基于上述移动终端硬件结构以及通信网络系统，提出本申请各个实施例。
在相关技术中，终端设备中的摄像镜头使用定焦镜头，以降低终端设备的成本，而安装定焦镜头的终端设备不具备自动对焦的功能，在用户使用安装定焦镜头的终端设备进行拍摄时，用户通过经验判断拍摄图像的清晰度。例如，用户可以通过调整手机与拍摄对象之间的物距，以改变屏幕中图像的清晰度，在用户观察到清晰度合适的时候，用户点击拍照按键得到图像。但是，用户通过经验观察图像的清晰度，使得拍摄的图像的清晰度较低(微距拍摄时用户观察的图像的清晰度可能不是清晰度最好的图像)，进而导致拍摄的效果较差。
为了解决相关技术中拍摄的效果较差的技术问题，本申请实施例提供一种摄像控制方法，获取摄像设备对目标对象连续采集的至少两张图像，可选地，摄像设备的摄像镜头为定焦镜头，获取至少两张图像的清晰度，根据至少两张图像的清晰度，确定摄像设备当前的清晰度状态，可选地，清晰度状态为升高状态、降低状态、位于最高范围状态，根据摄像设备当前的清晰度状态，控制摄像设备对目标对象进行图像拍摄。在上述方法中，在使用定焦镜头的摄像设备拍摄图像时，由于摄像设备可以准确的获取多张图像的清晰度，因此，通过多张图像的清晰度，可以准确的确定清晰度较好的图像，进而提高拍摄的效果。
为了便于理解，下面，结合图3，介绍本申请的应用场景。
图3为本申请实施例提供的一种应用场景示意图。请参见图3，包括摄像设备和目标对象。可选地，摄像设备拍摄功能已开启。在摄像设备与目标对象的距离较远时，摄像设备的屏幕中显示的目标对象的图像较为模糊。在摄像设备向目标对象移动时，摄像设备与目标对象之间的物距发生改变，摄像设备屏幕中显示的目标对象的图像的清晰度发生变化。在摄像设备向目标对象移动的过程中，摄像设备获取多张目标对象的图像，并在多张目标对象的图像中确定清晰度最高的图像作为拍摄的图像。这样，在摄像设备的镜头为定焦镜头时，摄像设备可以根据图像的清晰度，确定拍摄的图像，进而提高拍摄的效果。
下面，通过具体实施例对本申请所示的技术方案进行详细说明。可选地，如下实施例 可以单独存在，也可以相互结合，对于相同或相似的内容，在不同的实施例中不再重复说明。
图4为本申请实施例提供的一种摄像控制方法的流程示意图。请参见图4，该方法可以包括：
S11、获取摄像设备对目标对象连续采集的至少两张图像。
本申请实施例的执行主体可以为移动终端，也可以为设置在移动终端中的摄像控制装置。可选地，摄像控制装置可以通过软件实现，也可以通过软件和硬件的结合实现。
可选地，摄像设备为任意具有摄像功能的设备。例如，摄像设备可以为相机、手机、平板电脑等设备。摄像设备的摄像镜头为定焦镜头。可选地，定焦镜头为只有一个固定焦距的镜头。在实际应用过程，若摄像设备的镜头为定焦镜头，则摄像设备无法自动对焦。
目标对象为摄像设备的拍摄对象。例如，若摄像设备拍摄水杯，则目标对象为水杯；若摄像设备拍摄桌子，则目标对象为桌子。
可选地，在摄像设备打开拍摄功能时，摄像设备可以实时的获取包括目标对象的图像。例如，在手机打开拍摄功能时，手机可以获取镜头拍摄的每一帧的图像。可选地，在摄像设备打开拍摄功能时，摄像设备可以连续获取多张包括目标对象的图像，
S12、获取至少两张图像的清晰度。
清晰度用于指示图像的聚焦值的大小。例如，图像的聚焦值越大，图像的清晰度越高，图像的聚焦值越小，图像的清晰度越低。可选地，可以通过预设模型，得到至少两张图像的清晰度。可选地，预设模型为对多组样本学习得到的，每组样本包括样本图像和样本清晰度。
多组样本可以为预先标记的样本。例如，对于样本图像1，获取样本图像1对应的样本清晰度1，得到一组样本，该组样本包括样本图像1和样本清晰度1。采用该种方式，可以得到多组样本。例如，多组样本可以如表1所示：
表1
多组样本 样本图像 样本清晰度
第一组样本 样本图像1 样本清晰度1
第二组样本 样本图像2 样本清晰度2
第三组样本 样本图像3 样本清晰度3
…… …… ……
需要说明的是，表1只是以示例的形式示意多组样本，并非对多组样本的限定。
例如，若输入预设模型中的图像与样本图像1相同，则该图像对应的清晰度为样本清晰度1；若输入预设模型中的图像与样本图像2相同，则该图像对应的清晰度为样本清晰度2；若输入预设模型中的图像与样本图像3相同，则该图像对应的清晰度为样本清晰度3。
可选地，在摄像设备的拍摄页面中实时的显示图像对应的清晰度。例如，在拍摄页面中显示图像时，拍摄页面的预设区域中显示图像对应的清晰度，进而使得用户可以准确的确定当前拍摄图像时图像对应的清晰度。
可选地，在摄像设备的镜头为定焦镜头时，摄像设备拍摄的图像的清晰度和摄像设备与目标对象之间的物距相关。
下面，结合图5，对图像的清晰度和物距之间的关系进行说明。
图5为本申请实施例提供的一种图像清晰度与物距之间的关系示意图。请参见图5，包括清晰度与物距之间的关系坐标系。可选地，坐标系的横轴为摄像设备与目标对象之间的物距，坐标系的纵轴为摄像设备获取的图像对应的清晰度。
请参见图5，在摄像设备与目标对象的物距增加的过程中，摄像设备获取的图像的清晰度先升高再下降，坐标系中的最高点为摄像设备获取的图像的清晰度最高。在实际应用过程中，摄像设备可以获取镜头采集的每一帧图像，并确定每一帧图像对应的清晰度。
S13、根据至少两张图像的清晰度，控制摄像设备对目标对象进行图像拍摄。
可以根据如下可行的实现方式，控制摄像设备对目标对象进行图像拍摄：根据至少两张图像的清晰度，确定摄像设备的清晰度状态。可选地，清晰度状态为升高状态、降低状态、位于最高范围状态。
升高状态用于指示摄像设备当前拍摄的图像的清晰度正在升高。例如，在用户移动摄像设备时，若摄像设备的屏幕中显示的图像的清晰度在上升，则摄像设备当前的清晰度状态为升高状态。
降低状态用于指示摄像设备当前拍摄的图像的清晰度正在下降。例如，在用户移动摄像设备时，摄像设备与拍摄的目标对象之间的物距发生改变，若摄像设备的屏幕中显示的图像的清晰度在下降，则摄像设备当前的清晰度状态为下降状态。
位于最高范围状态用于指示摄像设备当前拍摄的图像的清晰度在最高清晰度的预设区间内。可选地，预设区间为预先设置的数值。例如，若图像的最高清晰度为100，预设区间为10，则在摄像设备拍摄的图像的清晰度为90-100时，摄像设备的状态为位于最高范围状态。例如，在用户移动摄像设备时，摄像设备与拍摄的目标对象之间的物距发生改变，若摄像设备的屏幕中显示的图像的清晰度在最高清晰度的预设范围内，则摄像设备当前的清晰度状态为位于最高范围状态。
可选地，摄像设备可以包括多个清晰度状态。例如，摄像设备可以同时出现升高状态和位于最高范围状态，或者，摄像设备可以同时出现降低状态和位于最高范围状态。
可选地，以摄像设备连续获取的四张图像为例，在确定清晰度状态时有如下2种情况：
情况1：摄像设备向一个方向移动。
在摄像设备持续向一个方向移动时，若第一张图像的清晰度低于第二张图像的清晰度，第二张图像的清晰度低于第三张图像的清晰度，第三张图像的清晰度低于第四张图像的清晰度，则确定摄像设备的清晰度状态为升高状态。例如，在摄像设备朝向目标对象移动时，摄像设备连续获取的四张图像的清晰度依次升高，则说明摄像设备当前的清晰度状态为升高状态。
在摄像设备持续向一个方向移动时，若第一张图像的清晰度高于第二张图像的清晰度，第二张图像的清晰度高于第三张图像的清晰度，第三张图像的清晰度高于第四张图像的清晰度，则确定摄像设备的清晰度状态为降低状态。例如，在摄像设备朝向目标对象移动时，摄像设备连续获取的四张图像的清晰度依次下降，则说明摄像设备当前的清晰度状态为降低状态。
摄像设备获取的图像的清晰度先升高再下降，则摄像设备在向目标对象移动的过程中，在清晰度最高值的预设区间内的清晰度对应的摄像设备的清晰度状态为位于最高范围状态。例如，在摄像设备向远离目标对象或者朝向目标对象移动时，若第一张图像的清晰度小于第二张图像的清晰度，则摄像设备获取第一张图像和第二张图像时，摄像设备的清晰度状态为升高状态，若第二张图像的清晰度大于第三张图像的清晰度，第三张图像的清晰度大于第四张图像的清晰度，则摄像设备获取第三张图像和获取第四张图像时，摄像设备的清晰度状态为降低状态，此时，可以确定摄像设备获取的第三张图像的清晰度最高，在第三张图像的清晰度的预设区间内的清晰度对应的摄像设备的清晰度状态为位于最高范围状态。
情况2：摄像设备向多个方向移动。
在摄像设备向多个方向移动时，若摄像设备朝向目标对象移动时，清晰度持续升高，则摄像设备背向目标对象移动时清晰度降低，若摄像设备朝向目标对象移动时清晰度持续 降低，则摄像设备背向目标对象移动时清晰度升高。因此，在摄像设备向多个方向移动时，在摄像设备的清晰度状态由上升状态变为下降状态时，并不能确定摄像设备的清晰度状态为位于最高范围状态。
下面，结合图6，对摄像设备的清晰度状态为位于最高范围状态进行详细说明。
图6为本申请实施例提供的一种清晰度状态为位于最高范围状态的示意图。请参见图6，包括清晰度与物距之间的关系坐标系。可选地，坐标系的横轴为摄像设备与目标对象之间的物距，坐标系的纵轴为摄像设备获取的图像对应的清晰度。
请参见图6，在摄像设备与目标对象的物距增加的过程中，摄像设备获取的图像的清晰度升高，在摄像设备获取的图像的清晰度达到最高点时，摄像设备获取的图像的清晰度下降，在最高点的预设范围内，摄像设备的清晰度状态都为位于最高范围状态，在摄像设备的清晰度状态为位于最高范围状态时，摄像设备拍摄的图像的清晰度较高。
根据摄像设备当前的清晰度状态，控制摄像设备对目标对象进行拍摄。可选地，可以根据如下可行的实现方式，控制摄像设备对目标对象进行图像拍摄：根据摄像设备当前的清晰度状态，判断至少两张图像中是否存在目标图像。其中目标图像的清晰度为预设清晰度。可选地，预设清晰度可以为最高清晰度。例如，目标图像的清晰度为摄像设备可以拍摄的最高的清晰度。
可选地，可以根据如下可行的实现方式，判断至少两张图像中是否存在目标图像：若摄像设备当前的清晰度状态为降低状态，且摄像设备的历史清晰度状态中存在位于最高范围状态，则确定至少两张图像中存在目标图像。可选地，历史清晰度状态为当前时刻之前摄像设备的清晰度状态。例如，在当前时刻之前摄像设备的清晰度状态包括升高状态和位于最高范围状态，则历史清晰度状态包括升高状态和位于最高范围状态。
在实际应用过程中摄像设备当前的清晰度状态为下降状态，说明摄像设备在当前时刻获取的图像的清晰度比上一时刻获取的图像的清晰度低，若摄像设备在本次摄像过程中存在清晰度状态为位于最高范围状态的情况，则说明摄像设备在本次摄像过程获取的多张图像中包括清晰度最高的目标图像。
在确定至少两种图像中存在目标图像时，将目标图像存储至摄像设备。例如，摄像设备在本次拍摄的过程中获取多张图像，若多张图像中包括清晰度最高的目标图像，则将目标图像存储至摄像设备。
本申请实施例提供一种摄像控制方法，可选地，摄像设备的摄像镜头为定焦镜头，获取摄像设备对目标对象连续采集的至少两张图像，根据预设模型，获取至少两张图像的清晰度，并根据至少两张图像的清晰度，确定摄像设备当前的清晰度状态，可选地，清晰度状态为升高状态、降低状态和位于最高范围状态，根据摄像设备当前的清晰度状态，判断至少两张图像中是否存在清晰度为预设清晰度的目标图像，在确定至少两张图像中存在目标图像时，将目标图像存储至摄像设备。在上述方法中，在使用定焦镜头的摄像设备拍摄图像时，由于摄像设备可以准确的获取多张图像的清晰度，并根据多张图像的清晰度，确定摄像设备的清晰度状态，进而可以根据摄像设备的清晰度状态，准确的判断多张图像中是否存在清晰度最高的图像，这样可以将清晰度最高的图像存储至摄像设备中，进而提高定焦摄像设备拍摄的效果。

S72、在摄像设备的拍摄页面中显示摄像设备当前的清晰度状态对应的指示信息。
指示信息用于指示摄像设备的清晰度状态。可选地，指示信息可以为上升箭头、下降箭头或拍摄框。
可选地，可以根据如下可行的实现方式，在摄像设备的拍摄页面中显示指示信息：若摄像设备当前的清晰度状态为升高状态，则确定指示信息为上升箭头。例如，若摄像设备的清晰度状态为升高状态，则可以在摄像设备的拍摄页面中的预设窗口生成上升箭头，进而使得用户通过上升箭头确定摄像设备当前的清晰度状态为升高状态。
若摄像设备当前的清晰度状态为降低状态，则确定指示信息为下降箭头。例如，若摄像设备的清晰度状态为降低状态，则可以在摄像设备的拍摄页面中的预设窗口生成下降箭头，进而使得用户通过下降箭头确定摄像设备当前的清晰度状态为降低状态。
若摄像设备当前的清晰度状态为位于最高范围状态，则确定指示信息为拍摄框。例如，若摄像设备的清晰度状态为位于最高范围状态，则可以在摄像设备的拍摄页面中的预设窗口生成绿色的拍摄框，进而使得用户通过绿色的拍摄框确定摄像设备当前的清晰度状态为位于最高范围状态。
下面，结合图8A-图8C，详细介绍摄像设备显示指示信息的过程。
图8A为本申请实施例提供的一种显示指示信息的过程示意图。请参见图8A，包括摄像设备和目标对象。摄像设备的拍摄页面中可以显示包括目标对象的图像。在摄像设备向目标对象移动时，摄像设备的清晰度状态为升高状态。
请参见图8A，在摄像设备的清晰度状态为升高状态时，在摄像设备的拍摄页面的预设区域中生成上升箭头，进而使得用户通过上升箭头，准确的确定摄像设备当前的清晰度状态为升高状态，提高拍摄的效果。
图8B为本申请实施例提供的另一种显示指示信息的过程示意图。请参见图8B，包括摄像设备和目标对象。摄像设备的拍摄页面中可以显示包括目标对象的图像。在摄像设备向背离目标对象的方向移动时，摄像设备的清晰度状态为降低状态。
请参见图8B，在摄像设备的清晰度状态为降低状态时，在摄像设备的拍摄页面的预设区域中生成下降箭头，进而使得用户通过下降箭头，准确的确定摄像设备当前的清晰度状态为下降状态，提高拍摄的效果。
图8C为本申请实施例提供的另一种显示指示信息的过程示意图。请参见图8C，包括摄像设备和目标对象。摄像设备的拍摄页面中可以显示包括目标对象的图像。在摄像设备向目标对象的方向移动时，摄像设备的清晰度状态存在位于最高范围状态。

本申请实施例提供一种摄像控制方法，确定摄像设备当前的清晰度状态，在摄像设备的拍摄页面中显示摄像设备当前的清晰度状态对应的指示信息，可选地，指示信息包括上升箭头、下降箭头和拍摄框。在上述方法中，在摄像设备的清晰度状态发生变化时，摄像设备的拍摄页面的预设区域中可以显示对应的指示信息，这样用户可以根据拍摄页面中的指示信息，准确的确定摄像设备的清晰度状态，进而提高拍摄的效果。
在上述任意一个实施例的基础上，在摄像设备获取目标图像之后，用户也可以主动拍摄图像，本申请还包括对拍摄图像的处理过程。下面，结合图9，详细介绍对拍摄图像进行处理的过程。
图9为本申请实施例提供的一种对拍摄图像的处理过程的示意图。请参见图9，该方法包括：
S91、响应于拍摄指令，获取拍摄指令对应的拍摄图像。
可选地，拍摄指令可以为用户对拍摄页面中的拍摄按键的点击操作。拍摄指令对应的拍摄图像可以为摄像设备接收到拍摄指令时，拍摄页面中显示的图像。例如，拍摄指令对应的拍摄图像为在用户点击拍摄页面中的拍摄按键时，摄像设备的拍摄页面中显示的图像。
下面，结合图10，详细说明摄像设备获取拍摄指令对应的拍摄图像的过程。

S92、根据目标图像的清晰度和拍摄图像的清晰度，对拍摄图像进行处理。
可选地，可以根据如下可行的实现方式对拍摄图像进行处理：
若目标图像的清晰度与拍摄图像的清晰度相同，则删除拍摄图像。例如，若摄像设备获取的目标图像的清晰度与用户点击拍摄按键获取的图像的清晰度相同，则摄像设备只需保存一张图像即可，此时，摄像设备可以删除拍摄指令对应的拍摄图像，摄像设备也可以删除目标图像。
和/或，若目标图像的清晰度与拍摄图像的清晰度不相同，则在摄像设备中存储拍摄图像。例如，在摄像设备获取的目标图像的清晰度与用户点击拍摄按键获取的图像的清晰度不相同时，由于目标图像的清晰度为最高清晰度，因此，拍摄指令对应的拍摄图像的清晰度小于目标图像的清晰度，此时可以将拍摄指令对应的拍摄图像存储至摄像设备中，这样可以保证用户使用摄像设备拍摄的功能，提高摄像设备拍摄的灵活度，进而提高摄像设备拍摄的效果。
本申请实施例提供一种摄像控制方法，在摄像设备获取目标图像之后，响应于拍摄指令，获取拍摄指令对应的拍摄图像，根据目标图像的清晰度和拍摄图像的清晰度，对拍摄图像进行处理。这样，在目标图像的清晰度和拍摄图像的清晰度相同时，摄像设备删除拍摄图像，进而节省内存空间，在拍摄图像的清晰度与目标图像的清晰度不同时，在摄像设备中保存拍摄图像，进而在不影响主动拍摄功能的前提下，提高拍摄的灵活度，并提高拍摄的效果。
在上述任意一个实施例的基础上，下面，结合图11，对上述摄像控制方法的过程进行说明。
图11为本申请实施例提供的一种摄像控制方法的过程示意图。请参见图11，包括摄像设备和目标对象。在摄像设备向目标对象移动时，摄像设备连续获取至少两张图像，并根据至少两张图像的清晰度，确定摄像设备的清晰度状态。
请参见图11，在摄像设备的清晰度状态为升高状态时，在摄像设备的预设窗口生成上升箭头。在摄像设备继续向目标对象移动时，摄像设备获取图像的清晰度升高至最高清晰度的预设区间范围，此时，摄像设备的清晰度状态为位于最高范围状态，摄像设备的拍摄页面的预设窗口中生成拍摄框，在摄像设备获取的图像的清晰度升高至最高的清晰度时，摄像设备存储最高清晰度的图像。
请参见图11，在摄像设备继续向目标对象移动时，摄像设备获取图像的清晰度下降，此时摄像设备的清晰度状态为下降状态，摄像设备的拍摄页面的预设窗口中生成下降箭头。这样，在安装定焦摄像头的摄像设备拍摄图像时，在摄像设备移动过程中，摄像设备可以获取图像的清晰度，并根据图像的清晰度确定摄像设备的清晰度状态，进而根据摄像设备的清晰度状态，确定清晰度最高的目标图像，并保存清晰度最高的目标图像，这样可以提高摄像设备的拍摄效果。
