Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an implementation flow of a sensor calibration method according to an embodiment of the present invention, where the method can be applied to the following electronic devices: the mobile terminal is provided with a built-in capacitive proximity sensor such as an SAR sensor and the like, such as a mobile phone, a tablet computer, a notebook computer and the like. As shown in fig. 1, the method mainly comprises the following steps:
s101, detecting the screen state of the mobile terminal when the capacitive proximity sensor is registered by an application;
the capacitive proximity sensor is arranged in the mobile terminal and can be used for judging whether a human face approaches the screen according to the size of the detected capacitance value.
When the mobile terminal runs various applications, some capacitive proximity sensors need to be started when the applications run, and the on-off of a screen of the mobile terminal is controlled through detection results of the capacitive proximity sensors.
When the capacitive proximity sensor is registered by the application, it indicates that the application needs to acquire detection data of the capacitive proximity sensor, and at the moment, the screen state of the mobile terminal is detected, wherein the screen state is divided into a screen-on state and a screen-off state.
And S102, if the screen state is a bright screen state, taking the capacitance value currently measured by the capacitive proximity sensor as the reference capacitance value of the capacitive proximity sensor.
If the screen state is a bright screen state, it indicates that the capacitance value currently measured by the capacitive proximity sensor may affect screen extinction, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, that is, the initial reference capacitance value of the capacitive proximity sensor is modified into the current measured capacitance value. Therefore, even if objects such as water drops and sweat exist on the screen, the capacitance value generated by the objects is calibrated in the modified reference capacitance value, and therefore the detection result of the capacitive proximity sensor cannot be influenced. Then, at the moment, the user uses the mobile terminal, for example, makes a call, and then makes a face close to the screen, and the capacitance type proximity sensor can effectively identify capacitance change caused by the approach of the face, so that correct response is made, the screen can be normally turned off during conversation, and the screen cannot be turned off by mistake.
The reference capacitance value is used for detecting whether a human face approaches the screen of the mobile terminal or not by the capacitive proximity sensor based on the value.
In the embodiment of the invention, when the capacitive proximity sensor is applied and registered, the screen state of the mobile terminal is detected, if the screen state is in a bright screen state, the reference capacitance value of the capacitive proximity sensor is calibrated, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, so that the induction error of the capacitive proximity sensor caused by the capacitance values generated by other unrelated objects when a user uses the mobile terminal is eliminated, and the accuracy of judging whether the face is close to the screen of the mobile terminal is improved.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating an implementation of a sensor calibration method according to another embodiment of the present invention, where the method can be applied to the following electronic devices: the mobile terminal is provided with a built-in capacitive proximity sensor such as an SAR sensor and the like, such as a mobile phone, a tablet computer, a notebook computer and the like. As shown in fig. 2, the method mainly includes the following steps:
s201, when the capacitive proximity sensor is registered by a new application, detecting the screen state of the mobile terminal;
when the mobile terminal runs various applications, some applications are started when running, for example, when automatic backlight is started, the capacitive proximity sensor is registered by the application and is triggered to be started. At this time, if there is an incoming call, the capacitive proximity sensor is registered again but is not turned on again. Therefore, the detection data is the result of the previous detection, and may be applied to a new application to generate errors.
The new application refers to an application registered later than the previously registered application. If the application is registered before and then the application is registered again, the application registered later is a new application. For example: the a application registers the capacitive proximity sensor before the B application, which is a new application with respect to the a application.
And S202, if the screen state is a bright screen state, taking the capacitance value currently measured by the capacitive proximity sensor as the reference capacitance value of the capacitive proximity sensor.
If the screen state is a bright screen state, it indicates that the capacitance value currently measured by the capacitive proximity sensor may affect screen extinction, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, that is, the initial reference capacitance value of the capacitive proximity sensor is modified into the current measured capacitance value. Even if there are objects such as water drops and sweat on the screen, the capacitance values generated by the objects are calibrated within the reference capacitance value, and therefore the detection result of the capacitive proximity sensor is not affected. Then, at the moment, the user uses the mobile terminal, for example, makes a call, and then makes a face close to the screen, and the capacitance type proximity sensor can effectively identify capacitance change caused by the approach of the face, so that correct response is made, the screen can be normally turned off during conversation, and the screen cannot be turned off by mistake.
If the screen is in the screen-off state, the control of the current screen state is accurate, the current reference capacitance value of the capacitive proximity sensor is kept unchanged, the reference capacitance value of the capacitive proximity sensor is not calibrated, and the screen-off state of the screen is kept.
The reference capacitance value is used for judging whether a human face approaches the screen of the mobile terminal or not by the capacitive proximity sensor based on the reference capacitance value.
In the embodiment of the invention, when the capacitive proximity sensor is registered by a new application, the screen state of the mobile terminal is detected, if the screen state is a bright screen state, the reference capacitance value of the capacitive proximity sensor is calibrated, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, so that the induction error of the capacitive proximity sensor caused by the capacitance values generated by other unrelated objects when a user uses the mobile terminal is eliminated, and the accuracy of judging whether the face is close to the screen of the mobile terminal is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating an implementation of a sensor calibration method according to another embodiment of the invention, where the method can be applied to the following electronic devices: the mobile terminal is provided with a built-in capacitive proximity sensor such as an SAR sensor and the like, such as a mobile phone, a tablet computer, a notebook computer and the like. As shown in fig. 3, the method mainly includes the following steps:
s301, when the capacitive proximity sensor is registered by a new application, comparing the registered application level with the new application level;
an application level table is set in a system of a mobile terminal, wherein an application list of registered capacitive proximity sensors and corresponding levels are recorded.
For example, the level of the talk application is higher than that of the screen anti-false touch application, which is higher than that of the auto backlight application.
And comparing the registered application grade with the new application grade, detecting the screen state of the mobile terminal if the new application grade of the registered capacitive proximity sensor is higher than the registered prior application grade, and not detecting the screen state of the mobile terminal if the new application grade of the registered capacitive proximity sensor is lower than the registered prior application grade, and not calibrating the reference capacitance value of the capacitive proximity sensor.
For example, when the automatic backlight is turned on, the capacitive proximity sensor is registered and triggered to turn on. At this time, if there is an incoming call, the capacitive proximity sensor is registered again, the level of the conversation application is higher than that of the automatic backlight application compared with the level of the automatic backlight application, and the capacitive proximity sensor is not turned on again when the conversation application is started. Therefore, the detection data is the result of the previous detection, and may cause errors when applied to the call application.
S302, if the new application level is higher than the registered application level, detecting the screen state of the mobile terminal;
when the mobile terminal runs various applications, some applications are started, for example, when automatic backlight is started, the capacitive proximity sensor is registered and triggered to be started. At this time, if there is an incoming call, the proximity sensor is registered again but is not turned on again. Therefore, the detection data is the result of the previous detection, and may be applied to a new application to generate errors.
And if the new application level is lower than the registered application level, not detecting the screen state of the mobile terminal.
S303, if the screen state is a bright screen state, taking the capacitance value currently measured by the capacitive proximity sensor as the reference capacitance value of the capacitive proximity sensor;
if the screen state is a bright screen state, it indicates that the capacitance value currently measured by the capacitive proximity sensor may affect screen extinction, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, so that even if there are water drops, sweat and other objects on the screen, the capacitance values generated by the water drops, sweat and other objects are calibrated in the reference capacitance value, and therefore the detection result of the capacitive proximity sensor cannot be affected. Then, at the moment, the user uses the mobile terminal, for example, makes a call, and then makes a face close to the screen, and the capacitance type proximity sensor can effectively identify capacitance change caused by the approach of the face, so that correct response is made, the screen can be normally turned off during conversation, and the screen cannot be turned off by mistake.
And S304, if the screen state is the screen-off state, keeping the current reference capacitance value of the capacitive proximity sensor unchanged.
If the screen is in the screen-off state, the control of the current screen state is accurate, the current reference capacitance value of the capacitive proximity sensor is kept unchanged, the reference capacitance value of the capacitive proximity sensor is not calibrated, and the screen-off state of the screen is kept.
The reference capacitance value is used for judging whether a human face approaches the screen of the mobile terminal or not by the capacitive proximity sensor based on the reference capacitance value.
In the embodiment of the invention, when the capacitive proximity sensor is registered by a higher-level application, the screen state of the mobile terminal is detected, if the screen state is in a bright screen state, the reference capacitance value of the capacitive proximity sensor is calibrated, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, so that the induction error of the capacitive proximity sensor caused by the capacitance values generated by other unrelated objects when a user uses the mobile terminal is eliminated, and the accuracy of judging whether the face is close to the screen of the mobile terminal is improved.

When the capacitive proximity sensor is registered by the application, it indicates that the application needs to acquire detection data of the capacitive proximity sensor, and at the moment, the screen state of the mobile terminal is detected, wherein the screen state is divided into a screen-on state and a screen-off state.
The calibration module 402 is configured to, if the screen state is a bright screen state, use a capacitance value currently measured by the capacitive proximity sensor as a reference capacitance value of the capacitive proximity sensor.
If the screen state is a bright screen state, it indicates that the capacitance value currently measured by the capacitive proximity sensor may affect screen extinction, and the capacitance value currently measured by the capacitive proximity sensor is used as the reference capacitance value of the capacitive proximity sensor, that is, the initial reference capacitance value of the capacitive proximity sensor is modified into the current measured capacitance value. Therefore, even if objects such as water drops and sweat exist on the screen, the capacitance value generated by the objects is calibrated in the modified reference capacitance value, and therefore the detection result of the capacitive proximity sensor cannot be influenced.
