Specific embodiment
For making the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with specific embodiment,
And referring to the drawings, the present invention is described in more detail.
It should be noted that the statement of all uses " first " and " second " is all in the embodiment of the present invention
In order to distinguish the entity of two same names non-equal or the parameter of non-equal it is seen that " first " " second "
Only for the convenience of statement, should not be construed as the restriction to the embodiment of the present invention, subsequent embodiment is to this no longer
Illustrate one by one.
With reference to Fig. 1, show the schematic flow sheet of the embodiment of the method for video for the dynamic amplification that the present invention provides.
The method that described dynamic amplification shows video, including：
Step 101：Under video broadcasting condition, obtain amplifying gesture touching instruction in real time；Wherein, reference
The arrow of small test tube both sides in accompanying drawing 3, described amplifying gesture touching instruction optionally refers to that starting point is at 2 points
Touch, and the movement locus of two touch points is essentially linear, and the direction of motion of two touch points is base
This contrary touch gestures.
Step 102：According to the generation position of amplifying gesture touching instruction, it is calculated specified magnification region；
Preferably, this step 102 also can further include following process step：
Obtain the coordinate of the rearmost position of two touch points；
Calculate the x-axis distance between the rearmost position of two touch points and y-axis distance, and two touch points
The midpoint of initial position；
Using the midpoint of two touch point initial positions as the center of specified magnification region, using x-axis apart from as
Length on the x-axis direction of specified magnification region, using y-axis distance as the y-axis direction specifying magnification region
On length；
(referring to the drawings the little square frame in 4, it is the specified amplification region of this embodiment to obtain specified magnification region
Domain).Thus the specified amplification region that just can be amplified needed for obtaining according to the generation position of amplifying gesture touching instruction
Domain, and need not still further be selected.So, the triggering of amplification instruction is completed by an instruction and put
The selection in big region.
Step 103：After the completion of video data decoding, can obtain video for display single-frame images,
According to the coordinate value of specified magnification region, extract from original video single-frame images successively and specify magnification region
Single-frame images；
Step 104：Amplified video broadcast window is created in the video playback area beyond specified magnification region
(referring to the drawings the big square frame in 4, it is the amplified video broadcast window creating in this embodiment)；Described
The size of amplified video broadcast window, is optionally less than 1/4 video playback area, specifies more than 2 times and puts
Big region.
Optionally, described step 104 also can further include following process step：
Screen is divided into 4 blocks of shape size identical, respectively upper left block, lower-left block, the right side
Upper block, bottom right block；
Judge the position specifying magnification region to be centrally located at screen；
If specifying magnification region to be centrally located at the upper left block of screen, create in the bottom right block of screen
Amplified video broadcast window；
If specifying magnification region to be centrally located at the lower-left block of screen, create in the upper right block of screen
Amplified video broadcast window；
If specifying magnification region to be centrally located at the upper right block of screen, create in the lower-left block of screen
Amplified video broadcast window；
If specifying magnification region to be centrally located at bottom right block or the screen center of screen, in the upper left of screen
Amplified video broadcast window is created in block.So it is designed to avoid specifying magnification region to broadcast with amplified video
Put window to overlap；If certain amplified video play area is unavoidably overlapped with specified magnification region
When, also can correspondingly adjust position or size of amplified video broadcast window etc..
Step 105：The single-frame images of specified magnification region is carried out image and is amplified to amplified video broadcast window
Size, and show successively in amplified video broadcast window.So can achieve folding in real time of enlarged drawing
Plus play.
From above-described embodiment as can be seen that the dynamic amplification that the present invention the provides method that shows video, by putting
Big gesture receiving amplification instruction and therefrom to obtain specifying after magnification region, then outside specified magnification region
Create amplified video broadcast window in video playback area, and play enlarged drawing successively wherein, thus pin
The interested amplification to video designated area that is partially completed in user is play, with user friendly viewing.
Preferably, described dynamic amplification shows that the method for video also includes step 106：Monitor and real-time response
The operational order of amplified video broadcast window.
Here, while creating amplified video broadcast window, the window of amplified video broadcast window can be added
Mouthful pattern (as shown in Figure 4), the window upper right corner occurs the icon of X button pattern, when listening to pass
Close the click commands of button icon, amplifying display function can be closed in real time；Additionally, work as listening to amplification
The dragging instruction of video playback window, can be with the position of real-time adjustment amplified video broadcast window, when listening to
Dragging to window border, can be with the size of real-time adjustment window.
Further, the described step monitoring the simultaneously operational order of real-time response amplified video broadcast window also may be used
Including following process step：
Listen to new amplifying gesture touching instruction；
Judge whether this amplifying gesture touching instruction occurs in the position of amplified video broadcast window；
If so, then secondary image amplification is carried out to the single-frame images of specified magnification region, and by secondary amplification
The single-frame images of specified magnification region is cut to the size of amplified video broadcast window on the basis of its center, and
Amplified video broadcast window shows successively；
If it is not, then not making any process.
So, when listening to the amplifying gesture touching instruction for amplified video broadcast window, then it is judged as
Need to carry out secondary amplification to the image of display in amplified video broadcast window, respond the instruction of this secondary amplification,
Secondary amplification is carried out to image, meets the viewing demand of user.
Wherein, the multiplication factor of secondary amplification instruction is optionally 2-4 times of former enlarged drawing.
