Description

镜头的对焦控制方法和装置、拍摄装置 技术领域
本申请涉及镜头的控制领域，尤其涉及一种镜头的对焦控制方法和装置、拍摄装置。
背景技术
对于大多数拍摄装置来说，录像或者拍摄照片都需要对焦，从而保证被拍摄物体的清晰。
手动对焦通过手动扭动镜头上的对焦环或跟焦器，控制对焦平面的前后移动，同时通过观察屏幕上目标的清晰度、或高亮显示的峰值对焦辅助图案，来判断镜头的对焦位置是否处于被拍摄的目标上，手动对焦方式精确度较差。
自动对焦目前通过人脸识别、目标跟踪等算法的辅助，加上pdaf、TOF等测距手段，已经可以快速地将焦点锁定在特定目标的身上，实现快速抓拍清晰照片。但也正是因为自动对焦的对焦区域的选择是由算法自动选取的，在目标丢失或者需要改变对焦目标的时候，算法的表现虽然可以有不同的规则，但往往还是存在一定的随机性，与使用者的期望有差距，缺少了很多可控性。
目前缺少能够同时满足灵活性、可控性、与精准度的产品和功能出现。

具体实施方式
在每一帧都重要的影视拍摄中，自动对焦方式的不确定性和低可控性更加无法容忍，于是几乎所有的专业影视拍摄都会使用专业的“跟焦师”在MF模式下进行对焦，以达到通过焦点位置来进行创作内容表达的目的。专业的“跟焦师”需要长时间专业的训练，但因为人手准确性有限、人眼观察细节能力有限等原因，在拍摄时往往也需要提前演练准备、手动测量距离、提前做焦点位置标记等准备工作，在目标持续运动中时，还会更加困难。虽然对焦动作更加流畅，但每一帧的对焦效果并非最优，对于日益增长的画面清晰度(4k、8k等)要求来说，自动对焦是难以匹配的。
对于此，本申请根据用户的操作确定待对焦的目标对象，再根据目标对焦速度， 控制镜头由当前的对焦位置自动对焦至目标对象上，通过自动辅助算法，使得摄影录像同时可以拥有手动对焦的控制灵活性、可控性，也拥有自动对焦的准确性和易用性。

其中，在S11中、获取用户的操作，根据用户的操作确定待对焦的目标对象。
用户的操作可包括对镜头的调焦操作或对镜头拍摄的图像的触控操作。
例如，在某些实施例中，用户的操作为对镜头的手动调焦操作。在一实施例中，在对镜头进行调焦操作时，镜头基于用户的手动方式进行调焦，灵活性强，且可控性高，用户可最大程度地控制对焦目标的切换以及切换过程中焦点的动作(如调焦速度等)。具体地，对镜头的调焦操作可包括转动镜头的调焦装置，调焦装置可包括镜头的对焦环或镜头的跟焦器，但不限于此。如图2所示，用户转动镜头的对焦环20来对镜头10进行调焦；又如，用户转动镜头的调焦器来对镜头进行调焦。
可选地，目标调焦速度根据手动调焦阶段调焦装置的调焦速度得到。其中，所述手动调焦阶段调焦装置的调焦速度包括调焦装置在整个手动调焦阶段的平均调焦速度、调焦装置在第一预设时间段内的平均调焦速度或调焦装置在第一预设时间点的调焦速度。第一预设时间点包括手动调焦阶段的最后一个时间点，这可以保证在手动对焦和自动对焦进行切换时，焦点可以平滑移动到目标对象上。应当理解的是，第一预设时间段、第一预设时间点均在手动调焦阶段内。
可选地，目标调焦速度根据手动调焦阶段调焦装置的转动速度得到。其中，所 述手动调焦阶段调焦装置的转动速度包括调焦装置在整个手动调焦阶段的平均转动速度、调焦装置在第二预设时间段内的平均转动速度或调焦装置在第二预设时间点的转动速度。第二预设时间点可包括手动调焦阶段的最后一个时间点，这可以保证在手动对焦和自动对焦进行切换时，焦点可以平滑移动到目标对象上。应当理解的是，第二预设时间段、第二预设时间点均在手动调焦阶段内。
比如，根据转动速度确定目标调焦速度，可选地，目标调焦速度的大小为转动速度的大小；可选地，目标调焦速度的大小与转动速度的大小不相等。
在某些实施例中，用户的操作为对镜头拍摄的图像的触控操作，其中，触控操作包括点击操作或框选操作，但不限于此。例如，拍摄装置具有显示屏，显示屏显示镜头拍摄的图像，用户点击图像选择目标对象，或在图像中框选目标对象。本实施例中，目标调焦速度为预先设置的，可选地，在目标调焦速度预先设置后，目标调焦速度的大小可由用户重新设定；可选地，在目标调焦速度预先设置后，目标调焦速度的大小不能由用户重新设定。
下面，对S11中根据用户的操作确定待对焦的目标对象的实现过程进行说明。
本申请实施例中，镜头的对焦控制方法还可包括：获取镜头采集到的图像，对图像进行识别确定多个对象，其中，识别对象的方式可采用现有图像识别算法，本实施例的对象可包括人物、动物、车辆等拍摄时，用户感兴趣的对象。本实施例中，根据用户的操作确定多个对象中待对焦的目标对象，目标对象即为上述图像识别出的多个对象中的一个。
根据用户的操作确定多个对象中待对焦的目标对象可采用不同方式实现。
示例性的，在某些实施例中，如图3所示，根据用户的操作确定多个对象中待对焦的目标对象可包括如下步骤：
S31、根据调焦装置的转动位置，确定当前的对焦位置；
可选地，当前的对焦位置根据调焦装置的转动位置计算确定；或者，在转动调焦装置后，根据当前图像获取当前的对焦位置
S33、根据当前的对焦位置和镜头拍摄的图像中多个对象，确定多个对象中待对焦的目标对象。
可选地，根据多个对象分别和当前的对焦位置的距离确定待对焦的目标对象。
例如，在某些实施例中，目标对象为多个对象中与当前对焦位置距离最小的对象；在某些实施例中，确定多个对象中与当前对焦位置距离最小的对象；当多个对象中与当前对焦位置距离最小的对象与当前对焦位置的距离小于预设的阈值时，确定对象为待对焦的目标对象。
在某些实施例中，如图4所示，根据用户的操作确定多个对象中待对焦的目标对象可包括：
S41、根据多个对象分别和镜头的距离，确定多个对象中待对焦的目标对象，例如，可选择多个对象中，和镜头的距离最小的对象作为目标对象。多个对象分别和镜头的距离可通过拍摄装置的测距传感器如TOF(Time of flight，飞行时间)传感器检测获得，但不限于此。
在某些实施例中，如图5所示，根据用户的操作确定多个对象中待对焦的目标对象可包括：
S51、根据多个对象的失焦程度，确定多个对象中待对焦的目标对象，例如，可选择多个对象中，失焦程度最小的对象作为目标对象。
在某些实施例中，如图6所示，根据用户的操作确定多个对象中待对焦的目标对象可包括：
S61、根据多个对象的模糊度，确定多个对象中待对焦的目标对象，例如，可选择多个对象中，模糊度最小的对象作为目标对象。
应当理解的是，还可以综合考虑多个对象分别和当前的对焦位置的距离、多个对象分别和镜头的距离、多个对象的失焦程度和多个对象的模糊度中的至少两个，来确定多个对象中待对焦的目标对象。例如，可以对多个对象分别和当前的对焦位置的距离、多个对象分别和镜头的距离、多个对象的失焦程度和多个对象的模糊度中的至少两个进行加权，获得多个对象的加权值，将多个对象中，加权值最小的对象作为目标对象。
在一些实施例中，可以仅根据用户的操作来确定待对焦的目标对象；而在另外一些实施例中，镜头的对焦控制方法还可包括：对多个对象进行跟随操作，获取多个对象的跟随信息，跟随信息可包括多个对象分别和镜头的距离、多个对象的失焦程度和多个对象的模糊度中的至少一个，多个对象分别和镜头的距离可通过拍摄装置的测距传感器如TOF(Time of flight，飞行时间)传感器检测获得，但不限于此。本实施例中，根据用户的操作以及多个对象的跟随信息，确定多个对象中待对焦的目标对象。
在S12中、根据镜头的当前的对焦位置和目标调焦速度，控制镜头由当前的对焦位置自动对焦至目标对象上。
具体地，控制镜头以目标调焦速度大小由当前的对焦位置自动对焦至目标对象上，从而平滑地将镜头的焦点准确地移动到目标对象上。例如，当目标调焦速度的大小为手动调焦阶段，调焦装置的调焦速度(包括调焦装置在整个手动调焦阶段的平均调焦速度、调焦装置在第一预设时间段内的平均调焦速度或调焦装置在第一预设时间点的调焦速度)或者转动速度(包括调焦装置在整个手动调焦阶段的平均转动速度、调 焦装置在第二预设时间段的平均转动速度或调焦装置在第二预设时间点的转动速度)的大小时，这样，就可以模拟用户对调焦装置的手动操作实现自动对焦；又如，当目标调焦速度的大小为预先设置的，就可以控制镜头以预先设置的目标调焦速度大小由当前的对焦位置自动对焦至目标对象上，满足用户对调焦速度的需求。
在某些实施例中，镜头的对焦控制方法还可包括：在进行手动调焦的过程中，在镜头拍摄的图像中通过预设的标识方式标识所述目标对象。其中，所述标识方式包括高亮标识、框选标识和图案标识。可选地，在步骤S11之后，步骤S12之前，在镜头拍摄的图像中高亮目标对象，通过高亮目标对象的方式可对用户进行提示，用户可通过图像判断当前高亮的目标对象是否属于待对焦对象。镜头拍摄的图像中的目标对象被高亮的方式可根据需要选择，例如，在镜头拍摄的图像中的目标对象的中心设置高亮标识，如圆圈或其他标识。
在某些实施例中，当用户的操作停止时，根据镜头的当前的对焦位置和目标调焦速度，控制镜头由当前的对焦位置自动对焦至目标对象上，也就是，在用户的操作停止时，通过自动对焦方式对焦，从而确保对焦的像素级精准。可选地，当用户的操作停止，且目标对象在镜头拍摄的图像中被高亮时，根据镜头的当前的对焦位置和目标调焦速度，控制镜头由当前的对焦位置自动对焦至目标对象上，确保对焦的准确性。
在某些实施例中，在根据镜头的当前的对焦位置和目标调焦速度，控制镜头由当前的对焦位置自动对焦至目标对象上之后，在再次获取用户的操作之前，控制镜头持续对目标对象进行自动对焦，即在当前此获取用户的操作之后，下一次重新获取用户的操作之前，控制镜头持续地锁定目标对象进行自动对焦。
在某些实施例中，镜头的对焦控制方法还可包括：当目标对象在镜头拍摄的图像中丢失时，控制镜头的当前对焦位置保持在目标对象丢失前的位置。当目标对象丢失后，如果没有任何用户操作，则镜头的当前对焦位置会停留在目标对象丢失前的位置不做改变；如果再次获取到用户的操作，则类似于上述步骤S11～S12，用户有完全的手动对焦的控制权，自动对焦仅在用户的操作停止时接管。
本申请实施例中，自动对焦包括相位PDAF(Phase Detection Auto-focus)对焦、反差式CDAF(Contrast Detection Auto Focus)对焦或飞行时间法TOF对焦中的一种，例如，可根据镜头的当前的对焦位置和目标调焦速度，控制镜头基于相位PDAF对焦方式由当前的对焦位置自动对焦至目标对象上，或者，可根据镜头的当前的对焦位置和目标调焦速度，控制镜头基于TOF对焦方式由当前的对焦位置自动对焦至目标对象上。当然，自动对焦方式不限于上述列举的自动对焦方式，也可为其他自动对焦方式。
本申请实施例的镜头的对焦控制方法可应用于影视拍摄，如电影、电视剧等的影视拍摄，也可应用于其他类型的视频拍摄中，从而通过自动辅助算法，使得摄影录像同时可以拥有手动对焦的控制灵活性、可控性，也拥有自动对焦的准确性和易用性。
