Abstract

PURPOSE:To realize the divisional scrolling system which is simple in operation by dividing a physical screen only by indicating one or two points on the physical screen. CONSTITUTION:An area in the physical screen 100 to be stopped from being scrolled and held on the physical screen is specified by specifying its diagonal points 131 and 132 and this is a scroll fixed area 140. Then even when the physical screen is moved on a logical screen by a longitudinal scrolling means 110 and a lateral scrolling means 120, the display in the scroll fixed area 140 does not change. A means which divides the screen into plural areas divides the physical image plane into plural areas by specifying one or two points on the physical screen and the positions on the logical screen that the respective areas correspond to are stored. Consequently, part of the physical screen can be set as the scroll fixed area and areas which are distance on the logical screen can be displayed on the same physical screen at the same time.

[Conventional technology]

The first example of this kind of conventional scrolling method is, for example, as typified by Japanese Patent Application Laid-open No. 13281/1981.
This method was limited to specific uses such as using a part of the screen as a fixed area to display information on an application program, or inputting text as typified by Japanese Patent Laid-Open No. 59-206886. A second example of this type of conventional scrolling method is a so-called multi-window method in which a plurality of physical screens are provided on the same logical screen and each is treated separately.

[Problem to be solved by the invention]

The above-mentioned conventional technology is not versatile because it is dedicated to a specific application program or is a method that takes only a specific purpose into consideration, or requires many operations to open another physical screen, making the screen complicated. There were some problems.

An object of the present invention is to realize a divided scrolling method that is easy to operate and has high versatility.

[Means to solve the problem]

In order to achieve the above object, the present invention includes means for dividing a screen into a plurality of areas with a simple operation, and means for independently changing the position of each area on the logical screen.

C action] The means for dividing the screen into multiple areas is to divide the physical screen into multiple areas by specifying - or two points on the physical screen, and memorize the position of the logical screen to which each area corresponds. . The means for independently changing the position of each area on the logical screen selectively gives each area an instruction to move the physical screen on the logical screen. . In this way, it is possible to make a part of the physical screen a scroll fixed area, or to display separate areas on the logical screen simultaneously on the same physical screen.

〔Example〕

FIG. 1 is an example of a screen display of the first embodiment of the present invention.
00 is a physical screen, 110 is a vertical scrolling means, 120 is a horizontal scrolling means, 131 and 132 are diagonal points of a scroll fixed area, and 140 is a scroll fixed area.

The operation of this embodiment will be explained below. User is on physical screen 1
In 00, specify [31.132] the diagonal point of the area where you want to fix scrolling and keep it on the physical screen. The designated area then becomes the scroll fixed area 140. Thereafter, even if the physical screen is moved on the logical screen by the vertical scrolling means 110 or the horizontal scrolling means 120, the display within the scroll fixed area 140 does not change.

FIG. 2 is a diagram showing the relationship among the logical screen, physical screen, and scroll fixed screen in this embodiment, and 200 is the logical screen.

Here, the origin of the logical screen 200 is the top left corner, the X coordinate is on the right, and the Y coordinate is on the bottom. Also, physical screen 10

Thereafter, the physical screen 611 divided into one line can be displayed by freely scrolling the portion above the divided line using the corresponding vertical scrolling means 621. Similarly, the line-divided physical screen 612 can be displayed by freely scrolling the portion below the divided line using the corresponding vertical scrolling means 622. Horizontal scrolling by the horizontal scrolling means 120 affects both physical screens in the same way.

In the case of horizontal division, the same is true; the user specifies the column on the physical screen 100 that he wishes to divide horizontally using the column division instruction point 630. Then, the physical screen 100 is divided to the left and right with the designated column as the boundary, resulting in physical screens 641 and 642 divided into 91 columns. At the same time, the horizontal scrolling means 120 is also divided left and right in the same column, resulting in horizontal scrolling means 651 and 652 corresponding to the column-divided physical screens 641 and 642, respectively. Thereafter, the column-divided physical screen 641 can be displayed by freely scrolling the portion to the left of the divided columns using the corresponding horizontal scrolling means 651. Similarly, the column-divided physical screen 612 also has a corresponding horizontal scrolling means 65.
It is possible to freely scroll and display the part to the right of the column divided by 2.

The vertical scrolling by the vertical scrolling means 110 is as follows:
