Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The method of the adjustment video pictures of the embodiment of the present invention, can adjust the angle of video typing or broadcasting, convenient for users to use, adds practicality and intellectuality.
As shown in Figure 1, the method for the adjustment video pictures of the embodiment of the present invention, is applied to terminal, comprises:
Step 11, obtain the operation instruction information to a screen that described terminal gathers, described screen is the touch-screen of described terminal;
Step 12, determines the anglec of rotation of the video pictures that described screen shows being carried out to rotation process according to described operation instruction information;
Step 13, rotates the video pictures that described screen shows according to the described anglec of rotation.
The method of the adjustment video pictures of the embodiment of the present invention, first obtain the operation instruction information to a screen that terminal gathers, this screen is the touch-screen of this terminal; Then the anglec of rotation of the video pictures that screen shows being carried out to rotation process is determined according to this operation instruction information; Finally the video pictures that screen shows is rotated according to the anglec of rotation.Achieve and utilize contact action to adjust video typing or play the object of angle, convenient for users to use, improve user's impression, add practicality and intellectuality.
In specific embodiments of the invention, described operation instruction information can be a camber line sliding trace on the screen;
The step of above-mentioned steps 12 can comprise:
Step 121, determines the starting point and ending point of described camber line sliding trace according to described operation instruction information;
Step 122, is defined as the described anglec of rotation by the radian between described starting point and described terminating point.
Now, can by pointing the angle that the length of drawing camber line on screen decides to rotate, user can set according to demand, convenient for users to use.
Wherein, the direction described starting point can being pointed to described terminating point is defined as the sense of rotation that the video pictures that screen shows carries out rotation process.
Now, can determine sense of rotation by the direction of finger drawn camber line on screen, user can set according to demand, convenient for users to use.
A kind of specific embodiment, radian between the starting point of user's drawn camber line on screen and terminating point is 90 degree, the direction that starting point points to terminating point is clockwise (or counterclockwise), then determine that the anglec of rotation of the video pictures that screen shows being carried out to rotation process is 90 degree, sense of rotation is clockwise (or counterclockwise).
Further, can also comprise after above-mentioned steps 13:
Step 14, adjusts postrotational video pictures, makes the video pictures after adjustment and described screen adaptation.
Now, the video pictures after adjustment and screen adaptation, as size, resolution etc., make the video pictures after adjustment be more suitable for viewing and admiring, and improves user's impression.
Wherein, the video resolution of screen is seldom foursquare, if the video before rotating is played in full screen, postrotational video length and width exchange, and just can not carry out played in full screen again, therefore, the step of above-mentioned steps 14 can comprise:
Step 141, if postrotational video pictures comprises the part exceeding described screen border, then narrows down to the size that described screen can all show by described postrotational video pictures.
Now, postrotational video pictures all can show in screen, ensure that the normal viewing of user, improves user's impression.
