具体实施方式
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描述。
图1示出了本发明实施例提供的电子设备100，包括：触摸屏110、指纹模组120、主处理器130和协处理器140。
该触摸屏110可以具有指纹检测区域，更具体地，指纹模组120的有效检测范围可以至少部分位于触摸屏110的触摸区域，比如，指纹模组120可以整体地设置在触摸屏110的下方从而实现与触摸屏110的部分触摸区域重叠设置，其中，可选地，触摸屏110覆盖指纹模组120的区域便可以作为上述指纹检测区域，但本发明实施例对此不做限定。对该指纹检测区域的触摸事件可以触发指纹识别流程，可选地，该指纹检测区域可以包括该触摸屏110的一部分，例如位于该触摸屏110的上部或下部，或者也可以覆盖该触摸屏110的整个屏幕，但本发明实施例不限于此。
作为一种具体的实施例，触摸屏110可以为集成触控检测和显示功能的触控显示屏，比如其可以包括触摸传感器和显示面板，其中，可选地，触摸传感器可以外挂式地设置在显示面板上方、部分集成在显示面板或者一体集成在显示面板的内部。可选地，触摸传感器的触摸区域与显示面板的显示区域可以至少部分相互重叠，且指纹模组120的有效检测范围可以位于显示面板的显示区域之中，比如采用屏内(In display)或者屏下(Under display)结构，从而实现屏内指纹检测功能或屏下指纹检测功能。可选地，指纹模组 120可以包括指纹传感器，指纹传感器可以为电容式指纹传感器、超声波指纹传感器或者光学指纹传感器；当指纹模组120采用光学指纹传感器时，其可以复用显示面板的部分功能，比如显示面板的部分显示像素可以作为光学指纹传感器的光源，但本发明实施例不限于此。
该指纹模组120可以用于采集该触摸屏110的多个像素点的数据，其中，该多个像素点可以为位于该触摸屏110的至少一部分触摸区域的像素点。作为一个例子，该指纹模组120可以用于采集触摸屏110的指纹检测区域内的数据。可选地，该数据可以包括该指纹检测区域内的多个像素点中每个像素点的数值，该数值可以是电容参数值、光学参数值或其他数值，但本发明实施例不限于此。
为了便于理解，下面将该指纹模组120在像素点被触摸/按压时采集到的数值称为触摸数值，将该指纹模组120在像素点没有被触摸/按压时采集到的数值称为基准数值，但本发明实施例不限于此。
在本发明实施例中，该电子设备100在包括主处理器130的基础上，还可以通过协处理器140来判断触摸屏110的触摸/按压检测来实现设备整体功耗降低，其中，可选地，该主处理器130可以具体为应用处理器(Application Processor，AP)，该协处理器140可以具体为微控制单元(Micro Controller Unit，MCU)，但本发明实施例不限于此。
可选地，该协处理器140可以检测触摸屏110的触摸/按压事件，并确定该触摸/按压事件为误触还是有效手指触摸/按压。其中，该协处理器140可以仅在主处理器130处于休眠状态(即低频低功耗模式)时，检测触摸屏110的触摸/按压事件，或者也可以在该主处理器130处于休眠状态和工作状态时，均检测触摸屏110的触摸/按压事件。例如，如果该电子设备100的触摸屏110熄灭，则该主处理器130可以进入休眠状态，该协处理器140启动触摸屏110的触摸/按压事件的检测，但本发明实施例不限于此。
可选地，如果确定该触摸/按压事件是误触，则该协处理器140可以终止对该触摸/按压事件的处理，并继续检测该触摸屏110上的触摸事件。可选地，如果确定该触摸/按压事件是有效手指触摸/按压，则该协处理器140可以唤醒该主处理器130执行指纹识别流程，也就是说，协处理器140只有在确定该触摸/按压事件不是误触时，才会唤醒主处理器130，能够避免由于误触频繁唤醒主处理器130，从而有利于进一步降低设备功耗，提高设备待机时间， 进而提高用户体验。
此外，本发明实施例提供的电子设备100，通过包括主处理器130和协处理器140，该协处理器140在主处理器130处于休眠状态时检测触摸屏110的触摸/按压事件，能够在指纹模组120不具有手指检测功能且系统休眠的情况下实现低功耗手指检测。
图2示例性地示出了本发明实施例提供的电子设备100的架构示例的示意图，其中，该电子设备100可以包括触摸屏(Touch Panel，TP)110、AP、MCU和指纹模组120(FingerPrint module，FP)。具体地，该触摸屏110可以包括电容式触摸传感器或电阻式触摸传感器。该指纹模组120可以具体包括光学、电容或超声波式的指纹传感器。AP可以作为主控，主要负责系统的大部分计算工作。MCU可以作为传感器集线器(Sensor Hub)，可以获取、整合并处理来自不同传感器(例如上述触摸传感器和/或指纹传感器)的数据。MCU和AP都可以具有访问电子设备100的内存(例如动态随机存取存储器(Dynamic Random Access Memory，DRAM))的能力。
可选地，如图2所示，该AP和MCU可以通过相同的串行外设接口(Serial Peripheral Interface，SPI)总线与指纹模组120连接，并且可以通过相同的内部集成电路(Inter-Integrated Circuit，I2C)总线与触摸屏110连接。可选地，AP和MCU也可以通过相同的中断线与TP连接，和/或通过相同的中断线与FP连接。可选地，AP和MCP可以是各自独立的设备，或者AP和MCU也可以集成到片上系统(System On a Chip，SOC)中，但本发明实施例不限于此。
图3为本发明实施例提供的电子设备100的一个示例的正视图。该电子设备100可以具体为智能手机、平板电脑或者其他智能移动终端，其包括具有指纹检测区域的触摸屏110、位于触摸屏110之下的指纹模组120、位于触摸屏110之上的玻璃盖板和设备边框，但本发明实施例不限于此。
在本发明实施例中，该协处理器140可以通过多种方式检测触摸屏110上的触摸/按压事件。可选地，该MCU可以通过中断引脚或I2C接口轮询的方式确定触摸屏110上是否有触摸事件的发生，但本发明实施例不限于此。
在本发明实施例中，该协处理器140可以通过多种方式确定检测到的触摸/按压事件是否为误触。作为一个可选实施例，该协处理器140可以获取指纹模组120采集到的与该触摸/按压事件对应的触摸数据，并根据该触摸数 据，确定该触摸/按压事件是否为误触。其中，可选地，该触摸数据可以是该指纹模组120在该协处理器140确定触摸/按压事件的发生之后采集到的，例如，该协处理器140在确定触摸屏110上发生触摸/按压事件时，可以指示该指纹模组120采集该触摸/按压事件对应的触摸数据，但本发明实施例不限于此。
作为另一个可选实施例，如果该指纹模组120用于采集指纹检测区域的数据，则该协处理器140可以在检测到触摸/按压事件时，确定该触摸/按压事件是否为指纹检测区域内的触摸/按压，即确定该触摸/按压事件的触摸位置是否位于该指纹检测区域内。可选地，如果确定该触摸位置位于该指纹检测区域内，则可以指示指纹模组120进行触摸数据的采集。可选地，如果该触摸位置不位于该指纹检测区域内，则可以终止对该触摸/按压事件的处理，但本发明实施例不限于此。
在本发明实施例中，可选地，该协处理器140可以根据该指纹模组120采集到的触摸数据，确定该触摸屏110的多个像素点在触摸/按压发生前后的参数变化，例如电容参数或者光学参数的变化，并据此确定该触摸/按压事件是否为误触。例如，该协处理器140可以获取该触摸数据对应的基准数据，并根据该触摸数据和该基准数据，确定该触摸/按压事件是否为误触。其中，该基准数据可以与该触摸数据对应相同的像素点集合，并且是在该像素点集合中的像素点未被触摸时采集到的。例如，该基准数据可以包括该指纹检测区域内的多个像素点的基准数值，并且是在该指纹检测区域未被触摸时采集到，但本发明实施例不限于此。
在本发明实施例中，该基准数据可以由该协处理器140或者由该主处理器130预先获取并存储在存储器中，例如，该主处理器或协处理器可以在确定触摸屏的多个像素点(例如指纹检测区域内的多个像素点)没有被触摸/按压时，指示指纹模组采集该多个像素点的数据，并获取指纹模组根据指示采集到的数据。此时，该协处理器140可以从该存储器中获取存储的该基准数据。作为一个例子，该主处理器130可以在处于工作状态时预先从指纹模组获取该多个像素点中每个像素点的基准数值，并将获取到的基准数据存储到与协处理器140共享的存储器中。作为另一个例子，该协处理器140可以预先从指纹模组获取基准数据，并将获取到的该基准数据存储至该协处理器140专有的存储器或者与该主处理器130共享的存储器中，本发明实施例不 限于此。
可选地，该主处理器130或协处理器140可以确定该触摸屏110上是否有触摸/按压事件的发生，或者，确定该触摸屏110的特定区域(例如指纹检测区域)中是否有触摸/按压事件的发生。可选地，如果确定存在触摸/按压事件，则可以继续检测，直到确定该触摸屏110或该触摸屏110的特定区域不存在触摸/按压事件。可选地，如果确定不存在触摸/按压事件，则可以通过指纹模组120采集基准数据，但本发明实施例不限于此。
可选地，该协处理器140可以通过比较该触摸数据和该触摸数据对应的基准数据，确定该触摸/按压事件是否为误触。例如，该协处理器140可以通过比较该多个像素点中的部分或全部像素点的触摸数值和基准数值，确定该多个像素点中的有效触摸点，并根据该有效触摸点在该多个像素点中所占的比例，确定该触摸/按压事件是否为误触。
作为一个例子，该协处理器140可以比较该指纹检测区域中的第一区域中每个像素点的触摸数值和基准数值，确定该第一区域中的有效触摸点的数量，并根据该第一区域中的有效触摸点在该第一区域中的总像素点中所占的比例是否满足预设条件，确定该触摸/按压事件是误触还是有效手指触摸/按压。可选地，该第一区域可以是该指纹检测区域中的一部分，或者也可以是该指纹检测区域中的全部区域，本发明实施例不限于此。该预设条件可以是协议定义的，或者是用户预先指定的，例如，该预设条件可以是大于第一阈值且小于第二阈值，但本发明实施例不限于此。
可选地，该协处理器140可以通过多种方式确定该第一区域的有效触摸点的数量。作为一个例子，该协处理器140可以根据该第一区域中的每个像素点的触摸数值和基准数值，确定该第一区域的有效触摸阈值。例如，该有效触摸阈值可以是由下式确定的参数BR1的函数：
Figure PCTCN2017080792-appb-000003
其中，B(x,y)为该第一区域中的像素点(x,y)的基准数值，R(x,y)为像素点(x,y)的触摸数值，abs()表示求绝对值，∑x,y表示对该第一区域中的多个像素点求和，L为该多个像素点的数量。可选地，该多个像素点可以为该第一区域的所有或部分像素点，但本发明实施例不限于此。
可选地，该有效触摸阈值TH1可以等于BR1，或者可以是通过对BR1 进行运算得到的，本发明实施例不限于此。该协处理器140可以确定该第一区域中每个像素点的触摸数值与基准数值的差值的绝对值是否超过该有效触摸阈值。可选地，如果超过该有效触摸阈值，则该协处理器140可以确定该像素点为有效触摸点。反之，如果未超过该有效触摸阈值，则该协处理器140可以确定该像素点不是有效像素点，但本发明实施例不限于此。
应理解，上面例子中假设该触摸数据和基准数据分别包括该第一区域中每个像素点的数值，可选地，该触摸数据和基准数据也可以仅包括该第一区域中的一部分像素点的数值，相应的判断误触的方法与上述实施例类似，为了简洁，这里不再赘述。
通过上述流程，该协处理器140可以根据对该第一区域的像素点的数据的处理，判断误触事件。可选地，如果该第一区域为该指纹检测区域的一部分，并且该指纹检测区域还包括第二区域，例如，该指纹检测区域由该第一区域和该第二区域组成。作为一个例子，该协处理器140可以对该第二区域执行上述对第一区域的流程，以确定该第二区域中的有效触摸点在该第二区域的总像素点中所占的比例是否满足预设条件。可选地，如果该第一区域和第二区域中存在有效触摸点的比例满足预设条件的区域，则该协处理器140可以确定该触摸/按压事件为有效手指触摸/按压，反之，如果该第一区域和该第二区域中不存在有效触摸点的比例满足预设条件的区域，则该协处理器140可以确定该触摸/按压事件为误触。或者，只有在该第一区域和该第二区域中的每个区域中的有效触摸点的比例满足预设条件，该协处理器140才确定该触摸/按压事件为有效手指触摸/按压，反之，如果该第一区域和该第二区域中存在有效触摸点的比例不满足预设条件的区域，则该协处理器140可以确定该触摸/按压事件为误触，但本发明实施例不限于此。
可选地，如果该协处理器140确定该触摸/按压事件不为误触事件，即该触摸/按压事件为有效手指触摸/按压，则该协处理器140可以唤醒该主处理器130，以使得该主处理器130进行指纹识别。例如，该协处理器140可以通过写特定的寄存器来唤醒主处理器130，但本发明实施例不限于此。
可选地，该协处理器140还可以进一步将该触摸数据作为指纹采集数据存储至该电子设备100的存储器中，相应地，该主处理器130可以从该存储器中获取该指纹采集数据，并根据该指纹采集数据，进行指纹识别，但本发明实施例不限于此。
在本发明实施例中，该电子设备100可以具体为终端设备，例如手机、平板电脑等，本发明实施例对此不做限定。

在S230中，可以根据该触摸数据，确定该触摸事件为误触还是有效手指触摸或按压。可选地，如果确定该触摸事件为有效手指触摸或按压，则可以唤醒主处理器。例如，通过写特定的寄存器，来唤醒主处理器，但本发明实施例不限于此。可选地，如果确定该触摸事件为误触，则可以继续检测触摸屏上的触摸事件。这样，可以避免主处理器由于误触而被频繁唤醒，从而节约设备功耗，提高续航能力，进而提高用户体验。
可选地，如果确定该触摸事件为有效手指触摸或有效手指按压，还可以将该触摸数据作为指纹采集数据并存储至存储器中，以使得主处理器可以从该存储器获取该指纹采集数据并根据该指纹采集数据进行指纹识别，但本发明实施例不限于此。
可选地，S230，根据该触摸数据，确定该触摸事件是否为误触，包括：

可选地，如果该第一区域中的有效触摸点的数量与该第一区域中的总像素点的数量的比值不满足预设条件，则可以确定该触摸事件为误触。可选地，如果该第一区域中的有效触摸点的数量与该第一区域中的总像素点的数量的比值不满足预设条件，则可以确定该触摸事件为误触。
作为另一个可选实施例，如果该触摸数据和基准数据还包括至少一个第二区域中每个第二区域的多个像素点的数据，则还可以确定该至少一个第二区域中每个第二区域的有效触摸点所占的比例是否满足预设条件。此时，作为一个例子，如果在该至少一个第二区域和该第一区域中存在有效触摸点所占比例满足预设条件的区域，则可以确定该触摸事件为有效手指触摸/按压。相应地，如果该至少一个第二区域和该第一区域中的所有区域的有效触摸点所占比例均不满足预设条件，则可以确定该触摸事件为误触。
此时，可选地，如果该第一区域中的有效触摸点的数量与该第一区域中的总像素点的数量的比值不满足预设条件，则可以确定该触摸事件为误触，可以包括：
如果该第一区域中的有效触摸点所占的比例不满足预设条件，则可以确定该至少一个第二区域中的有效触摸点所占的比例是否满足预设条件；
如果该至少一个第二区域中不存在有效触摸点所占的比例满足预设条件的第二区域，则可以确定该触摸事件为误触。
作为另一个例子，如果在该至少一个第二区域和该第一区域中所有区域的有效触摸点所占比例均满足预设条件，则可以确定该触摸事件为有效手指触摸/按压。相应地，如果该至少一个第二区域和该第一区域中存在有效触摸点所占比例不满足预设条件的区域，则可以确定该触摸事件为误触。
此时，可选地，如果该第一区域中的有效触摸点的数量与该第一区域中的总像素点的数量的比值不满足预设条件，则可以确定该触摸事件为误触， 可以包括：
如果该第一区域中的有效触摸点所占的比例不满足预设条件，则可以确定该至少一个第二区域中的有效触摸点所占的比例是否满足预设条件；

可选地，在获取该指纹检测区域的与该触摸事件对应的触摸数据之前，该方法还包括：
通过指纹模组获取该指纹检测区域的基准数据；
将获取到的该基准数据存储至存储器。
此时，在判断误触的流程中，可以获取该存储器存储的该指纹检测区域的该基准数据。
可选地，在获取该触摸屏的指纹检测区域的与该触摸事件对应的触摸数据之前，该方法还包括：
确定该触摸事件所对应的触摸位置是否位于该指纹检测区域中；
若确定该触摸事件所对应的触摸位置位于该指纹检测区域中，指示指纹模组采集到该指纹检测区域的触摸数据。
下面将结合具体例子，详细描述本发明实施例提供的无线通信方法。在以下例子中，假设指纹模组采集到的数据包括指纹检测区域内的X*Y个像素点中每个像素点的数值。
如果MCU检测到指纹检测区域中的触摸事件，通过SPI接口读取FP采集到的触摸数据{R(1,1),…,R(1,Y),…,R(x,1),…,R(x,Y),…,R(X,1),…,R(X,Y)}。
MCU从与AP共享的DRAM存储区中获取基准数据{B(1,1),…,B(1,Y),…,B(x,1),…,B(x,Y),…,B(X,1),…,B(X,Y)}。
MCU将指纹检测区域分为以下四个区域{(1,1),…,(X/2,Y/2)}、{(X/2+1,1),…,(X,Y/2)}、{(1,Y/2+1),…,(X/2,Y)}和{(X/2+1,Y/2+1),…,(X,Y)}，并计算每个区域的阈值TH1～TH4：
Figure PCTCN2017080792-appb-000004
Figure PCTCN2017080792-appb-000005
Figure PCTCN2017080792-appb-000006
Figure PCTCN2017080792-appb-000007
MCU对每个像素点的基准值和原始值的差的绝对值abs(B(x,y)-R(x,y))与该每个像素点所属区域的阈值做比较，若像素点的基准值和原始值的差的绝对值小于阈值，则认为该像素点是有效触摸点，否则为无效触摸点。
如果每个区域的有效触摸点的数量大于X*Y*0.3/4(第一阈值)且小于X*Y*0.7/4(第二阈值)，则认为检测到的触摸事件为有效手指触摸/按压，否则认为检测到的触摸事件为误触。
