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，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“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。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
构图是衡量图像质量的重要参考标准之一，目前市场上已经出现了一些能够为用户提供构图推荐的电子设备；例如，具有“拍摄建议”功能的手机。该“拍摄建议”功能主要依据专业人士提供的摄影规则，基于机器学习分析很多张高质量照片的成果，为拍摄的照片提供构图建议。参见图1A至图1D，该“拍摄建议”功能具体为：用户启动相机，在拍摄预览界面，通过图1A所示的相机设置控件10进入图1B所示的相机设置界面，相机设置界面中具有拍摄建议选项20，用户可以打开拍摄建议选项20，开启“拍摄建议”功能。参见图1C，在使用“拍摄建议”功能进行拍照时，出现圆圈101，圆圈101用于指示镜头位置，用户可以通过移动手机调整圆圈101的位置。同时，预览界面中还出现圆圈102，圆圈102是手机针对当前拍摄场景为用户提供的构图建议，圆圈102用于提示用户将手机镜头移动至圆圈102所在的位置以获得“最佳照片”。参见图1D，用户可以根据圆圈102的提示移动手机，将圆圈101的位置调整至与圆圈102的位置近似重合，当手机检测到圆圈101与圆圈102近似重合时，自动拍下照片。
可以看出，上述具有“拍摄建议”功能的手机虽然可以在相机预览中引导用户进行构图，但是该“拍摄建议”功能在使用过程中，需要通过用户操作将圆圈101的位置调整至与圆圈102的位置近似重合，显然，该过程需要用户进行精准、持续且复杂的操作才能完成，使得用户参与太多，而且将圆圈101的位置调整至与圆圈102的位置近似重合的效果可能因人而异，因此最终构图效果也会存在差异，从而用户体验较差。同时，“拍摄建议”功能需要在手机移动的过程中进行实时判断是否移动至最佳照片位置，对手机的性能要求较高。而且，用户开启“拍摄建议”功能后，手机在拍照时会对所有拍摄场景进行无差别构图，而用户可能只期望对部分感兴趣的目标场景提供构图建议，这样的无差别构图会造成手机的资源浪费。
本申请实施例提供了一种构图推荐方法，可以应用于电子设备，能够针对用户感兴趣的目标图像显示推荐图像，该推荐图像基于推荐的构图方案得到，用户选择目标推荐图像后即可获取效果较好的图像，与现有技术中在相机预览模式下的构图引导方案相比，无需用户进行精准、持续且复杂的操作，从而提高了用户体验。
此外，在本申请实施例提供的构图推荐方法中，用户选择目标推荐图像即可，而不需要进行复杂的操作，因而构图效果与推荐图像的构图方案一致，不存在不同用户的操作差异而导致构图效果差异较大的情况。
另外，在本申请实施例提供的构图推荐方法中，无需在手机移动的过程中实时判断是否移动至最佳照片位置，从而能够有效降低终端设备硬件要求。并且，该方法针对用户感兴趣的目标图像才提供构图推荐功能，避免了无差别构图造成的资源浪费。
本申请实施例提供的构图推荐方法可以应用于手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、 笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等电子设备上，本申请实施例对电子设备的具体类型不作任何限制。

存储器120用于存储执行本申请方案的应用程序代码，并由处理器110来控制执行。存储器120可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，RAM或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，通过总线与处理器相连接。存储器也可以和处理器集成在一起。

为了便于理解，本申请以下实施例将以具有图2和图3所示结构的手机为例，结合附图对本申请实施例提供的构图推荐方法进行具体阐述。
首先，手机可以显示原始图像。原始图像可以为用户感兴趣的目标图像。例如，原始图像可以为手机的摄像头拍摄的图像；或者，原始图像可以为手机从其他电子设备实时接收/预先接收的图像；或者，原始图像可以为手机中存储的图像；或者，原始图像可以为手机实时/预先从网络下载的图像等。可以理解的是，原始图像不限于上述类型，本申请实施例对原始图像的类型不作限定。
在手机可以显示原始图像后，用户可以执行指示构图推荐模式的操作。在手机检测到用户用于指示构图推荐模式的操作后，手机进入构图推荐模式。在构图推荐模式下，手机可以根据当前显示的原始图像为用户呈现推荐图像，不同的推荐图像与不同的构图方案相对应，使得用户可以从推荐图像中选择符合用户审美的目标推荐图像。
其中，用户指示构图推荐模式的方式可以有多种。
在一实施例中，用户可以在拍照后指示进入构图推荐模式。例如，图4A示出了手机的一种图形用户界面(graphical user interface，GUI)，该GUI为手机的桌面401。当手机检测到用户点击桌面401上的相机应用(application，APP)的图标402的操作后，可以启动相机应用，显示如图4B所示的另一GUI，该GUI可以称为拍摄预览界 面403。该拍摄预览界面403上可以包括取景框404。在预览状态下，该取景框404内可以实时显示预览图像。示例性的，参见图4B，拍摄预览界面403上还可以包括拍摄控件405。在拍照模式下，当手机检测到用户点击该拍摄控件405的操作后，手机执行拍照操作。之后，手机可以在拍摄预览界面403的下方显示所拍摄的图像的缩略图406。当手机检测到用户点击该缩略图406的操作后，显示如图4C所示的另一GUI，该GUI可以称为图像展示界面407。该图像展示界面407可以包括所拍摄的图像1。图像1也可以称为原始图像。
在一些实现方式中，图像展示界面上包括用于指示构图推荐模式的控件，当手机检测到用户点击该控件的操作时，手机进入构图推荐模式。示例性的，该控件可以为图5A所示的控件501，或者图5B所示的控件502。
在另一些实现方式中，参见图4C，图像展示界面上包括编辑控件408。在手机检测到用户点击编辑控件408后，参见图6，手机显示功能列表601，该功能列表601包括用于指示构图推荐模式的控件602、用于指示滤镜的控件以及用于指示调整的控件等。在手机检测到用户点击控件602后，手机进入构图推荐模式。
在另一些实现方式中，参见图7A，图像展示界面上包括魔法棒控件701，在手机检测到用户点击魔法棒控件701后，参见图7B，手机显示处理模式界面702。在手机检测到用户点击处理模式界面上用于指示构图推荐模式的控件703后，手机进入构图推荐模式。
在另一些实现方式中，手机在图像展示界面上检测到用户的预设手势后，进入构图推荐模式。例如，参见图8A，手机检测到用户在图像展示界面上划了一个圆圈轨迹的手势操作后，进入构图推荐模式。再例如，手机检测到用户在图像展示界面的图像上的长按操作后，进入构图推荐模式。再例如，手机检测到用户在图像展示界面的图像上的压力按操作(按压的力度大于或者等于预设值)后，进入构图推荐模式。
在另一些实现方式中，在手机拍照后，手机可以自动进入构图推荐模式。
在另一些实现方式中，在手机显示图像展示界面后，参见图8B，若手机检测到用户语音指示进入构图推荐模式或使用构图推荐功能的操作，则进入构图推荐模式。
在另一实施例中，用户可以在图库中指示构图推荐模式。例如，图9A示出了手机的一种GUI，该GUI为手机的桌面901。当手机检测到用户点击桌面901上的图库应用的图标902的操作后，可以启动图库应用，显示如图9B所示的另一GUI，该GUI可以称为图库界面，图库界面可以包括多个图像的缩略图。当手机检测到用户点击缩略图903后，可以显示图9C所示的另一GUI，该GUI可以称为图像展示界面904。其中，图像展示界面904可以与图4所示的图像展示界面407相同。该图像展示界面904可以包括图像2，图像2为缩略图903放大显示后所对应的图像，图像2也可以称为原始图像。
在手机显示图像展示界面904后，用户可以通过上述图5A至图8B所示的方式指示构图推荐模式，从而使得手机进入构图推荐模式，此处不再赘述。可以理解的是，除了图5A至图8B所示的方式以外，用户指示构图推荐模式的方式不限于此，本申请实施例对用户指示构图推荐模式的方式不作限定。
手机在首次或每次进入构图推荐模式后，可以通过在显示屏上显示或通过语音的 方式给用户以提示说明，以告知用户构图推荐模式的功能和作用。例如，手机可以通过显示文字信息提示用户“进入该模式后，针对当前图像为您呈现推荐图像，您可以点击选择想要的目标推荐图像”。再例如，参见图8C，手机可以通过窗口801来提示用户，在构图推荐模式下，基于原始图像为用户呈现推荐图像，用户可以根据习惯选择想要的目标推荐图像，并为用户提供一个构图推荐的示例802，以方便用户了解构图推荐模式的功能。
在进入构图推荐模式后，手机可以根据当前显示的原始图像进行构图推荐处理，为用户呈现推荐图像。其中，推荐图像是根据原始图像并基于推荐的构图方案生成的图像。手机为用户呈现推荐图像的方式可以有多种。
在一些实施例中，在用户通过上述图5A至图8B所示的方式指示构图推荐模式后，手机可以在原始图像的下方呈现推荐图像。例如，参见图10A，手机在原始图像的下方呈现出多种推荐图像，分别为推荐图像一11，推荐图像二12和推荐图像三13。可以理解的是，由于受到界面大小的限制，图10A所示的手机只能同时呈现少量几种推荐图像，但是手机可以呈现的推荐图像不限于该少量几种推荐图像。示例性地，当手机检测到用户在推荐图像上左右滑动时，可以呈现其他推荐图像。例如，参见图10B，用户可以在推荐图像上向右滑动，当手机检测到用户在推荐图像上向右滑动时，参见图10C，可以呈现推荐图像四14，推荐图像五15和推荐图像六16。
在另一些实施例中，在用户通过上述图5A至图8B所示的方式指示构图推荐模式后，手机可以显示图10D所示的构图推荐界面101。构图推荐界面101可以包括至少一个推荐图像，例如，可以包括推荐图像一11，推荐图像二12，推荐图像三13，推荐图像四14，推荐图像五15，推荐图像六16，推荐图像七17，推荐图像八18和推荐图像九19。类似地，当手机检测到用户在推荐图像上左右滑动时，可以呈现其他推荐图像。
在手机呈现图10A至图10D所示的推荐图像后，用户可以根据自己的审美习惯通过点击相应的推荐图像来选择想要的目标推荐图像。其中，目标推荐图像可以有一个或多个，本申请实施例对目标推荐图像的数目不作限定。
可见，本申请实施例提供的构图推荐方法能够针对用户感兴趣的目标图像显示推荐图像，该推荐图像基于推荐的构图方案得到，用户选择目标推荐图像后即可获取效果较好的图像，与现有技术中在相机预览模式下的构图引导方案相比，无需用户进行精准、持续且复杂的操作，从而提高了用户体验。同时，该方法无需在手机移动的过程中进行实时判断是否移动至最佳照片位置，从而能够有效降低终端设备硬件要求。并且，在本申请实施例提供的构图推荐方法中，针对用户感兴趣的目标图像才提供构图推荐功能，避免了无差别构图造成的资源浪费。
在一些实现方式中，用户还可以自行编辑原始图像以得到期望构图的图像。例如，参见图11A，用户可以通过图11A所示的裁剪控件111来完成对原始图像的构图。当手机检测到用户点击裁剪控件111的操作后，向用户呈现图11B所示的裁剪界面112，用户可以通过滑动图11B中的虚线所示的裁剪框来实现构图。示例性地，裁剪框可以为矩形框、方形框、圆形框或椭圆框等。参见图11C，手机可以响应于用户滑动裁剪框的操作来完成构图，得到图像113。
然后，手机可以自动保存该图像113。例如，手机可以在预设时间内未检测到用户操作后自动保存该图像113，比如，手机可以在3秒内未检测到用户操作后，自动保存该图像113。或者，手机可以响应于用户的预设操作保存该图像113。例如，图像展示界面还可以包括确定按钮，当手机响应于用户操作完成构图后，用户可以通过点击确定按钮来保存该图像113。再例如，手机可以响应于用户长按该图像113的操作后，保存该图像113。
可见，在用户自行编辑原始图像以得到期望的图像的方案中，用户可以根据自己的习惯自行编辑原始图像以得到想要的图像，该图像对应于符合用户审美的构图方案，从而使得本申请实施例提供的构图推荐方法更加灵活，并且充分考虑了用户意愿，用户体验较好。
在一些实施例中，在进入构图推荐模式后，除了当前显示的原始图像以外，手机还可以结合与当前显示的原始图像相关的其他图像进行构图推荐处理，为用户呈现推荐图像。
示例性地，其他图像可以为在拍摄原始图像时捕获的原始图像所对应的场景的图像。该图像的视野范围可以大于原始图像的视野范围。大视野范围的图像可以包括更多的对象和更大的环境范围，手机在当前显示的原始图像的基础上，可以结合大视野范围的图像向用户呈现更多的推荐图像，使得用户具有更多的选择。例如，对于原始图像仅拍摄到其一部分的对象，或未拍摄到的对象，手机可以结合大视野范围的图像进行合理的构图，展示完整的对象，从而可以向用户提供具有完整对象的推荐图像，提高了用户体验。
在一些实现方式中，手机在拍摄原始图像时，可以同时记录摄像头捕获的具有较大视野范围的图像。参见图12A，手机在拍摄预览界面可以显示图像1201，手机拍照后可以得到与图像1201对应的原始图像1202，同时手机还可以记录摄像头捕获的具有较大视野范围的图像，原始图像1202的视野范围可以包括在该图像的视野范围内。在拍摄场景下，手机可以同时记录原始图像和该图像。例如，原始图像1202可以如图12B所示；摄像头捕获的图像1203可以如图12C所示。在拍摄图像时，用户可能会缩放图像，使得拍摄预览界面上呈现的图像的视野范围可能小于摄像头的视野范围。在拍摄场景下，手机可以保存缩放后的图像以及摄像头采集到的较大视野范围的图像。这样，手机在使用原始图像的基础上，可以结合摄像头捕获的具有较大视野范围的图像进行合理的构图，向用户呈现更丰富的推荐图像，从而能够提高用户体验。
在另一些实现方式中，手机在拍摄原始图像时，可以同时拍摄另一图像，另一图像的视野范围可以大于原始图像的视野范围。例如，手机可以根据用户的指示进入双图拍摄模式，从而可以利用广角镜头拍摄原始图像，同时利用超广角镜头拍摄具有更大视野范围的另一图像。这样，手机可以利用原始图像以及与原始图像一起拍摄的具有较大视野范围的图像来进行构图推荐，从而可以向用户呈现更丰富的推荐图像，以提高用户体验。示例性地，图13A示出了利用广角镜头拍摄的原始图像1301，图13B示出了利用超广角镜头拍摄的图像1302，图13C示出了手机基于原始图像1301和图像1302生成的推荐图像1303。
在一些实施例中，手机进入构图推荐模式后，在拍摄场景下，手机可以在拍摄预 览界面根据当前取景框的图像为用户呈现推荐图像。例如，手机进入构图推荐模式后，在手机显示如图4B所示的拍摄预览界面403时，参见图14，手机可以根据当前拍摄预览界面的图像在拍摄预览界面403上为用户呈现推荐图像一11，推荐图像二12和推荐图像三13。然后，用户可以通过点击选择目标推荐图像来捕获该目标推荐图像所对应的图像。示例性地，在拍摄场景下，当手机检测到用户点击目标推荐图像的操作之后，手机可以自动拍摄该目标推荐图像所对应的图像。或者，在拍摄场景下，当手机检测到用户点击目标推荐图像的操作之后，手机可以自动拍摄该目标推荐图像所对应的图像以及当前取景框的图像。
在拍摄预览界面根据当前取景框的图像为用户提供推荐图像的方案中，用户只需要在推荐图像中进行选择，无需用户进行精准、持续且复杂的操作，仅需较少的用户参与就可以拍摄获得效果较好的图像，减少了用户在拍摄过程中的操作，用户体验较好。
上文已提到，在手机检测到用户用于指示构图推荐模式的操作后，手机进入构图推荐模式。在构图推荐模式下，手机可以根据当前显示的原始图像，利用构图推荐算法向用户提供推荐图像。其中，构图推荐算法可以有多种。构图推荐算法可以为人工智能(artificial intelligence，AI)算法。例如，构图推荐算法可以包括但不限于下述任一种算法：神经网络算法、决策树、线性算法、支持向量机(support vector machine，SVM)、Q表或深度学习算法等。在构图推荐模式下，手机可以根据当前显示的原始图像，利用该构图推荐算法向用户提供推荐图像。
示例性地，构图算法中可以包括美学评价模块，美学评价模块可以用于对推荐图像进行美学评估。例如，该美学评价模块可以为神经图像评估(neural image assessment，NIMA)，NIMA可以对推荐图像进行美学打分。本申请实施例对美学评价模块的类型不作限定。示例性地，构图推荐算法向用户提供的推荐图像可以为美学评价较高的图像。例如，构图推荐算法向用户提供的推荐图像可以为美学打分高于一定阈值的推荐图像。再例如，构图推荐算法向用户提供的推荐图像可以为所有待推荐图像中美学打分排名靠前的图像。
在构图推荐模式下，手机根据当前显示的原始图像向用户呈现推荐图像后，用户可以从推荐图像中选择符合用户审美的目标推荐图像。在用户选择了目标推荐图像后，手机可以保存该目标推荐图像。
示例性地，手机可以自动保存目标推荐图像。例如，手机可以在预设时间内未检测到用户操作后自动保存目标推荐图像，比如，在用户选择了目标推荐图像后，若手机可以在3秒内未检测到用户操作，则自动保存目标推荐图像。
再示例性地，手机可以响应于用户的预设操作保存目标推荐图像。例如，图像展示界面还可以包括确定按钮，当手机响应于用户操作完成构图后，用户可以通过点击确定按钮来保存目标推荐图像。再例如，手机可以响应于用户长按目标推荐图像的操作后，保存该目标推荐图像。
在一些实施例中，在手机保存目标推荐图像后，手机可以记录用户选择的目标推荐图像对应的目标构图方案，并根据用户选择的该目标构图方案对构图推荐算法进行修正，使得构图推荐算法能够学习用户的审美习惯，以便手机后续能够根据修正后的 构图推荐算法为用户呈现符合用户习惯的推荐图像。例如，参见图15A，在构图推荐模式下，手机根据原始图像1501向用户呈现推荐图像一11，推荐图像二12和推荐图像三13后，用户从推荐图像中点击选择推荐图像二12，手机可以记录用户的选择，然后根据用户的选择对构图推荐算法进行修正。后续若有与原始图像1501同样类型的图像，手机可以根据修正后的构图推荐算法向用户呈现符合用户审美习惯的推荐图像。示例性地，参见图15B，手机可以将符合用户审美习惯的推荐图像二12排在推荐图像的前面，使得用户能够容易地选择到符合其习惯的推荐图像。因此，手机可以根据用户的选择来自适应地学习用户的审美习惯，从而提升用户体验。
其中，图像的类型可以包括多种，例如，单人照，双人照，多人照，风景照，静物照等。每种类型的图像可以具有多种构图方案。例如，对于单人照，构图方案可以为全身照、半身照、人物居中、人物居左、或人物居右等。再例如，对于双人照，构图方案可以为左侧一人全身照、右侧一人全身照、两侧双人全身照、左侧一人半身照、或右侧一人半身照等。
在一些实现方式中，手机可以按照用户历史使用构图方案的次数优先推荐该构图方案所对应的图像。例如，在图像类型为双人照时，若手机检测到用户历史使用两侧双人全身照的构图方案次数最多，则手机可以优先推荐两侧双人全身照的构图方案所对应的图像。
在另一些实现方式中，手机可以按照用户最近使用的构图方案优先推荐该构图方案所对应的图像。例如，在图像类型为单人照时，若手机检测到用户最近使用人物居中的构图方案，则手机可以优先推荐人物居中的构图方案所对应的图像。
在另一些实现方式中，手机可以按照用户历史使用的构图方案的次数以及用户最近使用的构图方案优先推荐该构图方案所对应的图像。例如，在图像类型为双人照时，若手机检测到用户历史使用两侧双人全身照的构图方案次数最多，并且用户最近使用的构图方案为两侧双人全身照，则手机可以优先推荐两侧双人全身照的构图方案所对应的图像。可以理解的是，在一些实现方式中，手机还可以根据用户自行编辑原始图像而得到的目标图像对应的构图方案来对构图推荐算法进行修正，以便手机后续根据修正后的构图推荐算法推荐符合用户习惯的构图方案，以使得推荐的构图方案更能符合用户的审美需求。
示例性地，图16示出了本申请实施例提供的一种构图推荐方法的流程图。参见图16，首先，电子设备可以通过拍照功能获取图像。然后，电子设备可以对所获取的图像进行图像编辑。其中，图像编辑可以包括构图推荐。在进行图像编辑时，若电子设备检测到用户指示构图推荐模式的操作，则电子设备可以使用构图推荐算法对该图像进行处理，为用户呈现推荐图像，推荐图像是基于推荐的构图方案生成的图像。之后，用户可以选择想要的目标推荐图像，即选择了与目标推荐图像对应的目标构图方案，电子设备可以记录用户的选择，并根据该用户选择对构图推荐算法进行修正，使得手机后续能够根据修正后的构图推荐算法向用户呈现符合用户习惯的推荐图像。
结合上述实施例及相关附图，本申请实施例提供了一种构图推荐方法，该方法可以在如图2、图3所示的电子设备(例如手机、平板电脑等)中实现。如图17所示，该方法可以包括以下步骤：
