Description

The present invention relates to a document editing apparatus that handles characters as image information.

[Prior art]

The conventional Japanese editing device has a main purpose of obtaining a clear copy output from a printing device, and takes a method of encoding a character and inputting it into a computer from a keyboard.

As a reference for this type of technology, there is JP-A-61-145.
630 and JP-A-61-67125.

[Problems to be solved by the invention]

The conventional Japanese editing device does not pay much attention to the point of inputting text while considering it. Therefore, when inputting kanji, it is necessary to input kana to convert into kanji, and it is necessary to intervene by humans by selecting homonyms and punctuation of bunsetsu. Also,
There is also a method of entering only kana and performing batch conversion into kanji, but there is a problem that it is hard to see when a human observes during the text input.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document editing apparatus that allows characters such as kanji and kana to be input as an image and to use the same editing function as in the conventional image with this image as it is.

[Means for solving problems]

In order to achieve the above object, the present invention provides a character input device for inputting handwritten characters as image data including a stroke number and dot data in an entry frame of which size is defined in advance, and an input device entered in the entry frame. A document editing apparatus that includes an input character storage memory that stores image data in association with a pointer on a character-by-character basis, and uses the pointer of the image data for the input character unit, which is a document editing device that edits the input character. It is characterized in that the input characters are edited as they are in the image data by performing editing processing such as insertion, deletion, deletion and overwriting processing of the image data in units of the entry frame.

[Action]

The document editing apparatus according to the present invention stores input image data in an input character storage memory in correspondence with a pointer, and uses the pointer to insert, delete, erase and overwrite image data for each entry frame. By performing the editing process, the input character is edited with the image data as it is.

〔Example〕

FIG. 1 is a diagram showing an embodiment of the document editing apparatus of the present invention. This document editing device comprises a central processing unit 1, a memory 2, a display device 3, a disk device 4, a keyboard 5, a printer 6, and a character input device 7.

Central processing unit 1 ... Character editing processing is performed by a program in the memory 2.

Memory 2 ... Stores programs and input characters as image data.

Display device 3, keyboard 5 ... The display device 3 displays characters, and the keyboard 5 gives instructions for processing such as document editing.

Disk device 4 ... Used as an external memory. Stores application programs and documents with edit words.

Printer 6 ... Prints the edited document.

Character input device 7 ... Tablet. The tablet surface is pressed by a worker's hand or an instruction tool, and information on the pressing point is captured as coordinates. Coordinates are on the tablet surface
The coordinates (x, y) when defined in the Cartesian coordinate system of XY.
Therefore, coordinates along the shape of the character are captured for each sample point on the tablet. This character capture is performed in stroke units. The stroke refers to a moving section in which a pen is continuously pressed when a character is traced with a pointing tool such as a pen. Therefore, in kanji input, when the kanji is written in the regular writing order, each kanji has the number of strokes equal to the number of kanji divisions. If it is a so-called one-stroke character,
The number of strokes is one.

Further, one stroke is composed of a dot length indicating the length of this stroke and character information (dot data) forming the stroke.

The number of strokes, the length of each stroke, and the dot data of each stroke are called image data. This image data may be created by the character input device 7, or the processing device 1 creates the image data if the character input device 7 is a device having only a simple information transmission function.

In the following, it is assumed that the character input device 7 outputs the X and Y coordinate values of the pressed point at a constant cycle when the pen is pressed,
Moreover, the interface with the processing device 1 is a serial interface, and the coordinate values are input to the processing device 1 by interruption. The processing device 1 takes in the coordinate data in the interrupt processing and stores it in the memory 2. This storage is an image data format, and the image data format is formed by the processing device 1 forming one coordinate value one after another and the processing after storing in the shared memory 2. There are two ways to do it.

The operation under the configuration of FIG. 1 will be described below.

FIG. 2 shows a flow of image data creation processing by the processing device 1. This processing is performed by storing the character in the memory 2 as coordinate values and then accessing the memory 2.

In FIG. 2, first, in step 21, it is confirmed that the pen is on the tablet, the number of strokes is set to 0, and the stroke capturing process is started (step 22). Then, the coordinate data is taken in until it is pen-up. (Steps 23 and 24) The number of dots of the stroke to be pen-up is stored and the next stroke is processed (step 25). When the character delimiter key is pressed (step 26), the character input is completed, the number of strokes is stored, and the data acquisition for one character is completed (step 27).

The processed data shown in FIG. 2 has a structure as shown in FIG. 3, and is composed of the contents shown in the character pointer area and the contents shown in the coordinate data area on the memory 2. One character corresponds to one character pointer, and this character pointer corresponds to a conventional character code. Each character pointer points to the coordinate data area of each character, and the coordinate data area includes the number of strokes, the number of dots, and dot data.
The number of strokes indicates the total number of strokes of this character, the number of dots indicates the number of dots for each stroke, and the dot data contains the coordinate value of each dot with the origin at the upper left of the character area.

As shown in FIG. 4 (a), the tablet has an area for one character on the board 41, and the upper left point is the origin. The size of the character is defined in advance, and an entry frame (indicated by a dotted line) is drawn on the screen in the size of the character and used as a unit on the screen. To display the entered character data,
By performing the processing as shown in FIG. 5 (steps 50 to 54) and multiplying the coordinate value by a constant (step 55), the coordinates are corrected so as to be within the defined size. The display on the screen is performed based on the character pointer area 30, and the coordinate data indicated by the character pointer is drawn with the upper left corner of the frame as the origin. A display example on the display screen 40 is shown in FIG.
A cursor is provided corresponding to the character pointer and the frame of the screen, and this is moved and used for editing. In the coordinate data area 31 indicated by the character pointer, a line feed, as shown in FIG.
Insert special editing codes such as page breaks and blanks instead of the number of strokes to reduce the amount of data.

In this way, the graphic data of a character is indicated by a pointer, and the pointer is used as a character code to edit the graphic data of the character.

FIG. 6 shows the insertion process. First, make a space for one character at the position where the character pointer is inserted (step 60), and add the coordinate data of the character to be inserted to the coordinate data area,
(Step 61), the character pointer is connected to the added area (Step 62). After the character pointer is inserted by performing such processing, if the changed portion of the character pointer is displayed again, one character is inserted on both the screen and the memory.

FIG. 7 shows the deletion process. Open the coordinate data area indicated by the position to delete the character pointer (step 7
0), then, after making it usable as another data area, the character pointer is deleted by closing the character pointer one character behind the character pointer at the position to be deleted by one character before (step 71).

FIG. 8 shows the erasing process. The position of the number of strokes at the beginning of the coordinate data area indicated by the position where the character pointer is erased is changed to a blank code (step 80), and the remaining coordinate data area is released (step 81). The display of the blank code is performed by clearing the inside of a frame of a predefined character size.

FIG. 9 shows the overwriting process. Overwriting is the addition of another stroke to an existing character. The coordinate data indicated by the character pointer of the character to be overwritten is copied to a new coordinate data area (step 90), and the stroke data to be added thereafter is added. Then, the coordinate data area originally indicated by the character pointer is released (step 91), and the character pointer is reconnected to a new area of the copy destination (step 92).

Since the basic editing process can be performed by the above method, the processes such as block deletion and move copy can be performed by moving the character pointer by changing the character pointer.

According to this embodiment, the character data of the image input from the character input device is put into two data structures of the character pointer and the coordinate data area, so that it is possible to edit the character by character. Editability by
There is an effect that it is possible to realize a Japanese document editing device that combines the ease of handwriting input.

〔The invention's effect〕

As described above, the document editing apparatus according to the present invention stores the input image data in the input character storage memory in correspondence with the pointer, and inserts, deletes, erases, and overwrites the image data in the entry frame unit using the pointer. It is possible to edit the input character as the image data by performing the editing process such as. As a result, it is possible to prevent the thinking person from interrupting the thinking due to the character conversion.
