Description

Description: TECHNICAL FIELD The present invention is capable of displaying a view window display magnification and another display magnification differently on a display output unit capable of view window display, and further displaying on the display. ing. When inputting the view window information and other displayed information from the input device for editing, the input position information is converted according to the display magnification so that it can correspond to the position where the information is stored. The present invention relates to a text editing device.

[Technical Background of the Invention] Conventionally, it has been common to display a view window on the same display screen. However, in many cases, the display magnification in the view window is the same as the display magnification in other parts. Therefore, for example, when displaying a sentence equivalent to one A4 page on the entire display and using a part of the screen to set a view window to display other sentences, if the display magnification is the same, naturally the view window is displayed. Only a part of the A4 page can be displayed in.

For this reason, reduce the view window display magnification,
If the A4 page can be displayed in the view window, the entire A4 page can be displayed in the view window.

However, in this case, you may want to edit the A4 page displayed in the view window at the same time as editing the original page other than the view window. Normally, when editing the information (character string of a sentence) displayed on the screen, an input device such as a tablet is used as a method of indicating the position of the character string to be edited on the screen. Since the resolution of is physically fixed and the position coordinates of the input device itself are also physically the same resolution, the A4 page displayed in the view window and the position other than the view window for editing the page There is a problem in that it is necessary to have separate input devices.

[Object of the Invention] It is an object of the present invention to provide a text creation device that solves such problems.

[Structure and Effect of the Invention] The present invention edits, for example, an A4 page displayed in the view window at the same time as the original page other than the view window using the above-mentioned physically fixed resolution tablet. The feature is that the image position is converted according to the magnification only when the position of the view window is instructed so that the same as other parts in the view window. Can be edited.

That is, in the present invention, even in an input device having a physically fixed resolution, input position information (coordinates) to be input is
By performing magnification conversion processing on partial input position information (position coordinates in the view window) of the corresponding screen, it is possible to convert the resolution into an input device (for example, a tablet) so that the view window Also allows the editing processing to be performed in the same manner by the same input device as the other parts.

As a result, different sentences can be edited at the same time on the same screen, and the efficiency of creating and editing a sentence can be greatly improved.

Moreover, the editing accuracy according to the magnification can be obtained.
This is, for example, in the view window, a text of 20 dots x 20 dots, which is a character composed of 40 dots x 40 dots for each character other than the view window, is reduced by half in both length and width. At this time, the coordinate information input from the input device is also 40 dots x 40 in areas other than the view window.
The dots corresponded to one character, but in the view window, the input coordinates corresponding to 20 dots x 20 dots for each character can be obtained by the magnification conversion process, so that it is the same as the area other than the view window in the view window. Exactly 1
You can also specify the edit range for each character.

[Embodiment of the Invention] FIG. 1 is a configuration block diagram showing an embodiment of the present invention. Further, FIG. 2 is a display example showing a part of the display screen.

9 in FIG. 2 is an example in which one A4 page is displayed on the display, and 10 is a view window set in a part of the screen 9, and the other A4 one page is reduced and displayed in the view window. The scale factor of is different.

The operation of FIG. 1 in the case of FIG. 2 will be described below.

First, information for displaying a sentence at a magnification of 1 is input from the input unit 2 on the screen 9 of FIG. 2, and the information to that effect is transferred to the magnification conversion output unit 6 via the information processing unit 4. To be done. When displaying one A4 page on the screen 9, the information processing unit 4
A process of reading a sentence instructed by the input unit 2 from the information storage unit 5 is performed.

In the information storage unit 5, for example, in the case of text data for each document, it is stored as a character code. In this case, the same applies not only to the document name unit but also to the document page unit (sentence).

The information processing unit 4 transfers the text data read from the information storage unit 5 to the magnification conversion output unit 6.

The magnification conversion output unit 6 will be described later based on the text data (character code data) based on the target screen to be output (in this case, the information of the screen 9; the display screen position) and the magnification information (1 times from the above). Write the output image to the screen memory. Since the text data is code data as described above, the character image to be written on the screen memory is changed to a dot image by accessing a character pattern (40 × 40 dots per character) as is generally done. Take out. This dot image is sequentially written in a designated position on the screen memory at a designated magnification (1 in this case). When this writing is completed, the output section 7 outputs the data to the display 8.

Next, a case of displaying a reduced sentence on the view window 10 will be described. First, the reduced document name (page), the reduction ratio, and the display position of the view window 10 on the screen 9 are input from the input unit 2. The reduction ratio and the display position are transferred to the magnification conversion output unit 6 via the information processing unit 4. Also,
For the reduced document name (page), the information processing unit 4 reads the corresponding sentence page from the information storage unit 5 to obtain text data (character code). Then, the text data for reduced display read out from the information storage unit 5 is sent to the magnification conversion output unit 6.

The magnification conversion output unit 6 writes the text image information to the screen memory 11 in the same manner as described above, but in this case, a reduction instruction (in the case of FIG. 2, 1/2 in the horizontal and vertical directions, that is, 1 in area) /
4) is specified, the text data (character code) changes to the character pattern (as described above,
40x40 dots) is accessed and converted to a character dot image, then the horizontal and vertical directions are reduced by half, so the character dot image is converted from 2 dots to 1 dot (horizontal, horizontal,
The image is 20 x 20 dots (both vertically) and is written sequentially to the specified position on the screen memory. The method of converting 2 dots to 1 dot may be a generalized method. For example, if both 2 dots are ON (“1”), 1 dot is turned ON,
If both dots are OFF (“0”), turn ON 1 dot 2
If both dots are OFF (“0”), one dot may be turned OFF, and if either one is OFF and one is ON, it may be turned ON or OFF alternately.

FIG. 3 shows a configuration example of the screen memory.

If the screen memory is 2000 dots horizontally and 3000 dots vertically, for example, if the text of one page of A4 is 50 dots wide and 75 lines for each character 40 dots x 40 dots, from the upper left position of the memory If you write it in sequence, you can write one page of A4 text. Then, in order to display this A4 one-page sentence at one magnification, if the display can also display 2000 × 3000 dots, the A4 one-page can be displayed exactly. Further, the information for displaying the view window is written in the screen memory. In the case of, the size of the view window is 1000 × 1500 dots. In this view window, the character of 40 dots x 40 dots is 50 characters wide (20
00 dots), 75 lines (3000 dots) of A4 one-page text can be written with 1/2 horizontal 2000 dots (2 dots converted to 1 dot) and 1/2 vertical 3000 dots (2 Each dot is converted to 1 dot and written), and the area is reduced to 1/4.

As a result, one character is 20 dots × 20 dots in the horizontal direction of 50 dots.
Characters and 75 vertical lines can be displayed in the view window.

Next, when the characters displayed on the display 8 are edited, for example, corrected, inserted, or deleted, the tablet 1 to the screen 9
The position corresponding to the character displayed in is input, the corresponding character in the information storage unit 5 is designated from the position information, and the editing process is performed.

FIG. 5 shows a tablet 1 having a resolution of 2000 × 3000 (mesh is 2000 × 3000). This tablet 1
Then, one dot designated by the pen corresponds to one dot on the display 8. That is, in the case of a single copy display, the position corresponding to the position designated by the pen can be directly associated with the character of one page in the information storage unit 5. Therefore, in the case of the display display 9 (screen 9 in FIG. 2), there is a one-to-one correspondence (however, in screen 9, one character is 40 × 40 dots, and the position of the pen instruction is 40 × 40, which corresponds to one character. It can be done. When designating one page of characters displayed in the view window (view window 10 in FIG. 2), 12 areas of the tablet 1 (see FIG. 2)
Equivalent to 10) corresponds to the instruction. However, since the range of 12 is only 1000 x 1500 mesh (25 x 37.5 lines per character 40 x 40 dots), display 9
Similar to the area of, make 40 × 40 correspond to one character, and
If the mesh and one character correspond one-to-one, the tablet position 13 corresponds to the position 15 of the document shown in the view window 10 in FIG. Position 14 can only correspond to position 16 in FIG. 4 (b) as it is, and although view window 10 is reduced to display one A4 page, FIG. 4 (b) is displayed.
The 17 positions of are not indicated.

Therefore, the pen coordinates on the tablet 1 are the magnification conversion input unit 3
Input to the magnification conversion input unit 3, the information processing unit 4 is accessed and the display position information of the view window 10 (screen 9
Position and display magnification information (in view window 10,
Both horizontal and vertical are reduced by half, and 1 character 20 dots x 20 dots) is returned. As a result, the input position coordinates from the tablet 1 are converted by identifying the positional relationship between the screen and the tablet and the magnification. That is, in the scale factor conversion input unit 3, in order to indicate the position 17 in FIG. 4 (b), the position of the tablet input position 14 is reduced by 1/2 in the horizontal and vertical directions. Corresponding (1 character on screen 9
40 dots x 40 dots twice), by converting the tablet input position to that position, the 4th position at the tablet position 14
It becomes possible to specify the 17 positions shown in FIG. In this way, the magnification conversion input unit 3 performs conversion of the input coordinate position from the input device according to the display magnification of the screen 9,
Even if the magnification on the view window 10 differs from that on the screen 9, the position of the character string in the information storage unit 5 can be set in the same manner as the instruction on the screen 9.

[Modification of the Invention] In the present embodiment, the tablet and the display screen 9 have a one-to-one correspondence, but they do not necessarily have to have a one-to-one correspondence, and the resolution of the tablet and the display or information storage unit Even if the resolutions are different, it may be converted by the magnification conversion input unit. Further, in the embodiment, the view window magnification is 1/2 and 2 times, but it may be any magnification. In this way, the conversion corresponding to the magnification may be converted by the magnification conversion input unit and the magnification conversion output unit.

Further, in the embodiment, the size of the view window is displayed on the display screen.
Although it is set to 1/2, this may be any size. Although one view window is provided in the description, a plurality of view windows may be provided on the same screen, and it is sufficient that the information processing unit can identify which view window is multiplied and how many times.
Further, although it has been described that one screen memory is provided, a memory for a display screen and a memory for a view window may be separately provided and displayed to increase the processing speed.

In the embodiment, the details of the magnification conversion output unit for halving or doubling when writing to the screen memory are not described, but this can be done by a conventional method.
