Description

屏幕显示的切换方法以及装置及存储介质
本申请要求在2018年04月19日提交中国专利局、申请号为201810356129.4的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端控制技术，例如涉及一种屏幕显示的切换方法、装置及存储介质。
背景技术
目前多屏终端产品是由两个及两个以上显示屏拼接而成的终端，通常情况来说，多屏终端会有多种不同的显示模式，包括多屏显示相同内容的模式，以及多屏分别显示不同内容的模式等。
用户在使用多屏终端的时候根据不同使用场景和使用爱好会切换到不同的屏幕显示模式进行显示输出，因此，多屏终端中显示模式切换的快速性和便捷性就成为至关重要的一点。目前存在的模式切换解决方案是在屏幕中设置有模式切换的按钮操作，用户通过点触屏幕实现不同显示模式的切换，例如在导航栏中加入切换按钮，用户首先第一步调出导航栏，第二步点击切换按钮，第三步根据不同显示模式选择切换。可以看出，完成一个显示模式切换需要在屏幕上操作三次，操作流程过于冗余，便捷性不高。

具体实施方式
下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
实施例一
如图1所示，该方法应用于具备至少两个显示屏幕的终端设备上；示例性的屏幕显示的切换方法包括：步骤101至步骤104。
在步骤101中，采集目标对象对触控区域执行滑动操作时产生的至少两个 触控位置信息。
在步骤102中，基于采集的至少两个触控位置信息，确定目标对象执行滑动操作的滑动方向。
在步骤103中，基于预设映射关系，确定至少两个显示屏幕所对应的目标显示模式；其中，预设映射关系包含至少一种滑动方向和至少一个显示模式之间的对应关系，显示模式用于表征至少两个显示屏幕中每一个显示屏幕的工作状态。
在步骤104中，控制终端设备的每一个显示屏幕由当前显示模式切换至目标显示模式。
实际应用中，步骤101至步骤104的执行主体可以为切换装置的处理器。
实际应用中，需要预先设置滑动方向与显示模式的映射关系，滑动方向可以包括第1滑动方向至第P滑动方向，显示模式可以包括第1显示模式至第Q显示模式，P和Q均取正整数。这里，映射关系中滑动方向与显示模式可以是一对一或者多对一的映射关系，可以利用设置的所有映射关系建立映射关系表，对映射关系进行统一管理。
示例性的，显示模式可以为单屏模式、镜像模式、全屏模式或分屏模式等任意适用的显示模式；其中，单屏模式用于指示至少两个显示屏幕中指定的一个显示屏幕作为显示输出；其余显示屏幕处于关闭状态；镜像模式用于指示至少两个显示屏幕中指定的两个显示屏幕作为显示输出，显示内容互为镜像；其余显示屏幕处于关闭状态；全屏模式用于指示至少两个显示屏幕中所有的显示屏幕作为显示输出，对显示内容进行协同显示；单屏模式用于指示至少两个显示屏幕中指定的多个显示屏幕作为显示输出，显示内容各自独立；其余显示屏幕处于关闭状态。
在一些实施例中，至少两个触控位置信息包括：第一位置的坐标和第二位置的坐标，坐标至少包括横坐标和纵坐标；相应地，所述步骤102可以包括：基于第一位置和第二位置的横坐标变化量，以及第一位置和第二位置的横坐标变化量，确定目标对象执行滑动操作的滑动方向。示例性的，第一位置可以为滑动操作的起始位置，第二位置可以为滑动操作的结束位置。
在一实施例中，所述步骤102例如可以包括：将横坐标变化量与零比较后，得到第一比较结果；将横坐标变化量和纵坐标变化量比较后，得到第二比较结果；基于第一比较结果和第二比较结果，确定目标对象执行滑动操作的滑动方 向。
示例性的，所述步骤102例如可以包括以下：
x>0且x>|y|，滑动方向为第一方向；
x>0且x<y；或者x<0且|x|<y，滑动方向为第二方向；
x<0且|x|>|y|，滑动方向为第三方向；
x>0且x<-y，或者x<0且|x|<-y，滑动方向为第四方向；
其中，x为第一位置和第二位置的横坐标变化量；y为第一位置和第二位置的纵坐标变化量。
在一些实施中，可以将第一位置和第二位置的坐标用二维坐标来表示，例如，第一位置坐标为(x1，y1)，第二位置坐标为(x2，y2)，横坐标变化量x＝x2-x1，纵坐标变化量y＝y2-y1。或者以第一位置为坐标原点，即x1＝0，y1＝0，横坐标变化量x＝x2，纵坐标变化量y＝y2。
以第一位置为坐标原点时，为了更清楚的解释坐标变化与滑动方向的关系，示例性的给出了如图2所示的滑动方向设置方式，xy坐标系中原点O为第一位置，坐标系中任意一个坐标为第二位置坐标(x2，y2)，根据(x2，y2)的数值判断滑动方向，当(x2，y2)位于区域(1)内，滑动方向为第一方向；当(x2，y2)位于区域(2)内，滑动方向为第二方向；当(x2，y2)位于区域(3)内，滑动方向为第三方向；当(x2，y2)位于区域(4)内，滑动方向为第四方向。应说明的是，实际应用中，所述滑动方向并不局限于图2所示的滑动方向的设置方式，所述滑动方向的设置方式可以依据用户的操作习惯以及触控区域的大小等参数进行相应的设置及更新等。
在一些实施例中，触控区域还包括指纹识别区域。至少两个触控位置信息为执行滑动操作时产生的至少两幅指纹图像的中心位置信息。可以理解的是，目标对象在对终端设备的指纹识别区域进行滑动操作时，由于滑动操作为一连串的连续操作，指纹传感器会在固定时间间隔连续采集指纹图像，通过分析指纹图像的位置变化规律，得到滑动操作的滑动方向。这里，用指纹图像的中心位置坐标来表示该幅指纹图像的位置信息，一幅指纹图像的中心位置坐标即为一个触控位置信息，其中，坐标可以包括横坐标和纵坐标；基于至少两幅指纹图像的中心位置坐标来确定目标对象的滑动方向。
实际应用中，所述步骤103例如可以包括：根据确定目标对象执行滑动操作的滑动方向，在映射关系中查找与该滑动方向对应的显示模式，即为目标显 示模式。
在一些实施例中，该方法还可以包括：
获取目标对象的待匹配指纹信息；
基于至少一个指纹样本信息对待匹配指纹信息进行匹配，得到匹配结果；
基于匹配结果，控制终端设备的每一个显示屏幕由当前显示模式切换至目标显示模式。
在一实施例中，基于匹配结果，控制终端设备的每一个显示屏幕由当前显示模式切换至目标显示模式，包括：匹配结果表示待匹配指纹信息与至少一个指纹样本信息中的一个指纹样本信息匹配时，控制终端设备的每一个显示屏幕由当前显示模式切换至目标显示模式。
也就是说，执行显示切换操作的前提是用户为授权用户，只有该用户的指纹信息被预先保存为指纹样本信息，该用户才能通过滑动操作控制显示模式切换；若为非授权用户则无法通过滑动操作控制显示模式切换，以此增加显示切换操作的安全性。
这里，具体的指纹识别技术是通过比较不同指纹的细节特征点来进行鉴别。指纹识别技术涉及图像处理，模式识别，计算机视觉，数学形态学，小波分析等众多学科。由于每个人的指纹不同，就是同一人的十指之间，指纹也有明显的区别，因此指纹可以用于身份鉴定。由于每次压印的方位不完全一样，着力点不同会带来不同程度的变形，又存在大量模糊指纹，如何正确提取指纹特征和实现正确匹配，是指纹识别技术的关键，这里不再赘述。
这里，为了更清楚的描述本申请的技术方案，以双屏手机的切换操作为例进行举例说明，如图3A所示，双屏手机包括位于正面的第一显示屏幕301，第一显示屏幕301可以作为移动终端的主显示屏。如图3B所示，双屏手机还包括位于背面的第二显示屏幕302a，第二显示屏幕302a作为副显示屏，第一显示屏幕和第二显示屏幕为相同尺寸的显示屏，可以实现相同的显示效果，与第一显示屏具有同等的显示地位。如图3C所示，第二显示屏幕302b的尺寸小于第一显示屏的尺寸，第二显示屏幕302b仅用于来电显示、消息显示等辅助显示操作。
场景一、如图4A所示，手机以第一显示屏幕401作为显示输出进行单屏显示，当前显示模式为单屏模式。用户手指在屏幕触控区域进行滑动操作，触控区域为整个第一显示屏幕401，用户手指在触控区域的中心其余执行向上滑动操作时，确定滑动方向为第二方向，第二方向对应的目标显示模式为镜像模式。 如图4B所示，执行第二方向的滑动操作后，控制第一显示屏幕401和第二显示屏幕402显示互为镜像的图像。
场景二、如图5A所示，手机以第一显示屏幕501作为显示输出进行单屏显示，当前显示模式为单屏模式。用户手指在屏幕触控区域进行滑动操作，触控区域为整个第一显示屏幕501，用户手指在触控区域的中心其余执行向下滑动操作时，确定滑动方向为第四方向，第四方向对应的目标显示模式为全屏模式。如图5B所示，当第一显示屏幕501的尺寸无法满足用户需求是，可以改变手机的物理结构使第一显示屏幕501和第二显示屏幕502位于同一平面，两块屏幕构成一块屏幕后，在触控区域内执行第四方向的滑动操作，可以将显示模式切换至全屏模式，显示效果如图5B所示。
采用本发明实施例提供的上述技术方案，能够通过检测到的滑动操作的滑动方向，确定多屏终端设备的显示模式，直接控制每一个显示屏幕由当前显示模式切换至目标显示模式，省去了繁琐的切换操作流程，提高了切换效率。
实施例二
本发明实施例进行进一步的举例说明，如图6所示，切换方法例如包括：步骤601至步骤604。
在步骤601中，采集目标对象对指纹识别区域执行滑动操作时产生的至少两幅指纹图像。
实际应用中，可以通过设置在指纹识别区域中的指纹传感器来采集指纹图像，指纹识别区域可以位于终端设备的显示区域之内，或者显示区域之外。
在步骤602中，基于采集的至少两幅指纹图像的中心位置信息，确定目标对象执行滑动操作的滑动方向。
实际应用中，如果指纹图像为规则图形，如矩形或圆形，指纹图像的中心位置为矩形中心或圆形圆心，如果是不规则图形，如不规则的接触区域，指纹图像的中心位置与实际图形相关。
在一实施例中，确定多幅指纹图像的中心位置坐标的移动轨迹，确定滑动方向。实际应用中，根据用户的操作习惯，用户手指进行滑动操作时，手指的移动轨迹一般为直线，因此，为了减少运算的复杂度，根据两幅指纹图像的中心位置坐标变化就可以确定移动轨迹。
示例性的，至少两幅指纹图像包括第一指纹图像和第二指纹图像，第一指纹图像取滑动操作中采集到的第一幅指纹图像，第二指纹图像取滑动操作中采 集到的最后一幅指纹图像。
实际应用中，滑动方向可以用方向值来指代，每一个方向值代表一种滑动方向，例如：方向值有F(1.2.3.4)，其中F1指代第一方向，F2指代第二方向，F3指代第三方向，F4指代第四方向。
在一实施例中，所述步骤602例如可以包括以下：
x>0且x>|y|，方向值输出F1；
x>0且x<y；或者x<0且|x|<y，方向值输出F2；
x<0且|x|>|y|，方向值输出F3；
x>0且x<-y，或者x<0且|x|<-y，方向值输出F4；
其中，x为第一指纹图像与第二指纹图像的中心位置的横坐标变化量；y为第一指纹图像与第二指纹图像的中心位置的纵坐标变化量。
在步骤603中，基于预设映射关系，确定至少两个显示屏幕所对应的目标显示模式。
实际应用中，映射关系可以包括以下：第一方向对应单屏模式，第二方向对应镜像模式，第三方向对应全屏模式，第四方向对应分屏模式。其中，显示模式也可以用模式值来表示，每一个模式值代表一种显示模式，模式值M(1.2.3.4)，其中M1指代单屏模式，M2指代镜像模式，M3指代全屏模式，M4指代分屏模式。映射关系表中包括方向值与模式值的映射关系，F1对应M1，F2对应M2，F3对应M3，F4对应M4。
本步骤例如可以包括：根据步骤602确定的方向值，在映射关系表中得到对应的模式值，从而确定目标显示模式。
在步骤604中，控制终端设备的每一个显示屏幕由当前显示模式切换至目标显示模式。
这里，若当前显示模式与滑动方向对应的目标显示模式不相同，控制屏幕显示从当前显示模式切换至滑动方向对应的目标显示模式；若不同，忽略本次切换操作，或者生成提示信息，以提示用户操作失败，请用户重新执行滑动操作。
实际应用中，步骤601至步骤604的执行主体可以为切换装置的处理器。
采用上述技术方案，能够通过检测到的滑动操作的滑动方向，控制显示模式的切换，省去了繁琐的操作流程，提高了切换效率，从而提高用户对多屏终端的显示切换体验。
