根据第一方面，在响应于界面切换的操作，获取从当前预设界面的场景图像变换为下一预设界面的场景图像的目标视频之前，包括：获取每个预设界面对应的场景图像；根据预设的每个界面切换关系以及每个预设界面对应的场景图像，生成与每个界面切换关系匹配的视频；其中，界面切换关系用于指示切换前的界面与切换后的界面之间的对应关系；响应于界面切换的操作，获取从当前预设界面的场景图像变换为下一预设界面的场景图像的目标视频，包括：响应于界面切换的操作，确定界面切换关系；根据界面切换关系，获取与界面切换关系匹配的视频作为目标视频。
这样，手机可以预先存储与每种界面切换关系匹配的目标视频，使得在检测到对应的界面切换关系时，可以快速显示目标视频，减小手机处理的功耗，缩短获取目标视频的时长，避免电子设备在显示壁纸时出现卡顿的问题。
根据第一方面，获取预设界面对应的场景图像，包括：获取预设界面对应的拍摄角度，拍摄角度包括：拍摄距离、拍摄高度和拍摄方向；获取所有图层组成的场景中的聚焦位置；指示虚拟相机聚焦于聚焦位置，并按照预设界面对应的拍摄角度对所有图层组成的场景进行拍摄，获得预设场景对应的场景图像。这样，虚拟相机在拍摄时，获取所有图层组成的场景的聚焦位置，可以突出显示目标对象，提高壁纸的显示效果。
根据第一方面，获取所有图层组成的场景中的聚焦位置，包括：获取顶层图层中的对象；检测顶层图层中的对象是否完整；若检测到顶层图层中的对象完整，则将顶层图层的对象在第一方向上等比例划分为n个拍摄区域；获取第一拍摄区域的中心位置作为聚焦位置，第一拍摄区域为在第一方向上的第一个拍摄区域或第n个拍摄区域，n为大于1的整数。这样，手机若检测到顶层图像中的对象完整，则可以将目标对象沿第一方向划分为n个区域，如n为2、3等；聚焦位置为第一个拍摄区域或第n个拍摄区域，如可以是目标对象的头部，聚焦位置处于目标对象的头部可以突出显示目标对象。
根据第一方面，该方法还包括：若检测到顶层图层中的对象不完整，则将顶层图层的对象在第一方向上等比例划分为m个拍摄区域；获取第二拍摄区域的中心位置作为聚焦位置，第二拍摄区域为在第一方向上的第一个拍摄区域或第m个拍摄区域，1<m≤n且m为整数。这样，当目标对象不完整时，对目标对象划分的个数小于目标对象完整时划分的个数，避免出现不能突出显示目标对象的问题。
根据第一方面，检测顶层图层中的对象是否完整，包括：检测顶层图层对应的图像中目标对象是否含有水平/垂直的裁剪切线；若检测到水平/垂直的裁剪切线，则确定顶层图层中的对象不完整；若未检测到水平的裁剪切线且未检测到垂直的裁剪切线，则确定顶层图层中的对象完整。这样，电子设备通过检测是否含有水平/垂直的裁剪切线可以快速确定出目标对象是否完整，检测速度快且准确。
根据第一方面，预设界面包括：锁屏界面、主屏界面、图标编辑界面；锁屏界面与第一拍摄角度匹配，主屏界面与第二拍摄角度匹配，图标编辑界面与第三拍摄角度匹配；其中，第一拍摄角度中拍摄距离大于第二拍摄角度中的拍摄距离，第三拍摄角度的拍摄距离大于第二拍摄角度的拍摄距离且小于第一拍摄角度的拍摄距离；第三拍摄角度的拍摄高度大于第二拍摄角度的拍摄高度且小于第一拍摄角度的拍摄高度；第一拍摄角度的拍摄方向、第二拍摄角度的拍摄方向以及第三拍摄角度的拍摄方向相同。这样，锁屏界面的拍摄距离最远、主屏界面的拍摄距离最近，使得当从锁屏界面切换至主屏界面时，目标视频可以呈现出由远及近的视觉效果，使得用户有拉近目标对象的视觉体验，增强壁纸的互动性。
根据第一方面，预设界面还包括：至少一个菜单界面，菜单界面为系统桌面中除主屏界面之外的界面；菜单界面与第四拍摄角度匹配；第四拍摄角度的拍摄方向与第二拍摄角度的拍摄方向不同，第四拍摄角度的拍摄高度与第二拍摄角度的拍摄高度相同，第四拍摄角度的拍摄距离与第二拍摄角度的拍摄距离相同。这样，当主屏界面切换到菜单界面时，由于拍摄方向不同，使得目标视频可以呈现不同的视角变化效果。
根据第一方面，在响应于界面切换的操作，获取从当前预设界面的场景图像变换为下一预设界面的场景图像的目标视频之前，该方法还包括：响应于用户的第二选取操作，从图库中获取每个菜单界面的背景图层对应的图像以及主屏界面的背景图层对应的图像，主屏界面的背景图层对应的图像与菜单界面的背景图层对应的图像不同。这样，用户可以为每个预设场景设置对应的背景图像，使得在界面切换时，更新背景图像，进一步提高壁纸显示的趣味性，提高壁纸与用户之间的交互性。
根据第一方面，图层包括目标图层和背景图层；目标图层至少为1层，背景图层至少为1层。这样，背景图层多有个以及目标图层有多个，可以更加灵活的编辑每个图层对应的图像，使得可以灵活组合不同图层中的对象，生成不同的场景，使得目标视频进一步符合用户的需求。
根据第一方面，在调整每个图层各自对应的图像的位置和尺寸之前，所述方法还包括：获取包含有目标对象的图层作为目标图层；根据目标对象的轮廓对目标图层对应的图像进行裁剪，获得目标图层中的目标对象；将目标图层对应的图像更新为目标图层中的目标对象。这样，电子设备对目标对象进行裁剪，可以避免目标图层对应的图像中的背景对目标对象的干扰。
根据第一方面，预设界面包括：锁屏界面、主屏界面、图标编辑界面；根据下一预设界面对应的场景图像以及当前预设界面对应的场景图像，生成目标视频，包括：若检测到当前预设界面为锁屏界面且下一预设界面为主屏界面，则获取图标编辑界面对应的场景图像；根据锁屏界面的场景图像、图标编辑界面对应的场景图像以及主屏界面的场景图像，生成从锁屏界面的场景图像逐渐变换为主屏界面的场景图像的目标视频。这样，电子设备根据多张场景图像，生成目标视频，使得目标视频可以明显呈现出动态效果。
根据第一方面，界面切换的操作包括：屏幕解锁操作、亮屏状态下的左滑/右滑操作。
根据第一方面，图像包括二维图像或三维图像。这样，三维图像可以进一步增强目标视频的动态效果，而二维图像可以是用户拍摄的图像，使得编辑壁纸更加灵活。

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清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一目标对象和第二目标对象等是用于区别不同的目标对象，而不是用于描述目标对象的特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个处理单元是指两个或两个以上的处理单元；多个系统是指两个或两个以上的系统。
在一些实施例中，带有显示屏的电子设备中通常设置有壁纸，电子设备如手机、智能手表、智能手环等。本示例中，电子设备以手机为例进行说明。手机通显示屏上显示壁纸，壁纸通常有动态壁纸和静态壁纸，动态壁纸为供应商(如主题应用)预先制作的视频。用户可以通过主题应用选择制作好的动态壁纸，即可将动态壁纸应用于界面的壁纸显示。动态壁纸虽然是动态视频，可以应用在锁屏界面、桌面和其他菜单界面。但是，用户指示手机从锁屏界面切换到桌面过程中，没有界面切换的空间效果和纵深效果，降低了壁纸与用户的互动的体验。同时，动态壁纸也不能由用户自定义，再一次降低了壁纸与用户的互动效果。
静态壁纸为二维图像，由于静态壁纸是二维图像，用户可以选择自定义的图像作为锁屏界面和桌面的壁纸，并由显示屏显示。但是，二维图像没有空间效果，导致用户与壁纸之间的互动效果弱。图1为示例性示出的静态壁纸显示的场景示意图。
如图1的1a所示，手机的桌面包括主屏界面和菜单界面，用户点击主屏界面101中的主题应用的图标102，进入主题应用界面103。如1b所示，该主题应用界面103可以包括多种不同的壁纸，如包括动态壁纸和静态壁纸，本示例中，主题应用界面103中显示有4张壁纸，可选地，该壁纸1～壁纸4均为静态壁纸。手机响应于用户选择壁纸2的操作，在手机的桌面应用该壁纸2。如图1的1c和1b所示，手机返回主屏界面，该主屏界面104的壁纸更换为壁纸2。如1c所示，用户向左滑动屏幕，从主屏界面104切换到菜单界面105，如1d所示，菜单界面105的壁纸依然为壁纸2。即随着用户的滑动操作，该静态壁纸没有变化，没有与用户的滑动操作产生互动效果，降低了用户的使用体验。
本申请实施例提供一种壁纸显示的方法，电子设备支持用户从图库中选取图像作为壁纸，并在界面切换时，壁纸呈现空间变化的效果，增强电子设备与用户互动的效果。
图2为本申请实施例示出的一种电子设备100的结构示意图。应该理解的是，图2示电子设备100仅是电子设备的一个范例，并且电子设备100可以具有比图中所示的更多的或者更少的部件，可以组合两个或多个的部件，或者可以具有不同的部件配置。图1中所示出的各种部件可以在包括一个或多个信号处理和/或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。

图3是本申请实施例的电子设备100的软件结构框图。
电子设备100的分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。在一些实施例中，将Android系统分为三层，从上至下分别为应用程序层，应用程序框架层以及内核层。可以理解的是，图3的软件结构中的层以及各层中包含的部件，并不构成对电子设备100的具体限定。在本申请另一些实施例中，电子设备100可以包括比图示更多或更少的层，以及每个层中可以包括更多或更少的部件，本申请不做限定。
如图3所示，应用程序层可以包括一系列应用程序包。应用程序包可以包括壁纸应用，WLAN，蓝牙，音乐，游戏，短信息，图库，通话，导航等应用程序。壁纸应用可以调用图库的接口，以读取图库中的图片，该壁纸应用也可以调用照相机，获取照相机拍摄的图像。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
如图3所示，应用程序框架层可以包括窗口管理器，资源管理器，内容提供器，视图系统，电话管理器，通知管理器等。
窗口管理器用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏，锁定屏幕，截取屏幕等。
资源管理器为应用程序提供各种资源，比如本地化字符串，图标，图片，布局文件，视频文件等等。
内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。

电话管理器用于提供电子设备100的通信功能。例如通话状态的管理(包括接通，挂断等)。
通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于告知下载完成，消息提醒等。通知管理器还可以是以图表或者滚动条文本形式出现在系统顶部状态栏的通知，例如后台运行的应用程序的通知，还可以是以对话窗口形式出现在屏幕上的通知。例如在状态栏提示文本信息，发出提示音，电子设备振动，指示灯闪烁等。
内核层是硬件和软件之间的层。内核层至少包含显示驱动，摄像头驱动，音频驱动，传感器驱动。
可以理解的是，图3示出的软件结构中的层以及各层中包含的部件，并不构成对电子设备100的具体限定。在本申请另一些实施例中，电子设备100可以包括比图示更多或更少的层，以及每个层中可以包括更多或更少的部件，本申请不做限定。
图4为示例性示出的一种壁纸显示的流程图。本示例中，电子设备以手机为例进行说明，该壁纸显示的方法包括如下步骤：
步骤401：手机响应于用户的第一选取操作，从图库中获取每个图层各自对应的图像，其中，每个图层对应的图像不同。
示例性地，手机响应于用户启动主题应用的操作(如，点击主题应用的图标)，启动主题应用。该主题应用可以响应于用户的第一选取操作，获取不同图层各自对应的图像，每个图层对应的图像不同。本示例中的图层用于制作壁纸，即壁纸包括多个图层。
可选地，壁纸的图层至少包括2层，包括目标图层和背景图层。目标图层含有目标对象，目标对象可以是人物、动物(如：猫、狗、鸵鸟等)或者景物(如：桥、山、雕像等)。背景图层中的图像作为目标对象的背景。该背景图层中的图像可以包括任一对象，如背景图像中可以包括：山、水、人物等。
可选地，目标图层包括至少一层(如2层或2层以上)，背景图层包括至少一层(如2层或2层以上)。本示例中，以目标图层为1层，且背景图层为一层为例。
可选地，用户从图库中为目标图层和背景图层选择对应的图像，用户可以通过直接拍照的方式为目标图层和背景图层选择对应的图像。例如，手机响应于用户的拍摄操作，拍摄图像，并将拍摄的图像作为目标图层对应的图像或者背景图层对应的图像。
图5为示例性示出的手机获取目标图层和背景图层的场景示意图。
如图5的5a所示，在主屏界面501中显示有主题应用的图标502。用户点击该主题应用的图标502，响应于用户点击主题应用的图标502的操作，启动主题应用。该主题应用界面503包括控件504和控件505，控件504用于触发选择背景图层的图像，该控件505用于触发目标图层(如本示例中的人物图层)对应的图像。如5b所示，用户点击控件504，该手机响应于用户的点击操作，可以显示图片来源，如“从图库中选择”或“通过拍摄获取”。本示例中，以用户选择以从图库中选择为例，该主题应用可以调用图库中的图像，如图5的5c所示，该显示屏显示该背景图像选取界面506，该背景图像选取界面506中包括可选择的背景图像1～背景图像4，用户点击图像507，在图像507下方标记选中，该主题应用将该图像507作为背景图层对应的图像。同理，如图5的5b所示，用户选择控件505，跳转至人物图像选取界面508，响应于用户选中图像509的操作，该主题应用将图像509作为人物图层对应的图像。
本示例中，当手机检测到用户启动本申请中的主题应用时，可以执行步骤401。
步骤402：手机调整每个图层各自对应的图像的位置和尺寸。
示例性地，手机在获取到每个图层各自对应的图像之后，该手机可以识别目标图层(如人物图层)中的目标对象。手机根据目标对象的轮廓对目标图层对应的图像进行裁剪，获得目标图层中的目标对象；将目标图层对应的图像更新为目标图层中的目标对象。可选地，手机可以采用图像识别技术进行图像识别，识别出该图像中的目标对象。例如，手机可以识别出人脸、动物脸，进而将图像中的人物或动物作为目标对象。
图6为示例性示出的一种调整各图层对应的图像的位置和尺寸的示意图。
如图6所示，手机获取到背景图像507和人物图像509。该手机通过图像识别技术识别出该目标对象为人物，手机可以获取人物图像509中人物的轮廓，根据该人物的轮廓对图像509进行裁剪，获得该目标对象510。手机根据目标对象的轮廓，可以裁剪得到独立的目标对象，避免图像509中的背景(如图像509中的大门)对目标对象造成影响。手机将人物图层对应的图像更新为该目标对象的图像(也即该目标对象)。
手机根据各个图层所在位置，放置对应的图像。可选地，背景图层位于目标图层之下，故手机将背景图层对应的图像507放置在目标对象510之下，该背景图像507和目标对象组成待拍摄场景。如图7所示，图7中示出了背景图层和人物图层之间的位置关系，该背景图层位于人物图层之下，该桌面图标层位于人物图层至上，从而使得显示屏显示时桌面图标层不会被其他图层中的图像遮挡，同理，背景图层放置在人物图层之下，可以避免目标对象被背景图层中的图像遮挡，影响显示效果。需要说明的是，桌面图标层不属于壁纸中的图层。
该手机可以在调整界面511显示该背景图像507和目标对象组成的场景，用户可以通过拖动目标对象，手机响应于用户的拖动操作，改变目标对象的位置，同理，用户也可以拖动背景图像，手机响应于用户的拖动操作，改变背景图像的位置。可选地，手机还可以响应于用户的尺寸调整操作，改变背景图像或目标对象的尺寸(大小)。
在一个示例中，如图6所示，手机的显示屏中可以显示有与显示屏对应的边框512，该边框512用于显示屏的大小。手机还显示有边框513，边框513用于指示目标对象在显示屏的大小，该边框513可以理解为目标对象的尺寸，该边框512可以理解为显示屏的尺寸，其中，该显示屏的尺寸不能进行改变，用户可以通过拖动该边框512，确定背景图像中显示于显示屏中内容，可以通过缩小背景图像的尺寸，以增加显示于显示屏的内容，可以通过放大背景图像的尺寸，使得显示于显示屏中的内容更加清晰。本示例中，拖动边框512，响应于用户的拖动操作，确定显示于显示屏的中的背景内容，响应于用户拖动边框513的操作，确定目标对象在显示屏中的位置。
当手机调整了各图层对应图像的尺寸和位置之后，可以执行步骤403。
步骤403：手机响应于界面切换的操作，获取从当前预设界面的场景图像变换为下一预设界面的场景图像的目标视频，每个预设界面的场景图像为虚拟相机按照预设界面对应的拍摄角度对所有图层组成的场景拍摄获得。
示例性地，手机若检测到界面切换的操作，手机可以获取当前预设界面的场景图像，即切换前预设界面的场景图像，以及获取下一预设界面的场景图像。预设界面可以是锁屏界面、桌面，其中，桌面包括主屏界面和菜单界面。
界面切换的操作可以包括：用户手指上滑屏幕的操作、用户长按(如长按时长超过2秒)屏幕中的指纹感应区的操作。可选地，当手机检测到用户手指上滑操作时，可以获取目标视频，并执行步骤404，即显示目标视频。
在一个示例性中，手机可以在检测到界面切换的操作时，获取当前预设界面的场景图像和下一预设界面的场景图像。手机可以根据当前预设界面的场景图像和下一预设界面的场景图像，生成从当前预设界面的场景图像变换为下一预设界面的场景图像的目标视频，视频生成的过程可以参照现有的方式，此处将不再进行赘述。
可选地，手机在生成目标视频之前，还可以获取多张介于当前界面的场景图像和下一预设界面的场景图像之间的图像，按照预设的顺序，生成目标视频，从而使得目标视频反映出从当前预设界面的场景图像逐渐变换为下一预设界面的场景图像。
在另一个示例中，手机在调整了各个图层对应的图像的位置和尺寸之后，可以预先获取到每个预设界面的场景图像。手机根据预设的每个界面切换关系以及每个预设界面对应的场景图像，生成与每个界面切换关系匹配的视频；其中，界面切换关系用于指示切换前的界面与切换后的界面之间的对应关系。可选地，预设界面可以包括：主屏界面、锁屏界面、图标编辑界面、各菜单界面。图标编辑界面用于为用户提供对应用程序的图标编辑功能。用户可以对主屏界面进行长按操作，手机响应于用户的长按操作，显示图标编辑界面，在该图标编辑界面上，用户通过触摸图标，对应用程序的图标进行拖动，以改变应用程序的图标位置；用户还可以通过删除操作(如将图标移动至垃圾桶图标位置)，则将该图标从桌面图标界面删除该应用图标。
该预设的界面切换关系可以包括：锁屏界面切换至主屏界面的第一切换关系，锁屏界面切换至图标编辑界面的第二切换关系，主屏界面切换至锁屏界面的第三切换关系，主屏界面切换至图标编辑界面的第四切换关系，主屏界面切换至菜单界面的第五切换关系，以及相邻菜单界面(如菜单界面1切换至菜单界面2)之间的第六切换关系。
由于预先存储有各个切换关系匹配的视频，当手机检测界面切换的操作时，获取当前的界面切换关系，根据界面切换关系，从存储的视频中获取与当前界面切换关系匹配的视频作为目标视频。
下面结合附图具体介绍获取预设界面的场景图像的过程。
图8为示例性示出的背景图层和人物图层的示意图。如图8所示，背景图层为702，在背景图层702上放置有背景507，人物图层701位于背景图层702之上，该人物图层上设置有目标对象510。当手机调整了背景图像和目标对象的位置和尺寸之后，可以获取不同预设界面的场景图像。可选地，手机可以通过调用虚拟相机拍摄不同预设场景下的场景图像。
当确定了各图层对应的图像的尺寸和位置后，虚拟相机可以获取每个预设界面对应的拍摄角度。拍摄角度包括：拍摄高度、拍摄方向和拍摄距离。手机获取所有图层组成的场景的聚焦位置，指示虚拟相机聚焦于该聚焦位置，并按照预设界面对应的拍摄角度对所有图层组成的场景进行拍摄，获得每个预设场景对应的场景图像。
可选地，锁屏界面与第一拍摄角度匹配，主屏界面与第二拍摄角度匹配，图标编辑界面与第三拍摄角度匹配；其中，第一拍摄角度中拍摄距离大于第二拍摄角度中的拍摄距离，第三拍摄角度的拍摄距离大于第二拍摄角度的拍摄距离且小于第一拍摄角度的拍摄距离；第三拍摄角度的拍摄高度大于第二拍摄角度的拍摄高度且小于第一拍摄角度的拍摄高度；第一拍摄角度的拍摄方向、第二拍摄角度的拍摄方向以及第三拍摄角度的拍摄方向相同。
举例来说，图9为示例性示出不同预设界面对象的拍摄参数拍摄所有图层组成的场景的示意图。
本示例中，预设界面包括锁屏界面、图标编辑界面和主屏界面。图像507为背景图层对应的图像，目标对象510为人物图层对应的图像。当确定了图像507和图像510的尺寸和位置后，虚拟相机可以获取每个预设界面对应的拍摄角度。位置A为锁屏界面对应的拍摄位置，该位置包含拍摄距离(即虚拟相机与目标对象之间的距离)、拍摄高度。其中，拍摄方向为正对该目标对象510；位置B为壁纸界面对应的拍摄位置，该位置包含拍摄距离(即虚拟相机与目标对象之间的距离)、拍摄高度。其中，拍摄方向为正对该目标对象510。位置C为壁纸界面对应的拍摄位置，该位置包含拍摄距离(即虚拟相机与目标对象之间的距离)、拍摄高度。其中，拍摄方向为正对该目标对象510。该图9中，锁屏界面的拍摄距离大于图标编辑界面对应的拍摄距离，图标编辑界面对应的拍摄距离大于主屏界面对应的拍摄距离。同时，该锁屏界面的拍摄高度大于图标编辑界面对应的拍摄高度，图标编辑界面对应的拍摄高度大于主屏界面对应的拍摄高度。
虚拟相机需要按照聚焦位置和拍摄角度对各图层组成的场景进行拍摄。本示例中，手机可以获取顶层图层中的对象；检测顶层图层中的对象是否完整；若检测到顶层图层中的对象完整，则将顶层图层的对象在第一方向上等比例划分为n个拍摄区域；获取第一拍摄区域的中心位置作为聚焦位置，第一拍摄区域为在第一方向上的第一个拍摄区域或第n个拍摄区域，n为大于1的整数。若检测到顶层图层中的对象不完整，则将顶层图层的对象在第一方向上等比例划分为m个拍摄区域；获取第二拍摄区域的中心位置作为聚焦位置，第二拍摄区域为在第一方向上的第一个拍摄区域或第m个拍摄区域，1<m≤n且m为整数。其中，第一方向可以为目标对象的长延伸的方向，例如，若目标对象为斑马，该第一方向为目标对象从头至尾的延伸方向，若目标对象为人，则该第一方向为从头到脚的延伸方向，若目标对象雕像，该第一方向为从雕像的头到脚的延伸方向。
具体地，由于顶层图层中的目标对象为拍摄的目标，手机可以通过检测顶层图层对应的图像的目标对象是否存在水平/垂直的裁剪切线，若手机检测到水平/垂直的裁剪切线，则确定顶层图层中的对象不完整，若手机未检测到水平的裁剪切线且未检测到垂直的裁剪切线，则确定顶层图层中的对象完整。该n可以为3，m可以为2。
举例来说，图10为示例性示出的两种聚焦位置的示意图。如图10所示，虚拟相机拍摄的拍摄界面，手机检测到当前顶层图层对应的目标对象1003中没有水平的裁剪切线且没有垂直的裁剪切线，则将该目标对象1003沿第一方向划分为3等份，第一方向的如10a中箭头所示的方向，选取第一拍摄区域1002作为聚焦位置。若手机检测到当前顶层图层对应的目标对象1003中存在水平的裁剪切线，则确定该目标对象不完整，则沿第一方向将目标对象划分为2个拍摄区域，选取第二拍摄区域1004作为聚焦位置。
当手机确定了聚焦位置以及拍摄角度后，按照该聚焦位置以及预设界面对应的拍摄角度，对各个图层组成的场景进行拍摄，可以获得该预设界面的场景图像。
图11为示例性示出的图10拍摄后的场景示意图，如图11所示，该锁屏界面对应的拍摄距离为第一距离，拍摄获得场景图像为11b，该11a为该11b中目标对象的尺寸的示意图。该图标编辑界面对应的场景图像为11d，该11c为该11d中目标对象的尺寸的示意图，拍摄该场景图像11d对应的拍摄距离为第三距离。桌面对应的场景图像为11f，该11e为该11f中目标对象的尺寸的示意图，拍摄该场景图像11f对应的拍摄距离为第二距离。该第一距离大于第三距离，该第三距离大于第二距离。从图11中可知，随着拍摄距离的缩小，目标对象的尺寸逐渐变大，且在相同视角小，目标对象进入拍摄界面的部分逐渐减小。
当手机获取到各个预设界面对应的场景图像后，若确定从锁屏界面切换到桌面中的主屏界面，则手机可以获取从第一距离到第二距离拍摄的多张图像，生成从锁屏界面的场景图像逐渐变换为主屏界面的场景图像的目标视频。可选地，目标视频包含的图像越多，该目标视频的动态效果越好，可以明显表征出目标对象由远及近的动态效果。
步骤404：将目标视频作为电子设备的壁纸，并显示该壁纸。
具体地，显示该目标视频，如图12所示，锁屏界面对应的场景图像为12a，即锁屏界面的壁纸如12a所示。主屏界面对应的场景图像为12b所示，当用户处于锁屏界面时显示12a所示的壁纸。用户解锁屏幕，手机接收到界面切换的操作，获取从12a逐渐变换为12b的目标视频，如图12所示，该目标视频中还包含有图标编辑界面的场景图像。
需要说明的是，手机若检测到用户的界面切换的操作时，获取目标视频并播放目标视频。可选地，手机可以根据用户的界面切换的操作的进度，对应播放目标视频。例如，当前手机显示为锁屏界面，锁屏界面切换主屏界面的操作为用户在屏幕上上滑预设距离(如预设距离为屏幕长轴L1的一半长度)。当手机检测到用户的上滑操作时，获取目标视频，并开始播放目标视频，当用户滑到1/3L1时，用户停止上滑操作，此时手机检测到界面切换的操作未完成，停止播放目标视频。若手机检测到用户手指从当前位置返回原位置，即手机检测到从当前界面切换回锁屏界面的操作，手机可以获取从当前界面返回至锁屏界面的视频，并播放。
本示例中，手机可以根据用户的界面切换的操作的进度，控制播放目标视频，使得目标视频的播放进度可以跟随用户的界面切换的操作，例如，在显示界面显示的壁纸跟随用户手指的上滑操作进行播放，进一步提高电子设备显示的壁纸与用户的互动性。
本示例中，手机可以接收到用户自定义的各图层的图像，调整各图层中图像的位置和尺寸，手机可以自动生成各界面切换的目标视频，由于各个预设界面对应的拍摄角度不同，使得每个预设界面对应的场景图像不同，从而在不同界面切换时，目标视频可以呈现出目标对象的变化的动态视觉效果，增强了用户与壁纸之间的交互效果。
在一些实施例中，拍摄角度中还包括拍摄方向，用户通过滑动操作，可以从主屏界面向桌面中的菜单界面切换，手机可以获取从主屏界面的场景图像切换至菜单界面的场景图像的目标视频，并显示该目标视频，该主屏界面和菜单界面之间的场景图像的拍摄方向不同，从而使得显示的目标视频可以呈现出不同视角的变化的效果。
如图12所示，主屏界面如图12的12b所示，用户可以左滑屏幕或右滑屏幕，手机响应于用户的滑动操作，切换显示不同视角的图像，从而使得壁纸可以呈现不同的视角变化。图13为拍摄不同视角的场景图像的示意图。
如图13所示，主屏界面的拍摄方向如图13中黑色粗体所示，桌面中的菜单界面1对应的拍摄方向如图13细体实线所示，桌面中菜单界面2对应的拍摄方向如图13中虚线所示，该主屏界面与菜单界面的拍摄方向之间的角度大于0，若背景图像和目标对象为二维图像，主屏界面与其他菜单界面的拍摄方向的夹角小，如范围在0～30度。若背景图像和目标图像为三维图像，则该主屏界面与其他菜单界面的拍摄方向的夹角范围可以0～360度。
图14为图13中对应的场景图像的示意图。
如图14所示，用户对主屏界面右滑动，切换到菜单界面1对应的场景图像，若用户对主屏界面进行左滑操作，从主屏界面切换到菜单界面2对应的场景图像。由于每个菜单界面对应的拍摄方向不同，导致拍摄到的背景图像不同，以及目标对象相对于背景图像的位置不同，如图14所示，菜单界面2、主屏界面以及菜单界面1的背景中呈现的内容有所不同，且目标对象相对位置于背景图像的位置不同。
图15示出了各个预设界面对应的拍摄距离和拍摄方向的示意图。
如图15所示，锁屏界面对应拍摄距离最远，该锁屏界面、主屏界面以及图标编辑界面对应的拍摄方向均为拍摄方向1，该锁屏界面对应的拍摄高度可以高于图标编辑界面的拍摄高度，该图标编辑界面的拍摄高度高于主屏界面对应的拍摄高度。菜单界面1、菜单界面2的拍摄距离与主屏界面的拍摄距离相同，该菜单界面1的拍摄方向为拍摄方向2，菜单界面2的拍摄方向为拍摄方向3。
本示例中，手机通过不同的拍摄视角(即拍摄方向)获得不同的场景图像，当检测到从主屏界面切换到菜单界面的操作时，手机获取从主屏界面的场景图像逐渐变换到菜单界面的场景图像的目标视频，由于主屏界面的拍摄方向与菜单界面的拍摄方向不同，使得目标视频可以呈现出拍摄左移或右移的动态视觉效果，由于左移或右移的视觉效果与用户手指的滑动的操作匹配，进一步提升了用户与壁纸显示的交互体验。
在一些实施例中，背景图层还可以多个背景层，人物图层还可以包括多个人物层，如图16所示，该背景图层包括2个背景层，分别为背景1和背景2。人物图层包括2个人物层，分别为人物1和人物2，桌面图标层位于所有图层之上。本示例中，背景图层包括多个以及人物图层包括多个，可以提高用户自定义的灵活性，可以随意组成不同的场景，增加了壁纸的趣味性。
在一些实施例中，桌面中各个界面之间的切换时，桌面各个界面的背景图像可以不同。即当桌面相邻两个切换时，不仅可以增加视角变换的效果，还可以增加切换背景图像的效果，进一步提高壁纸的趣味性和与用户的互动性。
示例性地，手机响应于用户的第二选取操作，从图库中获取每个菜单界面的背景图层对应的图像以及主屏界面的背景图层对应的图像，主屏界面的背景图层对应的图像与菜单界面的背景图层对应的图像不同。手机调整每个图层各自对应的图像的位置和尺寸；手机响应于桌面切换的操作，获取从当前预设界面的场景图像变换为下一预设界面的场景图像的目标视频。手机将目标视频作为电子设备的壁纸，并显示该壁纸。
具体地，如图5的5b所示，用户点击控件504，手机响应于用户的点击操作，调用图库中的图片并显示，如图17所示，该背景图像选取界面1701中显示有4张背景图像。用户可以通过点击图像选择图像，如图17所示，用户选择了背景图像1702(即背景图像1)、背景图像1703(即背景图像2)和背景图像1704(即背景图像4)。需要说明的是，手机可以按照背景图像的排列顺序，依次对应不同的菜单界面和主屏界面。例如，手机可以将背景图像1作为主屏界面的背景图像，将背景图像2作为菜单界面1的背景图像，将背景图像4作为菜单界面2的背景图像。
可选地，手机也可以响应于用户的操作，按照用户的指定操作，确定每个菜单界面和锁屏界面各自对应的背景图像。
图18示出了不同界面对应的场景图像。
如图18的18a所示，手机响应于用户的调整操作调整背景图像和目标对象的尺寸和位置，具体的调整过程可以参照步骤402中的相关描述，此处将不再进行赘述。虚拟相机按照第一拍摄角度拍摄后获得主屏界面的场景图像，如18b所示。背景图像1和人物图像的位置和尺寸调整之后，手机还还可以根据背景图像2和背景图像4的尺寸对人物图像进行调整。需要说明的是，人物图像的位置确定之后，该人物图像在显示屏中的位置不会更改。
手机可以根据用户的对背景图像2的调整操作，调整背景图像2的尺寸和位置，同理，手机响应于用户的操作，调整背景图像4的尺寸和位置。
当所有背景图像的尺寸和位置调整后且人物图像的位置确定之后，虚拟相机可以按照各自对应的拍摄参数对所有图层组成的场景进行拍摄，获得对应预设界面的场景图像。可选地，该主屏界面对应第三拍摄角度，菜单界面1对应第四拍摄角度，菜单界面2对应第五拍摄角度。其中，第三拍摄角度的拍摄距离、第四拍摄角度的拍摄距离以及第五拍摄角度的拍摄距离均相同，该第三拍摄角度的拍摄方向、第四拍摄角度的拍摄方向以及第五拍摄角度的拍摄方向均不同。拍摄方向可以参照图13中所示的拍摄方向，此处将不再进行赘述。
如图18所示，18c示出了背景图像2，该虚拟相机按照第四拍摄角度对背景图像2和人物图像组成的场景进行拍摄，获得如18d所示的场景图像，该场景图像(即18d)为菜单界面1对应的场景图像。18e示出了背景图像4，该虚拟相机按照第五拍摄角度对背景图像4和人物图像组成的场景进行拍摄，获得如18f所示的场景图像，该场景图像(即18f)为菜单界面2对应的场景图像。
本示例中，手机可以预先生成从主屏界面切换至菜单界面1的目标视频，以及从菜单界面1切换至菜单界面2的目标视频。目标视频生成的过程可以参照步骤403中的相关描述，此处将不再进行赘述。
图19为示例性示出的相邻界面之间切换的示意图。
如图19所示，主屏界面对应的场景图像为(1)所示，用户右滑屏幕。手机检测到用户的右滑操作，获取从主屏界面的场景图像(即图19的(1))逐渐变换为菜单界面1的场景图像(即图19的(2))的目标视频A，并显示该目标视频A。若用户在菜单界面1时，进行右滑操作，该手机检测到用户的右滑操作，获取从菜单界面1的场景图像(即图19的(2))逐渐变换为菜单界面2的场景图像(即图19的(3))的目标视频B，并显示该目标视频B。
在一些实施例中，相邻界面切换时，手机可以直接切换为下一预设界面的场景图像。该壁纸显示的方法可以包括如下步骤：
步骤2001：手机响应于用户的第二选取操作，从图库中获取每个菜单界面的背景图层对应的图像以及主屏界面的背景图层对应的图像，主屏界面的背景图层对应的图像与菜单界面的背景图层对应的图像不同，菜单界面和主屏界面均属于桌面。
该步骤可以参照图17中相关描述，此处将不再进行赘述。
步骤2002：手机调整每个图层各自对应的图像的位置和尺寸。
步骤2003：手机响应于桌面切换的操作，获取下一待显示界面的场景图像，下一待显示界面的场景图像为虚拟相机按照下一待显示界面对应的拍摄角度对所有图层组成的场景拍摄后获得，桌面切换的操作用于指示相邻桌面之间的切换。
具体地，可以参照图18中的相关描述获取下一预设界面的场景图像。可选地，主屏界面、菜单界面1和菜单界面2均采用相同的拍摄角度(如第一拍摄角度)。该虚拟相机按照第一拍摄角度对背景图像2和人物图像组成的场景进行拍摄，获得菜单界面1对应的场景图像。该虚拟相机按照第一拍摄角度对背景图像4和人物图像组成的场景进行拍摄，获得菜单界面2对应的场景图像。
步骤2004：手机显示下一待显示界面对应的场景图像。
该手机在检测到切换操作，则显示下一预设界面对应的场景图像。
本示例中，手机在检测到界面切换的操作，直接显示下一预设界面对应的场景图像，实现快速更换背景图像，使得目标对象处于不同的背景图像中，提高了壁纸的趣味性以及提高了壁纸与用户的交互性。
