Abstract

PURPOSE:To eliminate editing in a row unit for an expression, a chemical formula, etc., and executing real image editing on a picture without intermitting thought by using variable length cursor covering plural rows, and collectively executing a necessary editing action for the plural rows. CONSTITUTION:When an expression/chemical formula mode is selected, a CPU 22 executes a 1/2 line feed mode. The mode interpolates a 1' row and a 2' row in the middle of the normal rows 1 to 3, and to execute the line feed of a cursor in 1/2-row' unit. In such a case, since an image overlaps for a half rows, a display control is executed by an exclusive logical sum. In size setting, when a [CTRL+UP] key operation is executed in a condition in which a vari able length cursor CS at a standard size is on a present row, the CPU 22 up ward extends the cursor by 1/2 rows. Continuously, by repeating the same opera tion for three times, the cursor upward extends by 2 rows as a whole. Next, when a [SHIFT+DOWN] key operation is repeated for twice, the cursor CS downward extends by 1/2X2, that is, downward extends by one row as a whole. Thus, the collective editing is executed by the set row portion.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image editing method for editing an image on a display screen and an image editing device such as a word processor or a personal computer 1 that implements this method. In particular, the present invention relates to an image editing method and apparatus effective for editing images of mathematical formulas, chemical formulas, etc.

[Prior art] Generally, mathematical formulas, chemical formulas, etc. required in the departments of mathematics, physics, chemistry, pharmacy, and engineering in general have text-like properties (-dimensional arrangement, and when inserting or deleting characters are Because it has a very unique structure that has both a graphical property (a two-dimensional arrangement) and a graphical property (a property that involves movement into the It is inherently difficult to edit images with the above-mentioned unique structure using an image editing device.

Specific examples include those shown in FIGS. 24(a) and 24(b). If you consider how to move characters when inputting these and then inserting or deleting them into the ■■■00 part, the difficulty will be obvious.

By the way, there are two conventional methods for editing images of mathematical formulas and chemical formulas:

One of them is called the command method, in which input,
A special command string is used when editing, and when printing, the image of a mathematical formula or chemical formula is printed.

Another method is to add special control codes, etc. For example, fractions are entered on separate lines, and special control codes are added for superscripts and subscripts. That's what I do. After inputting the information in this way, a half-line break or the like is specified and printed, so that the image is printed in a form that is close to the actual image.

[Problems to be Solved by the Invention] However, in such conventional image editing methods, editing images of mathematical formulas, chemical formulas, etc. (requiring complicated procedures and a great deal of labor); This causes a problem in that the inputted information and the printed result do not correspond as expected, and the process must be repeated many times.

As a result of analyzing the above-mentioned problems, the present inventor has discovered that images of mathematical formulas, chemical formulas, etc. can be freely manipulated on a display screen without interrupting thinking in the same way as images of mathematical formulas, chemical formulas, etc. can be freely manipulated on paper. We came to the conclusion that it would be good if we could create a real image editing system that could print the images on both sides of the display as they were.

Based on this conclusion, the following two points in particular have been major obstacles in realizing a real image system for mathematical formulas, chemical formulas, etc.

Specifically, conventional image editing methods are based on editing line by line. However, in most cases, mathematical and chemical formulas span multiple lines and involve operations such as inserting or deleting a part of the formula, so it is difficult to - In the process of editing line by line, a problem arises in which thinking about the mathematical formula or chemical formula itself has to be interrupted.

The formula also includes superscripts, subscripts cx, and “.

X6, etc.) appear frequently, but conventionally, these inputs are usually converted to superscripts, subscripts, etc. after specifying the range. This creates the problem of having to think about it, and having to stop thinking about mathematical formulas.

This invention was made to solve the above problems, and in the same way that images such as mathematical formulas and chemical formulas can be freely handled on paper, these images can be displayed on a display screen without interrupting thinking. The present invention provides a new image editing method and device that allows real image editing to be freely manipulated.

[Means for Solving One Problem] That is, in an image editing method according to one invention, when editing a part of an existing image on a display screen in a desired mode across multiple lines, first, The cursor size, which serves as an image input index, is set in correspondence with the number of lines to be edited, and then the number of lines corresponding to the variably set cursor size is subjected to batch editing.

In this invention, the method of variable setting of the cursor size is such that it can be extended downward from the reference position, or it can be extended either upward or downward from the reference position. Although the design may be changed as appropriate, it is preferable to extend it from the reference position in any direction upward or downward from the viewpoint of ease of variable setting.

In addition, if the cursor is of a type that can be extended both vertically and vertically from the standard size, from the perspective of easily understanding the cursor position when returning the cursor size to the standard size, the cursor with variable size settings will be expanded to the standard size. It is preferable to take measures such as dividing the current line where the cursor is located as a boundary using different display modes such as different colors and patterns.

Furthermore, desired editing modes in the present invention include insertion and deletion of spaces, settings for moving areas and copying areas, and the like.

As shown in FIG. 1(a), for example, an image editing device which is an invention for realizing this invention includes an image input means 1 including a cursor operation section 2 serving as an image input index, and an image editing device. A storage means 3 that stores target characters, symbols, etc. in advance, a display means 4 that displays an image at a location corresponding to the cursor C8 position on the display screen 4a, and a display based on a signal from the cursor operation section 2. Cursor control means 5 for controlling the cursor C8 on the display screen 4a of the means 4, and image editing for searching the contents of the storage means 3 based on the signal from the image input means 1 to create a display image on the display screen 4a. The cursor operation unit 2 is provided with a cursor size conversion operation unit 7, and the cursor control unit 5 is provided with a cursor size conversion operation unit 7 based on a signal from the cursor size conversion operation unit 7. A variable length cursor creation unit 8 is provided in which a standard size cursor C8 is set as a variable size cursor C8 spanning multiple lines.

In such technical means, the image input means 1 is usually a keyboard, but is not limited to this, and can be used in a wide range of ways, such as using an index pen, optical reading means, or audio. Examples include:

In addition, when using a keyboard as the image input means 1, it is possible to provide dedicated keys for special characters and symbols used in mathematical formulas, chemical formulas, etc., but from the viewpoint of preventing the keyboard from increasing in size, It is preferable to assign the above-mentioned special characters to existing keys. In this case, in consideration of input operability, it is preferable to directly assign frequently used keys to existing keys, and to indirectly assign the remaining keys so that they can be selected. Furthermore, considering operability, when assigning frequently used special characters and symbols to existing keys on the keyboard, select keys whose shapes are similar to the special characters and symbols to be assigned. When indirectly assigning special characters and symbols to existing keys on the keyboard, it is more preferable to set and assign characters with similar shapes to the same group. In particular, for objects with a special shape (hexagonal) such as a benzene nucleus, you can change the key position by assigning a partial symbol of the hexagon to a key at a position corresponding to the shape of the benzene nucleus. Input operability can be improved to the extent that it can be grasped intuitively.

Furthermore, as the cursor operation section 2, the image input means 1
A dedicated key may be provided on the keyboard, or a dedicated mouse may be used.

Furthermore, the storage means 3 may be of any type as long as it stores image data necessary for editing mathematical formulas, chemical formulas, etc. in a readable manner.

Furthermore, if the display means 4 has a display screen 4a on which the cursor C8 indicating the index position of the input image moves in accordance with the operation and the input image is displayed, the CR
You can select as appropriate, including T-display.

As for the cursor control means 5, the cursor C
As long as the variable length cursor creation section 8 is provided in addition to the movement control section 8, the design can be changed as appropriate, and these functions are usually realized by a computer. In this case, it is necessary to add to the cursor operation section 2 a cursor size conversion operation section 7 for instructing how to variably set the cursor C8. Further, the image editing control means 6 may be designed by changing its design as appropriate, such as implementing the function with a computer, as long as it can execute the editing mode necessary for displaying images such as mathematical formulas and chemical formulas.

Furthermore, regarding the movement control section of the cursor control means 5, from the viewpoint of realistically expressing images of mathematical formulas, chemical formulas, etc., it is necessary to move the cursor C8 to a new line in units of 1/2 line in a mode that handles mathematical formulas, chemical formulas, etc. However, in order to prevent unnecessary deletion of displayed images due to adjacent rows overlapping each other, it is necessary to perform an EOR operation on the overlapping images in the image editing control means 6. It is necessary to take measures such as controlling the display by

In addition, in an image editing method according to another invention, when editing a unit image in which a conversion target image part that needs to be converted to a format different from the standard display format on the display screen is included in the entirety or at least in the rear side, first, the unit image is After temporarily editing the image in the standard display format, the image part to be converted is converted to the predetermined format by performing a predetermined image conversion operation that does not involve operating a cursor that serves as an image input index on the display screen. This will be converted and then edited.

In this invention, the image portion to be converted is as follows:
When the standard display format is full-width English characters, examples include quarter-width superscripts, middle scripts, subscripts, Greek letters, German letters, italic or cursive English letters, etc. Further, when the reference display format is a standard size symbol, there is a method that converts this into a symbol of a vertically variable length size.

An image editing device that is one invention that realizes this invention has a cursor operation unit 2 that serves as an image input index.
an image input means 1 including an image input means 1; a storage means 3 in which characters, symbols, etc. to be image edited are stored in advance; and a display means 4 for displaying an image at a location corresponding to the position of the cursor C8 on the display screen 4a. , a cursor control means 5 for controlling the cursor O8 on the display screen 4a of the display means 4 based on a signal from the cursor operation section 2; The image input means 1 is provided with an image conversion operation section 9 for specifying a predetermined image conversion, and the image editing control means 6 is used to create a display image on the display screen 4a. The control means 6 includes
An image conversion control unit 10 that performs a specified conversion operation on the existing image located in front of the cursor C8 position based on a conversion designation signal from the image conversion operation unit 9.
It has been established.

"Effect" According to the technical means mentioned above, the size of the cursor, which is the image input index, changes across multiple lines, so editing such as insertion and deletion, which was previously performed line by line, is no longer possible. Actions can be performed in multiple lines at once.

In addition, when editing an image that includes image parts with different display formats, first temporarily edit the image in the standard display format, and then convert the display format of the target image part using a simple image conversion operation that does not involve cursor operations. This eliminates the need to specify the image conversion area using the cursor.

[Embodiments] Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

1-upper 1fl+λ prefecture! FIG. 2 is a block diagram of a word processor to which the present invention is applied.

In the figure, reference numeral 20 denotes a keyboard having a cursor key 2081 for operating a cursor, various function keys 20b1, alphanumeric keys 20C, various mode keys 20d for selecting an image editing mode, and a numeric keypad 20e for numerical input. , various keys from this keyboard 20 are input to the CPU 2 via the input interface 21.
2 is set to be input. And this CPU
22 executes cursor control and image editing control equipped with various functions to be described later while exchanging data with memory 23, and displays data on the display screen of CRT display 25 as display means via output interface 24. The cursor is indexed and the image is displayed and edited. Also, in this embodiment, the CRT
In order to be able to display and erase characters etc. on the display 25 at high speed, assembler is used as the language used by the CPU 22. Incidentally, reference numeral 26 is a printer for printing the image on the CRT display 25 as it is.

[2] Keyboard Configuration FIGS. 3 to 6 are explanatory diagrams showing details of the key arrangement of the keyboard 20.

First, the cursor keys 20a are of four types (→, ←, ↑, ↓), and are used to move the cursor in the respective arrow directions.

Further, the various function keys 20b are used to move an image in which a region has been set to a predetermined location, to copy the image, and to perform other functions.

Further, the alphanumeric keys 20c are as shown in FIG. 4, and special characters and codes used in mathematical formulas, chemical formulas, etc. are assigned to these existing alphanumeric keys 20c. In this embodiment, the frequently used special characters and codes are FJJ with the fRJ key, rJJ with the rlJ key, FJJ with the rlJ key,
``CJ'' can be directly assigned to keys with similar shapes such as the ``C'' key, and among special characters and codes that are rarely used, those with similar shapes are set in the same group, and keys with similar shapes are indirectly assigned to. For example, there is something like the one shown in Figure 5 (aHb), in which case the mode key described later
If you press the target F(J or "-" in combination with the GRPH key, which is one of the keys 20d, a frequently used symbol similar to "(" or "-" will be obtained first,
Furthermore, when the XFER key, which is the - mode key 20d, is operated, symbols similar to the above "(" or "=" are sequentially selected.It should be noted that the operability of the cursor is improved. Therefore, some of the alphanumeric keys = 20C (SPACE, BS, CTRL) are located in easy-to-operate positions.
+5PAGE, CR), press the cursor key (→, ←-1
↑, ↓) functions are assigned.

Furthermore, the mode key 20d, as shown in FIG.
(CTRL, 5IIIFT, INS, DEL
, TAB, CR.

XFER, NFER, GRPH) 'S Kara *'),
Single M L < 1. The cursor (noise variable setting (CTRL, S old FT
, ↑, ↓ combination t), insertion (INS), deletion (DEL)
), character 'a conversion (NFER-E) sen), etc. can be selected from various editing modes.

In addition, the numeric keypad 20e is not shown in FIG.
3, 6, and 9), and are also indirectly assigned to various displays R (displays with different line thicknesses, three-dimensional displays, etc.). In this example, mode key 2
By operating the 5HIFT key, which is one of the 0d keys, and the desired numeric keypad, the corresponding partial symbol of the benzene nucleus can be obtained, and by operating the XFER key, various display modes can be sequentially selected. It looks like this.

In particular, in this embodiment, since each partial symbol of the benzene nucleus is assigned to a position corresponding to a hexagon, it is possible to intuitively grasp the position of each partial symbol of the benzene nucleus. Furthermore, in this embodiment, the symbols of the Feynman diagram used in particle physics are also assigned to the existing numeric keypad.

In this embodiment, the memory 23 corresponds to the various keys manually assigned (including special characters and codes necessary for mathematical and chemical formulas) on the keyboard 20. characters, symbols,
It stores symbols and the like, and allows the CPU 22 to access characters and the like corresponding to keystrokes.

This memory 23 also serves as an official dictionary that readably stores images (for example, formulas, etc.) cut out by specifying an area as will be described later. It is now possible to do so.

In this example, the image input mode is:
You can select a text mode that is suitable for expressing sentences such as normal English letters, and a formula/chemical formula mode that is suitable for displaying mathematical formulas, chemical formulas, etc. In this embodiment, the mode can be switched to either mode by pressing CTRL+¥.

Now, when the mathematical formula/chemical formula mode is selected, the CPU2
2 executes 1/2 line feed mode. In this 1/2 line feed mode, as shown in Figure 7, normally lines are broken in the order of 1, 2, and 3, but lines 1' and 2' are present in between these lines, and the lines are broken in the order of 1, 2, and 3. , the cursor is set to line feed in units of 1/2 lines. In this case, since the line spacing becomes narrower, it becomes possible to display multiple superscripts and subscripts, and to display fractions naturally.

In addition, according to this 1/2 line feed mode, adjacent lines, for example, the 1st line and 1'th line in Figure 7, are half-characters (there will be an overlap, and the display screen of the CRT disk 1 and 25 will be A situation occurs where the image displayed above overlaps with the overlapping area.In this case, if the image below is completely removed, editing the image of mathematical formulas or chemical formulas becomes virtually impossible. 1) To make it possible,
In this example, if the images overlap, the EO
Display control is performed using R (exclusive OR).

In this embodiment, the cursor O8 on the display screen indicates the downward dimension of the normal unit character, as shown in FIG. However, after executing the variable length cursor creation mode, the cursor extends vertically by a predetermined amount across multiple lines. In this case, among the cursor C8 whose size extends in the vertical direction, the upper area including the area where the standard size cursor is located is colored blue (E3L), and the lower area is colored green (GR) by one color each. It has become something that has been done.

Further, the variable length cursor creation mode adopted in this embodiment follows flowchart 1 as shown in FIG. That is, when creating a variable length cursor, the CPU 22 performs the following actions: ■ Extends the cursor position by 1 x 2 lines toward the F side each time the [CT old - 10 ↑] key is available; ■ [CTRL + ↓
Every time there is 1 key force, the cursor that has extended upwards will be shortened by 1 mm and 2 lines, ■ [5HIFT + 4] key The cursor position will be extended downward by 1 mm and 2 lines every time there is force, ■[5HIFT ↑] Every time you have enough strength, the cursor that has extended downwards is shrunk by 1/2 lines, ■[5
HIFT + CR] key The cursor size will be returned to the standard size if there is human effort.

Now, move the standard size variable length cursor C8 two lines above,
The operation of the CPtJ 22 will be explained using an example in which one line is expanded to the lower side.

First, assume that a standard size variable length cursor C8 is on the current line (FIG. 10(a)).

In this state, when the [CTRL ↑] key is operated, CP (J22) does not extend the variable length cursor upward by 1 x 2 lines (Fig. 10 (b)).
I, +↑] key operation is repeated three times, and the variable length cursor C8 extends by 1 x 2 lines x 3, and the entire area moves upward by 2 lines.
It will be extended by the length of the line (Figure 10 (C)). At this time, if you press the [CTRL + ↑] key too many times, the variable length cursor C8 will extend too far upwards, as shown by the virtual line in Figure 10 (C).
] By performing an appropriate number of key operations, the overextended area can be shortened. Next, if you repeat the [5HIFT→～↓] key operation twice, the variable length cursor C8 will extend downward by 1 x 2 lines, and the whole will extend downward by 1 line. 10(d)), at this stage, the size setting of the variable length cursor C8 is completed.

Incidentally, by operating the [5HIFT +CR] key, the variable length cursor C8 that has been variably set can be returned to the standard size (FIG. 10(e)).

[4,3] Insert Spendis - E-1 This mode is one of the ways to use the variable length cursor C8. For example, as shown in Fig. This is used when inserting a space in column j or column j+1.

This space insertion mode is, for example, 70-
Follow the rules.

Now, in the example shown in FIG. 11, if the number of lines N in which spaces should be inserted is (n+1) x 1/2 lines, then
As shown in the figure, the vertical dimension of the variable length cursor C8 is set in advance in accordance with the number of lines to be inserted in the space,
Place it at the corresponding location of the 0 column to be inserted.

In this state, when the [INS] key (mode key for inserting spaces) is operated, the process shown in FIG. 12 is performed, and a row of spaces are inserted in the range corresponding to the variable length cursor C8 position. Next, when the [INS] key is operated again, the process shown in FIG. 12 is performed, and one row of spaces is inserted corresponding to the variable length cursor C8 position, resulting in variable length data in columns j and j+1. A space will be inserted in the cursor C8 range.

In addition, when deleting a rectangular area that spans multiple lines,
A deletion mode similar to the space insertion mode may be executed. In this embodiment, in the deletion mode, a variable length cursor C8 is placed at the location to be deleted, and [DE
L ] key operation erases the image information in the range corresponding to the variable length cursor C8.

4.4 Area setting/cancellation mode This mode is also one of the ways to use the variable length cursor C8, and is used to set/cancel an arbitrary rectangular area R as shown in Fig. 14.
This allows for cancellation.

In this embodiment, the area setting mode follows the flowchart shown in FIG. 15, and the area setting cancellation mode follows the flowchart shown in FIG. 16.

The area setting mode will be explained using FIG. 14 as an example.

Now, at the location marked ■ in FIG. 14, first, after setting the variable length cursor C8 to the vertical dimension h1 of the arbitrary rectangular area R, in this embodiment, the [5HIFT+→KOKI1 operation is performed.

Then, the CPU 22 moves the variable length cursor C8 to the right column according to FIG. 15, and sets the position of the variable length cursor C8 before the movement as the setting area. Therefore, by repeating the [5 HIFT 10 →] key operation until the variable length cursor C8 reaches the position of ■, the rectangular area located to the left of ■ can be set as the setting area.

Then, at the stage when the variable length cursor C8 reaches the position indicated by ■, the vertical dimension of the variable length cursor C8 is
After resetting to 2, repeat the [5HIFT+→] key operation until the variable length cursor C8 reaches ■.
The PU 22 sequentially performs the fifteenth operation, and sets the entire rectangular area located to the left of ■ as the setting area. At this stage, the area setting for the arbitrary rectangular area R is completed.

After setting the area in this way, by operating the appropriate mode key 20d or function key 20b, you can move the set arbitrary rectangular area,
It can be copied or deleted.

Further, the area setting cancellation mode will be explained using FIG. 14 as an example.

Now, after placing the variable length cursor C8 at the location shown in Figure 14 with the vertical dimension h2 set, in this embodiment, if the [5HIFT+←] key operation is repeated, the CPU 2
2, the variable length cursor C8 is moved to the left by -columns according to FIG. 16, and the setting of the area is canceled by -columns.

Then, when the variable length cursor C8 reaches ■, its length is reset to hl, and thereafter [5HIFT+
←] If you repeat the key operation, variable length cursor O8 will change to ■
The area setting of the arbitrary rectangular area R is canceled at the stage when . In addition, in this example, [CTRL+CR]
By performing a key operation, you can cancel the set areas at once.

Note that the arbitrary rectangular area in which the area setting/cancellation mode can be executed is not limited to that shown in FIG.
There is no problem even if it is more complicated as shown in FIGS. 17(a) and 17(b) with R1 and R2.

4.5] Superscript 1/4 square character conversion mode This mode is
This is used when displaying a mathematical expression such as Aa+b, and basically follows the flowchart shown in FIG.

Now, to explain the above mode based on the specific example shown in FIG. 19, first, in the standard display format (English character format),
Enter +b. At this time, the cursor C8 is positioned in the column next to the last input character.

In this state, when the [CTRL+=] key is operated, the CPU 22 operates as shown in FIG. 18, and first converts [b] into a superscript quarter-width character.

Subsequently, when the [CTRL+=] key operation is repeated twice, the CPU 22 converts these into superscript quarter-width characters in the order of [+] and [a]. Therefore, operations such as specifying the conversion area of superscript quarter-width characters with the cursor C8 are no longer necessary.

Note that in this embodiment, it is of course possible to convert - characters one by one into superscript quarter-width characters.

Furthermore, conversion of quarter-width characters with middle characters and quarter-width characters with subscripts is realized by a mode similar to the mode described above.

[4,6] Conversion mode to Greek characters, etc. This mode is used when converting the standard character format abc to Greek characters such as αβγ and displaying the result, and usually follows the flowchart shown in FIG.

Now, to explain the above mode based on the specific example shown in FIG. 21, first, ab
Enter c. At this time, the cursor C8 is positioned in the column next to the last input character.

In this state, if you operate the [NFE11] key,
The CPU 22 operates as shown in FIG.
] to the corresponding Greek letter [γ]. continue,
If you do not repeat the [NFER] key operation twice, the CPU 22 will
bl [a] These are replaced by the corresponding Greek letter [
β] can be converted to [α]. Therefore, operations such as specifying the character conversion area with the cursor C8 are no longer necessary.

In this embodiment, it is of course possible to convert the - characters one by one into Greek characters.

Furthermore, in this embodiment, characters other than Greek characters can be converted. For example, [CTRL+NFER]
It can be converted to German letters by operating the keys, it can be converted to italic letters by operating the [GRPH+ NFEJ keys,
By operating the [FT +NFER] key, it can be converted to English cursive, and by operating the [CT old -→-V] key, it can be converted to emphasized characters, which are mainly used when displaying vectors, etc. I can do it.

[4, 7] 劃ゆ叉 1 goノ URAMI 1 hair ” so l 2 lower This mode is used to resize the entered symbol vertically, and is basically shown in Figure 22. Follow the flowchart.

The vertically variable size characters that can be used in this mode are J
,f,J,c,>,(,),[,],l.

11 are mentioned.

Now, to explain the above mode based on the specific example shown in FIG.
The operation shown in FIG. 2 is performed to increase the vertical dimension of the above ffJ to twice the standard size. Subsequently, when the [XFER] key operation is repeated, CP j, J 22 increases the vertical dimension of "f" by the number of key operation ports of the 4M quasi-size.

When the key operation reaches a predetermined number of times (six times in this embodiment), the CPU 22 returns the resized "f" to the standard size.

[Effect of the invention] As explained above, claims 1, 2, 3゜5 and 7
According to the image editing method and device described in items 1 to 12, editing operations such as insertion and deletion are performed on multiple lines at once using a variable-length cursor that spans multiple lines, so that each editing operation is performed on a line-by-line basis. It is no longer necessary to do this individually, and real image editing can be realized on the display screen without interrupting the thinking process when editing mathematical formulas, chemical formulas, etc.

Further, according to the image editing method and apparatus according to claims 4, 6 to 12, when converting all or part of an image, a simple image conversion operation is performed without specifying a conversion area with a cursor. This eliminates the need to interrupt your thinking while editing mathematical formulas, chemical formulas, etc. during the operation of specifying the conversion area with the cursor, making it possible to realize real image editing on the display screen. .

Furthermore, according to the image editing method according to claim 2.3,
Since the cursor can be extended in either the up or down direction, the size of the cursor can be easily variably set without unnecessary consideration of the standard size cursor position. In particular, according to the third aspect, since the cursor position before variable setting can be easily grasped,
There is almost no concern that the input position will be misrecognized after the cursor is returned to its standard size.

Furthermore, according to the image editing device according to claim 7,
Since the 1/2 line break system is adopted, when displaying mathematical formulas, chemical formulas, etc. on the display screen, these do not become excessively long, and the actual image of the formula etc. is displayed more realistically on the display screen. It can be reproduced with.

Further, according to the image editing device according to the eighth aspect, even if the 1/2 line feed method is adopted, it is possible to effectively avoid unnecessary erasure of images on the display screen.

Further, according to the image editing device according to claim 9, special characters and symbols used in mathematical formulas and chemical formulas are assigned to existing keys, so that a list of special characters and symbols can be displayed and used with a mouse, etc. The input operation can be simplified compared to the case of selection. Furthermore, according to the image editing apparatus according to claims 10 and 11, when assigning special characters, etc. to the keys, those having a similar shape to the existing key display are selected, so that the special characters, etc. and the existing key display are selected. The keys can be visually associated with each other, and input operations for special characters can be improved accordingly. Furthermore, according to the twelfth aspect, when assigning benzene nuclei to keys, keys located at positions corresponding to the hexagonal shape are selected.
When performing an input operation for a partial symbol of a benzene nucleus, the key position can be grasped intuitively, and the operability of inputting a benzene nucleus can be improved accordingly.
