请参阅图1至图2，本申请实施方式提供一种显示设备100的控制方法，显示设备100包括柔性显示屏80与能够相对柔性显示屏80转动的摄像头81。控制方法包括：
S10：控制摄像头81转动并获取场景图像；
S20：判断场景图像中是否存在人体；
S30：在场景图像中存在人体时，根据场景图像与摄像头81的运动信息获取人体相对于柔性显示屏80的相对位置；及
S40：根据相对位置控制柔性显示屏80的部分区域进行显示。
请继续参阅图1，本申请实施方式提供了一种显示设备100。显示设备100包括柔性显示屏80与能够相对柔性显示屏80转动的摄像头81。请参阅图3，显示设备100还包括第一控制模块10、第一判断模块20、第一获取模块30及第二控制模块40。S10可以由第一控制模块10实现，S20可以由第一判断模块20实现，S30可以由第一获取模块30实现，S40可以由第二控制模块40实现。也即是说，第一控制模块10可用于控制摄像头81转动并获取场景图像；第一判断模块20可用于判断场景图像中是否存 在人体；第一获取模块30可用于在场景图像中存在人体时，根据场景图像与摄像头81的运动信息获取人体相对于柔性显示屏80的相对位置；第二控制模块40可用于根据相对位置控制柔性显示屏80的部分区域进行显示。
请结合参阅图4，本申请实施方式提供了一种显示设备100。显示设备100包括处理器82、柔性显示屏80与能够相对柔性显示屏80转动的摄像头81。S10、S20、S30及S40可以由处理器82实现。也即是说，处理器82可用于控制摄像头81转动并获取场景图像、判断场景图像中是否存在人体、在场景图像中存在人体时，根据场景图像与摄像头81的运动信息获取人体相对于柔性显示屏80的相对位置、以及根据相对位置控制柔性显示屏80的部分区域进行显示。
本申请实施例的显示设备100包括但不限于手机、平板电脑、笔记本电脑、智能音响、可穿戴智能设备(如手环，头戴显示器等)等。本实施方式中，显示设备100以智能音响为例进行说明。
具体地，摄像头81可以在用户打开显示设备100后自动运行。请参见图1，柔性显示屏80呈圆柱筒状，摄像头81运行的方式可以是以平行于柔性显示屏80的中心轴的一根直线为转轴83进行自转；或者，请参见图5，摄像头81运行的方式也可以是以平行于柔性显示屏80的中心轴的一根直线为转轴83并按照一定的间距环绕该转轴83转动(即摄像头81运动的轨迹为圆形)，摄像头81的运动轨迹也可以为椭圆形或者方形等形式。
由于摄像头81在转动过程不断地获取场景图像，当用户(人体)靠近显示设备100时，摄像头81就会把用户拍摄在场景图像内。显示设备100通过图像识别算法对摄像头81所获取的场景图像进行逐一识别，就能够识别到场景图像中是否存在人体。显示设备100对人体的检测所采用的图像识别算法可以基于人体轮廓检测算法来实现的，如果检测的场景图像中存在与人体轮廓相似时，即可确定场景图像中存在人体。
需要说明的是，当显示设备100检测到场景图像中存在人体时，第一控制模块10(处理器82)可以控制摄像头81停止转动。当场景图像中不存在人体时，显示设备100可以继续控制摄像头81转动并继续获取场景图像，重新判断场景图像中是否存在人体。在其他实施方式中，当显示设备100开启后，摄像头81可以一直处于转动状态，具体地，当显示设备100检测到场景图像中存在人体时，第一控制模块10(处理器82)可以控制摄像头81保持转动并持续检测获取的场景图像中是否存在其他人体。
显示设备100可以根据场景图像中的人体在场景图像中的位置信息以及摄像头81在获取到该场景图像时的运动信息得到人体相对于柔性显示屏80的相对位置。
一般地，第二控制模块40或处理器82可以根据人体相对于柔性显示屏80的相对 位置控制柔性显示屏80的能够被人体看到的可视区域进行显示，并控制柔性显示屏80的不能够被人体看到的区域不显示画面。其中，人体相对柔性显示屏80的相对位置可包括：人体相对于柔性显示屏80之间的距离、在同一坐标系下，人体与坐标原点的连线和柔性显示屏80的一预设位置(如图10或图14所示中，预设位置为柔性显示屏80与X轴的交点)与坐标原点的连线所形成的夹角。
本申请实施方式的控制方法和显示设备100通过能够转动的摄像头81获取显示设备100周围的场景图像，并根据场景图像确定是否存在人体，以及在显示设备100周围存在人体时控制柔性显示屏80的能够被人体看到的区域进行显示图像画面，从而使得用户能够从柔性显示屏80上看到完整的图像。此外，控制方法和显示设备100还控制柔性显示屏80中除可视区域外的其他区域不显示，还有利于降低显示设备100的耗电量和提高显示设备100的续航能力。
请参阅图6，在某些实施方式中，在场景图像中存在人体时，控制方法还包括：
S80：判断场景图像是否包含人脸图像或人眼图像；及
在人体包含人脸图像和/或人眼图像时，执行根据场景图像与摄像头81的运动信息获取人体相对于柔性显示屏80的相对位置的步骤(步骤S30)。
请结合参阅图7，在某些实施方式中，显示设备100还包括第二判断模块21。S80可以由第二判断模块21实现。也即是说，第二判断模块21可用于判断场景图像是否包含人脸图像或人眼图像。
请结合参阅图4，在某些实施方式中，S80可以由处理器82实现。也即是说，处理器82还可用于判断场景图像是否包含人脸图像或人眼图像。
若场景图像中的人体包含人脸图像，则确定用户观看显示设备100。在确定用户观看显示设备100后再获取人体相对于柔性显示屏80的相对位置、及控制柔性显示屏80能够被用户看到可视区域进行显示，从而避免人体不观看时显示设备100也显示图像，并降低了显示设备100的耗电量和提高了显示设备100的续航能力。在其他实施方式中，若场景图像中的人体包含人眼图像，则能够更准确地确定用户在观看显示设备100。
第二判断模块21(处理器82)可以通过图像识别算法实现对场景图像中是否存在人脸或人眼。其中，人脸和人眼的检测可以基于人脸轮廓或人眼轮廓进行检测。
需要说明的是，在第二判断模块21(处理器82)判断到场景图像中不含人脸图像或人眼图像时，第一控制模块10(处理器82)可以继续控制摄像头81转动并重新获取场景图像，第二判断模块21(处理器82)则重新识别所获取的场景图像中是否包含人脸图像或人眼图像。
请参阅图8，在某些实施方式中，根据场景图像与摄像头81的运动信息获取人体 相对于柔性显示屏80的相对位置，包括：
S31：以摄像头81的转轴为原点建立一个坐标系；
S32：获取摄像头81在坐标系中的转动角度；
S33：获取人体在场景图像中的像素位置；及
S34：根据像素位置与转动角度获取在坐标系下人体相对于柔性显示屏80的相对位置。
请结合参阅图9，在某些实施方式中，第一获取模块30包括建立单元31、第一获取单元32、第二获取单元33及第三获取单元34。S31可以由建立单元31实现，S32可以由第一获取单元32实现，S33可以由第二获取单元33实现，S34可以由第三获取单元34实现。也即是说，建立单元31可用于以摄像头81的转轴为原点建立一个坐标系；第一获取单元32可用于获取摄像头81在坐标系中的转动角度；第二获取单元33可用于获取人体在场景图像中的像素位置；第三获取单元34可用于根据像素位置与转动角度获取在坐标系下人体相对于柔性显示屏80的相对位置。
请结合参阅图4，在某些实施方式中，S31、S32、S33及S34可以由处理器82实现。也即是说，处理器82可用于以摄像头81的转轴为原点建立一个坐标系、获取摄像头81在坐标系中的转动角度、获取人体在场景图像中的像素位置、及根据像素位置、转动角度获取在坐标系下人体相对于柔性显示屏80的相对位置。
本申请的实施方式的摄像头81的运行方式以柔性显示屏80的中心轴为转轴进行自转作为例子进行举例说明。其中，摄像头81的转动方向为顺时针方向。当然，其他实施方式中，摄像头81的转动方向也可以为逆时针方向。
请结合参阅图10，具体地，建立单元31(处理器82)以柔性显示屏80的中心轴作为坐标系的原点O，摄像头81处于初始位置时的光轴84作为坐标系的X轴建立坐标系。需要说明的是，摄像头81的初始位置通过出厂设置预先设置，所以该坐标系为一个预设坐标系，并且该坐标系建立后并不随摄像头81的转动而发生改变。
请结合图11及图12，当摄像头81获取的场景图像中存在人体时，沿顺时针方向上摄像头81的光轴与X轴的夹角为β，并且人体所在场景图像中的像素位置位于场景图像的中心，则人体在坐标系中的位置(A点)与坐标原点O点之间的连线与X轴之间的夹角为β，此时，摄像头81与人体正对。人体相对于柔性显示屏80的相对位置为：人体位于柔性显示屏80的与坐标轴X的夹角为β(沿顺时针的方向上)的直线上。
请结合参阅图13和图14，当摄像头81获取的场景图像中存在人体时，若人体的像素位置处于场景图像中的中间偏右或中间偏左的位置，则表明摄像头81与用户(人体)不正对。在一幅场景图像中，处于中间位置的像素与摄像头81的光轴84的偏离 角度为零；第三获取单元34(处理器82)根据处于中间偏左位置的像素与中间像素的距离、摄像头81的广角以及场景图像的大小，可确定该像素与摄像头81的光轴84的偏离角度。第三获取单元34(处理器82)通过图像识别算法计算人体的像素位置相对场景图像的中心的像素位置，再结合摄像头81的广角以及场景图像的大小，可得到人体相对摄像头81的光轴84的偏离角度，然后根据该偏离角度、摄像头81的转动角度获取在坐标系下人体相对柔性显示屏80的相对位置。
请结合参阅图15，本实施方式中，当摄像头81获取的场景图像中存在人体时，若摄像头81转动的角度为β(其中，0≤β≤360°)，并且人体的像素位置在场景图像的中间偏左的位置，如图13所示，则人体与坐标原点的连线与X轴的夹角为摄像头81的转动角度β与该人体的像素位置相对摄像头81的光轴84的偏离角度θ的差值，人体位于柔性显示屏80的与坐标轴X的夹角为β-θ(沿顺时针的方向上)所对应的直线上。当摄像头81获取的场景图像中存在人体时，若摄像头81转动的角度为β(其中，0≤β≤360°)，并且人体的像素位置在场景图像的中间偏右的位置，如图14所示，则人体与坐标原点的连线与X轴的夹角为摄像头81的转动角度β与该人体的像素位置相对摄像头81光轴84的偏离角度θ之和，人体位于柔性显示屏80的与坐标轴X的夹角为β+θ(沿顺时针的方向上)所对应的直线上。
请参阅图16，在某些实施方式中，根据相对位置控制柔性显示屏80的部分区域进行显示，包括：
S41：根据相对位置与人体的视场角获取视场角覆盖的柔性显示屏80的人体可视区域85以作为柔性显示屏80的显示区；及
S42：控制柔性显示屏80的显示区显示画面。
请结合参阅图17，在某些实施方式中，第二控制模块40包括计算单元41及第一控制单元42。S41可以由计算单元41实现，S42可以由第一控制单元42实现。也即是说，计算单元41可用于根据相对位置与人体的视场角获取视场角覆盖的柔性显示屏80的人体可视区域85以作为柔性显示屏80的显示区；第一控制单元42可用于控制柔性显示屏80的显示区显示画面。
请结合参阅图4，在某些实施方式中，S41及S42可以由处理器82实现。也即是说，处理器82可用于根据相对位置与人体的视场角获取视场角覆盖的柔性显示屏80的人体可视区域85以作为柔性显示屏80的显示区；控制柔性显示屏80的显示区显示画面。
具体地，计算单元41(处理器82)根据相对位置与人体的视场角计算人体能够看到柔性显示屏80的大小(可视区域85的大小)。第一控制单元42(处理器82)控制 柔性显示屏80显示该尺寸大小的画面，画面呈现的位置为柔性显示屏80朝向用户一侧的区域。可以理解，人体可视区域85的尺寸大小根据不同柔性显示屏80的形状计算的方式不同。其中，相对位置包括人体相对于柔性显示屏80之间的距离、在同一坐标系下，人体与坐标原点的连线和柔性显示屏80的一预设位置(如图15所示中，预设位置为柔性显示屏80与X轴的交点)与坐标原点的连线所形成的夹角。
请参阅图18，在某些实施方式中，显示设备100还包括呈圆柱体状的主体89，柔性显示屏80至少部分环绕设置在主体89的外周面上，人体可视区域85的面积为S，S＝h*l，l＝πr(180°-α)/180°，其中，h为柔性显示屏80的高度，l为人体可视区域85的弧长，α为人体的视场角。如此，人体可视区域85的尺寸大小合适，能够为用户提供良好的观看体验。
请参阅图19，在某些实施方式中，显示设备100还包括呈正五棱柱体状的主体89，柔性显示屏80设置在主体89的外周面上，人体可视区域85的面积为S，S＝h*l，l＝5a(180°-α)，其中，h为柔性显示屏80的高度，l为人体可视区域85的长度，a为显示设备100一条边的长度，α为人体的视场角。在其他实施方式中，人体可视区域85的面积还与人体相对于柔性显示屏80之间的距离有关，人体与柔性显示屏80之间的距离越远，可视区域85的面积越大。
请参阅图20，在某些实施方式中，控制方法还包括：
S50：根据场景图像检测人体是否发生移动；
S51：在人体发生移动时，控制摄像头81转动；
S52：获取摄像头81的转动信息；及
S53：根据转动信息调整柔性显示屏80进行显示的部分区域的位置。
请结合参阅图21，在某些实施方式中，显示设备100还包括检测模块50、第五控制模块51、第二获取模块52及调整模块53。S50可以由检测模块50模块实现，S51可以由第五控制膜52实现，S52可以由第二获取模块52实现，S53可以由调整模块53实现。也即是说，检测模块50可用于根据场景图像检测人体是否发生移动；第五控制膜52可用于在人体发生移动时，控制摄像头81转动；第二获取模块52可用于获取摄像头81的转动信息；调整模块53可用于根据转动信息调整柔性显示屏80进行显示的部分区域的位置。
请结合参阅图4，在某些实施方式中，S50、S51、S52及S53可以由处理器82实现。也即是说，处理器82可用于根据场景图像检测人体是否发生移动、在人体发生移动时，控制摄像头81转动、获取摄像头81的转动信息、以及根据转动信息调整柔性显示屏80进行显示的部分区域的位置。
具体地，当第一判断模块20(处理器82)判断场景图像中存在人体时，第一控制模块10(处理器82)控制摄像头81停止转动。当检测模块50(处理器82)检测到用户(人体)相对柔性显示屏80的位置发生变化或者相对柔性显示屏80的位置变化大于预定值时，则检测模块50(处理器82)确定人体发生移动。检测模块50(处理器82)还可以通过图像识别算法计算当前场景图像中人体的像素位置相对前一场景图像中人体的像素位置的变化计算得到人体移动的速度与方向。第五控制模块51可根据人体的移动速度与方向控制摄像头81作相应地转动以对用户进行锁定追踪，使得摄像头81的光轴始终正对人体，柔性显示屏80显示画面的区域也相应跟随用户进行变化。
请参阅图1和图22，在某些实施方式中，摄像头81设置在主体89的端面上，摄像头81的转轴83与主体89的轴线平行。控制方法还包括：
S60：在摄像头81转动一预设圈数后且场景图像中都不存在人体的人像，控制显示设备100进入休眠模式或控制显示设备100停止工作。
请结合参阅图23，在某些实施方式中，显示设备100还包括第三控制模块60。S60可以由第三控制模块60实现。也即是说，第三控制模块60可用于在摄像头81转动一预设圈数后且场景图像中都不存在人体的人像，控制显示设备100进入休眠模式或控制显示设备100停止工作。
请结合参阅图4，在某些实施方式中，S60可以由处理器82实现。也即是说，处理器82可用于在摄像头81转动一预设圈数后且场景图像中都不存在人体，控制显示设备100进入休眠模式或控制显示设备100停止工作。
具体地，在摄像头81循环转动预设圈数(例如三圈)后且所获取的场景图像中均不存在人体时，表明用户不在显示设备100的附近，为节省电源，第三控制模块60(处理器82)可以控制摄像头81停止转动、以及控制柔性显示屏80进入休眠模式或控制显示设备100停止工作。如此，本实施方式的控制方法有利于实现显示设备100的智能化，在用户不需要使用显示设备100时，显示设备100能够自动进入休眠模式或者停止工作，有利于节省电源电力，提高显示设备100的续航能力。
请参阅图24，在某些实施方式中，请控制方法还包括：

请结合参阅图4，在某些实施方式中，S70可以由处理器82实现。也即是说，处 理器82可用于在显示设备100处于休眠模式，并且显示设备100接收到唤醒信号时，控制显示设备100进入工作模式。
具体地，在显示设备100处于休眠模式后，当用户需要重新使用显示设备100时，可直接进行操作唤醒显示设备100，免去了显示设备100重新开机的等待时间。如此，有利于提高用户体验。
在某些实施方式中，唤醒信号包括柔性显示屏80接收到的触控操作或手势操作所产生的信号或显示设备100设定的定时信号，其中，用于感测触控操作及手势操作的传感器可以为柔性传感器。
具体地，用户可直接触碰柔性显示屏80的屏幕唤醒显示设备100，用户也可以在柔性显示屏80上施展预设的手势操作唤醒显示设备100，用户也可以通过设定定时信号以自动唤醒显示设备100，或者用户也可以通过控制与显示设备100无线连接的控制器发出唤醒信号。
