Hereinafter, principle will be projected in conjunction with Fig. 2-screen shown in Fig. 7, a kind of image processing method of terminal provided by the embodiments of the present application is elaborated, as shown in figure 8, this method comprises:
S701, terminal connect external display device.
Illustratively, as shown in either figure in Fig. 2-Fig. 4, terminal can connect external display device by way of wired connection or wireless connection.
S702, the terminal determine subsequent display screen size when sending display picture to the external display device.
When terminal is connect with external display device, the display parameters such as the resolution ratio of external display device are can be detected in terminal, and then determine the display screen size of the subsequent display picture for needing to send to external display device.For example, external display device supports the image of 1080P format to show, then, terminal can determine that the display screen size of the subsequent display picture sent to external display device is the display picture of 1920 × 1080 resolution sizes corresponding with 1080P format.
For example, terminal can show " interface is welcome in large-size screen monitors projection " 117 as shown in Figure 2 or Figure 3 in its display screen.Meanwhile terminal can generate " welcome using large-size screen monitors project " signal language 121 for external display device, and by the prompt Language 121 is sent to external display device, so that external display device shows " welcoming to project using large-size screen monitors " signal language 121 as shown in Figure 2 or Figure 3.
Illustratively, by taking Fig. 2 as an example, terminal can show the operating instruction for carrying out large-size screen monitors projection function in " interface is welcome in large-size screen monitors projection " 117." skipping " option 113 in Fig. 2 in " interface is welcome in large-size screen monitors projection " 117 shown in terminal when the user clicks, or " interface is welcome in large-size screen monitors projection " 117 shown in Fig. 2 is shown after a certain period of time in terminal, terminal can show terminal interface 801 as shown in Figure 9 in the display screen of terminal, and large-size screen monitors interface 802 as shown in Figure 9 is shown in external display device according to the display screen size determined.
Wherein, external display device is when showing large-size screen monitors interface 802, if having selected the option of overscan in the system setting of external display device in advance, external display device can show the display content that interception is located at center 95% from the large-size screen monitors interface 802 that terminal is sent.At this time, as shown in Figure 10, the display picture of external display device is large-size screen monitors interface 802 ', some display contents when carrying out overscan due to external display device positioned at former 802 edge of large-size screen monitors interface are not extracted to, and incomplete display picture can be presented in the edge 803 after overscan on large-size screen monitors interface 802 '.
S703, external display device show the set interface of the display screen size for adjusting external display device.
In step S702, occur when in order to avoid terminal to external display device projection screen because showing the incomplete phenomenon of picture caused by overscan, connection is established in terminal and external display device, after the initialization procedure for completing external display device display, as shown in figure 11, external display device can be shown for adjusting its set interface 1001 for showing screen size.
Illustratively, user can execute right button operation by mouse on the large-size screen monitors interface 802 (or large-size screen monitors interface 802 ') of external display device, the right button operation that user inputs is sent to terminal by external display device, terminal is that external display device generates right-click menu, and the right-click menu is sent to external display device and is shown in response to right button operation.Wherein, may include in right-click menu for adjust display screen size screen setting options, then, when external display device detects that user chooses the screen setting options in above-mentioned right-click menu, can to terminal request show set interface 1001.After terminal receives the request of external display device, set interface 1001 shown in Figure 11 are generated for external display device, and be sent to external display device and shown.
Or as shown in figure 12, terminal can also pass into simulation key mouse function, and touch-control board interface 1101 as shown in figure 12 is shown in the display screen of terminal.In this way, working as touch-control board interface 1101 shown in 1104 hookup 12 of user's finger, and when touch-control board interface 1101 is mobile, the cursor that can control in large-size screen monitors interface 1102 shown in Figure 12 is accordingly moved.So, user can execute the selection operation of above-mentioned right button operation and above-mentioned screen setting options by touch-control board interface 1101 in external display device, triggering terminal is that external display device generates set interface 1001 shown in Figure 11, and is sent to external display device and is shown.
Or when terminal and after external display device successful connection, can automatic trigger terminal be that external display device generates set interface 1001 shown in Figure 11, and is sent to external display device and is shown, the embodiment of the present application does not do any restrictions to this.
Specifically, may include the size of multiple candidate screen sizes in the set interface 1001.As shown in figure 11, it include three kinds of candidate screen sizes in set interface 1001, one is the full screen pictures sizes 1101 that display picture is full of screen, and one is the moderate screen sizes 1102 that display picture accounts for screen 95%, and there are also one is the smaller screen sizes 1103 that display picture accounts for screen 85%.
Also, the picture of each candidate screen size still as shown in figure 11, is also respectively illustrated in set interface 1001 Face preview effect.Wherein, each width picture preview effect can be the preview effect that picture is arbitrarily shown when external display device does not do overscan processing, it is also possible to carry out the preview effect after overscan to arbitrarily display picture to the withdrawal ratio (such as 95% picture withdrawal ratio) of display picture default according to when overscan, the embodiment of the present application does not do this any restrictions.
For showing that picture accounts for the moderate screen size 1102 of screen 95%, terminal is when transmitting subsequent display picture to be shown (such as large-size screen monitors interface 802 shown in Fig. 9) to external display device, as shown in figure 13, it can be by the image (i.e. initially display picture) in large-size screen monitors interface 802 by original full screen pictures size reduction 95%, and the center at Image Adjusting to large-size screen monitors interface after reducing 95% is obtained into the target equal with picture size is initially shown and shows picture, at this time, target is shown in the target area for being located at center 95% in picture as the active area with essence display content.
So, after target is shown that picture is sent to external display device by terminal, still as shown in figure 13, external display device shows that picture carries out overscan, the i.e. picture at interception target display picture center 95% to the target received.In this way, the picture that external display device is truncated to just is the active area in target display picture, complete large-size screen monitors interface 802 can be shown in external display device at this time, overcomes the problems, such as to show that picture is incomplete caused by because of overscan.Therefore, as shown in figure 11, which can be prompted to user as recommended size.
In another example, for showing that picture accounts for the smaller screen size 1103 of screen 85%, terminal is when transmitting initial display picture to be shown to external display device (still by taking large-size screen monitors interface 802 shown in Fig. 9 as an example), as shown in figure 14, it can be by the image in large-size screen monitors interface 802 by original full screen pictures size reduction 85%, and the center at Image Adjusting to large-size screen monitors interface after reducing 85% is obtained into the target equal with picture size is initially shown and shows picture, at this time, target is shown in the target area for being located at center 85% in picture as the active area with essence display content.
So, after target is shown that picture is sent to external display device by terminal, still as shown in figure 14, external display device shows that picture carries out overscan to the target received, i.e. interception target shows that the picture at picture center 95% is shown.Since the picture intercepted when overscan is greater than above-mentioned active area, external display device can still show complete large-size screen monitors interface 802 in display.
In other embodiments of the application, as shown in figure 15, external display device can also be shown each candidate screen size in set interface 1001 by way of progress bar 1401, user can change the progress of progress bar by the sliding block 1402 of dragging progress bar 1401, thus target picture size when corresponding candidate screen size being selected to show equipment display as subsequent external.
Still shown in Figure 15, user is when dragging sliding block 1402, external display device can show the picture preview effect 1403 of candidate's screen size at slide position in set interface 1001, so that user meets according to picture preview effect selection the screen size of itself use habit.
S704, it is operated in response to user in the input of above-mentioned set interface, terminal obtains the target picture size of user's selection.
The target that above-mentioned target picture size may be used to indicate terminal generation shows the size in picture with the target area of essence display content.For example, above-mentioned target picture size is specifically as follows the target proportion between target area and target display picture, for example, 95%, i.e. terminal shows have 95% picture for the picture with essence display content in picture to the target of the subsequent transmission of external display device；In another example above-mentioned target picture size can show the size of target area in picture directly for target, for example, the target area of 1900 × 1000 resolution sizes.
After user chooses a certain candidate screen size in multiple candidate screen sizes that above-mentioned set interface 1001 provides, the candidate screen size that external display device can choose user is sent to terminal as target picture size, which draws Face size may include that subsequent external shows that the display picture in equipment accounts for the target proportion of external display device screen.Certainly, which can also include the length and high ratio of subsequent display screen, such as 16:9 etc..So that SS later is when transmitting display picture in real time to external display device, display picture can be zoomed in and out according to the target picture size, to provide the signal source of complete display picture for external display device.
Specifically, terminal can be found in following step S705-S707 for the method that the signal source that external display device provides complete display picture is shown, wherein step S705 and step S705 ' is two kinds of optional implementations.
External display device initial display picture to be shown is converted to the target being adapted with above-mentioned target picture size and shows picture by S705, terminal, initial to show that picture and target show that picture all has the display screen size determined in step 702.
After terminal gets the target picture size that external display device is arranged in user, it can be stored into the memory of terminal.It is subsequent, when user, which triggers external display device, to be shown, such as, when user opens a certain application shown in external display device, the incoming event that user triggers can be sent to terminal by external display device, it is the picture to be shown that external display device generates that size is above-mentioned display screen size, such as initial display picture by terminal.
At this time, by taking above-mentioned target picture is having a size of screen 80% is accounted for as an example, as shown in Figure 16 A, terminal is that the initial display picture 1501 that external display device generates is size with the external display device matched 10*10 of rate respectively, according to 80% target picture size, the initial display picture 1501 of generation first can be reduced 80% by terminal, obtain the image zooming 1502 of 8*8.In turn, on the basis of the target position where initially showing picture 1501, the image zooming 1502 of 8*8 is adjusted to the center of target position.As shown in figure 16, the image zooming 1502 of 8*8 can be moved 10*10%=1 along the positive direction of X-axis by terminal, move 10*10%=1 along the positive direction that Y-axis moves, so that image zooming 1502 is moved to the center of original initial display picture place target position.At this point, the surrounding of image zooming 1502 can be filled black or other colors by terminal, obtains target identical with 1501 size of picture is initially shown and show picture 1503.It can be seen that, target shows that picture 1503 is identical as the initial display size of picture 1501, but target shows that the area of active area in picture 1503 accounts for entire target shows picture 1503 80%, i.e. target shows the target area in picture 1503 equipped with 80% for being laid out display content.
Wherein, as shown in figure 17, above-mentioned initial display picture 1501 can be entire display interface to be shown in external display device, the one or more windows (window) being also possible in entire display interface, it can also be some specific icon in window, the embodiment of the present application does not do any restrictions to this.
Illustratively, by taking Android operation system as an example, Android operation system can be divided into four layers, be application layer (i.e. APP layers), application framework layer (i.e. Framework layers), system Runtime Library layer (i.e. Libraries layers) and Linux inner core respectively from high level to low layer.
Wherein, Linux inner core can be used as hardware (such as, CPU, network interface card and memory etc.) and software stack between level of abstraction, it can hide particular hardware details to provide unified service for upper layer (system Runtime Library layer, application framework layer and application layer).It include some libraries C/C++ in system Runtime Library layer, such as, media library, the library system C and display management library (Surface Manager) etc., these libraries can be used by component different in android system, and system Runtime Library layer can provide service by Framework layers for developer.Framework layers provide one for developer can API framework used in access application completely.Specifically, Framework layers provide very more API for development and application program, the APP for meeting related service demand can be constructed by the corresponding API of calling.And application layer mainly includes the APP write with java language, behaviour of the user on operation APP When making interface, by calling the related API in Framework layers, is interacted with system Runtime Library layer or Linux inner core, realize function corresponding with the operation interface.
So, in the embodiment of the present application, as shown in figure 18, include in the system service (system service) of Framework layers of maintenance window manager service (window management service), and the target picture size that maintenance has external display device to send in the PC manager service (PCization management service) dedicated for safeguarding and realizing terminal PC function, the PC manager service.Window state animator (Window state renderer) is provided in window manager service, generally, the Activity of each application corresponds to a window, and window state animator can be used for drawing and managing the window surface and window animation of the window.
In this way, window state animator is when drawing each window (such as initial display picture A) for external display device, the target picture size of user setting can be obtained from PC manager service, and then is drawn the target being adapted with target picture size and shown picture A.
It should be noted that, in the embodiment of the present application, when above-mentioned initial display picture is complete display interface to be shown in external display device, it include one or more windows (or icon) in the usual display interface, so, terminal can convert each window (or icon) according to method described in step S704 when drawing each window (either icon), and the target after finally obtaining conversion shows picture；The display interface can also be converted according to method described in step S704 after entire display interface of completing, the target after can also being converted shows picture, and the embodiment of the present application does not do any restrictions to this.
In addition, the window of one or more target types, size of this kind of window without adjusting display picture, such as the window of wallpaper type can also be stored in advance in terminal.The edge of this kind of preset window usually will not be comprising important information needed for user, therefore, the phenomenon that information needed for the image in this kind of window will not cause user after being over-scanned is lost.So, when terminal judges that the window currently drawn is the window of above-mentioned target type, without executing above-mentioned steps S704, terminal can continue to use existing window method for drafting and draw the window, and the window drawn out is sent to external display device and is shown；When terminal judges that the window currently drawn not is above-mentioned preset window, the window can be converted according to method described in above-mentioned steps S704, the target after finally obtaining conversion shows picture.
S705 ', terminal draw target to be shown having a size of external display device according to above-mentioned target picture and show picture.
In another implementation of the application, when external display device needs to show the display picture of certain display screen size, such as, when the desktop picture of 10*10, terminal can be according to the above-mentioned target picture size of user setting, the initial painting canvas (canvas) that system default when drawing the display picture uses is revised as target painting canvas, wherein can only draw display picture in target painting canvas in target area identical with above-mentioned target picture size.So, subsequent terminal can draw above-mentioned display picture in the target area in the target painting canvas, at this point, obtained target shows that the target formed after picture and conversion in step S704 shows that picture is identical.
Illustratively, by taking above-mentioned target picture is having a size of screen 80% is accounted for as an example, as shown in fig 16b, the initial painting canvas 1601 of 10*10 can be reduced into 8*8 according to the target picture size first before drawing picture to be shown by terminal.In turn, the target painting canvas 1602 of background color formation and 10*10 is filled around the initial painting canvas 1601 after diminution.As can be seen that the size of target painting canvas 1602 is identical as initial painting canvas 1601, but the target area for only having centrally located 8*8 in target painting canvas 1602 can be used for drawing display picture.Therefore, still as shown in fig 16b, terminal can be laid out display content, such as text, image and icon etc. in display picture in the target area of target painting canvas 1602, finally obtain and show picture with target identical in Figure 16 A.
Wherein, it when terminal draws display content in the target area of target painting canvas 1602, can still be drawn according to above-mentioned target Layout is in target area after the element to be shown of default size is reduced 80% by face size, and certainly, terminal can also be directly by the element layout to be shown of default size in above-mentioned target area, and the embodiment of the present application does not do any restrictions to this.
S706, terminal send above-mentioned target to external display device and show picture.
After S707, external display device show that picture over-scans to target, the target in its display after output overscanning shows picture.
In step S705-S706, the target obtained after scaling is shown that picture is sent to external display device by terminal, at this time, as shown in Figure 13 or Figure 14, external display device shows that picture can over-scan to the target received, for example, extracting target shows that the display data for being located at center 95% in picture are shown.So, since the picture area extracted when external display device overscanning is greater than or equal to the area that the target that terminal generates shows active area in picture, therefore, the information that the display picture that equipment receives is shown in terminal PC scene lower outer portion is completely, to can avoid causing to show the incomplete phenomenon of picture because of overscan.
It should be noted that, only display picture is illustrated using 95% withdrawal ratio with external display device when overscan in above-described embodiment, it can be understood that, those skilled in the art can be configured according to specific withdrawal ratio of the practical application scene to overscan, when when scaling (i.e. the target picture size of user setting) of the terminal to initial display picture being less than or equal to external display device overscan to the withdrawal ratio of display picture, external display device can obtain completely showing picture after overscan.
In addition, in the image processing method of terminal provided by the present application, after terminal and external display device establish connection, if external display device is capable of detecting when the display picture recovery rate that current system is arranged in overscan option, which can be sent to terminal by external display device.In turn, above-mentioned target picture can be sized to value corresponding with the display picture recovery rate automatically by terminal.So, when subsequent terminal sends initial display picture to be shown to external display device, it still can be according to method shown in above-mentioned steps S704-S706, initial display picture is zoomed in and out using the target picture size, the target that scaling obtains is shown that picture is sent to after external display device carries out overscan and is shown.Since above-mentioned target picture size is corresponding with the display picture recovery rate, therefore, the display picture that external display device obtain after overscan is just the active area in target display picture, it can be maximized in external display device at this time and completely show that the target shows picture, overcome the problems, such as to show that picture is incomplete caused by because of overscan.
