(in this embodiment, mobile terminal 2 is simultaneously used as a first type mobile terminal and a second type mobile terminal.)
The camera of each handset 2, 3, 4, 5 then takes a video shot and sends the shot real-time video to the handset. The method comprises the steps of carrying out portrait recognition from a real-time image intermittently by each camera on each mobile phone, judging whether a preset face exists or not, taking the camera with the preset face in the image as a working camera, and sending real-time video shot by the working camera to the mobile phone. The preset human face is identified according to the personal facial features prerecorded by the video blogger, only the self-photographing camera 22 on the front side of the mobile phone 2, the main camera 31 on the back side of the mobile phone 3, the main camera 41 on the back side of the mobile phone 4 and the main camera 51 on the back side of the mobile phone 5 photograph the human face of the user 1, and the real-time video photographed by the main camera 31 on the back side of the mobile phone 3, the main camera 41 on the back side of the mobile phone 4 and the main camera 51 on the back side of the mobile phone 5 is transmitted to the mobile phone 2 if the human face of the user 1 is not photographed by the self-photographing camera and the cameras.
Then, the screen of the mobile phone 2 is divided into four areas according to the upper left, the upper right, the lower left and the lower right, and real-time videos shot by the self-shooting camera 22 on the front side of the mobile phone 2, the main camera 31 on the back side of the mobile phone 3, the main camera 41 on the back side of the mobile phone 4 and the main camera 51 on the back side of the mobile phone 5 are respectively displayed.
Finally, the mobile phone 2 tracks the eye movement trajectory of the user 1, and when the duration of the eye movement trajectory of the user 1 staying in one area of the mobile phone exceeds a preset threshold, in this embodiment, the preset threshold is 2 seconds, the frame of the area is highlighted, and the real-time video played in the area is used as an alternative sub-video, for example: when the user 1 stares at the video in the lower left area of the screen of the mobile phone 2, the mobile phone 2 recognizes that the eye movement track of the user 1 stays in the lower left area for more than 2 seconds, copies the real-time video shot by the main camera 41 on the back of the mobile phone 4 as an alternative sub-video, and finally edits the alternative sub-video into a video stream according to the time sequence order and sends the video stream to an output end or a server. The output terminal can be connected to a computer, and the computer is connected to the server. Or directly transmitted to the server so that the server sends the video stream to other users. From this moment on, the content of the video stream is provided entirely by real-time video captured by the main camera 41 of the handset 4. After 1 minute, when user 1 needs to change the camera, for example: when the user 1 stares at the video in the lower right area to watch, the mobile phone 2 copies the real-time video shot by the main camera 51 at the back of the mobile phone 5 as the alternative sub-video by recognizing that the duration of the eye movement track of the user 1 staying in the lower right area exceeds 2 seconds, and the content of the video stream is completely provided by the real-time video shot by the main camera 51 of the mobile phone 5, so that when the user is inconvenient to operate by hand or has a certain distance with the mobile phone, remote control is performed, and different cameras are replaced to shoot new alternative sub-videos to adjust the position of the video stream.
