Description

一种信号上报方法及装置 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种信号上报方法及装置。
背景技术
触摸屏又称为“触控屏”或“触控面板”，是一种可接收触头等输入讯号的感应式显示装置。如图1所示，触摸屏的工作面100中一般设置有阵列排布的M*N(M≥1，N≥1)个电容器件101，当用户触摸工作面上的某个位置时，在人体电场的作用下，用户手指和工作面100之间会形成一个耦合电容。此时，与用户手指对应的一个或多个电容器件101的电容信号会发生改变，那么，触摸屏将当前各电容信号上报给电子设备内的处理器后，处理器便可以根据不同位置处的电容信号确定出用户的具体手势等信息。
目前，电子设备对触摸响应的灵敏度要求越来越高，以包含32*18个电容器件的触摸屏为例，当数据传输频率为120Hz时，如果电子设备的触摸屏要实时传输触摸屏内各个电容器件的电容信号，则每秒共需上报120*32*18＝69120个电容信号。这对于数据传输时常用的集成电路总线(I2C)总线或串行通信接口(SCI)而言，电容信号的上报过程将占用很大的传输带宽，使电子设备的响应速度变慢，并且增加了电子设备的功耗。
发明内容
本发明实施例提供一种信号上报方法及装置，可降低电容信号上报过程中占用的传输带宽，提高电子设备的响应速度并降低电子设备的功耗。
为达到上述目的，本发明实施例采用如下技术方案：
第一方面，本发明实施例提供一种信号上报方法，包括：电子设备获取用户在触摸屏(该触摸屏设置有阵列排布的M*N个的电容器件，M＞0，N＞0)上触发的触摸事件；响应于该触摸事件，电子设备得到K(0＜K＜M*N)个电容器件(该K个电容器件为该M*N个电容器件中的任意K个)中每个电容器件生成的电容信号；电子设备上报目标数据，该目标数据包括该K个电容器件中每个电容器件生成的电容信号。
可以看出，在电子设备上报电容信号时，无需向现有技术中那样将所有的M*N个电容信号上报给处理器，而是有选择性的将其中的K个电容信号上报给电子设备的处理器。这样，可以降低电子设备上报电容信号时的数据量，从而降低电容信号上报过程中占用的传输带宽，提高了电子设备的响应速度并降低电子设备的功耗。
在一种可能的设计方法中，该目标数据还包括位置信息，该位置信息用于指示上述K个电容器件与M*N个的电容器件之间的位置关系。
在一种可能的设计方法中，电子设备得到K个电容器件中每个电容器件生成的电容信号，包括：电子设备确定与该触摸事件中触摸点位置对应的目 标电容器件；电子设备根据该目标电容器件所在的位置，确定包含该目标电容器件的K个电容器件；电子设备获取这K个电容器件中每个电容器件生成的电容信号。
也就是说，电子设备上报时只需上报与触摸位置对应的K个电容信号以及位置信息，从而降低了电容信号的传输量，进而，电子设备对该触摸事件的响应速度将会提高，同时可以增加电子设备的待机时间。
在一种可能的设计方法中，电子设备根据目标电容器件所在的位置，确定包含目标电容器件的K个电容器件，包括：当该目标电容器件位于第一区域时，电子设备将以该目标电容器件为中心的X1*Y1个电容器件作为该K个电容器，X1＝Y1，该第一区域为位于该触摸屏中心的区域；当该目标电容器件位于第二区域时，电子设备将包含该目标电容器件的X2*Y2个电容器件作为该K个电容器，X2＜Y2，该第二区域为位于该触摸屏第一侧边的区域；当该目标电容器件位于第三区域时，电子设备将包含该目标电容器件的X3*Y3个电容器件作为该K个电容器，X3＞Y3，该第三区域为位于该触摸屏第二侧边的区域，该第二侧边的长度大于该第一侧边的长度；当该目标电容器件位于第四区域时，电子设备将目标区域内的所有电容器件作为该K个电容器，该第四区域为位于该触摸屏四个顶点的区域，该目标区域为该第四区域中与该触摸事件中触摸点位置对应的顶点的区域。这样，针对触摸屏上的不同区域，可以选择上述K个电容器的策略也可以不同，从而实现有针对性的电容信号上报过程。
在一种可能的设计方法中，在电子设备上报目标数据之后，还包括：电子设备将电容矩阵中每一个元素的取值设置为预设的初始值，该电容矩阵包括M*N个元素；电子设备根据该位置信息，将上述K个电容器件中每个电容器件生成的电容信号添加至该电容矩阵中。
在一种可能的设计方法中，电子设备得到K个电容器件中每个电容器件生成的电容信号，包括：电子设备对上述M*N个电容器件产生的M*N个电容信号执行下采样，得到下采样后K个电容器件中每个电容器件产生的电容信号，该下采样的采样率为小于1的正数。这样，可以降低电容信号的数据传输量。
在一种可能的设计方法中，电子设备对该M*N个电容器件产生的M*N个电容信号执行下采样，包括：当电子设备运行第一应用时，电子设备按照第一采样率对该M*N个电容器件产生的M*N个电容信号执行下采样；当电子设备运行第二应用时，电子设备按照第二采样率对该M*N个电容器件产生的M*N个电容信号执行下采样，该第二采样率大于该第一采样率。
这样，当电子设备运行第一应用时，电子设备可以自动将下采样的采样率调整为上述第一采样率，由于第一采样率的值较低，因此，电子设备上报电容信号的数据量将进一步减少，电子设备的耗电量也将下降；而当电子设备运行第二应用时，电子设备可以自动将下采样的采样率调整为上述第二采样率，由于第二采样率的值较高，因此，可以保证电子设备及时准确的响应 用户触发的触摸事件。
在一种可能的设计方法中，在电子设备得到K个电容器件中每个电容器件生成的电容信号之后，还包括：电子设备按照预设的压缩率(压缩率为小于1的正数)压缩这K个电容器件中每个电容器件产生的电容信号，得到K个压缩后的电容信号；其中，上述目标数据包括压缩后这K个电容器件中每个电容器件生成的电容信号。这样，在上报电容信号时，可以将这K个电容信号进一步的压缩，从而进一步降低电子设备上报电容信号时的数据量，提高电子设备的响应速度。
第二方面，本发明实施例提供一种信号上报方法，包括：电子设备获取用户在触摸屏(该触摸屏设置有阵列排布的M*N个的电容器件，M＞0，N＞0)上触发的触摸事件；响应于该触摸事件，电子设备按照预设的压缩率压缩该M*N个电容器件中每个电容器件产生的电容信号，得到M*N个压缩后的电容信号，该预设压缩率为小于1的正数；电子设备上报该M*N个压缩后的电容信号。那么，上述电容信号的上报方法不仅可以降低电子设备上报电容信号时的数据量，还无需处理器执行还原上述M*N个电容器件生成的M*N个电容信号的过程，从而可以进一步提高电子设备的响应速度并降低电子设备的功耗。
在一种可能的设计方法中，该压缩率为压缩后一个电容信号所需的精度与压缩前一个电容信号所需的精度的比值；其中，电子设备按照预设的压缩率压缩该M*N个电容器件中每个电容器件产生的电容信号，得到M*N个压缩后的电容信号，包括：对于该M*N个电容器件中的每个电容器件：电子设备将该电容器件产生的电容信号与该压缩率的乘积，作为该电容器件压缩后的电容信号。

这样，当电子设备运行第一应用时，电子设备可以自动将压缩率调整为上述第一压缩率，由于第一压缩率的值较低，因此，电子设备上报电容信号的数据量将进一步减少，电子设备的耗电量也将下降；而当电子设备运行第二应用时，电子设备可以自动将压缩率调整为上述第二采样率，由于第二压缩率的值较高，因此，可以保证电子设备及时准确的响应用户触发的触摸事件。

具体实施方式
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本发明实施例提供一种信号上报方法，可应用于任意设置有触摸屏的电子设备，例如，手机、可穿戴设备、AR(增强现实)\VR(虚拟现实)设备、平板电脑、笔记本电脑、UMPC(超级移动个人计算机)、上网本、PDA(个人数字助理)等，本发明实施例对此不作任何限制。
具体的，电子设备的触摸屏一般设置有至少一个可接收用户输入的工作面，在靠近工作面的一侧可设置阵列排布的M*N个的电容器件。该电容器件可以是任意具有电容功能的传感器。
例如，这M*N个的电容器件可以是由ITO(氧化铟锡)制作而成的横向与纵向排布的M*N个电极阵列。当手指触摸触摸屏的工作面时，手指与工作面之间形成一个耦合电容，由于工作面上通有高频信号，因此，手指触摸时在触摸位置吸走一个小电流，从而改变了触摸位置处至少一个电容器件的电容信号。那么，触摸屏可以将触摸屏内的电容信号上报给电子设备的处理器，处理器可以根据该电容信号确定出具体的触摸位置、操作手的大小以及指关节形状等信息。
在本发明实施例中，当电子设备获取到用户在触摸屏上触发的触摸事件后，可得到触摸屏上所有电容器件(即上述M*N个电容器件)的生成的电容信号，例如，每个电容器件响应于该触摸事件生成的电容值。此时，电子设备从上述M*N个电容器件生成的M*N个电容信号中确定K(0＜K＜M*N)个电容信号，并将这K个电容信号上报给电子设备的处理器，由处理器根据这K个电容信号还原出上述M*N个电容器件生成的M*N个电容信号。
可以看出，在电子设备上报电容信号时，无需向现有技术中那样将所有的M*N个电容信号上报给处理器，而是有选择性的将其中的K个电容信号上报给电子设备的处理器，例如，包含与触摸位置对应的K个电容器件生成的K个电容信号。这样，可以降低电子设备上报电容信号时的数据量，从而降低电容信号上报过程中占用的传输带宽，提高了电子设备的响应速度并可降低电子设备的功耗。
又或者，在电子设备上报电容信号时，电子设备还可以将上述M*N个电容信号中每个电容信号进行压缩，例如，对每个电容信号中的电容值按照一个预设的压缩率(压缩率为小于1的正数)压缩，这样，电子设备可以将压缩后的M*N个电容信号上报给电子设备的处理器，此时，处理器可以直接根据压缩后M*N个电容信号确定出与上述触摸事件对应的触摸位置、操作手的大小或者指关节形状等信息。
可以看出，这种电容信号的上报方法不仅可以降低电子设备上报电容信号时的数据量，还无需处理器执行还原上述M*N个电容器件生成的M*N个电容信号的过程，从而可以进一步提高电子设备的响应速度并降低电子设备的功耗。
另外，由于本发明实施例中可以将触摸事件中实时生成的电容信号上报给电子设备的处理器，而不是单一的上报触摸事件中触摸位置处的位置坐标，因此，电子设备的处理器可以根据上报的实时电容信号更加准确的判断该触摸事件中用户的触摸趋势。
例如，当触摸事件中用户用手指重击屏幕时，由于用户手指在触摸屏上接触面积的改变，可能会导致手指在触摸屏上的位移变大。那么，电子设备如果仅凭触摸位置的位置坐标很可能将用户的点击操作确定为滑动操作。而利用本发明实施例提供的信号上报方法，可以实时获取到单击操作产生的电容信号，那么，通过对电容信号形成的手指形状进行判断，可以识别出当前较大的位移变化，是否是因为手指在触摸屏上的接触面积发生变化而导致的，如果是，则说明该触摸事件为单击操作，进而执行与单击操作对应的操作指令，从而避免将用户的点击操作错误的判断为滑动操作。
示例性的，上述电容信号可以以数据包的形式进行上报，那么，使用本发明实施例提供的信号上报方法，将显著降低上报电容信号时数据包的发送量和/或每个数据包的大小。
下面将结合图2对电子设备的各个构成部件进行具体的介绍：
RF电路21可用于收发信息或通话过程中，信号的接收和发送，特别地，将无线接入设备的下行信息接收后，给处理器27处理；另外，将上行的数据发送给无线接入设备。通常，RF电路包括但不限于天线、至少一个放大器、收发信机、耦合器、低噪声放大器(LNA)、双工器等。此外，RF电路21还可以通过无线通信与网络和其他设备通信。
存储器22可用于存储软件程序以及模块，处理器27通过运行存储在存储器22的软件程序以及模块，从而执行电子设备的各种功能应用以及数据处理。
输入单元23可用于接收输入的数字或字符信息，以及产生与电子设备的用户设置以及功能控制有关的键信号输入。具体地，输入单元23可包括触摸屏341以及其他输入设备342。
显示单元24可用于显示由用户输入的信息或提供给用户的信息以及电子设备的各种菜单。显示单元24可包括显示面板351，可选的，可以采用液 晶显示器(LCD)、有机发光二极管(OLED)等形式来配置显示面板351。
摄像头25，也可以作为一种输入设备，具体用于将采集到的模拟视频或图像信号转换成数字信号，进而将其储存在存储器22中。具体的，摄像头25可以包括前置摄像头、后置摄像头、内置摄像头以及外置摄像头等，本发明实施例对此不作任何限制。
电子设备还可以包括重力传感器以及其它传感器，比如，光传感器、陀螺仪、气压计、湿度计、温度计、红外线传感器等，在此不再赘述。
音频电路26、扬声器371、麦克风372可提供用户与电子设备之间的音频接口。音频电路26可将接收到的音频数据转换后的电信号，传输到扬声器371，由扬声器371转换为声音信号输出；另一方面，麦克风372将收集的声音信号转换为电信号，由音频电路26接收后转换为音频数据，再将音频数据输出至RF电路21以发送给比如另一电子设备，或者将音频数据输出至存储器22以便进一步处理。
处理器27是电子设备的控制中心，利用各种接口和线路连接整个电子设备的各个部分，通过运行或执行存储在存储器22内的软件程序和/或模块，以及调用存储在存储器22内的数据，执行电子设备的各种功能和处理数据，从而对电子设备进行整体监控。可选的，处理器27可包括一个或多个处理单元。
尽管未示出，上述电子设备还可以包括电源、Wi-Fi(无线保真)模块、蓝牙模块等，在此不再赘述。
以下，将结合具体实施例详细阐述本发明实施例提供的一种信号上报方法，如图3所示，该方法包括：
101、电子设备获取用户在触摸屏上触发的触摸事件，该触摸屏设置有阵列排布的M*N个的电容器件，M＞0，N＞0。
具体的，电子设备可以以一定的频率实时扫描触摸屏上的电容信号，当检测到一个或多个电容信号发生改变时，电子设备可以确定用户在触摸屏的工作面上触发了触摸事件，例如，单击操作或滑动操作等。
可选的，当电子设备获取到在触摸屏上触发的触摸事件后，可以先根据触摸位置、触摸时间、触摸位置处的电容信号等参数判断当前的触摸事件是否为有效触摸事件。例如，当检测到M*N个的电容器件中，某个电容器件产生的电容信号大于一个阈值，或者，相邻的多个(例如4个)电容器件产生的电容信号之和大于一个阈值时，电子设备可确定在该触摸屏上出现一个有效触摸事件。
当确定上述触摸事件为有效触摸事件时，可继续执行下述步骤102-106，这样，可以避免电子设备上报没有意义的电容信号，从而降低上报电容信号过程中的数据传输量。
另外，上述触摸事件也可以为悬浮触控(Floating Touch)事件，其中，悬浮触控是指当用户的手指在屏幕上悬停时，触摸屏上的电容器件便可以在人体电场的作用下生成电容信号。这样，电子设备可以检测到在屏幕上方一 定距离处的手指产生的电容信号，进而根据该电容信号进行手势预判等处理。
102、响应于上述触摸事件，电子设备确定与该触摸事件中触摸点位置对应的目标电容器件，该目标电容器件为上述M*N个的电容器件中的任一个。
当用户在触摸屏上触发一个触摸事件时，电子设备可以将上述M*N个的电容器件中电容信号改变值较大的一个或多个电容器件作为目标电容器件，例如，将上述有效触摸事件中检测到的电容信号取值最大的电容器件作为目标电容器件。
又或者，如图4所示，还可以沿用现有技术中确定触摸事件中触摸点位置坐标的方法确定上述目标电容器件，此时，触摸点位置坐标可以是在显示屏中的一个像素点的坐标，例如，图4中的Q(x，y)。
那么，假设该显示屏包含W*H个像素点，该显示屏包含M*N个的电容器件，则电子设备可以将该Q点的坐标Q(x，y)映射至M*N个的电容器件中，得到Q点在M*N个的电容器件中的位置为Q’(x’，y’)，其中，x’＝M*X/W,y’＝N*Y/H。
这样，与该触摸点位置对应的目标电容器件即为Q’(x’，y’)处的电容器件。
103、电子设备获取包含上述目标电容器件的K个电容器件中每个电容器件生成的电容信号，0＜K＜M*N。
在步骤103中，电子设备可以预先设置N1*N2个电容器件组成的区域，这样，当确定上述目标电容器件后，可以以上述目标电容器件为中心确定N1*N2个电容器件作为上述K个电容器件(N1*N2＝K)。
其中，显示屏内的每个电容器件响应于上述触摸事件都会生成一个电容信号，例如，该电容信号具体可以为电容值或电容值的变化量。那么，电子设备可以进一步地获取到上述K个电容器件中每个电容器件生成的电容信号，而其他位置处电容器件生成的电容信号一般为近似0的数值。
示例性的，如图5所示，当触摸事件中的触摸点位置只有一个时，电子设备可以将以目标电容器件为中心的3*3个电容器件作为上述K个电容器件，并获取这3*3个电容器件中每个电容器件生成的电容信号。
又或者，如图6所示，当触摸事件中的触摸点位置为多个(例如两个)时，电子设备可以将以每个触摸点位置对应的目标电容器件为中心的3*3个电容器件，作为上述K个电容器件，并获取这K个电容器件中每个电容器件生成的电容信号。
当然，上述K个电容器件所构成的区域还可以为长方形、圆形等任意形状，本发明实施例对此不作任何限制。
进一步地，电子设备可以预先将触摸屏幕划分成多个不同的区域，这样，对于不同的区域，电子设备可以根据目标电容器件的具体位置，采用不同的方法确定包含上述目标电容器件的K个电容器件。
示例性的，如图7所示，电子设备预先将触摸屏幕划分成第一区域、第二区域、第三区域以及第四区域。其中，第一区域是指位于触摸屏中心的区 域，第二区域是指位于触摸屏第一侧边(图7中为上下两侧边)的区域，第三区域是指位于触摸屏第二侧边(图7中为左右两侧边)的区域，第二侧边的长度大于第一侧边的长度，第四区域是指位于触摸屏四个顶点的四个区域。
那么，当电子设备确定上述目标电容器件位于第一区域时，如图8中的(a)所示，可以将以该目标电容器件为中心的X1*Y1(X1＝Y1)个电容器件作为上述K个电容器，即此时选择的K个电容器件组成一个正方形的区域。这样，在触摸屏的中心区域可以最大限度的获取到上述触摸事件触发的完整的电容信号。
当电子设备确定上述目标电容器件位于第二区域时，如图8中的(b)所示，电子设备可以将包含该目标电容器件的X2*Y2(X2＜Y2)个电容器件作为上述K个电容器，即此时选择的K个电容器件组成一个在x轴方向边长较长的长方形。这样，用户在第二区域触发触摸操作时，手指可能会有一部分超出触摸屏的上下边界，那么，电子设备可以尽可能的采集x轴方向上生成的电容信号，以提高后续识别该触摸操作的准确率。此时，上述X2*Y2个电容器件的中心不一定是上述目标电容器件。
相应的，当电子设备确定上述目标电容器件位于第三区域时，如图8中的(c)所示，电子设备可以将包含上述目标电容器件的X3*Y3(X3＞Y3)个电容器件作为上述K个电容器，即此时选择的K个电容器件组成一个在y轴方向边长较长的长方形。这样，用户在第三区域触发触摸操作时，手指可能会有一部分超出触摸屏的左右边界，那么，电子设备可以尽可能的采集y轴方向上生成的电容信号，以提高后续识别该触摸操作的准确率。此时，上述X3*Y3个电容器件的中心也不一定是上述目标电容器件。
而当电子设备确定上述目标电容器件位于第四区域时，例如图8中的(d)所示，假设目标电容器件位于触摸屏左下角的区域(即目标区域，目标区域为第四区域中与触摸点位置对应的顶点所在的区域)，此时，由于该目标区域通常面积较小，因此，电子设备可以将目标区域内的所有电容器件作为上述K个电容器，以提高后续识别该触摸操作的准确率。
另外，电子设备还可以确定出上述K个电容器件的位置信息，即这K个电容器件与上述M*N个的电容器件之间的相对位置关系。如图9所示，上述位置信息具体可以包括这K个电容器件中某个顶点的坐标(例如图9中右上角的电容器件的坐标P(x，y))，以及这K个电容器为一个3*3的矩阵。
104、电子设备上报目标数据，该目标数据包括上述K个电容器件中每个电容器件生成的电容信号和位置信息，该位置信息用于指示该K个电容器件与M*N个的电容器件之间的位置关系。
在步骤104中，电子设备可以将上述K个电容器件中每个电容器件生成的电容信号和位置信息作为目标数据上报给电子设备的处理器，以便于处理器根据该目标数据还原出整个触摸屏上N*M个电容器件的电容信号。
示例性的，如图9所示，电子设备上报的目标数据中具体包括图9中3*3个电容器件中每个电容器件生成的电容值和位置信息，该位置信息包括上述K 个电容器件为3*3个电容器件，以及这3*3个电容器件中右上角的电容器件的坐标P(x，y)。
这样，电子设备上报时只需上报K个电容信号以及位置信息，从而降低了电容信号的传输量，进而，电子设备对该触摸事件的响应速度将会提高，同时可以增加电子设备的待机时间。
105、电子设备设置电容矩阵中每一个元素为0，该电容矩阵包括M*N个元素。
106、电子设备根据上述位置信息，在电容矩阵中添加上述K个电容器件中每个电容器件生成的电容信号。
使用上述电容信号的设备，例如电子设备的处理器，可以先初始化一个大小为M*N的电容矩阵，其中，该电容矩阵中每一个元素的取值均为一个预设的初始值，例如，电容矩阵中每一个元素为等于或近似0的数值。
进而，在接收到上述目标数据后，电子设备根据上述位置信息，可以将电容矩阵中相应位置的元素的取值替换为接收到的相应电容信号。仍如图9所示，触摸屏上设置有11*7的电容器件，那么，电子设备根据图9中所示的目标数据可以确定相应的电容矩阵为：
Figure PCTCN2017081235-appb-000001
这样，电子设备便可以将M*N个电容器件分别生成的电容信号完整的还原出来，进而可根根据还原出的M*N个电容信号完成与步骤101中触摸事件对应的操作，例如手势识别等，本发明实施例对此不作任何限制。
当然，如果电容矩阵中每一个元素的初始值不是0时，电子设备可在还原上述电容矩阵时，直接将电容矩阵中相应位置处元素的初始值与接收到的相应电容信号相加，得到还原后该位置处的电容信号，此时，还原出的电容矩阵仍可表示出这M*N个电容信号之间的相对大小关系，从而使得电子设备可根根据还原出的M*N个电容信号完成与步骤101中触摸事件对应的操作。进一步地，如果上述触摸事件为悬浮触控事件，那么，在传输电容信号的过程中由于传输带宽的占用率降低，从而可以更加快速的将实时生成的电容信号发送给处理器，使得处理器能够更准确的进行手势预判或误触预识别等操作，从而提高悬浮触控的准确度。
本发明实施例提供一种信号上报方法，如图10所示，该方法包括：
201、电子设备获取用户在触摸屏上触发的触摸事件，该触摸屏设置有阵列排布的M*N个的电容器件，M＞0，N＞0。
202、响应于该触摸事件，电子设备对上述M*N个电容器件产生的M*N个电容信号执行下采样，得到K个电容器件中每个电容器件产生的电容信号。
其中，下采样的采样率具体可以为大于0且小于1的任意值。
具体的，当用户在触摸屏上触发一个触摸事件后，显示屏内的每个电容器件响应于上述触摸事件都会生成一个电容信号，那么，触摸屏内的M*N个电容器件共产生M*N个电容信号。其中，上述触摸事件也可以为悬浮触控事件，本发明实施例对此不作任何限制。
在步骤202中，电子设备可以对这M*N个电容信号的信号个数进行下采样，例如，如图11所示，以1/2的下采样采样率对上述M*N个电容信号下采样，得到K(K＝M*N/2)个电容信号。也就是说，下采样采样率为K/(M*N)。其中，黑色位置指示采集到的电容器件生成的电容信号，白色位置指示没有采集到的电容器件生成的电容信号。这样，可以将电容信号的数据传输量压缩为原来的50％。
当然，还可以以其他的采样率对上述M*N个电容信号进行下采样。如图12所示，当下采样采样率为2/3时，图12中的(a)、(b)、(c)分别提供了三种可能的下采样的方式，本发明实施例对此不作任何限制。其中，黑色位置指示采集到的电容器件生成的电容信号，白色位置指示没有采集到的电容器件生成的电容信号。
进一步地，用户也可以在电子设备上对上述下采样的采样率进行设置，又或者，电子设备也可以根据当前电子设备运行的应用调整上述下采样的采样率，本发明实施例对此不作任何限制。
示例性的，当电子设备正在运行对触摸精度要求不高的第一应用(例如，视频播放应用)时，电子设备可以按照较低的第一采样率对上述M*N个电容信号执行下采样；而当电子设备运行对触摸精度要求较高的第二应用(例如，游戏应用)时，电子设备可以按照较高的第二采样率(第二采样率大于第一采样率)对上述M*N个电容信号执行下采样。
这样，当电子设备运行第一应用时，电子设备可以自动将下采样的采样率调整为上述第一采样率，由于第一采样率的值较低，因此，电子设备上报电容信号的数据量将进一步减少，电子设备的耗电量也将下降；而当电子设备运行第二应用时，电子设备可以自动将下采样的采样率调整为上述第二采样率，由于第二采样率的值较高，因此，可以保证电子设备及时准确的响应用户触发的触摸事件。
203、电子设备上报上述K个电容器件中每个电容器件生成的电容信号。
204、电子设备根据上述K个电容器件中每个电容器件生成的电容信号，还原出上述M*N个电容信号。
具体的，在步骤204中，电子设备得到K个电容器件中每个电容器件生成的电容信号，即K个电容信号后，未被采集到的电容信号可以通过其周围 采集到的电容信号估算出来。
示例性的，如图13所示，以估算A处的电容信号为例，电容器件A周围采集到了A2、A4、A5以及A7四个电容器件的电容信号。那么，电子设备可以将A2、A4、A5以及A7这四个电容器件的电容信号的平均值(或加权平均值)作为电容器件A的电容信号，例如，A＝(A2+A4+A5+A7)/4。
又或者，如图13所示，仍以估算A处的电容信号为例，在估算A处的电容信号时，A1、A3、A6以及A8中的一个多个电容信号可能已经被估算出来，那么，电子设备可以将A2、A4、A5、A7以及已经估算出的A1、A3、A6、A8处的电容信号的平均值(或加权平均值)作为电容器件A的电容信号，例如，A＝(A2+A4+A5+A7+A1+A3+A6+A8)/8。
这样，电子设备便可以将M*N个电容器件分别生成的电容信号完整的还原出来，进而可根根据还原出的M*N个电容信号完成与步骤201中触摸事件对应的操作，例如手势识别等，本发明实施例对此不作任何限制。
本发明实施例提供一种信号上报方法，如图14所示，该方法包括：
301、电子设备获取用户在触摸屏上触发的触摸事件，该触摸屏设置有阵列排布的M*N个的电容器件，M＞0，N＞0。
302、响应于该触摸事件，电子设备按照预设的压缩率压缩上述M*N个电容器件中每个电容器件产生的电容信号，得到M*N个压缩后的电容信号。
其中，上述压缩率具体可以为大于0且小于1的任意值。
具体的，当用户在触摸屏上触发一个触摸事件后，显示屏内的每个电容器件响应于上述触摸事件都会生成一个电容信号，那么，触摸屏内的M*N个电容器件共产生M*N个电容信号。其中，上述触摸事件也可以为悬浮触控事件，本发明实施例对此不作任何限制。
在步骤302中，电子设备可以对这M*N个电容信号中的每个电容信号进行压缩。例如，如图15所示，电子设备响应于上述触摸事件，生成了M*N个电容信号(其中未标数字的位置可默认电容信号为0)，电子设备可将上述每一个电容信号压缩0.1倍，得到M*N个压缩后的电容信号。这样，电子设备只需将这M*N个压缩后的电容信号上报给处理器即可，压缩后的传输量降低为压缩前传输量的10％。并且，这M*N个压缩后的电容信号已经反映了上述M*N个电容信号之间的大小关系，因此，电子设备无需对这M*N个压缩后的电容信号进行还原，即可根根据上述M*N个压缩后的电容信号完成与步骤301中触摸事件对应的操作。
进一步地，电子设备一般使用h(h＞1)个比特位表示一个电容信号。例如，电子设备可以使用16比特位表示0-65536(2^16＝65536)中的任一个电容信号。即压缩前一个电容信号的精度为65536。
在本发明实施例中，可以将上述h个比特位压缩为d(1＜d＜h)个比特位，以达到压缩电容信号的目的。例如，将16比特位压缩为8比特位，即压缩后的电容信号使用8比特位表示，即压缩后的电容信号为0-256(2^8＝256)中的任一个值。其中，压缩后一个电容信号的精度为256。
此时，上述压缩率具体可以为压缩后一个电容信号所需的精度与压缩前一个电容信号所需的精度的比值，即压缩率为2^d/2^h。
示例性的，如图16所示，压缩前某个电容器件生成的电容信号取值为16384，该电容信号使用16个比特位来表示。那么，在步骤302中，如果压缩后表示一个电容信号的比特位个数为8，那么，假设压缩后该电容信号取值为e，e应满足关系：e/256＝16384/65536，则e＝(16384/65536)*256＝64。也就是说，压缩后该电容信号使用8比特位表示为64。那么，电子设备只需使用8比特位将该压缩后的电容信号64上报给处理器，无需使用16比特位上报压缩前的电容信号16384，从而降低了上报电容信号时的数据传输量。
进一步地，与步骤202类似的，用户也可以在电子设备上对上述压缩率进行设置，又或者，电子设备也可以根据当前电子设备运行的应用调整上述压缩率，本发明实施例对此不作任何限制。
示例性的，当电子设备正在运行对触摸精度要求不高的第一应用(例如，视频播放应用)时，电子设备可以按照较低的第一压缩率对上述M*N个电容信号执行下采样；而当电子设备运行对触摸精度要求较高的第二应用(例如，游戏应用)时，电子设备可以按照较高的压缩率(第二采样率大于第一采样率)对上述M*N个电容信号执行下采样。
这样，当电子设备运行第一应用时，电子设备可以自动将压缩率调整为上述第一压缩率，由于第一压缩率的值较低，因此，电子设备上报电容信号的数据量将进一步减少，电子设备的耗电量也将下降；而当电子设备运行第二应用时，电子设备可以自动将压缩率调整为上述第二采样率，由于第二压缩率的值较高，因此，可以保证电子设备及时准确的响应用户触发的触摸事件。
303、电子设备上报上述M*N个压缩后的电容信号。
304、(可选的)电子设备根据上述M*N个压缩后的电容信号，还原出M*N个压缩前的电容信号。
可选的，仍以上述将电容信号16384压缩为64举例，压缩前该电容信号取值e’满足关系：64/256＝e’/65536，那么，电子设备收到该压缩后的电容信号为64后，可根据上述关系计算出e’＝(64/256)*65536＝16384。
那么，对于每一个压缩后的电容信号，均可以按照上述关系还原出压缩前该电容信号的取值，最终得到M*N个压缩前的电容信号。
这样，电子设备便可以根根据还原出的M*N个电容信号完成与步骤201中触摸事件对应的操作，例如手势识别等，本发明实施例对此不作任何限制。
