S304, the view data of described back camera picked-up terminal A;
In the specific implementation, the step that terminal A carries out above-mentioned S301 and S303 can be simultaneously, and step that also can S303 was carried out before the step of S301 is carried out.
S305, terminal A show the two-way view data that described front camera and rear camera absorbs respectively;
Camera was main camera before S306, terminal A were provided with, and back camera is auxilliary camera;
The view data of camera and back camera shooting was provided with 2/3,1/3 scaling before S307, terminal A were respectively;
S308, terminal A are reduced into the picture size of the view data of preceding camera and back camera picked-up original 2/3 and 1/3 respectively;
S309, the described two-way view data after terminal A convergent-divergent is handled synthesizes one tunnel view data;
S310, terminal A is the view data of form H.263 with synthetic coded image data;
S311, terminal A with the image data transmission of described H.263 form to terminal B;
S312, the view data of the described H.263 form of terminal B decoding obtains described synthetic view data;
S313, terminal B show the described synthetic view data that decodes.
Description by the various embodiments described above, the embodiment of the invention is obtained the view data of local terminal by at least two cameras, the multiway images data of obtaining are synthesized processing, transfer to the terminal of video calling after view data after synthetic encoded, realize the disposable transmission simultaneously of multiway images, promoted user experience; In addition, the disposable view data that each camera is obtained of the present invention is transmitted simultaneously, has avoided existing manual switchover camera to select the troublesome operation of image transmitted data, has further promoted user experience.
