Abstract

PURPOSE:To shorten an arithmetic time and speed up scrolling operation by specifying an optional image on a screen as a basic point image, and erasing images other than the basic point image and scrolling the image. CONSTITUTION:When a request for scrolling is inputted on a keyboard 4 and the image as a basic point is specified, an arithmetic processing part 11 erases the images except the specified image and updates data in an image memory. Then the processing part 11 shifts the specified display image in display position on a CRT 2 by following up the input from a touch panel 3 for instructing the movement of the image and when an end request is inputted on the keyboard 4, the processing part 11 restores a display picture based on the position of the current specified image as the basic point, stores the image memory 16 with information on the restored picture, and scrolls the display area on the display screen of the CRT while optionally specifying the display area. During this period, only the basic point image is displayed, so the amount of information processed for the movement of the image decreases.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a scrolling method in a display system in which a partial area of image information is displayed on a display screen, and the display area can be changed and moved. and an image display device.

[Conventional technology]

BACKGROUND ART Conventionally, in order to control and manage plants and equipment, system diagrams and maps of equipment have been stored as image information in the memory of a computer, and used by displaying them on a display device as needed. In such cases, the range of information that is displayed at one time on the display screen of the display device is usually only a small portion of the stored information, and the displayed image may be moved (scrolled) within the display screen. The required information is displayed on the screen.

(a) For example, in the conventional device described in Japanese Patent Application Laid-Open No. 61-269194, it is possible to store power, gas, etc. system diagram data and street map data in separate memories, synthesize them, and display them. , it is possible to delete the street map and display only the system diagram.

(b) Also, in Japanese Patent Application No. 145732/1983, a partial area of registered graphic information is displayed on a display screen,
When scrolling the screen in a display method that allows the display area to be changed, the information displayed on the screen may be temporarily erased.

Techniques for performing scrolling and increasing the scrolling speed have been disclosed.

(c) Furthermore, in the method of displaying screen images in an overlapping manner by providing a memory for storing a background image and a memory for storing a moving image, when moving, the background image remains as is, and only the moving image is erased and displayed in a new position. There are also known methods.

[Problem to be solved by the invention]

In the prior art (a) above, when there is a lot of screen information when moving the displayed image including the background screen, there are problems such as the scrolling speed is slow and the image being moved is complicated and difficult to see.

Further, in the conventional technique (c) above, movement of the screen is not taken into account.

Furthermore, the prior art (b) above does not display the entire moving screen, and is therefore not suitable for work that requires moving the screen without checking what will be displayed on the entire display screen.

The first object of the present invention is to speed up the movement of the screen when scrolling, and to easily estimate the display area of image data after the movement when the screen is moved, so that it is possible to check what will be displayed on the entire display screen. The goal is to make it easy to do.

A second object of the present invention is to make it easier to confirm the position of an image on a display screen during scrolling.

[Means to solve the problem]

The first problem mentioned above is that when scrolling the displayed image,
Specify the image that will be the base point of the scroll as the base image,
By temporarily erasing images other than the specified image (hereinafter referred to as the base image) from the display screen and scrolling, and after scrolling is completed, restoring and displaying the erased images using the base image on the display screen as a base point. achieved.

The first problem described above is also solved by specifying the image that is the base point of the scroll as the base image when scrolling the displayed image, and then scrolling after once simplifying the display of images other than the base image, and then scrolling. This can also be achieved by restoring and displaying the simplified image on the display screen as before after the completion.

The second problem mentioned above is that when scrolling the displayed image,
Specify the image that will be the base point of the scroll as the base image,
This is achieved by displaying the base point image in an emphasized manner relative to other images, scrolling, and restoring and displaying the highlighted image on the display screen as before after scrolling is completed. Ru.

The second problem described above is also that when scrolling display images, an image that is the base point of scrolling is specified as the base image, and images other than the base image are displayed so as not to be noticeable with respect to the base image. This can also be achieved by scrolling after scrolling, and restoring and displaying the inconspicuously displayed image on the display screen as before after the scroll is completed.

In the above method, the display image when moving the screen may be displayed at the position after the movement ends, rather than at the position where the screen is being moved, even if the image is moved while being displayed on the screen. .

[Effect]

While scrolling, only the base image is visible, reducing the amount of information processed to move the image.
Since less calculation time is required, scrolling becomes faster. Even when parts other than the base image are displayed in abbreviated form during scrolling, the amount of information processed to move the image is similarly reduced, and the required calculation time is shortened, making scrolling faster. be done.

Furthermore, if only the base image portion is displayed while scrolling, it becomes easier to confirm the scrolling state. In some cases, image parts other than the base image are displayed in a simplified manner, the base image is highlighted relative to other image parts, or other image parts are displayed inconspicuously relative to the base image. Similarly, it becomes easy to check the scrolling status.
