Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, it should be noted that the shapes, sizes, etc. of the components shown in the drawings may be exaggerated for clarity.

1 is a flowchart illustrating a drawing operation control method using a transparent window according to an embodiment of the present invention.

In the method of controlling a drawing operation using a transparent window according to an embodiment of the present invention, when a command for executing a transparent window of a user is input, setting a property of a transparent window and a picture property related to a picture drawn on the transparent window (S11), displaying the transparent window according to the set transparent window property, performing a drawing operation on the displayed transparent window (S12), and generating a user input for suspending the drawing operation following the pointer movement. The method may include a step S13 of determining whether or not a user input for suspending the drawing operation occurs, and a step S14 of executing a function corresponding to the location of the pointer under the transparent window.

In order for a user to draw on a display of a computer system using a pointer, a user may first input a command to execute a transparent window serving as a background for drawing.

The pointer is a general input device that receives a user's input on the display, and a variety of user inputs such as a keyboard, a mouse, a laser pointer and a remote controller, a touch pad that receives a touch input, an infrared touch sensor, an ultrasonic touch sensor, a camera touch sensor, and the like. The location may be determined by at least one of the devices.

The user can predetermine the properties of the transparent window and the properties related to the picture drawn on the transparent window or at the time of executing the transparent window.

The computer system sets the properties of the transparent window determined in advance or determined together with the user's transparent window execution command (S11) and the properties related to the picture drawn on the transparent window (S11) and displays the transparent window accordingly (S12). Inputs a command to execute a transparent window (for example, a command executed by double-clicking an icon), stops the drawing operation and changes the window property to perform a function corresponding to the position of the corresponding pointer under the transparent window. S14) double click is executed.

For example, the property of the transparent window may include information about transparency, size, shape, position, color, and brightness of the transparent window, and information about a user input for suspending a drawing operation. In addition, the property of the picture may include the size and shape of the pointer for drawing the picture, the line thickness and color of the picture.

The displayed transparent window can be set to the highest window. Even when other applications or windows are running on the computer system, the transparent window is set and displayed as the topmost window. If the transparent ratio is set to 100% among the properties of the transparent window, even if the transparent window exists on the top of the display screen, the previously running application or window can be seen as it is.

The transparent window may be manufactured by applying various techniques using a basic window defined in an operating system (for example, Windows XP, Windows Vista, Windows 7, MAC, Linux, etc.) of a computer system by a known technology. .

For example, the transparent window to be implemented in the present invention has a method of directly controlling a pixel to make a transparent window by directly mixing bit values of the window color of the screen and the remaining window color. And when creating a window, there is a transparent window with only the size and area without anything on the blank screen. In addition, the technology for transparent windows that has existed since the time of Microsoft's Win98 era is the Alpha Blending technique, which is a transparent window that creates a transparent screen by transparency (ALPHA) of one screen and the other screen of the screen. There is also a transparent window that uses a specific masking color to erase only the mask color from the window, making it transparent. In addition, since Vista and Win7 have recently been studied techniques for full-scale transparent processing, various transparent window techniques have emerged. Recently, transparent windows through layered window properties have also emerged. Finally, transparent windows such as the Click-Through technique, which pass through the transparent window without receiving a message event, are coming out.

When the drawing operation is executed by moving the pointer, a picture is drawn on the transparent window existing at the top, so that the desired picture can be drawn without being affected by the existing running application or window.

3A to 3B are exemplary views illustrating an example of a screen on which a transparent window according to an embodiment of the present invention is displayed.

For example, FIG. 3A illustrates an example in which the transparent window 40 is disposed on the display screen 30 of the computer system. As shown in (a) of FIG. 3, according to the present invention, the application 31 for the video lecture is executed at the bottom of the transparent window while watching the video lecture, while using the pointer on the transparent window 40. A memo 32 or the like for a video lecture may be written on the display by performing a drawing operation.

Referring back to FIG. 1, in one embodiment of the present invention, determining whether a user input for suspending a drawing operation following the movement of the pointer occurs (S13) and a user input for suspending the drawing operation occurs. In this case, the method may include executing a function corresponding to the pointer position under the transparent window (S14).

In one embodiment of the invention, the transparent window can behave as if no transparent window exists for the inputs other than the input for the drawing operation. For example, by making the transparent window click-through, it is possible to execute a function disposed under the corresponding position of the pointer when another input exists.

An example of such a configuration of the present invention is shown in FIG.

As illustrated in FIG. 3A, it is assumed that an Internet search is required while drawing on a specific area 32 while watching the video lecture 31 using the transparent window 40. The pointer 33 is moved onto the Internet browser execution icon 34 existing on the desktop under the transparent window and double-clicked. This double click can be recognized as an input that stops the user from drawing.

While the transparent window is displayed, it is determined that the user's double click is not an input for a drawing operation, and accordingly, the icon 34 of the lower part of the transparent window corresponding to the position where the pointer 33 exists is inputted as a double click. As shown in FIG. 3B, the Internet browser 31 ′ may be executed. However, the drawing contents so far remain.

On the other hand, after executing a function corresponding to the pointer position (S14), if a predetermined time elapses or a preset return input occurs, it may return to step (S12) to perform the drawing operation.

On the other hand, as described above, the transparent window 40 may again become the top window by the top-level windowing process (S13 and S14) of the transparent window is made at any time, and the drawing operation is again performed on one region 35 on the transparent window. Can be done.

As described above, when an input other than an input for a drawing operation occurs, the present invention performs the functions of the lower part of the transparent window corresponding to the corresponding pointing position, thereby allowing other applications and other computer functions to be executed while the drawing operation is performed. You can let it run.

2 is a flowchart illustrating an operation for maintaining a transparent window as the topmost window in one embodiment of the present invention.

Referring to FIG. 2, according to an exemplary embodiment of the present disclosure, determining whether the transparent window is the highest window (S21) and when the transparent window is not the highest window, setting the transparent window again as the highest window ( S22) may be further included.

As described above, the drawing operation needs to be performed on the transparent window in order for the drawing operation to be performed without being interrupted or erased. To this end, one embodiment of the present invention repeatedly checks whether the transparent window is the highest window according to a preset period (S21), and automatically sets the transparent window to be the highest window (S22) if it is not the highest window. Can give

Accordingly, one embodiment of the present invention can be painted without being erased or interrupted regardless of the operation of other applications or windows.

Meanwhile, in one embodiment of the present invention, as illustrated in FIG. 4, a plurality of transparent windows may be arranged to perform a drawing operation. 4 is an exemplary diagram illustrating a display screen on which a plurality of transparent windows 40 and 41 are executed, according to an embodiment of the present invention.

The plurality of transparent windows may use transparent windows manufactured by two or more different techniques among the various transparent window fabrication techniques described above. That is, the plurality of transparent windows are transparent windows manufactured using at least two processes, such as alpha blending technique, direct pixel processing, layered window attribute, transparent window made of blank screen, and click-through as mentioned in the background art. It may include.

In this embodiment, the plurality of transparent windows have mutually different transparency, at least one of the plurality of transparent windows is applied to receive an input value by the pointer, and at least one or more of all the transparent windows are connected to the input value. It can be applied to draw a picture.

For example, when drawing through a single transparent window, the drawing itself becomes transparent because the screen itself is transparent. Therefore, if you want to make the drawing opaque, you can draw on other transparent windows to make it opaque.

As shown in FIG. 4, two transparent windows 40, 41 are applied and applied, and the transparency of the topmost transparent window 41 of FIG. 4 is lowered to the minimum so that the lower part can be seen as it is and the other transparent underneath. If you make a window 40 and draw a transparent window of a blank screen instead of a window made of transparency, the transparent window 40 can be opaquely drawn.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the scope of the present invention should not be limited to the embodiments described, but should be determined by the scope of the following claims and equivalents thereof.
