背景技术Background technique

Capacitive proximity sensors can be placed near the antenna area of a mobile phone to detect whether a human face is approaching by sensing capacitance.
但是电容式接近传感器会有检测错误的情况，当手机屏幕有液体产生电容，电容式接近传感器会因检测到的电容值错误地识别为人脸接近状态，导致识别异常，影响手机的正常功能。However, the capacitive proximity sensor may detect errors. When there is liquid on the mobile phone screen to generate capacitance, the capacitive proximity sensor will mistakenly recognize the face proximity state due to the detected capacitance value, resulting in abnormal recognition and affecting the normal function of the mobile phone.

为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而非全部实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, 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 in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
请参阅图1，图1为本发明一实施例提供的传感器校准方法的实现流程示意图，该方法可应用于如下电子装置中：内置有SAR传感器等电容式接近传感器的手机、平板电脑、笔记本电脑等移动终端。如图1所示，该方法主要包括以下步骤：Please refer to Fig. 1, Fig. 1 is a schematic diagram of the implementation flow of the sensor calibration method provided by an embodiment of the present invention, which can be applied to the following electronic devices: mobile phones, tablet computers, notebook computers with built-in capacitive proximity sensors such as SAR sensors and other mobile terminals. As shown in Figure 1, the method mainly includes the following steps:
S101、当电容式接近传感器被应用注册时，检测移动终端的屏幕状态；S101. When the capacitive proximity sensor is registered by the application, detect the screen state of the mobile terminal;
电容式接近传感器内置于移动终端内，可用于根据检测的电容值的大小判断是否有人脸靠近屏幕。The capacitive proximity sensor is built into the mobile terminal and can be used to judge whether a human face is close to the screen according to the detected capacitance value.
移动终端在运行各种应用时，有些与应用运行时需要开启电容式接近传感器，通过电容式接近传感器检测结果控制移动终端的屏幕的点亮和熄灭。When the mobile terminal runs various applications, some applications need to turn on the capacitive proximity sensor when the application is running, and control the lighting and extinguishing of the screen of the mobile terminal through the detection result of the capacitive proximity sensor.
当电容式接近传感器被应用注册时，表明有应用要获取电容式接近传感器的检测数据，此时检测移动终端的屏幕状态，屏幕状态分为亮屏状态和灭屏状态。When the capacitive proximity sensor is registered by the application, it indicates that there is an application to obtain the detection data of the capacitive proximity sensor. At this time, the screen state of the mobile terminal is detected, and the screen state is divided into a bright screen state and an off screen state.
S102、若屏幕状态为亮屏状态，则将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值。S102. If the screen state is a bright screen state, use the capacitance value currently measured by the capacitive proximity sensor as a reference capacitance value of the capacitive proximity sensor.
若屏幕状态为亮屏状态，表明电容式接近传感器当前测量的电容值可能影响了屏幕熄灭，将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值，即，将电容式接近传感器的初始的基准电容值修改为该当前测量的电容值。这样即便是屏幕上有水滴、汗液等物体，它们产生的电容值被校准在修改后的基准电容值内了，因此不会影响电容式接近传感器的检测结果。那么此时用户使用移动终端，例如打电话，再将脸靠近屏幕，电容式接近传感器就可以有效地识别到人脸靠近导致的电容变化，从而做出正确的响应，那么通话时就会正常灭屏，不会误灭屏。If the screen status is bright, it indicates that the capacitance value currently measured by the capacitive proximity sensor may have affected the screen being turned off. 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 capacitive proximity sensor The sensor's initial baseline capacitance value is modified to the current measured capacitance value. In this way, even if there are water droplets, sweat and other objects on the screen, the capacitance value generated by them is calibrated within the modified reference capacitance value, so the detection result of the capacitive proximity sensor will not be affected. At this time, when the user uses the mobile terminal, such as making a phone call, and then puts his face close to the screen, the capacitive proximity sensor can effectively recognize the capacitance change caused by the approach of the face, so as to make a correct response, then it will normally turn off during the call. screen, the screen will not be turned off by mistake.
基准电容值是指电容式接近传感器以此值为基础，对是否有人脸接近移动终端屏幕进行检测。The reference capacitance value means that the capacitive proximity sensor detects whether a human face approaches the screen of the mobile terminal based on this value.
本发明实施例中，当电容式接近传感器被应用注册时，检测移动终端的屏幕状态，若屏幕状态为亮屏状态，则校准电容式接近传感器的基准电容值，将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值，以此消除由于在用户使用移动终端时，其他无关物体产生的电容值造成电容式接近传感器的感应误差，提高判断人脸是否接近移动终端屏幕的准确率。In the embodiment of the present invention, when the capacitive proximity sensor is registered by the 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 capacitive proximity sensor is currently measured. The capacitance value is used as the reference capacitance value of the capacitive proximity sensor, so as to eliminate the sensing error of the capacitive proximity sensor caused by the capacitance value generated by other irrelevant objects when the user uses the mobile terminal, and improve the accuracy of judging whether the face is close to the mobile terminal screen Rate.
请参阅图2，图2为本发明另一实施例提供的传感器校准方法的实现流程示意图，该方法可应用于如下电子装置中：内置有SAR传感器等电容式接近传感器的手机、平板电脑、笔记本电脑等移动终端。如图2所示，该方法主要包括以下步骤：Please refer to Fig. 2, Fig. 2 is a schematic diagram of the implementation process of the sensor calibration method provided by another embodiment of the present invention, which can be applied to the following electronic devices: mobile phones, tablet computers, notebooks with built-in capacitive proximity sensors such as SAR sensors Computers and other mobile terminals. As shown in Figure 2, the method mainly includes the following steps:
S201、当电容式接近传感器被新的应用注册时，检测移动终端的屏幕状态；S201. When the capacitive proximity sensor is registered by a new application, detect the screen state of the mobile terminal;
移动终端在运行各种应用时，有些应用运行时开启电容式接近传感器，例如开启自动背光时，电容式接近传感器是被应用注册并触发开启了。此时如果有来电，那么电容式接近传感器虽然再次被注册，但并不会再次被开启。因此检测数据是前一次检测的结果，应用到新的应用上，可能会产生错误。When the mobile terminal runs various applications, some applications turn on the capacitive proximity sensor when running. For example, when the automatic backlight is turned on, the capacitive proximity sensor is registered by the application and triggered to turn on. If there is an incoming call at this time, although the capacitive proximity sensor is registered again, it will not be turned on again. Therefore, the detection data is the result of the previous detection, and when applied to a new application, errors may occur.
新的应用是指晚于之前已注册的应用注册的应用。之前已注册有应用，之后又有应用注册，则之后注册的应用为新的应用。例如：A应用在B应用之前注册电容式接近传感器，则B应用相对于A应用为新的应用。A new application is one that is registered later than a previously registered application. If an application has been registered before, and another application is registered later, the application registered after that is a new application. For example: Application A registers the capacitive proximity sensor before application B, then application B is a new application relative to application A.
S202、若屏幕状态为亮屏状态，则将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值。S202. If the screen state is a bright screen state, use the capacitance value currently measured by the capacitive proximity sensor as a reference capacitance value of the capacitive proximity sensor.
若屏幕状态为亮屏状态，表明电容式接近传感器当前测量的电容值可能影响了屏幕熄灭，将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值，即，将电容式接近传感器的初始的基准电容值修改为该当前测量的电容值。这样即便是屏幕上有水滴、汗液等物体，它们产生的电容值被校准在基准电容值内了，因此不会影响电容式接近传感器的检测结果。那么此时用户使用移动终端，例如打电话，再将脸靠近屏幕，电容式接近传感器就可以有效地识别到人脸靠近导致的电容变化，从而做出正确的响应，那么通话时就会正常灭屏，不会误灭屏。If the screen status is bright, it indicates that the capacitance value currently measured by the capacitive proximity sensor may have affected the screen being turned off. 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 capacitive proximity sensor The sensor's initial baseline capacitance value is modified to the current measured capacitance value. In this way, even if there are water droplets, sweat and other objects on the screen, the capacitance value generated by them is calibrated within the reference capacitance value, so it will not affect the detection result of the capacitive proximity sensor. At this time, when the user uses the mobile terminal, such as making a phone call, and then puts his face close to the screen, the capacitive proximity sensor can effectively recognize the capacitance change caused by the approach of the face, so as to make a correct response, then it will normally turn off during the call. screen, the screen will not be turned off by mistake.
若屏幕为灭屏状态，表示当前屏幕状态的控制是准确的，则保持电容式接近传感器的当前基准电容值不变，不对电容式接近传感器的基准电容值进行校准，保持屏幕的灭屏状态。If the screen is in the off-screen state, it means that the control of the current screen state is accurate, then keep the current reference capacitance value of the capacitive proximity sensor unchanged, do not calibrate the reference capacitance value of the capacitive proximity sensor, and keep the screen in the off-screen state.
基准电容值是指电容式接近传感器以此基准电容值为基础，判断是否有人脸接近移动终端屏幕。The reference capacitance value means that the capacitive proximity sensor judges whether a human face approaches the screen of the mobile terminal based on the reference capacitance value.
本发明实施例中，当电容式接近传感器被新的应用注册时，检测移动终端的屏幕状态，若屏幕状态为亮屏状态，则校准电容式接近传感器的基准电容值，将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值，以此消除由于在用户使用移动终端时，其他无关物体产生的电容值造成电容式接近传感器的感应误差，提高判断人脸是否接近移动终端屏幕的准确率。In the embodiment of the present invention, when the capacitive proximity sensor is registered by a new application, the screen state of the mobile terminal is detected, and if the screen state is a bright screen state, the reference capacitance value of the capacitive proximity sensor is calibrated, and the capacitive proximity sensor is currently The measured capacitance value is used as the reference capacitance value of the capacitive proximity sensor, so as to eliminate the sensing error of the capacitive proximity sensor caused by the capacitance value generated by other irrelevant objects when the user uses the mobile terminal, and improve the judgment of whether the face is close to the mobile terminal screen the accuracy rate.
请参阅图3，图3为本发明另一实施例提供的传感器校准方法的实现流程示意图，该方法可应用于如下电子装置中：内置有SAR传感器等电容式接近传感器的手机、平板电脑、笔记本电脑等移动终端。如图3所示，该方法主要包括以下步骤：Please refer to Fig. 3, Fig. 3 is a schematic diagram of the implementation flow of the sensor calibration method provided by another embodiment of the present invention, which can be applied to the following electronic devices: mobile phones, tablet computers, notebooks with built-in capacitive proximity sensors such as SAR sensors Computers and other mobile terminals. As shown in Figure 3, the method mainly includes the following steps:
S301、当电容式接近传感器被新的应用注册时，对比已注册的应用等级和新的应用等级；S301. When the capacitive proximity sensor is registered by a new application, compare the registered application level with the new application level;
在移动终端的系统中设置一个应用等级表，其中记录有注册电容式接近传感器的应用名单以及对应的等级。An application level table is set in the system of the mobile terminal, which records the list of applications registered with the capacitive proximity sensor and the corresponding levels.
例如，通话应用的等级高于屏幕防误触应用的等级，屏幕防误触应用的等级高于自动背光应用的等级。For example, the level of the calling application is higher than that of the screen anti-mistouch application, and the level of the screen anti-mistouch application is higher than that of the automatic backlight application.
对比已注册的应用等级和新的应用等级，如果注册电容式接近传感器的新的应用等级高于已注册在先的应用等级，则检测移动终端屏幕状态，如果注册电容式接近传感器的新的应用等级低于于已注册在先的应用等级，则不检测移动终端屏幕状态的步骤，不校准电容式接近传感器的基准电容值。Compare the registered application level with the new application level, if the new application level of the registered capacitive proximity sensor is higher than the previously registered application level, then detect the screen status of the mobile terminal, if the new application level of the registered capacitive proximity sensor If the level is lower than the previously registered application level, the step of detecting the screen state of the mobile terminal is not performed, and the reference capacitance value of the capacitive proximity sensor is not calibrated.
例如开启自动背光时，电容式接近传感器是被注册并触发开启了。此时如果有来电，那么电容式接近传感器再次被注册，对比自动背光应用和通话应用的等级，通话应用等级高于自动背光应用，则在启用通话应用时不会再次开启电容式接近传感器。因此检测数据是前一次检测的结果，应用到通话应用上，可能会产生错误。For example, when the automatic backlight is turned on, the capacitive proximity sensor is registered and triggered to turn on. If there is an incoming call at this time, then the capacitive proximity sensor is registered again. Compared with the level of the automatic backlight application and the call application, the level of the call application is higher than that of the automatic backlight application, and the capacitive proximity sensor will not be turned on again when the call application is enabled. Therefore, the detection data is the result of the previous detection, and when applied to the call application, errors may occur.
S302、若新的应用等级高于已注册的应用等级，则检测移动终端的屏幕状态；S302. If the new application level is higher than the registered application level, then detect the screen state of the mobile terminal;
移动终端在运行各种应用时，有些应用运行时开启电容式接近传感器，例如开启自动背光时，电容式接近传感器是被注册并触发开启了。此时如果有来电，那么接近传感器虽然再次被注册，但并不会再次被开启。因此检测数据是前一次检测的结果，应用到新的应用上，可能会产生错误。When the mobile terminal runs various applications, some applications turn on the capacitive proximity sensor when running, for example, when the automatic backlight is turned on, the capacitive proximity sensor is registered and triggered to be turned on. If there is an incoming call at this time, although the proximity sensor is registered again, it will not be turned on again. Therefore, the detection data is the result of the previous detection, and when applied to a new application, errors may occur.
若新的应用等级低于已注册的应用等级，则不检测移动终端的屏幕状态。If the new application level is lower than the registered application level, the screen state of the mobile terminal is not detected.
S303、若屏幕状态为亮屏状态，则将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值；S303. If the screen state is a bright screen state, use the capacitance value currently measured by the capacitive proximity sensor as the reference capacitance value of the capacitive proximity sensor;
若屏幕状态为亮屏状态，表明电容式接近传感器当前测量的电容值可能影响了屏幕熄灭，将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值，这样即便是屏幕上有水滴、汗液等物体，它们产生的电容值被校准在基准电容值内了，因此不会影响电容式接近传感器的检测结果。那么此时用户使用移动终端，例如打电话，再将脸靠近屏幕，电容式接近传感器就可以有效地识别到人脸靠近导致的电容变化，从而做出正确的响应，那么通话时就会正常灭屏，不会误灭屏。If the screen status is bright, it means that the capacitance value currently measured by the capacitive proximity sensor may affect the screen being turned off. 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 the screen has For objects such as water droplets and sweat, the capacitance value generated by them is calibrated within the reference capacitance value, so it will not affect the detection result of the capacitive proximity sensor. At this time, when the user uses the mobile terminal, such as making a phone call, and then puts his face close to the screen, the capacitive proximity sensor can effectively recognize the capacitance change caused by the approach of the face, so as to make a correct response, then it will normally turn off during the call. screen, the screen will not be turned off by mistake.
S304、若屏幕状态为灭屏状态，则保持电容式接近传感器的当前基准电容值不变。S304. If the screen state is the off-screen state, keep the current reference capacitance value of the capacitive proximity sensor unchanged.
若屏幕为灭屏状态，表示当前屏幕状态的控制是准确的，则保持电容式接近传感器的当前基准电容值不变，不对电容式接近传感器的基准电容值进行校准，保持屏幕的灭屏状态。If the screen is in the off-screen state, it means that the control of the current screen state is accurate, then keep the current reference capacitance value of the capacitive proximity sensor unchanged, do not calibrate the reference capacitance value of the capacitive proximity sensor, and keep the screen in the off-screen state.

The electronic device illustrated in FIG. 5 differs from the electronic device in the embodiment shown in FIG. 4 mainly in that:
进一步的，检测模块401，还用于当电容式接近传感器被新的应用注册时，检测移动终端的屏幕状态；Further, the detection module 401 is also used to detect the screen state of the mobile terminal when the capacitive proximity sensor is registered by a new application;
新的应用是指晚于之前已注册的应用注册的应用。A new application is one that is registered later than a previously registered application.
检测模块401还进一步地包括：The detection module 401 further includes:
对比子模块4011，用于当电容式接近传感器被新的应用注册时，对比已注册的应用等级和新的应用等级；The comparison sub-module 4011 is used to compare the registered application level and the new application level when the capacitive proximity sensor is registered by a new application;
在移动终端的系统中设置一个应用等级表，其中记录有注册电容式接近传感器的应用名单以及对应的等级。An application level table is set in the system of the mobile terminal, which records the list of applications registered with the capacitive proximity sensor and the corresponding levels.
例如，通话应用的等级高于屏幕防误触应用的等级，屏幕防误触应用的等级高于自动背光应用的等级。For example, the level of the calling application is higher than that of the screen anti-mistouch application, and the level of the screen anti-mistouch application is higher than that of the automatic backlight application.
检测子模块4012，用于若新的应用等级高于已注册的应用等级，则检测移动终端的屏幕状态。The detection sub-module 4012 is used to detect the screen state of the mobile terminal if the new application level is higher than the registered application level.
校准模块402，还用于若屏幕状态为灭屏状态，则保持电容式接近传感器的当前基准电容值不变。The calibration module 402 is further configured to keep the current reference capacitance value of the capacitive proximity sensor unchanged if the screen state is off.
本实施例未尽之细节，请参阅前述图1至图4所示实施例的描述，此处不再赘述。For the details not covered in this embodiment, please refer to the description of the embodiment shown in FIG. 1 to FIG.
本发明实施例中，当电容式接近传感器被应用注册时，检测移动终端的屏幕状态，若屏幕状态为亮屏状态，则校准电容式接近传感器的基准电容值，将电容式接近传感器当前测量的电容值作为电容式接近传感器的基准电容值，以此消除由于在用户使用移动终端时，其他无关物体产生的电容值造成电容式接近传感器的感应误差，提高判断人脸是否接近移动终端屏幕的准确率。In the embodiment of the present invention, when the capacitive proximity sensor is registered by the 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 capacitive proximity sensor is currently measured. The capacitance value is used as the reference capacitance value of the capacitive proximity sensor, so as to eliminate the sensing error of the capacitive proximity sensor caused by the capacitance value generated by other irrelevant objects when the user uses the mobile terminal, and improve the accuracy of judging whether the face is close to the mobile terminal screen Rate.
