在一种实际交互场景中，终端可以通过执行步骤(a1)至步骤(a5)来替代步骤201。
步骤(a1)，响应于处于锁屏状态，在接收到实体按键操作时，点亮屏幕。
在本实施例中，终端可以在锁屏状态下直接提供壁纸的更换与生成。由于该操作相对不涉及隐私内容。因此，一种可能的方式中，该过程可以在没有解锁终端时实现。在本例中，当终端中的实体键被按压时，终端点亮自身的屏幕。在另一种可能的方式中，终端还能够被语音唤醒亮屏。
步骤(a2)，响应于在锁屏状态的接收壁纸编辑更换指令，显示模版选择界面。
可选地，终端可以在锁屏状态的用户界面中显示壁纸更换按钮，当该按钮被点击时，终端接收壁纸编辑更换指令。其中，模版选择界面中可以显示至少一种壁纸模版。

可选地，终端第一指令可以是用户从多种壁纸模版中确定出目标壁纸模版时触发的指令。其中，第一按钮可以用于确认目标壁纸模版。其既可以是具有可视图形的按钮，也可以是蒙在各个壁纸模版上，在壁纸模版被选定时自动被触发的按钮。
步骤(a4)，响应于图像选择指令，显示图像选择界面，所述图像选择界 面中包括所述目标图像。
可选的，当图像选择界面中需要显示终端拍摄的图像时，终端需要对用户的身份进行验证。
在本申请中，终端还能够按照目标壁纸模版中对应的显示元素的目标个数，确定出候选图像。比如，目标壁纸模版中对应的显示元素的目标个数是3个，则终端可以随机遍历终端中的图像或者全部遍历终端中的图像，将显示元素是3个的图像作为候选图像进行显示。可选的，终端可以将显示评分高的图像排列在候选图形的靠前次序。随后，终端在图像选择界面显示候选图像，候选图像中包括目标图像。也即，终端最终选择出的目标图像中的显示元素符合目标壁纸模型的需求。
步骤(a5)，响应于接收到第二指令，获取所述目标图像。
步骤202，根据壁纸创作指令获取目标图像以及目标壁纸模板。
目标图像由用户选择得到。可选地，目标图像为本地存储的图像，或者，从网络中下载的图像。

目标壁纸模板也由用户选择得到。可选地，终端在壁纸创作界面中显示壁纸模板列表，壁纸模板列表中被框选的壁纸模板也即是目标壁纸模板，终端在接收到对应于壁纸创作界面的指定滑动信号时，切换目标壁纸模板。上述指定滑动信号的滑动方向与壁纸模板列表中壁纸模板的排布方向相同或相反。可选地，目标壁纸模板包括至少一个显示元素。上述显示元素包括且不限于雪山、太阳、草地、鲜花、河流、大树、小鸟、狗或猫等等。
步骤203，对目标图像进行取色处理，得到至少一种颜色。
取色处理是指获取并识别出目标图像所拥有的各种颜色。比如，目标图像中包括天空、太阳、草地等显示元素，终端对目标图像进行取色处理，分别得到天空对应的蓝色、太阳对应的金色、草地对应的绿色。
可选地，终端通过预设的颜色提取算法对目标图像进行取色处理。可选地，上述预设的颜色提取算法为Palette(中文：调色板)算法。
可选地，终端在进行取色处理时，显示预设的动画效果。上述预设的动画效果由终端默认设定，或者，由用户自定义设定，本申请实施例对此不作限定。示例性地，预设的动画效果为马赛克。
结合参考图3，其示出了本申请一个实施例提供的一种显示预设的动画效果的示意图。在取色过程中，终端在目标图像的上层叠加显示马赛克。
步骤204，在至少一种颜色中确定出显示元素对应的颜色。
可选地，终端根据显示元素对应的自然色，在至少一种颜色中确定出显示元素对应的颜色。上述显示元素对应的自然色是指显示元素在自然环境所呈现的颜色。比如，玫瑰在自然环境所呈现的颜色为红色，则玫瑰的自然色为红色。

在一种可能的实现方式中，终端从服务器获取推荐信息，根据该推荐信息在显示元素对应的饱和度取值区间确定目标饱和度值，在显示元素对应的亮度取值区间确定目标亮度值。示例性地，其它终端在通过目标壁纸模板生成合成壁纸后，接收对应于合成壁纸的满意度调查，之后将上述满意度调查结果反馈至服务器，服务器对满意度调查结果进行统计，将满意度符合预设条件的合成壁纸所采用的饱和度值、亮度值携带于推荐信息，并将推荐信息发送至终端，终端将推荐信息中携带的饱和度值确定为目标饱和度值，将推荐信息中携带的亮度值确定为目标亮度值。
在另一种可能的实现方式中，终端显示该显示元素对应的饱和度调节进度条和亮度调节进度条。饱和度调节进度条的调节范围也即是该显示元素对应的饱和度取值区间，亮度调节进度条的调节范围也即是该显示元素对应的亮度取值区间。终端接收对应于饱和度调节进度条的调节信号，根据该调节信号确定目标饱和度值。终端接收对应于亮度调节进度条的调节信号，根据该调节信号确定目标亮度值。可选地，终端根据被调节的饱和度值和/或亮度值实时显示预览效果，用户在对预览效果满意时确定最终采用的目标饱和度值和目标亮度值。
在其它可能的实现方式中，终端在显示元素对应的饱和度取值区间随机确定目标饱和度值，终端在显示元素对应的亮度取值区间随机确定目标亮度值。
步骤207，根据显示元素对应的颜色、目标饱和度值、目标亮度值生成合成壁纸。
可选地，终端将各个显示元素分别对应的颜色、目标饱和度值、目标亮度值分别填充至各个显示元素，得到合成壁纸。
在本申请实施例中，将用户选择的目标图像作为壁纸生成素材，从上述目标图像中取色得到生成壁纸所需的颜色，最后将从目标图像中获得的颜色填充至目标壁纸模板中的各个显示元素，丰富壁纸的获取形式，提高用户在选择壁纸时的参与度。
综上所述，本申请实施例提供的技术方案，通过将用户选择的目标图像作为壁纸生成素材，从上述目标图像中取色得到生成壁纸所需的颜色，最后通过从目标图像中获得的颜色以及预先选择的目标壁纸模板生成合成壁纸，允许用户自定义生成合成壁纸，丰富壁纸的获取形式。

终端通过预设的颜色量化算法对各个像素点的显示参数进行处理，得到像素点对应的颜色值。上述预设的颜色量化算法为中位切分算法。
步骤404，根据目标图像中的各个像素点分别对应的颜色值确定至少一种颜色。
可选地，终端统计每种颜色值的数量，根据每种颜色值的数量确定至少一种颜色。示例性地，终端将颜色值的数量按照由大到小的顺序进行排列，之后将排序在前n位的颜色值对应的颜色确定为至少一种颜色，n根据实验或经验设定，本申请实施例对此不作限定。通过上述方式，将目标图像中较大面积的颜色筛选出来，用于后续的壁纸合成流程。
在其它可能的实现方式中，终端显示颜色值列表，该颜色值列表中包括目标图像中的所有颜色值，接收用户对颜色值列表中的目标颜色值的选择信号，将目标颜色值对应的颜色确定为至少一种颜色。目标颜色值为一种或多种。通过上述方式，实现由用户自定义选择目标图像中的颜色，用于后续的壁纸合成流程。
