JPH05260405A - Screen display device for adjusting pattern shape - Google Patents

Abstract

PURPOSE:To improve the man-machine interface by displaying a graph representing the adjustment content in an adjustment quantity display graph so as to facilitate the adjustment operation of a screen display character or a display format. CONSTITUTION:An OSD (on-screen display) block 4 has a memory function storing an adjustment item for pattern shape adjustment, a graph representing the pattern shape corresponding to a lower limit and an upper limit of the adjustment quantity and an adjustment quantity display graph comprising a scale between both graphs and has a marker generating function representing a current adjustment quantity displayed on the scale. Then a signal representing a relevant adjustment item and a display graph of the adjustment quantity is read from the memory at the adjustment of the screen shape of a monitor, and a mixer circuit 1 mixes the signal with a video signal RGB. Then the result is displayed on a screen of a CRT display device 3 via a video output circuit 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen display device in a display monitor device, and more particularly, to image distortion, image size,
The present invention relates to a tube display device for adjusting the shape of a display screen such as an image position.

[0002]

2. Description of the Related Art Recently, displaying a message for operating, controlling or adjusting a device on a screen makes it easier to operate the device, that is, to improve the man-machine interface. Etc. have been widely practiced. Conventionally, on a display monitor, an adjustment item and an adjustment amount are displayed on the screen (OSD: On Screen Di) for screen adjustment.
is being performed. In the case of this type of screen display, a number indicating the set position of the electronic volume is used as the adjustment amount display, or the minimum or lower limit value (MIN) and the maximum or upper limit value (MA) of the adjustment amount are used.
It is usually displayed by a marker that moves between both displays of (X).

For example, as shown below, in the case of the adjustment relating to the thread winding strain on the screen, "PI" showing the adjustment item.
A number that changes from 0 to 64, for example, 18 is displayed following "C" (Example 1), or MIN and MA
It is practiced to display a scale between the Xs and then move the marker ◆ to display it (Example 2). (Example 1) PIC 18 (Example 2) PIC MIN ・ ・ ・ ◆ ・ ・ ・ ・ ・ ・ ・ MAX

[0004]

However, in such a display method mainly using numbers and characters, image distortion,
As a display when adjusting the image size and the image position, there is a problem that the adjustment content cannot be fully expressed or it is difficult to express it. Especially in the case of a recent large screen and multi-scan type display monitor, it is difficult to see the screen display because it is necessary to adjust from a remote position, and it is necessary to set the adjustment amount for each scan in the memory. Since there are many adjustments and there are many adjustments, improvements are required to improve the service efficiency of service personnel.

Therefore, the present invention is intended to improve a screen display device for adjusting the screen shape of a display screen in a display monitor device, and in particular, an OSD character or a display format therefor is improved so that an adjusting operation can be easily performed. And improve the man-machine interface.

[0006]

[Means for Solving the Problems] A screen surface for adjusting a screen shape is displayed by an adjustment item and an adjustment amount display graphic, and the adjustment amount display graphic shows a screen shape corresponding to a lower limit value and an upper limit value of the adjustment amount, respectively. It is composed of a figure and a scale between both figures, and the current value of the adjustment is displayed by a marker displayed on the scale.

[0007]

Since the figure showing the adjustment content is displayed in the adjustment amount display figure, the adjustment content can be grasped intuitively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an OSD (On Screen Di).
3 is a block diagram of a video output unit of a display monitor having a display (spray, screen display) function, where 1 is a mixing circuit, 2 is a video output circuit, 3 is a CRT display, 4
Is an OSD block. As the OSD block 4,
Character input type microcomputer, so-called O
An SD microcomputer is used and is provided with a memory that stores various adjustment items and figures for visually displaying the adjustment amount. When adjusting the screen shape of the monitor, the OSD block 4 reads out a signal of a display graphic of a corresponding adjustment item and an adjustment amount from a memory, mixes it with a video signal RGB in a mixing circuit 1, and then through a video output circuit 2 to a CRT display 3 Displayed on the screen. The OSD block 4 can also generate, for example, a crosshatch signal required for adjustment.

FIG. 2 shows an example of the display form. For example, in the lower part of the screen 10, "H PIN AMP" (11) showing the amplitude adjustment of the horizontal pincushion distortion as an adjustment item and its adjustment amount are displayed. Display figures (a) and (b) showing the screen shapes corresponding to the lower and upper limits, the scale (c) and marker (d) between them, and move the marker (d) according to the adjustment operation. The present value of adjustment is displayed according to the position of the lever.

This "H PIN AMP" adjustment item is for adjusting the pincushion distortion (e) and barrel distortion (g) in the vertical direction of the screen, as shown by the crosshatch projection screen in FIG. When the vertical strain is a pincushion type, move the electronic volume to the right while looking at the adjustment screen, and when it is a barrel type strain, move the electronic volume to the left to adjust to the screen without distortion (f). You can

FIG. 4 exemplifies other adjustment items (12) to (28) and a graphic for displaying the adjustment amount, and the adjustment items (11) to (23).
Indicates screen distortion, and adjustment items (24) to (28) relate to screen size and screen position. As you can see in these examples, the display of adjustment items is not constant,
In addition, the common name or common name is also included, and although it cannot be said that the contents of the adjustment are always clear only by displaying the adjustment items, the figure (a) and (b) shows the corresponding image distortion, image size, and image position visually and qualitatively, and since the adjustment contents are obvious, the adjustment person, This makes it possible to intuitively understand the adjustment content.

[0012]

As described above, according to the screen shape adjusting tube surface display device of the present invention, the display portion of the image distortion, the image size, and the adjustment amount of the image position is expressed visually and qualitatively. Therefore, the adjustment items can be intuitively grasped, the service efficiency of the service person is improved, and the general user can easily perform the adjustment, thereby improving the man-machine interface. In particular, it is extremely effective for reducing the difficulty in adjusting the screen shape of a display monitor having a large screen and the complexity of adjusting the screen shape in the multi-scan type.
In addition, this allows the adjustment items for serviceman control to be opened for some users.
