As shown in FIG. 3 , first proceed to step 301 : determine whether each window is a minimized window or a non-minimized window, and capture window images of each window in different ways according to the determination result.

The window list module 12 of the window switching system 1 first obtains the identification code (handle) corresponding to each window for each opened window on the computer desktop, and sends it to the screen capture module 11 . The screen capture module 11 judges the state of each window as a minimized window or a non-minimized window according to these identification codes, and captures the window screens of each window in different ways according to the judgment result and processes them, so as to provide the window list module 12 with data to form a stereoscopic window list. Since the present invention is aimed at the situation that each window is a minimized window or a non-minimized window, the window screen of each window can be captured in different ways by the screen capture module 11, for convenience and clarity, the screen capture of this step The detailed process of capturing the window frame by the capturing module 11 will be described in steps 801 to 812 later.

Please refer to FIG. 4 and FIG. 5 together below. FIG. 4 is a schematic diagram of a computer desktop 5; FIG. 5 is a schematic diagram of a three-dimensional window list of the present invention. As shown in Figure 4, in this embodiment, assume that the user has opened a plurality of windows 41 to 46 on the computer desktop 5, and the plurality of windows 41 to 46 include at least one minimized window and at least one non-minimized window, each The windows 41 to 46 are used to display a corresponding window frame. In this embodiment, since the windows 41 to 44 are minimized windows, the windows 41 to 44 are only displayed in the taskbar 4, and the corresponding window images are not displayed on the computer desktop 5; the windows 45 and 46 are non-minimized In addition to being displayed on the taskbar 4, the corresponding window images 45s and 46s will be displayed on the desktop 5 of the computer. At present, the user uses the window 45 as a main window 60 , and its corresponding window image 45 s is displayed on the top layer of the computer desktop 5 .

When the window switching system 1 receives an execution command, the screen capture module 11 starts to process the window screens of the multiple windows 41 to 46 that have been opened on the computer desktop 5 according to the window identification code obtained by the window list module 12. Screen capture. In this embodiment, the user can click a shortcut (not shown) corresponding to the window switching system 1 on the desktop 5 of the computer by touch to input the aforementioned execution command to execute the window switching system 1, but not This example is limited. The frame capture module 11 will perform corresponding image processing on the captured window frames, such as scaling or deformation of the window frames, for use by the window list module 12, and the captured window frames will be stored in the storage module 15 middle.

Next step 302: forming a three-dimensional window list.

After the window list module 12 obtains each window frame from the storage module 15 , it will form a three-dimensional window list 50 according to each window frame. As shown in Figure 5, the three-dimensional window list 50 includes a plurality of list windows 51 to 56 corresponding to the windows 41 to 46, and the plurality of list windows 51 to 56 are arranged and displayed in a three-dimensional manner, wherein each list window 51 to 56 The screens of are taken from the window screens of the corresponding windows 41 to 46. The three-dimensional window list 50 includes a visible range 58 , which is set by the window list module 12 , and the list windows currently available for user operation are displayed within the visible range 58 . As shown in Figure 5, in this embodiment, only four list windows 52 to 55 can be displayed once in the visible range 58, while other list windows 51 and 56 are located outside the visible range, but this visible range 58 The number of list windows that can be displayed can be increased or decreased according to the size of the display screen, hardware performance or user settings, and is not limited to this embodiment.

In the formed three-dimensional window list 50, the window list module 12 will update the pictures of the list windows 52 to 55 located in the visible range, so that as the window pictures of the corresponding windows 42 to 45 change, The pictures of the list windows 52 to 55 are updated; however, the pictures of the list windows 51 and 56 outside the visible range are stopped from being updated, so that the utilization rate of the CPU and the memory can be reduced to achieve energy-saving effect.

While the window list module 12 updates the screens of the list windows 52 to 55 within the visible range, according to the different states of the windows 42 to 45 that have been opened, the screen capture module 11 will perform different screen captures. The window screens of the windows 42 to 45 are retrieved in an fetching manner for the window list module 12 to update the screens. The above-mentioned different states include window minimization or non-minimization.

Please refer to FIG. 5A . FIG. 5A is a schematic diagram of updated screens of the list windows 52 to 55 in FIG. 5 . As shown in Fig. 4, Fig. 5 and Fig. 5A, because window 45 is a non-minimized window, it means that this window 45 is currently being displayed on the computer desktop 5, so the window list module 12 will be for the list window 55 corresponding to the window 45. The screen is updated instantly. The window list module 12 will notify the screen capture module 11 to periodically capture the window frame 45s of the corresponding non-minimized window 45 (for example, capture twice per second) for the window list module 12 to update the frame of the list window 55 . For example, if the window 45 corresponding to the list window 55 in FIG. 5 is playing a movie, the picture of the list window 55 will be updated along with the captured window picture 45s, for example, the picture of the list window 55 in FIG. 5A the displayed screen.

As shown in Fig. 4, Fig. 5 and Fig. 5A, since windows 42 to 44 are minimized windows, it means that these windows 42 to 44 are only displayed in the taskbar 4 at present, and are not operated by the user temporarily, so the window list module 12 will update the screens of the list windows 52 to 54 corresponding to the windows 42 to 44 at one time, that is, the screen capture module 11 only captures the screens of the windows 42 to 44 once as the corresponding list windows 52 to 54 , and this picture will not be updated until the stereoscopic window list 50 is closed. For example, if the window 44 corresponding to the list window 54 in FIG. 5 is playing a movie, when the three-dimensional window list 50 is formed, the picture of the window 44 is captured as the picture of the list window 54, then this picture will not follow the movie. The content is changed and then updated, so the picture displayed by the list window 54 in FIG. 5A is still the same as that shown in FIG. 5 .

Step 303: Receive a touch operation command of the three-dimensional window list 50 .

The touch module 13 receives a touch operation instruction input from the three-dimensional window list 50 . The user can input corresponding touch operation instructions by sliding or clicking on the touch module 13 .

Then proceed to step 304 : move the plurality of list windows 51 to 56 or select one of the plurality of list windows 51 to 56 according to the touch operation instruction.

The control module 14 can control the movement of multiple list windows 51 to 56 in the three-dimensional window list 50 according to the touch operation instructions received by the touch module 13, or select one of the multiple list windows 51 to 56 as the main window .

Please refer to FIG. 6 , FIG. 6A and FIG. 7 together. FIG. 6 and FIG. 6A show schematic diagrams before and after a plurality of list windows 51 to 56 are moved, and FIG. 7 is a schematic diagram of switching and displaying the window 46 corresponding to the selected list window as a main window 60 . Assuming that the user slides anywhere in the three-dimensional window list 50 from right to left with a finger or any touch object (as shown by the arrow in FIG. 6 ), the touch module 13 receives the touch operation of the three-dimensional window list 50 instruction, the control module 14 moves a plurality of list windows 51 to 56 according to the touch operation instruction (as shown in FIG. 6A ). In this embodiment, according to the distance or force applied by the user's sliding touch, the moving speed or moving distance of the plurality of list windows 51 to 56 will also change accordingly. Next, as shown in FIG. 6A , assuming that the user has clicked the list window 56 displayed in the three-dimensional window list 50 (for example, click twice on the list window 56), when the touch module 13 receives the touch operation command , and transmit the instruction to the control module 14, the control module 14 selects the list window 56 according to the instruction, and switches and displays the window 46 corresponding to the list window 56 as a main window 60, as shown in FIG. 7 . Through the above touch operation on the three-dimensional window list 50, the user can switch the main window 60 from the original window 45 in FIG. 4 to the window 46 in FIG. 7, so that the window screen 46s corresponding to the window 46 is displayed on the desktop of the computer. 5, in order to achieve the purpose of window switching.

In addition, when the multiple list windows 51 to 56 are being moved, the window list module 12 stops updating the images of each list window 51 to 56 to avoid image sticking or image errors.

Please refer to FIG. 8 . FIG. 8 is a flow chart of capturing a window frame of a window according to the present invention, which details the capture technique of the window frame in the aforementioned step 301 . As shown in FIG. 2 , FIG. 4 , FIG. 5 and FIG. 8 , the screen capture module 11 can capture window screens of different windows 41 to 46 through steps 801 to 812 , and each step will be described in detail below. For convenience of description, the window 44 in the minimized state and the window 45 in the non-minimized state are taken as examples for illustration, and the same steps are adopted for other windows.

Step 801: Determine whether the window 44 or 45 is a minimized window or a non-minimized window.

After selecting a window 44 or 45, the frame capture module 11 determines whether it is a minimized window or a non-minimized window according to the identification code of the window 44 or 45 obtained by the window list module 12.

Step 802: Capture the window frame of the window 45 directly.

When step 801 determines that the window 45 is a non-minimized window, the frame capture module 11 can directly capture the window frame of the window 45 and store it in the storage module 15 after image processing for use by the window list module 12 .

Step 803 : Send the window frame to the window list module 12 .

The frame capture module 11 notifies the storage module 15 to send the captured window frame of the window 45 to the window list module 12 as the frame corresponding to the list window 55 .

Step 804: Determine whether the window 44 has been updated.

When step 801 determines that the window 44 is a minimized window, the screen capture module 11 then determines whether there is a screen update record of the window 44 to confirm whether the window 44 has been updated.

Step 805 : Close a display animation of the window 44 .

When step 804 determines that the window 44 has not been updated, the screen capture module 11 notifies the operating system to close a display animation of the window 44, and the display animation includes a window minimization animation and a window restoration to non-minimization animation. The so-called window minimization animation is the animation presented during the process of shrinking the window displayed on the computer desktop 5 to the taskbar 4, and restoring the window to a non-minimized animation is to restore the window displayed in the taskbar 4 This animation presented in the process of computer desktop 5 display. Because the whole process of capturing the frame of the minimized window is performed without the user seeing it, in order to meet the requirements of the subsequent steps, the frame capturing module 11 must first notify the operating system to close the display animation of the window 44 . If it is determined that the window 44 has been updated, then this process ends.

Step 806: Enter a hidden window mode.

The frame capture module 11 will make the window 44 enter a hidden window mode. After entering this mode, the window 44 will not be displayed on the computer desktop 5 in the non-minimized state, that is, the window 44 that returns to the non-minimized state will be hidden in the The desktop 5 of the computer, so that the user will not find out whether the window 44 has been restored to non-minimized, so as to facilitate subsequent steps.

Step 807: Restore window 44 to non-minimized.

After entering the hidden window mode through the aforementioned step 806, the screen capture module 11 will restore the window 44 from minimized to non-minimized (not shown in the figure), because the animation of restoring the window to minimized has been closed and hidden in the aforementioned steps. The window 44 returns to the display on the desktop 5 of the computer after it is not minimized, so the user will not see the execution process of this step from the desktop 5 of the computer.

Step 808 : Capture the frame of the window 44 .

After the window 44 returns to non-minimized, the frame capture module 11 captures the window frame of the window 44 and stores it in the storage module 15 after processing for use by the window list module 12 .

Step 809: Minimize the window 44.

After capturing the window frame of the window 44 , the frame capture module 11 minimizes the window 44 to return to the original state of the window 44 . Since the window minimization animation has been closed in the preceding steps, the user will not see the execution process of this step from the computer desktop.

Step 810: Leave the hidden window mode.

After the above steps are completed, the frame capture module 11 will cause the window 44 to leave the hidden window mode, that is, if the window 44 returns to non-minimized at this time, the user can see the window 44 displayed on the computer desktop 5 .

In addition, step 811 can also be executed after step 810: the recording window 44 has been updated.

Because the window 44 has completed the process of capturing the picture, according to the design of the present invention, there is no need to perform other picture capturing actions for the minimized window 44. In order to avoid the window list module 12 from updating the picture of the list window 54 every time , the screen capture module 11 will be notified to repeatedly capture the screen of the window 44, resulting in a waste of computer resources, so the screen capture module 11 will record that the window 44 has been updated. In this way, when the window list module 12 performs the update operation again, the screen capture module 11 can determine that the window 44 has been updated through the aforementioned step 804, and terminate the subsequent screen capture steps.

After step 810 or 811, execute step 812: enable display animation.

Since the window 44 has completed the frame capture process, the frame capture module 11 will notify the operating system to start the display animation that the window 44 was originally closed, so that the window 44 returns to a normal state. After step 812 is completed, return to step 803, and the screen capture module 11 notifies the storage module 15 to send the captured window frame of the window 44 to the window list module 12 as the frame corresponding to the list window 54 .

In addition, when the three-dimensional window list 50 is closed, the screen capture module 11 will clear the previously updated record for each minimized window, that is, set it to a non-updated state, so as to avoid creating the three-dimensional window list 50 next time. A misjudgment occurred for the window.

The window switching method and window switching system 1 of the present invention can operate a three-dimensional window list 50 in a touch manner to switch multiple windows, which is much more user-friendly than the way of switching windows with a keyboard in the known technology; and, in the present invention In , only the screen of the list window within the visible range is updated, and different screen update methods are adopted corresponding to different states of the window, so that the usage of CPU and memory can be effectively reduced, and the energy saving effect can be achieved.

To sum up, the present invention, regardless of its purpose, means, and efficacy, shows its characteristics that are completely different from the known technology. I urge the examiner to be aware of it and grant a patent as soon as possible to benefit the society. I really appreciate it. However, it should be noted that the above-mentioned embodiments are examples only for the convenience of description, and the scope of rights claimed in the present invention should naturally be determined by the scope of the claims, rather than limited to the above-mentioned embodiments.
