However, the display position of the slide knob is moved by using a pointing device such as a mouse, and the slide position of the display target in the display screen corresponds to the display position of the slide knob. When the configuration is controlled, if the range of movement of the slide knob, that is, the size of the display area of the slide knob is smaller than the display target, moving the slide knob cannot display all of the display target on the display screen. There was a problem.

Therefore, there has been considered a method of solving the above problem by increasing the slide amount of the display target on the display screen with respect to the movement amount of the slide knob. For example, when the slide knob is moved by 1 dot within the display area, the display target is moved by several lines, for example, 10 lines on the display screen.

However, with such a configuration, there is a problem that the slide of the display target on the display screen can be slid only in units of 10 lines, and smooth control of the slide of the display target cannot be performed.

Therefore, according to the present invention, when the screen size of the display screen is smaller than the display object, the slide control of the display object can be performed smoothly, and the display position of the display object can be confirmed by the display position of the slide knob. An object of the present invention is to provide a display control device capable of displaying all objects on a display screen.

[0009]

In order to achieve the above object, the present invention has a display screen having a predetermined screen size, and a screen size of the display screen is obtained by sliding a display target within the display screen. In a display control device for displaying a larger display object on the display screen, a slide knob display means for displaying a slide knob indicating a display position of the display object in the display screen, and the display object in the display screen. And a slide knob display control means for moving the display position of the slide knob of the slide knob display means by one unit with respect to the movement of a predetermined unit amount of the pointing device. And

[0010]

In the present invention, the display object on the display screen is slide-controlled in response to the operation of the pointing device. Further, the slide knob is moved by one unit corresponding to the movement of a predetermined unit of the pointing device.
Thereby, the slide position of the display target on the display screen and the position of the slide knob can be made to correspond to all the display targets, and the display target on the display screen corresponds to the operation of the pointing device, for example, Sliding line by line enables smooth slide control.

A slide knob 503a displayed on the slide knob display area 503 is displayed at the upper end of the slide knob display area 503 as shown in FIG. 4B. A pointer 504, which is controlled to move by the mouse 40, points to the upper end of the slide knob 503a.

In this state, it is assumed that the mouse 40 is controlled to move the pointer 504 downward by 1 dot. This state is shown by a broken line in FIG.

Then, by the process of correcting the mouse point position (step 106) shown in FIG. 8, the position is corrected so as to point the upper end of the slide knob 503a.

In this embodiment, when the mouse 40 is controlled to move the pointer 504 downward by 1 dot, the data to be displayed on the window 502 is slid downward by one line, Conversely, when the mouse 40 is controlled to move the pointer 504 upward by one dot, the data to be displayed on the window 502 is slid upward by one line.

Therefore, in this case, the window 502
The data to be displayed that is displayed above slides down one line, and as shown in FIG. 5A, 2 to 11 lines out of the 1000 lines of data 700 to be displayed are windows. It will be displayed on 502. In this state, since the position of the pointer 504 has been corrected, the pointer 504 points to the position indicated by the solid line in FIG. 5B. Here, since the movement amount of the pointer 504 is 10 dots or less, the slide knob 503a displayed in the slide knob display area 503 does not move.

Next, in this state, it is assumed that the mouse 40 is controlled to further move the pointer 504 downward by 9 dots. This state is shown by a broken line in FIG.

As a result, the data to be displayed displayed on the window 502 is slid further downward by nine lines, and as shown in FIG.
From line 0 of data 700, lines 11 to 20 are displayed on window 502.

In this state, since the pointer 504 has moved by 10 dots from the initial state shown in FIG. 4, the slide knob 503a displayed on the slide knob display area 503 is moved by 1 dot. Also,
At this time, the pointer 504 has moved to the position indicated by the broken line in FIG.
As indicated by the solid line in (b), the point position is corrected by the above-described mouse point position correction (step 106) processing so as to point to the upper end of the slide knob 503a.

Next, in the state shown in FIG. 6, it is assumed that the mouse 40 is controlled to further move the pointer 504 downward by 3 dots. This state is shown by a broken line in FIG. At this time, the position of the pointer 504 is also corrected by the process of correcting the position of the mouse point (step 106) so as to point to the upper end of the slide knob 503a.

As a result, the data to be displayed displayed on the window 502 is slid downward by three lines, and as shown in FIG. 7A, the data 700 of 1000 lines to be displayed is selected. The 14th to 23rd lines are displayed on the window 502.

In this state, the pointer 504 is pointing to the position indicated by the solid line in FIG. 7B because the position has already been corrected. However, since the amount of movement of the pointer 504 is 10 dots or less from the state shown in FIG. 6, the slide knob 503a displayed in the slide knob display area 503 does not move from the state of FIG. 7B.

In the above description, the case where the mouse 40 is controlled to move the pointer 504 downward has been described.
The same applies when the mouse 40 is controlled to move the pointer 504 upward.

As described above, in this embodiment, when the mouse 40 is controlled to move the pointer 504 downward by one dot, the data to be displayed on the window 502 is slid downward line by line. On the contrary, by controlling the mouse 40 and moving the pointer 504 upward by one dot, the data to be displayed displayed on the window 502 can be slid upward by one line, and the slide knob The slide knob 503a displayed on the display area 503 is moved downward or upward each time the amount of movement of the pointer 504 reaches 10 dots. Here, slide knob 503
Since the movement of 1 dot of a is controlled so as to correspond to 10 lines of the display target data displayed on the window 502, all 1000 lines of the data 700 to be displayed are displayed on the window 502. It becomes possible to display.

The display control is controlled by the central processing unit (CPU) 10 shown in FIG. 1. Next, the display control by the central processing unit (CPU) 10 is shown in FIG. This will be described with reference to the flowchart shown in FIG.
