Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display monitor having a system display area (menu bar) display function for operating a window screen displayed on a display screen of a CRT, for example.

[0002]

2. Description of the Related Art Conventionally, a display monitoring apparatus having a window screen display function, when the screen size of the window displayed on the display screen is reduced, the system display area (menu bar) in the window and its The internal menu buttons and touch area are also reduced.

Now, the actual size processing operation of the system display area of the conventional display monitor will be described.

In the system display area of the window screen displayed on the display screen of the CRT of the display monitor, a plurality of menu buttons (operation buttons) are arranged at predetermined positions. The touch area is set to the same size. When the user selects and touches a desired button among these menu buttons, the desired screen is displayed and various operations can be performed.
Among the menu buttons, for example, there is a resize button (resize button, enlarge button, etc.) for resizing the window size.

Therefore, when the user resizes the window size as desired, the window size is resized by touching the display position of the resizing button on the screen. Along with this, the menu button in the window and the touch area assigned to it are also resized. In addition, touch areas are allocated to display objects that require touch operations other than menu buttons, and the display objects and touch areas are also resized as the window is resized.

The operation of the system display area and screen when the window size is reduced will be described.

In this case, first, when the window size becomes smaller, the sizes of the system display area, the menu button, and the screen display section are recalculated and displayed in a form adapted to the size of the window. At this time, the touch area assigned to the menu button and the screen display unit is also reduced and corrected according to the window size.

By the way, the touch operation may become difficult depending on the size of the window. In the case of various monitoring devices, such as a plant monitoring device that monitors the status of a power plant, many screens of characters to be monitored (valves, relays, etc.) are displayed in one window screen. Even in the size, the display size around one picture is small. Therefore, when the size of this screen is reduced, it becomes difficult to identify the character pattern itself and it becomes difficult to perform a touch operation on a desired character.

In addition, this type of monitoring device is not allowed to be erroneously operated, and in any case, the processing of each character must be performed by a simple operation, accurately and quickly.

[0010]

As described above, in the conventional display monitoring apparatus, when the window screen is made small, when the user touches a desired touch area in the window screen, the touch area is narrow and the screen is small. However, there is a problem that the operability is deteriorated due to the inability to perform the operation quickly.

The present invention has been made in order to solve such a problem, and improves the operability as a plant monitoring device, enables quick response monitoring, and improves the function of the entire system. The purpose is to provide a monitoring device.

In this case, if the size of the menu button in the system display area is set to a lower limit (minimum size that can be easily touched), and if the menu button becomes below the lower limit value due to resizing of the window, the menu button is set below the lower limit value. For menu buttons that do not fit in the system display area without being reduced in size, the new [NEXT] button is used to switch pages and display a new page so that menu touch input can be performed quickly and accurately. You will be able to do it.

According to the second aspect of the present invention, a pattern display means for displaying a monitored pattern having a touch area set within a predetermined range on the window screen, and a request receiving means for receiving a resizing request for the window screen. A calculating unit for calculating a size for resizing the window screen, the monitored pattern and the touch area in response to the resizing request received by the request receiving unit; and the touch calculated by the calculating unit. A comparison means for comparing the resize value of the area with a preset lower limit value of resizing, and a comparison result, if the calculated resize value is smaller than the lower limit value of the resize, a new window screen resized by the calculated value. A touch area enlarging means for enlarging the area of the touch area inside, and the touch area enlarging When the touch area which is enlarged by the step is selectively operated, the picture of the monitored, and a picture enlargement means for enlarging the size corresponding to the expanded touch area.

That is, according to the present invention, a lower limit (minimum size for easy touching) is provided in the touch area, and when the pattern to be monitored is reduced as the window screen is reduced, the touch area assigned to it is reduced. When the size is smaller than the lower limit, the touch area is enlarged, touch input is enabled even if the area near the reduced pattern is touched, and the touched pattern is enlarged and displayed. A magnifying function is provided so that the touch input can be easily performed on the pattern to be monitored that is really desired to be touched.

In this case, when the window is contracted, the touch area allocated to the pattern to be monitored is enlarged, and the touch input is valid even if the vicinity of the contracted pattern is touched. Then, by touch-inputting the vicinity of the design, the design is enlarged and displayed, and the touch-input of the design to be really touched becomes easy.

As a result, the touch operation on the window screen can be performed quickly and accurately, and the operability of the entire system can be improved.
