Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides editing (correction, deletion, addition) of character display in a soft copy display device that displays character data using a character display device such as a color cathode ray tube.
This relates to an editing method for a character display device that facilitates operations, and in particular targets character strings that have already been input and is stored in memory.
The present invention relates to an editing method for a character display device that uses color display to specify ranges and correction details when making corrections such as deletion or copying.

Character display devices are often used as terminal devices for data processing devices because they can display text copies.

In this case, the above-mentioned character display device includes:
A cursor display function is provided to display the position for editing (correcting, deleting, adding) character data.

However, the above-described cursor display function causes the following inconvenience.

(1) When specifying an entire string consisting of multiple consecutive characters, use two cursors to display the cursor at the beginning and end of the string as shown in Figure 1. (2) In editing work, multiple types of processing such as deletion, modification, addition, and movement are involved, or simply displaying the cursor is not enough to characterize the entire character string on the screen. It is not possible to clearly instruct even the contents, leading to erroneous operations and lowering the efficiency of processing work.

In view of the above points, the present invention has been made to solve such problems and eliminate such drawbacks.The purpose of the present invention is to display the range to be moved, deleted, copied, etc. by changing the color. An editing method for a character display device that allows specified characters or character strings to stand out on the screen in a color that corresponds to the processing content, thereby making editing work easier and more reliable. Our goal is to provide the following.

In order to achieve such an object, the present invention includes a control unit that performs various editing processes on specified characters or character strings or their backgrounds, and a central processing unit that temporarily stores retrieved data and then processes the data in the control unit. A storage device that updates and stores data according to the editing process, a cursor position storage unit that stores the cursor position for displaying the cursor used in the editing process, and a cursor position storage unit that stores the cursor position on the screen based on the contents of the cursor position storage unit. a cursor display control unit for displaying a cursor display control unit, a character pattern generation unit that generates a character pattern based on character data stored in the storage device, and a cursor display control unit that generates a character pattern based on the character data stored in the storage device; A background signal generation section that generates a color figure based on processing type data, and three types of patterns generated from the cursor display control section, the character pattern generation section, and the background signal generation section, respectively, are combined into one. It is equipped with a compositing section that forms a screen, and a color display that allows you to specify ranges and modification details when modifying, such as moving, deleting, or copying character strings that have already been input and are stored in memory. This is done by display.

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 2 is a block diagram showing an embodiment of the editing method of the character display device according to the present invention, in which 1 is a computer that performs data processing such as searching for edited data, and 2 is a block diagram of the character display device according to the present invention. A character display section 3, which is a main part of the editing system, is an interface section that interfaces between the computer 1 and the character display section 2.

The character display section 2 includes a control section 4 that performs various editing processes.

5 is a storage device that temporarily stores data retrieved by the computer 1 and then updates and stores the data according to various editing processes in the control unit 4; 6, 7, and 8 are three cursors used for each editing process; a cursor position storage section for storing cursor positions for displaying a, b, and C; 9 a cursor display control section for displaying a cursor on the screen based on the contents of the cursor position storage sections 6, 7, and 8;
0 is a character pattern generation unit that generates a character pattern based on the character data stored in the storage device 5, and 11 is a character pattern generation unit that generates a character pattern based on the data stored in the cursor position storage units 7 and 8 and the processing type data supplied from the control unit 4. 12 is a composition unit that combines three types of patterns generated from the cursor display control unit 9, character pattern generation unit 10, and background signal generation unit 11 to form one screen. 13 is a color cathode ray tube that displays the output signal of the synthesis section 12 in color as a soft copy; 14 is a keyboard for data input used during editing; and 15 is a function key for moving the cursor and specifying the type of processing. It is.

Note that the cursor a stored in the cursor position storage unit 6 described above
shall specify the insertion position, movement, or copy destination position, and the cursors b and c by the cursor position storage devices 7 and 8
Assume that the start and end positions of the string are specified.

The operation of the embodiment shown in FIG. 2 will now be explained with reference to FIG. 3.

First, the color cathode ray tube 13 displays a series of characters generated from the character pattern generation section 10 in response to the output of the storage device 5 and three cursors generated from the cursor position storage sections 6 to 8. There is.

In this state, the operator uses the function keys 15 to instruct the movement of cursors b and c.

At this time, the control unit 4 updates the data in the storage device 5 so that the start and end positions of the specified character strings are maintained, and the cursor display control unit 9 also moves the cursor on the screen to the specified position. do.

Next, the operator uses the function keys 15 to specify the processing content for that character string.

At this time, the background signal generation section 11 is connected to the cursor position storage section 7,
A graphic pattern based on the stored data of No. 8 is generated in a predetermined color based on the processing content, for example, as shown by diagonal lines in FIG.

That is, when making corrections such as moving, deleting, copying, etc., range specification and correction content specification are performed in color.

Therefore, the background portion of the designated character string is displayed in color on the display surface of the color cathode ray tube 13.

In this case, it goes without saying that by setting the character string to white and the background to black, color discoloration against the background becomes easier.

Incidentally, the dotted lines shown in FIG. 2 indicate the route when the target character string portion itself is displayed in color according to the processing contents.

In addition, in the above example, the color was not specified, but
By changing the color of the background or character string in accordance with the processing content, the content becomes clear.

For example, by displaying a move in blue, a deletion in red, and a copy in green, you can understand the processing range and content at a glance, and if necessary, you can immediately You can modify the specified range or change the processing content.

As explained above, the editing method of the character display device according to the present invention targets character strings that have already been input and is stored in memory, and moves, deletes, or
Since the range and correction contents are displayed in color when making corrections such as copying, the specified characters or strings can be highlighted on the screen in a color that corresponds to the processing contents. This has various excellent effects such as making editing work easier and more reliable.
