Abstract

PURPOSE:To improve the efficiency of inputting and editing work by enlarging and displaying text data on an auxiliary screen and dimultaneously coloring a cursor with a prescribed color corresponding to an operation command for inputting and editing. CONSTITUTION:A text data display device is formed of a display list buffer 6, a display professor 7, a graphic processor 8, a text generation processing system 10, a magnified screen text generation processing system 11, a cursor pattern generation processing system 12, a frame buffer 13, a display controller 14, a color look-up table 15 or the like. The cursor is displayed within a screen where the text data is displayed and placed at a position or in an area which should be inputted and editted. Besides, the text data is enlarged and displayed on the auxiliary screen and the concerned cursor is colored with the prescribed color according to the operation command for inputting and editing at the same time. Thus, since inputting and editing can be executed within the magnified auxiliary screen while watching the whole screen, eyesight is prevented from failing necessarily caused by the inputting and editing work.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for inputting and editing text data, and
The present invention relates to a text data display device.

More specifically, the present invention relates to inputting and editing text data such as sentences and programs using a computer,
The present invention also relates to an input/editing method and a display device that can be used to improve the working efficiency of inputting/editing text data on a screen in a CAD or the like.

Summary of the Invention 1 The present invention relates to a text data input/editing method and a text data display device.

According to the present invention, in order to reduce the labor of inputting and editing text data performed by a computer operator,
The line being input/edited can be enlarged to make it easier for the computer operator to see. Further, by incorporating color information into the operation command for input/editing work and coloring the cursor in a predetermined color, the computer operator can easily understand and confirm the information.

[Prior Art 1] Currently, many text data input/edit screens used in computers such as engineering workstations are as shown in FIG.

In Figure 2, the line where input/editing is being performed is the line where a square mark called the cursor (2-3) appears, and as you can see from Figure 2, the font is the same as the previous and following lines. For computer operators, inputting and editing work while looking at fine print is difficult work that can lead to poor eyesight.

In addition, input/editing work is performed after specifying and inputting an operation command such as inserting a character at the position of the cursor (2-3) or deleting a character at that position, but which operation command was specified? There is also a method of displaying it separately on the margin of the text data screen (2-2), but it is inconvenient as it requires the line of sight to be directed there, so some kind of improvement is needed. .

[Problem to be Solved by the Invention 1] Therefore, an object of the present invention is to improve the ability of a computer to input and edit text data such as sentences and programs using a computer, and to input and edit text data on a screen in CAD, etc. - To provide operators with an input/editing method and a text data display device with high work efficiency and a good work environment.

[Means for Solving the Problems 1] The text data input/editing method according to the present invention displays a cursor within a screen on which text data is displayed, and positions the cursor at a position or area to be input/edited. The text data included in the position or area is enlarged and displayed on the auxiliary screen, and the cursor is colored in a predetermined color in response to an input/edit operation command.

Further, the text data display device according to the present invention includes a display means for displaying input text data and a movable cursor, and a coloring means for coloring the cursor in a predetermined color in response to an input/edit operation command. and an enlargement means for enlarging and displaying the text data designated by the cursor on an auxiliary screen.

[Function 1 When inputting or editing text data such as sentences or programs, the computer operator focuses on the line on the monitor screen where the cursor is located, and the line before and after it. Rows are generally referenced during work.

Therefore, in the present invention, as shown in FIG.
-2 Since it is possible to input and edit on the enlarged auxiliary screen 3-4 while looking at the entirety of the screen, it is possible to prevent visual acuity deterioration that is often associated with inputting and editing operations while looking at small, large characters.

In addition, the cursor 3-3 that indicates the input/edit work position can be colored to associate input/edit operation commands, so it is obvious at a glance which operation command has been specified, and it is easy to remember and use. There is no need to separately look at the display outside the margin of the text data screen 3-2.

[Example] Hereinafter, one embodiment of the present invention will be described in detail.

FIG. 1 is a block diagram showing the overall configuration of a display device to which the present invention is applied. In the figure, 1 is a ROM;
Stores computer startup processing programs, etc.

Next, the input/edit procedure according to this practical example will be explained with reference to FIGS. 3 and 4.

l) First, go to the text screen 3-2, move the cursor 3-5 to the position you want to input/edit, and press <(') Step S.
2. S4).

2) When specifying and inputting operation commands such as inserting characters and deleting 8 characters (step S6), the enlarged support screen 3-
4 will appear (step S8), and the computer operator will input and edit within that screen. At the same time, the lines before and after that can also be referenced and confirmed on the text screen 3-2.

3) The cursor 3-3 appearing on this enlarged auxiliary screen 3-4 is colored according to the operation command, so the current input/edit mode can be understood and confirmed (Step 5IO) .

For example, insert mode may be red and delete mode may be blue.

4) Finish inputting/editing the line (step S12.
S14. When the confirm key is pressed (step S16) (step 318), the text in the enlarged auxiliary screen 3-4 returns to the corresponding line on the original text screen 3-2.

5) Repeat steps 4) to 4) above.

As described above, since the input/editing work can be performed on an enlarged screen, it is expected that the visual fatigue of the operator will be reduced and the efficiency of the input/editing work will be improved. In addition, by using a cursor that incorporates color information into the operation command, it is possible to easily understand and confirm input and editing operations at that point without moving your eyes, which is expected to similarly improve the efficiency of input and editing work. .

Effects of the Invention] As explained above, the present invention is applicable not only to inputting and editing text data such as sentences and programs using a computer, but also to inputting and editing text data on a screen in CAD, etc. This not only improves the work efficiency but also improves the work environment.
