具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明实施例中，电子设备可以包括各种具有无限通信功能的智能手机、智能手表、智能眼镜等。
图1为本发明实施例提供的一种调焦的方法的流程图。如图1所示，该调焦的方法应用于电子设备，该调焦的方法包括：
步骤101：获取参照对象的图像，其中，参照对象位于摄像头和待拍对象之间，参照对象呈第一形状，第一形状用于通过摄像头拍摄透过第一形状的待拍对象中的目标待拍对象；
步骤102：获取摄像头与参照对象之间的第一尺寸信息，以及图像中第一形状所围成区域的第二尺寸信息；
步骤103：根据第一尺寸信息和第二尺寸信息，调整摄像头的焦距。
在本发明实施例中，通过参照对象和摄像头之间的第一尺寸信息和参照对象的图像中第一形状所围成区域的第二尺寸信息，调整摄像头的焦距，不需要多次手动放大或缩小操作电子设备的屏幕，就可以实现对电子设备的焦距进行调整，整个调焦过程操作灵活，便捷，提高了用户体验。
在本发明的一些实施例中，步骤101所述的参照对象位于摄像头和待拍对象之间，参照对象呈现第一形状，该第一形状用于确定待拍对象的中的目标待拍对象，即确定待拍对象的拍照范围；其中，待拍对象为被拍摄的对象。
对应地，在该示例中，参照对象可以为预设形状的对象，例如，预设形状的手势，预设形状的纸片，预设形状的部件。下面为了描述方便，以预设形状的手势为示例。
在图2中，未变焦前图像包括多个待拍对象，位于未变焦前图像和摄像头之间的为参照对象，其中，虚拟区域中为待拍对象中的目标待拍对象。在图2中以预设形状的手势为示例。
需要说明的是，预设形状是用来确定待拍对象的拍照范围的，因此，预设形状尽量由趋近于闭合手势的形状构成，如图2中的手势。
在本发明的一些实施例中，步骤103所述的根据第一尺寸信息和第二尺寸信息，调整摄像头的焦距，可以包括：
通过摄像头和参照对象之间的第一尺寸信息，以及参照对象201所围成区域的第二尺寸信息，调整电子设备的焦距，使得调焦之后，摄像头的拍照范围为302；其中，未调焦之前拍照范围为301，如图3所示。
另外，在参照对象201所围成区域的第二尺寸信息确定时，可以通过调整参照对象201与摄像头101之间的第一尺寸信息，可以起到调整拍照范围的目的；另外，调整参照对象201所围成区域的第二尺寸信息和参照对象201与摄像头101之间的第一尺寸信息，也可以起到调整拍照范围的目的。
在本发明的一些实施例中，在调整摄像头的焦距之后，该调焦的方法还可以包括：
根据调整后的第一焦距，通过摄像头拍摄透过第一形状的目标待拍对象。
对应地，在该示例中，根据调整后的第一焦距，通过摄像头拍摄透过第一形状的目标待拍对象，可以包括：
通过触控电子设备上的按键，触发拍摄第一形状的目标待拍对象，按键为电子设备上用于拍摄图像的触控区域或电子设备上用于拍摄图像的按键；
或者，
在第一形状变化为第二形状的情况下，根据调整后的第二焦距，通过摄像头拍摄透过第二形状的目标待拍对象。
在图2中，根据调整后的焦距，通过触控电子设备上的按键或者触控区域，触发拍摄虚拟区域中的目标待拍对象。
在本发明的一些实施例中，在根据调整后的第一焦距，通过摄像头拍摄透过第一形状的目标待拍对象之前，该调焦的方法还可以包括：
将第一形状中的目标点，确定为对焦点。
对应地，在该示例中，对焦点可以为第一形状中任意一个点；例如，第一形状为圆形，对焦点可以为圆形区域的中心点。
对应地，在该示例中，第二尺寸信息为第一形状所围成区域中最大圆形的直径信息。
在本发明实施例中，识别出参照对象的第一形状的位置，绘制第一形状所围成区域的轮廓边缘图像，在绘制的边缘图像中，绘制最大圆，如图4所示。以该圆的圆心为拍摄图像的对焦点，自动调节焦距，使得摄像头拍摄的图像范围在该圆直径范围内。
在本发明实施例中，还可以通过第一形状到第二形状的变化来确定是否开始拍摄；其中，第一形状可以为超过预设值得弧形，例如3/4圆弧。第二形状为圆形，即在调焦的时候，参照对象呈现第一形状，在检测到由第一形状变化到第二形状时，拍摄透过第二形状的目标待拍对象。其中，第一形状和第二形状的尺寸信息相同，即，第一焦距和第二焦距相同。
需要说明的是，在本发明实施例中，第一形状和第二形状可以代表两 种不同的手势，以食指和拇指为示例，第一形状可以为食指和拇指围城的圆弧，是一个非闭合的区域，第二形状为食指和拇指围城的圆形，即在检测到食指和拇指闭合时，拍摄第二形状内的目标待拍对象。
对应地，如图5所示，在第一形状变化为第二形状的情况下，根据调整后的第一焦距，通过摄像头拍摄透过第一形状的目标待拍对象，可以包括：
步骤501：拍摄图像，即拍摄参考对象呈现第二形状时，参考对象的图像；
步骤502：识别指尖位置，即识别参考对象的图像中拇指和食指指尖的位置；
步骤503：确定拇指指尖与食指指尖的距离是否小于距离阈值，距离阈值可以根据电子设备的图像识别精度来进行设置。另外，在拇指指尖与食指指尖的距离小于距离阈值时，则确定第二形状为封闭的形状；
步骤504：在拇指指尖与食指指尖的距离小于距离阈值时，触发拍照，即拍摄透过第二形状的目标待拍对象。
需要说明的是，在拇指指尖与食指指尖的距离不小于距离阈值时，可以重新执行步骤502。
本发明实施例，通过调整手势的形状，就能拍摄透过第二形状的目标待拍对象，增加了趣味性，提高用户体验度。
在本发明实施例中，在调整摄像头之后，该调整的方法还可以包括：
生成第一提示信息，该第一提示信息用于提示用户拍摄目标待拍摄对象的图像。
在本发明的一些示例中，在获取参照对象的图像之后，该调焦的方法还可以包括：
生成提示信息，该提示信息用于提示用户调整第一尺寸信息和第二尺寸信息。
对应地，在该示例中，在生成提示信息之后，该调焦的方法还可以包括：
拍摄目标图像；
检测目标图像中是否存在参照对象；
在目标图像中不存在参照对象的情况下，根据调整后的第一尺寸信息和调整后的第二尺寸信息，调整摄像头的焦距。
需要说明的是，在每次调整第一尺寸信息和第二尺寸信息之后，执行步骤102，然后再获取目标图像，通过该图像检测是否将参照对象拍摄在目标图像中，如果目标图像中存在参照对象，则需要再调整第一尺寸信息和第二尺寸信息，直至拍摄的图像中不存在参考对象为止，最终根据调整之后的第一尺寸信息和第二尺寸信息，调整摄像头的焦距，以实现对目标待拍对象的拍摄。
在本发明的一些实施例中，在步骤103之后，该调焦的方法还可以包括：
存储根据调整后的第一焦距拍摄的图像。
本发明实施例，通过增加改变拇指和食指围成的手指圈的大小，达到调整焦距的目的，且结合摄像头与手指圈的距离，确定拍照范围；增加了调整焦距的趣味性，提高了用户体验度。
