Fig. 2 is a flowchart of a screen control method according to an embodiment of the present invention. The screen control method is applicable to the electronic device 1 shown in fig. 1. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.
In step S10, when the electronic device 1 enters the talk mode, the proximity sensor 50 and the first temperature sensor 60 are activated.
Specifically, the call mode includes answering an incoming call or initiating a call. When the electronic device 1 enters the call mode, the proximity sensor 50 and the first temperature sensor 60 are activated, so that the proximity sensor 50 and the first temperature sensor 60 start to acquire sensing information.
The proximity sensor 50 is used to determine whether there is a blocking object in front of the screen 40 of the electronic device 1 and output proximity sensing information.
In one embodiment, the proximity sensor 50 includes an infrared emitter and an infrared receiver, the infrared emitter is configured to emit infrared rays outwards, the infrared receiver is configured to receive infrared rays reflected by an object, a distance between the object and the proximity sensor 50 can be determined by measuring intensity of the infrared rays reflected by the object, and a stronger intensity of the received infrared rays indicates a smaller distance between the object and the object. In another embodiment, the distance between the proximity sensor 50 and the object may also be calculated by the time difference between the infrared light emitted by the infrared emitter and the infrared light received by the infrared receiver.
Typically, the obstruction is, but not limited to, a face or a finger. When the mask is a face, it may be forehead, ear or cheek. It will be appreciated that the covering may also be a glove, stylus, etc.
The first temperature sensor 60 is used for sensing the temperature of the shielding object and outputting first temperature information.
In step S20, the proximity sensing information output by the proximity sensor 50 and the first temperature information output by the first temperature sensor 60 are acquired.
Specifically, the proximity sensing information is used to feed back whether a blocking object is blocked in front of the screen 40. In the present embodiment, it is determined that there is a blocking object in front of the screen 40 only when the blocking object is close to the screen 40 (for example, the distance is less than 5 cm). The first temperature information may be used to determine whether the obstruction is a face of a user.
Step S30, determining whether there is a shelter in front of the screen 40 according to the proximity sensing information, and controlling the screen state of the electronic device 1 according to the first temperature information.
The screen states include a lit state and an off state. When the screen state is the off-screen state, the screen 40 no longer displays information, which can prevent the user's face from touching the screen 40 by mistake and can save the electric power of the electronic device 1.
Specifically, the screen state of the electronic device 1 is controlled to be a display state or a screen off state according to the proximity sensing information and the first temperature information. Whether a shielding object is shielded in front of the screen 40 can be fed back by the proximity sensing information, and the temperature of the shielding object can be fed back by the first temperature information, so that whether the shielding object is a shielding object related to the screen extinguishing state, such as a face, can be judged by combining the proximity sensing information and the first temperature information, and the screen state of the electronic device 1 is controlled.
For example, if it can be determined that the blocking object is a face according to the proximity sensing information and the first temperature information, the screen state of the electronic device 1 is controlled to be a screen-off state. When the electronic device 1 enters the talk mode, the screen state is usually the bright screen state, and at this time, the screen state needs to be switched to the off screen state.
For another example, if it can be determined that the shielding object is not a face according to the proximity sensing information and the first temperature information, the screen state of the electronic device 1 is controlled to be a bright screen state. Since the screen state of the electronic device 1 is usually a bright screen state when entering the talk mode, it is only necessary to keep the screen 40 in the display state.
The screen control method combines the proximity sensing information and the first temperature information to control the screen state of the electronic device 1. After the electronic device 1 enters a call state, whether a shielding object exists in front of the proximity sensing information feedback screen 40 or not is determined, and the temperature of the shielding object is fed back by the first temperature information, so as to identify whether the shielding object is a shielding object related to a screen extinguishing state, such as a face, therefore, the method can control the screen 40 to be extinguished when the shielding object exists in front of the screen 40, otherwise, the screen is kept on being lighted, the electric quantity of the electronic device 1 can be saved, the screen 40 is prevented from being touched by the face by mistake, and inconvenience caused by screen extinguishing due to mistaken starting can be avoided, therefore, the screen control method can accurately adapt to the requirements of users, and the use convenience of the electronic device 1 is improved.
In some embodiments, after step S30, the method further comprises:
continuously acquiring the proximity sensing information output by the proximity sensor 50 and the first temperature information output by the first temperature sensor 60;
and keeping or switching the screen state of the electronic equipment 1 according to the proximity sensing information and the first temperature information.
The shielding object in front of the screen can be continuously monitored through the steps so as to control the screen state of the electronic equipment 1.
For example, if there is no more shielding object before the proximity sensing information feedback screen 40, the screen state of the electronic device 1 may be switched from the off-screen state to the on-screen state; for another example, if the proximity sensing information feeds back that a blocking object is close to the screen 40, the screen state of the electronic device 1 can be switched from a bright screen state to a dark screen state; for another example, if the acquired proximity sensing information and the first temperature information remain unchanged, the current screen state of the electronic device 1 continues to be maintained.
It is understood that the method may be ended after the electronic device 1 ends the talk mode.
Referring to fig. 3, in an embodiment, the method for controlling the screen status of the electronic device 1 (step S30) includes the following steps:
step S31: whether a blocking object exists in front of the screen 40 is determined according to the proximity sensing information.
In one embodiment, if the value of the proximity sensing information is yes (Y) or no (N), in step S31, it may be determined whether there is an obstruction in front of the screen directly from the proximity sensing information. In another embodiment, the proximity sensing information may also be a distance between the shielding object and the screen, and step S31 is to compare the distance between the shielding object and the screen with a preset proximity distance to determine whether there is a shielding object in front of the screen. The predetermined approach distance is, for example, 0cm to 5cm, but is not limited thereto.
If there is no blocking object, the process proceeds to step S32, and the screen state of the electronic device 1 is controlled to be the display state.
Since there is no shielding object in front of the screen 40 in the call mode, it is not necessary to prevent the false touch at this time, and the screen state is controlled to display the state.
If the shielding object exists, the process proceeds to step S33, and the screen status of the electronic device 1 is controlled according to the first temperature information.
When the shielding object is judged to be present, whether the shielding object is the shielding object related to the screen extinguishing state, such as a face, needs to be judged according to the first temperature information.
It can be understood that, determining whether there is a shielding object in front of the screen according to the proximity sensing information may form a first determination condition, and the first temperature information becomes a second determination condition, and when controlling the screen state, the determination may be performed by combining the first determination condition and the second determination condition, and is not limited to the step sequence shown in fig. 2. In an embodiment, the step S33 "controlling the screen state of the electronic device 1 according to the first temperature information" includes:
comparing the first temperature information with a preset face temperature range to judge whether the shelter is a face or not;
when the shielding object is judged to be the face, controlling the screen to be in a screen-off state;
and when the non-face part of the shielding object is judged, controlling the screen state to be a bright screen state.
Specifically, the first temperature information is compared with a preset face temperature range, and if the first temperature information is within the face temperature range, the shelter is judged to be a face; otherwise, judging that the obstruction is not a face.
In a normal state, the temperature of the face of the human body is kept in a preset temperature range relatively constantly, so that whether the shielding object is the face or not can be judged by comparing the first temperature information with the preset face temperature range. When the shielding object is judged to be the face, the screen state is controlled to be the screen-off state, so that the screen 40 is prevented from being touched by mistake by the face, and meanwhile, the energy consumption and the electric quantity of the electronic equipment 1 are saved.
If the obstruction is not facial, for example, the obstruction can be a finger, a glove, a stylus, etc., the user may need to touch the touch screen 40 to operate the electronic device 1, for example, the touch screen 40 to search for new information, and then the screen status needs to be controlled to be bright, so as not to affect the normal use of the user.
Further, in an embodiment, the method further comprises:
simultaneously activating the second temperature sensor 70 when activating the proximity sensor 50 and the first temperature sensor 60, the second temperature sensor 70 being used to sense the ambient temperature;
acquiring second temperature information output by the second temperature sensor 70;
and matching the second temperature information with a plurality of facial temperature ranges in a preset human body temperature database to obtain the corresponding facial temperature ranges.
Because the temperature of the human face is related to the ambient temperature, the facial temperature range corresponding to the current environment can be obtained by matching the second temperature information with a plurality of facial temperature ranges in a preset human body temperature database, so that the accuracy of the screen control method is improved.
In another embodiment, the step S33 "controlling the screen state of the electronic device 1 according to the first temperature information" includes:
comparing the first temperature information with a preset face temperature range and a preset finger temperature range to judge that the shielding object is a face or a finger;
when the shielding object is judged to be the face, controlling the screen to be in a screen-off state;
and when the shielding object is judged to be a finger, controlling the screen to be in a bright screen state.
Since there is a preset difference range (e.g., 2 to 3 ℃) between the face temperature range and the finger temperature range of the human body under normal conditions, it can be specifically determined that the blocking object is a face or a finger by comparing the first temperature information with the preset face temperature range and finger temperature range, thereby performing a corresponding screen state. The preset difference range is suitable for normal situations, and abnormal situations such as sick fever or sauna of the user are eliminated.
Further, in an embodiment, the method further comprises:
simultaneously activating the second temperature sensor 70 while activating the proximity sensor 50 and the first temperature sensor 60;
acquiring second temperature information output by the second temperature sensor 70;
and matching the second temperature information with a plurality of facial temperature ranges and a plurality of finger temperature ranges in a preset human body temperature database to obtain the corresponding facial temperature ranges and finger temperature ranges.
