在智能终端中， 常用的微型传感器包括： 重力加速度传感器、 电子指 南针、 环境光传感器以及接近传感器等。 其中， 接近传感器的主要功能是： 当用户接听来电或发起来电， 并将移动终端靠近耳朵时， 将液晶显示屏的 背光灯关掉， 以达到节电的目的。 In smart terminals, commonly used miniature sensors include: gravity acceleration sensors, electronic compasses, ambient light sensors, and proximity sensors. Among them, the main function of the proximity sensor is: When the user answers an incoming call or initiates an incoming call, and the mobile terminal is close to the ear, the liquid crystal display The backlight is turned off to save power.
接近传感器主要由两部分组成， 一个是红外光发射器， 另一个是红外 光接收器。 根据合理的结构设计， 红外光发射器与红外光接收器设置在靠 近移动终端听筒的位置。  The proximity sensor is mainly composed of two parts, one is an infrared light emitter and the other is an infrared light receiver. According to a reasonable structural design, the infrared light emitter and the infrared light receiver are placed close to the handset of the mobile terminal.
利用接近传感器关闭液晶显示屏背光灯的原理为： 当接听或发起来电， 且用户将移动终端靠近耳朵时， 红外光发射器发射出的红外光遇到障碍物 并反射回来， 红外光接收器接收到反射回来的红外光就会给主芯片反馈一 个信号， 主芯片来完成关闭屏幕背光的功能， 即： 将液晶显示屏的背光灯 关掉。  The principle of using the proximity sensor to turn off the backlight of the LCD screen is: When answering or initiating an incoming call, and the user brings the mobile terminal closer to the ear, the infrared light emitted by the infrared light emitter encounters an obstacle and is reflected back, and the infrared light receiver receives The reflected infrared light will send a signal to the main chip, and the main chip will complete the function of turning off the backlight of the screen, that is, turn off the backlight of the liquid crystal display.
基于此， 在本发明实施例中： 当有来电或发起通话时， 根据设置在终 端上的摄像头测量出的感光量， 判断用户是否将终端靠近耳朵， 确定用户 将终端靠近耳朵后， 关闭终端液晶显示屏的背光灯； 或者， 当有来电或发 起通话， 且收到设置在终端上的摄像头接收到反射光的消息后， 关闭终端 液晶显示屏的背光灯。  Based on this, in the embodiment of the present invention: when there is an incoming call or a call, according to the light quantity measured by the camera set on the terminal, it is determined whether the user closes the terminal to the ear, and determines that the user closes the terminal after the terminal is close to the ear. The backlight of the display screen; or, when there is an incoming call or a call, and the camera set on the terminal receives the message of reflected light, the backlight of the terminal liquid crystal display is turned off.
下面结合附图及具体实施例对本发明作进一步详细地描述。  The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
实施例一  Embodiment 1
本实施例提供的管理液晶显示屏背光灯的方法， 如图 1 所示， 包括以 下步骤：  The method for managing the backlight of the liquid crystal display provided by this embodiment, as shown in FIG. 1, includes the following steps:
步骤 101 : 当有来电或发起通话时，根据设置在终端上的摄像头测量出 的感光量， 判断用户是否将终端靠近耳朵；  Step 101: When there is an incoming call or a call is initiated, according to the amount of light measured by the camera set on the terminal, it is determined whether the user approaches the terminal to the ear;
这里， 所述摄像头为前置摄像头， 如图 2所示， 所述前置摄像头是指： 设置在终端的正面， 即： 与终端的液晶显示屏及听筒在同一侧， 且设置在 终端的顶部； 其中， 所述终端的顶部是指： 以用户正常使用时终端的位置 为参照物， ifc时终端的顶部。  Here, the camera is a front camera. As shown in FIG. 2, the front camera is disposed on the front side of the terminal, that is, on the same side of the liquid crystal display and the earpiece of the terminal, and is disposed on the top of the terminal. The top of the terminal refers to: the position of the terminal when the user is normally used as a reference, and the top of the terminal when ifc.
所述根据设置在终端上的摄像头测量出的感光量， 判断用户是否将终 端靠近耳朵， 具体为： Determining whether the user will end according to the amount of light measured by the camera set on the terminal The end is close to the ear, specifically:
判断所述摄像头测量出的感光量是否小于第一阈值， 确定小于第一阈 值后， 则认为用户已将终端靠近耳朵， 否则， 认为用户未将终端靠近耳朵。  It is determined whether the amount of light measured by the camera is less than a first threshold, and after determining that it is less than the first threshold, the user is considered to have approached the terminal to the ear; otherwise, the user is not considered to be close to the ear.
其中， 当终端所处的环境的光线充足时， 当有物体靠近终端， 即： 将 终端靠近耳朵时， 感光量会明显降低， 从而认为终端靠近了耳朵。  Wherein, when the environment of the terminal is sufficient, when an object approaches the terminal, that is, when the terminal is close to the ear, the amount of light is significantly reduced, so that the terminal is considered to be close to the ear.
可以将摄像头测量出的终端所处环境的感光量作为第一阈值。 当认为 用户未将终端靠近耳朵时， 说明用户还在使用终端的其它功能， 需要使用 液晶显示屏的背光灯， 即： 需要将液晶显示屏的背光灯处于开启状态。  The amount of light in the environment in which the terminal is measured by the camera can be used as the first threshold. When the user is not close to the ear, it indicates that the user is still using other functions of the terminal, and the backlight of the LCD screen is required, that is, the backlight of the liquid crystal display needs to be turned on.
摄像头的主要构成部分之一是光电传感器阵列， 在拍照时， 光电传感 器阵列感受到光照， 并且把接收到的光转化为电信号， 通过电信号的大小 来确定感光量的大小， 即进光量的大小。 曝光时， 根据当前感光量的大小 与曝光所要达到的目标值作比较， 通过比较的差异来调整曝光策略。 当用 户将终端靠近耳朵后， 摄像头的光电传感器阵列会检测出此时的感光量， 因此， 可以利用摄像头的光电传感器阵列所检测出的感光量的大小， 来判 断用户是否将终端靠近了耳朵。  One of the main components of the camera is a photosensor array. When photographing, the photosensor array senses the light and converts the received light into an electrical signal. The size of the light is determined by the size of the electrical signal, that is, the amount of light entering. size. When exposing, the exposure strategy is adjusted by comparing the difference according to the current sensitivity amount and the target value to be achieved by the exposure. When the user brings the terminal closer to the ear, the photosensor array of the camera detects the amount of light at this time. Therefore, the magnitude of the amount of light detected by the photosensor array of the camera can be used to determine whether the user is close to the ear.
所述用户将终端靠近耳朵是指： 用户将终端的听筒靠近耳朵。  The user placing the terminal close to the ear means that the user brings the earpiece of the terminal close to the ear.
在根据设置在终端上的摄像头测量出的感光量， 判断用户是否将终端 靠近耳朵之前， 该方法还可以包括：  The method may further include: before determining whether the user approaches the terminal to the ear according to the amount of light measured by the camera disposed on the terminal, the method may further include:
判断通话链路是否已建立， 确定通话链路已建立后， 启动所述摄像头， 使所述摄像头进入模拟传感器模式。  After determining whether the call link has been established, after determining that the call link has been established, the camera is activated to put the camera into the analog sensor mode.
其中， 判断通话链路是否已建立的具体实现可釆用现有技术。  Among them, the specific implementation of determining whether the call link has been established may use the prior art.
步骤 102：确定用户将终端靠近耳朵后，关闭终端液晶显示屏的背光灯。 这里， 本步骤的具体实现可釆用现有技术。  Step 102: After determining that the user closes the terminal to the ear, the backlight of the terminal liquid crystal display is turned off. Here, the specific implementation of this step can use the prior art.
关闭背光灯的目的是： 节约终端的电能， 保持终端的续航能力。  The purpose of turning off the backlight is to: save power of the terminal and maintain the terminal's endurance.
从上面的描述中可以看出， 本实施例利用摄像头实现目前接近传感器 所能做的工作， 釆用了尽可能少的器件完成了尽可能多的功能， 如此， 节 省了器件的布局空间和终端的整体体积， 为终端节省终端越来越大的空间 开销提供了方向。 As can be seen from the above description, the present embodiment utilizes a camera to implement the current proximity sensor. The work that can be done uses as few devices as possible to complete as many functions as possible. This saves the layout space of the device and the overall size of the terminal, providing a direction for the terminal to save more and more space for the terminal. .
另外， 先判断通话链路是否已建立， 确定通话链路已建立后， 启动所 述摄像头， 使所述摄像头进入模拟传感器模式， 再根据设置在终端上的摄 像头测量出的感光量， 判断用户是否将终端靠近耳朵， 如此， 能有效地节 约终端的电能， 使终端有较强的续航能力。  In addition, first determining whether the call link has been established, determining that the call link has been established, starting the camera, causing the camera to enter the analog sensor mode, and determining whether the user is based on the amount of light measured by the camera set on the terminal The terminal is close to the ear, so that the power of the terminal can be effectively saved, and the terminal has a strong endurance.
实施例二  Embodiment 2
当终端所处的环境的光线较弱甚至全黑时， 此时， 由于环境的光线较 弱， 摄像头测量出的感光量会相对较小， 甚至可能与终端靠近耳朵时测量 出的感光量相同， 因此， 如果仅釆用实施例一中的方法去判断用户是否将 终端靠近耳朵是不太准确的， 基于此， 本实施例提供的管理液晶显示屏背 光灯的方法， 如图 3所示， 包括以下步骤：  When the light in the environment where the terminal is located is weak or even black, at this time, because the ambient light is weak, the amount of light measured by the camera will be relatively small, and may even be the same as the amount of light measured when the terminal is close to the ear. Therefore, if only the method in the first embodiment is used to determine whether the user is close to the ear, it is not accurate. Based on this, the method for managing the backlight of the liquid crystal display provided by the embodiment, as shown in FIG. 3, includes The following steps:
步骤 101 : 当有来电或发起通话时，根据设置在终端上的摄像头测量出 的感光量， 判断用户是否将终端靠近耳朵， 确定用户未将终端靠近耳朵后， 执行步骤 102， 否则， 执行步骤 103;  Step 101: When there is an incoming call or a call, according to the amount of light measured by the camera set on the terminal, determine whether the user is close to the ear, and determine that the user does not close the terminal to the ear, go to step 102, otherwise, go to step 103. ;
这里， 所述摄像头为前置摄像头， 如图 2所示， 所述前置摄像头是指： 设置在终端的正面， 即： 与终端的液晶显示屏及听筒在同一侧， 且设置在 终端的顶部； 其中， 所述终端的顶部是指： 以用户正常使用时终端的位置 为参照物， ifc时终端的顶部。  Here, the camera is a front camera. As shown in FIG. 2, the front camera is disposed on the front side of the terminal, that is, on the same side of the liquid crystal display and the earpiece of the terminal, and is disposed on the top of the terminal. The top of the terminal refers to: the position of the terminal when the user is normally used as a reference, and the top of the terminal when ifc.
所述根据设置在终端上的摄像头测量出的感光量， 判断用户是否将终 端靠近耳朵， 具体为：  The determining whether the user brings the terminal to the ear according to the amount of light measured by the camera disposed on the terminal is specifically:
判断所述摄像头测量出的感光量是否小于第一阈值， 确定小于第一阈 值后， 则认为用户已将终端靠近耳朵， 否则， 认为用户未将终端靠近耳朵。  It is determined whether the amount of light measured by the camera is less than a first threshold, and after determining that it is less than the first threshold, the user is considered to have approached the terminal to the ear; otherwise, the user is not considered to be close to the ear.
其中， 可以将摄像头测量出的终端所处环境的感光量作为第一阈值。 摄像头的主要构成部分之一是光电传感器阵列， 在拍照时， 光电传感 器阵列感受到光照， 并且把接收到的光转化为电信号， 通过电信号的大小 来确定感光量的大小， 即进光量的大小。 曝光时， 根据当前感光量的大小 与曝光所要达到的目标值作比较， 通过比较的差异来调整曝光策略。 当用 户将终端靠近耳朵后， 摄像头的光电传感器阵列会检测出此时的感光量， 因此， 可以利用摄像头的光电传感器阵列所检测出的感光量的大小， 来判 断用户是否将终端靠近了耳朵。 Wherein, the sensitivity of the environment in which the terminal is measured by the camera can be used as the first threshold. One of the main components of the camera is a photosensor array. When photographing, the photosensor array senses the light and converts the received light into an electrical signal. The size of the light is determined by the size of the electrical signal, that is, the amount of light entering. size. When exposing, the exposure strategy is adjusted by comparing the difference according to the current sensitivity amount and the target value to be achieved by the exposure. When the user brings the terminal closer to the ear, the photosensor array of the camera detects the amount of light at this time. Therefore, the magnitude of the amount of light detected by the photosensor array of the camera can be used to determine whether the user has brought the terminal close to the ear.
步骤 102: 进一步判断终端是否有明显移动， 确定终端有明显移动后， 执行步骤 103， 否则， 执行步骤 104。  Step 102: Further determine whether the terminal has obvious movement. After determining that the terminal has obvious movement, perform step 103. Otherwise, perform step 104.
这里， 所述判断终端是否有明显移动， 具体为：  Here, the determining whether the terminal has obvious movement is specifically:
根据设置在终端上的重力传感器或陀螺仪的测量值， 判断终端是否有 明显移动。  According to the measured value of the gravity sensor or gyroscope set on the terminal, it is judged whether the terminal has obvious movement.
更具体地， 判断所述重力传感器或陀螺仪测量的测量值是否大于第二 阈值， 确定大于第二阈值后， 则认为终端有明显移动， 确定小于等于第二 阈值后， 则认为终端没有明显移动。 这里， 可以依据需要设置第二阈值。  More specifically, it is determined whether the measured value measured by the gravity sensor or the gyroscope is greater than a second threshold, and after determining that the value is greater than the second threshold, the terminal is considered to have a significant movement, and after determining that the second threshold is less than or equal to the second threshold, the terminal is considered to have no significant movement. . Here, the second threshold can be set as needed.
步骤 103: 关闭终端液晶显示屏的背光灯；  Step 103: Turn off the backlight of the terminal LCD screen;
这里， 本步骤的具体实现可釆用现有技术。  Here, the specific implementation of this step can use the prior art.
关闭背光灯的目的是： 节约终端的电能， 保持终端的续航能力。  The purpose of turning off the backlight is to: save power of the terminal and maintain the terminal's endurance.
步骤 104: 保持终端液晶显示屏的背光灯的开启状态。  Step 104: Keep the backlight of the terminal LCD screen turned on.
这里， 当确定终端没有明显移动时， 说明用户还在使用终端的其它功 能， 需要使用液晶显示屏的背光灯， 即： 需要将液晶显示屏的背光灯处于 开启状态。  Here, when it is determined that the terminal does not move significantly, it indicates that the user is still using other functions of the terminal, and the backlight of the liquid crystal display is required, that is, the backlight of the liquid crystal display needs to be turned on.
从上面的描述中可以看出， 本实施例利用摄像头实现目前接近传感器 所能做的工作， 釆用了尽可能少的器件完成了尽可能多的功能， 如此， 节 省了器件的布局空间和终端的整体体积， 为终端节省终端越来越大的空间 开销提供了方向。 As can be seen from the above description, the present embodiment utilizes the camera to achieve the work that the current proximity sensor can do, and uses as few devices as possible to complete as many functions as possible, thus saving the layout space and the terminal of the device. The overall volume, saving more and more space for the terminal The overhead provides the direction.
另外， 先判断通话链路是否已建立， 确定通话链路已建立后， 启动所 述摄像头， 使所述摄像头进入模拟传感器模式， 再根据设置在终端上的摄 像头测量出的感光量， 判断用户是否将终端靠近耳朵， 如此， 能有效地节 约终端的电能， 使终端有较强的续航能力。  In addition, first determining whether the call link has been established, determining that the call link has been established, starting the camera, causing the camera to enter the analog sensor mode, and determining whether the user is based on the amount of light measured by the camera set on the terminal The terminal is close to the ear, so that the power of the terminal can be effectively saved, and the terminal has a strong endurance.

本实施例提供的管理液晶显示屏背光灯的方法， 如图 4 所示， 包括以 下步骤：  The method for managing the backlight of the liquid crystal display provided by this embodiment, as shown in FIG. 4, includes the following steps:
步骤 401 : 当有来电或发起通话时， 判断是否收到设置在终端上的摄像 头接收到反射光的消息；  Step 401: When there is an incoming call or a call is initiated, it is determined whether a message that the camera set on the terminal receives the reflected light is received;
这里， 所述摄像头为前置摄像头， 如图 2所示， 所述前置摄像头是指： 设置在终端的正面， 即： 与终端的液晶显示屏及听筒在同一侧， 且设置在 终端的顶部； 其中， 所述终端的顶部是指： 以用户正常使用时终端的位置 为参照物， ifc时终端的顶部。  Here, the camera is a front camera.

The layout space and the overall size of the terminal provide a direction for the terminal to save more and more space overhead of the terminal.
