方法实施例
本公开实施例提供了一种自拍校准视线的方法，参见图1，该方法包括：
S101、在自拍模式下，实时跟踪用户视线；
S102、当检测到拍照指令后，显示引导视线动画，引导用户视线从当前视 线位置移动到摄像头对应的屏幕位置，并进行连拍。
也就是说，在自拍模式下，本公开通过显示引导视线动画，引导用户视线到摄像头对应的屏幕位置，再进行拍照，即，本公开通过在自拍时校准用户的眼神，从而避免出现因为用户视线落在屏幕中部看预览或者落在快门按钮上导致的视线偏下无神的问题。
本公开实施例所述步骤S102可以包括：
通过终端摄像头的追踪系统以实时追踪用户的视线。
本公开可通过视线追踪器来实时追踪用户的视线，也就是说，本公开可在终端中设置视线追踪器等视线追踪装置，来实现在自拍模式下实时追踪用户的视线。
本公开实施例所述的引导视线动画为一个虚拟光标或者是实时缩小的当前取景界面。
需要说明的是，本公开实施例所述的虚拟光标可以是一个十字形状或者箭头形状虚拟光标等等，当然本领域的技术人员也可以预设一个固定的小图标等以引导用户视线。
相对于相关终端，将取景框缩小放置在距离摄像头较近的屏幕上方，从而让用户看小的取景框按下快门时，获得视线直视摄像头的效果的方式，由于本公开的引导视线动画仅仅是一个虚拟光标或者是实时缩小的当前取景界面，所以本公开不会缩小用户观察用的预览框，也不会造成屏幕遮挡。
本公开实施例所述方法还包括：在屏幕上预设免引导区域和需引导区域；
图2是本公开实施例的屏幕的区域划分示意图，如图2所示，免引导区域为距离摄像头预定距离半径的屏幕区域，需引导区域为屏幕上免引导区域以外的屏幕区域。
当然实施时，本领域的技术人员以及用户也可以根据实际需要来设置上述的免引导区域和需引导区域，例如，设定距离摄像头预定长度距离和宽度距离的屏幕区域为免引导区域，即，设置预定的矩形区域或正方形区域为免引导区 域，免引导区域以外的屏幕区域为需引导区域。
图3是本公开实施例的引导视线的路线示意图，如图3所示，在自拍模式下，本公开通过显示引导视线动画，引导用户视线到摄像头对应的屏幕位置，再进行拍照，需要说明的是，本公开所显示的引导视线动画可以为一直线，即，引导视线动画的运动轨迹是一条直线，直接将用户视线引导到摄像头对应的屏幕位置，引导视线动画的运动轨迹也可以是一条弧线，通过一个弧线来将用户视线引导到摄像头对应的屏幕位置。
本公开实施例所述步骤S202可以包括：
当检测到拍照指令后，判断用户视线是否在预设的免引导区域内，如果在预设的免引导区域内，则直接进行拍照；如果不在预设的免引导区域内，则显示引导视线动画，引导用户视线从当前视线位置移动到摄像头对应的屏幕位置，并进行连拍。
也就是说，本公开在显示引导视线动画前，先判断用户视线是否在预设的免引导区域内，如果在预设的免引导区域内，则直接进行拍照；如果不在预设的免引导区域内，则显示引导视线动画，引导用户视线从当前视线位置移动到摄像头对应的屏幕位置，并进行连拍。

步骤401、前摄开启；
步骤402、判断是否开启标准模式，如果未开启标准模式，进入S403，如果开启标准模式，进入S404；
步骤403、结束；
步骤404、跟踪用户视线；
可以开启人脸识别功能，并实时跟踪用户视线所在屏幕区域；
步骤405、检测用户是否按下快门，判断用户视线是否在免引导区域，如果按下快门并且用户视线在免引导区域，进入S406，如果未按下快门或用户视线不在免引导区域，进入S407；
可以将屏幕区域分为免引导区域和需引导区域，免引导区域为靠近硬件摄像头所在位置的区域，需引导区域为较为远离硬件摄像头所在位置的其他区域；
步骤406、直接进行拍照；
步骤407、显示引导视线动画，引导用户视线从当前视线位置移动到摄像头对应的屏幕位置，并进行连拍；
实施时，可以以x秒(例0.5秒)为间隔启动连拍拍摄，同时以用户按下快门视线所在屏幕区域为起点，以硬件摄像头位置为终点，提供视觉引导动画，该动画可以是以一个虚拟元素移动的形式，也可以是将当前取景界面实时缩小移动的形式，以提供一个让用户视线跟随移动的元素；移动速度可以设置为y mm/s，也可以采用将整个动画时间控制在z秒内的方式进行设置；动画结束，连拍也同时结束，生成n张连拍照片；
步骤408、对连拍后的图片进行自动识别，挑选出满足预设清晰度的图片。
可以将n张照片进行照片清晰度评价，剔除清晰度较低的照片，并在剩余照片中，选择最后一张成像的照片作为最优选择呈现出来，因为此时用户视线距离摄像头位置最近，是最有可能为最佳角度的照片，同时，用户可以通过按钮或者手势调出查看其他备选照片，用户可以最终确认保留的照片，当然用户也可以从剔除清晰度较低的照片后剩余的图片中挑选最佳照片保存。
总体来说，本公开在自拍时打开校准模式，拍摄时如果视线偏下，即可在按下快门后根据动画引导移动视线位置，通过连拍，最终自动或者手动选择一张眼神最为灵动的照片。
装置实施例
本公开实施例提供了一种自拍校准视线的装置，参见图5，该装置包括：跟踪单元在自拍模式下，实时跟踪用户视线；处理单元当检测到拍照指令后，显示引导视线动画，引导用户视线从当前视线位置移动到摄像头对应的屏幕位置，并进行连拍。
也就是说，在自拍模式下，本公开通过跟踪单元实时跟踪用户视线，并通过处理单元显示引导视线动画，引导用户视线到摄像头对应的屏幕位置，再进行拍照，即，本公开通过在自拍时校准用户的眼神，从而避免出现因为用户视线落在屏幕中部看预览或者落在快门按钮上导致的视线偏下无神的问题。
实施时，本公开实施例所述的跟踪单元可以通过终端摄像头的追踪系统以实时追踪用户的视线。
可通过视线追踪器来实时追踪用户的视线，也就是说，本公开可在终端中设置视线追踪器等视线追踪装置，来实现在自拍模式下实时追踪用户的视线。
本公开实施例所述的引导视线动画为一个虚拟光标或者是实时缩小的当前取景界面。
需要说明的是，本公开实施例所述的虚拟光标可以是一个十字形状或者箭头形状虚拟光标等等，当然本领域的技术人员也可以预设一个固定的小图标等以引导用户视线。
相对于相关终端，将取景框缩小放置在距离摄像头较近的屏幕上方，从而让用户看小的取景框按下快门时，获得视线直视摄像头的效果的方式，由于本公开的引导视线动画仅仅是一个虚拟光标或者是实时缩小的当前取景界面，所以本公开不会缩小用户观察用的预览框，也不会造成屏幕遮挡。
本公开实施例所述方法还包括：在屏幕上预设免引导区域和需引导区域；
图2是本公开实施例的屏幕的区域划分示意图，如图2所示，免引导区域为距离摄像头预定距离半径的屏幕区域，需引导区域为屏幕上免引导区域以外的屏幕区域。
当然实施时，本领域的技术人员以及用户也可以根据实际需要来设置上述的免引导区域和需引导区域，例如，设定距离摄像头预定长度距离和宽度距离的屏幕区域为免引导区域，即，设置预定的矩形区域或正方形区域为免引导区域，免引导区域以外的屏幕区域为需引导区域。
图3是本公开实施例的引导视线的路线示意图，如图3所示，在自拍模式下，本公开通过显示引导视线动画，引导用户视线到摄像头对应的屏幕位置，再进行拍照，需要说明的是，本公开所显示的引导视线动画可以为一直线，即，引导视线动画的运动轨迹是一条直线，直接将用户视线引导到摄像头对应的屏幕位置，引导视线动画的运动轨迹也可以是一条弧线，通过一个弧线来将用户视线引导到摄像头对应的屏幕位置。
本公开所述的装置还可以包括：设置单元；
设置单元，被配置为在屏幕上预设免引导区域和需引导区域；
所述处理单元还被配置为，当检测到拍照指令后，判断用户视线是否在预设的所述免引导区域内，如果在预设的所述免引导区域内，则直接进行拍照；如果不在预设的所述免引导区域内，则显示引导视线动画，引导用户视线从当前视线位置移动到摄像头对应的屏幕位置，并进行连拍。
也就是说，本公开在显示引导视线动画前，先判断用户视线是否在预设的免引导区域内，如果在预设的免引导区域内，则直接进行拍照；如果不在预设的免引导区域内，则显示引导视线动画，引导用户视线从当前视线位置移动到摄像头对应的屏幕位置，并进行连拍。
本公开实施例所述方法还包括：对连拍后的图片进行自动识别，挑选出满足预设清晰度的图片。
总体来说，本公开是在前摄自拍时提供视线校准模式，在该模式下，用户在预览界面先确认好姿势角度后按下快门键时，识别用户面部位置后，从用户眼睛位置给出视线引导图形动画至摄像头对应的屏幕位置，用户根据此引导视线动画转移视线时，启动连拍，引导动画结束后，将该组连拍呈现给用户，用户可以挑选最佳照片保存。
本公开实施例中的相关内容可参照装置实施例和方法实施例部分进行理解，在此不再赘述。
终端实施例
本公开实施例提供了一种终端，该终端包括装置实施例中所述的任意一种装置，本公开实施例所述的终端为任意具有自拍的终端，如、手机、平板电脑，等等。
本公开实施例还提供了一种非暂态计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令设置为执行上述任一实施例中的方法。
本公开实施例还提供了一种电子设备的结构示意图。参见图6，该电子设备包括：
至少一个处理器(processor)60，图6中以一个处理器60为例；和存储器(memory)61，还可以包括通信接口(Communications Interface)62和总线63。其中，处理器60、通信接口62、存储器61可以通过总线63完成相互间的通信。通信接口62可以用于信息传输。处理器60可以调用存储器61中的逻辑指令，以执行上述实施例的方法。
此外，上述的存储器61中的逻辑指令可以通过软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。
存储器61作为一种计算机可读存储介质，可用于存储软件程序、计算机可执行程序，如本公开实施例中的方法对应的程序指令/模块。处理器60通过运行存储在存储器61中的软件程序、指令以及模块，从而执行功能应用以及数据处理，即实现上述方法实施例中的自拍校准视线的方法。
存储器61可包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序；存储数据区可存储根据终端设备的使用所创建的数据等。此外，存储器61可以包括高速随机存取存储器，还可以包括非易失性存储器。
本公开实施例的技术方案可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括一个或多个指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本公开实施例所述方法的全部或部分步骤。而前述的存储介质可以是非暂态存储介质，包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等多种可以存储程序代码的介质，也可以是暂态存储介质。
本公开实施例中的相关内容可参照装置实施例和方法实施例部分进行理解，在此不再赘述。
本公开可以至少可以达到以下的有益效果：
本公开在自拍模式下，通过显示引导视线动画，引导用户视线到摄像头对应的屏幕位置，再进行拍照，也就是说，本公开通过在自拍时校准用户的眼神，从而避免出现因为用户视线落在屏幕中部看预览或者落在快门按钮上导致的视线偏下无神的问题。
尽管为示例，已经公开了本公开的实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本公开的范围应当不限于上述实施例。
