Abstract

PURPOSE:To improve the operation efficiency of a user by moving information which is displayed at the border part of plural pictures to easy-to-see positions. CONSTITUTION:A display control means 4 detects the user trying to access information at the border part of plural pictures according to information from a position coordinate input means 6 and the contents of a display coordinate display means 5 are altered by the display control means 4 to easily move the picture displayed on a display device 3a by an image signal generating means 2, so that the information displayed at the border part moves to an easy-to-see position.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display control device used in a computer capable of displaying image information in addition to text.

0002

[Conventional example] Recently, display control devices have been actively used in the field of graphic user interfaces, which are technologies that make it easier to use by visually appealing to users, such as user interfaces for circuit design support systems. It's starting to happen.

A conventional display control device will be described below with reference to FIG. FIG. 2 shows a configuration diagram of a conventional display control device. In FIG. 2, 1 is an image information storage means for accumulating image information to be displayed on a display device, 2a and 2
3a and 3b input image signals and display them as images; It is a display device. Here, the same thing can be said even if there are two or more image signal generation means and display devices.

The operation of the above configuration will be explained below. First, the image information storage means 1 has a storage capacity sufficient to accommodate two display devices. The image signal generation means 2a converts the image information from the first address to the middle of the image information storage means 1 into an image signal and outputs the image signal. The display device 3a receives the image signal generated by the image signal generation means 2a and displays it as an image. Similarly, the image signal generation means 2b converts the image information from the center of the image information storage means 1 to the final address into an image signal and outputs the image signal. The display device 3b receives the image signal generated by the image signal generating means 2b and displays it as an image. When arranged vertically in this way with the display device 3a at the top and the display device 3b at the bottom, the image stored in the image information storage means 1 is divided into two and displayed.

[0005]

[Problems to be Solved by the Invention] However, in the above configuration, the image displayed on each display device is a part of the image drawn on the image information storage means, and the image displayed on each display device is a part of the image drawn on the image information storage means. The problem was that the images were very difficult to see.

The present invention solves the above-mentioned problems of the prior art, and aims to provide a display control device that improves work efficiency by making it easier to see the boundary portions of images across multiple display devices. .

[0007]

[Means for Solving the Problems] A display control device of the present invention includes one image information storage means for accumulating image information to be displayed on at least two or more display devices; at least two or more display coordinate storage means for storing coordinates indicating which part of the image information stored in the storage means is to be displayed on the display device; at least two or more image signal generation means for outputting image information specified by the display coordinate storage means corresponding to the display device among the accumulated image information to each display device; a position information input means; and the position information input means. The present invention is characterized by comprising display management means for controlling at least two or more of the display coordinate storage means based on information from the information input means.

[0008]

According to the above-described structure, the image signal generating means converts a portion of the image information stored in the image information storage means, which is indicated by the display coordinate position stored in the display coordinate storage means, into an image signal. In other words, the image displayed on the display device can be easily moved by changing the contents of the display coordinate storage means. The display management means determines whether the user is attempting to access a boundary portion of a plurality of screens based on input from the position information input means. According to the judgment, the display management means changes the contents of the display coordinate storage means so that the image information displayed on the boundary of the plurality of screens is brought to the center of the display device.

[0009]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a display control device according to an embodiment of the present invention. In FIG. 1, 1 is an image information storage means, 2a and 2b are image signal generation means, 3a and 3b are display devices, 4 is a display management means, 5a and 5b are display coordinate storage means, and 6 is a position information input means. . Although the case where there are two sets of image signal generation means, display device, and display coordinate storage means is taken as an example here, the same effect can be obtained with three or more sets. Also, it is assumed that they are arranged vertically with the display device 3a on the top and the display device 3b on the bottom, but this also applies if they are arranged horizontally so that the display device 3a is on the left and the display device 3b is on the right. I can say that.

First, consider the case where a location that is not a boundary is designated by the position information input means 6 as shown in FIG. 3(a). In this case, the image information 10 is located at the boundary and is difficult to see.

When the user accesses the boundary between the plurality of display devices on the display device 3a using the position information input means 6, the display management means 4 refers to the information from the position information input means 6, and the user accesses the boundary between the plurality of display devices on the display device 3a. Detects that an attempt is made to access a boundary part of an image that spans.

Next, the display management means 4 changes the contents of the corresponding display coordinate storage means 5a so that the image to be accessed is placed in the center of the display device 3a. The image signal generation means 2a converts the information in the image information storage means 1 into an image signal according to the changed display coordinate information and outputs the image signal to the display device 3a. As a result, as shown in FIG. 3(b), the image displayed on the display device 3a is scrolled upward, and the image that the user is trying to access is brought to the center of the screen of the display device 3a.

As described above, according to this embodiment, it is possible to make information across a plurality of display devices 3a and 3b easier to view, thereby improving work efficiency and having a large effect.

[0015]

As described above, the present invention can make it easier to view information across a plurality of display devices, thereby improving work efficiency and having great effects.
