具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“至少一个”是指一个或多个，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
为了下述各实施例的描述清楚简洁，首先给出相关概念或技术的简要介绍：
显著性检测(saliency detection)：通常在面对一幅图像(一个场景)时，人眼会自动地聚焦于某些引起兴趣的区域，而选择性地忽略不感兴趣的区域，这些引起人们兴趣的区域被称之为显著性区域。在计算视觉领域，通过图像处理手段来模拟这一特性的过程称作显著性检测。通俗来讲，显著性检测就是把一幅图像中最吸引人注意的部分提取出来。
目前，显著性检测的实现可以包括两种类别：第一种是通过传统的图像处理方法，第二种是通过深度学习。经过显著性检测可以得到显著性图(saliency map)。显著 性图可以为灰度图，灰度值越高的地方表示显著性越高。
示例性的，如图1所示，对图像001(图像001可以是用户拍摄的一张包括音箱且无其他杂物的图片)进行显著性检测后可以得到图像002，图像002中的区域003的灰度值较高，可以认为是显著性区域。
本申请实施例中，针对一幅壁纸来说，当壁纸中存在人脸时，感兴趣区域包括人脸所在的区域；当壁纸中不存在人脸时，感兴趣区域包括壁纸中的显著性区域。人脸所在的区域可以是基于人脸检测算法(参考下文的相关描述)得到的，显著性区域可以是基于显著性检测得到的。
有机形状(也可以称为有机形，有机图形)：通常情况下是指区别于棱角分明的形状，主要由曲线构成。示例性的，有机形状可以由贝塞尔曲线构成。
贝塞尔曲线：贝塞尔曲线的定义包括起始点、终止点(也称锚点)和中间点。贝塞尔曲线包括一阶贝塞尔曲线、二阶贝塞尔曲线和三阶贝塞尔曲线等等。其中，三阶贝塞尔曲线包括两个相互分离的中间点，当滑动两个中间点时，三阶贝塞尔曲线的形状会发生变化。
羽化处理：原理是令选区(即被选中的区域)内外衔接部分虚化，起到渐变的作用，从而达到自然衔接的效果。羽化值越大，虚化范围越宽，衔接效果越自然。
目前，可以为系统预置的壁纸设计AOD的显示内容(例如可以根据壁纸人为设计AOD的显示内容，将人为设计的AOD的显示内容标记起来作为最终要显示的内容)。但是，针对用户任意设定的壁纸，难以达到类似的效果，无法满足用户的个性化需求。
本申请实施例提供一种灭屏显示方法，电子设备可以检测用户设置的壁纸中的感兴趣区域，感兴趣区域位于壁纸中的第一位置；电子设备根据感兴趣区域确定灭屏显示AOD图案，当电子设备处于灭屏状态时，在显示屏的第二位置显示AOD图案。这样，可以根据用户设定的任意桌面壁纸或者锁屏壁纸确定AOD的显示内容，能够满足用户的个性化需求，提高用户体验。并且，当用户点亮电子设备的显示屏(从灭屏界面进入解锁界面或桌面)时，电子设备可以显示AOD图案从预设位置(第二位置)转移到第三位置(根据感兴趣区域在锁屏壁纸或桌面壁纸中的位置确定的)，再扩散亮起壁纸的动画。这种AOD图案与壁纸形成动画的效果可以让用户产生更好的体验。

为了便于理解，以电子设备为手机为例，结合附图对本申请实施例提供的灭屏显示方法进行具体介绍。
如图3A中的(a)所示，手机检测到用户在手机A的主界面301点击设置应用302的操作后，可以显示如图3A中的(b)所示的设置界面303。在设置界面303中，可以包括多个设置选项，例如可以包括个人账号设置项(例如，Glen Gao)、WLAN设置项、蓝牙设置项、移动网络设置项、更多连接设置项、桌面和壁纸设置项等。响应于用户点击桌面和壁纸设置项对应的区域304，如图3A中的(c)所示，手机可以显示桌面和壁纸界面305。在桌面和壁纸界面305中，可以包括多个设置选项，例如可以包括灭屏显示(也可以称为息屏显示)、杂志锁屏、主题、壁纸、桌面设置、桌面风格、锁屏签名等。响应于用户点击壁纸选项对应的区域306的操作，如图3A中的(d)所示，手机可以显示壁纸界面307，在壁纸界面307中，可以包括本地壁纸和在线壁纸。响应于用户点击壁纸308的操作，如图3A中的(e)所示，手机可以显示界面309，在界面309中，可以包括壁纸308的原图310以及三个操作选项，分别为设为桌面壁纸选项311、设为锁屏壁纸选项312和同时选项(即同时设为桌面壁纸和锁屏壁纸)313。若用户选择同时选项313，响应于用户的操作，手机可以将壁纸310同时设为桌面壁纸和锁屏壁纸，即桌面壁纸和锁屏壁纸相同。当然，用户可以分别设置桌面壁纸和锁屏壁纸(即桌面壁纸和锁屏壁纸可以不相同)，本申请不做限定。
用户设置壁纸完毕后，如图3B中的(a)所示，可以返回界面305，响应于用户点击灭屏显示对应的区域320的操作，如图3B中的(b)所示，手机可以显示灭屏显示界面321。其中，提示动画/提示图片322可以用于向用户演示灭屏显示的效果。灭屏显示对应的按钮323a用于供用户选择是否开启灭屏显示功能。用户可以在阅读提示文字323b后可以了解灭屏显示的功能，并决定是否打开开关323a。若用户打开开关323a，表示用户同意开启灭屏显示的功能。这样，手机A灭屏后可以显示桌面图案或锁屏图案、时间等信息。可选的，手机还可以显示短信提醒、应用程序的消息提醒，电量等信息。
进一步的，用户可以自行选择在灭屏时显示桌面图案(即根据桌面壁纸确定AOD图案，并最终在灭屏时显示AOD图案)还是锁屏图案(即根据锁屏壁纸确定AOD图案，并最终在灭屏时显示AOD图案)。AOD图案可以参考下文的相关描述。用户可以点击按钮324，选择显示桌面图案，或者，用户可以点击按钮325，选择显示锁屏图案。当锁屏壁纸和桌面壁纸相同时，用户选择显示桌面图案或锁屏图案的效果是相同的；当锁屏壁纸和桌面壁纸不相同时，用户选择显示桌面图案或锁屏图案的效果是不同的。 通常用户不可以同时选择显示桌面图案和锁屏图案，当用户选中其中一种显示方式时，另一种显示方式对应的按钮可以置灰(即不可用)。用户也可以设置灭屏显示的时长，例如，可以通过按钮326选择全天显示(即一天的任意时段灭屏都进行灭屏显示)，或者，用户可以自行决定灭屏显示的开始时间和结束时间，用户可以通过时间控件327和时间控件328调整灭屏显示的开始时间(例如，7:00开始)和结束时间(例如，22:00结束)。用户还可以自行选择灭屏显示时的时钟样式。
如图3C中的(a)所示，响应于用户在界面321中点击时钟样式对应的区域329的操作，如图3C中的(b)所示，手机可以显示界面330，在界面330中，可以包括时钟显示样式331和时钟显示样式332。时钟显示样式331采用单排显示时间(时间显示为一行/一排)的方式，时钟显示样式332采用双排显示时间(时间显示为两行/两排)的方式。例如，响应于用户选择时钟显示样式331以及点击完成按钮333的操作，手机可以以用户选择的时钟显示样式显示时钟(时间)。可选的，时钟显示样式331可以是手机默认的显示样式。当然，手机可以提供更多其他时钟显示样式，本申请不做限定。
在一些实施例中，当锁屏壁纸和桌面壁纸不相同时，若用户选择在灭屏时显示桌面图案，那么手机灭屏时显示的AOD图案可以是根据桌面壁纸的感兴趣区域确定的。需要说明的是，本申请实施例中，手机显示的AOD图案是根据用户设置的壁纸中的感兴趣区域确定的，而非提前设计好的(例如，由设计师人工设定)，对于用户设置的任意壁纸，可以智能显示AOD图案，能够更好地满足用户的个性化需求。
下面对用户选择在灭屏时显示桌面图案的不同情况进行说明：
(1)、当用户从息屏状态进入桌面时，AOD图案和桌面壁纸可以呈现连续的动画效果。
示例性的，如图4A中的(a)所示，当手机灭屏(息屏)静置(例如，放置在办公桌上)时，手机可以进行AOD，即显示灭屏界面340。在灭屏界面340的显示区域343内可以显示AOD的显示内容，AOD的显示内容可以包括时间控件(下文称为时间)341和从桌面壁纸提取的图案(下文简称为AOD图案)342。其中，AOD图案342可以是经过显著性检测后从桌面壁纸截取的(显著性检测的过程参见下文的相关描述)，AOD图案342的边缘是一种有机形状(有机形状的计算过程参见下文的相关描述)。若手机设置了指纹识别，当手机的传感器检测到用户拿起手机、触碰手机或靠近手机时，如图4A中的(b)所示，手机可以在灭屏界面340中显示指纹图案344，响应于用户输入指纹的操作，如图4A中的(c)所示，时间341和AOD图案342可以从显示区域343(显示屏的中间位置)转移到显示区域345(显示屏的右下方)中的特定位置。可选的，时间341在移动的过程中可以逐渐隐去(颜色逐渐变淡/透明)。显示区域345中的特定位置可以是AOD图案342在桌面壁纸中的原始位置。而后，如图4A中的(d)所示，手机可以扩散亮起桌面346上的壁纸，接着，如图4A中的(e)所示，手机可以显示桌面346上的其他应用图标(下文简称为图标)和/或控件(例如，时间控件)等，包括显示区域347a和显示区域347b中的各个图标和/或控件。这样，当用户解锁手机时，手机可以显示AOD图案从中间位置回到原始位置(AOD图案在桌面壁纸中的位置)，再扩散亮起桌面壁纸，接着出现桌面上的其他图标和/或控件的快速动画。 这种AOD图案与桌面的内容形成动画的效果可以让用户产生更好的体验。并且，由于AOD图案是从用户自行设置的壁纸中提取的，可以满足用户的个性化需求。
可选的，如图4A中的(a)或(b)所示，灭屏显示时，显示区域343内的时间341和AOD图案342可以较为暗淡，避免太过刺眼导致用户的用眼不适。当用户输入指纹解锁时，如图4A中的(c)所示至(d)所示，AOD图案342可以逐渐变亮，逐渐升高与桌面相同的亮度，可以提高用户的用眼舒适度，提高用户体验。
在一种可能的设计中，对于不同的桌面壁纸，由于显著性区域的内容和位置不同，因此AOD的显示内容以及解锁时的动画效果也可以不同。例如，如图3A中的(d)所示，若用户将壁纸360设置为桌面壁纸，如图4B中的(a)所示，AOD的显示内容可以包括时间控件372a和从桌面壁纸(壁纸360对应的壁纸)提取的AOD图案372b。其中，AOD图案372b可以是经过显著性检测后从桌面壁纸(壁纸360对应的壁纸)截取的，AOD图案372b的边缘可以是经过异形边缘拟合得到的(异形边缘拟合的计算过程参见下文的相关描述)。当手机的传感器检测到用户拿起手机、触碰手机或靠近手机时，如图4B中的(b)所示，手机可以在灭屏界面340中显示指纹图案344，响应于用户输入指纹的操作，如图4B中的(c)所示，时间372a和AOD图案372b可以从显示区域343(显示屏的中间位置)转移到显示区域373a(显示屏的下方)中的特定位置，显示区域373a中的特定位置可以是AOD图案372b在桌面壁纸中的原始位置。而后，如图4B中的(d)所示，手机可以扩散亮起桌面346上的壁纸，接着，如图4B中的(e)所示，手机可以显示桌面346上的其他图标和/或控件，包括显示区域347a和显示区域347b中的各个图标和/或控件。
可选的，如图4B中的(a)或(b)所示，灭屏显示时，显示区域343内的时间372a和AOD图案372b可以较为暗淡，避免太过刺眼导致用户的用眼不适。当用户输入指纹解锁时，如图4B中的(c)所示至(d)所示，AOD图案372b可以逐渐变亮，逐渐升高与桌面相同的亮度，可以提高用户的用眼舒适度，提高用户体验。
在一种可能的设计中，如果桌面壁纸的显著性区域较大，可以对桌面壁纸的显著性区域进行整体缩小后生成AOD图案。例如，如图3A中的(d)所示，若用户将壁纸361设置为桌面壁纸，如图4C中的(a)所示，AOD的显示内容可以包括时间控件374a和从桌面壁纸(壁纸361对应的壁纸)提取的AOD图案374b。其中，AOD图案374b可以是经过显著性检测后从桌面壁纸(壁纸361对应的壁纸)截取的包含显著性区域的截图且经过缩小处理的图案。当手机的传感器检测到用户拿起手机、触碰手机或靠近手机时，如图4C中的(b)所示，手机可以在灭屏界面340中显示指纹图案344，响应于用户输入指纹的操作，如图4C中的(c)所示，AOD图案374b可以在显示区域375内扩大(放大)到原始大小，得到AOD图案374c，再将放大后的AOD图案374c移动至桌面壁纸中的原始位置。而后，如图4C中的(d)所示，手机可以扩散亮起桌面346上的壁纸，接着，如图4C中的(e)所示，手机可以显示桌面346上的其他图标和/或控件，包括显示区域347a和显示区域347b中的各个图标和/或控件。
可选的，如图4C中的(a)或(b)所示，灭屏显示时，显示区域343内的时间374a和AOD图案374b可以较为暗淡，避免太过刺眼导致用户的用眼不适。当用户输入指纹解锁时，如图4C中的(c)所示至(d)所示，AOD图案374c可以逐渐变亮， 逐渐升高与桌面相同的亮度，可以提高用户的用眼舒适度，提高用户体验。
可选的，响应于用户输入指纹的操作，可以先移动AOD图案374b至桌面壁纸中的原始位置附近，再放大得到AOD图案374c。或者，响应于用户输入指纹的操作，可以在移动AOD图案374b的过程中，逐渐放大AOD图案374b至原始大小(即在桌面壁纸中的大小)，本申请不做限定。
又例如，如图3A中的(d)所示，若用户将壁纸362设置为桌面壁纸，如图4D中的(a)所示，AOD的显示内容可以包括时间控件377a和从桌面壁纸(壁纸360对应的壁纸)提取的AOD图案377b。其中，AOD图案377b可以是经过人脸检测后从桌面壁纸截取的包含人脸的截图，AOD图案377b的边缘可以是一个有机形状。当手机的传感器检测到用户拿起手机、触碰手机或靠近手机时，如图4D中的(b)所示，手机可以在灭屏界面340中显示指纹图案344，响应于用户输入指纹的操作，如图4D中的(c)所示，时间377a和AOD图案377b可以从显示区域343(显示屏的中间位置)转移到显示区域378(显示屏的下方)中的特定位置，显示区域378中的特定位置可以是AOD图案377b在桌面壁纸中的原始位置。而后，如图4D中的(d)所示，手机可以扩散亮起桌面346上的壁纸，接着，如图4D中的(e)所示，手机可以显示桌面346上的其他图标和/或控件，包括显示区域347a和显示区域347b中的各个图标和/或控件。
可选的，如图4D中的(a)或(b)所示，灭屏显示时，显示区域343内的时间377a和AOD图案377b可以较为暗淡，避免太过刺眼导致用户的用眼不适。当用户输入指纹解锁时，如图4D中的(c)所示至(d)所示，AOD图案377b可以逐渐变亮，逐渐升高与桌面相同的亮度，可以提高用户的用眼舒适度，提高用户体验。
在一些实施例中，手机的解锁方式(即从息屏状态进入桌面或应用界面的方式)也可以是人脸识别解锁或滑动解锁或输入密码解锁，本申请不做限定。无论采用哪种解锁方式，手机解锁后，可以显示AOD图案从中间位置回到原始位置(AOD图案在桌面壁纸中的位置)，再扩散亮起桌面壁纸，接着出现桌面上的其他图标/或控件的快速动画。这种AOD图案与桌面的内容形成动画的效果可以让用户产生更好的体验。并且，由于AOD图案是从用户自行设置的壁纸中提取的，可以满足用户的个性化需求。
可选的，桌面上的其他图标和/或控件可以采用飞入的方式进入桌面，或者可以采用从淡至深直至正常显示的方式显示出来，或者，或者可以以其他动画效果显示出来，本申请不做限定。这样，可以呈现给用户更丰富的视觉体验。
在一些实施例中，手机可以显示相应的AOD图案从中间位置回到原始位置，桌面壁纸和桌面上的其他图标及控件可以同时显示出来，这样，可以减少用户的等待时间，提高用户体验。
在一些实施例中，AOD图案可以立即消失，然后迅速亮起锁屏壁纸并出现锁屏界面的其他信息，可以节省用户的等待时间，提高用户体验。
(2)、当用户从息屏状态进入锁屏界面时，AOD图案和锁屏壁纸之间可以参考现有技术中的呈现方式，即当用户点击电源键进入锁屏界面时，AOD图案可以立即消失，然后手机显示锁屏壁纸以及锁屏界面的图标和/或控件等信息。
可选的，AOD图案可以逐渐变淡消失；或者可以逐渐缩小为一个点后消失；或者可以放大后消失；例如，可以将AOD图案放大后再分解为雪花状、流星状，爱心状后 消失，或者以其他动画效果消失，本申请不做限定。这样，可以呈现给用户更丰富的视觉体验。
(3)、当用户从息屏状态进入锁屏界面后，再进入桌面时，AOD图案和锁屏界面的互动可以参考上述情况(2)中的相关描述，锁屏界面和桌面的互动(即从锁屏界面进入桌面时的显示效果)可以参考现有技术中的呈现方式，例如当用户在锁屏界面输入指纹后，锁屏壁纸和锁屏界面的图标和时间等信息可以立即消失，然后手机显示桌面壁纸以及桌面的图标和控件等。
可选的，从锁屏界面进入桌面时，锁屏壁纸和锁屏界面的图标等信息可以逐渐变淡消失；或者可以逐渐缩小为一个点后消失；或者可以放大后消失；或者可以将锁屏壁纸和锁屏界面的图标等信息分解为雪花状、流星状，爱心状后消失，或者以其他动画效果消失，本申请不做限定。这样，可以呈现给用户更丰富的视觉体验。
在一些实施例中，当锁屏壁纸和桌面壁纸不相同时，若用户选择在灭屏时显示锁屏图案，那么手机灭屏时显示的AOD图案可以是根据锁屏壁纸的感兴趣区域确定的。下面对用户选择在灭屏时显示锁屏图案的不同情况进行说明：
(1)、当用户从息屏状态进入桌面时，AOD图案和桌面壁纸之间可以参考现有技术中的呈现方式，例如当用户点击电源键进入锁屏界面时，AOD图案可以立即消失，然后手机显示桌面壁纸以及锁屏界面的图标和控件等。
可选的，AOD图案可以逐渐变淡消失；或者可以逐渐缩小为一个点后消失；或者可以放大后消失；例如，可以将AOD图案放大后再分解为雪花状、流星状，爱心状后消失，或者以其他动画效果消失，本申请不做限定。这样，可以呈现给用户更丰富的视觉体验。
(2)、当用户从息屏状态进入锁屏界面时，AOD图案和锁屏壁纸可以呈现连续的动画效果。
示例性的，如图5所示，当手机灭屏(息屏)静置(例如，放置在办公桌上)时，手机可以进行AOD，即显示灭屏界面340。在灭屏界面340的显示区域343内可以显示AOD的显示内容，AOD的显示内容可以包括时间341和从锁屏壁纸提取的AOD图案342。若手机设置了指纹识别，当手机的传感器检测到用户拿起手机、触碰手机或靠近手机时，如图5中的(b)所示，手机可以在灭屏界面340中显示指纹图案344，响应于用户按压电源键(解锁键)348的操作，如图5中的(c)所示，时间341和AOD图案342可以从显示区域343(显示屏的中间位置)转移到显示区域345中的特定位置，显示区域345中的特定位置可以是AOD图案342在锁屏壁纸中的原始位置。而后，如图5中的(d)所示，手机可以扩散亮起锁屏界面350上的壁纸，接着，如图5中的(e)所示，手机可以显示锁屏界面350上的其他信息，例如显示区域349中的信息(包括时间、信号、电量等信息)。这样，当用户点亮手机(从灭屏界面进入解锁界面)时，手机可以显示AOD图案从中间位置回到原始位置(AOD图案在锁屏壁纸中的位置)，再扩散亮起锁屏壁纸，再出现锁屏界面的其他信息的快速动画。这种AOD图案与锁屏的内容形成动画的效果可以让用户产生更好的体验。
可选的，进入锁屏界面的方式也可以是靠近手机、触摸手机(例如，双击手机)等，本申请不做限定。无论采用哪种进入锁屏界面的方式，手机都可以显示AOD图案 从中间位置回到原始位置(AOD图案在锁屏壁纸中的位置)，再扩散亮起锁屏壁纸，再出现锁屏界面的其他信息的快速动画。这种AOD图案与锁屏的内容形成动画的效果可以让用户产生更好的体验。
可以理解的是，当锁屏壁纸为上文所述的壁纸360，壁纸361、壁纸362或者其他壁纸时，AOD图案可以是根据相应的壁纸确定的，即不同壁纸对应的AOD图案不同，具体的AOD图案可以参考上文的相关描述，在此不做赘述。当用户点亮手机(从灭屏界面进入解锁界面)时，手机可以显示相应的AOD图案从中间位置回到原始位置(AOD图案在锁屏壁纸中的位置)，再扩散亮起锁屏壁纸，再出现锁屏界面的其他信息的快速动画。这种AOD图案与锁屏的内容形成动画的效果可以让用户产生更好的体验。
可选的，锁屏界面上的其他图标和/或控件可以采用飞入的方式进入锁屏界面，或者可以采用从淡至深直至正常显示的方式显示出来，或者，或者可以以其他动画效果显示出来，本申请不做限定。这样，可以呈现给用户更丰富的视觉体验。
在一些实施例中，手机可以显示相应的AOD图案从中间位置回到原始位置，然后锁屏壁纸和锁屏界面上的其他图标及控件可以同时显示出来，这样，可以减少用户的等待时间，提高用户体验。
在一些实施例中，AOD图案可以立即消失，然后迅速亮起锁屏壁纸并出现锁屏界面的其他信息，可以节省用户的等待时间，提高用户体验。
(3)、当用户从息屏状态进入锁屏界面后，再进入桌面时，AOD图案和锁屏界面的互动可以参考上述情况(2)中的相关描述，锁屏界面和桌面的互动(即从锁屏界面进入桌面时的显示效果)可以参考现有技术中的呈现方式，例如当用户在锁屏界面输入指纹后，锁屏壁纸和锁屏界面的图标和控件等可以立即消失，然后手机显示桌面壁纸以及桌面的图标和控件等。
可选的，从锁屏界面进入桌面时，锁屏壁纸和锁屏界面的图标等信息逐渐变淡消失；或者可以逐渐缩小为一个点后消失；或者可以放大后消失；或者可以将锁屏壁纸和锁屏界面的图标等信息分解为雪花状、流星状，爱心状后消失，或者以其他动画效果消失，本申请不做限定。这样，可以呈现给用户更丰富的视觉体验。
在一些实施例中，当锁屏壁纸和桌面壁纸相同时，用户选择显示桌面图案或锁屏图案的灭屏显示效果是类似的。即不论用户选择在灭屏时显示桌面图案，还是用户选择在灭屏时显示锁屏图案，AOD图案都是根据同一张图片(该图片可以既作为桌面壁纸也作为锁屏壁纸)的感兴趣区域确定的。
当锁屏壁纸和桌面壁纸相同时，用户从息屏状态进入锁屏界面时的动画效果可以参考上文的相关描述，用户从息屏状态进入桌面时的动画效果也可以参考上文的相关描述在此不做赘述。
需要说明的是，相比锁屏壁纸和桌面壁纸不同的情况，锁屏壁纸和桌面壁纸相同，用户从息屏状态进入锁屏界面后，再进入桌面的动画效果可以是更加连续的。
例如，当从锁屏界面进入桌面时，由于锁屏壁纸和桌面壁纸相同，即显示背景部分可以不变，锁屏界面上的图标等信息可以逐渐消失，桌面的图标等信息可以渐入显示区域，例如从淡至深显示出来，或者以一种动画效果显示出来，本申请不做限定。这样，用户从息屏状态进入锁屏界面后，再进入桌面的动画效果更加连续，用户体验 更高。
下面对本申请实施例提供的灭屏显示方法的具体实现方式进行说明。
当用户开启灭屏显示功能时，响应于用户的操作，如图6所示，手机可以对壁纸(桌面壁纸或锁屏壁纸)进行人脸检测。若检测到人脸，可以生成有机形状，将从壁纸提取的人脸放入有机形状中。若未检测到人脸，可以对壁纸进行显著性检测，若显著性区域满足第一条件，可以进行区域划定(裁剪)和异形边缘拟合，以得到AOD图案；若显著性区域的大小满足第二条件，可以生成有机形状，并可以将从壁纸提取的显著性区域放入有机形状中得到AOD图案。对于有机形状中的图像或异形边缘拟合的图像，可以进行羽化处理，得到AOD图案。可选的，还可以对AOD图案进行渲染处理。
进一步的，如果还需要在进行AOD时显示时间，则可以进一步确定时间控件的颜色，再对时间控件和AOD图案的组合位置进行计算，得到完整的AOD的显示内容。此时，AOD的显示内容可以包括时间控件(下文称为时间)和从壁纸提取的图案(下文简称为AOD图案)。
其中，在检测壁纸中是否存在人脸时，可以采用VJ(Viola-Jones)、多任务卷积神经网络(multi-task convolutional neural network，MTCNN)、FaceBoxes、RetinaFace、CenterFace等人脸检测算法(人脸识别算法)本申请不做限定。
当壁纸中不存在人脸(人脸检测结果为否)时，若显著性区域的大小满足第一条件，在一种可能的设计中，可以对显著性区域进行区域划定，例如可以根据显著性检测的结果对壁纸的显著性区域(也可以称为前景内容区域)进行裁剪得到AOD图案。假设显著性区域高为H，宽为W，手机的屏幕宽为w，第一条件例如可以是H大于40％w和/或W大于30％w。
示例性的，如图7A所示，可以根据不同的矩形框对不同大小的显著性区域进行裁剪。其中，矩形框701的大小为：80％w*60％w(宽*高)；矩形框702的大小为：90％w*40％w，矩形框703的大小为：50％w*80％w，矩形框704的大小为：40％w*30％w。
假设显著性区域高为H，宽为W，手机的屏幕宽为w；在W大于90％w的情况下，H大于60％w时，可以采用矩形框701对显著性区域进行裁剪，裁剪后的显著性区域的大小为80％w*60％w；H小于60％w大于40％w时，可以采用矩形框701对显著性区域进行裁剪，裁剪后的显著性区域的大小可以为80％w*H；H小于40％w大于30％w时，可以采用矩形框702对显著性区域进行裁剪，裁剪后的显著性区域的大小可以为90％w*H；H小于30％w时，可以采用矩形框704对显著性区域进行裁剪，裁剪后的显著性区域可以放入有机形状(有机形状参考下文的描述)。
在W大于80％w小于90％w的情况下，H大于60％w时，可以采用矩形框701对显著性区域进行裁剪，裁剪后的显著性区域的大小为80％w*60％w；H小于60％w大于40％w时，可以采用矩形框701对显著性区域进行裁剪，裁剪后的显著性区域的大小可以为80％w*H；H小于40％w大于30％w时，可以不对显著性区域进行裁剪，即显著性区域的大小仍为W*H；H小于30％w，可以采用矩形框704对显著性区域进行裁剪，裁剪后的显著性区域可以放入有机形状。
在W大于50％w小于80％w的情况下，H大于60％w时，可以采用矩形框701对显著性区域进行裁剪，裁剪后的显著性区域的大小为W*60％w；H小于60％w大于40％w，可 以不对显著性区域进行裁剪，即显著性区域的大小仍为W*H。
在W小于50％w大于30％w的情况下，H大于80％w时，可以采用矩形框701对显著性区域进行裁剪，裁剪后的显著性区域的大小为W*80％w；H小于80％w大于40％w，可以不对显著性区域进行裁剪，即显著性区域的大小仍为W*H。
在W小于30％w的情况下，可以采用矩形框704或矩形框703对显著性区域进行裁剪，裁剪后的显著性区域可以放入有机形状。
在另一种可能的设计中，当壁纸中不存在人脸且显著性区域的大小满足第一条件时，即显著性区域较大时，也可以对显著性区域不做裁剪，而对显著性区域进行整体缩小，得到AOD图案。或者，可以对显著性区域裁剪后再进行整体缩小，得到AOD图案。
当壁纸中不存在人脸且显著性区域的大小满足第二条件时，可以生成有机形状，并可以将显著性区域放入有机形状中，得到AOD图案。例如，假设显著性区域高为H，宽为W，手机的屏幕宽为w，第二条件可以是H小于40％w且W小于30％w。
如图7B所示，对显著性区域进行裁剪时，可以纵向做出两条三分线S1和S2，横向做出两条三分线S3和S4，得到四条三分线之间的四个交点X1、X2、X3和X4，横向(左右)选择与显著性区域(白色部分)的重心Z相反的方向(即远离重心的方向)，纵向(上下)选择与显著性区域的重心相同的方向(即靠近重心的方向)，从而选中一个三分点X2，以选中的三分点X2为中心基于矩形框C(基于上文中说明确定的矩形框)裁剪相应的区域，可以得到AOD图案。
另外，如果检测到壁纸中有两个显著性区域，可以让用户自行选择将哪个显著性区域作为AOD图案，或者手机系统可以根据预设规则确定最终作为AOD图案的显著性区域(即第一显著性区域)。再对该显著性区域(即第一显著性区域)进行处理得到AOD图案，具体过程可以参考上文的相关描述，在此不做赘述。其中，预设规则可以是根据多个显著性区域的显著性值(显著性值用于表征显著性区域的显著性高低)确定一个显著性区域。例如，确定显著性最高的一个显著性区域作为第一显著性区域。
当确定出AOD图案后，为了使得AOD图案的边缘更加平滑圆润，可以对AOD图案的边缘像素块进行异形边缘拟合，用拟合得到的曲线作为最终显示的AOD图案的边缘。
示例性的，如图8所示，可以将AOD图案的像素区块中每两个凸顶点的连线的中点设置为三次贝塞尔曲线的起点和终点，将每个凸顶点与每两个凸顶点的连线的中点之间的连线的中点(即每两个凸顶点的连线的一个四分点)作为三次贝塞尔曲线的控制点，由此形成闭合的贝塞尔曲线。
当壁纸中存在人脸(即人脸检测结果为是)时，可以将人脸所在的区域作为AOD图案。当存在多个人脸时，可以选择面积更大的人脸所在的区域作为AOD图案。并可以根据人脸所在的区域的特征(例如，人脸的朝向等)计算有机形状作为AOD图案的显示边缘，避免直接采用人脸作为AOD的显示边缘存在的用户观感诡异的风险。
或者，当壁纸中不存在人脸且显著性区域的大小满足第二条件时，可以根据显著性区域的特征(例如，显著性区域的重心等)计算有机形状，将显著性区域放入有机形状中作为AOD图案，避免直接采用显著性区域作为AOD图案导致用户观感不好的问题。
如图9中的(a)所示，以O点为圆心作半径为R的圆Y。其中，R的取值范围可以为25％w到30％w，w是手机屏幕的宽度。在圆Y的边上确定A点、B点和C点，A点与圆心O点的纵坐标(y轴坐标)一致，A点与圆心O点的连线以及B点与圆心O点的连线的夹角为120°，B点与圆心O点的连线以及C点与圆心O点的连线的夹角为120°。分别以A点和B点作为起点和终点，以切线L的端点L1和切线M的端点M1为中间点作贝塞尔曲线；并分别以B点和C点作为起点和终点，以切线M的端点M2和切线N的端点N1为中间点作贝塞尔曲线；并分别以C点和A点作为起点和终点，以切线N的端点N2和切线L的端点L2为中间点作贝塞尔曲线，由此形成由三个三阶贝塞尔曲线形成的闭合有机形状J1。其中，切线L是经过A点与圆Y相切的切线，切线L的中点为A点，A点到L1点的长度为R且A点到L2点的长度为R，即切线L的长度为2R。切线M是经过B点与圆Y相切的切线，切线M的中点为A点，B点到M1点的长度为R且B点到M2点的长度为R，即切线M的长度为2R。切线N是经过C点与圆Y相切的切线，切线N的中点为A点，C点到N1点的长度为R且C点到N2点的长度为R，即切线N的长度为2R。
进一步的，如图9中的(b)所示，可以将切线L逆时针进行一定角度的随机倾斜(倾斜角度小于20度，例如，倾斜角度可以为18度)得到切线L’，并且可以将C点与N2之间的线段的长度缩短，缩短范围在2/3R和3/4R之间，例如可以缩短为2/3R)，然后分别以A点和B点作为起点和终点，以切线L’的端点L1’和切线M的端点M1为中间点作贝塞尔曲线；并分别以B点和C点作为起点和终点，以切线M的端点M2和切线N的端点N1为中间点作贝塞尔曲线；并分别以C点和A点作为起点和终点，以切线N的端点N2和切线L’的端点L2’为中间点作贝塞尔曲线，此时可以得到有机形状J2，可以将有机形状J2作为有机形状模版。
当确定出有机形状模板后，可以按照如下方式将包含人脸的截图放置到有机形状中。其中，包含人脸的截图是从壁纸中截取的，其布局和壁纸中被截取部分的布局一致。如图10中的(a)-(d)所示，在上下(纵向)布局上，人的头顶与有机形状的顶部边缘之间距离约20％A，例如可以是18％A。其中，A表示有机形的高度。如图10中的(a)和(b)所示，对于人脸朝向为左方(左前方)的人脸，在左右(横向)布局上，人脸的位置位于有机形状的右侧的黄金比例分割线处。可以理解的是，对于人脸朝向为右方(右前方)的人脸，在左右(横向)布局上，人脸的位置位于有机形状的左侧的黄金比例分割线处。如图10中的(c)和(d)所示，对于人脸朝向为正前方的人脸，在左右(横向)布局上，人脸的位置位于有机形状的中间位置(即居中放置)。这样，包含人脸的显示区域和有机形可以更加符合美学构图，可以提高观感。
另外，当人物(人脸)的面积相较于有机形状来说过小(例如，人物的高度小于15％A，例如，为1/10A或1/15A)时，人物可以居中放置，人的头顶与有机形状的顶部边缘之间距离不限定为20％A左右。且对于过小的无人物图片(即显著性区域过小的情况)，可以将显著性区域居中放置在有机形状中。
需要说明的是，对于图案不同的壁纸(图片)，AOD图案的有机形状可以不同。对于同一个壁纸(图片)，每次灭屏时显示的AOD图案的有机形状也可以不同，这样，这样的设计不仅仅会让产品变得多样化，更增加了趣味性，使得AOD的效果更生动， 可以提高用户体验。
进一步的，可以将时间控件与AOD图案组合起来。时间控件与AOD图案可以重叠或者不重叠。当时间控件与AOD图案重叠时，时间控件与AOD图案的组合方式包括以下步骤：
(1)确定时间控件的颜色。可以根据AOD图案的取色结果进行调整得出时间控件的颜色。例如，如图11中的(a)所示，可以用虚线a和虚线b将时间控件(例如，08 08)分为三部分，其中，虚线a的上方部分的颜色可以为白色；虚线a和虚线b之间的部分的颜色可以为AOD图案的主色；虚线b的下方部分的颜色可以为AOD图案的辅色。又例如，如图11中的(b)所示，可以用虚线c和虚线d将时间控件(例如，08 08)分为三部分，其中，虚线c的上方部分的颜色可以为白色；虚线c和虚线d之间的部分的颜色可以为AOD图案的主色；虚线d的下方部分的颜色可以为AOD图案的辅色。
(2)计算时间控件与AOD图案的组合位置。首先，确定AOD图案的质心、重心(中心/几何中心)或对称中心，将时间控件放置在AOD图案的质心，重心或对称中心的相反方向，这样可以达到一种视觉的平衡。
如图12A所示，时间控件可以显示为两排。具体的，如图12A中的(a)、(b)和(d)所示，AOD图案的质心O位于右下区域，因此时间控件可以显示在AOD图案的左上区域，以达到视觉平衡；如图12A中的(c)所示，AOD图案的质心O位于左下区域，因此时间控件可以显示在AOD图案的右上区域，以达到视觉平衡。
如图12B所示，时间控件可以显示为一排。具体的，如图12A中的(a)、(b)和(d)所示，AOD图案的质心O位于右下区域，因此时间控件可以显示在AOD图案的左上区域，以达到视觉平衡；如图12A中的(c)所示，AOD图案的质心O位于左下区域，因此时间控件可以显示在AOD图案的右上区域，以达到视觉平衡。
(3)羽化边缘。可以根据AOD的显示内容的整体风格(包括时间控件的数字字体风格、AOD图案的风格等)设置预设的边缘羽化数值，使得AOD的显示内容看起来更美观。
另外，当时间控件与AOD图案不重叠时，时间控件和AOD图案可以分开显示。例如，如图13所示，时间控件341可以显示在手机屏幕的上方居中位置，AOD图案342可以显示在手机屏幕中间位置。
另外，目前手机通常采用OLED屏幕，可以控制单独的像素点发光，当屏幕显示黑色时，黑色区域不需要发光，可以大大减少耗电量。可以理解的是，AOD设计时需要规避OLED屏特有的烧屏问题，即若干个像素点长时间显示同一个颜色，导致该区域老化影响显示效果。为了更好地延长OLED的使用寿命，可以使AOD的显示内容定时的在一定范围内上下跳动或左右跳动移动位置，即在一个固定的区域内反复移动，这样既不影响视觉观感，又能够有效防止烧屏。
基于本申请实施例提供的方法，当用户点亮手机(从灭屏界面进入解锁界面或桌面)时，手机可以显示AOD图案从中间位置回到原始位置(AOD图案在锁屏壁纸或桌面壁纸中的位置)，再扩散亮起锁屏壁纸或桌面壁纸，再出现锁屏界面或桌面上的其他信息的快速动画。这种AOD图案与壁纸形成动画的效果可以让用户产生更好的体验。 并且，基于本申请实施例提供的方法，可以根据用户设定的任意桌面壁纸或者锁屏壁纸确定AOD的显示内容，能够满足用户的个性化需求，提高用户体验。
如图14所示，本申请实施例提供一种灭屏显示方法，包括：
1401、电子设备检测用户设置的壁纸中的感兴趣区域，感兴趣区域位于壁纸中的第一位置。
其中，用户设置的壁纸包括桌面壁纸或锁屏壁纸。用户设置的壁纸的来源包括电子设备拍摄得到的图片、电子设备下载的图片或电子设备的截图中的至少一种。这样，可以根据用户设定的任意桌面壁纸或者锁屏壁纸确定AOD的显示内容，能够满足用户的个性化需求，提高用户体验。
可选的，用户也可以设置桌面画报或锁屏画报，即根据预设规律切换不同的壁纸，比如可以每隔预设时间为用户推送一张图片作为桌面壁纸或锁屏壁纸。
在一些实施例中，电子设备可以对壁纸进行人脸检测；当壁纸中存在人脸时，感兴趣区域包括人脸所在的区域；当壁纸中不存在人脸时，电子设备对壁纸进行显著性检测，感兴趣区域包括壁纸中的显著性区域。
1402、电子设备根据感兴趣区域确定AOD图案。
若电子设备检测到人脸，可以生成有机形状，从壁纸中裁剪出人脸区域并放入有机形状中，以得到AOD图案；若未检测到人脸，可以对壁纸进行显著性检测得到第一显著性区域；若第一显著性区域的大小满足第一预设条件，对第一显著性区域进行裁剪，并对裁剪后的第一显著性区域进行异形边缘拟合，以得到AOD图案；若第一显著性区域的大小满足第二预设条件，生成有机形状，并将第一显著性区域放入有机形状中，以得到AOD图案。
可选的，对第一显著性区域进行裁剪包括：对第一显著性区域直接进行裁剪得到AOD图案；或者，对第一显著性区域进行裁剪以及缩小或放大处理得到AOD图案。这样，可以将AOD图案的大小控制在合理范围内，美化AOD图案的显示效果，从而提高用户观感。
可选的，对壁纸进行显著性检测得到第一显著性区域包括：当壁纸包括多个显著性区域时，将用户选择的一个显著性区域作为第一显著性区域；或者，根据预设规则确定第一显著性区域；其中，预设规则包括根据多个显著性区域中每个显著性区域的显著性高低确定第一显著性区域。
可选的，对裁剪后的第一显著性区域进行异形边缘拟合包括：基于贝塞尔曲线对裁剪后的第一显著性区域的边缘进行拟合。其中，贝塞尔曲线是一种平滑的曲线，基于贝塞尔曲线对裁剪后的第一显著性区域的边缘进行拟合可以使第一显著性区域的边缘更加平滑，从而使得AOD图案的边缘更加平滑，美化AOD图案的显示效果，提高用户观感。
可选的，若检测到人脸，生成有机形状，包括：根据人脸的特征确定有机形状，人脸的特征包括人脸的朝向；若第一显著性区域的大小满足第二预设条件，生成有机形状，包括：根据第一显著性区域的特征确定有机形状，第一显著性区域的特征包括第一显著性区域的重心、质心或对称中心所在的方向。这样，可以使得包含有机形状的AOD图案更加符合美学构图，可以提高观感。
可选的，有机形状是由贝塞尔曲线组成的。贝塞尔曲线是一种平滑的曲线，有机形状也是一种柔和的形状，根据有机形状得到的AOD图案也会使得用户观感更好。
可选的，从壁纸中裁剪出人脸区域并放入有机形状中包括：人脸的顶部与有机形状的顶部之间间隔预设距离，且人脸位于有机形状的黄金比例分割线处；或者人脸居中放置于有机形状中。这样，包含人脸的显示区域和有机形可以更加符合美学构图，可以提高观感。
可选的，可以对AOD图案的边缘进行羽化处理。这样，可以使AOD图案的边缘更加平滑，美化AOD图案的显示效果，从而可以提高用户观感。
1403、当电子设备处于灭屏状态时，在显示屏的第二位置显示AOD图案，第二位置是预设的。
可选的，执行步骤1403之前，电子设备还可以接收用户设置壁纸的操作，以及用户确定进行灭屏显示的操作。用户设置壁纸并设置进行灭屏显示后，电子设备可以根据用户设定的任意桌面壁纸或者锁屏壁纸确定AOD的显示内容，能够满足用户的个性化需求，提高用户体验。
可选的，电子设备处于灭屏状态时，电子设备还显示时间、短信提醒、未接来电提醒、应用程序的消息提醒、天气或电量中的至少一种信息。这样，可以使得灭屏时的显示内容更丰富，可以为用户提示更多的信息，防止用户错过重要信息，可以提高用户体验。
在一些实施例中，若电子设备处于灭屏状态时，电子设备还显示时间，时间的颜色是根据AOD图案的颜色确定的，且时间位于AOD图案的质心、重心或对称中心的相反方向。这样可以达到一种视觉的平衡。
可选的，AOD图案从第二位置移动至第三位置包括：时间与AOD图案同时移动，时间在移动过程中逐渐消失，或者当AOD图案移动到第三位置后时间消失。这样的设计使得产品变得多样化，增加了趣味性，使得AOD的效果更生动，可以提高用户体验。
1404、响应于用户点亮显示屏的操作，AOD图案从显示屏的第二位置移动至显示屏的第三位置，第三位置是根据感兴趣区域在壁纸中的第一位置确定的。
应该理解的是，当壁纸铺满显示屏时，第一位置可以与第三位置相同；当壁纸等比例缩小显示时，第三位置可以是参考第一位置确定的。比如，感兴趣区域位于壁纸的左下角，那么第三位置就是指显示屏的左下角。
1405、电子设备显示壁纸。
在一些实施例中，电子设备先显示壁纸，再显示壁纸对应的其他信息；当壁纸为锁屏壁纸时，壁纸对应的其他信息包括锁屏界面上的应用图标和控件；当壁纸为桌面壁纸时，壁纸对应的其他信息包括桌面上的应用图标和控件。这种先亮起壁纸，再出现壁纸对应的其他信息的快速动画可以让用户产生更好的体验。
需要说明的是，图14所述的实施例中的电子设备可以为前述实施例中的手机。图14所述的实施例中未详述的部分，可以参考前述实施例，在此不做赘述。
基于本申请实施例提供的方法，电子设备检测用户设置的壁纸中的感兴趣区域，感兴趣区域位于壁纸中的第一位置；电子设备根据感兴趣区域确定灭屏显示AOD图案，当电子设备处于灭屏状态时，在显示屏的第二位置显示AOD图案。这样，可以根据用 户设定的任意桌面壁纸或者锁屏壁纸确定AOD的显示内容，能够满足用户的个性化需求，提高用户体验。并且，当用户点亮电子设备的显示屏(从灭屏界面进入解锁界面或桌面)时，电子设备可以显示AOD图案从预设位置(第二位置)转移到第三位置(根据感兴趣区域在锁屏壁纸或桌面壁纸中的位置确定的)，再扩散亮起壁纸的动画。这种AOD图案与壁纸形成动画的效果可以让用户产生更好的体验。
