具体实施方式
目前，手机等移动终端中相机的性能不断的优化，人们利用移动终端进行拍摄的场景越来越多。同时，随着审美水平的提高，人们对照片的布局、人物表情等的要求也越来越高。在摄影师和用户距离较远或其他不便于交流的场景中，用户或摄影师需要不断的移动到对方所在的位置，以交流照片的成像效果。示例性的，可参见图1。
图1是现有照片拍摄过程示意图。请按照图1，摄影师与用户(即被拍摄对象)相距较远，拍摄照片后，用户移动到摄影师身边看照片的整体布局和人物表情等成像效果。若不满意，则重新回到原位摆拍。
上述摄影师和用户距离较远或其他不便于交流的场景中，需要摄影师或用户往复移动到对方位置才能交流成像效果。显然，该过程比较浪费时间，甚至无法拍摄到效果良好的照片。因此，用户如何获取摄影师拍摄的照片效果，是急待解决的问题。
有鉴于此，本申请实施例提供一种图片传输方法及设备，第一电子设备将拍摄得到的图片的成像效果发送给用户的第二电子设备，以供用户查看第一电子设备拍摄的图片的成像效果，提升拍摄效率的同时提高拍摄图片的质量。

图5A是本申请实施例提供的图片传输方法中一个手机的界面变化过程示意图。请参照图5A，用户摆好姿势后，摄影师调整手机位置等使得用户处于取景框的合适位置后，点击拍照按钮生成第一图片，该第一图片默认被保存在相册里。之后，摄影师点击相册，手机显示第一图片，同时，手机屏幕的下方显示“编辑”、“批注”、“分享”、“删除”等按钮。摄影师继续点击“分享按钮”，手机下方显示一系列分享渠道，该些分享渠道包括分享成像效果。摄影师点击“分享成像效果”按钮后，手机界面弹出浮窗，浮窗上显示与手机建立网络连接的智能可穿戴设备。摄影师可以从该些智能可穿戴设备中选择一个或多个，如图中摄影师选中智能手表2。之后，手机屏幕上出现提示框，提示摄影师是否需要将第一 图片的成像效果发送给智能手表2。摄影师对“取消”或“发送”按钮进行点击，从而选择是否发送成像效果。点击完毕后，手机屏幕跳转到拍摄界面。
图5A中，手机同时与多个可穿戴智能设备连接，因此，需要提示摄影师选择向哪些智能可穿戴设备分享成像效果。当与手机连接的可穿戴智能设备只有一个时，无需提示摄影师选择智能可穿戴设备。
图5B是本申请实施例提供的图片传输方法中一个手机的界面变化过程示意图。请参照图5B，摄影师点击手机上的图库，从图库中选择要分享成像效果的第一图片，如3月15日拍摄的一幅图片。之后，手机屏幕全屏显示第一图片，同时手机屏幕的下方显示“编辑”、“批注”、“分享”、“删除”等按钮。之后的流程参见上述图5A的描述，此处不再赘述。
图5C是本申请实施例提供的图片传输方法中一个手机的界面变化过程示意图。请参照图5C，摄影师预先开启了分享成像效果的功能，健康运动APP的界面上显示“分享成像效果”按钮。摄影师点击APP界面上的“分享成像效果”按钮后，手机屏幕弹出浮窗，浮窗上显示“拍摄”、“从相册选择”、“取消”等选项。摄影师点击“从相册选择”按钮后，手机屏幕上显示很多图片的缩略图。然后，摄影师从中选择待分享成像效果的图片，如9、14、16。假设最多可以选5张图片，则手机屏幕上显示完成按钮，该按钮提示当前选中的数量与总数量。之后，摄影师点击完成，手机屏幕弹出提示框，提示摄影师是否需要将第一图片的成像效果发送给智能手表2。摄影师对“取消”或“发送”按钮进行点击，从而选择是否发送成像效果。点击完毕后，手机屏幕跳转到APP界面。
上述图5A-图5C中，最后的提示框中是以显示第一图片的缩略图为例进行说明，然而本申请实施例并不以此为限制，其他可行的实现方式中，也可以是第一图片中人物的人脸区域、摆拍评分+拍照建议等。示例性的，可参见图5D。
图5D是本申请实施例提供的图片传输方法中一个手机的界面示意图。请参照图5D，从左到右依次是分享缩略图、人脸区域、摆拍评分+拍照建议。摆拍评分可以是微笑评分、姿势评分等，拍照建议可以是表情建议、姿势建议等。例如，微笑评分为20分，拍照建议为“嘴角上扬更阳光”。
图5D中，缩略图、人脸区域、摆拍评分+拍照建议是手机根据智能手表的屏幕规格信息对第一图片处理得到的成像效果，该些成像效果可以是一个个的第二图片，该些第二图片的大小形状与第二电子设备的显示屏的形状相同，第二图片的大小与第二电子设备的显示屏的大小的差值小于预设阈值，例如满屏显示或占据智能手表的大部分面积。也就是说，手机可以一次性将多个第一图片的成像效果发送给智能手表。
图5D中，人脸区域可以视为第一图片中目标对象的目标区域，当第一图片中的目标对象有多个时，不同目标对象对应不同的第二图片，各第二图片包含不同目标对象的目标区域。
上述实施例中，摆拍评分可以是微笑评分、姿势评分等，手机的拍照界面还可以显示微笑评分或姿势评分，供摄影师指导用户摆拍。示例性的，可参见图5E-图5G。
图5E是本申请实施例提供的图片传输方法中一个手机的界面示意图。请参照图5E，目标对象的微笑程度不同时，微笑评分是不同的。手机可以通过人脸检测等方式，从第一图片中提取出人脸区域，再从人脸区域中识别出露齿比例、嘴唇曲线、眼睛曲线、苹果肌 比例等，利用该些曲线计算微笑程度，根据危险程度确定微笑评分。
图5F是本申请实施例提供的图片传输方法中微笑评分的示意图。请参照图5F，方框分别为右眼、左眼、右苹果肌、左苹果肌和嘴巴所在区域，手机利用人脸识别技术，从人脸区域中识别出五官和牙齿，按照如下公式确定微笑评分：
P＝w 1x 1+w 2x 2+w 3x 3+w 4x 4
其中：
Figure PCTCN2021080134-appb-000001
图5G是本申请实施例提供的图片传输方法中一个手机的界面示意图。请参照图5G，手机本地或远程数据库中存储很多示例性的拍照姿态、拍照表情等。手机进入拍照界面后，手机屏幕上会显示拍照姿态、拍照表情分类，如图5G中的小孩、女士、男士、情侣、团体等标签按钮。摄影师点击某个标签按钮，如男士标签，则手机识别背景并在拍照界面显示适用于男士的拍照姿势，如图中虚线所示，摄影师可以通过向上或向下滑动等方式切换不同的姿势。手机提取出用户的姿势曲线，然后确定用户的姿势曲线和推荐姿势的姿势曲线的相似度，根据相似度确定出姿势评分并显示。或者，手机提取出用户的姿势特征，根据该姿势特征得到一个姿势向量，然后确定用户的姿势向量和推荐姿势的姿势向量的距离，根据距离确定出姿势评分并显示。摄影师根据姿势评分等，提示用户如何摆拍，比如，摄影师根据推荐姿态做出对应的姿势以提示用户，或者，摄影师通过语言的方式提示用户等。
上述实施例中，若用户查看第一图片的成像效果后向摄影师反馈意见，则摄影师可以通过手机界面进行相应的操作。示例性的，请参照图5H。
图5H是本申请实施例提供的图片传输方法中一个手机的界面变化过程示意图。请参照图5H，摄影师点击发送按钮并收到用户的反馈的指示信息时，若指示信息用于指示保留第一图片，则手机自动保存第一图片并显示“返回”或“分享”按钮，若摄影师点“返回”按钮，则回到上一级菜单或进入拍摄界面；若用户点击“分享”按钮，则进一步的将该第一图片分享至微信、微博等等。
上述实施例中，若摄影师拍摄照片前选中一些图片处理功能，如滤镜、美颜等，则手机拍照时，对拍摄到的照片进行滤镜、美颜等处理，利用处理后的照片得到上述的成像效果，再将成像效果发送给智能手表。示例性的，可参见图5I，图5I是本申请实施例提供的图片传输方法中一个手机的界面变化过程示意图。请参照图5I，星星样式的按钮表示关闭美颜，摄影师点击星星样式的“美颜”按钮，使得相机切换到轻度美颜模式，之后，摄影师继续点击轻度美颜模式，则进入深度美颜模式。从美颜相机关闭至深度美颜过程中，若 摄影师仅在深度美颜模式下拍照，则手机利用深度美颜后的图片得到各成像效果并发送给智能手表。
上述图5A-图5I中，均是以摄影师触发才能将第一图片的成像效果分析给智能手表。然而，本申请实施例并不限制，其他可行的实现方式中，手机和智能手表建立无线连接，且摄影师开启“分析成像效果”功能后，手机每次拍照后，都自动将成像效果分享给智能手机。
最后，智能手表如何显示成像效果并反馈意见。示例性的，可参见图6A-图6C。
图6A是本申请实施例提供的图片传输方法中用户查看成像效果的过程示意图。请参照图6A，拍照过程中，由于被拍的用户不方便解锁手机、抱小孩等原因，若摄影师通过手机上的聊天工具等传输拍摄到的照片，则被拍的用户需要点亮手机、打开聊天工具等，特别麻烦。而本申请实施例中，用户佩戴智能手环，抬起手腕即可看到智能手表的屏幕，通过简单的切屏、点击等操作，就可以查看成像效果并向摄影师反馈意见。
图6B是本申请实施例提供的图片传输方法中可穿戴设备屏幕变化的过程示意图。请参照图6B，智能手表接收到用于表征第一图片的成像效果的第二图片后，智能手表的屏幕上显示提示图标，用户点击提示图标，智能手表的屏幕上显示成像效果，如缩略图等。同时，智能手表的屏幕上还显示提示信息，该提示信息用于指示手机删除或保留第一图片。例如，图6B中的“×”表示用户不满意，删除第一图片，“√”表示用户满意，保留第一图片。
图6C是本申请实施例提供的图片传输方法中可穿戴设备屏幕变化的过程示意图。请参照图6C，智能手表接收到用于表征第一图片的成像效果的第二图片后，直接在智能手表的屏幕上显示成像效果，如缩略图等。
图6D是本申请实施例提供的图片传输方法中可穿戴设备屏幕变化的过程示意图。请参照图6D，智能手表接收到用于表征第一图片的成像效果的第二图片后，智能手表的屏幕上显示提示图标，用户点击提示图标，智能手表的屏幕上显示成像效果，如缩略图等。同时，智能手表的屏幕上还显示提示信息，该提示信息用于指示用户是否满意或不满意，例如，图6D中“×”表示用户不满意，删除第一图片，“√”表示用户满意，保留第一图片。假设用户选择“√”，则智能手表弹出浮窗或切换到提示窗口，浮窗或切换到提示窗口内显示保存在手机、同时保存在手机、仅保存原图等选项供用户选择。
另外，用户在智能手表的显示屏上选择“√”后，可以无需弹出提示框，默认同时保存在手机、智能手表上；或者，默认仅保存在手机上。实际实现时，可以通过运动健康APP等进行设置。
上述图6B～图6D中，以可穿戴设备的屏幕最后显示第一图片的缩略图为例进行说明，然而本申请实施例并不以此为限制，其他可行的实现方式中，也可以是第一图片中人物的人脸区域、摆拍评分+拍照建议等。示例性的，可参见图6E。
图6E是本申请实施例提供的图片传输方法中可穿戴设备的界面示意图。请参照图6E，从左到右依次是分享缩略图、人脸区域、摆拍评分+拍照建议。摆拍评分可以是微笑评分、姿势评分等，拍照建议可以是表情建议、姿势建议等。例如，微笑评分为20分，拍照建议为“嘴角上扬更阳光”。
上述图6A-图6E中，缩略图、人脸区域、摆拍评分+拍照建议是手机根据智能手表的 屏幕规格信息对第一图片处理得到的成像效果，该些成像效果可以是一个个的第二图片，该些第二图片的大小形状与第二电子设备的显示屏的形状相同，第二图片的大小与第二电子设备的显示屏的大小的差值小于预设阈值，例如满屏显示或占据智能手表的大部分面积。也就是说，手机可以一次性将多个第一图片的成像效果发送给智能手表。当手机一次性发送多个第二图片时，每个目标对象都有对应的三幅第二图片，分别是：缩略图、人脸区域、摆拍评分+拍照建议。为了方便不同目标对象的切换，以及同一目标对象的缩略图、人脸区域、摆拍评分+拍照建议的切换，可以通过切屏方式实现切换。示例性的，可参见图6F和图6G。
图6F是本申请实施例提供的图片传输方法中可穿戴设备屏幕变化的过程示意图。请参照图6F，第一图片包括两个人物和一棵树，则手机将这两个人物分别作为目标对象，针对每个目标对象，分别生成缩略图、人脸区域、摆拍评分+拍照建议，得到6个第二图片。然后，手机将该6个第二图片发送给智能手表。用户可以通过左右切屏的方式，查看同一个目标对象的缩略图、人脸区域、摆拍评分+拍照建议。
图6G是本申请实施例提供的图片传输方法中可穿戴设备屏幕变化的过程示意图。相较于图6F，用户可以通过上下切屏的方式，切换不同的目标对象。
图6F和图6G中，每个目标对象的缩略图可以是：以目标对象的中心为基准点，从第一图像中裁剪出的面积接近于智能手表屏幕的图片，这样裁剪的结果是不同目标对象可以对应同样的缩略图。然而，本申请实施例并不限制，例如，为了查看所有目标对象在第一图片中的整体布局，可以以第一图片的中心为基准点，从第一图像中裁剪出的面积接近于智能手表屏幕的图片，这样一来，每个目标对象对应同一个缩略图。
需要说明的是，虽然上述实施例是以左右切屏以切换不同的成像效果、上下切屏以切换不同的目标对象为例，对本申请实施例进行说明。然而，本申请实施例并不以此为限制，例如，其他实现方式中，可以是上下切屏以切换不同的成像效果、左右切屏以切换不同的目标对象；再如，也可以仅左右切屏，智能手表依次显示完同一个目标对象的缩略图、人脸区域、摆拍评分+拍照建议后，再显示下一个目标对象的缩略图、人脸区域、摆拍评分+拍照建议。
下面，基于上述的各个界面图，对本申请实施例提供的图片传输方法进行详细说明。示例性的，可参见图7，图7是本申请实施例提供的图片传输方法的流程图，包括：

手机在得到边长为e、可包含用户五官的最小正方形后，确定圆形智能手表的直径d与正方形边长e的比值d/e＝f，根据该比值f确定如何处理正方形的人脸区域：
当f＜1时，缩小正方形，使得可包含用户五官的最小正方形的边长e变小，得到边长为d、包含用户五官的正方形。之后，以该缩小后的正方形的几何中心为基准点、d/2为半径，从缩小后的正方形中截取出人脸区域；
