Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a display device that simultaneously displays a plurality of image areas on one screen and has a scroll display function, without using a scroll key. The present invention relates to a screen switching display device in which is displayed in the center of the screen by scrolling.

[Conventional technology]

Conventionally, when an image area including a plurality of target images is displayed on the screen 1 of the display device as shown in the seal stamp matching display device of FIG. 3, for example, in a seal stamp search system, a seal stamp previously registered in a file. The attribute information, the signature (image A) 2 and the seal imprint (image B) 3 are displayed and collated with those of the target document. In many cases, the image area including these two target images A and B cannot be specified because the area size and arrangement are different for each account number. Therefore, it often happens that one of the images A and B protrudes from the screen of the display device. Further, even if the image does not protrude from the screen, the arrangement may be unbalanced. Furthermore, when the display device is a CRT, the image is distorted if the image is at the edge, and accurate confirmation cannot be performed. In particular, when performing a collation of a seal stamp, a distorted image may result in a mistaken confirmation of a stamp that has been used improperly as a genuine seal stamp. , It is necessary to confirm with an accurate image. Therefore, the image is moved by using the scroll-required method. In this scroll-necessary system, the entire screen is moved up and down and left and right by a manual operation using the illustrated scroll key 4. First, the optimum position for matching the image A is selected, and then the image B is selected.
It is operated to select the most suitable position for the collation.

[Problems to be solved by the invention]

The optimum position on the screen of such a conventional seal matching display device is the center of the normal screen. A scroll key is used to move the image A2 and the image B3 to the center. However, the operation is not so easy and takes time, and the configuration related to the scroll key is considerably complicated. This is because the feature of the scroll key is configured so that it can be freely moved to any position.

On the other hand, in the case of the present invention, since the plurality of image areas are predetermined and the position to be moved is the center of the screen of the display device, attention is paid to the fact that there is no need to operate the scroll key. High-speed operation is possible because the movement is performed all at once with the switching key.

An object of the present invention is to provide a screen switching display device in which a screen of a display device is moved at once by a switching key without using a scroll key so that a desired image region is scroll-displayed at the screen center of the display device. Especially.

[Means for solving problems]

In order to achieve the above object, the screen switching display device of the present invention includes a file (11) in which a plurality of image regions to be displayed simultaneously or separately on the display screen of the display device are registered in advance, and each of the separate image regions. A means (14) for storing attribute information and an address corresponding to, and a screen memory (10) sufficiently large in the periphery of a storage surface corresponding to a display screen for temporarily storing the image area data read from the file by the address. Further, a screen switching key (16) for sequentially switching from the simultaneous display screen of the plurality of image areas to each separate display screen, and the screen memory by the address from the address storage means sequentially according to the pressing time of the screen switching key A control means (15) for setting the display range by directly moving the display center of the image area of each of the separate displays read out to the screen center of the display device is provided, and each time the screen switching key is pressed The screen is switched from the simultaneous display screen of a plurality of image areas so that the display center of each of the plurality of image areas becomes the screen center of the display device.

[Action]

If you press the screen switching key once, for example, images A and B
Is scrolled from the screen having "" to the screen centering on image A. Next, when the button is pressed once again, the screen is switched to a scroll display centered on the image B. Further pressing returns to the screen with the first image A, B. In this way, the screens are switched at once by a simple operation of the switching key without using the scroll key.

〔Example〕

FIG. 1 is a configuration explanatory view of an embodiment of the present invention, and FIG.
(a)-(d) is operation | movement explanatory drawing.

In FIG. 1, for example, in a seal retrieval system,
An image area including a signature including a name and an address as the attribute information and the image A, and an image area including a seal imprint as the image B are registered in the file 11, and the file contents are read by the account number from the keyboard 13 via the controller 12. Read. Then, the attribute information once stored in the register 14 and the address signals of the image A area and the image B area are sent to the screen memory (VRAM) 10 to store the corresponding image memory. The VRAM10 prepares a second as shown in Figure (a), the logical window address space of the relative physical screen 1 ₁ quadrant buried other quadrants 1 _{2-1 4.}

In the case of FIG. 9A, since both images A2 and B3 are displayed at the normal positions on the physical screen, the collation search can be performed as it is, but in the case of FIG. , image B3 'both protrudes from the physical screen 1 _1. Furthermore, when a CRT is used as a display device,
The edge of the screen has large distortion and cannot be used as a reference for matching and searching. Then, by switching the switch key, image A
2'and the image B3 'are arranged at the centers of the physical screens 1'to obtain the screens shown in FIGS.

Returning to FIG. 1, in order to realize the principle of FIG. 2 (b),
The coordinates of the predetermined image area of the contents of the register 14,
The VRAM 10 is sent to the center display control circuit 15, and the VRAM 10 is controlled so that the predetermined image area is set to the screen center of the display device. The screen switching key 16 is used to switch the predetermined image area. It is assumed that both the image A2 'and the image B3' are displayed as shown before the screen switching key 16 is pressed.
Image B (mark) 3'when the first switch key 16 is pressed
The area coordinates are entered in the center display control circuit 15, and the movement equivalent to the scroll display is performed all at once so that the center of the coordinates becomes the center of the screen. This is referred to as scroll display without using scroll keys. When the next switching key 16 is pressed, the attribute information and the image A (signature) 2'are similarly moved in the center of the screen without using the scroll key, which is equivalent to the scroll display. When the switching key 16 is further pressed, the display of both images A and B is returned to the initial display.

〔The invention's effect〕

As described above, according to the present invention, the screen switching key is provided, and each time the user presses the screen switching key, the center of each of the plurality of image regions becomes the screen center in sequence. The screen is switched by performing a movement equivalent to the scroll display. As a result, the operator simply presses the screen switching keys in sequence, and easily obtains a desired image area scroll-displayed with the screen center, without using scroll keys that are difficult to operate. In particular, in a seal stamp search system or the like, by scroll-displaying an image in the center of the screen, a distortion-free seal imprint can be obtained, so that accurate matching can be performed. Further, when the display device is a CRT, the image is distorted when the image is at the edge. Therefore, if the image is displayed at the center of the screen, the image is distorted and accurate confirmation can be performed.
