Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention by receive start video calling solicited message when, obtain specify rotation angle value with
The rotation angle of camera is adjusted, thus according to the use habit or use demand of different user, is set not in video calling
The rotation angle of same camera；In addition, rotation processing is carried out to the image that camera obtains according to specified rotation angle value, from
And it is upright image by reverse image rotation.
Fig. 1 shows the realization flow chart of the method for control camera rotation provided in an embodiment of the present invention, and details are as follows：
In step S101, when receiving the solicited message for starting video calling, start the camera.
Herein, starting the solicited message of video calling includes the request letter generated during mobile terminal one video calling of initiation
The solicited message generated during a video calling is answered in breath or mobile terminal confirmation.When the request for receiving startup video calling
During information, mobile terminal starts camera.Optionally, after mobile terminal starts camera, shown by the screen of mobile terminal
Show the image that camera obtains.
In step s 102, obtain and specify rotation angle value, and the camera is controlled to rotate to the specified anglec of rotation
Angle value.
Herein, specified rotation angle value can be after camera is started, and be generated by user's manual rotation camera
Rotation angle value, or mobile terminal acquiescence rotation angle value, be not limited thereto.It obtains and specifies rotation angle value
Afterwards, camera rotation is controlled according to specified rotation angle value.
It should be noted that specified rotation angle value refers to the angle value of assigned direction and preset direction.Wherein, specify
Direction referred to when camera is rotated to specified rotation angle value, is shot with the vertical lens of camera and being directed toward by lens
The direction of object.Preset direction by user can also be specified, be not limited thereto by system default.For example, preset direction
It refers to vertical with the screen surface of mobile terminal and by outwardly directed direction on the inside of screen.When specified rotation angle value is 0
When spending, assigned direction is parallel with preset direction, at this point, the camera in the present embodiment is equivalent to a front camera；When specified
When rotation angle value is 90 degree, assigned direction is parallel with the long side of mobile terminal and is directed toward top by the bottom of mobile terminal
(wherein, the bottom of mobile terminal refers to bottom when mobile terminal is upright, and the top of mobile terminal refers to moving in direction
Top when terminal is upright, when mobile terminal is upright, the long side of mobile terminal is parallel with vertical direction, and the top of mobile terminal
End is higher than bottom)；When specified rotation angle value is 180 degree, assigned direction is parallel with preset direction, at this point, in the present embodiment
Camera be equivalent to a rear camera.
In step s 103, start video calling, and pass through the postrotational camera and obtain image.
After rotating camera to specified rotation angle value, start video calling, and pass through postrotational camera and obtain
Image.Camera obtains the frame per second of image as preset frame rate, for example, preset frame rate is 20FPS (Frame Per Second, frame
It is per second), it is not limited thereto.Optionally, the picture fluency adjustment camera that mobile terminal is conversed according to current video obtains
The frame per second of image.
In step S104, whether need to carry out at rotation according to the described image that specified rotation angle value judges to obtain
Reason.
Herein, by judge specify rotation angle value whether meet preset condition judge obtain image whether needs
Carry out rotation processing.When specified rotation angle value meets preset condition, judgement need not carry out at rotation the image of acquisition
Reason；When specified rotation angle value is unsatisfactory for preset condition, judge to need to carry out rotation processing to the image of acquisition.Wherein, in advance
If condition can be that rotation angle value is specified to be less than 60 degree, it is not limited thereto.
Preferably, whether the described image that the basis specifies rotation angle value to judge to obtain needs to carry out rotation processing bag
It includes：
Judge to specify whether rotation angle value belongs to predetermined angle section, if so, the described image for judging to obtain need not
Carry out rotation processing；If it is not, the described image for judging to obtain needs to carry out rotation processing.
Here, predetermined angle section can include [0,60) and/or (300,360).When specified rotation angle value is less than 60
When degree or specified rotation angle value are more than 300 degree and are less than 360 degree, the image for judging to obtain need not carry out rotation processing；
When specified rotation angle value is greater than or equal to 60 degree and is less than or equal to 300 degree, the image for judging to obtain is rotated
Processing.Predetermined angle section can also include [0,90) and/or (270,360), be not limited thereto.
In step S105, if it is determined that the described image obtained need not carry out rotation processing, then acquisition is directly displayed
Described image.
When the image for judging to obtain need not carry out rotation processing, acquisition is directly displayed by the screen of mobile terminal
Image, and the image of acquisition is directly sent to another terminal for carrying out video calling.
In step s 106, if it is determined that the described image obtained needs to carry out rotation processing, then by the described image of acquisition
180 degree is rotated, and shows postrotational described image.
When the image of acquisition needs to carry out rotation processing, after the image rotation 180 degree of acquisition, then pass through mobile terminal
The postrotational image of screen display, and by postrotational image be sent to carry out video calling another terminal.
