具体实施方式
为使本申请的目的和实施方式更加清楚，下面将结合本申请示例性实施例中的附图，对本申请示例性实施方式进行清楚、完整地描述，显然，描述的示例性实施例仅是本申请一部分实施例，而不是全部的实施例。
需要说明的是，本申请中对于术语的简要说明，仅是为了方便理解接下来描述的 实施方式，而不是意图限定本申请的实施方式。除非另有说明，这些术语应当按照其普通和通常的含义理解。

术语“模块”是指任何已知或后来开发的硬件、软件、固件、人工智能、模糊逻辑或硬件或/和软件代码的组合，能够执行与该元件相关的功能。
图1为根据实施例中显示设备与控制装置之间操作场景的示意图。如图1所示，用户可通过智能终端300或控制装置100操作显示设备200。
控制装置100可以是遥控器，遥控器和显示设备的通信包括红外协议通信或蓝牙协议通信，及其他短距离通信方式，通过无线或有线方式来控制显示设备200。用户可以通过遥控器上按键、语音输入、控制面板输入等输入用户指令，来控制显示设备200。
在一些实施例中，也可以使用智能终端300(如移动终端、平板电脑、计算机、笔记本电脑等)以控制显示设备200。例如，使用在智能设备上运行的应用程序控制显示设备200。
在一些实施例中，显示设备200还可以采用除了控制装置100和智能设备300之外的方式进行控制，例如，可以通过显示设备200设备内部配置的获取语音指令的模块直接接收用户的语音指令控制，也可以通过显示设备200设备外部设置的语音控制设备来接收用户的语音指令控制。
在一些实施例中，显示设备200还与服务器400进行数据通信。可允许显示设备200通过局域网(LAN)、无线局域网(WLAN)和其他网络进行通信连接。服务器400可以向显示设备200提供各种内容和互动。
图2示例性示出了根据示例性实施例中控制装置100的配置框图。如图2所示，控制装置100包括控制器110、通信接口130、用户输入/输出接口140、存储器、供电电源。控制装置100可接收用户的输入操作指令，且将操作指令转换为显示设备200可识别和响应的指令，起用用户与显示设备200之间交互中介作用。
图3示出了根据示例性实施例中显示设备200的硬件配置框图。
显示设备200包括调谐解调器210、通信器220、检测器230、外部装置接口240、控制器250、显示器260、音频输出接口270、存储器、供电电源、用户接口中的至少一些。
显示器260包括用于呈现画面的显示屏组件，以及驱动图像显示的驱动组件，用于接收源自控制器输出的图像信号，进行显示视频内容、图像内容以及菜单操控界面的组件以及用户操控UI界面。
显示器260可为液晶显示器、OLED显示器、以及投影显示器，还可以为一些投影装置和投影屏幕。
通信器220是用于根据各种通信协议类型与外部设备或服务器进行通信的组件。 例如：通信器可以包括Wifi模块，蓝牙模块，有线以太网模块等其他网络通信协议芯片或近场通信协议芯片，以及红外接收器中的至少一些。显示设备200可以通过通信器220与外部控制设备100或服务器400建立控制信号和数据信号的发送和接收。
用户接口，可用于接收控制装置100(如：红外遥控器等)的控制信号。
检测器230用于采集外部环境或与外部交互的信号。例如，检测器230包括光接收器，用于采集环境光线强度的传感器；或者，检测器230包括图像采集器，如摄像头，可以用于采集外部环境场景、用户的属性或用户交互手势，再或者，检测器230包括声音采集器，如麦克风等，用于接收外部声音。
外部装置接口240可以包括但不限于如下：高清多媒体接口(HDMI)、模拟或数据高清分量输入接口(分量)、复合视频输入接口(CVBS)、USB输入接口(USB)、RGB端口等任一个或多个接口。也可以是上述多个接口形成的复合性的输入/输出接口。
在一些示例性实施方式中，当显示设备还具备横竖屏旋转展示时，所述显示设备还包括一用于驱动显示器旋转的旋转组件。例如，旋转组件276可以包括驱动电机、旋转轴等部件。其中，驱动电机可以连接控制器250，受控制器250的控制输出旋转角度；旋转轴的一端连接驱动电机的动力输出轴，另一端连接显示器260，以使显示器260可以通过旋转组件276固定安装在墙壁或支架上。
旋转组件276还可以包括其他部件，如传动部件、检测部件等。其中，传动部件可以通过特定传动比，调整旋转组件276输出的转速和力矩，可以为齿轮传动方式；检测部件可以由设置在旋转轴上的传感器组成，例如角度传感器、姿态传感器等。这些传感器可以对旋转组件276旋转的角度等参数进行检测，并将检测的参数发送给控制器250，以使控制器250能够根据检测的参数判断或调整显示设备200的状态。实际应用中，旋转组件276可以包括但不限于上述部件中的一种或多种。
在一些示例性实施方式中，当用户想要通过触控所述显示器以输入指令时，显示设备还包括一触控组件277(图中未示出)。例如，可以通过增加触控组件277使显示设备200支持触控交互功能。通常，触控组件277可以与显示器260共同构成触摸屏。在触摸屏上用户可以通过触摸操作输入不同的控制指令。例如，用户可以输入点击、滑动、长按、双击等触控指令，不同的触控指令可以代表不同的控制功能。
为了实现上述不同的触摸动作，触控组件277可以在用户输入不同触摸动作时，产生不同的电信号，并将产生的电信号发送给控制器250。控制器250可以对接收到的电信号进行特征提取，从而根据提取的特征确定用户要执行的控制功能。
例如，当用户在应用程序界面中的任一程序图标位置输入点击触摸动作时，触控组件277将感应到触摸动作从而产生电信号。控制器250在接收到电信号后，可以先对电信号中触摸动作对应电平的持续时间进行判断，在持续时间小于预设时间阈值时，识别出用户输入的是点击触控指令。控制器250再对电信号产生的位置特征进行提取，从而确定触摸位置。当触摸位置在应用图标显示范围内时，确定用户在应用图标位置输入了点击触控指令。相应的，点击触控指令在当前场景下用于执行运行相应应用程序的功能，因此控制器250可以启动运行对应的应用程序。
又例如，当用户在媒资展示页面中输入滑动动作时，触控组件277同样将感应到的电信号发送给控制器250。控制器250先对电信号中触摸动作对应信号的持续时间进行判断。在确定持续时间大于预设时间阈值时，再对信号产生的位置变化情况进行判断，显然，对 于互动触摸动作，其信号的产生位置将发生变化，从而确定用户输入了滑动触控指令。控制器250再根据信号产生位置的变化情况，对滑动触控指令的滑动方向进行判断，控制在媒资展示页面中对显示画面进行翻页，以显示更多的媒资选项。进一步地，控制器250还可以对滑动触控指令的滑动速度、滑动距离等特征进行提取，并按照所提取的特征进行翻页的画面控制，以达到跟手效果等。
同理，对于双击、长按等触控指令，控制器250可以通过提取不同的特征，并通过特征判断确定触控指令的类型后，按照预设的交互规则执行相应的控制功能。在一些实施例中，触控组件277还支持多点触控，从而使用户可以在触摸屏上通过多指输入触摸动作，例如，多指点击、多指长按、多指滑动等。
对于上述触控动作还可以配合特定的应用程序，实现特定的功能。例如，当用户打开“演示白板”应用后，显示器260可以呈现绘图区域，用户可以通过滑动触控指令在绘图区域中画出特定触控动作轨迹，控制器250则通过触控组件277检测的触控动作，确定触控动作图案，并控制显示器260实时进行显示，以满足演示效果。
控制器250和调谐解调器210可以位于不同的分体设备中，即调谐解调器210也可在控制器250所在的主体设备的外置设备中，如外置机顶盒等。
控制器250，通过存储在存储器上中各种软件控制程序，来控制显示设备的工作和响应用户的操作。控制器250控制显示设备200的整体操作。例如：响应于接收到用于选择在显示器260上显示UI对象的用户命令，控制器250便可以执行与由用户命令选择的对象有关的操作。
对象可以是可选对象中的任何一个，例如超链接、图标或其他可操作的控件。与所选择的对象有关操作有：显示连接到超链接页面、文档、图像等操作，或者执行与所述图标相对应程序的操作。
在一些实施例中，用户可在显示器260上显示的图形用户界面(GUI)输入用户命令，则用户输入接口通过图形用户界面(GUI)接收用户输入命令。或者，用户可通过输入特定的声音或手势进行输入用户命令，则用户输入接口通过传感器识别出声音或手势，来接收用户输入命令。
“用户界面”可以指应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接受形式之间的转换。用户界面常用的表现形式是图形用户界面(Graphic User Interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的一个图标、窗口、控件等界面元素，其中控件可以包括图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。在一些实施例中，系统可以包括内核(Kernel)、命令解析器(shell)、文件系统和应用程序。内核、shell和文件系统一起组成了基本的操作系统结构，它们让用户可以管理文件、运行程序并使用系统。上电后，内核启动，激活内核空间，抽象硬件、初始化硬件参数等，运行并维护虚拟内存、调度器、信号及进程间通信(IPC)。内核启动后，再加载Shell和用户应用程序。应用程序在启动后被编译成机器码，形成一个进程。
显示设备是基于Internet应用技术，具备开放式操作系统与芯片，拥有开放式应用平台，可实现双向人机交互功能，集影音、娱乐、数据等多种功能于一体的产品，用于满足用户多样化和个性化需求。
触屏显示设备的显示器为触摸屏显示器(Touch Screen)，触摸屏显示器可以让用户只要用手指轻轻地碰显示器就能实现对主机操作，这样摆脱了键盘、鼠标、遥控器操作，使人机交互更为直截了当。
在具备触控功能的显示设备中，一般支持显示图片的旋转，例如，在电子白板、绘画、以及图片浏览相关的应用(筒仓)中，用户可以通过用户输入用于将图片旋转的指令，从而当图片旋转一定的角度。例如，通至少两个手指的相对旋转。
其中，该至少两指可以初始触控在触控组件上的角度为一个初始状态，相对于显示的固定位置而言，具备初始角度。
初始角度为用户手指转动前两根手指之间的连接线与预置参考线之间的夹角；下面结合具体的实例对初始角度的计算过程作以说明。
为了方便描述，本实施例对两根手指进行区分，其中一根手指称之为轴手指，手指转动的过程中以轴手指为轴进行转动；另一根手指称之为转动手指，手指转动的过程中以转动手指绕着轴手指进行转动。通常用户的拇指称之为轴手指。
在一些可行性实施例中，预置参考线可以是平行于显示器宽的线段，在一些可行性实施例中，预置参考线可以是平行于显示器高的线段。本实施例中以平行于显示器宽的线段作为预置参考线进行说明。
图4为根据一可行性实施例示出的显示设备与用户交互的流程图；
显示器被配置为执行步骤S101显示图片；
本实施例示出的技术方案并不对图片的种类作以限定。例如，在一些可行性实施例中图片可以是显示设备内存储的照片，视频的帧画面。在一些可行性实施例中图片用户打开APP的首页。在实际应用的过程中凡是可以显示在显示器上的画面均可称之为图片，在此申请人不做过多的限定。
用户执行步骤S102至少两个手指触控显示器；
用户需要对显示器上展示的图片进行旋转时，用户的手指会触控显示器。
控制器被配置为执行步骤S103基于用户至少两根手指接触显示器并且至少一根手指移动所形成的旋转手势，生成第一旋转角度。
生成第一角度的是实现方式有多种。
例如，图5为根据一可行性实施例示出的第一旋转角度的计算方式的流程图，响应于用户的至少两根手指触控显示器，控制器被配置为执行步骤S11计算初始角度，初始角度为用户手指转动前两根手指之间的连接线与预置参考线之间的夹角；
本申请实施例示出的技术方案中，以用户两根手指同时触控显示器作为图片旋转的触发条件。用户每个手指触控显示器时，显示器会发送一个触点信息至控制器，触点信息至少用户触控显示器的位置。用户需要控制图片旋转时，通常会在预置时间内用两个手指触控显示器，如果用户两根手指触控显示器的时间间隔较长，可能是用户用于误操作触控到显示器。为了避免上述情况的发生，本申请实施例示出的方案中，只有控制器在预置时间内接收到两个触点信息的情况下，控制器才开始计算初始角度。其中，预置时间可以根据需求设定，在此申请人不做过多的限定。
举例说明，在一可行性实施例中预置时间可以是5s，控制器接收到第一个触点信息时，启动定时器，当定时器记录的时间为3s时，控制器接收到第二触点信息。在此情况下，控制器根据第一触点信息和第二触点信息计算初始角度。
在一可行性实施例中预置时间可以是5s，控制器接收到第一个触点信息时，启动定时器，当定时器记录的时间为30s时，控制器接收到第二触点信息，在此情况下，用户不计算初始角度。
在一可行性实施例中，控制器接收到两个触点信息时，不再继续接收触点信息。举例说明，控制器接收到第一个触点信息时，启动定时器，当定时器记录的时间为3s时，控制器接收到第二触点信息，此时控制器关闭定时器。在定时器关闭后，控制器忽略后续接收到的触点信息。
图6为根据一可行性实施例示出的图片旋转过程中显示器展示界面的示意图。初始状态时，显示器展示一横屏图片。用户需要对该图片进行旋转，用户用拇指和食指同时触控显示器。具体的可以参考图6中示意图(a)，其中，拇指(可以称之为轴手指)触控的位置为P1，食指(可以称之为转动手指)触控的位置为P2。显示器将P1的触点信息(X1，Y1)，P2的触点信息(X2，Y2)发送给控制器。控制器根据P1的触点信息(X1，Y1)，P2的触点信息(X2，Y2)计算初始角度。预置参考线为平行于显示器宽的线段，预置参考线的一顶点与P1重合(X1，Y1)，预置参考线的另一顶点与P2具有相同的纵坐标，与P1具有相同的横坐标即(X1，Y2)。
最终求得初始角度＝α＝(Y2-Y1)/[(Y2-Y1) 2+(X2-X1) 2] 1/2。
值得注意的是，本实施例仅是示例性的介绍一种初始角度的计算方法，在实际应用的过程中初始角度的技术方法可以是但不限于上述方法。
响应于手指的转动，控制器被配置为执行步骤S12计算当前角度，当前角度为用户手指旋转时两手指之间的连接线与预置参考线之间的夹角；
检测手指是否发生转动的方式有多种，例如，在一可行性实施例中显示器可以将转动手指单位时间内移动的位移发送给控制器。控制器通过转动手指单位时间内移动的位移确定手指是否发生转动。在实际应用的过程中，控制器可以采用其他方式确定用户的手指是否发生移动，在此申请人不做过多的限定。
下面结合图6的中示意图(b)对当前角度的计算过程作以说明。用户以轴手指为中心轴(对应的触点为P1)，转动手指绕轴手指转动，此时显示器的展示界面可以参阅图6中的中示意图(b)。显示器将P1的触点信息(X1，Y1)，P3的触点信息(X3，Y3)发送给控制器，本实施例中预置参考线为平行于显示器宽的线段，预置参考线的一顶点与P1重合(X1，Y1)，预置参考线的另一顶点与P3具有相同的纵坐标，与P1具有相同的横坐标即(X1，Y3)。
最终求得当前角度＝β＝(Y3-X1)/[(Y3-Y1) 2+(X3-X1) 2] 1/2。
控制器被配置为执行步骤S13根据初始角度和当前角度计算第一旋转角度；
第一旋转角度等于当前角度与初始角度的差值；
具体的，第一旋转角度＝β-α。
控制器被配置为执行步骤S14根据第一旋转角度绘制旋转图片,使得图片的旋转角度与用户手指转动的角度具有相关性，或者保持一致；
根据第一旋转角度绘制旋转图片的实现方式有多种。
例如，在一可行性实施例中，控制器设置有OSD(on-screen display，屏幕菜单式调节方式)层；OSD层被配置为根据第一旋转角度控制图片旋转，得到旋转图片，直接输出旋转图片至显示器，以使得显示器对旋转图片进行展示。
图片旋转过程可以参阅图6中的示意图(c)和示意图(d)，具体的，OSD层根据第一旋转角度控制图片旋转得到的旋转图片可以参阅图6中的示意图(c)，最终显示在显示器上的效果图可以参阅图6中的示意图(d)。
例如，在一可行性实施例中，控制器设置有video层；video层被配置为基于图片数据和第一旋转角度渲染旋转图片。video层无法控制显示器展示图片旋转，因此，每次用户控制图片旋转时，video层均需要基于图片数据和第一旋转角度渲染旋转图片。
例如，图7为根据一可行性实施例示出的第一旋转角度的计算方式的流程图。
当显示器展示图片时，响应于用户的至少两根手指触控显示器，控制器被配置为执行步骤S21获取初始参考线，初始参考线为用户手指转动前两根手指之间的连接线；
响应于手指的转动，控制器被配置为执行步骤S22获取当前参考线，当前参考线为用户手指旋转时两手指之间的连接线；
控制器被配置为执行步骤S23根据初始参考线和当前参考线计算第一旋转角度。
第一旋转角度的计算方式可以参阅上述实施例，在此便不赘述。
控制器被配置为执行步骤S104控制显示器展示旋转图片，以使得第二旋转角度与第一旋转角度相关联，第二旋转角度为旋转图片的旋转角度；
最终显示旋转图片的效果图可以参阅图14中的示意图(d)。
通常用户在控制图片旋转的过程中，用户的手指可能沿顺时针方向旋转，也可能沿逆时针方向旋转。为了图片的旋转方向与用户手指的旋转方向匹配，本申请实施例示出的技术方案中，控制器还被配置为生成旋转标识，进而使得控制器可以根据旋转标识确定图片的旋转方向，以使得图片的旋转方向与用户手指的旋转方向匹配，进而提升用户的体验感。
图8为根据一可行性实施例示出的控制器控制图片旋转过程的流程图。从图中可以看出在本实施例示出的方案中控制器被进一步配置为执行步骤S31～S341/S342。
步骤S31根据初始角度和当前角度计算第一旋转角度；
根据初始角度和当前角度计算第一旋转角度的实现方式可以参阅上述实施例，在此便不赘述。
步骤S32生成旋转标识，旋转标识为第一旋转角度与旋转角度绝对值的比值，旋转角度绝对值为旋转角度的绝对值；
生成旋转标识的实现方式有多种。例如，在一可行性实施例在中，可以计算旋转角度绝对值，根据旋转角度和旋转角度绝对值的比值生成旋转标识。
举例说明，在一可行性实施例中初始角度α＝60度，当前角度β＝20度，计算出第一旋转角度β-α＝20-60＝-40，第一旋转角度绝对值等于40度，旋转标识＝-40/40＝-1；
在一可行性实施例中初始角度α＝60度，当前角度β＝90度，计算出第一旋转角度β-α＝90-60＝30，第一旋转角度绝对值等于30度，旋转标识＝30/30＝1；
再例如，在一可行性实施例在中，可以计算旋转角度绝对值，根据第一旋转角度与旋转角度绝对值的差值生成旋转标识。
举例说明，在一可行性实施例中初始角度α＝60度，当前角度β＝20度，计算出第一旋转角度β-α＝20-60＝-40，第一旋转角度绝对值等于40度，旋转标识＝-40-40＝-80；
在一可行性实施例中初始角度α＝60度，当前角度β＝90度，计算出第一旋转角度β-α＝90-60＝30，第一旋转角度绝对值等于30度，旋转标识＝30-30＝0；
值得注意的是，本实施例仅是示例性的示出两种旋转标识的生成方法，在实际应用的 过程中，旋转标识的生成方法可以是但不限于上述两种方式。
S33判断旋转标识是否大于或等于0；
如果旋转标识大于或等于0，则执行步骤S341控制图片在顺时针方向转动旋转角度；
如果旋转标识小于0，则执行步骤S342控制图片在逆时针方向转动旋转角度。
下面结合具体的实例对图片的旋转过程作进一步的描述。
图9a为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，初始角度α＝30度，当前角度β＝-30。控制器计算得到旋转角度-60，旋转角度绝对值等于60度，旋转标识＝-60/60＝-1(小于0)，控制器控制图片逆时针旋转60度。
图9b为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，初始角度α＝30度，当前角度β＝60控制器计算得到旋转角度30，旋转角度绝对值等于30度，旋转标识＝30/30＝1(大于0)，控制器控制图片顺时针旋转30度。
本实施例中，控制器可以根据第一旋转角度确定旋转标识，然后基于旋转标识确定控制图片顺时针旋转还是逆时针旋转，进而实现图片的旋转方向与用户手指的旋转方向匹配，用户体验感较好。
当用户终止旋转图片时，用户会输入控制图片终止旋转的旋转手势，本实施例中终止旋转的旋转手势为用户将触控显示器的手指脱离显示器，此时，与显示器相触控的手指少于两根。本申请实施例示出的方案对用户少于两根手指触控显示器的应用场景下，图片的显示状态做了进一步的限定，以进一步的提升用户的体验感。
图10为根据一可行性实施例示出的用户少于两根手指触控显示器的应用场景下，控制图片旋转的流程图。从图中可以看出在本实施例示出的方案中控制器被进一步配置为执行步骤S41～S421/S422。
响应于用户少于两根手指触控显示器，执行步骤S41判断判第一断旋转角度是否小于或等于旋转阈值。
本实施例中旋转阈值可以根据需求设定，例如，在一些可行性实施例中旋转阈值可以为20度，在一些可行性实施例中旋转阈值可以为45度。
如果第一旋转角度小于或等于旋转阈值，则步骤S421控制图片旋转回至(或保持)初始显示状态，初始显示状态为用户手指转动前图片的状态；
下面结合具体的实例，对图片的旋转过程做进一步的说明。图11为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，初始角度α＝30度，当前角度β＝60。控制器计算得到第一旋转角度30，控制器控制图片顺时针旋转30度。本实施例中旋转阈值为45度(第一旋转角度小于或等于旋转阈值)，响应于用户少于两根手指触控显示器，控制图片旋转回至(或保持)初始状态。
如果第一旋转角度大于旋转阈值，则步骤S422控制图片旋转目标角度，目标角度与第一旋转角度相关。
目标角度的生成方法有多种，图12为根据一可行性实施例示出的目标角度生成方法的流程图，控制器被进一步配置为执行步骤S51～S53。
步骤S51根据第一旋转角度和旋转阈值计算超出角度；
超出角度的计算过程可以为：旋转角度delta＝β-α，超出角度over＝Math.max(|delta|,T)–T，其中T为旋转阈值。
举例说明，在一可行性实施例中，旋转阈值为20，初始角度α＝30度，当前角度β＝60， delta＝β-α＝60-30＝30度(第一旋转角度大于旋转阈值)，超出角度over＝Math.max(30,20)–20＝10度。
在一可行性实施例中，旋转阈值为45，初始角度α＝30度，当前角度β＝60，delta＝β-α＝60-30＝30度(第一旋转角度大于旋转阈值)，超出角度over＝Math.max(30,45)–45＝0度。
步骤S52计算超出倍数，超出倍数＝Math.ceil(over/90)，over为超出角度；
举例说明，在一可行性实施例中，over＝10度，超出倍数＝Math.ceil(10/90)＝1；
在一可行性实施例中，over＝0度，超出倍数＝Math.ceil(0/90)＝0。
步骤S53根据超出倍数计算目标角度。
根据超出倍数计算目标角度的实现方式可以是：计算最终旋转到的目标角度target＝direction*times*90。
举例说明，在一可行性实施例中，over＝10度，times＝Math.ceil(10/90)＝1；target＝1*90＝90。
在一可行性实施例中over＝0度，超出倍数＝Math.ceil(0/90)＝0。target＝0*90＝90。
根据超出倍数计算目标角度的实现方式也可以是：计算最终旋转到的目标角度target＝direction*times*90，如果旋转标识大于或等于0，direction＝1；如果旋转标识小于0，direction＝-1。
下面结合具体的实例对图片的旋转过程作进一步的描述。
图13a为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，初始角度α＝30度，当前角度β＝60。控制器计算得到旋转角度30，控制器控制图片顺时针旋转60度。此时，用户将手指脱离显示器，本实施例中旋转阈值为20度，响应于用户少于两根手指触控显示器，第一旋转角度大于旋转阈值，控制器计算超出倍数＝Math.ceil(30-20/90)＝1，然后计算目标角度＝1*90，因此，响应于用户少于两根手指触控显示器，控制器控制图片旋转90度。
图13b为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，初始角度α＝30度，当前角度β＝150。控制器计算得到第一旋转角度120，控制器控制图片顺时针旋转120度。此时，用户将手指脱离显示器，本实施例中旋转阈值为20度，响应于用户少于两根手指触控显示器，旋转角度大于旋转阈值。控制器计算超出倍数＝Math.ceil(120-20/90)＝2，然后计算目标角度＝2*90，因此，响应于用户少于两根手指触控显示器，控制器控制图片旋转180度。
当用户的手指脱离显示器时，图片还可以有其他的展示形式，例如在一可行性实施例中，响应于用户少于两根手指触控显示器，控制器不对旋转图片做调整。
上述图片旋转的过程中，图片的大小未发生变化，因此在旋转角度不为0的情况下，显示器仅能展示部分图片。当然在另一些实施例中，图片的显示比例还可以根据指示旋转的角度进行相应的缩放，以使图片还能完整展示在显示器上。上述两种显示方式仅为一种示例性的说明，还可以包括其他可预见的显示方式。
具体的，本申请实施例示出一种显示设备，显示设备的控制器可以根据第一旋转角度确定图片的缩放倍数，以每次得到的旋转图片均可以全部展示在显示器内，具体的展示效果可以参阅图14，图14为图片旋转过程中，显示器的展示效果图。

S71判断显示器的宽高比和图片的宽高比是否一致；

显示器的宽高比和图片的宽高比一致，执行步骤S721根据第一旋转角度和显示器的高计算当前对角线值；
举例说明，图17a为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，显示器的宽高比为16/9,图片的宽高比为16/9；图片在显示器上的展示效果可以参阅图17a中的左图。用户通过旋转手指控制器图片旋转α，旋转后图片在显示器上的展示效果可以参阅图17a中的右图，旋转后的图片的宽与显示器的宽的夹角为α，旋转后的图片的对角线与图片宽的夹角为γ,本实施例中第一旋转角度小于90°时，当前对角线长度根据正弦函数可得d(α)＝dh/sin(α+γ)；其中，γ＝arc tan(h/w)，其中，dh为显示器的高，h为图片的高，w为图片的宽。
举例说明，图17b为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，显示器的宽高比为16/9,图片的宽高比为16/9；图片在显示器上的展示效果可以参阅图17b中的左图。用户通过旋转手指控制器图片旋转α，旋转后图片在显示器上的展示效果可以参阅图17a中的右图，旋转后的图片的宽与显示器的宽的夹角为α，旋转后的图片的对角线与图片宽的夹角为γ,本实施例中第一旋转角度大于90°时，当前对角线长度根据正弦函数可得d(α)＝dh/sin(α-γ)；其中，γ＝arc tan(h/w)，其中，dh为显示器的高，h为图片的高，w为图片的宽。
显示器的宽高比和图片的宽高比不一致，执行步骤S722根据第一旋转角度和显示器高计算第一对角线值，根据第一旋转角度和显示器的高计算第二对角线值；
步骤S53在第一对角线值和第二对角线值中选取较小的数值作为当前对角线值；
举例说明，图18a为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，显示器的宽高比为16/9,图片的宽高比为7/2；图片在显示器上的展示效果可以参阅图18a中的左图。用户通过旋转手指控制器图片旋转α(α<90度)，旋转后图片在显示器上的展示效果可以参阅图18a中的右图，旋转后的图片的宽与显示器的宽的夹角为α，旋转后的图片的对角线与图片宽的夹角为γ,本实施例中第一旋转角度小于90°时，第一对角线值d(α)1＝dh/sin(α+γ)，第二对角线值d(α)2＝dw/sin(α+γ)； 本实施例中，d(α)2小于d(α)1，因此选取d(α)2为当前对角线值。
图18b为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，显示器的宽高比为16/9,图片的宽高比为7/2；图片在显示器上的展示效果可以参阅图18a中的左图。用户通过旋转手指控制器图片旋转α(α>90度)，旋转后图片在显示器上的展示效果可以参阅图18b中的右图，旋转后的图片的宽与显示器的宽的夹角为α，旋转后的图片的对角线与图片宽的夹角为γ,本实施例中第一旋转角度大于90°时，第一对角线值d(α)1＝dh/sin(α-γ)，第二对角线值d(α)2＝dw/sin(α-γ)；本实施例中，d(α)2小于d(α)1，因此选取d(α)2为当前对角线值。
图19a为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，显示器的宽高比为16/9,图片的宽高比为2/1；图片在显示器上的展示效果可以参阅图18a中的左图。用户通过旋转手指控制器图片旋转α(α<90度)，旋转后图片在显示器上的展示效果可以参阅图19a中的右图，旋转后的图片的宽与显示器的宽的夹角为α，旋转后的图片的对角线与图片宽的夹角为γ,本实施例中第一旋转角度小于90°时，第一对角线值d(α)1＝dh/sin(α+γ)，第二对角线值d(α)2＝dw/sin(α+γ)；本实施例中，d(α)1小于d(α)2，因此选取d(α)1为当前对角线值。
图19b为根据一可行性实施例示出的图片旋转过程中，显示器展示界面的示意图。本实施例中，显示器的宽高比为16/9,图片的宽高比为2/1；图片在显示器上的展示效果可以参阅图18a中的左图。用户通过旋转手指控制器图片旋转α(α>90度)，旋转后图片在显示器上的展示效果可以参阅图19b中的右图，旋转后的图片的宽与显示器的宽的夹角为α，旋转后的图片的对角线与图片宽的夹角为γ,本实施例中第一旋转角度大于90°时，第一对角线值d(α)1＝dh/sin(α-γ)，第二对角线值d(α)2＝dw/sin(α-γ)；本实施例中，d(α)1小于d(α)2，因此选取d(α)1为当前对角线值。
步骤S63根据初始对角线值和当前对角线值计算图片的缩放倍数。
缩放倍数scale＝d(α)/d。
本申请实施例示出的显示设备，显示设备的控制器可以根据第一旋转角度确定图片的缩放倍数，以每次得到的旋转图片均可以全部展示在显示器内，用户体验感较好。
在一些应用场景下，用户的手指抖动等原因造成显示器展示的旋转图片在旋转的过程中发生抖动，影响用户的体验感，为了进一步提升用户的体验感，本实施例示出一种图片防抖方法，具体的可以参阅图20，图20为根据一可行性实施例示出的图片防抖方法的流程图，其中控制器被进一步配置为执行步骤S81～S851/S852。
响应于手指的转动，执行步骤S81统计旋转时间；
S82根据旋转时间和预测旋转速率计算预测角度；
举例说明，在一可行性实施例中旋转时间为T,第一旋转角度为α，预测角度＝(α/T)*当前时间+初始角度。
S83计算预测角度与第一旋转角度的差值；所述第一旋转角度的计算方法可以参阅上述实施例在此便不赘述。
S84判断差值是否小于或等于角度差阈值；
如果预测角度与第一旋转角度的差值小于或等于角度差阈值，则执行步骤S851控制所述图片旋转，以使得第二旋转角度与所述第一旋转角度相关联，所述第二旋转角度为所述旋转图片的旋转角度。
如果预测角度与第一旋转角度的差值大于角度差阈值，则执行步骤S852不控制图片旋转；
如果预测角度与第一旋转角度的差值小于或等于角度差阈值，则执行步骤S851控制所述图片旋转，以使得第二旋转角度与所述第一旋转角度相关联，所述第二旋转角度为所述旋转图片的旋转角度。
如果预测角度与第一旋转角度的差值大于角度差阈值，则执行步骤S852不控制图片旋转；
本实施例示出的技术方案，当预测角度与第一旋转角度的差值大于角度差阈值时，可能由于用户的误操作因引起的图片旋转，在此情况下，控制器根据不根据初始角度和当前角度计算第一旋转角度。采用本实施例示出方案一方面可以降低控制器的数据处理量，另一方可以避免由于用户的误操作导致的图片抖动，用户体验感较好。
在另一些示例性实施方式中，当显示设备同时具备旋转组件276和触控组件277时，可实现手动旋转所述显示器。可旋转显示设备是一种新型智能电子设备，主要包括显示器以及旋转组件。其中，显示器通过旋转组件固定在墙壁或支架上，可通过旋转组件调节显示器的摆放角度，以适应不同宽高比的显示画面。用户可以在横屏状态下显示宽高比大于1的横向媒资，也可以在竖屏状态下显示宽高比小于1的竖向媒资。当然，当在横屏状态下用户点击竖屏媒资，或者进入竖向应用，或者用户输入旋转指令等情况时，可旋转显示设备可以从横屏状态旋转至竖屏状态，反之亦然。
例如，多数情况下显示器横向放置，以显示宽高比为16:9的多媒体资源，如电影、电视剧等视频画面。当视频画面的宽高比为9:16的多媒体资源，如短视频、漫画等画面时，横向放置的显示器需要对画面进行缩放，且在显示器的两侧显示黑色区域。因此，可以通过旋转组件将显示器竖向放置，以适应9:16比例的视频画面。
例如，当初始显示器为横屏显示状态，当用户基于手势发出旋转显示器的指令时，触控组件接收旋转手势指令，再由控制器控制所述旋转组件将显示器旋转至竖屏状态，以达到竖屏显示媒体资源的效果。
在一些情况下，旋转显示器的手势和旋转图片的手势是一样的，均是至少两指头的触控。而当用户此旋转指令时，显示设备需要区分场景和设计针对性的作出反应。例如，当在图片浏览界面，只支持手势旋转图片，不支持手势旋转能显示器。当用户输出旋转指令时，响应于用户的输入而旋转图片。当然在这种场景下，并不是将旋转显示器的指令全部禁用，还可以通过按键或者语音的方式触发旋转显示器的指令。

判断旋转组件是否具备带动显示器旋转的条件的实现方式还可以是：
例如，在实际应用的过程中，为了防止由于用户的误操作而引起的显示设备的旋转，可以在显示设备中设置有旋转开关，当旋转开关处于连通状态时，控制器可以控制旋转组件带动显示器旋转，当旋转开关处于斩断状态时，控制器无法控制旋转组件旋转。在一可行性实施例中，如果旋转开关处于斩断状态，则控制显示器展示提示信息，本实施例中提示信息用于提示用户旋转开关处于斩断状态。
例如，在一可行性实例中，控制器可以读取旋转开关的状态，如果旋转开关处于斩断状态，则控制显示器展示提示信息，提示信息用于提示用户旋转开关处于斩断状态；如果旋转开关处于连通状态，控制器控制旋转组件带动显示器旋转。
