DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display control method for a display device that allows selection of an area on a display screen using a pointing device.

[Conventional technology]

In recent years, display devices used in image Q processing devices, expenditure preparation devices, etc. display multiple areas within a window on the display screen, and one area can be displayed using a pointing device.
Many of them have low display capabilities that allow you to select the 14th area. By the way, in such a display device,
For example, if you place many rectangular frames with item names on the screen and select an item by specifying a point within the rectangular frame, set the range of rectangular frame placement (display frame) to be wider than the window size. I can't. Therefore, in such cases, a means of scrolling the display frame is provided, and when selecting an area outside the window, the display frame is first set to scroll mode, and then the scrolling mode is set so that the specified area is displayed within the window. The user performs an operation, then returns to the area selection mode again and selects a predetermined area.

(Problem to be Solved by the Invention) However, in order to enter the mode in which the display frame is scrolled, after inputting a command to change the mode using the keyboard or pointing device, move the pointing device off the screen and move the scroll bar to the screen. This poses a problem in that operations such as displaying the area on the top of the screen must be performed, making the operation when selecting an area complicated.

This invention was made in view of the above-mentioned prior art, and is simple.
An object of the present invention is to provide a display control method that allows an area outside the view window to be selected with simple operations.

In order to solve the above problem, the display control method related to this defense uses a display control method to display the points indicated by a pointing device such as a cursor. Scroll m that calculates the scroll amount of the image from the pointing device control means for extracting the + mark data and the coordinate data of the two points input from the pointing device control means described in 11η.
The calculation means first determines in which region the coordinates of the designated point are located, and if the coordinates of the designated point are within a predetermined region, the display mode is set, and the coordinates of the designated point are determined. a designated area detection means that automatically sets a scroll mode when the coordinates are outside a predetermined area;
When the designated area detection means sets a display mode, an image of the selected area is created, and when a scroll mode is set, an image when scrolled is created by the scroll 0 calculated by the scroll amount calculation means. and a region data memory means for storing the coordinate data of each displayed region and the 8-point data of the selected region. In this case, the scroll mode is set, and an image is created and displayed when scrolling from the coordinate data of two points: 1ζ India, which was instructed to move away, and the point which was instructed next. be.

[Effect]

When a point on the screen is designated by the cursor, the pointing device control means takes out the coordinate data of the designated point and outputs it to the scroll amount calculation means and the designated area detection means. The designated area detection means determines in which area the designated point is located based on the current scroll amount of the screen possessed by the scroll mountain boundary exit means and the coordinate data of each area possessed by the area data memory means. do. Here, if the indicated point is within a predetermined area, that is, if any area is selected, the display mode is set and the data of the selected area is stored in the area data memory means. As well as newly entering the
A request is made to the image data creation means to update the image. In order to distinguish between the selected area and other areas, the image data creation means performs processing such as black and white inversion, and displays the image on the display screen.

On the other hand, if the indicated point is outside the predetermined area,
In other words, when no area is selected, the scroll mode is automatically set and the scroll f21W
When this is notified to the output means, the coordinate data of the indicated point is sent to jt. When the coordinate data of the next point is input from the pointing device control means, the scroll G closing means scrolls the display frame based on the coordinate data of the first designated point and the coordinate data of the second designated point. It is calculated and output to the image data creation means. The image data creation means uses the coordinate data of the area stored in the area data memory means and the calculated scroll ff1.
An image of the scrolling of the display frame is created based on the lc and displayed on the display screen.

As described above, in the display control method according to the present invention, if a point is specified within a desired area, the image of the specified area is displayed, and if a part other than the specified area is specified, the scroll mode is automatically turned on. The entire display frame is scrolled in accordance with the amount of movement from the first designated point to the next designated point.

〔Example〕

An embodiment of the display control method according to the present invention will be described below.

FIG. 2 is a block diagram showing the configuration of a workstation to which the display control method according to the present invention is applied. In the figure, 1 is a workstation control unit, 2 is a keyboard that displays various data and commands, 3 is a mouse that serves as a pointing device for moving a cursor and selecting an area, etc., and 4 is a display. The control device 5 is a CRT 8 display which is a display means for displaying a plurality of areas on the screen.

The workpiece controller 1 includes a micro brissor, a cursor controller 6 that extracts coordinate data of a point indicated by a cursor, and an image from the coordinate data of two points inputted from the cursor controller 6. Scroll stop output unit 7 that calculates the scroll value of
, it is determined which region the coordinates of the designated point 1- are within, and if the designated point is within a predetermined region, the display mode is set, and the coordinates of the designated point 8 are determined.
If the target is outside a predetermined area, a designated area detection unit 8 sets a scroll mode, and in a display mode, an image of the selected area is created, and in a scroll mode, an image of the selected area is created, and in a scroll mode, an image is calculated by the scroll ω calculating means. It is composed of an image data creation section 9 that creates an image when scrolling by scrolling m, and an area data memory section 10 that stores coordinate data of each displayed area and coordinate data of a selected area. .

Next, the operation of scrolling an image in the above-mentioned workstation will be explained using FIGS. 1(A) to 1(D).

FIGS. 1A to 1D are explanatory diagrams showing display states of the display 5. FIG. In the same figure (A), 11 to 1
Rectangular frames 4 and 21 to 24 are areas showing various parameters, etc. 31 is a window on the display screen, 32
represents a display frame in which each area is drawn. It is assumed that the window 31 in FIG. 1 is displayed on a portion of a display screen (not shown).

In the display state of the same figure (A>), there is area 1 in the window 31.
1 to 13 and 21 to 23 are displayed, but area 14
and 24 are not displayed because they are outside the window 31. When the user selects the area 14, he first points to a point P1 outside the area with the cursor. At this time, since point P1 is outside the area, the scroll mode is automatically set, and point P1 is displayed on the screen as a reference point for scrolling. Next, as shown in the same figure (B), move the cursor from point P1 to point P.
2 with the cursor, the display frame 32 scrolls according to the movement Q from point P1 to P2, as shown in FIG.
4 and 24 are displayed. Here Yunor is ff1M14
When selected with the cursor, the display state of the area 14 changes as shown in FIG. Note that the display frame 32 scrolls from the first designated point P1 to the next point P2.

Next, the processing procedure of the workstation control section 1 for realizing the above-described operation will be explained in detail based on the flowchart of FIG. 3 while referring to FIG.

When the user presses the button on the mouse 3 and specifies a point on the screen (step 101), the cursor control iD unit No. 6 outputs the coordinate data of the point specified by the cursor to the specified area detection unit 8. (Step 1o2
). As the scroll Flin output section 7 scrolls the current screen to the right, the indicated area detection section 8 detects the point indicated by the cursor based on the coordinate data of each area held in the area data memory section 10. It is determined whether it is within the area (step 103).

Here, if the coordinates of the designated point are outside the predetermined area, the designated area detection unit 8 displays a mark as a reference point at the designated cursor position via the display control device 4, and sets the scroll mode. (Step 1
04). Then, when a notification is sent that the scroll need has been set to the scroll suspension part 7, the coordinate data (XO, YO) of the reference point is sent out (step 105).
.

When the mouse button pressed in step 101 is depressed (step 106) and the coordinate data (XIYl) of the next point is input from the cursor control section 6 (step 107), the scroll mode section 7 first performs an instruction. From the coordinate data (XO, YO) of the designated point and the coordinate data (XLXl) of the next designated point, the scrolling angle of the image is calculated σ and outputted to the image data creation section 9 (Step 1
08). The image data creation unit 9 creates an image when the display frame is scrolled based on the coordinates of the area stored in the area storage unit 10 and the scroll suspension that is equalized, and displays the display system 61]g. 4 (step 109).

The display system 611 device 4 displays the image sent from the image data creation section 9 on the screen of the display 5 (step 110).

By the above-described processing procedure, the area that has been outside the window will be displayed (see FIG. 1(C)).

Next, the newly displayed area is selected by the user, but in this case, the cursor is pointed within a predetermined area, so steps 103 to 11 are performed.
0, and when the mouse button pressed in step 101 is released (step 111), it is again determined whether the cursor is within the area on the screen (step 112). If the cursor is located outside the area on the screen, it is determined that there was an operation error or that the area designation was canceled. Also, when the cursor is within the area on the screen, the display mode is set, data of the selected area is newly outputted to the area data memory unit 10, and the image is updated to the image data creation unit 9. 4!-Request (step 113).The image data creation unit 9 performs processing such as black and white inversion on the image of the selected area, and outputs it to the display control 11 PI/l (step 114).
. The display system device 4 displays the image sent from the image data creation section 9 on the screen of the display 5 (step 110).

In the embodiments described above, the case where the image is scrolled in the horizontal direction has been described, but the present invention is not limited to this, and it goes without saying that the image can also be scrolled in the vertical direction or diagonally.

[Effects of the Invention] As explained above, in the display control method according to the present invention, as soon as a point outside the area on one screen is specified, the mode of "Suffle" is automatically set, and the next Since the image is scrolled according to the movement 0 to the point specified by The operability when selecting the r-1 area that can be displayed can be greatly improved.
