Embodiment 1

[0073] Taking the mobile phone videophone call as the first example below, its working process is briefly explained from the user's usage mode. Assuming that mobile phones A and B are two terminals for videophone calls, mobile phone A and B, as described in the above-mentioned embodiments, have defined the capability set of controlling and controlled camera movement in the H.245 protocol, and mobile phone A The camera of phone B supports telescopic lens, and the camera of mobile phone B supports front and rear rotation (the camera of some clamshell phones is set on the axis of the clamshell and can rotate back and forth).

[0074] During the call between mobile phone A and mobile phone B, if the user of mobile phone B wants to zoom in the lens to look at the user of mobile phone A, he can send a request to the user of mobile phone A to adjust the zoom lens. After the user of mobile phone A receives the request, if he agrees, the user of mobile phone B Enter the lens zoom adjus...

Embodiment 2

[0078] Taking the fixed-terminal video conference following H.245 as a second example, the process of user use is briefly described. Assume that two users are communicating through video conferencing terminals C and D. The user of video conference terminal C feels that the user of video conference terminal D is not in the center of the screen, and wants to adjust the camera rotation of the other party's video conference terminal D locally to obtain a better picture effect. Then the user of terminal C can initiate a camera rotation request to terminal D through the remote control, and the transmitted signal includes the rotation direction and rotation angle. After receiving the camera rotation request, terminal D parses out the request, and then automatically controls the hardware drive device to rotate the camera. Make the terminal C user obtain the required video conference picture.

Abstract

The invention discloses a lens control method and terminals. The method comprises the following steps: a second terminal receives control information of a first terminal in video communication connection with the second terminal; and the second terminal controls the motion of a lens mechanical device of the second terminal according to the control information. According to the method and the terminals, the problem that the camera mechanical rotation or telescopic device of the opposite party cannot be controlled from the far end in video communication is solved, and the user experience effect is further improved.

Description

technical field [0001] The present invention mainly relates to the communication field, and in particular, relates to a lens control method and a terminal. Background technique [0002] Entering the 3G era, the video communication function of mobile phones has been greatly developed. Under the 3G network, not only can mobile phone users make video calls, share videos during voice calls, and obtain videos from servers, but mobile phone users can even communicate with computer users via video. [0003] In the field of mobile video communication, the most commonly used communication protocol is the H.324 protocol set. It includes H.223 multiplexing protocol, H.245 system control protocol, H.263 video coding protocol, G.723.1 audio coding protocol, etc. [0004] figure 1 It is the process of establishing a called video call based on the H.324 protocol in related technologies, as shown in the attached figure 1 As shown, taking the called terminal process as an example, the vi...
