Abstract

PURPOSE:To provide the title device with editing property based upon character codes and easy input based upon hand-written characters by using hand-written character image data and processing in each image data in the succeeding edition processing. CONSTITUTION:After confirming a pen put on a tablet 7, stroke fetching processing for the number D of strokes is started and coordinate data obtained up to pen-up are inputted. At the time of pen-up, the number of dots of the stroke is stored in a memory 2 to execute the succeeding stroke processing. When a character segmenting key is depressed, the input of a character is completed and the number of strokes is stored in the memory 2 to end the data input of one character. The graphic data of a character of an image inputted from the table 7 are pointed out by a pointer and the pointer is processed as a character code to edit the graphic data of the character.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document editing device that handles characters as image information.

[Prior art]

Conventional Japanese language editing devices, whose main purpose is to obtain fair print output from a printing device, take a method of encoding characters and inputting them into a computer from a keyboard.

As a reference for this type of technology, JP-A-61-
There are No. 145630 and JP-A No. 61-67125.

[Problem that the invention seeks to solve]

Conventional Japanese language editing devices do not give much consideration to the point of inputting sentences while thinking about them.

Therefore, when entering kanji, it is necessary to enter the kana and convert it to kanji, and human intervention is required to select homonyms and specify segment breaks, which can disrupt thinking. There is also a method of inputting only kana and converting it to kanji all at once, but this also has the problem of being difficult to read when a human observes the text while inputting it.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document editing device that allows characters such as kanji and kana to be input as images and to use editing functions similar to those of the prior art without changing the images.

[Means for Solving the Problems] The present invention provides a handwritten character input device and a system that converts handwritten characters from the input device into image data (consisting of the number of strokes constituting one character, the number of dots for each stroke, and dot data). It consists of a character storage memory for storing information (information) and an editing means for editing the characters stored in the character storage memory character by character.

[Effect]

In the present invention, handwritten characters are treated as image data,
The subsequent editing process is performed in units of image data.

〔Example〕

FIG. 1 is a diagram showing an embodiment of a document editing device of the present invention. This document editing device includes 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 . . . performs character editing processing using a program in 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 external memory.

Store application programs or edit language documents.

Printer 6: Prints the edited document.

Character input device 7... is a tablet. The tablet surface is pressed by the worker's hand or an indicating tool, and the information of the pressed point is taken in as coordinates. Coordinates are the coordinates (x, y
), therefore, the coordinates along the shape of the character are captured for each sample point on the tablet. This character import is
It is done in stroke units. When tracing a character with an indicating tool such as a pen, a stroke refers to the area that the pen is moved by pressing continuously. Therefore, in kanji input, if the kanji is written in the regular stroke order. has the number of strokes per kanji character equal to the number of sections of the kanji character.If the character is written in one stroke, the number of strokes is one.

Furthermore, one stroke consists of a dot length indicating the length of this stroke and character information (dot data) that constitutes 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 character input device 7 may be used as a mere piece of information. If the device has only a transmission function, the processing device 1 creates image data.

In the following, it is assumed that the character input device 7 outputs the X and Y coordinate values of the pressed point at regular intervals when the pen is pressed, and that the interface with the processing device 1 is a serial interface. It is assumed that coordinate values are input to the device 1 by interruption. The processing device 1 takes in the coordinate data and stores it in the memory 2 in this interrupt process. This storage is in an image data format, and the image data format is formed in a manner in which the processing device 1 sequentially forms each coordinate value each time it takes in one coordinate value, and - after storing it in the storage memory 2.
There are two ways to form it through processing.

The original operation of the configuration shown in FIG. 1 will be explained below.

FIG. 2 shows the flow of image data creation processing by the processing device 1. This processing is performed by storing characters 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, and the stroke number is set to O, and the process begins to capture strokes (step 22), and coordinate data is captured until the pen is raised.

(Step 23.24) String of being pen up
゛Memorize the number of dots in the loaf and process the next stroke (step 25) The 0 character separator key is pressed (
Step 26) completes character input, memorizes the number of strokes, and completes data import for one character (Step 2
7).

The data after processing according to FIG. 2 has a structure as shown in FIG. 3, and consists of the contents shown in the character pointer area on the memory 2 and the contents shown in the coordinate data area. 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 the respective character, and the coordinate data area consists of 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 in each stroke, and the dot data contains the coordinate values of each dot with the upper left of the character area as the origin.

The tablet has 1 on the board 41 as shown in Figure 4 (a).
There is an area for characters, and this upper left point is the origin. The size of the characters is defined in advance, and a frame (indicated by a dotted line) is drawn on the screen with the size of the characters as a unit on the screen. When displaying the input character data, press the fifth button.
By carrying out the processing shown in the figure (steps 50 to 54) and multiplying the coordinate values by a constant (step 55), the coordinate values are corrected so that they fit within the defined size frame.0 The display on the screen is based on the character font area 30. The coordinate data indicated by the character pointer is displayed by drawing the coordinate data indicated by the character pointer, using the upper left corner of the cotton as the origin. An example of the display on the display screen 40 is shown in FIG. 4(B). A 0 character pointer and a cursor are provided corresponding to the frame of the screen, and these are moved to be used for editing. Further, in the coordinate data area 31 indicated by the character pointer, as shown in FIG. 3, special editing codes such as line feed, page break, and blank are entered in place of the number of strokes to reduce the amount of data.

In this way, by indicating the character graphic data with a pointer and using the pointer as a character code, the character graphic data can be edited.

Figure 6 shows the insertion process. First, create a space for one character sentence at the insertion position of the character pointer (step 60), add the coordinate data of the character to be inserted to the coordinate data area,
(Step 61), and connect the character pointer to the added area (Step 62). After performing such processing and inserting a character pointer, if the changed location of the character pointer is redisplayed, one character will be inserted both on the screen and in the memory.

FIG. 7 shows the deletion process. The coordinate data area indicated by the position to be deleted by the character pointer is released (step 70).
), then after making it available for use as another data area,
1 from the character after the character pointer at the position to be deleted
Move the character pointer forward by characters and delete the character pointer (Step 7)
1).

Figure 8 shows the erasing process. Change the number of strokes at the beginning of the coordinate data area indicated by the position to be erased by the zero character pointer to a blank code (Step 80), and release the remaining coordinate data area (Step 81). . The blank code is displayed by clearing the space within the frame for a predefined character size.

FIG. 9 shows the overwriting process. Overwriting means adding another stroke to an already existing character. Copy the coordinate data indicated by the character pointer of the character to be overwritten to a new coordinate data area (step 90), and then add stroke data to be added. Then, the coordinate data area originally indicated by the character pointer is released (
Step 91), and reconnect the character pointer to a new copy destination area (Step 92).

Basic editing processing can be performed using the methods described above, and by combining these methods, processing such as block deletion, movement, and copying can be performed by changing the movement of the character pointer.

According to this embodiment, by putting the character data of the image input from the character input device into two data structures: a character pointer and a coordinate data area, it is possible to edit character by character. Editability and
This has the effect of realizing a Japanese document editing device that facilitates handwritten input.

〔Effect of the invention〕

According to the present invention, since characters are treated as image data, it is possible to edit documents at the level of this image data.
