To zoom area.
Step S103 determines to contract to zoom area according to the first end touch signal and the second end touch signal
Target area of putting that treated.
Step S104 is played out target area is plotted to the video image in zoom area.
When user needs to zoom in or out video being played on, selection is touched by finger and needs area to be scaled
Then domain is determined that the video image to the region is amplification or reduces by sliding finger, stopped after two finger slidings
Position between region be scaling processing after target area.By amplification for, user when watching video being played on,
When needing to amplify some region, as shown in Figure 2 a, user is selected by finger to zoom area, wherein two differences
"×" shape respectively indicates the first initial touch signal and the second initial touch signal, and region therebetween is to zoom area.Finger
After selection is to zoom area, (as shown by arrows in figure) is slided to opposite direction, slides into position shown in "○" in Fig. 2 b
(first, which terminates touch signal and second, terminates touch signal) is set, is therebetween target area.In this way, in playing process later
In, the video image originally to play in zoom area is plotted in target area and is played out, is realized to video image
Partial enlargement processing.
It should be noted that in the present embodiment, after the part to video image zooms in or out processing, the portion
The broadcasting of the video image divided does not influence the broadcasting of the other parts content of video, the video content in coverage goal region
It plays, in this way, not generating black background when video image is reduced and played, can also be compared in amplification and check other areas
Domain content, the region and the target area after scaling that user can according to need selection scaling, substantially increases user experience.
Preferably, according to the first initial touch signal and the second initial touch signal determine video source being played on to
Zoom area comprises determining that the first initial touch signal fastens corresponding first coordinate in the resolution coordinates of touch screen, and
Second initial touch signal fastens corresponding second coordinate in the resolution coordinates of touch screen；First coordinate is converted into video source
Coordinate system on third coordinate, and the 4-coordinate the second coordinate being converted on the coordinate system of video source；It is sat with third
Mark and two vertex of the 4-coordinate as the first rectangular area, using the first rectangular area as to zoom area.
It is all the coordinate in the resolution ratio of touch screen since touch signal is corresponding, user is in touch screen in the present embodiment
Upper touch signal is first fastened in the resolution coordinates of touch screen and determines its corresponding coordinate, then by the conversion of coordinate system,
The coordinate (third coordinate and 4-coordinate) converted thereof into video source coordinate system obtains regarding using the coordinate as vertex
The first rectangular area on the coordinate system of frequency source, the region are band zoom area, thereby determine that out and need to amplify in video source
Or the region reduced.
Further, target area will be plotted to the video image in zoom area and played out comprise determining that first
End touch signal fastens corresponding Five Axis in the resolution coordinates of touch screen and the second end touch signal is touching
The resolution coordinates of screen fasten corresponding 6th coordinate；With Five Axis and the 6th coordinate for two vertex, the second square is determined
Shape region；The apex coordinate of first rectangular area is mapped to the apex coordinate of the second rectangular area, in the second rectangular area
Draw the video image of the first rectangular area.
When carrying out the diminution or enhanced processing with zoom area, it is thus necessary to determine that target area on the screen.According to
The touch signal (the first end touch signal and the second end touch signal) of user's finger determines its corresponding coordinate the (the 5th
Coordinate and the 6th coordinate), the second rectangular area i.e. target area is determined in this, as vertex, broadcasting after that is to say scaling processing
Window is put, the apex coordinate of the first rectangular area (on the coordinate system of video source) is then being mapped to the (touching of the second rectangular area
The resolution coordinates for touching screen are fastened), the video image that the first rectangular area is then drawn in the second rectangular area plays out.
Preferably, after receiving the first slip signals and the second slip signals, method further include: believed according to the first sliding
Number and the glide directions of the second slip signals determine that the video image to zoom area is amplification or reduces, wherein first is sliding
The glide direction of dynamic signal and the glide direction of the second slip signals are opposite, it is determined that reduce；The sliding of first slip signals
The glide direction of direction and the second slip signals is opposite, it is determined that for amplification.
In the present embodiment, the amplification of video image is still reduced, can be believed by the first slip signals and the second sliding
Number glide direction determine.As shown in Figure 2 a, the direction of two slip signals is opposite, then is amplification, whereas if thinking
It is right, then it is diminution.
Optionally, it can also be and determined according to the sliding distance of the first slip signals and the second slip signals to zoom area
Video image be amplification or reduce, wherein if the corresponding coordinate of the first initial touch signal and the second initial touch letter
The distance between number corresponding coordinate, which is greater than first, terminates the corresponding coordinate of touch signal and second to terminate touch signal corresponding
The distance between coordinate, it is determined that reduce；If the corresponding coordinate of the first initial touch signal and the second initial touch signal
The distance between corresponding coordinate, which terminates the corresponding coordinate of touch signal and second less than first, terminates the corresponding seat of touch signal
The distance between mark, it is determined that for amplification.
For example, the distance between initial touch signal is L1, terminating the distance between touch signal is L2, if L1 is greater than
L2 is then diminution；It is then amplification that L1, which is less than L2,.Wherein, in carrying out the calculating process such as coordinate conversion, L1 and L2 can also be utilized
Calculate pantograph ratio, i.e. L1/L2, wherein the scaling multiple of image-region is square of the pantograph ratio.
Preferably, method further include: if the glide direction of the first slip signals and the second slip signals be it is in the same direction, really
Surely the operation of zoom area is treated as movement；The movement to zoom area is calculated according to the first slip signals and the second slip signals
Phasor coordinate；The apex coordinate in the region after mobile vector coordinate is moved will be added after the apex coordinate of zoom area, with
Region after determining movement；It draws in region after movement to the video image in zoom area.
In the present embodiment, the region of selection can also be moved, can be and moved after zooming in or out,
And only part is moved without zooming in or out.In moving process, sliding finger is also needed, thus in terminal
In the present embodiment, the movement to zoom area is calculated according to the first slip signals and the second slip signals for upper generation slip signals
Then phasor coordinate adds the mobile vector coordinate by the apex coordinate of moving area respectively, the vertex after movement can be obtained
Coordinate is drawn out video image in the corresponding region of the apex coordinate and is played out.
