背景技术
相机的镜头是一组透镜，当平行于主光轴的光线穿过透镜时，光会聚到一点上，这个点称为焦点。焦点到透镜中心(即光心)的距离，称为焦距。焦距是相机进行图像拍摄时的重要参数之一。由于拍照时，被拍摄的物体与相机(镜头)的距离不总是相同的，即物距不总是固定的，所以，要想获得清晰的图像，通常需要随着物距的不同而改变胶片到镜头光心的距离，这个改变的过程通常称为“调焦”或“变焦”。
相关技术中，针对相机的焦距调节方式局限性较高，调焦时的人机交互性能较差。

参见图1，图1是本申请实施例提供的调焦系统的一个可选的架构示意图，为支撑一个调焦应用，在调焦系统100中，终端400(调焦设备，示例性示出了终端400-1和终端400-2)通过网络300连接服务器200，网络300可以是广域网或者局域网，又或者是二者的组合。下面结合在社交应用中，第一用户向第二用户发送拍摄的图片的场景为例进行调焦系统的说明。第一用户对应终端400-1，第二用户对应终端400-2。在社交应用的社交界面中，实现图像拍摄和图像发送的场景时，终端400-1，被配置为在拍摄目标对象的拍摄界面中，当显示有调焦提示控件时，接收作用于显示屏幕的第一区域的第一触控移动操作；所述第一区域为所述拍摄界面中的任意区域；所述第一触控移动操作的移动方向与第一方向之间的夹角小于或等于预设角度；所述第一方向为与所述调焦提示控件的排布轴向平行的方向；响应于所述第一触控移动操作，确定映射到所述调焦提示控件上的所述调焦位置；基于所述调焦位置，确定对应的调焦参数；基于所述调焦参数，调节拍摄所述目标对象的焦距，最终得到调焦完成时拍摄的最终图像；并将最终图像在图形界面401-1显示。

以下将结合本申请实施例提供的调焦设备的示例性应用和实施，并以调焦设备为终端，终端包括显示屏幕和拍摄装置(例如，相机)为例，说明本申请实施例提供的调焦方法。
图3是本申请实施例提供的调焦方法的一个可选的流程示意图，将结合图3示出的步骤进行说明。
S101、在拍摄目标对象的拍摄界面中，当显示有调焦提示控件时，接收作用于显示屏幕的第一区域的第一触控移动操作；第一区域为拍摄界面中的任意区域；第一触控移动操作的移动方向与第一方向之间的夹角小于或等于预设角度；第一方向为与调焦提示控件的排布轴向平行的方向。
在本申请的一些实施例中，当终端接收到相机触发指令时，可以控制相机进入拍摄界面，并同时在拍摄界面上的任意区域处显示调焦提示控件，以开启变焦功能。在变焦功能开启的情况下，终端可以通过显示屏幕的拍摄界面中的第一区域来接收用户的第一触控移动操作。
在本申请的一些实施例中，第一区域可以包括第二区域；如此，可以使用户既可以通过触控调焦提示控件的显示区域来进行焦距调节，也可以在不通过触控调焦提示控件对应的区域时，通过在拍摄界面的其他区域的触控移动操作，实现对相机的拍摄焦距的调节。
示例性的，在第一区域包含第二区域时，终端可以接收用户作用在调焦提示控件的显示区域的第一触控移动操作，并且，响应于在调焦提示控件的显示区域接收到的第一触控移动操作，确定对应的调焦参数，最终以确定的调焦参数调节拍摄目标对象的焦距。
在本申请的另一些实施例中，第一区域也可以是拍摄界面中除第二区域之外的区域，其中，第二区域是调焦提示控件的显示区域。
在本申请的另一些实施例中，在变焦功能开启的情况下，终端也可以通过显示屏幕的拍摄界面中的第 一区域和第二区域，来接收用户的第一触控移动操作。
在本申请的一些实施例中，拍摄界面可以是视频拍摄状态下终端的界面，也可以是拍照状态下的界面等，是相机工作下的拍摄界面即可，本申请实施例对此不作限定。当终端接收到相机触发指令，即用户在拍摄控制界面中点击拍摄控件时，可以控制相机进入拍摄界面，进行对目标对象的拍摄，并将拍摄的目标对象的图像实时显示在拍摄界面中。
需要说明的是，终端在拍摄界面中时，可以不是一进入拍摄界面就显示调焦提示控件，而是可以在拍摄界面中通过触控操作实现调焦提示控件的显示和退出显示的，后续将会进行详细的描述。
在本申请的另一些实施例中，调焦提示控件可以用于表征焦距的调整方向和调焦位置，以在用户调焦的过程中，显示实时调焦进度和实时调焦位置，从而对用户进行调焦操作的提示。其中，焦距的调整方向可以包括增大焦距和减小焦距。调焦提示控件的排布轴向可以是水平方向或垂直方向等，本申请实施例不作限制。但是第一触控移动操作的移动方向与第一方向之间的夹角小于或等于预设角度，其中，第一方向为与调焦提示控件的排布轴向平行的方向。
在本申请的一些实施例中，第一触控移动操作可以是沿预设方向进行滑动的触控操作，简称滑动操作。第一触控移动操作的移动方向为在显示屏幕上产生的移动轨迹中起始触控位置指向各个实时触控位置的延伸方向。在本申请的一些实施例中，第一触控移动操作可以是滑动方向与第一方向之间的夹角小于或等于预设角度的滑动操作，第一方向为与调焦提示控件的排布轴向平行的方向。
在本申请的一些实施例中，预设角度为事先设置的一个较小的角度或者角度范围，例如预设角度可以为30°以内，本申请实施例不作限制。
也就是说，当用户的手指在显示屏幕的第一区域的滑动方向和与调焦提示控件的排布轴向平行的方向之间的夹角小于或等于30°时，可以确定该滑动操作为第一触控移动操作。
示例性的，图4是本申请实施例提供的示例性的调焦提示控件在拍摄界面上的显示效果示意图。如图4所示，调焦提示控件100垂直排布在拍摄界面的10的第一区域11上。图5是本申请实施例提供的示例性的四个不同的滑动操作的滑动方向与第一方向之间的夹角关系示意图。如图5所示，Y表示与调焦提示控件100的排布轴向所平行的第一方向，Y包括两个相反的方向Y1和Y2，X表示与调焦提示控件100的排布轴向垂直的方向，O 0表示滑动操作的起始触控位置，O 1、O 2、O 3和O 4分别为四个不同的滑动操作在滑动过程中产生的一个实时触控位置(即实时触控点的位置)，O 0与O 1形成的方向Z1为第一个滑动操作的滑动方向，O 0与O 2形成的方向Z2为第二个滑动操作的滑动方向，依次类推，O 0与O 3形成的方向Z3为第三个滑动操作的滑动方向，O 0与O 4形成的方向Z4为第四个滑动操作的滑动方向。如图5所示，当滑动方向Z1、Z2、Z3或Z4与方向Y之间的夹角β小于或等于30°时，可以确定第一滑动操作、第二滑动操作、第三滑动操作或第四滑动操作为第一触控移动操作。
在本申请的另一些实施例中，终端可以通过滑动操作的起始触控位置与滑动过程中产生的至少一个实时触控位置之间的相对位置关系，确定该滑动操作的移动方向。
示例性的，图6是本申请实施例提供的示例性的第一触控移动操作的移动轨迹与第一方向之间的关系示意图。如图6所示，Y表示与调焦提示控件的排布轴向所平行的第一方向，Y包括两个相反的方向Y1和Y2，O 0表示第一触控移动操作的起始触控位置，O 1表示第一触控移动操作产生的一个实时触控位置。如图6所示，由于起始触控位置O 0位于实时触控位置O 1的下方，所以，终端可以确定起始触控位置O 0向上指向实时触控位置O 1。因此，终端可以确定向上的方向Y1为第一触控移动的移动方向。
S102、响应于第一触控移动操作，确定映射到调焦提示控件上的调焦位置。
在本申请的一些实施例中，终端通过显示屏幕接收到第一触控移动操作，就可以响应第一触控移动操作在移动过程中的移动距离和移动方向，确定出调焦提示控件上的实时调焦位置，并随着第一触控移动操作的移动过程，实时显示调焦提示控件上的实时调焦位置，从而使用户可以通过调焦提示控件上的实时调焦位置获知当前的调焦进度。
需要说明的是，在本申请实施例中，调焦提示控件包括调焦进度条和调焦提示控件，用户在终端的显示屏幕上的触控操作，即第一触控移动操作，可以对应控制调焦提示控件上的调焦控件的移动，得到用户在触控操作过程中，调焦控件在调焦进度条上的实时位置。
示例性的，图7是本申请实施例提供的示例性的调焦进度条和调焦控件在拍摄界面上的显示效果示意图。如图7所示，调焦提示控件100包括调焦进度条103和调焦控件104。调焦控件104在调焦进度条103上的位置可以随着第一触控移动操作的移动过程而进行相应变化。
在本申请的一些实施例中，第一触控移动操作对应的移动距离与调焦控件在调焦进度条上的调焦位置之间正相关，第一触控移动操作对应的移动距离，可以与调焦控件在调焦进度条上的调焦位置和调焦控件的初始位置之间的距离相对应。并且，当第一触控移动操作对应的移动轨迹的长度越长，调焦控件在调焦进度条上的调焦位置与调焦控件的初始位置之间的距离越远。
S103、基于调焦位置，确定对应的调焦参数。
在本申请的一些实施例中，调焦提示控件上的不同位置对应不同的调焦参数。终端确定出映射到调焦提示控件上的实时调焦位置，就可以确定出该实时调焦位置所对应的调焦参数。
在本申请的一些实施例中，本申请的调焦参数可以是焦距值或者预设单位时间内的焦距调节量等，本申请实施例不作限制。
示例性的，调焦提示控件上的一个位置所对应的调焦参数可以表示该位置对应的一个焦距值或焦距调节量等，本申请实施例不作限制。
示例性的，当调焦参数是焦距值，且当终端确定出调焦控件处于调焦进度条的第一位置处时，终端可以确定出该第一位置所对应的焦距值。
S104、基于调焦参数，调节拍摄目标对象的焦距。
在本申请的一些实施例中，终端获得焦距调节参数，可以根据焦距调焦参数增大或减小相机拍摄目标对象时的焦距。
在本申请的一些实施例中，当焦距调节参数为焦距值时，终端可以向相机发送调整指令，以使相机根据接收到的调整指令，直接将相机当前拍摄目标对象时的焦距调整为该焦距值；或者，当焦距调节参数为预设单位时间内的焦距调节量时，终端可以向相机发送调整指令，以使相机根据接收到的调整指令，采用该焦距调节量增大或减小当前拍摄目标对象时的焦距。
可以理解的是，在拍摄目标对象的拍摄界面，当变焦功能开启时，接收拍摄界面中的任意区域的第一触控移动操作，这样就可以通过触控任意区域实现调节拍摄目标对象的焦距的功能。也就是说，在没有调焦提示控件的区域中，也可以实现调焦触控操作，提高了调焦范围，进而提高了人机交互性能。
图8是本申请实施例提供的调焦方法的一个可选的流程示意图，调焦提示控件包括调焦进度条和调焦控件；上述S102可以通过S1021-S1023实现，将结合图8示出的步骤进行说明。
S1021、响应于第一触控移动操作的移动过程，确定预设单位时间内的实时移动距离和移动方向。
在本申请的一些实施例中，终端在接收到作用在显示屏幕上的第一触控移动操作时，可以在该第一触控移动操作的作用过程中，确定预设单位时间内的在显示屏幕上的实时移动距离和实时移动方向。
在本申请的一些实施例中，预设单位时间可以是终端在第一触控移动操作的移动过程中，获取第一触控移动操作的移动距离的频率。例如，频率可以为1秒或20毫秒等等，本申请实施例对此不作限定。当预设单位时间为1秒时，预设单位时间内的第一触控移动操作的实时移动距离则为每1秒内获取到的一个实时触控位置与起始触控位置之间的距离。
需要说明的是，在本申请实施例中，终端是在第一触控移动操作的移动过程，当每个预设单位时间到达时，进行实时移动距离和移动方向的确定的。
在本申请的一些实施例中，终端可以通过第一触控移动操作的起始触控位置和与预设单位时间对应的一个实时触控位置之间的相对位置关系，确定预设单位时间内的移动方向。
示例性的，如图6所示，以预设单位时间为1秒为例进行说明。O 0为第一触控移动操作的起始触控位置，O 1为第一触控移动操作的移动过程中与第1秒对应的实时触控位置，由于O 0位于实时触控位置O 1的下方，所以，起始触控位置O 0向上指向实时触控位置O 1，终端可以确定向上的方向Y1为第一触控移动操作在该第1秒对应的移动方向。
S1022、根据预设映射关系，将实时移动距离，映射为调焦控件在调焦进度条上的控件移动距离。
在本申请的一些实施例中，第一触控操作的实时移动距离与调焦控件的控件移动距离具有预设映射关系，根据该预设映射关系和第一触控操作的实时移动距离，终端在获得第一触控操作的实时移动距离后，可以根据该预设映射关系，将确定调焦控件在调焦进度条上的控件移动距离。其中，调焦提示控件包括调焦进度条和调焦控件。
在本申请的一些实施例中，第一触控移动操作可以作用在调焦进度条上，也可以作用在调焦提示控件上，本申请实施例对此不作限定。
需要说明的是，预设映射关系为显示屏幕上第一触控移动操作的移动距离与调焦提示控件上的调焦控件的移动距离的对应关系或比例关系。当终端在获得第一触控操作在显示屏幕上的实时移动距离后，可以根据第一触控操作的移动距离和该比例关系，换算出调焦控件在调焦进度条上的控件移动距离。
在本申请的一些实施例中，预设映射关系还可以转换为第一触控移动操作在显示屏幕上的移动速度和作用时间，映射到调焦提示控件上的移动速度和作用时间，从而来得到调焦控件的控件移动距离。
示例性的，当预设映射关系为移动轨迹的对应关系时，第一触控移动操作的实时移动距离与调焦控件的控件移动距离之间的预设映射关系可以为，第一触控移动操作的实时移动距离每增加200个像素点(pixel)时，则调焦控件在调焦进度条上移动0.2L。其中，L表示调焦进度条的总长度，预设映射关系可以根据实际需要任意设置，本申请实施例对此不作限定。
S1023、按照移动方向，将调焦控件在调焦进度条上移动控件移动距离，得到调焦位置。
在本申请的一些实施例中，终端在获得第一触控移动操作的预设单位时间内的移动方向，以及调焦控件在调焦进度条上的控件移动距离后，可以在该预设单位时间内，按照移动方向，将调焦控件在调焦进度条上移动该控件移动距离，得到实时的调焦位置。其中，实时的调焦位置为调焦控件在调焦进度条上的当前位置。
本申请实施例中，终端根据第一触控移动操作的移动距离和移动方向，确定调焦控件的移动控件移动距离，并将调焦控件在调焦进度条上移动控件移动距离，得到调焦位置。终端可以在调焦过程中根据用户在第一区域的第一触控移动操作，控制调焦提示控件上相应的调焦位置，并通过调焦进度条和调焦控件显示调焦位置，调焦过程更加直观。
图9是本申请实施例提供的调焦方法的一个可选的流程示意图，上述S1021可以通过S10211-S10212实现，将结合图9示出的步骤进行说明。
S10211、响应于第一触控移动操作的移动过程，确定第一触控移动操作的移动方向，以及显示屏幕上的起始触控位置和在预设单位时间内的触控移动过程中产生的实时触控位置。
在本申请的一些实施例中，终端在接收到第一触控移动操作时，可以在第一触控移动操作的作用过程中，在每次预设单位时间到达时，获取第一触控移动操作的起始触控位置和触控移动过程中产生的实时触控位置。
需要说明的是，在本申请实施例中，终端可以在每次预设单位时间到达时，进行触控移动操作的过程中的触控位置的获取。
示例性的，当预设单位时间为1秒时，则第一触控移动操作在每次1秒到达时，获取的触控移动过程中产生的实时触控位置为1秒所获取到的一个实时触控点的位置。即第1秒获取到一个实时触控点P1的位置，第2秒获取到一个实时触控点P2的位置。
S10212、将起始触控位置与实时触控位置之间的距离，作为实时移动距离。
在本申请的一些实施例中，终端在获得一个实时触控点的位置时，可以根据该实时触控点与起始触控点之间，沿与调焦提示控件的排布轴向平行的方向的距离作为实时移动距离。
示例性的，如图5为例进行说明，当触控位置为触控点的位置，且当预设单位时间为1秒时，O 0为第一触控移动操作的起始触控点，O 1为与第一触控移动操作的移动过程中第二个1秒时获得的实时触控点，则可以将起始触控点O 0与实时触控点O 1之间沿Y方向的距离，作为第一触控移动操作在预设单位时间内(即该第二个1秒)内的实时移动距离。
本申请实施例中，终端在第一触控移动操作的移动过程将第一触控移动操作的起始触控位置，与在预设单位时间内的触控移动过程中产生的实时触控位置之间的距离，作为实时移动距离。这样终端可以准确的确定在第一触控移动操作的移动过程中，第一触控移动操作的实时移动距离。
图10是本申请实施例提供的调焦方法的一个可选的流程示意图，调焦参数包括调焦速度。基于此，上述S103可以通过S1031实现，将结合图10示出的步骤进行说明。
S1031、基于预设的调焦控件的位置与调焦速度的对应关系，确定出调焦位置所对应的实时调焦速度，其中，一个调焦位置对应一个调焦速度。
在本申请的一些实施例中，调焦进度条上的不同位置对应不同的调焦速度，且每个位置与一个调焦速度唯一对应。当调焦控件位于调焦进度条的某一位置处时，该位置则为调焦位置，与该位置对应的调焦速度则为该调焦位置所对应的调焦速度。
在本申请的一些实施例中，调焦参数可以包括调焦速度，即预设单位时间内的焦距调节量。
在本申请实施例中，调焦速度包括：调焦方向标识，调焦数值和数值单位，本申请实施例不作限制。其中，调焦方向标识包括增大和减小两种标识。示例性的，增大标识可以为字符“+”，减小标识可以为字符“-”。
示例性的，调焦速度可以为+3X/S，其中，X表示焦距倍率，S表示秒(数值单位)，则+3X/S表示，每秒将相机的拍摄焦距增大3X(调焦数值)。
在本申请的一些实施例中，可以将调焦进度条的长度L沿中心位置划分为两部分L1和L2两部分，并将L1和L2分别划分为多个长度l，沿从中心位置处向调焦进度条两端的方向上，依次为每个长度l设置一个编号和调焦速度，并使L1部分中，调焦速度随着长度l的编号的递增而逐渐增大，使L2部分中，调焦速度随着长度l的编号的递增而逐渐减小，并将进度条的中心位置处的调焦速度设置为预设初始调焦速度；示例性的，预设初始调焦速度可以为0。如图11所示，图11是本申请实施例提供的示例性的调焦提示控件在部分拍摄界面上的显示效果示意图；当调焦控件104在调焦进度条103的中心位置处时，当前的调焦速度为0。
可以理解的是，通过上述的设置，当调焦控件在调焦进度条上向调焦进度条的一端移动而经过不同位 置时，调焦位置对应的调焦速度逐渐减小，并且，当调焦控件在调焦进度条上向调焦进度条的另一端移动而经过不同位置时，调焦位置对应的调焦速度逐渐增大。
示例性的，图12A是本申请实施例提供的另一示例性的调焦提示控件在部分拍摄界面上的显示效果示意图；图12B是本申请实施例提供的又一示例性的调焦提示控件在部分拍摄界面上的显示效果示意图。如图12A和12B所示，当调焦控件104在调焦进度条103上沿着方向Y1(与调焦提示控件100的排布轴向平行的方向)向调焦进度条的一端移动而经过不同位置时，调焦速度会从-1X/S逐渐增大至+2X/S，对应的相机的焦距也增大，并且表示，从每秒减少1X焦距变化为每秒增加2X焦距。
在本申请的另一些实施例中，还可以将调焦进度条的长度L均匀划分为多个长度l，依次为每个长度l设置一个编号和一个调焦速度V，且，随着长度l编号的递增，长度l所对应的调焦速度V逐渐增大。例如，将调焦进度条的长度L划分为100个长度l，使第一个长度l所对应的调焦速度V1，小于第二个长度l所对应的调焦速度V2，依次类推，则编号最大的长度l所对应的调焦速度为最大调焦速度。
在本申请的另一些实施例中，终端在确定出调焦位置对应的调焦参数(实时的调焦参数)后，还在拍摄界面中显示该调焦参数，以向用户进行提示，从而使调焦过程更直观。
本申请实施例中，当调焦参数包括调焦速度时，终端根据调焦位置所对应的实时调焦速度，进行相机的拍摄焦距的调焦，可以使调焦位置可以与调焦过程相对应，从而可以使调焦过程更直观。
图13是本申请实施例提供的调焦方法的一个可选的流程示意图，上述S104可以通过S1041实现，将结合图13示出的步骤进行说明。
S1041、在预设单位时间内，按照实时调焦速度，调节拍摄目标对象的焦距。
在本申请的一些实施例中，当终端获得与调焦位置对应的实时调焦速度后，可以在在预设单位时间内，以获得的实时调焦速度，调节拍摄目标对象的焦距。
在本申请的实施例中，调焦速度的时间单位可以为该预设时间单位。
示例性的，当调焦速度为+3X/S时，则该预设时间单位为1S(秒)。
在本申请的一些实施例中，由于调焦位置与第一触控移动操作的实时移动距离相关，而第一触控移动操作的实时移动距离与第一触控移动操作在预设单位时间内的实时触控位置相关。所以，当终端以预设获取频率获取第一触控移动操作的触控位置时，每个获取时间点(预设单位时间内)会对应一个触控位置，该触控位置会对应一个调焦位置，而一个调焦位置对应一个调焦速度；所以，每个预设单位时间对应一个调焦速度。终端可以在该预设单位时间内以对应的调焦速度，调节相机的拍摄焦距。例如，第一个1秒(预设单位时间)时，调焦位置为第一调焦位置，则第一个1秒时，以第一调焦位置对应的调焦速度V1进行调焦；当第二个1秒时，调焦位置位于第二调焦位置，则第二个1秒时，以第二调焦位置对应的调焦速度V2进行调焦；当第三个1秒时，若调焦位置仍为第二调焦位置，则第三个1秒时，仍以第二调焦位置对应的调焦速度V2进行调焦等，直至调焦速度到达调焦速度的上限值或者下限值。
图14是本申请实施例提供的调焦方法的一个可选的流程示意图，调焦提示控件包括调焦方向标识，调焦方向标识包括第一方向标识和第二方向标识；第一方向标识表征增大焦距，第二方向标识表征减小焦距；实时调焦速度包括调焦方向标识和调焦速率。上述S1041可以通过S301-S303实现，将结合图14示出的步骤进行说明。
S301、根据预设的方向标识与调焦方向标识的映射关系，确定出实时调焦速度的调焦方向标识对应的调整方向。
在本申请的一些实施例中，终端在获得实时调焦速度后，可以先确定出该实时调焦速度的调焦方向标识和调焦速率，然后，根据预设的方向标识与调焦方向标识的映射关系，确定出是要将焦距增大，还是减小。
在本申请的一些实施例中，调焦提示控件包括调焦方向标识，调焦方向标识包括第一方向标识和第二方向标识。第一方向标识表征增大焦距，第二方向标识表征减小焦距；实时调焦速度包括调焦方向标识和调焦速率。
示例性的，第一方向标识可以为字符“+”，第二方向标识可以为字符“-”，且，第一方向标识与第二方向标识分别位于调焦进度条的两端。
示例性的，图15是本申请实施例提供的示例性的调焦提示控件在拍摄界面上的显示效果示意图。如图15所示，第一方向标识可以为字符“+”101，表征增大焦距，第二方向标识可以为字符“-”102，表征减小焦距；并且第一方向标识101和第二方向标识102分别显示在调焦进度条的两端。并且，如图15所示，当调焦控件104在调焦距进度条103上沿Y1方向，向靠近字符“+”101运动时，可以表征当前正增大焦距，当调焦控件104在调焦距进度条103上沿Y2方向，向靠近字符“-”101运动时，表征当前正减小焦距。
在本申请实施例中，实时调焦速度的调焦方向标识也可以为字符“+”或字符“-”，本申请实施例不作限制。例如，当实时调焦速度为+3X/S时，则字符“+”为方向标识，3X/S为该实时调焦速度的调焦速率；又 例如，当实时调焦速度为-1X/S时，字符“-”为方向标识，1X/S为该实时调焦速度的调焦速率。
在本申请的一些实施例中，终端可以为调焦方向标识与焦距的调整方向预先设定相互映射关系。例如，可以使调焦方向标识“+”与增大焦距互相对应，并使调焦方向标识“-”与减小焦距对应；当确定出的调焦速度是+2X/S时，则可以根据预先设定的调焦方向标识与焦距的调整方向之间的映射关系，确定调焦方向标识“+”与增大焦距对应，从而确定出+2X/S为每秒将相机的拍摄焦距增大2X。
S302、当调整方向为增大焦距时，在预设单位时间内，按照实时调焦速度的调焦速率，增大拍摄目标对象的焦距。
在本申请的一些实施例中，当终端根据调焦速度的调焦方向标识确定增大焦距时，可以在预设单位时间到达时，以调焦速度的调焦速率增大相机拍摄目标对象时的焦距。例如，当调焦速度是+2X/S时，则可以在确定调焦方向标识“+”与增大焦距对应之后，以每秒增大2X的速率，增大相机在拍摄目标对象时的焦距。
S303、当调整方向为减小焦距时，在预设单位时间内，按照实时调焦速度的调焦速率，减小拍摄目标对象的焦距。
在本申请的一些实施例中，当终端根据调焦速度的调焦方向标识确定增大焦距时，可以在预设单位时间达到时，以调焦速度的调焦速率增大相机在拍摄目标对象时的焦距。例如，当调焦速度是-2X/S时，则可以在确定调焦方向标识“-”与减小焦距对应之后，以每秒减小2X的速率，减小相机在拍摄目标对象时的焦距。
本申请实施例中，终端根据预设的方向标识与调焦方向标识的映射关系，确定是否增大或减小拍摄目标对象的焦距，并根据确定出的调整方向以确定出的调焦速率进行焦距的调节。这样终端可以在根据调焦速度进行相机的拍摄焦距的调节的同时，直观显示焦距的调整方向，从而使调焦过程更直观。
图16是本申请实施例提供的调焦方法的一个可选的流程示意图，上述S302可以通过S3021实现，将结合图16示出的步骤进行说明。
S3021、在预设单位时间内，按照实时调焦速度的调焦速率增大拍摄目标对象的焦距，直至调整后的焦距达到最大焦距阈值时，停止变焦。
在本申请的一些实施例中，相机的焦距具有一个数值范围，该范围包括了最大数值，相机的焦距可在该数值范围内进行增大，直至达到数值范围的最大数值。示例性的，最大数值可以是60X。
在本申请的实施例中，在第一触控移动操作的触控过程中，当终端确定在预设单位时间到达时第一触控移动操作对应的调整方向为增大焦距时，终端会根据获取到的实时调焦速度所对应的调焦速率，在预设单位时间到达时，增大拍摄目标对象的焦距，并实时判断增大后的焦距是否达到最大焦距阈值，直至焦距达到最大焦距阈值时，停止变焦。
在本申请的实施例中，当用户在调焦提示控件的显示区域中输入的第一触控移动操作为上滑操作时，终端会确定出上滑操作对应的调整方向为增大焦距，在预设单位时间到达时，以实时调焦速度对应的调焦速率增大拍摄目标对象的焦距，并实时判断增大后的焦距是否达到最大焦距阈值，并当增大后的焦距值达到最大焦距阈值时，终端停止变焦。
例如，当用户通过手指在调焦提示控件的显示区域中输入的第一触控移动操作为上滑的操作时，终端会确定出上滑操作对应的调整方向为增大焦距，在每1秒到达时，以实时调焦速度对应的调焦速率增大拍摄目标对象的焦距，并实时判断增大后的焦距是否达到最大焦距阈值，并当增大后的焦距达到最大焦距阈值时，终端停止变焦。也就是说，当终端根据用户手指输入的上滑操作，而将焦距增大到最大焦距阈值后，即使用户的手指仍在继续上滑，终端也不会继续增大拍摄目标对象的焦距。
在本申请的一些实施例中，如图16所示，上述S303可以通过S3031实现：
S3031、在预设单位时间内，按照实时调焦速度的调焦速率减小拍摄目标对象的焦距，直至调整后的焦距达到最小焦距阈值时，停止变焦。
在本申请的实施例中，在第一触控移动操作的触控过程中，当终端确定在预设单位时间到达时第一触控移动操作对应的调整方向为减小焦距时，终端会根据获取到的实时调焦速度所对应的调焦速率，在预设单位时间到达时，减小拍摄目标对象的焦距，并实时判断减小后的焦距是否达到最小焦距阈值，直至焦距达到最小焦距阈值时，停止变焦。
在本申请的实施例中，当用户在调焦提示控件的显示区域中输入的第一触控移动操作为下滑操作时，终端会确定出下滑操作对应的调整方向为减小焦距，在预设单位时间到达时，以实时调焦速度对应的调焦速率减小拍摄目标对象的焦距，并实时判断减小后的焦距是否达到最小焦距阈值，并当减小后的焦距达到最小焦距阈值时，终端停止变焦。
例如，当用户通过手指在调焦提示控件的显示区域中输入的第一触控移动操作为下滑操作时，终端会确定出下滑操作对应的调整方向为减小焦距，在每1秒到达时，以实时调焦速度对应的调焦速率减小拍摄 目标对象的焦距，并实时判断减小后的焦距是否达到最小焦距阈值，并当减小后的焦距达到最小焦距阈值时，终端停止变焦。也就是说，当终端根据用户手指输入的下滑操作，而将焦距减小到最小焦距阈值后，即使用户的手指仍在继续下滑，终端也不会继续减小拍摄目标对象的焦距。
在本申请的一些实施例中，相机的焦距具有一个数值范围，该范围包括了最小数值，相机的焦距可在该数值范围内进行减小，直至达到数值范围的最小数值。示例性的，最小数值可以是5X。
本申请实施例中，由于终端在将焦距调整到最大焦距阈值或最小阈值时会停止变焦，因此，可以避免在相机的拍摄焦距已达到最大且无法继续增大，或者在相机的拍摄焦距已达到最小且无法继续减小时，仍继续调焦而带来的耗费终端电量和资源的问题，从而可以降低终端的资源浪费。
在本申请的一些实施例中，上述S302还可以通过S3022实现，上述S303还可以通过S3032实现，具体如下：
S3022、当调整方向为增大焦距，且实时调焦速度的调焦速率为最大调焦速率时，在每个预设单位时间内，按照最大调焦速率，持续增大拍摄目标对象的焦距。
在本申请的实施例中，当终端确定第一触控移动操作对应的实时调整方向为增大焦距，且确定出实时调焦速度已经达到最大调焦速率时，终端可以在每个预设单位时间达到时，持续按照该最大调焦速率进行焦距调节。
在本申请的实施例中，调焦速率对应有最大调焦速度(调焦速度的上限值)。示例性的，最大调焦速度可以是+3X/S，则最大调焦速度对应的最大调焦速率为3X/S。
在本申请的实施例中，当用户在调焦提示控件的显示区域中输入的第一触控移动操作为上滑操作时，终端会确定出该上滑操作所对应的调整方向为增大焦距，并判断实时调焦速度的调焦速率是否为最大调焦速率，并当实时调焦速度的调焦速率为最大调焦速率时，在每个预设单位时间到达时，以最大调焦速率持续增大拍摄目标对象的焦距。
例如，当用户通过手指在调焦提示控件的显示区域中输入的第一触控移动操作为上滑操作时，终端会确定出该上滑操作对应的调整方向为增大焦距，并判断实时调焦速度的调焦速率是否为最大调焦速率3X/S，并当实时调焦速度的调焦速率为最大调焦速率3X/S时，在每1秒到达时，以最大调焦速率3X/S，持续增大拍摄目标对象的焦距。
S3032、当调整方向为减小焦距，且实时调焦速度的调焦速率为最大调焦速率时，在每个预设单位时间内，按照最大调焦速率，持续减小拍摄目标对象的焦距。
在本申请的一些实施例中，当终端确定第一触控移动操作对应的实时调整方向为减小焦距，且确定出实时调焦速度已经达到最大调焦速率时，终端可以在每个预设单位时间达到时，持续按照该最大调焦速率进行焦距调节，直到将相机的拍摄焦距调至最小焦距时，停止调焦操作。
在本申请的一些实施例中，调焦速率对应有最小调焦速度(调焦速度的下限值)，示例性的，最小调焦速度可以是-3X/S，则最小调焦速度对应的最大调焦速率为3X/S。
在本申请的实施例中，当用户在调焦提示控件的显示区域中输入的第一触控移动操作为下滑操作时，终端会确定出该下滑操作所对应的调整方向为减小焦距，并判断实时调焦速度的调焦速率是否为最大调焦速率，并当实时调焦速度的调焦速率为最大调焦速率时，在每个预设单位时间到达时，以最大调焦速率持续减小拍摄目标对象的焦距。
例如，当用户通过手指在调焦提示控件的显示区域中输入的第一触控移动操作为下滑操作时，终端会确定出该下滑操作对应的调整方向为减小焦距，并判断实时调焦速度的调焦速率是否为最大调焦速率3X/S，并当实时调焦速度的调焦速率为最大调焦速率3X/S时，在每1秒到达时，以最大调焦速率3X/S，持续减小拍摄目标对象的焦距。
在本申请的一些实施例中，在终端会以最大调焦速率，持续增大拍摄目标对象的焦距，直至将焦距增加至最大焦距时，停止变焦，或者，直至第一触控移动操作结束时，停止变焦。
在本申请的一些实施例中，在终端会以最大调焦速率，持续减小拍摄目标对象的焦距，直至将焦距减小至最小焦距时，停止变焦，或者，直至第一触控移动操作结束时，停止变焦。
在本申请的一些实施例中，第一触控移动操作是持续的操作，在第一触控移动操作持续的过程中，当触控位置实时变化时，响应于第一触控移动操作，确定出的映射到调焦提示控件上的调焦位置也实时变化，进而基于调焦位置而确定的调焦速度也是实时变化的。而当触控位置不再变化时，终端根据该触控位置确定出的调焦提示控件上的调焦位置也不再变化，进而基于调焦位置确定出的实时调焦速度也不再变化。所以，即使实时调焦速度不是最大调焦速率，在实时的调焦位置不变的情况下，终端也可以该实时调焦速度持续增大或减小拍摄目标对象的焦距，直至将焦距减小至最小焦距时，停止变焦，或者，直至第一触控移动操作结束时，停止变焦。
图17是本申请实施例提供的调焦方法的一个可选的流程示意图，上述S101之前还可以包括： S1001-S1002，将结合图17示出的步骤进行说明。
S1001、在拍摄界面中，接收到作用于显示屏幕上任意位置处的第二触控移动操作。
在本申请的一些实施例中，当终端进入相机的拍摄模式后，可以在拍摄界面的任意位置处接收第二触控移动操作。
在本申请的一些实施例中，第二触控移动操作可以是沿预设方向进行滑动的触控操作。
在本申请实施例中，第二触控移动操作可以是上滑操作或下滑操作，其中，该上滑操作或下滑操作可以是滑动方向与相机的拍摄界面上的水平方向或垂直方向之间的夹角小于或等于预设角度的滑动操作，本申请实施例不作限制。
在本申请的另一些实施例中，第二触控移动操作还可以是触控点击操作等其他触控移动操作，本申请实施例对此不作限定。

在本申请的一些实施例中，调焦提示控件的显示区域，即上述的第二区域，可以与第一区域不同。如此，可以使用户在不通过触控调焦提示控件100对应的区域时，也可以通过在拍摄界面的其他位置的触控移动操作，实现对相机的拍摄焦距的调节，提高了调焦操作的范围。在本申请的一些实施例中，为了不影响对拍摄对象的拍摄图像的预览，可以在拍摄界面的拍摄边界附近显示调焦提示控件，例如上述图18所示的调焦提示控件100。
在本申请的一些实施例中，当终端响应于第二触控移动操作，开启变焦功能，在显示屏幕的第二区域显示调焦提示控件时，如上述图11所示，在显示屏的第二区域显示调焦提示控件时，调焦控件104可以在调焦进度条103的中心位置处时，且当前的调焦速度为0。
本申请实施例中，在拍摄界面中，终端根据接收到的显示屏幕上任意位置处的第二触控移动操作，开启变焦功能，并在显示屏幕的第二区域显示调焦提示控件；可以在接收到用户在显示屏幕的第二区域内输入的第二触控移动操作时，开始显示调焦提示控件，从而可以通过调焦提示控件向用户进行焦距的调整方向和调焦位置的反馈，使调焦过程更直观。

S1004、基于预设初始调焦速度，调节焦距。
在本申请的一些实施例中，终端在获取到预设初始调焦速度后，可以在没有检测到第一触控移动操作之前，先以该预设初始调焦速度，调节终端的拍摄焦距。
本申请实施例中，终端在拍摄界面中，接收到作用于显示屏幕上任意位置处的第二触控移动操作之后，以获取的预设初始调焦速度调节焦距；可以在不需要用户手动调节的情况下，进行焦距的自动调焦，相比于用户手动调焦而言，增加了终端的调焦方式，改善了终端的调焦局限性。
