The present invention relates to a control bar of the GUI elements, and more particularly, to a control bar display device and a numerical adjustment method using the same.

Commands or techniques used by computer systems or programs to control data entry or operation are called user interfaces. Today's computers are becoming more than just a computing machine, but a tool to enhance your creativity. The user interface supports these creative activities and improves the performance of the system as a whole. When DOS was used as a computer operating system, a textual user interface was used. However, widely used operating systems such as Windows and Linux support Graphical User Interface (GUI), which displays a list of actions as icons or menus, and allows users to perform tasks with the mouse. Do it.

The control bar is one of these graphical user interface elements and is used to adjust the volume of an OSD (On Screen Display) menu or an application program. Here, the OSD (On Screen Display) refers to a function of directly displaying on the screen information needed by the user or information about the monitor. This information includes the brightness of the screen, the contrast of the screen, tuning, RGB adjustments, and the vertical and horizontal size and position of the screen.

As shown in FIG. 1, the OSD menus may be set by operating OSD menu control buttons 110, 120, 130, and 140 implemented at a specific position of the monitor. OSD menu For example, when the [Brightness] menu is selected, as shown in FIG. 2, a control bar 220 indicating a type 210 and an adjustable range of the selected menu, and a number 230 indicating a current setting value are shown. GUI 200 is outputted.

As shown in FIG. 2, after the control bar for the screen brightness is output, when the right button 140 is applied, the setting value for the brightness is increased by one step each time the right button 140 is applied. On the contrary, when the left button 130 is applied, the brightness of the screen is lowered by one step each time the left button 130 is applied. In this way, the user can adjust the brightness or contrast of the screen, and the size and position of the screen.

The control bar is also used to control the behavior of the application. 3 illustrates an example of a user interface for adjusting a volume or playing speed of a music in a music playing program, and an adjustment point 320 for displaying a current setting value for a controlled menu such as a volume and a playing speed. Control buttons 310 and 330 are provided to increase or decrease the controlled menu. In this case, whenever the adjustment buttons 310 and 330 are applied, the adjustment point 320 is moved to the left or the right, and the setting value is displayed at the predetermined position 340.

However, in the conventional control bar adjusting method, there is a problem in that the control buttons 310 and 330 are applied as desired steps in order to adjust the size of the menu. For example, if you want to increase the music playback speed from 10 to 20, you need to apply the increase button 330 20 times.

In addition, since the current value information and numerical adjustment buttons for the menu are distributed, it is inconvenient to check the control point and the current value information alternately.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a control bar display device capable of operating a control bar more quickly and a numerical adjustment method using the same.

However, the objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, a control bar display apparatus according to an exemplary embodiment of the present invention includes an input unit including direction buttons for increasing or decreasing a set value of a controlled menu, a memory in which a current selection value and information of a selected controlled menu are stored. The control bar indicating a control menu of the controlled menu, the controlled menu, a control point on which a current selection value of the controlled menu is displayed, and a numerical value on which selectable values of the controlled menu are displayed based on the control point. And an OSD menu generator for outputting a graphical user interface including a bar.

In addition, the numerical control method using the control bar display device according to an embodiment of the present invention in order to achieve the above object is a step of outputting and inputting a graphical user interface for changing the setting of the controlled menu according to the selection of the controlled menu; Determining a type of a direction key to be used, and increasing or decreasing a current selection value of the controlled menu at a predetermined interval according to the determination result, wherein the graphic user interface includes: a control bar indicating an adjustment range of the controlled menu; And an adjustment point at which the current selection value of the controlled menu is displayed and a numerical value bar on which selectable values of the controlled menu are displayed based on the control point.

Hereinafter, in the description of the present invention, a case where the present invention is applied to the adjustment of the OSD menu of a monitor of a computer, for example, a CRT monitor, will be described as an embodiment.

4 is a block diagram illustrating a structure of a monitor applied to an embodiment of the present invention. The function and operation of each part will be described with reference to the following.

As shown in FIG. 4, the monitor 400 applied to an embodiment of the present invention includes a key input unit 430, an image signal output unit 410, an OSD menu generator 450, a controller 420, and an image output unit. 470, an image signal processor 440, and a memory 460.

The image signal output unit 410 supplies R, G, and B three primary color image signals provided from a computer to the image signal processor 440, and outputs a horizontal sync signal H-SYNC and a vertical sync signal V-SYNC. The control unit 420 is provided.

The image signal processor 440 receives the R, G, and B image signals provided from the image signal output unit 410, converts each signal to a predetermined level, and provides the converted image signal to the image output unit 470. In addition, when there is a user input through the key input unit 430, the OSD image signal provided by the OSD menu generating unit 450 and the image signal provided by the image signal output unit 410 are synthesized and provided to the image output unit 470. .

The image output unit 470 adjusts the gain of the R, G, B image signal provided by the image signal processor 440 or the image signal for the OSD menu, and outputs the gain to the cathode ray tube 480.

The key input unit 430 displays an OSD menu list and generates a command signal for adjusting a numerical value of the selected OSD menu. As illustrated in FIG. 5, the OSD may display an OSD menu list and select an OSD menu. The menu button 510 includes direction buttons 520, 530, 540, and 550 for adjusting a value of a selected OSD menu, and a power button 500 for supplying power to the monitor.

The OSD menu button 510 allows an OSD menu list to be output and allows one of the OSD menus to be selected from the output OSD list. For example, when the OSD menu button 510 is first applied, the monitor 400 outputs an OSD menu list including brightness, contrast, horizontal, vertical position and size. After that, use the direction buttons to make the OSD menu, for example, [Brightness] highlighted, and then apply the OSD menu button again. The [Brightness] item is selected to adjust the brightness of the screen. The GUI is output.

In the case of the direction buttons 520, 530, 540, 550, four directions of the up button 520, the down button 540, the left button 530, and the right button 550 to adjust the value of the selected OSD menu. It is preferable to be provided with a button.

The controller 420 determines the horizontal synchronizing signal and the vertical synchronizing signal provided from the image signal output unit 410, and outputs a control signal to the OSD menu list and the user according to the command signal generated from the key input unit 430. Allows the selected OSD menu to be displayed.

The OSD menu generator 450 outputs an OSD list according to the command signal of the key input unit 430 and an image signal for the selected OSD menu, and provides the same to the image signal processor 440. In addition, the OSD menu generating unit 450 refers to the information stored in the memory unit 460, and outputs a graphic user interface for changing a setting value of the selected OSD menu. Subsequently, when the direction key is applied, the selected value is increased or decreased according to the type of the applied direction key, and the selected value is highlighted. A more detailed description thereof will be described later together with the description of the GUI according to the present invention.

The memory unit 460 stores information related to each OSD menu, for example, intervals of numerical values selectable for the corresponding OSD menu, and current setting values for the corresponding OSD menu. For example, if the brightness of the screen is changed to 90 and the contrast is set to 95 by manipulating the key input unit 430, the changed values are stored in the memory unit 460. The memory unit 460 may be implemented as a memory device such as a cache, a ROM, a PROM, an EPROM, an EEPROM, a flash, an SRAM, and a DRAM, but is not limited thereto.

Next, the GUI displayed when the OSD menu is selected according to an embodiment of the present invention will be described. 6A, 6B, 6C, 6D, 6E, and 6F illustrate the structure of a control bar displayed on a screen when an OSD item of a monitor is manipulated according to an embodiment of the present invention.

When the OSD menu list is output by applying the OSD menu button 510, the OSD menu to change the setting is highlighted by operating the direction keys 520, 530, 540, and 550. For example, if the menu to change the setting is highlighted, and then the menu button 510 is applied again, the [Contrast] menu is selected to set the [Contrast] as shown in FIG. 6A. The GUI that can change is displayed.

As illustrated in FIG. 6A, the GUI 600 according to an exemplary embodiment of the present invention includes the type 610 of the OSD menu, a control bar 620 indicating an adjustment range for the OSD menu, and overall adjustment of the currently set value. Control points 630 to indicate locations within a range.

According to the exemplary embodiment of the present invention, information on the current setting value is preferably displayed in numbers in the region of the adjustment point 630. For example, if the current value for the Contrast menu is set to 90, it is preferable to display the number 90 at the adjustment point.

In addition, when the OSD menu is output, it is preferable that a numeric display bar 640 including a numerical value selectable by a user is output. At this time, it is preferable that the selectable values are output in a bar form perpendicular to the control bar on the basis of the adjustment point, so that the selectable values can be selected by manipulating the up and down keys among the four direction keys implemented in the key input unit.

In addition, it is preferable that the selectable numerical values are output at predetermined intervals from the currently set values. For example, if the [contrast] menu is currently set to 90, the selectable value causes the numbers to be spaced 20 apart from the current setting. That is, 70, 50, 30, 10 and the minimum value are output below the adjustment point labeled 90, and the maximum value of the adjustment range, for example, 100, is output above the adjustment point.

In this state, when a key of the key input unit 430 is applied, the selected number is highlighted according to the type of the applied key. For example, in the state shown in FIG. 6A, if the up key 520 of the key input unit 430 is applied, as shown in FIG. 6B, 100, the maximum value of the adjustment range, is selected and the selected number is highlighted.

If the down key 540 of the key input unit 430 is applied three times in the state as shown in FIG. 6A, as shown in FIG. 6C, 30 is selected and the selected number is highlighted. At this time, the control point continues to display a value of 90.

In addition, if the right direction key 550 of the key input unit 430 is applied in the state as shown in FIG. 6A, as shown in FIG. 6D, the position of the adjustment point 630 moves to the right by 1, and is adjusted. The value displayed at the point 630 is increased by 1 from the value 90, that is, 91. In the upper part of the adjustment point 630 indicated as 91, the maximum value of the adjustment range is displayed as a selectable value, for example, 100, and as the selectable value below the control point, 71, 51, 31, 11, and 0. Are displayed.

On the contrary, in the state shown in FIG. 6A, if the left key 530 of the key input unit 430 is applied, as shown in FIG. 6E, the position of the adjustment point 630 is moved by 1 to the left, and the adjustment point ( The value displayed at 630 is 1, which is reduced by 1 from the value 90, that is, 89 is displayed. In addition, the control point 630 indicated as 89 is displayed as a selectable value 100, which is the maximum value of the adjustment range, and in the lower part of the control point 630 as a selectable value 69, 49, 29, 9 and 0. Is displayed.

Meanwhile, as shown in FIG. 6C, when the menu button 510 is applied while 30 is highlighted, the contrast of the screen is set to 30 as shown in FIG. 6F. Alternatively, even when there is no key input for a predetermined time, for example, 3 seconds or more with 30 being highlighted, the contrast of the screen is set to 30, and at the same time, the [Contrast] menu disappears from the screen.

Meanwhile, the selectable interval may be increased in proportion to the overall adjustment range. For example, if [Brightness] is adjustable within the range of 0 to 200 and [Contrast] is within the range of 0 to 100 in the OSD menu, when the [Brightness] menu is selected, the numeric display bar 640 The interval between the numerical values displayed on the screen may be 30, and when the [contrast] menu is selected, the interval between the numerical values displayed on the numerical display bar 640 may be 20.

In addition, when the numeric display bar 640 is output, the minimum value and the maximum value for the adjustment range of the corresponding OSD menu may be always output regardless of the interval of the selectable numerical value. For example, the contrast menu is adjustable within the range of 0 to 100, and the selectable interval is 20. If the currently set value is 85, the numeric display bar 640 is output. In the upper part of the adjustment point, 100, which is the maximum value of the adjustment range, is output, and in the lower part of the control point, 65, 45, 25, 5, and 0, which is the minimum value of the adjustment range, may be output.

In the GUI as described above, a process according to the control bar operation according to an embodiment of the present invention is shown in a flowchart as shown in FIG. 7.

First, when the menu button 510 is applied, an OSD menu list is output (S710). At this time, the OSD menu to change the setting by operating the direction keys (520, 530, 540, 550), for example, after selecting the [Contrast] menu (S720), if the menu button 510 is applied again, Figure 6a As shown, a GUI including a control point 630 indicating a current value for [contrast] and a numerical display bar is outputted so that the setting for the [contrast] menu can be changed (S730).

Thereafter, the controller 420 determines whether there is a direction key input (S740), and when there is a direction key input, the controller 420 determines the type of the input direction key (S750).

As a result of determination, if the uplink key 520 is applied, the value increased by one step from the currently set value is selected, and the selected value is highlighted (S761). The step here refers to the interval displayed on the numerical value bar 640. For example, when the up key is applied in the state as shown in FIG. 6A, as shown in FIG. 6B, the maximum value 100 is selected.

On the contrary, as a result of determining the type of the direction key (S750), if the down key 540 is applied, the value is reduced by one step from the currently set value, that is, in the numerical display bar, below the step based on the adjustment point 630. The selected value is selected (S762).

On the other hand, as a result of determining the type of the direction key (S750), if the left key 530 is applied, the value is reduced by 1 from the currently set value is selected. At this time, as shown in FIG. 6E, the adjustment point 630 is moved by 1 to the left, and a value of 89 smaller than 90 is displayed in the area of the adjustment point 630 (S763).

On the contrary, as a result of determining the type of the direction key, if the right direction key 550 is applied, the value increased by 1 from the currently set value is selected. At this time, the adjustment point 630 is moved to the right by one, as shown in FIG. 6D, and a value 91 is displayed in the area of the adjustment point 630 (S764).

After that, if the direction continues to be manipulated, the operation according to the signal is repeated and the selected number is highlighted accordingly.

Thereafter, the controller 420 determines whether there is no input through the key input unit 430 for a predetermined time, for example, 3 seconds (S770). As a result, if there is no key input for 3 seconds, the currently selected value is determined as the set value, and the set value is stored in the memory unit 460 (S790). If it is determined whether the input is performed through the key input unit 430, if there is a key input within 3 seconds, it is determined whether the input key is a signal for the OSD menu button 510 (S780).

As a result of determination, if the OSD menu button 510 is applied, the currently selected value is determined as a setting value, the set value is stored in the memory unit 460, and the GUI for the corresponding OSD menu disappears. . If, as a result of the determination, the OSD menu button is not applied, the type of the applied button is determined again (S740), and the operation according to the determination result is performed.

With reference to the drawings illustrated as above, the control bar display device and the numerical adjustment method using the same according to the present invention has been described, but the present invention is not limited by the embodiments and drawings disclosed herein, of the invention Of course, various modifications may be made by those skilled in the art within the scope of the technical idea.
