请参照图2，是本发明实施例提供的图1所示的触控系统100的方框示意图。所述触控系统100可以包括：接收模块110、检测模块120及执行模块130。
所述接收模块110配置为接收所述触摸指纹传感器16的触控操作。
在本发明实施例中，接收模块110可以检测所述触摸指纹传感器16是否被触控操作的状态信息。所述接收模块110可以通过所述触摸指纹传感器16在被触控操作时与未被触控操作时电信号(比如，电压、电容值)的改变量来确定所述触摸指纹传感器16是否被触控操作，并在所述触摸指纹传感器16被触控时接收该触控操作。

在本发明实施例中，当用户的手指或皮肤触摸在触摸屏15表面时，由于人体电场的效应，用户与触摸屏15表面将形成一个耦合电容，进而引起触摸屏15上被触摸的矩阵点的电容值的变化。对此状态下的触摸屏15上各矩阵点进行采样，得到此状态下触摸屏15上各矩阵点对应的电容值，并将其作为各矩阵点的采样电容值。

在本发明实施例中，所述预设触摸信息阈值与有效触摸信息是相互对应的。当所述有效触摸信息为所有电容差值大于预设电容阈值的矩阵点的数量时，所述预设触摸信息阈值为预设的触摸矩阵点数目阈值；当所述有效触摸信息为所有电容差值大于预设电容阈值的矩阵点的所在区域在所述触摸屏15上所占的面积之和时，所述预设触摸信息阈值为预设的面积阈值。在本发明实施例中，所述预设触摸信息阈值可由用户或者移动终端10的生产厂家进行设定，可以用于反映移动终端10的触控等级。
在本发明实施例中，所述预设操作包括，但不限于控制触摸指纹传感器16进行指纹识别、通过触摸指纹传感器16对移动终端10进行解锁、控制触摸指纹传感器16进行在线支付(比如，Apple pay)、通过触摸指纹传感器16进行账户登录等。
可选地，在本发明实施例中，所述预设操作为控制触摸指纹传感器16进行指纹识别。

当所述有效触摸信息大于预设触摸信息阈值时，中止所述触摸指纹传感器16对所述触控操作的响应。防止因误触摸导致触摸指纹传感器16被误触发，从而导致移动终端10产生频繁的震动提醒或解锁次数过多导致的锁屏问题，影响移动终端10的续航能力和用户体验。
请再次参照图4，所述触控系统100还包括采集模块140。
