Abstract

PURPOSE:To reduce the mis-input by providing a display unit on which data is displayed and an enlargement control part which enlarges and displays a designated part of the display picture on this display unit and changing display data on the enlarged picture. CONSTITUTION:A display unit 1, a keyboard 2, a mouse 3, a processor part 4, a display control part 5, a data generation processing control part 6, and an enlargement control part 7 are provided. If display data on the display unit 1 has a part to be changed, an enlargement range including this part is designated and is enlarged and displayed. The part to be changed is enlarged in this manner to easily finely indicate the change.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display data creation device for various information display systems.

0002

2. Description of the Related Art In a display data creation device such as a personal computer, one dot as a drawing unit is divided into multiple dots on the screen, for example, 4 (2×2) dots or 16 (
4×4) dots to create graphic data such as graphic patterns.

In the above-mentioned apparatus, for example, the graphic data on the screen as shown in FIG. 4(a) is converted to
Even when changing to the graphic data as shown in , it is possible to cope with the change by performing a drawing operation in units of dots while the above-mentioned correspondence ratio of dots is fixed. Note that the example in FIG. 4 shows a case where part A is added.

0004

[Problems to be Solved by the Invention] However, with the conventional display data creation device as described above, when making small changes as shown in FIG. 4, the problem is that it is difficult to operate and input errors are likely to occur. was there.

The present invention has been made in view of these problems, and aims to provide a display data creation device that is easy to operate even when making small changes and is less prone to input errors.

[0006]

[Means for Solving the Problems] A display data creation device of the present invention includes a display unit for displaying data;
The display device includes an enlargement control section that enlarges and displays a specified portion on the display screen, and is configured to change display data on the enlarged screen.

[0007]

[Operation] In the display data creation device of the present invention, a designated portion on the display screen is displayed in an enlarged manner, and data can be changed on the enlarged screen.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing a schematic configuration of a display data creation device according to an embodiment of the present invention. In the figure, 1 is a display unit for displaying data, 2 is a keyboard for inputting display data, 3 is a mouse for specifying changes in display data and giving various control commands, and 4 is a processor equipped with memory, etc. , a display control section 5 that controls the display of the display unit 1, a data creation processing control section 6 that processes data input from the keyboard 2, etc. to create data to be displayed on the display unit 1, and a display of the display unit 1. It includes an enlargement control section 7 that enlarges and displays a specified portion on the screen, and displays data can be changed on the enlarged screen.

Next, the operation will be explained. FIG. 2 is a flowchart showing the operation when changing display data in the apparatus configured as described above.

First, in step S1, it is determined whether or not there is a change in the display data on the display unit 1.
If there is a change, an enlarged range including the changed part on the display screen is specified in step S2. At this time, as shown in FIG. 3(a), a drawing screen with an initial state of correspondence ratio is displayed in which 1 dot of the drawing corresponds to 4 (2×2) dots on the screen, and the dotted line Specify the starting point C of the part B that you want to enlarge using the mouse 3 or the like. As a result, the portion B within the dotted line is enlarged as shown in FIG.
The dots are displayed in a correspondence ratio of 64 (8×8) dots on the screen.

Next, in step S3, the portion D is changed (here, added) on the enlarged screen shown in FIG. 3(b). Then, in step S4, it is determined whether or not the change operation has been completed, and if it has been completed, the display screen is returned to its original state in step S5. At this time, as shown in FIG. 3(c), the changed portion D is also reduced to become a screen with the initial correspondence ratio.

[0012] In this way, only the part to be changed can be enlarged and drawn, so even when making small changes, the operation is simple and input errors are reduced. Also, it becomes easier to check complicated drawn parts.

Note that the present invention can be applied even when the overall size is large, that is, when the drawing area is wide. In this case, in the process of enlarging the entire image, if the original size is too large, it will not fit on the screen, but in the present invention, only a portion is enlarged, so there is no problem.

[0014]

[Effects of the Invention] As described above, according to the present invention, a specified portion on the display screen is enlarged and data can be changed on the enlarged screen. This has the effect of simplifying the process and reducing input errors.
