Abstract

PURPOSE:To improve the visibility by displaying an enlarged state of information at need in addition to a normal display when the information is displayed. CONSTITUTION:When the information is inputted from a keyboard or CPU 1, an image memory 3 is stored with pieces of display information of two kinds of size. At a position indicated by a cursor, a display of small size is made and at a position indicated by the cursor, a window 12 of previously specified size is opened to enlarge and display information on large size wherein. After the input operation, the window is closed and the original image plane is displayed. The cursor is moved to the displayed information and specific display information is specified, and an enlarged display is selected. Then the window 12 of previously specified size is cut and the specified information is enlarged to the large size and displayed. Consequently, the visibility is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) This invention relates to a display control device that improves visibility in workstations, word processors, and the like.

(Prior Art) In conventional workstations, word processors, etc., a cursor indicates where characters or the like on the display are to be displayed manually, and information output from the keyboard or CPU is displayed at the cursor position. Was.

In addition, there are cases where workstations, word processors, etc. perform high-density display or reduced display, in which case the displayed characters become smaller or reduced, resulting in poor visibility.

(Problem to be Solved by the Invention) As mentioned above, in conventional workstations, word processors, etc., when high-density display or reduced display is performed, the characters become smaller or reduced if displayed as is. There was a problem that visibility deteriorated.

The present invention has been made to solve the above-mentioned conventional problems, and when displaying characters or figures on workstations, word processors, etc., in addition to displaying them in a predetermined place as in the past, An object of the present invention is to provide a display control device that can improve visibility by automatically opening another window at a location where characters or figures of enlarged size are displayed.

[Structure of the Invention] (Means for Solving the Problems) A display control device of the present invention that achieves the conventional object described above includes a display unit that displays characters or figures, and at least two types of large and small sizes displayed on the display unit. storage means for storing display information of the smaller size stored in the storage means, displaying the display information of the smaller size stored in the storage means on the display, and displaying the display information of the larger size overlapping the display information of the smaller size. It is characterized by comprising a control section that selectively displays display information.

(Function) In the present invention, when information is input from the keyboard or the CPU, display information of two sizes, large and small, is stored in the storage means, and the display information is sequentially displayed in the smaller size at the position indicated by the cursor. , a window of a predetermined size is opened at the position indicated by the cursor, and information is enlarged and displayed in the larger size window.

When the input is completed, the enlarged window closes and the original screen returns.

Also, if you move the cursor to the displayed information, specify the specified display information, and select enlarged display, the window of the specified size will be cut off and the specified information will be enlarged to the larger size and displayed. do.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a block diagram of a workstation to which the present invention is applied.

In the figure, 1 is a CPU that performs data processing and input/output control, 2 is a memory that stores programs, etc., 3 is an image memory that stores display information to be displayed, 4 is a keyboard for inputting characters, etc., and 5 is a CR that displays character information, etc. input from the keyboard 4 and output from the CPU
6 is a display control unit that controls the display 5;

As shown in FIG. 2, the image memory 3 includes a window 11 as an area for storing characters when displaying a normal size, and a window 12 as an area storing characters when displaying an enlarged size. is provided. The windows 11 and 12 in the image memory 3 are displayed on the display 5 in an overlapping manner.

Further, in the memory 2 or the image memory 3, character fonts of two sizes, large and small, to be displayed on the display 5 are prepared in advance. - A small-sized character font for numerical display and a large-sized font for enlarged display. Note that the size of the character font is not limited to two types, and may be larger than that. In this embodiment, the memory 2 and the image memory 3 may be provided separately, or may be configured by a single memory.

Next, the operation of this embodiment configured as described above will be explained with reference to FIG.

Here, rA is displayed on the display 5 as shown in FIG. 3(A).
The case where BcJ is displayed will be explained.

Conventionally, when rABcJ is typed from the keyboard 4, the characters are manually input one after another, and rABcJ is displayed at the location indicated by the cursor on the display 5.

In this embodiment, when a key is pressed from the keyboard 4, the display characters rABCJ consisting of a small-sized font are stored in the window 11 of the image memory 3, as shown in FIG. stores display characters rABcJ consisting of an enlarged character font. The storage of this character is managed and controlled by the CPU 1 for each window 11, 12.

Window 1 of image memory 3 is displayed on display 5.
1 is opened, and window 1 is superimposed on that window 11.
Two can be opened at the same time.

As a result, the character rABcJ is displayed on the display 5 in a character font enlarged by the window 12, as shown in FIG. 3(B). In this state, as shown in Figure 3 (C
), the window 11 below the window 12 has the same characters rABc in a normal size font.
J is displayed.

When the character input is completed, the window 12 is closed, and the characters in the normal size on the window 11 are displayed on the display 5 as shown in FIG. 3(A).

In addition, if it is difficult to decipher characters due to the insufficient number of dots on the screen in a reduced display, etc., use the cursor to indicate the location on the display 5 that you want to decipher and select enlarged display, and the window 12 will open at the specified location. The information (characters) at the position indicated by the cursor is enlarged and displayed in the window 12. Selection of enlarged display is performed manually using keys on the keyboard 4.

With the display control described above, enlarged display is simultaneously performed when display information is input, so even if high-density display or reduced display is performed, visibility will not be impaired.

Although the example is shown in which characters are displayed manually from the keyboard 4, characters output from the CPU may also be displayed in the same way.

Further, although the above embodiments have been explained by taking the case of displaying characters as an example, it goes without saying that the present invention can be applied not only to displaying characters but also to displaying figures.

[Effects of the Invention] As explained above, according to the display control device of the present invention, when displaying information, in addition to the normal display, an enlarged state is displayed as necessary. Visibility is not impaired even in reduced display or high-density display of a word processor, and operability is improved.
