined in S36 that an instruction other than the correction mode switching has been made (S3
6: N), and it is determined whether or not a character string has been input (S4).
8) If it is determined that there is no character string input (S4
8: N), other processing is performed (S56). Also, S4
0, if it is determined that an instruction other than the pressing of a character has been issued (S40: N), other processing is performed (S40).
56). Examples of other processing include processing such as turning off the power of the handwriting input device.

In the present embodiment, if it is determined in step S48 that a handwritten character has been input, the mode is automatically switched from the correction mode to the input mode. It may not be switched to the input mode.

[0031]

As is apparent from the above description, according to the handwriting input device of the first aspect of the present invention, the correcting means deletes the character code data designated by the character code data designating means. At the same time, a space is automatically inserted at the deleted position to correct the character code data, so even if you input image data such as characters by mistake, enter the space to insert the correct image data The image data can be easily corrected without the need to perform the operation.

[0032] According to the handwriting input device of the second aspect, the character code data instructing means instructs a plurality of times at the position where the character code data is deleted, and the correcting means in this case designates the instruction. Since the character code data is deleted and a plurality of spaces are inserted at the deleted position to correct the character code data, the user can more easily correct the image data.
