具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种终端的控制方法，图1是根据本发明实施例的终端的控制方法流程图，如图1所示，该流程包括如下步骤：
步骤S102，获取终端显示屏上用户与终端依次接触的第一图像和第二图像；
可选的，第一图像和第二图像可以但不限于为：接触面积、指纹信息，也可以是眼纹信息等用户直接或间接与终端之间接触的信息，在本实施中，以较为常用和采集方便的用户与显示屏的接触面积，以及可识别度较高的指纹信息进行举例说明，本实施例中的终端显示屏可以识别用户的指纹信息。可选的，根据用户依次在终端上操作产生的第一图像和第二图像，先获取第一图像，再获取第二图像。
步骤S104，在第二图像和第一图像匹配时，获取第一图像中的第一直线与第二图像中的第二直线之间的角度，并执行与角度对应的用于控制终端的操作。
可选的，对于该判断第二图像和第一图像是否匹配的方式，在本实施例中的第一图像和第二图像涉及：接触面积、指纹信息时，可以通过如下方式来实现，判断第一图像与第二图像中的接触面积之间的差值是否小于预设阈值，或该第一图像中的指纹信息与该第二图像中的指纹信息是否匹配；在本发明实施例中，可以预设阈值为2平方厘米，在获取到的图像中，如第一图像的接触面积为5平方厘米，在第二图像信息的接触面积与5平方厘米的差值小于2平方厘米时，如第二图像的接触面积为6平方厘米，差值为1平方厘米，确定第一图像和第二图像是匹配的，可选的，还可以根据终端显示屏的大小和用户与显示屏接触面积的大小来设置阈值。而在图像为指纹信息时，则直接根据第一图像信息和第二图像信息中的指纹信息进行匹配。
判断第一图像和第二图像的接触面积的差值小于阈值时，计算第二次图像中的接触面积到第一次图像中的接触面积，或计算第二次图像中的指纹信息到第一次图像中的指纹信息，此时，为了方便计算角度，接触面积或指纹信息可以处理为用户与终端接触的在显示屏上的一个点，然后根据该角度生成控制终端的机器指令，终端依据该机器指令执行操作。
通过本实施例，采用依次获取终端显示屏上用户与终端接触的第一图像和第二图像，其中，第一图像和第二图像包括：接触面积和/或指纹信息，然后判断第一图像与第二图像中的 接触面积之间的差值是否小于预设的阈值，或指纹信息是否匹配，在判断结果为是时，计算第二图像到第一图像的角度，并执行与角度对应的用于控制终端的操作，解决了相关技术中只能根据单指的点击或划线来实现终端操作的问题，实现了一种单手操作终端的方法，进而达到了利用手指旋转就能实现操作终端的效果。
在根据本实施例的可选实施方式中，控制终端的操作可以但不限于为：缩放显示屏显示的图像尺寸、缩放显示屏显示的页面尺寸、调节终端的音量大小、调节显示屏的亮度、解锁和锁住显示屏，可选的，可以根据终端具体的应用场景和终端系统的当前运行情况设置本次的操作，如在视屏播放界面，设置操作为调节终端的音量大小。
在本实施例的一个可选实施方式中，对于本实施例中涉及到的依次获取终端显示屏上用户与终端接触的第一图像和第二图像的方式，可以通过如下方式来实现：
S11，获取用户与显示屏接触的区域闭合形状边缘点的坐标，并根据坐标计算出区域闭合形状的面积，和/或获取区域闭合形状内的指纹信息；
在本实施例中，根据手指和显示屏接触的区域，获取该区域的闭合边缘点的坐标，将所有坐标围起来的面积作为接触面积，以此作为图像，或者直接将采集的指纹信息作为图像，可选的，也可以将接触面积和指纹信息整体作为图像。
S12，将区域闭合形状的面积和/或指纹信息确定为第一图像，以及将区域闭合形状的面积和/或指纹信息确定为第二图像。
在本实施例的另一个可选实施方式中，本实施例涉及到的计算第二图像到第一图像的角度的方式，可以通过如下方式来实现：
S21，获取包含第一图像的区域闭合形状的最小圆的第一圆心位置，以及包含第二图像的区域闭合形状的最小圆的第二圆心位置；
在本实施例中，图像中的接触面积，或者图像中的指纹信息，都是用户与显示屏接触的用户生物特征信息，接触部位都会形成一个类似圆的形状，取包括该类似圆的最小圆的圆心位置为圆心位置。
S22，将第二圆心位置和第一圆心位置与预设参照点分别连成第二直线和第一直线；
可选的，预设参考点可以为终端显示屏上四个角的坐标，或者终端显示屏的中心点，在用户的接触位置和预设参考点重合时，也可以选择其他的备选预设参考点。在本实施方式中，以终端显示屏的中心点为例进行说明。
S23，计算第二直线到第一直线之间的夹角，并将夹角作为角度。
在本实施例中，第二直线到第一直线之间的夹角可以为正量和负量，可以用来表示一对相关的操作，如用来调节终端的音量大小时，正量表示调大，负量表示调小，而调节的幅度则根据第二直线和第一直线之间形成夹角的绝对值决定，在本实施例中，上述夹角的范围为0到180度。
在本实施例的又一个可选实施方式中，本实施例中涉及到的依次获取终端显示屏上用户与终端接触的第一图像和第二图像的方式，可以通过如下方式来实现：
S31，获取第一图像，并记录第一图像的获取时间为第一时间；
S32，获取第一时间之后的指定图像，并判断第二时间和第一时间的时间差是否超过预设阈值，其中，第二时间为指定图像的获取时间；
在本实施例的可选实施方式中，指定图像为在第一时间之后的任意一个图像，如果获取的指定图像较多，可以根据时间优先级进行排序，将第一时间之后最先获取的一个图像作为指定图像。
S33，在判断结果为否时，确定指定图像为第二图像；或，在判断结果为是时，用指定图像更新第一图像。
可选的，在判断超过阈值后，可以将上述指定图像更新设置为第一图像，然后继续获取第二图像，也可以直接放弃指定图像，继续依次获取第一图像和第二图像。
为了防止获取第一图像和第二图像的时间过长，在两次获取图像的操作中间设置一个阈值，通过判断阈值来确定是否使用当前获取的图像，防止了终端执行相应操作时，图像丢失而等待时间过长的问题，也消除了因为用户误触手机而无端生成操作指令而无故操作终端的烦恼。
在本实施例的可选实施方式中，在第一图像与第二图像中不匹配时，用第二图像更新第一图像或删除第一图像和第二图像。在根据本实施例的具体应用过程中，用户可能因为操作不当或者其他原因，操作终端产生的第一图像和第二图像可能不匹配，此时，可以将最新获取的第二图像更新设置为第一图像，或者直接删除第一图像和第二图像，再获取其他的图像，继续进行匹配。
在本实施例的可选实施方式中，执行与角度对应的用于控制终端的操作包括：
S41，获取角度的旋转方向和角度值，其中，旋转方向包括：顺时针方向和逆时针方向；
S42，根据角度的旋转方向和/或角度的角度值执行用于控制终端的操作。
在本实施例的可选实施方式中，可以根据角度是顺时针方向和逆时针方向来指示执行一对相关的相反操作，如用来调节终端的音量大小时，顺时针表示调大，逆时针表示调小，而调节的幅度则根据角度的绝对值大小决定，在本实施例中，上述角度的范围在0和180度之间。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机， 服务器，或者网络设备等)执行本发明各个实施例的方法。
在本实施例中还提供了一种终端的控制装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

判断第一图像和第二图像的接触面积的差值小于阈值时，计算第二次图像中的接触面积到第一次图像中的接触面积，或计算第二次图像中的指纹信息到第一次图像中的指纹信息，此时，为了方便计算角度，接触面积或指纹信息可以处理为用户与终端接触的在显示屏上的一个点，然后根据该角度生成控制终端的机器指令，终端依据该机器指令执行操作。
