Fig. 3 is a schematic flowchart of a specific implementation of a mobile terminal screen control method according to an embodiment of the present invention, where an execution body of the method is a mobile terminal in the embodiment of the present invention. Referring to fig. 3, the method for controlling a screen of a mobile terminal provided in this embodiment may include the following steps:
step S301, when the mobile terminal enters a sound amplifying communication state, detecting whether the mobile terminal has a screen display requirement; if there is a screen display requirement, the process proceeds to step S302; otherwise, if there is no screen display requirement, the process proceeds to step S303.
Step S302, the mobile terminal screen is kept in a bright screen state.
And step S303, controlling the mobile terminal screen to be turned off.
When the mobile terminal detects a sound amplifying function starting instruction input by a user in a communication state, the mobile terminal is triggered to start the distance sensor, and whether screen display requirements exist is judged according to data measured by the distance sensor. Specifically, the detecting whether the mobile terminal has a screen display requirement includes:
starting a distance sensor arranged on the mobile terminal, and detecting whether a shielding object exists in front of the mobile terminal through the distance sensor;
if a shielding object is arranged in front of the mobile terminal, measuring the distance between the mobile terminal and the shielding object through the distance sensor, and judging whether the distance is smaller than a preset threshold value or not;
if the distance is smaller than a preset threshold, the mobile terminal has no screen display requirement;
if no shielding object is detected or the distance is greater than or equal to a preset threshold value, the mobile terminal has a screen display requirement.
In this embodiment, if a shielding object is provided in front of the mobile terminal and the distance between the shielding object and the mobile terminal screen is smaller than a preset threshold, it is indicated that the user head is very close to the mobile terminal screen or the mobile terminal screen is placed downward on the shielding object, which indicates that the user does not need to view screen information, so the mobile terminal has no screen display requirement, and at the moment, the mobile terminal screen is controlled to be turned off, so that the energy consumption of the mobile terminal can be saved; otherwise, if no shielding object exists in front of the mobile terminal, or the distance between the mobile terminal and the shielding object is greater than or equal to a preset threshold value, the mobile terminal is not close to the head of the user at the moment, the mobile terminal is not placed downwards, and the user may need to view screen information, so that the mobile terminal has screen display requirements, and the mobile terminal is kept in a bright screen state at the moment, so that user experience can be improved.
As can be seen from the above, in the mobile terminal screen control method provided by the embodiment, when the mobile terminal enters the public address communication state, whether the mobile terminal has a screen display requirement is detected, when the mobile terminal has the screen display requirement, the mobile terminal screen is kept in a bright screen state, and when the mobile terminal does not have the screen display requirement, the mobile terminal screen is controlled to be turned off, so that the energy consumption of the mobile terminal can be saved, and the user experience is improved.

Referring to fig. 4, the method for controlling a screen of a mobile terminal provided in this embodiment may include the following steps:
step S401, when the mobile terminal enters a sound amplifying communication state, starting a distance sensor arranged on the mobile terminal, and detecting whether a shielding object exists in front of the mobile terminal through the distance sensor; if a shielding object exists in front of the mobile terminal, the step S402 is entered; if no obstruction exists in front of the mobile terminal, the process goes to step S403.
Step S402, measuring the distance between the mobile terminal and the shielding object through the distance sensor, and judging whether the distance is smaller than a preset threshold value or not; if the distance is smaller than the preset threshold, the mobile terminal is indicated to have no screen display requirement, and the step S405 is skipped; if the distance is greater than or equal to the preset threshold, the process proceeds to step S403.
Step S403, controlling the front camera of the mobile terminal to collect an image in front of the mobile terminal, recognizing the image, judging whether a face image exists in the image, if so, the mobile terminal has a screen display requirement, and entering step S404 at the moment; if no face image exists in the images, the mobile terminal does not have a screen display requirement, and the step S405 is skipped.
And step S404, keeping the screen of the mobile terminal in a bright screen state.
And step S405, controlling the mobile terminal screen to be turned off.
In this embodiment, when the mobile terminal detects that there is no shielding object in front or the distance between the mobile terminal and the shielding object is greater than or equal to a preset threshold, further controlling a front camera of the mobile terminal to collect an image in front of the mobile terminal, performing face recognition on the collected image, when recognizing that a face exists in the image, indicating that a user faces a screen of the mobile terminal, and needing to view screen information, so as to keep the mobile terminal in a bright screen state, and when recognizing that there is no face in the image, indicating that the user does not face the screen of the mobile terminal, and not viewing screen information, so as to control screen deactivation of the screen of the mobile terminal. Compared with the previous embodiment, the method for judging whether the mobile terminal has the screen display requirement is more reliable, and the reliability of the screen control method of the mobile terminal is further improved.
Preferably, in this embodiment, after the face image is included in the image, the method further includes:
comparing the face image with a pre-stored face image of the mobile terminal user, and identifying whether the face image is the user;
if the user himself, the mobile terminal has a screen display requirement;
if the user is not himself, the mobile terminal has no screen display requirement.
In this embodiment, when a face is identified in the image, whether the face is the user of the mobile terminal is further determined, and the screen is kept bright only when the face is identified as the user, and when the face image is identified as not the user, the screen of the mobile terminal is controlled to be turned off, so that the reliability of the screen control method of the mobile terminal can be further improved, and the safety of the mobile terminal is improved.
As can be seen from the above, the mobile terminal screen control method provided by the embodiment can also save energy consumption of the mobile terminal and improve user experience; and, compared with the previous embodiment, the reliability of the mobile terminal screen control method is further improved due to the fact that face recognition is added when whether the mobile terminal has the screen display requirement or not is detected.
