Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to various character processing devices such as word processors, and more particularly to technology for enlarging and displaying input characters.

Conventionally, in order to enlarge characters in word processors, etc., there have been two methods: enlarging and displaying the characters to a reasonably predetermined magnification such as 4x x 2x x 2x, and a method that has recently been used in portable word processors. So, vertical and horizontal are nX
A method of specifying an enlargement size to arbitrarily enlarge the image by m times has been adopted.

For functions that specify one character position, such as quadruple-width and double-width, the magnification size is doubled and fixed, thereby reducing display and printing processing and reducing processing speed and machine costs. It has been taken.

Also, if you want to specify an arbitrary enlarged size of nXm times the vertical and horizontal enlargement, specify it in line units, and when giving a print instruction,
The amount of processing is reduced by ensuring that all of the specified nXm times the processing is performed in the same way in a series of processings.

Therefore, as shown in Figure 20, even when inputting characters to a line that includes characters specified as an arbitrary enlarged size, character input does not take into account the size of the enlarged characters, so the normal line Since you can enter the same number of characters as the second
As shown in Figure 1, when printing, enlarged characters sometimes exceeded the width of the paper and were omitted.

Therefore, when creating and editing a document, characters must be input while taking into account the result of enlarged printing, resulting in a problem of very poor operability.

This invention has been made in view of the above points, and aims to improve the versatility and operability of document creation.

(ii) In order to achieve the above object, the present invention provides a character processing device that is equipped with at least an input device and a display device, and can edit and proofread characters inputted from the input device by displaying them on the display device. means for instructing to enlarge each character, etc., displayed on a display device by an arbitrary magnification based on an instruction from an input device, and displaying the enlarged characters, which are instructed to be enlarged by the means, on the screen of the display device at that magnification.

FIG. 1 is a block diagram functionally showing a portion of this control unit related to character enlargement display control.

The part related to character enlargement display control in this control unit is located between the input device 1 and the display device 2.
02 display line expansion section 41. Format format information section 42.
Text buffer section 432 Displaying text information section 44.
Enlargement specification control section 45° enlargement size specification section 4B, enlargement size section 47. Cursor control unit 48. Key line buffer section 49
．． Character generator (CG) 50. Enlargement cutting section 51, position correction specifying section 52. It is composed of a text enlargement position correction/update section 53 and a display control section 2B.

The input device 1 is a keyboard, and as mentioned above, characters,
Input various key data such as line, cursor movement, 2 character enlargement, etc.

The input control section 25 discriminates various key data input from the input device 1, and transfers this data to each functional section according to the discrimination result.

When the input control unit 25 recognizes that the key data input from the input device 1 is character data, the character editing unit 40 receives this character data from the input control unit 25 and edits the character. .

The display line expansion unit 41 sequentially extracts data from the text buffer unit 43 and format information unit 42 and creates text information during one display.

Determines the horizontal arrangement of characters for one line.

The format information section 42 stores format information regarding formats, and outputs this to the display line development section.

The text buffer section 43 sets the normal character code, the character code when specifying enlargement, and the character code when specifying center alignment and bottom alignment enlargement as shown in FIGS. 8, 9, and 10. This data is temporarily stored.

The currently displayed text information section 44 converts the horizontal arrangement of characters determined by the display line development section 41 into a physical line with the size of one normal character as shown in FIG. 11 for one line.
The maximum vertical enlargement size is calculated and this is used as a logical line for this line, an enlarged size table and a display information table are created and output to the display line development section 41.

When enlargement is instructed by the input device 1, the enlargement specification control section 45 outputs the cursor information of the cursor control section 48 and the enlarged size of the enlarged size storage area 47 to the display line development section 41 as a display change.

The enlarged size storage area 4 is also used in the text buffer 43.
Output the enlarged size of 7.

When the enlarged size specifying section 4B receives an input to change the enlarged size from the input device 1, it receives this enlarged size data from the input control section 25, transfers it to the enlarged size storage area 47, and also transfers it to the display device 2. The message is output to the display control section 2B for displaying the message.

The enlarged size storage area 47 receives enlarged size specification data from the enlarged size specification section 46, stores this enlarged size, and outputs the enlarged size to the enlarged specification control section 45.

The cursor control unit 48 inputs cursor information to the input control unit 25.
, and input this into the character editing section 40 and display line expansion section 41.
．． It is output to the enlargement designation control section 45 and the display control section 26.

The line buffer section 4 temporarily stores data related to the line and outputs it to the display line development section 41 as required.

A character generator (CG) 50 stores character font data and outputs this font data to an enlarged cutout section.

The enlarged cutout section 51 transfers information such as the character code received from the display line development section 41 and the enlarged size table and display information table of the displayed text information section 44 to the display line development section 4.
Input via 1 and character generator (CG)
Character font data is searched and extracted from 50, enlarged characters are cut out based on this information, and enlargement processing is performed according to each enlarged size. Then, this data is passed through the display control unit 26 as display font data to the display bag! ! ! Display on 2.

When there is a key force for position correction from the input device 1, the position correction designation unit 52 receives this from the input control unit 25, and
Display control unit 2 instructs to display a message as shown in Figure 6.
Make it 6. Further, the text enlargement position correction update unit 5
This information is also output to 3.

The text enlargement position correction update section 53 outputs the input enlargement position correction data to the text buffer section 43 and the display line expansion section 41.

Next, the designation of enlarged characters for each character unit and its display method, which are the effects of this embodiment configured as described above, will be explained with reference to FIG. 4 and subsequent figures.

FIG. 4 shows the concept of lines when characters of different enlarged sizes coexist.

In this case, the character nmaX with the largest vertical enlargement size among the characters existing in one line is detected, and this is set as the enlarged size of this line. Other characters are treated as if they are contained within this line.

Furthermore, as shown in Figure 1, the next line is
The position will be "x times ax" lower. If lines are formed in this way, there may be large gaps between lines depending on the size of one character, but if consecutive character strings are arranged depending on the size of the characters, the line boundaries will be undefined. This makes it difficult to determine the continuity of character strings, so this processing method also improves operability.

Furthermore, since the continuity of character strings is not disrupted, there is an advantage that processing such as character search and recognition can be performed relatively easily.

Next, row changes will be explained with reference to FIG.

If you delete the character a of maximum size n wax in the character string shown in Figure 4 and change the maximum enlarged size of characters in one line, as shown in Figure 5, for example, The maximum character of the vertical enlargement size is detected again, and the recognition of the vertical enlargement size of this line is changed. Therefore, in the example of FIG. 5, the enlarged size of the row is changed to n.

Further, as shown in FIGS. 4 and 5, characters whose enlarged size is smaller than the maximum enlarged size are aligned by matching the upper sides of the lines.

Here, when changing the bottom alignment in Figure 6 and the center alignment in Figure 7, which will be described later, to the top alignment, as shown in the top alignment routine in the flowchart in Figure 15, the correction value of the characters in the line is changed. , and the text buffer 43 is also updated.

Moreover, the line spacing between this line and the next line is, as described above, the line spacing equal to the line spacing of one line of normal characters multiplied by the magnification of the maximum character on this line.

Therefore, from n wax times in Figure 4 to n8 in Figure 5
Change to double.

Next, bottom alignment of lines will be explained with reference to FIG.

When aligning enlarged characters to the bottom of a line, as shown in the bottom alignment routine in the flowcharts of Figures 6 and 15, the character with the maximum vertical enlargement size is set to the enlarged size of this line, and smaller enlarged characters , the diagonal line part (difference between the enlarged size of the in-line character and the maximum enlarged size) in Figure 1 is inserted as a correction value, so that processing is performed as if the enlarged characters were up to the shaded part.

The temporary enlargement size at this time is for detecting the character display position, and is unrelated to the actual enlargement of the character font.

FIG. 7 shows the case where the lines are aligned to the center of the row. This will be explained with reference to the center alignment routine in the flowchart of FIG.

In this case, as in the case of bottom alignment in FIG. 6, each character in a line is arranged at the center of the line using the concept of correction based on a temporary enlarged size.

In this case, the calculation method for the temporary enlargement size, that is, the correction value, is (maximum enlargement size - enlargement size of characters in the line)/2. Note that here, the enlarged size is the vertical enlarged size. In the above formula, the remainder may be rounded up or down.

Note that when the above-mentioned enlargement position correction is instructed by the position correction key of the input device 1, a message as shown in No. 16 is displayed on both sides of the display device 2.

Therefore, selecting "1" from this message display will change to top alignment, selecting "2" will change to bottom alignment, and selecting "3" will change to center alignment.

Next, the enlarged display method will be explained with reference to FIG.

As shown in Figure 11, the letters raJ are multiplied by 6x6, and
If there is a double "b" character, slice each character into 1x vertical physical lines, and calculate the cutting position for each character from its enlarged size as shown in the same figure (b). Create a display information table.

In calculating this cutting position, in addition to the enlarged size of one character, the enlarged size (correction value) for the previous correction is also used.

In the case of this character “b”, enlarge the size 2×2 with bottom alignment.
However, since the correction ranges from the top to 1.2 and 3.4, the correction value is set to "4". Therefore, the table is set so that the top four rows of the physical row slices are not cut out.

Then, when displaying, the font data that has been enlarged based on these tables and the enlarged character size is
The data is extracted and displayed according to the table value corresponding to the number of the physical row to be displayed.

Next, the method of specifying the enlargement size will be explained with reference to the flowcharts of FIGS. 12 and 13i.

When there is an input to change the enlargement size from the input device 1, the input is sent to the enlargement size specifying section 4 via the input control section 25 shown in FIG.
The instructions are transferred to 6. Expanded size specification section 1st on the 4th
A message as shown in FIG. 2 is displayed on the display device 2 through the display control section 26.

This display shows the previous enlarged size. Then, input of the enlarged size is accepted. The input new enlarged size is checked to see if it is the maximum size, is stored in the enlarged size storage area 47, and the process ends.

The method of specifying enlargement will be explained with reference to the flowchart of FIG.

When a character enlargement instruction is received from the input device 1, the instruction is transferred to the enlargement specification control section 45. The enlargement specification control unit 45 receives cursor position data from the cursor control unit 48,
The character address corresponding to this is calculated, and the text buffer 43 is changed to add an enlargement attribute (enlargement specification to the character at the cursor position) to the corresponding character, and the process ends.

After the change, a request is made to the display line expansion unit 41 to display the changed line, thereby realizing a change in display based on enlargement specification.

Next, the text buffer shown in FIGS. 8 to 10 will be explained.

First, the contents of the text buffer 43 are simply a series of character codes as shown in Figure 8 when enlarged characters are not specified, and when enlarged characters are specified as shown in Figure 9. An enlargement factor n (vertical) and 1 m (horizontal) is added to each image.

In addition, if temporary enlargement size correction such as center alignment or bottom alignment is performed, nX
In addition to m times, a correction magnification n' is also added at the same time.

In this way, enlargement is specified for each character and enlarged display is performed. This will be explained with reference to the flowchart of FIG. 17.

When the text buffer 43 described above is updated, the display line expansion unit 41 is requested to display the updated line.

The display line expansion unit 41 calculates the text buffer character address of the display requested line from the text buffer 4'5.

At that time, the format/format data of the relevant line to be displayed is sequentially extracted from the format information section 42, and 1
The possible layout range of characters for a line is calculated and determined.

Once the display character for one line is determined, this character is then taken out from the text buffer 43 and it is determined whether it is a character code or not.

If it is a character code, it is set in a character table with horizontal enlargement size according to the specified magnification. This operation is then repeated for one line.

If the previous determination result is not a character code, it is determined whether or not it is an enlargement instruction, and if it is an enlargement instruction, the enlargement size is fetched and set in the table. If it is not an enlargement instruction, other attribute processing is performed in accordance with the instruction.

In the case of an enlargement instruction, it is further checked whether the enlargement size set in the table is to be corrected.

Then, when the correction is completed, the corrected size is fetched and set in the table. If there is no correction, a correction size of 0 is set in the table. This operation is then repeated for one line.

When the processing for one line is completed, the maximum vertical enlargement size is first detected from the character table and enlargement size table shown in FIG. Then, the physical row number is calculated from the requested row number. Then, a display row is calculated based on the calculated physical row number.

Next, a character is extracted from the one-character table and enlarged using an enlarged size.

Then, character data is extracted using the display information table and set in the display buffer. Then, perform this operation on the physical lines (line 1 to line 6 in Figure 11).
Repeat until the end and display this at the same time.

This process is then repeated for one line (logical line) and displayed.

FIGS. 18 and 19 are display examples displayed on the screen of the display device 2 by the above-described method, respectively.

Each character is enlarged arbitrarily, and when printing, the same print result as this display is obtained.

In this way, you can specify enlargement for each character, and it is displayed at the actual enlarged size and printed as is.
When printing, enlarged characters will not be lost beyond the paper width, and there is no need to input characters while considering the enlarged printing results when creating and editing documents as in the past. A character processing device with very high operability is obtained.

As explained above, according to the present invention, it is possible to specify enlargement for each character, and it is also possible to display the actual enlarged size, so it is possible to create a wide variety of documents with simple operations. Can be done.
