Description

Method for processing desktop background, device and operating system desktop interface system The present application claims to be submitted to the Chinese Patent Office on November 30, 2006, the application number is 200610145986.7, and the invention name is "a method and device for processing desktop background". Priority of the patent application, the entire contents of which is incorporated herein by reference.

Technical field

The present invention relates to the field of background processing, and in particular, to a method and apparatus for processing a desktop background and an interface system of an operating system desktop.

Background technique

In the computer system, for the convenience of the user, the shortcut links for starting various operating system functions and applications are graphically displayed, placed on the screen of the computer display, and can be activated according to the operation of the user on these shortcut links. The corresponding application or the corresponding function, according to the Windows naming convention, this shortcut link is also called shortcut or shortcut icon. Quick links may also use menu items or control buttons as expressions. They may be displayed directly on the screen, or they may be classified and displayed. The screen displayed on this screen is called the desktop of the computer system. At the same time, the pictures can be set. As a desktop background, make the screen display more colorful. The desktop background occupies most of the desktop area, and the desktop background is reasonably set, which makes the desktop beautiful, the user feels happy, and makes the computer more human.

At present, the processing method of the desktop background image is mainly to use the desktop background image processing program provided by the operating system for the user, and the related function interface needs to be opened to operate. For example, in the Windows XP computer operating system, the operating system provides the processing functions of the display state of the three methods of stretching, tiling and centering of the desktop background image, and these functions need to be performed by the user in multiple steps. For example, to select "D:\My Documents\My Pictures\Background 2.jpg" as the desktop background, you need to select the "Properties" item of the menu item in the context menu of the desktop, and select "In the dialog window that opens". Background "Options page, then select the "Browse" button, open the file selection dialog box, select and open the local disk D drive, "My Documents" and "My Pictures" directory in the dialog box, then select in the file list "Background 2.jpg" file, select the "OK" button, and then you can choose how the image is processed. You can set it to tiling, centering or stretching. Finally, select the "OK" button and select the selected image according to the selection. The way it is processed is displayed on the desktop background. When you need to adjust the display effect, you need to repeatedly enter the above interface to re-select the processing method. In terms of display effect, the centered state provided in Windows XP can display the image in a fixed area in the center of the desktop background; the tiled state can repeatedly display small images on the entire desktop background, and for large images, only the upper left corner of the image is displayed. The stretched state fills the image with the entire adaptive desktop background as a whole. The resolution of the existing "wallpaper" image (the image file used for desktop background) is usually adjusted to 1024*768 which is suitable for the resolution of ordinary display, with the gradual popularization of large-size and wide-screen displays and high-resolution pictures ( For example, if the resolution of 2000* 1500 is used, the existing desktop background image processing method has the following problems:

1. When you need to process the desktop background image, you must enter the menu or dialog box to process the selection. The user has many steps and is inconvenient.

2. Only three treatment methods: tiling, centering or stretching are provided. The processing method is limited, and the display may be incomplete or display deformation, and the effect of the desktop background image may not be well handled.

3. For high-resolution images, after stretching, fill the entire desktop background according to the size of the image, or just display it in the center of the screen or just the top left corner of the image. It is not enough for the user to directly enlarge or directly specify the specified area of the image. Zoom in to the needs of the desktop background.

4. Before the user wants to set a part of a large picture as the desktop background, it is necessary to use the image editing software to cut the picture and then set it to the desktop background, but when the picture part of the display is adjusted again, the same Operation, cumbersome steps make the user lose interest in setting the background image of the desktop.

It can be seen that the existing processing method of the desktop background image has the problem that the operation is inconvenient and the desktop background image display effect cannot be well handled.

Summary of the invention

The technical problem to be solved by the present invention is to provide a method and a device for processing a desktop background and an interface system of an operating system desktop, so as to solve the problem in the prior art that a menu or a dialog box is required to complete the operation and the display effect cannot be quickly controlled. problem.

detailed description

The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

The embodiments of the present invention can be applied to a computer device using the Windows XP operating system, but are not limited thereto, and those skilled in the art will readily understand that the present invention can be applied to any computer device having a display and a processor. Such as PDA, mobile phone, digital TV set-top box, laptop or PC.

Take Windows XP as an example. A typical layout of the desktop is shown in Figure 1, including the desktop window.

201. The desktop background 202, the shortcut 203, the shortcut area 204, and the blank area 205 also include a task bar 206 for task scheduling and switching, and a "Start" button 207 for calling up more startup links in the menu mode. The desktop background 202 is a picture overlaid on the desktop window 201 (the picture can also be cancelled by the user and replaced with a monochrome background).

Some operating systems also support multi-desktop switching. For example, a Linux operating system has four desktops that can be switched by the user. Although Windows XP does not directly provide multiple desktops, it provides a programming interface for creating multiple desktops.

In addition, there is a type of virtual desktop software in third-party software that is characterized by the ability to create multiple desktops. Similar to the purpose of multiple desktops provided by the operating system, the main function of virtual desktops is to provide more flexible application shortcut group management to suit different work environments. A virtual desktop may be a stand-alone, stand-alone alternative to operating system desktop control, or a functional extension based on existing operating system desktop features.

The following describes the process of subclassing the default desktop of the Windows XP operating system and implementing the present invention to achieve a visual background display without a visual interface.

In the existing Windows XP operating system, the desktop does not provide a response to the selection operation and scrolling operation of the mouse in the background area of the desktop. To implement the present invention, the response process of the message can be taken over by the desktop window, and then the code is used according to the mouse. The operation responds by controlling the output of the desktop. The invention completes the interception of the human-computer interaction message of the desktop by subclassing the desktop, and after analyzing and filtering the message, calling the API (application programming interface) to implement the table when receiving the specific message. The display of content and the control of the desktop display process. The invention also completes the control of the desktop by sub-process sub-classification of the desktop window, intercepts the message of the desktop window, and realizes display control and interactive operation on the background area of the desktop. The subclassing flowchart of the desktop is as shown in FIG. 2, which specifically includes: first installing a system hook function, and sending a subclassing message to the resource manager, the message triggering a system hook function, and the operating system automatically includes a DLL containing a hook function (dynamic The link library is loaded into the resource manager process, and then the hook function is executed, and the system hook function responds to the message to complete the subclassing of the desktop window. In order to avoid affecting system performance, after completing the subclassing operation, you can increase the DLL reference to keep the DLL in the resource manager process and cancel the system hook. This completes the interception of the desktop message and the integration of the processing code with the desktop. The processing code can receive the operation information of the user's keyboard, mouse or other computer pointing device on the desktop and respond to the corresponding message.

One of the methods for obtaining the operation information of the pointing device on the desktop in the Windows operating system is not limited to the present invention. The specific implementation may also be implemented by other means, such as creating a pointing device. It is possible to receive information about the object of the operation information and periodically detect the operation information of the pointing device. The implementation method may be different on different operating systems, and for the operating system developer, the implementation method may be more direct.

Referring to FIG. 3, it is a flowchart of Embodiment 1 of the method of the present invention, which includes:

Step 401: Receive a command issued by a computer human-machine interaction device.

The command is directly issued by the computer human-computer interaction device, and is an action command directly sent by the computer human-computer interaction device, for example, a direct command such as a button press, a double click, a cursor position movement or a wheel rotation, and is not a human-computer interaction by a computer. The function command issued by the control by clicking the button, selection box and other related controls displayed on the screen. In the subsequent steps, the desktop background image is processed according to the direct command, which reduces the steps of the user operation, saves the user time, and improves the operation efficiency.

The human-machine interaction device is an input device connected to a computing device, such as a keyboard, a mouse, a joystick, a trackball, a touch screen, a stylus or a wireless remote control device; a command for inputting a user. The command may be a specific button, or a combination of specific buttons, or a scrolling of a device such as a scroll wheel or a trackball or a combination thereof with a specific button, for example, Ait t of the keyboard or swft and Ctrl buttons. The combination can also be a combination of Ctrl and → buttons, or a frame selection action by holding down the left mouse button to move the mouse.

Step 402: Process the desktop background image directly according to the command. After performing the subclassing operation on the windows XP desktop window as described above, the desktop system can intercept the direct command issued by the computer human-computer interaction device (such as a mouse) on the desktop, and according to the content of the command, the trigger program code is pre- The defined processing method is to process the desktop background image. In this step, the subsequent processing is not required to be converted into a function instruction by converting the operation message of the control displayed on the screen, and the desktop background image can be directly processed according to the command and the processing effect is immediately reflected on the desktop background.

The specific process of step 402 may be: acquiring a current background image of the desktop, processing the desktop background image according to the specific function of the instruction, and displaying the processed desktop background image on the desktop. The result of the processing is to change the appearance of the desktop display. Here, it is possible to create a buffer area in the memory, copy the current desktop display content data into the buffer area, directly process the data of the buffer area, and then copy the data back to the current desktop background after processing; or directly The method of processing the image data of the desktop background. Those skilled in the art can understand that the method that can directly process the desktop background display content data is a method that can be adopted by the present invention.

Preferably, the processing the desktop background image may be to zoom the desktop background image. The zooming process can be implemented by the following method: after obtaining the zoom instruction sent by the user through the computer human-machine interaction device, the current background image data of the desktop is read, and the zoom ratio is calculated according to the instruction, and the background image of the desktop is enlarged or reduced. When the desktop background image is scaled, the bitmap processing interface provided by the system can be called to process, or the processing function can be further processed for processing. The specific implementation process is easily understood by those skilled in the art and will not be described again.

Preferably, according to the command, a zoom area is determined, and the zoom area is a part of an entire desktop background image or a desktop background image.

The command issued by the computer human-machine interaction device determines the range of the zoom area. When the zoom area is not selected in the command, the zoom area may be considered as the range of the entire desktop background image. When the command includes a selection parameter for the zoom area, Get the selected zoom area, which is part of the entire desktop background image.

Preferably, according to the command, a zoom center is determined, where the zoom center is a desktop center, a zoom center or a location of a computer human-machine interaction device cursor or a given coordinate position.

The present invention provides a variety of ways to dynamically scale the desktop background. According to the zoom position of the desktop background image, it can be divided into the desktop background centered zoom and according to the position of the cursor of the computer human-computer interaction device. Put it. According to the different commands, when the desktop background image is zoomed, the zoom center is the center of the desktop, and the center position of the image remains at the center of the desktop during the zooming process; when the position of the cursor of the computer human-computer interaction device is zoomed The zoom center is the position of the cursor. During the zooming process, the image position of the cursor position remains unchanged on the desktop. When the local area selected by the user is zoomed, the zoom center is the center of the local area; the zoom center can also be any The given coordinate position.

When zooming, the zoom action can be triggered by a predefined action, such as scrolling up with the mouse wheel or '+, the button triggers the zooming of the desktop background, scrolling down with the mouse wheel or '-, the button triggers the zooming of the desktop background. In the dynamic zooming process, the zooming process is as shown in FIG. 4. The specific steps are: responding to the zooming instruction, determining whether it is an enlarged instruction, and if so, obtaining an amplification factor, if not, obtaining a reduction factor, according to the set each zooming operation The scaling factor and the current drawing size (wd, hd) calculate the scaled drawing size (ws, hs), get the width W and height h of the desktop window, calculate the drawing area of the desktop background, and display the desktop background. Ws represents the drawing width of the background image after scaling. It can be calculated by multiplying the current drawing width of the background image by the scaling factor. hs is the height of the background image after scaling. It can be calculated by multiplying the current drawing height of the background image by the scaling factor. When the zoom operation is performed, the drawing start coordinates and drawing area of the picture may actually exceed the visible range of the desktop, but this does not affect the final display result.

An optional algorithm for calculating the drawing area of the desktop background is given below:

Assume that the top left corner of the desktop window is the coordinate origin. When zooming with a point as the zoom center, the position of the zoom center on the desktop window remains unchanged before and after zooming. Referring to FIG. 5, the width of the desktop window is w, the height is h, the drawing width of the current desktop background image is wd, the drawing height is hd, and 801 represents the position of the zoom center, and the coordinates in the desktop window are (xp, yp). The coordinates of the top left corner of the desktop background image on the desktop window are (X, y). Focus on the 801 as the center, and scale the desktop background image. Set the zoom factor to s. The calculation formula for the drawing area of the desktop background image after scaling is as follows: xs = xp - sx(xp - X)

Ys = yp - sx(yp - y)

Ws = sxwd

Hs = sxhd

Xs: The horizontal coordinate of the top left corner of the scaled desktop background image relative to the top left corner of the desktop window. Ys: The vertical coordinate of the top left corner of the zoomed desktop background image relative to the upper left corner of the desktop window. Ws: The drawing width of the scaled desktop background image.

Hs: The height of the zoomed desktop background image.

When the mouse position is used as the zoom center, the above (xp, yp) is the coordinates of the mouse on the desktop window. When using the desktop background centering zoom mode, the zoom center, the center of the desktop window, and the background image center are coincident. According to the above principle, the calculation formula of the zoom area is:

Ws = sxwd

Hs = sxhd

Xs =(w-ws)/2

Ys = (h-hs)/2

After calculating the above data, the desktop background image is stretched and displayed at coordinates (xs, ys) and coordinates (xs).

The rectangular area between +ws, ys +hs ) completes the scaling operation.

Preferably, the range of the zoom area is adjusted such that the aspect ratio is close to the aspect ratio of the desktop. In this embodiment, the aspect ratio of the zoom area is equal to the aspect ratio of the desktop. For example, if the similarity coefficient is set to 0.8, then a 4:3=1.333, 5:4=1.25 is assumed, then the similarity is larger and the similarity is smaller. The similarity is 1.25/1.333>0.8, indicating similarity. . The value of the similarity coefficient of the specific implementation is determined as needed. .

When the local area of the selected desktop background image is zoomed, the selected local area can be reduced or enlarged, and the local area can be directly enlarged into the desktop background. During the area selection operation, the selection range is wide. The height ratio is generally different from the aspect ratio of the desktop. Before zooming in on the area, the range of the area needs to be adjusted so that the aspect ratio of the current selected area is close to the aspect ratio of the desktop. In this embodiment, the width of the zoom area is wide. The height ratio is equal to the width and height of the desktop.

The height and width of the selection range are hsel, wsel, the height and width of the desktop are hdesk, wdesk, respectively, if hsel/wsel> hdesk/wdesk, the target is full of desktops in the selected range, and the scale is hdesk/hsel. Adjust the width of the selection range according to the aspect ratio of the desktop, so that the aspect ratio of the selection range is close to the aspect ratio of the desktop. In this embodiment, the aspect ratio of the zoom area is equal to the aspect ratio of the desktop, that is, hsel/wsel = hdesk/wdesk, so that the width of the adjusted selection range is equal to wsel=hsel*wdesk/hdesk;.

If hsel/wsel<= hdesk/wdesk, the horizontal extent of the range is filled with the desktop, the scaling is wdesk/wsel, and the height of the selection range is adjusted according to the aspect ratio of the desktop, so that the aspect ratio of the selection range is close to the aspect ratio of the desktop. Take the example of equality, that is, make hsel/wsel = hdesk/wdesk, so that the adjustment is pushed out. The height of the post selection range is equal to hsel = wsel *hdesk/wdesk.

When zooming, it may be necessary to synchronize the movement of the zoom area. The center of the target area where the picture is moved is called the target center. Usually, the target center is the center of the desktop. In a continuous zooming process, the target center can follow the zoom effect. The need to change dynamically.

Preferably, when the center of the zoom area and the target center do not coincide, the zoom area is moved until its center coincides with the target center.

When you select a local area of the desktop background image for zooming, you can move the center of the local area to the center of the desktop. The target center is the center of the desktop, which centers it and zooms in and fills the desktop background.

Referring to FIG. 6a, it is a flowchart of zooming in a local area of a desktop background image according to the present invention. The specific steps are: responding to a mouse frame selection operation, obtaining a current frame selection range, and determining whether a shortcut is selected, if not, according to the above method. Adjust the frame selection range, and calculate the magnification factor, and enlarge the image display within the frame selection range. If yes, send the message back to the system without processing. Referring to FIG. 6b, which is an example of the selection of the frame selection enlargement area of the present invention, the arm portion of the portrait is selected by using the mouse on the desktop background; see FIG. 6c, which is an example of the selection of the frame selection enlargement area of the present invention, and the arm portion of the portrait is Zoom in to become the desktop background.

Preferably, the processing the desktop background image may also be: moving the desktop background image.

Moving the desktop background image may be implemented by pre-defining an operation instruction that triggers the movement of the desktop background, such as pressing a keyboard's direction key to move the command, and when intercepting the direction key pressed command, acquiring the desktop background. Picture, after moving the display position of the desktop background image, redisplay in the desktop background. Here, it is also possible to obtain the display scale of the current background image, the display position, and the location of the original file of the desktop background image, obtain the image from the file, and move the display position to display on the desktop background.

Preferably, according to the command, the step size of the movement is determined, and the step size is a preset value or a cursor movement distance of the computer human-machine interaction device.

In the process of implementing the movement, the value of the step size of each movement may be preset, and each time the movement is performed, only a fixed distance is moved, or the moving distance of the cursor of the computer human-computer interaction device in the intercepted command may be moved. Step size. For example, when you get the keyboard's arrow keys to press the command, put the desktop background image After moving according to the preset fixed step size, when the command of the middle button of the mouse is pressed and the mouse cursor is moved to the new position, the background image of the desktop is moved according to the direction of the mouse movement, and the mouse is pressed when the middle button is pressed. The distance between the position of the cursor and the new position of the mouse cursor.

Referring to FIG. 7, which is a flowchart of moving a desktop background image according to the present invention, the specific steps are as follows: responding to a mouse button press message, recording the mouse position A at this time; responding to the mouse movement message, tracking the mouse movement position B; Determine whether the middle button of the mouse is kept pressed. If the middle button of the mouse has been released, the moving operation is ended. Otherwise, the current position B of the mouse is obtained, and the distance between the current position B of the mouse and the position A is calculated to obtain the offset of the desktop background to be moved. Use this offset to update the position of the desktop background, refresh the display of the desktop, and complete a move.

Preferably, the movement is repeatedly performed until the desktop background image in the opposite direction of the movement exceeds the desktop background portion and is gradually displayed on the desktop background.

When the background image of the desktop is large and exceeds the visible range of the desktop, you can browse the image beyond the desktop by automatically repeating the movement of the fixed step. For example, a wide landscape picture is displayed on the desktop background. The parts on both sides cannot be displayed. At this time, the user can display by moving the picture, each time moving a fixed step or using the mouse to move, but the user needs to perform multiple operations to gradually display the part beyond the desktop on the desktop. On the background, the user is inconvenient to use. This embodiment can provide a method for automatically panning the background image of the desktop until the end of the image is displayed. The "Ctrl-→" key combination can be defined as a command for automatically moving the desktop background image to the right. When the "Ctrl-→" key combination is pressed, the current desktop display position is obtained. After moving the picture according to the preset step size, it is displayed on the desktop background, and the previous steps are repeated until the leftmost picture is gradually displayed on the screen. Here, the automatic movement can also be stopped by the user's stop movement command, and the position of the background image of the desktop image desired by the user can be conveniently located.

Preferably, the processing of the desktop background image may also be performed by adding a special effect to the desktop background image.

The processing of the background image can also be a special effect, for example, when the background image of the desktop is a portrait, the portrait can be framed, or when the landscape is landscaped, the color transformation processing can be performed to make the desktop background image The display is more beautiful.

Preferably, the special effect is a picture frame modification or a picture pixel level conversion process.

The special effects include picture frame decoration, picture pixel level transformation processing, such as lighting effects, relief, Tone adjustment, distortion, etc. For example, by changing the background image to an embossed effect, or by adding a lighting effect to the desktop background. The following describes an implementation method for processing a desktop background image as an embossed effect, and other effects are not enumerated one by one.

The image can eventually be converted into a two-dimensional array of pixels that record the color information for each pixel in the image. In Windows, the color is defined by the saturation of the three colors red, green, and blue, referred to as the three primary colors. The special effect processing of the image can be realized by changing the color value of some or all of the pixels of the image by a certain algorithm. The embossing effect is that only the changed part of the image is highlighted, and the same color part is faded, so that the image has a sense of depth, thereby achieving the relief effect. The formula of the relief algorithm is as follows: Rl=(R-r)+C

Gl=(G-g) + C

Bl=(B-b)+ C

Where R, G, B are the primary color values of red, green and blue corresponding to the pixel, r, g, b are the primary colors of red, green and blue of the adjacent pixels of the point, and C is the threshold for determining the relief effect, and the value is The effect between 100 ~ 150) is better, among which the three primary color values after R1, G1 and B1 transformation.

The algorithm adopted in this embodiment is that the value of the pixel to be processed is the difference between the pixel and the other pixel on the diagonal, so that only the color change region will appear color, and the color dull region has almost zero difference. Turning black, you can add some brightness by adding a constant C.

Referring to FIG. 8, which is a flowchart of the embossing effect processing on the desktop background image, the specific steps are as follows:

The execution of the embossing effect is triggered by an operation, and first an in-memory bitmap is created for saving the processed image. Then, the cache content of the current background image is obtained, and each pixel is looped from the upper left corner to obtain the pixel value of the current position (i, j), which is decomposed into R, G, B, and represents the red, green, and blue primary color values corresponding to the pixel. . The pixel value of the diagonal (i+l, j+l) of the current position is obtained, and is decomposed into r, g, b, which represent the three primary color values of red, green and blue corresponding to the pixel. The transformed three primary color values are calculated by the following formula.

Rl=(R-r)+C

Gl=(G-g)+ C

Bl=(B-b)+ C

C is a constant, and the transformed three primary color values R1, G1, and B1 are calculated. Combine R1, G1, and B1 into pixel values and set them to (i, j) of the memory bitmap. Complete the loop and set the current desktop display background to Built memory bitmap. Refresh the desktop and complete the setup.

Preferably, the method further includes: acquiring and saving display control parameters of the desktop background, wherein the display control parameters are used to control display of the desktop background.

When the user changes the background image of the desktop to other pictures, in order to achieve the best display effect, the process of repeated movement and zooming is required, the steps are numerous, the operation efficiency is low, and the user loses the interest in adjusting the background image of the desktop. In order to solve this problem, the present invention also provides a method of storing the background control parameter of the desktop and a method of restoring the display effect of the background image of the desktop. After the processing of the desktop background image reaches the required realistic effect, the display control parameter of the current desktop background is saved when a specific command is obtained, the desktop background changes, or at a specific time, and the display control parameter content may include: a desktop background image The corresponding image file's unique identifier, storage location, desktop background image zoom ratio, display position on the desktop, special effects settings, etc., when the desktop background image is repeatedly used as the desktop background, the system according to the corresponding image file The unique identifier finds the latest one among the saved multiple display control parameters. According to the display control parameter, the last display effect is automatically reproduced, and the repeated operation of the user is avoided. For the same desktop background image, multiple display control parameters can be saved, which represent different display effects.

Display control parameters can be stored anywhere, typically in a local file, in a database, on a registry, or on a remote server. The unique identifier is a piece of data that is much smaller than the content of the picture itself, and the fingerprint information of the picture file can be used as the unique identifier. The fingerprint information of the picture file is an identifier generated by each algorithm according to the content, and the same content is generated according to the content; The image file, regardless of whether the physical location of the storage is the same, will produce the same unique identifier; the image files of different contents, even if the names are the same, the unique identifiers generated are different.

There are several ways to generate a unique identifier based on the content of the file. A common method is to use a hash of the contents of the file. A hash function maps a binary string of arbitrary length to a small binary string of fixed length. The hash function has an attribute that it is not computationally likely to find two different input values that are hashed to the same value; that is, the hash values of the two sets of data will only be matched if the corresponding data also matches. match. A small amount of change in data can produce unpredictable large changes in the hash value.

There are many mature algorithms for calculating hash values in actual use. These algorithms are not only highly efficient, but the probability of different raw data calculating the same hash value is extremely low, so the hash value can be regarded as the fingerprint of the original data. Commonly used hash algorithms include: MD2, MD4, MD5, SHA, and so on. Preferably, the method further comprises: reading display control parameters; displaying a desktop background according to the read display control parameters.

Each display control parameter can be used to reproduce the display effect of the desktop background. According to the received commands, the display control parameters read here can be read in two ways, one is according to the current desktop background image. The unique identifier of the image file is used to select the display control parameter, and the display control parameters associated with the same image file are sorted by time. If the current display effect has been saved, the previous one is read, and if the current one is not saved, the read is performed. The latest one; another way is to sort all the display control parameters by time and read the previous one in sequence. After the display control parameters are obtained, the image file is obtained according to the parameters saved in the display control parameters, and the desktop background is displayed according to the display scale, display position, and special effects in the parameters.

Preferably, the computer human-machine interaction device may be a keyboard, a mouse, a joystick, a trackball, a touch screen, a stylus or a wireless remote control device, and is not limited to these devices. These computer pointing devices can send operating instructions to the computer device through the communication interface to implement control operations on the computer device, and the most widely used one is a keyboard or a mouse.

Preferably, the command issued by the computer human-machine interaction device may be: clicking a computer human-computer interaction device button issued on the desktop, double-clicking the computer human-computer interaction device, scrolling the scroll wheel of the computer pointing device, and moving the cursor of the computer pointing device Tracks, desktop area selections or specific keys pressed on the keyboard, and combinations of them. The command is issued by a computer pointing device on the desktop of the computer device, that is, a command issued on the desktop background image when the desktop background image is displayed, for example, when the human-computer interaction device is a mouse, the desktop is selected. Background image, use the mouse to issue a single double-click or scroll wheel command, use these commands to directly process the desktop background image, instead of displaying controls such as buttons on the desktop, indirectly by the mouse selection button and other controls; when the human-computer interaction device When the keyboard is displayed, a specific combination key command can be issued in the case of displaying the desktop background image, and the desktop background image can be directly processed according to the command, and the other interfaces are not opened for operation.

Referring to Figure 9, there is shown an operational position map of the desktop background automatic panning of the present invention as an extension of the mobile desktop background of the present invention. It can be displayed on the desktop, the operation location map includes the central area 300, and eight operational response areas are distributed in eight directions around the central area 300: the left area 301, the upper area 302, the right area 303, the lower area 304, and the upper left area 305. , the upper right corner area 306, the lower right corner area 307, and the lower left corner area 308. The operation position map can be triggered by an operation, such as a mouse or button message, or automatically displayed when certain conditions are met, such as when it is detected that the current desktop background display portion is beyond the screen. Using the mouse to click on the areas of operations 301 through 308, the desktop background automatically moves in the direction represented by the current operating area until all portions of the desktop background beyond the desktop are displayed on the desktop or select to stop automatic movement. Automatic movement selects smooth movement or interval movement.

It should be noted that the operation position map is not a control such as a button displayed on the desktop, but only provides a prompt function for providing an operation position, and does not convert the command issued by the mouse like the control, so it may not be displayed. As long as the mouse clicks on a specific location, the desktop background image is automatically moved.

The automatic mobile operator interface can also be replaced with other operational response methods. Preferably, the command to automatically move the operator interface is replaced with a mouse action action. For example, press the middle mouse button and note the mouse position at this time. This position represents the 300 area in Figure 9. With this position as the center, 8 virtual mouse movement response areas or 8 directions are formed in the surrounding 8 directions. Corresponding to the 301 to 308 area or in Fig. 7, respectively. The 8 virtual mouse movement response areas are not necessarily embodied by a specific interface, but are prompted by changing the graphical display of the mouse when the mouse moves to the area, and the desktop background automatically moves along the direction represented by the current area until the desktop The part of the background that exceeds the desktop is displayed on the desktop or you choose to stop automatic movement.

Referring to FIG. 10, a flow of automatically moving a desktop background in response to a mouse operation is illustrated, which specifically includes: responding to a mouse button press message, recording a position of the mouse, and displaying a ready to move mark centered on the position, responding to a mouse movement message, according to The position of the mouse movement calculates the current area, determines whether it needs to move in the direction of the area, and if not, continues to monitor other messages of the mouse. If yes, set the graphical representation of the mouse pointer according to the position of the area, according to the distance from the center point. Set the amount of translation each time, set the movement interval time, start the automatic panning timer, adjust the position of the background in the automatic panning timer, and refresh the display to judge the automatic panning operation. If not, return to the previous step, and if so, turn off the timing. , cancel the display of the panning flag.

For wide landscape photos, use the vertical full desktop to activate the horizontal pan function, which can improve the high-resolution picture browsing experience. It is convenient to automatically browse the whole picture from left to right or right to left, because no manual control is needed. It simulates the observation process of the human eye and can improve the user's experience.

As an extension of the mobile desktop background of the present invention, in actual use, it is possible to specify a room Multiple display control parameters of the same background image are continuously transferred, and the display effect of the desktop background is reproduced in accordance with each display control parameter. In this way, the continuous transformation effect of the same picture can be automatically displayed according to a preset display scheme.

When the effect of the transformation is continuously displayed, it is also possible to switch by the method of dynamic gradation in the case of adjacent effect transformation. For example, the transformation of the picture center and the image scale can be smoothly and automatically interpolated, or it can be gradually disappeared, which makes the user feel smooth when using, and improves the user experience.

Other ways of defining the operational instructions of the present invention are also possible. For example, different actions can be performed according to different instructions of the human-computer interaction device. Taking the mouse as an example, the user selects from the upper left to the lower right frame, and the user wants to enlarge an area from the upper right to the lower left frame, and the user wants to go back. The desktop background display state when the control parameters are displayed is saved. In this way, each display control parameter can be regarded as a snapshot for saving the desktop background display effect; when the mouse is moved, the cursor is moved from the lower left to the upper right, The user wants to switch to the next desktop background image, from bottom right to top left, on behalf of the user wishing to switch to the previous desktop background image.

The invention can also use the operation instruction of the mouse pointer to a specific area on the screen to complete different operations, preferably defining the command in a 9-square grid manner, and virtually defining the blank area of the desktop after setting the desktop background into the 9-square grid area. Specify the corresponding operation for the mouse operation message in each area, for example: Double-click on the right grid to switch to the next desktop background image, double-click in the left grid to switch to the previous desktop background image, double-click in the middle grid to fill in the Switch between the previous snapshots, double-click to switch to the previous snapshot in the upper grid, and double-click to switch to the next snapshot in the lower grid. This has the advantage of providing a rich, fast adjustment of the desktop background without the need for additional control interfaces. As an extension, similar "4 squares", "6 squares" or other irregular area definitions may be specified, and when the boundaries of these areas do not display or provide visual features, that is, the instruction partitions of the present invention.

Preferably, the computer human-machine interaction device may be a keyboard, a mouse, a joystick, a trackball, a touch screen, a stylus or a wireless remote control device, and is not limited to these devices. These computer pointing devices can send operational commands to the computer device through the communication interface to implement control operations on the computer device, and the most widely used one is a keyboard or a mouse.

Preferably, the apparatus may further include: two or more of a scaling processing unit, a movement processing unit, a special effect processing unit, and a switching processing unit. The specific implementation process is similar to the implementation process of the apparatus including the scaling processing unit, and is not mentioned here.

Preferably, the device may further include: an instruction partition processing unit, configured to receive a computer man-machine The command sent by the interaction device determines, according to the command, an instruction partition where the cursor is located when the human-machine interaction device issues an instruction, and executes an instruction preset by the instruction partition. The command includes at least the following:: clicking a computer human-computer interaction device button on the desktop, double-clicking the computer human-computer interaction device, scrolling the scroll wheel of the computer pointing device, moving the track of the computer pointing device cursor, and the desktop area Frame or press a specific key on the keyboard, and a combination of them. Unlike the usual buttons and toolbar icons that always need to provide a visual boundary, the boundaries of the instruction partition of the present invention do not display or provide visual features when the pointing device enters the corresponding instruction partition.

The specific implementation process is illustrated by the following example. In this embodiment, the command is a mouse command, but is not limited thereto. Other devices or areas for issuing commands are similar to the mouse; In this embodiment, the backup desktop background image has three, and the desktop background image list including the index and the path is as shown in Table 1 (that is, the wallpaper list):

Table 1

The desktop instruction partition list is as shown in FIG. 14. The desktop instruction partition list is a method for dividing the area according to the rule, for example, the right side of the desktop is divided into four areas (which can be arbitrarily divided), in order not to hinder the user's use, the instruction name and the area division in the desktop The line is invisible during normal use. Of course, the dividing line or boundary of the display area can be set at the beginning of guiding the user. Assume that the current desktop background image has an index of n in the list of desktop instruction partitions. 1501 starts a shortcut for the application, 1502 is the instruction partition, 1503 is the instruction partition split line, 1504 is the operation guide prompt icon of the instruction partition 3, and 1505 is the instruction partition boundary.

The instruction response definition of each instruction partition, that is, the mapping relationship between the instruction partition on the desktop and the command to be executed after receiving a specific mouse instruction (that is, the desktop instruction partition list) is as follows:

The first command partition is double-clicked to enlarge the current wallpaper 20%;

The second command partition is double-clicked to reduce the current wallpaper 20%;

After the third command partition is double-clicked, the n-1th picture in the wallpaper list is set as the desktop wallpaper; the fourth command partition is set to the desktop wallpaper after the mouse double click, and the n+1th picture in the wallpaper list is set. In addition, you can also set other command partitions, such as setting the 5th command partition, returning the current wallpaper to the default size after double-clicking the mouse, etc., no longer - for example.

The instruction partition and its boundary and split line usually only have specific coordinate attributes to determine the area where the mouse cursor is located. The split line is also the element that constitutes the boundary of the command area. The difference from the usual button and toolbar icons is that the boundary of the instruction partition of the present invention does not display or provide visual features when the pointing device enters or exits the corresponding instruction partition, and may also be other visualization features. For example, a partial hint icon similar to 1504 can avoid affecting the display effect of the entire desktop wallpaper. The 1504 guide prompt icon is optional and can be briefly displayed after the mouse enters the area to serve as a prompt, the prompt icon and the regular command. The difference between a button or a command icon is that it does not require a response command, and its size is usually smaller than the corresponding instruction partition size, and is not necessarily located within the instruction partition. The arrows in Fig. 15 suggest that the user will switch the wallpaper to the previous picture in the wallpaper list after double-clicking in the area. The coordinate quantization and area determination of the instruction partition boundary should be easily completed by those skilled in the art, and is not specific here. Expand the description. After making the above settings, the following describes its response process:

Assume that the current wallpaper is the second one, which is C:\photo\2.jpg. Detects the operation command of the mouse. If it detects that the mouse double-clicks the mouse in the first command partition, it performs the operation of enlarging the current wallpaper by 20%. If it detects that the mouse double-clicks the mouse in the second command partition, the current wallpaper is reduced by 20 % operation, if it detects that the mouse double-clicks the mouse in the 3rd command partition, it performs the operation of setting the first picture "C:\photo\LJpg" as the desktop wallpaper, if it detects that the mouse is double-clicked in the 4th command area When the mouse is over, the operation of setting the third picture, "C:\photo\3.jpg", to the desktop wallpaper is performed.

In the above real-time example, the desktop icons are schematic diagrams of the instruction partitions displayed on the desktop. For the present invention, a schematic diagram of the instruction partitions on the desktop when the desktop icons are hidden is also provided, as shown in FIG.

As shown in FIG. 15, the method includes: 1601 is an instruction partition, 1602 is an instruction partition dividing line, and 1603 is an operation guidance prompt icon of the instruction partition 3 (such as closing all active applications or clicking a mouse in this area to switch to the next A desktop background image, etc.), 1604 is the instruction partition boundary, and the application is launched by clicking a mouse on different areas of the desktop. Different response definitions can be established for different human-computer interaction device operation actions in one instruction partition. For example, the first instruction partitions respectively establish response definitions for mouse clicks and double-clicks. This embodiment also adopts an irregular area division method. In this embodiment, the application shortcut is hidden, and the middle of the desktop is divided into three areas, each instruction partition. The command response is defined as follows:

The first instruction partition instruction 1 starts the mail client after double-clicking the mouse;

The first instruction partition instruction 2—after clicking the mouse, start the Internet browser;

After the second command partition is clicked by a mouse, the office component word is started;

After the third command partition is clicked, all active applications are closed.

Detecting the operation instruction of the mouse, if detecting that the mouse double-clicks the mouse in the first instruction partition, executing the startup instruction of the mail client; if it detects that the mouse is clicked in the first instruction partition, the Internet browser is started; if the mouse is detected When the second instruction partition is clicked, the office component word is started; if it is detected that the mouse is clicked in the third instruction partition, it is only necessary to close all application operations.

The operation prompt of this embodiment adopts a popular mouse tracking prompt form, and the operation prompt is activated when the mouse enters the instruction partition for a short time. In the specific implementation, the size of the instruction partition and its position can be transformed according to actual needs. In the practice of the present invention, the number of instruction partitions, the size of the boundary, and the choice of the mode of operation are all variable.

The instruction partition can be divided according to the actual needs. For the specific implementation process, refer to the foregoing embodiment, and details are not described herein.

It should be noted that the processing unit in the apparatus may further include: at least two units of the scaling processing unit, the mobile processing unit, and the special effect processing unit switching processing unit. The functions and functions of the various units are described above, and are not described here.

In addition, the present invention further provides an interface system of an operating system desktop, and a block diagram of an embodiment thereof is shown in FIG. 16, and includes: a background picture display unit 1701, a shortcut processing unit 1702, a command receiving unit 1703, and a processing unit 1705. The processing unit 1705 further includes: a scaling processing unit 17051, a movement processing unit 17052, a special effect processing unit 17053, and a switching processing unit 17054. The figure includes four units as an example, and may also include at least one of the four units. .

The background image display unit 1701 serves as a main object of the desktop, covering the main area of the entire desktop, and functions to beautify the desktop; the shortcut processing unit 1702 is responsible for managing the application shortcut icon and the corresponding program path, on the background. The application shortcut icon is displayed, and the corresponding program is started according to the user instruction; in addition, the menu for starting the application can also be regarded as a shortcut. The command receiving unit 1703 is configured to receive a command sent by a computer human-machine interaction device, and identify a background image processing command; the processing unit 1705 is configured to use the background image The processing command directly processes the background image in the background image display unit, and the processing result is drawn by the processing unit or the background image display unit onto the desktop background.

It is assumed that the command processing unit presets to push the mouse wheel forward to enlarge the command or instruction in the blank area of the desktop (the large area covered by the application shortcut), and the processing unit 1705 determines the cursor position when receiving the mouse operation command or instruction. Whether it is located in the blank area of the desktop and whether the mouse wheel is pushed forward, if the predetermined condition is satisfied, the processing unit 1705 completes the enlargement operation of the background picture.

Preferably, the processing unit 1705 includes at least one of the following: a scaling processing unit 17051, a mobile processing unit 17052, a special effect processing unit 17053, and a switching processing unit 17504. The scaling processing unit 17051 is configured to perform a scaling process on the desktop background image according to the command; the mobile processing unit 17052 is configured to perform a mobile processing on the desktop background image according to the command; The unit 17053 is configured to perform special effect processing on the desktop background image according to the command, where the special effect processing refers to a process of modifying a picture frame or converting a picture pixel level. The switching processing unit 17504 is configured to directly select a target desktop background image from the wallpaper list according to the command, and draw the target desktop background image to the desktop. It can also be used to directly switch the desktop background image according to the command and the preset mapping relationship.

Preferably, the embodiment of the present invention may further include: an instruction partition processing unit 1704, where the instruction partition processing unit 1704 is configured to receive a command sent by the computer human-machine interaction device, and determine, according to the command, the human-machine interaction device to issue an instruction. The instruction partition where the cursor is located, and executes the instruction preset by the instruction partition.

The instruction partition processing unit manages the setting of the preset area, including the boundary of the area and the issuance of the operation instruction and the corresponding command, for example, the instruction unit management is as follows: occupying the screen 1/8 range in the lower right corner of the screen The click of the mouse command corresponds to shrinking the desktop background by 20%, and the double-clicking mouse command in the upper right corner of the screen in the range of 1/8 of the screen corresponds to enlarging the desktop background by 20%. When the mouse is clicked on the screen, the lower right corner occupies the screen. When clicked within the range of 1/8, the command unit will issue a command to enlarge the desktop by 20%, which is executed by the desktop background processing unit. The instruction partition processing technique can also be used for application startup when a corresponding command for a particular region is preset to launch a particular application.

The operating system desktop interface system of the invention solves the problem that the existing desktop system does not support flexible adjustment The problem of the desktop background display effect improves the convenience and humanity of the interface. In another embodiment of the invention, the invention may be implemented using Windows ActiveDesktop technology. Windows XP ActiveDesktop provides a programming interface that allows the user to specify a web page as the desktop, and the background file needs to be entered when the background file is set. As far as ActiveDesktop itself is concerned, it actually provides a web container, with a web browser window embedded in the desktop or paving the entire desktop as the desktop background. The web page displayed in the browser window on the desktop background has the same characteristics as the ordinary web page. If you can have a hyperlink, you can click and so on.

In a solution for implementing the present invention by using ActiveDesktop technology, firstly, an ActiveDesktop interface method such as AddDesktopItem (adding a desktop item) is added to the desktop to display a desktop item of a specified webpage (a maximum effect can be achieved when maximizing). The web page is displayed on the desktop background, under the desktop shortcut, and integrated with the desktop. The image to be operated as the background of the desktop is displayed in the web page added to the desktop, and the built-in object in HTML (Hyper Text Link Markup Language) can be used to complete the zooming operation. Preferably, the related scaling operation can also be performed in a window or a dynamic webpage component on the webpage, and the window can be implemented in the webpage by using an HTML object simulation, such as an event response function provided by DHTML (Dynamic Hypertext Markup Language). In the webpage, scripts (such as JavaScript, etc.) are used to respond to operation events, control the zooming operation of the image, and dynamic webpage components such as flash can also be used to control the zooming operation of the image.

In order to make the operation mode of the picture on the webpage more suitable for the characteristics of the desktop background, the access to the desktop attribute can be added to the webpage component and the corresponding operation can be performed, for example, different response actions can be taken according to the relationship between the mouse position and the desktop shortcut: When the box is selected. It is possible to decide whether or not to perform a partial enlargement operation depending on whether or not a shortcut is selected.

In the solution for implementing the present invention by using the ActiveDesktop technology described above, the webpage can be automatically designated as the desktop background, and a function menu or button for calling the ActiveDesktop to designate the webpage as the desktop background is also provided on the webpage, when the user selects the menu. When the button is pressed, this page is designated as the desktop. Several different web pages are also available for users to choose from. The provided webpage can be saved in a local computer device or stored on a remote server, and the user can access the webpage through a network protocol (such as ftp or http).

The invention can also be applied to a mobile device or a digital TV set-top box and the like. Since there is no mouse device, the operation thereof is mainly operated by a keyboard or a remote controller, except for the operation instructions of the background operation thereof.
