Step S303: and extracting the biological characteristic information of the human face from the image information.
In step S303, the biometric information of the human face may include face shape information, size information, pupil information, facial feature information, and other information with identification, where the facial feature information may include facial features such as double eyelids, bang, moles, and the like.
It can be understood by those skilled in the art that if only a user exists around the mobile terminal, only the biometric information of the face of the user is extracted from the image information, and if a third person other than the user exists around the mobile terminal, the biometric information of the face of the user and the face of the third person other than the user are simultaneously extracted from the image information.
Step S304: and judging whether the extracted biological feature information of the human face is matched with the preset biological feature information, if not, executing the step S305, otherwise, executing the step S309.
In step S304, preset biometric information is obtained as follows: the method comprises the steps of obtaining image information of a face of a user, extracting biological feature information of the face of the user from the image information of the face of the user, and storing the biological feature information in a mobile terminal to form preset biological feature information.
In this embodiment, the preset biometric information may include facial features of the user different from those of the ordinary person, such as: the double-edged eyelid, the bang, the nevus and the like, so that whether the extracted biological characteristic information of the face is the face of the user can be judged more quickly.
In this embodiment, it is determined whether the extracted biometric information of the face matches the preset biometric information, which is substantially determined whether a third person other than the user is within the viewing range of the front camera. That is to say, when the extracted biological feature information of the face is not matched with the preset biological feature information, it is determined that a third person other than the user joins the periphery of the mobile terminal; and when the extracted biological characteristic information of the face is matched with the preset biological characteristic information, determining that only the user is around the mobile terminal.

Step S305: and judging whether the extracted biological feature information of the human face contains pupil information, if so, executing step S306, and otherwise, executing step S309.
In step S305, when it is determined in step S304 that the biometric information of the extracted face does not match the preset biometric information, it is determined that a third person other than the user is present around the mobile terminal, and at this time, it is further determined whether the biometric information of the extracted face includes pupil information.
In this embodiment, it is determined whether the extracted biometric information of the face has pupil information, which is substantially determined whether eyes of a third person other than the user gazes at a video window of the mobile terminal. That is, when the extracted biological feature information of the face includes pupil information, it is determined that eyes of a third person other than the user watch on a video window of the mobile terminal; and when the extracted biological characteristic information of the face does not contain pupil information, determining that eyes of a third person except the user watch on other places except the video window.
Step S306: the duration of a video window looking at the mobile terminal is obtained.
In step S306, when it is determined in step S305 that there is pupil information in the extracted biometric information of the face, the duration of the video window that is looking at the mobile terminal is further acquired.
The step of acquiring the duration of a video window gazing at the mobile terminal comprises: capturing frame images around the mobile terminal through a front camera at the frequency of n (n is less than or equal to 4) seconds; the frequency of capturing images by the front camera is set to be less than or equal to 4 seconds, and is based on that the frequency of normal human blinks is 5 seconds/time, and the error of the blinking can be reduced by capturing images at the frequency of 4 seconds or lower; analyzing the frame images, and if judging that the pupil information of a third person except the user does not exist in a certain frame image, confirming that the third person except the user does not concentrate on the video window of the mobile terminal; and finally, acquiring the frame number of the frame image without the pupil information of a third person except the user, and obtaining the duration time of the video window watching the mobile terminal according to the frame number.
Step S307: and judging whether the duration time exceeds the preset attention time, if so, executing the step S308, otherwise, executing the step S309.
In step S307, the preset focusing time may be set according to actual conditions, and may be, for example, 3 seconds, 5 seconds, or the like. In this embodiment, when the duration exceeds the preset attention time, it is determined that a third person other than the user is focused on the video window of the mobile terminal; when the duration does not exceed the preset focus time, it is determined that a third person other than the user has only accidentally seen the video window of the mobile terminal.
Step S308: the video window is automatically reduced to alert the user.
In step S208, when it is determined in step S207 that the duration exceeds the predetermined attention time, it indicates that a third person other than the user is paying attention to the video call content of the user, and at this time, the video window is automatically narrowed down to remind the user that the third person other than the user is watching the video call content secretly and to prevent the third person other than the user from continuing watching the video call content.
The operation of automatically reducing the video window specifically includes: and automatically reducing the video window according to a preset size and displaying the reduced video window at a preset position, wherein the preset size can be 1/2, 1/4 and the like of the original video window, and the preset position can be an edge position of the mobile terminal and the like.
Preferably, when it is determined in step S207 that the duration exceeds the predetermined attention time, an operation of saving image information of the periphery of the mobile terminal in an album of the mobile terminal may also be performed to facilitate a subsequent user to know who a third person other than the user is.
Step S309: the video window is kept unchanged.
In step S309, when it is determined in step S304 that the biometric information of the extracted human face matches the preset biometric information, or when it is determined in step S305 that there is no pupil information in the biometric information of the extracted human face, or when it is determined in step S307 that the duration of the video window of the mobile terminal watched by a third person other than the user does not exceed the preset attention time, it is determined that only the user is watching the video window of the mobile terminal around the mobile terminal, and the video window is kept unchanged.
The method and the device have the advantages that when a user carries out video call through the mobile terminal, the image information around the mobile terminal is acquired at preset time intervals; judging whether a third person except the user joins the periphery of the mobile terminal or not according to the image information; if a third person outside the user joins the mobile terminal, further judging whether the third person outside the user is concentrated in the video window of the mobile terminal; and if a third person except the user is concentrated in the video window of the mobile terminal, automatically reducing the video window to remind the user. By the method, the accuracy of automatically reducing the video window can be improved, the safety of video call of a user is improved, and the experience degree of the user on the video call function of the mobile terminal is guaranteed.
