Description

DETAILED DESCRIPTION OF THE INVENTION (Field to which the invention pertains) The present invention relates to a text editing method in a character display device such as a character graphic display device or a word processor device, and particularly in a device that can display characters at any position on the screen. be.

(Prior Art) Conventional character display devices include an editing device (hereinafter abbreviated as WP) for creating and correcting text, and a graphic display device (hereinafter abbreviated as GP) that displays explanatory text at the same time as figures. .)
It can be broadly classified into.

In wp, text is the target, so characters of multiple sizes are rarely displayed together, and all characters are managed as one character string, and characters cannot be deleted/inserted under this condition. It has been carefully considered to allow for efficient editing. On the other hand, since the purpose of GP is to display characters of multiple sizes in arbitrary positions, when editing sentences, emphasis is placed on the display position of each character, and by deleting/inserting characters, the display position of other characters can be changed. Moving is not considered.

Figure 1(a) shows the editing method in conventional wp, Figure 1(b)
) shows a comparison of the editing methods used in conventional GP. From the text in the diagram 5-
Indicates the case where 1 is deleted from the character ” to create the sentence shown on the left, (b
), among the characters of multiple sizes, delete “ once in the smaller character string shown on the left and enter 1ν to make the character string shown on the right without moving the display device of other characters. An example is shown below.

FIG. 2 is a diagram showing an example of character display that cannot be adequately addressed by the conventional editing method, and FIG. 3 is an example illustrating a problem that occurs when the conventional editing method is applied.

In recent years, as the resolution of graphic display devices (GPs) has improved in particular, there has been an increasing demand for GPs to display not only simple characters but also simple sentences. In other words, even in the situation shown in Figure 2, where characters of multiple sizes are displayed at arbitrary positions,
For example, a new character X is added between f and g in the string efgh.
There is a need for an editing method that allows the insertion of . However,
In the editing method conventionally used in GP, it is not possible to replace each character with the original character without changing the position where it is displayed.
When changing to , there was a drawback that the operability became extremely poor. Even if the editing method conventionally used in wp is applied to this case, as shown in Figure 3, other character strings BCD
This is not a good editing method as it results in disrupting the order of the images.

” (Objective of the Invention) The present invention has been made to solve the above-mentioned conventional difficulties, and is to provide an easy-to-operate text editing method in a display device in which characters of multiple sizes are displayed at arbitrary positions. The purpose is to provide a method.

(Structure and operation of the invention) FIG. 4 shows an example of character string division based on the present invention.
This will be explained using the document example shown in the figure.

The characters displayed in FIG. 4 are exactly the same as those in FIG. 2, and characters of different sizes and directions are displayed at arbitrary positions. In the present invention, this is divided into four sets of character strings A, 口, C, and 2 of the same size that are continuously displayed in the same direction on the same straight line, and among these sets ( More precisely, the editing method in wp is applied (targeting only areas where characters of other groups are not displayed). This makes it possible to solve the drawbacks seen in FIG.

FIG. 5 is a block diagram showing the configuration of an embodiment according to the method of the present invention, in which 1 is a shape memory section that stores characters to be displayed, their positions, sizes, and directions, and 2 is the content of the shape memory section 1. 3 is a display device; 4 is a character string extraction unit that identifies a character string that is adjacent to the designated character and has the same size and direction; 5 is a shape memory An editing processing section 6 changes the character display position stored in the section 1, an editing instruction signal 7 for insertion/deletion etc. instructed from the outside, and a character string extraction section 4
8 is a signal for notifying the character string extraction unit 4 from the outside of the character display position to be edited.・Here, in an externally provided input unit (not shown), for example, use a display means such as a cursor to specify one character from among the characters displayed on the screen, and also perform editing such as insertion or deletion. When the contents are specified, the characters to be edited and the editing contents are notified as the signal 8 and the editing instruction signal 7. First, the character string extraction section 4 selects the characters to be edited while referring to the contents of the shape memory section 1. Extracts character strings that are adjacent to, have the same size, and have the same direction.

FIG. 6 is an explanatory diagram showing an example of priorities in the character string direction, where 9 indicates the display direction, 10 indicates the first priority direction, and 11 indicates the second priority direction.

, this is to select a character string when multiple character strings are extracted.Here, the first priority character string direction 10 is 90 degrees clockwise with respect to the display direction 9, and then 180 degrees One is extracted according to a predetermined priority, such as the second priority character string direction 11.

Next, the movement instruction section 6 calculates the direction in which the characters in this character string are sequentially moved one by one based on the contents of the editing instruction signal 7 and the character string direction given by the character string extraction section 4. Subsequently, the editing processing unit 5 uses the shape memory unit 1 to move the characters in the character string obtained in this way one by one.
Rewrite the contents inside. The operation in the editing processing section 5 is executed until all the characters in the character string extracted by the character string extraction section 4 move or until the end of the screen is reached.

FIGS. 7 and 8 illustrate the editing method using the above operations using "insertion" as an example. Note that 12 in the figure indicates a cursor.

FIG. 9 shows an example in which moving processing is canceled in editing processing that performs "insertion."

In the present invention, simultaneously with the movement processing in the editing processing section 5, the editing processing section determines whether or not characters previously located at the movement destination are included in the character string extracted by the character string extraction section 4. , and the movement process is stopped even when it is determined that the character is a character other than the extracted character string.

FIG. 10 shows an example of editing in the case of "deletion", which is executed in exactly the same process as in the case of "insertion".

In the above description, the movement direction notified to the editing processing unit 5 is calculated by the movement instruction unit 6 based on the editing content given from the outside and the signal from the character string extraction unit 4.
However, it is also possible to directly notify the editing processing unit 5 of the moving direction itself from the outside.

(Effects) As explained above, the text editing method of the present invention macroscopically changes the display position, which is particularly important in graphic display devices, by regarding four columns having the same attribute as one set. There is an advantage in that it is possible to provide a highly operable character editing method that focuses on the order of character strings within a series of character strings without microscopically changing the order of the character strings.
