Embodiment 1
[0043] Such as figure 1 As shown, the video communication terminal of an embodiment of the present invention includes an audio module, a video module, an adjustment module, and a control module, wherein the control module is connected to the audio module, the video module, and the adjustment module respectively, and the adjustment A module is connected to the video module.
[0044] The audio module is used to collect audio information, convert the collected audio information into audio signals and send them to the control module.
[0045] The video module is used to collect video information, convert the video information into video signals and send them to the control module.
[0046] Video modules are usually cameras.
[0047] The control module is used to determine the adjustment parameters of the video module according to the received audio signal and video signal, and send the adjustment parameters to the adjustment module.
[0048] The adjustment module is used to con...
Embodiment 2
[0075] Such as Figure 5 As shown, a video communication method of an embodiment includes the following steps:
[0076] Step 101, the analysis sub-module in the audio module performs frequency domain analysis on the pre-collected audio signal to obtain the characteristics of the audio signal.
[0077] Step 102, when the video communication terminal is used for communication, the audio module collects the audio information of the user during the call, and converts it into an audio signal.
[0078] Step 103, the filtering sub-module filters the noise signal in the audio signal according to the characteristics of the audio signal, and transmits the noise signal to the control module.
[0079] Step 104, the video module collects video information, converts the video information into a video signal, and transmits it to the control module.
[0080] Step 105, the control module determines the adjustment parameters of the video module according to the received audio signal and video...

Abstract
Disclosed is a video communication terminal, comprising an audio module, a video module, an adjustment module and a control module. The audio module is used to acquire audio information, convert the acquired audio information into an audio signal and then transfer the audio signal to the control module. The video module is used to acquire video information, convert the video information into a video signal and then transfer the video signal to the control module. The control module is used to determine adjustment parameters of the video module according to the received audio signal and video signal, and send the adjustment parameters to the adjustment module. The adjustment module is used to adjust the video module according to the adjustment parameters. The video communication terminal of the present invention automatically tracks the face of a user.
Description
technical field [0001] The invention relates to the communication field, in particular to a video communication terminal and a video communication method. Background technique [0002] With the development of wireless communication technology, wireless communication terminal equipment, commonly known as wireless terminal, has become a necessity in people's life. The basic function of wireless terminals is to provide voice calls. In recent years, 3G technology has gradually matured, and video call technology has gradually been introduced into wireless terminals. Video call methods are becoming more and more popular among users. [0003] Most of the built-in cameras of existing wireless terminals are fixed inside the wireless terminal, or can only be rotated at a small angle. The avatar is out of the viewing range of the camera, so that the other party in the video call cannot see the video avatar of the user. Contents of the invention [0004] The invention provides a vid...
