Video data and transmission video data, wherein video data includes voice data and image data.
Step S302 judges whether mobile terminal user leaves mobile terminal by the monitoring of the user to mobile terminal,
It is to execute corresponding video secrecy operation.
In the present embodiment, after mobile terminal establishes video calling event, pass through the prison to mobile terminal user
It surveys to judge whether mobile terminal user has left mobile terminal, if so, corresponding video secrecy operation is executed, specifically,
Video secrecy operation includes, and when determining that mobile terminal user leaves the mobile terminal, stops playing the video data obtained, i.e.,
When mobile terminal user carries out video calling not by mobile terminal, it is whole that other movements in video calling event are had received from the background
The video data at end, however the received video data is not played out into (including screen is shown, audio output).
When judging whether mobile terminal user leaves mobile terminal, specifically, it can determine whether mobile terminal user deposits
In screen operation of going out, screen operation of going out if it exists then determines that mobile terminal user leaves the mobile terminal, to fast and accurately judge
Whether mobile terminal user is because leaving mobile terminal due to missed portion video calling content out.
Preferably, after the video data for stopping playing acquisition, the video data of acquisition is recorded, consequently facilitating
Mobile terminal user carries out the partial video dialog context missed when coming back to and carrying out video calling by mobile terminal
Solution.
It is further preferred that the video counts after playing will be stopped when determining that mobile terminal user leaves the mobile terminal
Voice data in is converted into offline text, after determining that mobile terminal user leaves the mobile terminal, and determines again
When mobile terminal user does not leave the mobile terminal, the offline text being converted to is subjected to display output, thus not interfering
While mobile terminal user's video calling, the integrity degree of mobile terminal user's video calling is improved.
The video call method for present embodiments providing a kind of mobile terminal, for mobile terminal.The present invention, which works as, to be monitored
When mobile terminal establishes video calling event, obtains the video data of video calling event at least two parties and carries out output operation,

When judging whether mobile terminal user leaves mobile terminal, it is preferable that with prefixed time interval, periodically from
Single-frame images is intercepted in video data, judges whether mobile terminal user leaves movement end further according to the single-frame images of interception
End, judges mobile terminal user whether because leaving mobile terminal, to improve to shifting by the single-frame images in video data
The accuracy of dynamic terminal user's judging result.In the embodiment of the present invention when it is implemented, prefixed time interval is set as 1-3s, more
To suit mobile terminal user's use habit, to improve practicability of the invention.Optionally, when being intercepted from video data
Single-frame images when face is not present, determine that mobile terminal user leaves the mobile terminal, it is on the contrary then determine mobile terminal user
The mobile terminal is not left, so that the deterministic process for whether leaving the mobile terminal to mobile terminal user simplified.
It is further preferred that first obtaining as shown in figure 5, Fig. 5 is the preferred flow schematic diagram for judging mobile terminal user position
The facial image in the single-frame images of interception is taken, then the facial image in the single-frame images is matched with default face database,
Determine that mobile terminal user does not leave this when it includes at least one facial image in the single-frame images in face database that this, which is preset,
Mobile terminal, it is on the contrary then determine that mobile terminal user leaves the mobile terminal, judge that mobile terminal is used to further improve
The accuracy of family position.
Wherein, the face set for presetting the video calling affiliated person that face database is the mobile terminal side, presets face database
Foundation is when the video calling event of the mobile terminal starts, it is preferable that in the view for obtaining video calling event at least two parties
Frequency according to and after carrying out output operation, at least one face in front of the camera of the mobile terminal is obtained by video data
Image, and at least one facial image is stored to default face database, consequently facilitating the position of subsequent judgement mobile terminal user
It sets.
The video call method for present embodiments providing a kind of mobile terminal, for mobile terminal.The present invention, which works as, to be monitored
When mobile terminal establishes video calling event, obtains the video data of video calling event at least two parties and carries out output operation,
Wherein, output operation includes playing video data and sends video data, judges to move by the monitoring of the user to mobile terminal
Whether dynamic terminal user leaves mobile terminal, is, executes corresponding video secrecy operation.The present invention enters view in mobile terminal
After frequency is conversed, the position between mobile terminal user and mobile terminal is judged according to the monitoring to mobile terminal user, thus
The leakage that video data is effectively prevented by video secrecy operation, improves the confidentiality of video data.
