下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
本发明实施例提供一种手动对焦的控制方法。该方法应用于拍摄设备，所述拍摄设备包括用于手动调节的对焦调节组件。图1为本发明实施例提供的手动对焦的控制方法的流程图。如图1所示，本实施例中的方法，可以包括：
步骤S101、获取所述对焦调节组件当前的调整位置。
如图2所示，拍摄设备20可以是相机、摄像机、或其他具有拍摄功能的设备例如智能终端等。拍摄设备20可以是手持的拍摄设备，也可以 是搭载在可移动平台例如无人机上的拍摄设备。如图2所示，拍摄设备20包括对焦调节组件21，对焦调节组件21可以和拍摄设备20的光学组件耦合，对焦调节组件21可用于调节光学组件的焦点。该对焦调节组件包括如下至少一种：对焦环、调节按钮、调整轮。本实施例以对焦环为例进行示意性说明，当用户转动该对焦环时，光学组件的焦点将随着对焦环的转动而改变。如图2所示，用户可以沿着顺时针方向转动该对焦环，也可以沿着逆时针方向转动该对焦环。可以理解，该对焦环在其转动范围内转动，当该对焦环在某一时刻转动到某一位置时，该位置可以作为该对焦环在该时刻的调整位置。
在本实施例中，拍摄设备20还可以包括控制装置，该控制装置可以设置在拍摄设备20机身上，或者该控制装置可以是机身的一部分。在一些实施例中，控制装置可以独立于机身，也可以和机身耦合。该控制装置可以与对焦调节组件21电连接，并实时获取对焦调节组件21当前的调整位置。
在一些实施例中，拍摄设备20还可以通过远程控制器进行控制。远程控制器可以是拍摄设备20对应的专用控制器，也可以是其他安装有控制程序的终端设备，例如智能手机、平板电脑等。远程控制器和拍摄设备20可以进行有线通信或无线通信。远程控制器可以包括控制装置，该控制装置可以实时接收拍摄设备20发送的对焦调节组件21当前的调整位置。
步骤S102、根据所述对焦调节组件当前的调整位置，计算所述对焦调节组件当前的调整位置对应的当前对焦值。
当对焦调节组件21调整光学组件的焦点时，当前对焦值会发生改变。例如，当对焦环转动时，当前对焦值会发生改变，同时，当前对焦值可以反映出对焦环的转动位置。
在一些实施例中，根据对焦调节组件21的反馈可直接获得当前对焦值。在另外一些实施例中，还可以通过对焦评价函数计算出当前对焦值。在一些实施例中，当前对焦值可以是根据当前对焦调整参数捕获的图像使用对焦评价函数计算的值。在另外一些实施例中，当前对焦值可以与对焦评价函数的变量相关联，或者与对焦评价函数的变量相对应的参数相关联。
步骤S103、若所述当前对焦值等于对焦参数峰点值，且所述对焦调节 组件的调整位置继续变化，则从所述当前对焦值等于所述对焦参数峰点值对应时刻开始的预设时间内控制所述对焦调节组件停止调焦。
如图2所示，22表示拍摄设备20的显示组件例如显示屏，23表示显示组件22显示的当前图像中的对焦对象。
在一种可能的实现方式中，拍摄设备20通过光学组件获取图像数据，拍摄设备20中的控制装置计算当前图像中对焦对象在合焦时的对焦参数峰点值。
在另一种可能的实现方式中，拍摄设备20通过光学组件获取图像数据之后，将图像数据发送给远程控制器，由远程控制器的控制装置计算当前图像中对焦对象在合焦时的对焦参数峰点值。
具体的，控制装置对当前图像进行分析，得到对焦评价函数，进一步根据对焦评价函数计算当前图像中对焦对象在合焦时的对焦参数峰点值。此处不限定具体的对焦评价函数，也不限定确定对焦评价函数的具体方法，可选的，控制装置可基于频域分析、信息论、或差分运算等确定对焦评价函数。
如图2所示，假设在t0时刻，对焦调节组件21的调整位置在位置A，此时，对焦调节组件当前的调整位置对应的当前对焦值不等于对焦参数峰点值，拍摄设备20的光学组件没有完全聚焦于对焦对象，对焦对象在拍摄画面中不够清晰，用户继续调整对焦调节组件21，例如沿着顺时针方向调整该对焦调节组件21，在t1时刻，对焦调节组件21的调整位置在位置B，假设此时，对焦调节组件的调整位置对应的当前对焦值等于对焦参数峰点值，拍摄设备20的光学组件完全聚焦于对焦对象，对焦对象在拍摄画面中清晰可见，位置B可以作为对焦对象合焦时的对焦位置。但是，用户可能觉得此时对焦对象在拍摄画面中不够清晰，希望该对焦对象可以在拍摄画面中更加清晰一些，从而继续调整该对焦调节组件21，例如继续沿着顺时针方向调整该对焦调节组件21，在t2时刻，对焦调节组件21的调整位置在位置C。
在本实施例中，当控制装置在t1时刻确定出当前对焦值等于对焦参数峰点值，在t1时刻之后，根据对焦调节组件实时的调整位置，确定该对焦调节组件的调整位置继续变化，例如从t1时刻到t2时刻，对焦调节组件 21的调整位置在不断变化，则该控制装置从当前对焦值等于所述对焦参数峰点值对应时刻即t1时刻开始的预设时间内控制对焦调节组件21停止调焦，也就是说，在t1时刻，当前对焦值等于对焦参数峰点值，且t1时刻之后该对焦调节组件的调整位置继续变化，t2时刻在从t1时刻开始的预设时间内，则在t1时刻到t2时刻之间，该控制装置控制对焦调节组件21停止调焦，即从t1时刻到t2时刻，尽管用户还在调整对焦调节组件21，但是对焦调节组件21已经停止调焦，即对焦调节组件21已经停止调整光学组件的焦点，保持当前对焦值等于对焦参数峰点值，从而保持对焦对象在拍摄画面中清晰可见。
本实施例通过获取对焦调节组件当前的调整位置，根据该对焦调节组件当前的调整位置计算所述对焦调节组件当前的调整位置对应的当前对焦值，当该当前对焦值等于对焦参数峰点值时，继续获取对焦调节组件的调整位置，以确定该对焦调节组件的调整位置是否继续变化，如果在当前对焦值等于对焦参数峰点值之后，该对焦调节组件的调整位置继续变化，则从当前对焦值等于所述对焦参数峰点值对应时刻开始的预设时间内控制所述对焦调节组件停止调焦，也就是说，在该预设时间内尽管用户还在调整对焦调节组件，但是对焦调节组件已经停止调焦，即对焦调节组件已经停止调整光学组件的焦点，保持当前对焦值等于对焦参数峰点值，从而保持对焦对象在拍摄画面中清晰可见，解决了当前对焦值等于对焦参数峰点值之后用户继续调整对焦调节组件而导致用户很难找准对焦对象合焦时的对焦位置的问题。
本发明实施例提供一种手动对焦的控制方法。图3为本发明另一实施例提供的手动对焦的控制方法的流程图。如图3所示，在图1所示实施例的基础上，本实施例中的方法，还可以包括：
步骤S301、计算所述拍摄设备的显示组件显示的当前图像中的对焦对象对应的所述对焦参数峰点值。
具体的，控制装置计算拍摄设备的显示组件显示的当前图像中的对焦对象在合焦时的对焦参数峰点值。
步骤S302、控制所述显示组件显示第一指示标志，所述第一指示标志 用于指示所述对焦参数峰点值。
如图4所示，当控制装置计算出对焦对象在合焦时的对焦参数峰点值后，控制显示组件22显示第一指示标志41，第一指示标志41用于指示所述对焦参数峰点值，此处只是示意性说明，并不限定第一指示标志41的具体形状。
步骤S303、控制所述显示组件显示第二指示标志，所述第二指示标志用于指示所述当前对焦值。
另外，该控制装置还可以控制显示组件22显示第二指示标志42，本实施例不限定第二指示标志42的具体形状。
第二指示标志42用于指示对焦调节组件21当前的调整位置对应的当前对焦值，其中，所述第一指示标志和所述第二指示标志之间的指示距离，与所述对焦参数峰点值和所述当前对焦值之间的差值相关。
如图4所示，在t0时刻，对焦调节组件21的调整位置在位置A，当前对焦值小于对焦参数峰点值，第二指示标志42位于第一指示标志41的左侧，第二指示标志42和第一指示标志41之间的指示距离越大，当前对焦值和对焦参数峰点值之间的差值越大。
可选的，当所述当前对焦值等于所述对焦参数峰点值时，所述第一指示标志和所述第二指示标志重合。例如，在t1时刻，对焦调节组件21的调整位置在位置B，当前对焦值等于对焦参数峰点值，第二指示标志42和第一指示标志41重合。
可选的，在所述预设时间内，所述第一指示标志和所述第二指示标志在所述显示组件显示的用户界面中重合。例如，在t1时刻，当前对焦值等于对焦参数峰点值，且t1时刻之后该对焦调节组件的调整位置继续变化，t2时刻在从t1时刻开始的预设时间内，则在t1时刻到t2时刻之间，该控制装置控制对焦调节组件21停止调焦，即从t1时刻到t2时刻，尽管用户还在调整对焦调节组件21，但是对焦调节组件21已经停止调焦，即对焦调节组件21已经停止调整光学组件的焦点，保持当前对焦值等于对焦参数峰点值，则从t1时刻到t2时刻的时间内，第二指示标志42和第一指示标志41保持重合。
本实施例通过控制显示组件显示用于指示对焦参数峰点值的第一指 示标志，以及控制显示组件显示用于指示当前对焦值的第二指示标志，当第一指示标志和第二指示标志不重合时，提示用户调整对焦调节组件，以使第一指示标志和第二指示标志重合，从而使对焦参数峰点值等于当前对焦值，从而使拍摄设备可以快速准确的聚焦在目标物体上，使得用户在手动对焦时，快速准确的找到对焦对象合焦时的对焦位置。
本发明实施例提供一种手动对焦的控制方法。图5为本发明另一实施例提供的手动对焦的控制方法的流程图。如图5所示，在图1所示实施例的基础上，本实施例中的方法，还可以包括：
步骤S501、计算所述拍摄设备的显示组件显示的当前图像中多个对焦对象分别对应的对焦参数峰点值。
如图6所示，显示组件22显示的当前图像中可包括多个对焦对象，例如，对焦对象23只是该多个对焦对象中的一个，控制装置可计算该多个对焦对象中每个对焦对象在合焦时的对焦参数峰点值，可以理解，每个对焦对象在合焦时的对焦参数峰点值可以不同，也可以部分相同，也就是说，每个对焦对象可以对应一个不同的对焦参数峰点值，或者，该多个对焦对象中的部分对焦对象对应同一个对焦参数峰点值。
可选的，所述方法还包括：控制所述显示组件显示多个第一指示标志，所述多个第一指示标志用于指示所述多个对焦对象分别对应的对焦参数峰点值；控制所述显示组件显示第二指示标志，所述第二指示标志用于指示所述当前对焦值；其中，所述第一指示标志和所述第二指示标志之间的指示距离与所述第一指示标志指示的对焦参数峰点值和所述当前对焦值之间的差值相关。
如图6所示，当控制装置计算出多个对焦对象中每个对焦对象在合焦时的对焦参数峰点值后，控制显示组件22显示多个第一指示标志，该多个第一指示标志具体可以是如图6所示的第一指示标志61、第一指示标志62、第一指示标志63、第一指示标志64；第一指示标志61、第一指示标志62、第一指示标志63或第一指示标志64用于指示该多个对焦对象中至少一个对焦对象在合焦时的对焦参数峰点值。另外，该控制装置还可以控制显示组件22显示第二指示标志60，第二指示标志60用于指示对焦调节 组件21当前的调整位置对应的当前对焦值。第二指示标志60和某一个第一指示标志例如第一指示标志61之间的指示距离，与当前对焦值和第一指示标志61指示的对焦参数峰点值之间的差值相关。
如图6所示，在t0时刻，对焦调节组件21的调整位置在位置A，当前对焦值小于对焦参数峰点值，第二指示标志60位于第一指示标志61的左侧，并且第二指示标志60和第一指示标志61之间的指示距离越大，当前对焦值和第一指示标志61指示的对焦参数峰点值之间的差值越大。
可选的，当所述当前对焦值等于所述第一指示标志指示的对焦参数峰点值时，所述第一指示标志和所述第二指示标志重合。
例如，在t1时刻，对焦调节组件21的调整位置在位置B，此时，当前对焦值等于第一指示标志61指示的对焦参数峰点值，则第二指示标志60和第一指示标志61重合。
步骤S502、当所述当前对焦值等于所述多个对焦对象中至少一个对焦对象对应的对焦参数峰点值时，控制所述显示组件对所述至少一个对焦对象进行标识。
例如，第一指示标志61指示对焦对象24在合焦时的对焦参数峰点值，在t1时刻，当前对焦值等于第一指示标志61指示的对焦参数峰点值，此时，该控制装置可以控制显示组件对对焦对象24进行标识，例如，该显示组件以高亮方式显示对焦对象24，或者，以醒目的颜色例如红色框标识对焦对象24。
再例如，第一指示标志62指示对焦对象25和对焦对象26在合焦时的对焦参数峰点值，在t2时刻，对焦调节组件21的调整位置在位置C，此时，当前对焦值等于第一指示标志62指示的对焦参数峰点值，则第二指示标志60和第一指示标志62重合，并且该控制装置控制显示组件对对焦对象25和对焦对象26进行标识。
同理，如果第一指示标志63指示对焦对象27在合焦时的对焦参数峰点值，在t3时刻，对焦调节组件21的调整位置在位置D，此时，当前对焦值等于第一指示标志63指示的对焦参数峰点值，则第二指示标志60和第一指示标志63重合，并且该控制装置控制显示组件对对焦对象27进行标识。
在本实施例中，当控制装置确定当前对焦值等于某一个第一指示标志指示的对焦参数峰点值时，该控制装置还可以进一步确定该该对焦调节组件的调整位置是否继续变化，如果继续变化，则从当前对焦值等于该对焦参数峰点值对应时刻开始的预设时间内控制对焦调节组件停止调焦。
如图7所示，在t3时刻，对焦调节组件21的调整位置在位置D，此时，当前对焦值等于第一指示标志63指示的对焦参数峰点值，第二指示标志60和第一指示标志63重合，如果对焦调节组件的调整位置继续变化，例如，在t4时刻，对焦调节组件21的调整位置在位置E，t4时刻在从t3时刻开始的预设时间内，则从t3时刻到t4时刻，该控制装置控制对焦调节组件21停止调焦，保持第二指示标志60和第一指示标志63重合。
本实施例通过计算所述拍摄设备的显示组件显示的当前图像中多个对焦对象分别对应的对焦参数峰点值，当对焦调节组件的当前对焦值等于该多个对焦对象中至少一个对焦对象对应的对焦参数峰点值时，控制显示组件对该至少一个对焦对象进行标识，以提示用户该拍摄设备的光学组件完全聚焦于被标识的至少一个对焦对象，从而实现了对多个对焦对象聚焦。
本发明实施例提供一种手动对焦的控制方法。图8为本发明另一实施例提供的手动对焦的控制方法的流程图。如图8所示，在上述实施例的基础上，本实施例中的方法，可以包括：
步骤S801、获取用户对所述多个第一指示标志中任一个第一指示标志的选择操作。
如图9所示，显示组件22显示有多个第一指示标志，例如，第一指示标志61、第一指示标志62、第一指示标志63、第一指示标志64；第一指示标志61、第一指示标志62、第一指示标志63或第一指示标志64用于指示该多个对焦对象中至少一个对焦对象在合焦时的对焦参数峰点值。用户还可以选择该多个第一指示标志中的任一个第一指示标志，相应的，该控制装置获取用户对该多个第一指示标志中任一个第一指示标志的选择操作。
可选的，所述获取用户对所述多个第一指示标志中任一个第一指示标志的选择操作，包括如下几种可行的实现方式：
一种可行的实现方式是：获取用户对所述多个第一指示标志中任一个第一指示标志的点击操作。
如图9所示，用户在显示组件22上对第一指示标志63进行点击，该显示组件22具体可以是触摸屏，该触摸屏可感测到用户对第一指示标志63的点击操作，并将该点击操作发送给控制装置。
另一种可行的实现方式是：获取用户对选择按键的操作，所述选择按键用于选择所述多个第一指示标志中的任一个第一指示标志。
如图10所示，拍摄设备20还可以设置有选择按键，该选择按键可以是设置在拍摄设备20机身上的物理按键，也可以是显示在显示组件22上的虚拟按键。当用户对该选择按键进行操作时，与该选择按键对应的图标28可以在显示组件22上移动，从而使得图标28可以与多个第一指示标志中的任一个第一指示标志重合，当图标28与某一个第一指示标志例如第一指示标志63重合时，表示用户选择了第一指示标志63。
步骤S802、根据所述选择操作，控制所述对焦调节组件进行对焦。
控制装置根据用户对多个第一指示标志中任一个第一指示标志的选择操作，控制对焦调节组件21对该用户选择的第一指示标志对应的对焦对象进行对焦。例如，第一指示标志63用于指示对焦对象27在合焦时的对焦参数峰点值，当用户选择第一指示标志63时，该控制装置将根据该用户对第一指示标志63的选择操作，控制该对焦调节组件21对对焦对象27进行对焦。
另外，在一些实施例中，所述方法还包括：控制所述显示组件对所述用户选择的第一指示标志对应的至少一个对焦对象进行标识。
如图10所示，第一指示标志63用于指示对焦对象27在合焦时的对焦参数峰点值，当用户选择第一指示标志63时，该控制装置还可以控制该显示组件22对该对焦对象27进行标识，例如，该显示组件以高亮方式显示对焦对象27，或者，以醒目的颜色例如红色框标识对焦对象27。
本实施例通过控制显示组件显示用于指示多个对焦参数峰点值的多个第一指示标志，并获取用户对多个第一指示标志中任一个第一指示标志的选择操作，根据该选择操作，控制对焦调节组件对该用户选择的第一指示标志对应的对焦对象进行对焦，提高了对多个对焦对象中每个对焦对象 进行对焦的灵活性。
本发明实施例提供一种控制装置。图11为本发明实施例提供的控制装置的结构图，如图11所示，控制装置110包括：存储器111和处理器112；存储器111用于存储程序代码；处理器112，调用所述程序代码，当程序代码被执行时，用于执行以下操作：获取拍摄设备中用于手动调节的对焦调节组件当前的调整位置；根据所述对焦调节组件当前的调整位置，计算所述对焦调节组件当前的调整位置对应的当前对焦值；若所述当前对焦值等于对焦参数峰点值，且所述对焦调节组件的调整位置继续变化，则从所述当前对焦值等于所述对焦参数峰点值对应时刻开始的预设时间内控制所述对焦调节组件停止调焦。
可选的，处理器112还用于：计算所述拍摄设备的显示组件显示的当前图像中的对焦对象对应的所述对焦参数峰点值；控制所述显示组件显示第一指示标志，所述第一指示标志用于指示所述对焦参数峰点值；控制所述显示组件显示第二指示标志，所述第二指示标志用于指示所述当前对焦值；其中，所述第一指示标志和所述第二指示标志之间的指示距离与所述对焦参数峰点值和所述当前对焦值之间的差值相关。
可选的，当所述当前对焦值等于所述对焦参数峰点值时，所述第一指示标志和所述第二指示标志重合。
可选的，在所述预设时间内，所述第一指示标志和所述第二指示标志在所述显示组件显示的用户界面中重合。
可选的，处理器112还用于：计算所述拍摄设备的显示组件显示的当前图像中多个对焦对象分别对应的对焦参数峰点值；当所述当前对焦值等于所述多个对焦对象中至少一个对焦对象对应的对焦参数峰点值时，控制所述显示组件对所述至少一个对焦对象进行标识。
可选的，处理器112还用于：控制所述显示组件显示多个第一指示标志，所述多个第一指示标志用于指示所述多个对焦对象分别对应的对焦参数峰点值；控制所述显示组件显示第二指示标志，所述第二指示标志用于指示所述当前对焦值；其中，所述第一指示标志和所述第二指示标志之间的指示距离与所述第一指示标志指示的对焦参数峰点值和所述当前对焦 值之间的差值相关。
可选的，当所述当前对焦值等于所述第一指示标志指示的对焦参数峰点值时，所述第一指示标志和所述第二指示标志重合。
可选的，处理器112还用于：获取用户对所述多个第一指示标志中任一个第一指示标志的选择操作；根据所述选择操作，控制所述对焦调节组件进行对焦。
可选的，处理器112获取用户对所述多个第一指示标志中任一个第一指示标志的选择操作时，具体用于：获取用户对所述多个第一指示标志中任一个第一指示标志的点击操作。
可选的，处理器112获取用户对所述多个第一指示标志中任一个第一指示标志的选择操作时，具体用于：获取用户对选择按键的操作，所述选择按键用于选择所述多个第一指示标志中的任一个第一指示标志。
可选的，处理器112还用于：控制所述显示组件对所述用户选择的第一指示标志对应的至少一个对焦对象进行标识。
可选的，所述对焦调节组件包括如下至少一种：对焦环、调节按钮、调整轮。
本发明实施例提供的控制装置的具体原理和实现方式均与上述实施例类似，此处不再赘述。
本实施例通过获取对焦调节组件当前的调整位置，根据该对焦调节组件当前的调整位置计算所述对焦调节组件当前的调整位置对应的当前对焦值，当该当前对焦值等于对焦参数峰点值时，继续获取对焦调节组件的调整位置，以确定该对焦调节组件的调整位置是否继续变化，如果在当前对焦值等于对焦参数峰点值之后，该对焦调节组件的调整位置继续变化，则从当前对焦值等于所述对焦参数峰点值对应时刻开始的预设时间内控制所述对焦调节组件停止调焦，也就是说，在该预设时间内尽管用户还在调整对焦调节组件，但是对焦调节组件已经停止调焦，即对焦调节组件已经停止调整光学组件的焦点，保持当前对焦值等于对焦参数峰点值，从而保持对焦对象在拍摄画面中清晰可见，解决了当前对焦值等于对焦参数峰点值之后用户继续调整对焦调节组件而导致用户很难找准对焦对象合焦时的对焦位置的问题。
