随着电子设备的发展，用户使用电子设备拍摄功能的频率越来越高，用户对电子设备的拍摄画面稳定性的要求也越来越高。
目前，为避免电子设备抖动导致的拍摄画面模糊的问题，通常会采用电子防抖的方式来达到防抖效果。具体的，在电子设备采集图像的过程中，电子设备会根据固定的裁剪参数对采集的图像进行裁剪，以达到防抖效果。
然而，若按照上述的防抖方式，电子设备只能根据固定的裁剪参数对图像进行裁剪，使得电子设备防抖的灵活性差。
发明内容
本申请实施例的目的是提供一种防抖方法、防抖装置及电子设备，能够解决电子设备防抖时所存在的灵活性差的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，本申请实施例提供了一种防抖方法，该方法包括：在电子设备的摄像头实时采集第一画面的情况下，获取电子设备的抖动参数；根据与抖动参数对应的第一裁切参数；根据第一裁切参数，裁切第一画面中的第一区域，并显示裁切后的第一画面；其中，第一画面包括第一区域和第二区域，该第二区域为第一画面与N帧画面的公共区域，该N帧画面为在采集第一画面之前采集的画面，N为大于或等于1的整数。
第二方面，本申请实施例提供了一种防抖装置，该防抖装置包括：获取模块、裁切模块和显示模块；获取模块，用于在电子设备的摄像头实时采集第一画面的情况下，获取电子设备的抖动参数；裁切模块，用于根据与获取模块确定的抖动参数对应的第一裁切参数，裁切第一画面中的第一区域；显示模块，用于显示裁切模块裁切后的第一画面；其中，第一画面包括第一区域和第二区域，该第二区域为第一画面与N帧画面的公共区域，该N帧画面为在采集第一画面之前采集的画面，N为大于或等于1的整数。
第三方面，本申请实施例提供了一种电子设备，该电子设备包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的方法的步骤。

第五方面，本申请实施例提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行程序或指令，实现如第一方面所述的方法。
在本申请实施例中，首先，在电子设备的摄像头实时采集第一画面的情况下，电子设备可以获取电子设备的抖动参数。然后，电子设备可以根据与抖动参数对应的第一裁切参数，裁切第一画面中的第一区域，并显示裁切后的第一画面。其中，第一画面包括第一区域和第二区域，该第二区域为第一画面与N帧画面的公共区域，该N帧画面为在采集第一画面之前采集的画面。相比于传统的利用固定的裁切参数对画面进行裁切的方案，通过上述方案，电子设备可以根据电子设备的抖动程度灵活的获取不同的裁切参数，然后根据不同的裁切参数对第一画面中除公共区域以外的区域进行裁切，从而可以实现电子设备防抖的目的，并提高了电子设备防抖的灵活性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的防抖方法进行详细地说明。
图1为本申请实施例提供的一种防抖方法流程示意图，包括步骤201和步骤202：
步骤201：在电子设备的摄像头实时采集第一画面的情况下，电子设备获取电子 设备的抖动参数。
其中，上述的抖动参数用于指示电子设备的抖动程度。
在本申请实施例中，上述的摄像头可以为主摄像头，也可以为广角摄像头，还可以为长焦摄像头，本申请实施例对此不作限定。
在本申请实施例中，上述的第一画面可以为电子设备的前置摄像头采集的画面，也可以为电子设备的后置摄像头采集的画面，还可以为电子设备外接的摄像头采集的画面，本申请实施例对此不作限定。
在本申请实施例中，上述的第一画面可以包含目标对象，该目标对象可以包括以下至少一项：人物，风景。
在本申请实施例中，上述的抖动参数和电子设备的抖动程度间可以存在正相关关系，也可以存在负相关关系，本申请实施例对此不作限定。
可选地，在本申请实施例中，上述的抖动参数包括以下至少一项：电子设备的转动角度，电子设备的转动角速度，电子设备的转动方向，电子设备的移动速度，电子设备的移动加速度，电子设备的移动方向。
示例性的，上述的电子设备的转动角度可以为任意角度；电子设备的转动角速度可以为任意角速度；电子设备的转动方向可以为任意方向。
需要说明的是，抖动参数包括但不限于上述六种参数。例如，抖动参数还可以为电子设备通过转动角速度计算出的电子设备的转动弧长，或者可以为电子设备根据移动速度得到的位移。
在一种示例中，当抖动参数为转动角度时，转动角度和电子设备的抖动程度间可以存在正相关关系。即转动角度越大，电子设备的抖动程度越剧烈，转动角度越小，电子设备的抖动程度越轻微。
需要说明的是，上述的电子设备的转动角度、电子设备的转动角速度和电子设备的转动方向可以通过陀螺仪获取。
步骤202：电子设备根据与抖动参数对应的第一裁切参数，裁切第一画面中的第一区域，并显示裁切后的第一画面。
其中，第一画面包括第一区域和第二区域，该第二区域为第一画面与N帧画面的公共区域，该N帧画面为在采集第一画面之前采集的画面，N为大于或等于1的整数。
可以理解，该第一区域为第一画面中除第二区域以外的其他区域。
在本申请实施例中，本申请实施例中的裁切参数可以为裁切百分比，或者裁切尺寸(例如，裁切长度和宽度等)，本申请实施例对此不作限定。
在一种示例中，上述的第一裁切参数为裁切百分比，该裁切百分比可以是裁切第一画面的区域与整个第一画面的百分比，也可以是裁切后的第一画面与整个第一画面的百分比，本申请实施例对此不作限定。
在另一种示例中，上述的第一裁切参数为裁切尺寸，该裁切尺寸可以是裁切第一画面的区域的尺寸，也可以是裁切后的第一画面的尺寸，本申请实施例对此不作限定。
示例性的，当电子设备确定抖动参数后，可以根据抖动参数和裁切参数间的对应关系，确定出第一裁切参数。
其中，上述的抖动参数和裁切参数间的对应关系可以是系统默认值设置的，也可 以是用户预先设置的，本申请实施例对此不作限定。
在一种示例中，在上述的抖动参数为电子设备的转动角度的情况下，电子设备的转动角度的区间值可以对应一个裁切参数。例如，电子设备的转动角度为区间值1度至10度，对应的裁切参数可以为20％；电子设备的转动角度为区间值11度至20度，对应的裁切参数可以为25％。
示例性的，电子设备可以将第一画面和电子设备采集的第一画面之前采集的N帧画面进行比对，以获取第一画面与之前的画面的公共区域。
示例性的，上述的第一画面之前的画面可以为电子设备采集第一画面之前采集的至少一帧画面。例如，第一画面之前的画面可以为电子设备在采集第一画面之前采集的1帧画面，也可以为电子设备在采集第一画面之前采集的5帧画面。
示例性的，电子设备裁切第一画面中的第一区域可以包括：电子设备裁切第一区域中的全部或部分区域。
需要说明的是，在电子设备根据第一裁切参数裁切第一画面，会裁切到第一画面中的第二区域的情况下，电子设备可以裁切第二区域。
需要说明的是，在实际应用中，对于电子设备采集到的第一帧画面，电子设备可以不做任何处理，也可以根据默认的裁切参数对第一帧画面进行裁切，本申请实施例对此不作限定。
举例说明，在用户使用电子设备进行视频拍摄的情况下，当电子设备采集到第一帧画面时，电子设备可以使用默认的裁切参数20％对第一帧画面进行裁切，并显示裁切后的画面。然后，当用户继续使用电子设备拍摄采集到第二帧画面(即上述的第一画面)时，若电子设备确定电子设备转动了10度(即检测到电子设备发生轻微抖动)，则电子设备可以根据该抖动参数确定裁切参数为20％。接着，电子设备可以根据裁切参数20％以及第一帧画面，对第二帧画面进行裁切。此时，如图2所示，电子设备可以显示裁切后的第二帧画面31。然后，当用户继续使用电子设备拍摄采集到第三帧画面(即上述的第一画面)时，若电子设备确定电子设备转动了30度(即检测到电子设备发生剧烈抖动)，则电子设备可以根据该抖动参数确定裁切参数为30％。接着，电子设备可以根据裁切参数30％以及第二帧画面，对第三帧画面进行裁切。此时，如图3所示，电子设备可以显示裁切后的第三帧画面32。
本申请实施例提供的防抖方法，首先，在电子设备的摄像头实时采集第一画面的情况下，电子设备可以获取电子设备的抖动参数。然后，电子设备可以根据与抖动参数对应的第一裁切参数，裁切第一画面中的第一区域，并显示裁切后的第一画面。其中，第一画面包括第一区域和第二区域，该第二区域为第一画面与N帧画面的公共区域，该N帧画面为在采集第一画面之前采集的画面。相比于传统的利用固定的裁切参数对画面进行裁切的方案，通过上述方案，电子设备可以根据电子设备的抖动程度灵活的获取不同的裁切参数，然后根据不同的裁切参数对第一画面中除公共区域以外的区域进行裁切，从而可以实现电子设备防抖的目的，并提高了电子设备防抖的灵活性。
可选地，在本申请实施例中，当裁切参数过大时，可能会影响裁切后画面的可视范围，不能达到拍摄需求。因此，电子设备可以根据预设的裁切参数对画面进行裁切，以保证画面的可视范围。
示例性的，上述的步骤202中的根据与抖动参数对应的第一裁切参数，裁切第一画面中的第一区域，具体可以包括如下步骤202a：
步骤202a：电子设备在第一裁切参数大于第一预设裁切参数的情况下，根据第一预设裁切参数，裁切第一画面中的第一区域。
示例性的，上述的第一预设裁切参数可以为系统默认配置的，也可以为用户预先设置的，本申请实施例对此不作限定。
示例性的，上述的第一预设裁切参数可以称为最大裁切参数。
需要说明的是，对于不同的摄像头，上述的第一预设裁切参数可以相同，也可以不同，本申请实施例对此不作限定。
例如，在摄像头为长焦摄像头的情况下，第一预设裁切参数可以为25％；在摄像头为主摄像头的情况下，第一预设裁切参数可以为40％；在摄像头为广角摄像头的情况下，第一预设裁切参数可以为50％。
需要说明的是，当裁切参数过大时，会使得裁切后的画面中的有效画面内容过少，从而会影响画面的可视范围。
本申请提供的防抖方法可以应用于保证画面可视范围的场景中，电子设备可以设置第一预设裁切参数，由于根据第一预设裁切参数裁切的第一画面可以处于正常的可视范围，因此，当第一裁切参数大于第一预设裁切参数时，电子设备可以根据第一预设裁切参数对第一画面进行裁切，以保证画面的可视范围。
可选地，在本申请实施例中，在电子设备具有至少两个摄像头的情况下，电子设备可以利用一个摄像头采集的画面替换另一个摄像头的画面，以保证电画面的可视范围，并进一步提高电子设备的防抖效果。
示例性的，在电子设备包括第一摄像头和第二摄像头的情况下，上述的步骤202中的根据与抖动参数对应的第一裁切参数，裁切第一画面中的第一区域，具体可以包括如下步骤202b：
步骤202b：在电子设备显示第二摄像头采集的画面、且第二裁切参数大于第二预设裁切参数的情况下，电子设备根据第一裁切参数裁切第一画面中的第一区域。
其中，第一摄像头和第二摄像头用于采集同一个对象的图像，第一摄像头采集的第一画面对应的视场角大于第二摄像头采集的第二画面对应的视场角，上述的第二裁切参数为根据抖动参数确定的第二摄像头对应的裁切参数，第一裁切参数为与第一摄像头对应的裁切参数。
可以理解，第一摄像头采集的第一画面对应的视场角大于第二摄像头采集的第二画面对应的视场角，即第一画面的画面内容多于第二画面的画面内容。
示例性的，当第二摄像头为长焦摄像头时，第一摄像头可以为主摄像头或广角摄像头；当第二摄像头为主摄像头时，第一摄像头可以为广角摄像头，具体的可以根据实际需求设置，本申请实施例对此不作限定。
示例性的，第一裁切参数为与第一摄像头对应的裁切参数可以包括：第一裁切参数为与根据第二裁切参数确定的第一摄像头对应的裁切参数，或者，第一裁切参数为与根据抖动参数确定的第一摄像头对应的裁切参数。
需要说明的是，根据第二裁切参数确定的第一裁切参数与根据抖动参数确定的第 一裁切参数可以相同，也可以不同，本申请实施例对此不作限定。
在一种示例中，第一摄像头对应的预设裁切参数和第二摄像头对应的预设裁切参数(即第二预设裁切参数)可以不同。
举例说明，电子设备具有主摄像头和广角摄像头，电子设备可以利用主摄像头和广角摄像头同时采集画面。当电子设备的屏幕显示主摄像头拍摄视频画面时，若电子设备的主摄像头采集到某一画面时抖动剧烈，电子设备可以确定电子设备的转动角度为40度，并根据转动角度确定第二裁切百分比为45％。此时，由于确定的第二裁切百分比45％大于第二预设裁切参数40％，会导致主摄像头采集到某一画面裁切过多影响画面的可视性，因此，电子设备可以根据确定的主摄像头对应的第二裁切百分比45％，确定广角摄像头对应的第一裁切参数50％。然后，电子设备可以根据第一裁切参数50％对广角摄像头采集的第一画面进行裁切，最后，电子设备可以显示裁切后的广角摄像头采集的第一画面。
需要说明的是，由于广角摄像头相比于主摄像头拍摄的画面内容更多，在使用相同的裁切百分比，甚至使用比主摄像头对应的裁切百分比更大的裁切百分比时，能够保留的画面内容更多。因此，电子设备可以通过更大的裁切百分比裁切广角摄像头采集的画面，以得到与主摄像头采集的画面的画面内容相近的画面，从而可以达到平滑切换的效果，且可以保证画面的可视范围，进一步提高防抖效果。
需要说明的是，第二预设裁切参数与上述的第一预设裁切参数可以为同一参数，也可以为不同的参数，本申请实施例对此不作限定。
本申请提供的防抖方法可以应用于利用多个摄像头提升防抖效果的场景中，电子设备可以裁切拍摄画面内容更多的摄像头所拍到的画面，来替换拍摄画面内容较少的摄像头所拍到的画面，从而可以保证画面可视范围，还可以进一步提高防抖效果。
可选地，本申请实施例中，裁切参数可以由用户预先设置。
示例性的，在上述的步骤201之前，该方法还可以包括如下步骤A1和步骤A2：
步骤A1：电子设备接收用户的第一输入。
示例性的，上述的第一输入可以包括：用户针对屏幕的点击输入，或者是用户输入的语音指令，或者是用户输入的特定手势，具体的可以根据实际使用需求确定，本申请实施例对此不作限定。
本申请实施例中的特定手势可以为单击手势、滑动手势、拖动手势、压力识别手势、长按手势、面积变化手势、双按手势、双击手势中的任意一种；本申请实施例中的点击输入可以为单击输入、双击输入或任意次数的点击输入等，还可以为长按输入或短按输入。
步骤A2：响应于上述的第一输入，电子设备显示裁切参数设置界面。
其中，上述的裁切参数设置界面包括至少一个参数设置框，每个参数设置框用于设置一个裁切参数。
举例说明，如图4中的(a)所示，在电子设备显示主摄像头的预览界面33的情况下，当用户需求设置主摄像头的默认裁切参数和最大裁切参数时，可以长按“设置”按键34。此时，如图4中的(b)所示，电子设备显示裁切参数设置界面35，该裁切参数设置界面35上显示有两个参数设置框，分别为默认裁切参数和最大裁切参数。该 裁切参数设置界面35上还显示有样图，并以黑框框住，该黑框指示样图的原始显示内容。当用户在默认裁切参数设置框中输入20％，此时，电子设备显示一个虚线框36a，以提示用户裁切20％的画面后的预估显示画面内容。当用户在最大裁切参数设置框中输入35％，此时，电子设备显示一个点线框36b，以提示用户裁切35％的画面后的预估显示画面内容，如此，用户便可根据需求设置裁切参数。
示例性的，在电子设备具有至少两个摄像头的情况下，上述的裁切参数设置界面可以包括至少两个区域，其中，不同区域用于设置不同摄像头的裁切参数。
本申请提供的防抖方法可以应用于设置裁切参数的场景中，用户可以触发电子设备显示裁切参数设置界面，然后，用户可以根据需求，在裁切参数设置界面中显示的裁切参数设置框中输入裁切参数，如此，使得裁切参数的设置更灵活。
需要说明的是，本申请实施例提供的防抖方法，执行主体可以为防抖装置，或者该防抖装置中的用于执行加载防抖方法的控制模块。本申请实施例中以防抖装置执行加载防抖方法为例，说明本申请实施例提供的防抖装置。

可选地，处理器110，具体可以用于在第一裁切参数大于第一预设裁切参数的情况下，根据第一预设裁切参数，裁切第一画面中的第一区域。
可选地，在电子设备包括第一摄像头和第二摄像头，第一摄像头和第二摄像头用于采集同一个对象的图像，第一摄像头采集的第一画面对应的视场角大于第二摄像头采集的第二画面对应的视场角的情况下，处理器110，具体可以用于在电子设备显示第二摄像头采集的画面、且第二裁切参数大于第二预设裁切参数的情况下，根据第一裁切参数裁切第一画面中的第一区域；其中，第二裁切参数为根据抖动参数确定的第二摄像头对应的裁切参数，第一裁切参数为与第一摄像头对应的裁切参数。
可选地，第一摄像头对应的预设裁切参数和第二摄像头对应的预设裁切参数不同。
本申请实施例提供的电子设备，首先，在电子设备的摄像头实时采集第一画面的情况下，电子设备可以获取电子设备的抖动参数。然后，电子设备可以根据与抖动参数对应的第一裁切参数，裁切第一画面中的第一区域，并显示裁切后的第一画面。其中，第一画面包括第一区域和第二区域，该第二区域为第一画面与N帧画面的公共区域，该N帧画面为在采集第一画面之前采集的画面。相比于传统的利用固定的裁切参数对画面进行裁切的方案，通过上述方案，电子设备可以根据电子设备的抖动程度灵活的获取不同的裁切参数，然后根据不同的裁切参数对第一画面中除公共区域以外的区域进行裁切，从而可以实现电子设备防抖的目的，并提高了电子设备防抖的灵活性。
本申请实施例还提供一种可读存储介质，所述可读存储介质上存储有程序或指令，该程序或指令被处理器执行时实现上述防抖方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。

应理解，本申请实施例提到的芯片还可以称为系统级芯片、系统芯片、芯片系统或片上系统芯片等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情 况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本申请各个实施例所述的方法。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
