具体实施例
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述 的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1示出了根据本发明一个实施例的一种智能手表的拍照处理方法的流程示意图。如图1所示，该方法包括：
步骤S110，响应于智能手表进入拍照模式的事件，启动拍照功能并获取智能手表的摄像头模块所采集到的图片。
步骤S120，对于获取到的每帧图片：依据第一压缩标准，对该图片进行压缩处理。
步骤S130，将处理后的图片在智能手表的屏幕上进行显示。
可见，图1所示的方法响应于智能手表进入拍照模式的事件，启动拍照功能并获取智能手表的摄像头模块所采集到的图片，基于压缩后的图片尺寸小于原图片尺寸，对压缩后的图片进行显示的速度快于对原图片进行显示的速度的原理，本方案对获取到的每帧图片进行压缩处理后再显示在智能手表的屏幕上，通过对第一压缩标准的选择，使得智能手表的摄像头模块所采集的每一帧图片均能够快速地显示以供用户预览，使用户预览过程中不会出现卡顿现象，解决了智能手表因配置较低不足以对原图片进行流畅显示的问题，提高用户使用智能手表的拍照体验。
例如，用户在使用智能手表时，触发智能手表进入拍照模式，智能手表的拍照功能开启，智能手表的摄像头模块感应外界环境的输入光线开始按照一定频率采集图片；在智能手表的屏幕上按照摄像头模块采集图片的时序，依次显示每一帧图片以供用户预览，以使用户在预览过程中选择合适的取景。然而，现有技术中智能手表受自身硬件配置所限，对每一帧图片进行处理的速度很慢，导致在智能手表的屏幕上依次显示每帧图片时达不到每秒钟15帧的人眼可接受的实时性，在用户看来会出现卡顿。依据图1所示的方法，对于从智能手表的摄像头模块获取的每一帧图片，在显示之前先进行压缩处理，通过选择第一压缩标准，一方面，使得压缩后的图片在智能手表的屏幕上能够流畅快速显示，达到每秒钟15帧以上的显示频率，避免了预览过程中的卡顿现象，提高用户在拍照前的预览体验，保证当前智能手表的摄像头所采集的图片与当前智能手表的屏幕上所显示的图片在用户可察觉的范围内的同步性；另一方面，由于智能手表的屏幕都比较小，用户从智能手表的屏幕上预览图片时并不会觉察到图片由于压缩而导致的清晰度的下降。
在本发明的一个实施例中，上述步骤S120依据第一压缩标准，对该图片进行压缩处理的步骤包括：获取智能手表的屏幕的分辨率；以及，根据所获取的智能手表 的屏幕的分辨率，将该图片压缩为适配于智能手表的屏幕的尺寸，即，以智能手表的屏幕的分辨率作为第一压缩标准的参考。例如，智能手表为儿童手表，儿童手表的摄像头模块的分辨率为1600像素×1200像素，而儿童手表的屏幕的分辨率是240像素×240像素，当使用儿童手表的用户触发儿童手表进入拍照模式时，依次获取摄像头模块所采集的每帧图片，采用无损压缩技术，将该图片从1600像素×1200像素压缩为适配于智能手表的屏幕的240像素×240像素，再在屏幕上显示，使得每帧图片从采集到显示之间的处理时间压缩到原来的3％，提高显示频率。
当然，在本发明的其他实施例中，上述骤S120可以按照其他标准对获取的每帧图片进行不同程度的压缩，不限于将图片压缩至适配于智能手表的屏幕尺寸的压缩，无论采取何种第一压缩标准对图片进行压缩，只要是通过压缩图片实现将图片的处理时间缩短使得图片在智能手表的屏幕上的显示频率达到每秒钟15帧以上的人眼可接受的流畅程度即可，可根据实际情况进行选择。
在本发明的一个实施例中，图1所示的方法在将处理后的图片在智能手表的屏幕上进行显示之前，该方法进一步包括：对压缩后的图片进行智能图像处理；则所述将处理后的图片在智能手表的屏幕上进行显示包括：将智能图像处理之后的图片在智能手表的屏幕上进行显示。其中，由于图片已被压缩，使得智能处理过程的时间也大大缩短。
其中，在一个具体的实施例中，上述对压缩后的图片进行智能图像处理的过程包括两种方案：
方案一，包括以下两种方式中的任一种方式或两种方式的组合：方式一，统计该图片的全图灰度信息，判断该全图灰度信息(例如全图的平均灰度值)是否低于预设阈值，若是，则对该图片进行亮度调整。方式二，将该图片分为背景区域和前景肤色区域，对该图片进行分区域处理，对背景区域做平滑和/或锐化处理，对前景肤色区域进行饱和度调整、美白、和/或嫩肤处理。
例如，对于压缩后的一帧图片进行智能图像处理，一种情况下，统计该图片的全图平均灰度值为80，低于本例中全图平均灰度值的预设阈值120，表示该图片亮度过低，将该图片的亮度调高，完成对该图片的智能图像处理。另一种情况下，在上述将该图片的亮度调高之后，还进一步将该图片分为背景区域和前景肤色区域，对背景区域进行平滑处理和锐化处理二者中的任一种或两种处理，对前景肤色区域进行饱和度调整处理、美白处理和嫩肤处理三者中的任一种或多种处理。另一种情况下，无需调整该图片的亮度，将该图片分为背景区域和前景肤色区域，对背景区 域进行平滑处理和锐化处理二者中的任一种或两种处理，对前景肤色区域进行饱和度调整处理、美白处理和嫩肤处理三者中的任一种或多种处理。
方案二，检测压缩后的该图片中的五官点，所述五官点包括：该图片中对应于人眼的两个点、对应于鼻尖的点、和对应于嘴角的两个点；根据检测到的五官点获知该图片中的人脸分布状态；从素材库中获取特效素材，将特效素材附加在该图片中的人脸的相应部位上。
其中，上述检测压缩后的该图片中的五官点的过程是：根据人脸五官模型，检测压缩后的该图片中的五官点。具体地，人脸五官模型是通过人工智能深度学习技术训练而形成的，对于经过长期训练而形成的人脸五官模型，在训练过程中需要大量的样本数据和较长的训练时间，占用大量的系统资源，不适于在智能手表本地进行训练，智能手表可以从其他终端或服务器获取已训练形成的人脸五官模型进行预存，在需要检测图片中的五官点的时候直接使用；对于经过短期训练而形成的人脸五官模型，在训练过程中需要较少的样本数据和较短的训练时间，对系统资源的占用有限，可以在智能手表本地进行训练，智能手表在需要检测图片中的五官点之前或之后快速训练形成人脸五官模型并加以使用。
进一步地，在上述检测压缩后的该图片中的五官点的过程中，在检测出一帧图片中的五官点后，还可以采用智能预测和跟踪算法，在短时间内检测到下一帧图片中的五官点，具体地，在检测该图片中的五官点的每一点时，根据所检测的前一帧图片中的相应点的位置，在该位置周围的预设区域范围内进行检测。本实施例所采用的智能预测和跟踪算法，基于相邻两帧图片中的同一五官点所在位置不会差距太远的规律，利用上一帧图片中检测出的五官点的位置从下一帧图片中检测相应的五官点，缩小检测范围，提高五官点的检测效率，进一步提高智能图像处理的速度，即缩短每帧图像从采集到显示的处理过程的时间，在具体的例子中，单帧图片的处理过程平均耗时60ms，预览时能够达到近似实时，满足用户需求。
上述各实施例说明了智能手表进入拍照模式后，在屏幕上准实时地显示图片以供用户预览使用户选择合适的取景的过程，在用户选择到合适的取景后，将触发智能手表的拍照控件进行拍照，则图1所示的方法进一步包括：
步骤S140，响应于智能手表的拍照控件被触发的事件，获取拍照控件被触发时智能手表的摄像头模块所采集到的图片。
本步骤中，拍照控件被触发时智能手表的摄像头模块所采集到的图片即反应了用户的取景选择。
步骤S150，利用第一线程对该图片执行所述压缩处理、并对压缩处理后的图片执行智能图像处理和在智能手表的屏幕上进行显示的步骤。
步骤S160，利用第二线程对该图片进行所述智能图像处理，将智能图像处理后的图片保存在智能手表的相册根目录下。
上述步骤S150和步骤S160同时利用两个线程分别对获取到的同一帧图片进行不同的处理：第一线程(也可称为主线程)对该图片进行压缩处理，对压缩处理后的图片进行智能图像处理，将智能图像处理后的图片在智能手表的屏幕上进行显示，其中，压缩处理、智能图像处理以及显示的过程已在上文中说明，由于先对图像的压缩而导致处理时间有效缩短；第二线程(也可称为副线程)直接对该图片进行智能图像处理，再将智能图像处理后的图片保存在相册根目录下，使得相册根目录下所保存的图片是符合摄像头模块的分辨率的图片。其中，第一线程和第二线程可以是预先创建的，也可以是在获取摄像头模块采集的图片后再创建的，本发明对此不做限制。
依据本实施例，由于所获取的原图片的分辨率较大，处理和保存所耗费的时间较长，不能快速实时地为用户进行显示，因此同时利用两个线程，第一线程处理压缩图片尽快在屏幕上显示出拍照效果，第二线程处理原始分辨率图片并保存，使得用户在屏幕上看到的小图片与相册中保存的图片除了分辨率不同，其他显示效果完全一样，且保存的是高清图片。
进一步地，基于上述过程，该方法还包括：响应于智能手表的图片共享控件被触发的事件，将智能手表的相册根目录下的相应图片通过有线或无线的方式发送至其他终端设备。依据本实施例，可以将智能手表上保存的原始分辨率的高清拍摄图片与通讯录中好友的智能手表、绑定的智能手机等其他移动终端进行图片传输，或者直接通过数据线拷贝至PC机，图片显示效果较好，符合用户需求。
在本发明的另一个实施例中，还进一步提供了定时拍照的功能，该方法进一步包括：设置定时器，响应于智能手表的拍照控件被触发的事件，开启定时器进行计时，当到达预设时刻时，获取到达该预设时刻时智能手表的摄像头模块所采集到的图片；利用该第一线程对该图片执行所述压缩处理、并对压缩处理后的图片执行智能图像处理和在智能手表的屏幕上进行显示的步骤；利用该第二线程对该图片进行所述智能图像处理，将智能图像处理后的图片保存在智能手表的相册根目录下。其中，第一线程和第二线程可以是预先创建的，也可以是在获取摄像头模块采集的图片后再创建的，本发明对此不做限制。
