Based on above-mentioned mobile terminal hardware configuration and communication system, each embodiment of the method for the present invention is proposed.
Embodiment one
First embodiment of the invention proposes a kind of method for adjusting resolution ratio.The side of adjustment resolution ratio described in the present embodiment Method can execute on mobile terminal backstage.As shown in figure 3, for according to the method stream of the adjustment resolution ratio of first embodiment of the invention Cheng Tu.
Step S310 obtains the current resolution and original resolution of the figure layer that system foreground is shown.
The current resolution of figure layer refers to resolution ratio when the corresponding image of figure layer is shown in the terminal.The image can To be picture or video image.
The original resolution of figure layer refers to the resolution ratio of the script of the corresponding image of figure layer.
The current resolution of figure layer is limited by mobile terminal hardware.Such as: the resolution ratio of mobile terminal display is 1920 × 1080, the GPU (Graphics Processing Unit, graphics processor) of mobile terminal is maximum to support 2K (2048 × 1080) or 4K (4096 × 2160) resolution ratio, even if the original resolution of figure layer is 2K resolution ratio, user also be can only see The image effect of 1920 × 1080 resolution ratio.
In the present embodiment, before executing pre-set image operation, the current resolution for the figure layer that system foreground is shown is obtained Rate and original resolution.Pre-set image operation can be screen shot operation or screen recording operation.
Specifically, in region to be intercepted, obtaining the current resolution and original of figure layer before executing screen shot operation Beginning resolution ratio;Alternatively, during executing screen recording, every preset time period obtains the current resolution and original of figure layer Beginning resolution ratio.It is possible to further carry out pixel sampling to figure layer, the current resolution of figure layer is determined.Available figure layer Raw image data determines the original resolution of figure layer according to the raw image data.Raw image data includes: figure layer script Resolution data and data volume data.Raw image data can be obtained from the data source that image stores.
Such as: user is after clicking screenshot capture button, the size of operation intercept frame, keeps interception frame region (to be intercepted Region) the part figure layer for needing to intercept is covered, pixel sampling is carried out to the part figure layer, determines the current resolution of the part figure layer The current resolution of rate, part figure layer is also the current resolution of figure layer;Obtain the original graph of figure layer belonging to the part figure layer As data, the original resolution of the figure layer is obtained.
For another example: user is after clicking screen recording button, every preset time period, screenshot is carried out to figure layer, to screenshot Carry out pixel sampling, the current resolution of the figure layer of acquisition;Raw image data belonging to figure layer is obtained, the original of figure layer is obtained Resolution ratio.
In the present embodiment, the quantity of figure layer is one or more, if layer count be it is multiple, it is available every The current resolution and original resolution of a figure layer, or obtain each figure layer current resolution and target figure layer it is original Resolution ratio.
Step S320, judges whether the current resolution of figure layer is less than the original resolution of the figure layer;If it is, executing Step S330;If not, thening follow the steps S310.
If the current resolution of figure layer is less than original resolution, illustrating the resolution ratio of figure layer, there are also widened skies Between, it can increase the video of recording or the clarity of truncated picture by way of expanding figure layer resolution ratio.
The current resolution of the figure layer is expanded preset value by step S330, and to the figure after expansion resolution ratio Layer executes pre-set image operation.
Resolution ratio after figure layer expands is less than or equal to the original resolution of the figure layer and is less than or equal to the maximum that GPU is supported Resolution ratio.
If layer count be it is multiple, preset value expanded to the current resolution of each figure layer, and to expanding resolution ratio The image that multiple figure layers later are formed/synthesized executes pre-set image operation.
Preset value can be preset numerical value, be also possible to the numerical value that user is arranged according to demand, can also be according to pre- If rule selection numerical value.Such as: system foreground shows multiple figure layers, obtain each figure layer current resolution and original point Resolution;It determines the corresponding figure layer of maximum original resolution, calculates the original resolution of the figure layer and the ratio of current resolution, Using the ratio as preset value.
After the current resolution of figure layer is expanded preset value, screenshot capture is executed to the figure layer after expansion resolution ratio Operation or screen recording operation.
During executing screen recording, if resolution ratio switching has occurred in the system foreground of detecting, resolution is generated The corresponding video file in rate switching front and back.Further, if recorded multiple video files, by the multiple video File is spliced into a video file.
Such as: during system background recorded video, video is 480 × 270 in the resolution ratio that foreground is initially displayed, Switching resolution ratio is 1920 × 1080 later, then video when foreground resolution ratio is 480 × 270 in background record independently forms The resolution ratio of one video file, the video file can be greater than 480 × 270;Rear when foreground resolution ratio is 1920 × 1080 The video that platform is recorded independently forms a video file, and the resolution ratio of the video file can be greater than 1920 × 1080;The two Video file can be checked individually, can also be spliced into a complete video file and be checked.
It in the present embodiment, can be in system background dynamic adjustment figure layer if the resolution ratio of system foreground figure layer is smaller Resolution ratio, using biggish resolution ratio to figure layer execute pre-set image operate, in the process, user sees on system foreground Picture (figure layer of display) resolution ratio there is no variation, and execute pre-set image operation after obtain image or view The resolution ratio of frequency is extended, and for user in the image or video for checking acquisition, image sharpness is higher.
Such as: the resolution ratio that mobile terminal is shown is 1920 × 1080;The original resolution of video is 2048 × 1080, Video window is switched to after suspended window, and resolution ratio is reduced into 480 × 270, and the resolution ratio of figure layer where webpage is 1920 × 1080, the current resolution 480 × 270 of figure layer is less than original resolution 2048 × 1080 where video.Executing screen recording When operation, if be not adjusted to the resolution ratio of figure layer where figure layer where video and webpage, video and webpage are closed Resolution ratio at the every frame image obtained later is 1920 × 1080, certainly will will affect the clarity of video.In this way, being based on this reality Example is applied to be adjusted the resolution ratio of figure layer where figure layer where video and webpage, if figure layer selection 1920 where video × 1080 (expand 4 times), then figure layer where webpage is 7680 × 4320 (expanding 4 times), the image being finally synthesizing will be 7680 × 4320 (expanding 4 times);If figure layer where video chooses 2048 × 1080 (expand 16 times), figure layer where webpage is 8190 × 4320 (expanding 16 times), the image synthesized after last will be 8190 × 4320 (expanding 16 times).
Embodiment two
In application scenes, mobile terminal currently shows perhaps multiple figure layers, shows below for multi-layer image Situation is illustrated.
As shown in figure 4, for according to the method flow diagram of the adjustment resolution ratio of second embodiment of the invention.
Step S410 obtains the current resolution of each figure layer and multiple if system foreground shows multiple figure layers The original resolution of target figure layer in figure layer.
Target figure layer is the figure layer or the figure layer where focus of top layer in multiple figure layers.Wherein, the figure where focus Layer refers to the figure layer of user's last operation.
Such as: user checks that webpage, video window are shown on webpage in the form of suspended window while watching video Layer;System foreground shows two figure layers in this way, and figure layer where video is the image of top layer, then the figure layer where video is mesh It marks on a map layer, the current resolution and original resolution of figure layer where obtaining video, the current resolution of figure layer where obtaining webpage.
Step S420, judges whether the current resolution of target figure layer is less than original resolution;If so, thening follow the steps S430;If not, thening follow the steps S410.
Step S430, if the current resolution of target figure layer is less than original resolution, according to the target figure layer Raw image data determines the corresponding preset value of data volume range locating for the data volume of the target figure layer.
Preset multiple data volume ranges and preset value corresponding with each data volume range.
Step S440 expands the current resolution of the target figure layer according to the raw image data of the target figure layer The big preset value.
The raw image data for obtaining target figure layer, reads part image data from the raw image data, makes the figure As the resolution ratio of data is the preset value of the current resolution of target image;Or part point is read from the raw image data The resolution data is filled into target figure layer by resolution data, and the current resolution of target figure layer is made to be extended preset value.
Step S450 expands the current resolution of other figure layers described pre- according to the raw image data of other figure layers If value, alternatively, other figure layers are stretched the preset value.
Step S460 executes pre-set image operation to multiple figure layers after expansion resolution ratio.
Pre-set image operation is that screen shot operation or screen recording operate.
Each figure layer view has an independent figure layer parsing face surface on interface of mobile terminal.According to the upper of figure layer All surface are sent to fliner and are uniformly depicted as a frame image, then export into video flowing by lower grade Z-order.Often It is secondary target figure layer to be sampled when having View switching, if transition occurs for the current resolution of target figure layer, it is necessary to according to The current resolution of target figure layer and the relationship of original resolution judge whether the resolution ratio for readjusting each figure layer.Figure layer Switching independently carry out, general figure layer switches with change resolution, and so every switching of figure layer is primary, just saves primary view Frequency file, such as: system detection to figure layer is cut through 4 times, then can finally generate 4 video files, 4 video files can be with It is provided independently to user, 4 video files can also be stitched together and be supplied to user.
Such as: system foreground plays three videos simultaneously, and three video windows partly overlap two-by-two, figure where the first video The resolution ratio of layer is 480 × 270, and the resolution ratio of figure layer is 320 × 100 where the second video, point of figure layer where third video Resolution is 720 × 720, and the true resolution ratio (original resolution) of these three videos is all 2048 × 1080.Mobile terminal is aobvious The resolution ratio for showing device hardware is 1920 × 1080, if normal record screen, the resolution ratio of video file are 1920 × 1080.When When focus is switched to the second video, in order to guarantee in the video file recorded, the clarity of the second video is higher, can be by second Video is adjusted the resolution ratio of the first video, the second video and the corresponding figure layer of third video as standard.It obtains The raw image data of second video obtains the data volume of the second video, and determines number locating for the data volume of the second video According to the corresponding preset value of amount range, such as: the preset value is 2, then reading part figure from the raw image data of the second video As data, the resolution ratio of the part image data is 2 times of the second video current resolution, to the first video and third video Image stretches 1 times respectively, so that the resolution ratio of the first video and third video also expands as 2 times of current resolution.It crosses herein Cheng Zhong does not change in the display scale and resolution ratio of three videos that foreground plays simultaneously, in the video that recording finishes In file, no change has taken place for the display scale of the first video, the second video and third video, but resolution ratio all expands 2 Times.
In the present embodiment, the information content for determining the target figure layer in multiple figure layers, according to containing much information for target figure layer It is small, the resolution ratio of target figure layer and other figure layers is adaptively adjusted.Further, since the focus of user is generally in mesh It marks on a map layer (figure layer or the figure layer where focus of top layer), so the mainly resolution of adjustment target figure layer in the present embodiment Rate, for the target figure layer to contain much information, information change details is more, the resolution ratio of expansion target figure layer that can be more, for The small target figure layer of information content, information change details is few, can the lesser resolution ratio for expanding target figure layer.
