在本申请实施例中，“示例性地”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或者两个以上，例如，多个处理单元是指两个或者两个以上的处理单元；多个元件是指两个或者两个以上的元件等。
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拍摄控制方 法、装置和电子设备进行详细地说明。
本申请实施例提供的拍摄控制方法具体可以应用于拍摄光轨的生成过程的视频(拍摄流光快门视频)的场景，该方案中，在拍摄光轨的生成过程视频的过程中，用户可以通过对第一目标控件(至少一个第一控件中的控件，每个第一控件用于调节光轨的生成参数)的第一输入，调节光轨的生成参数，更新视频预览窗中的图像，如此，在拍摄过程中，用户可以通过输入改变光轨生成过程中的生成参数(即调节拍摄形式)，使拍摄形式多样化，从而可以解决相关技术光轨生成参数固定，拍摄形式比较单一的问题。
参考图1所示，本申请实施例提供了一种拍摄控制方法，下面以执行主体为电子设备为例，对本申请实施例提供的拍摄控制方法进行示例性地说明。该方法可以包括下述的步骤201至步骤204。
步骤201、电子设备在拍摄目标视频的过程中，显示第一界面。
其中，该目标视频为光轨的生成过程视频，第一界面包括视频预览窗和至少一个第一控件，每个第一控件用于调节光轨的生成参数。
可以理解，本申请实施例中，视频预览窗用于显示目标视频拍摄过程中实时拍摄到的预览图像(也可以称为预览画面)。
可以理解，本申请实施例中，每个第一控件可以是进度条形式的控件，也可以是按键形式的控件，还可以是其他形式的控件，本申请实施例不做限定。
可以理解，本申请实施例中，光轨的生成参数可以包括以下至少一项：同时生成的光轨数量，处于生成状态的光轨的生成速度。还可以包括其他的生成参数，本申请实施例不做限定。
可选地，该至少一个控件包括以下至少一项：数量控件，速度控件；其中，该数量控件用于调节同时生成的光轨数量，该速度控件用于调节处于生成状态的光轨的生成速度。
可以理解，上述数量控件也可以称为“同时生成数量控件”，上述速度控件也可以称为“单条生成速度控件”，本申请实施例不做限定。
可以理解，在拍摄目标视频的过程中，若不控制光轨的生成参数，则同时生成的光轨数量是不限定的，因为同时生成的光轨数量是由实际拍摄场景确定的。本申请实施例中，是通过控制目标视频的帧率来控制单条光轨的生成速度的。
步骤202、电子设备接收用户对第一目标控件的第一输入。
其中，第一目标控件为该至少一个第一控件中的控件。
可选地，第一输入可以为用户对第一目标控件的点击输入，也可以为用户对第一目标控件的拖动输入，还可以是其他的可行性输入，具体可以根据实际使用情况确定，本申请实施例不做限定。
示例性地，上述点击输入可以是单击输入、双击输入等任意次数的点击输入，也可以是短按输入或长按输入等；上述拖动输入可以是向任意方向的拖动输入，例如向上的拖动输入、向下的拖动输入、向左的拖动输入或向右的拖动输入等。
步骤203、电子设备响应于第一输入，调节与第一目标控件对应的光轨生成参数。
示例性地，若第一目标控件为数量控件，则电子设备响应于第一输入，调节同时生成的光轨数量。若第一目标控件为速度控件，则电子设备响应于第一输入，调节光轨的生成速度。
步骤204、电子设备基于调节后的光轨生成参数，更新该视频预览窗中的图像。
示例性地，用户打开相机应用程序，点击“流光快门模式”选项，进入流光快门视频拍摄模式，如图2所示，显示流光快门视频拍摄模式的界面(即第一界面)，标记“1”指示视频预览窗，视频预览窗中显示当前拍摄得到的预览图像；标记“2”指示数量控件，当前数量控件是“无限制”；标记“3”指示速度控件，当前速度控件是“50％”。用户点 击“拍摄”选项后，电子设备根据用户指定的光轨生成参数，拍摄流光快门视频(目标视频)。如果数量控件和速度控件分别是无限制和100％(即用户未设置)，则不做特殊处理，直接把拍摄得到的图像显示在视频预览窗中。如果用户通过数量控件和速度控件中的至少一个设置光轨的生成参数，则电子设备通过对拍摄得到的图像进行相应处理后，再将处理后的图像显示在视频预览窗中。
在本申请实施例中，可以通过在拍摄目标视频的过程中，显示第一界面，该目标视频为光轨的生成过程视频，第一界面包括视频预览窗和至少一个第一控件；接收用户对第一目标控件的第一输入，第一目标控件为该至少一个第一控件中的控件；响应于第一输入，调节与第一目标控件对应的光轨生成参数，并基于调节后的光轨生成参数，更新该视频预览窗中的图像。该方案中，在拍摄光轨的生成过程视频的过程中，用户可以通过对第一目标控件(至少一个第一控件中的控件，每个第一控件用于调节光轨的生成参数)的第一输入，调节光轨的生成参数，更新视频预览窗中的图像，如此，在拍摄过程中，用户可以通过输入改变光轨生成过程中的生成参数(即调节拍摄形式)，使拍摄形式多样化，从而可以解决相关技术光轨生成参数固定，拍摄形式比较单一的问题。
可选地，第一目标控件为该至少一个第一控件中的数量控件，该光轨生成参数为同时生成的光轨数量；在第一输入之前，该视频预览窗中显示第一图像；上述步骤204具体可以通过下述步骤204a实现。
步骤204a、电子设备基于第一输入，将该视频预览窗中的第一图像更新为第二图像。
其中，电子设备在未接收到第一输入的情况下，将该视频预览窗中的第一图像更新为第三图像。与第一图像相比，第二图像中有N条光轨长度增加(即说明同时生成的光轨数量为N)；与第一图像相比，第三图像中有M条光轨长度增加(即说明同时生成的光轨数量为M)；N、M均为正整数，且N、M不同。
可以理解，本申请实施例中，在第一输入之前，一段时间内拍摄到的视频片段中同时生成的光轨数量为M，则若未接收到第一输入的情况下，拍摄到的视频片段中同时生成的光轨数量为M(例如第三图像)。第一输入是用户通过对数量控件的输入，触发电子设备将后续拍摄的视频片段中同时生成的光轨数量由M调节为N的输入。电子设备响应于第一输入，获取第二图像，并将视频预览窗中的第一图像更新为第二图像。
可以理解，本申请实施例中，第二图像中除了该N条光轨，还可以包括至少一条长度停止增加的光轨，第三图像中除了该M条光轨，还可以包括至少一条长度停止增加的光轨，本申请实施例不做限定。
可选地，本申请实施例中，该N条光轨可以与该M条光轨完全不同；也可以部分相同，部分不同；若N小于M，该N条光轨可以为该M条光轨中的光轨；若N大于M，该N条光轨可以包括该M条光轨；具体可以根据实际情况确定，本申请实施例不做限定。
本申请实施例中，在第一输入之后，用户可以通过输入(例如，指定光轨具体是那些光轨的输入、或者指定是拍摄视场中哪个区域的光轨的输入等，本申请实施例不做限定)指定该N条光轨是第二图像中的哪些光轨。
本申请实施例中，用户通过第一输入调节一段时间内的视频片段中同时生成的光轨数量，从而可以使拍摄形式多样化。
可选地，本申请实施例中，在拍摄目标视频的过程中，由于拍摄场景未改变，实际拍摄得到的光轨生成图像没有改变，本申请可以通过对实际拍摄得到的图像进行与第一输入对应的处理后，得到生成参数发生变化的图像(以下称为处理后的图像)，并在视频预览窗中显示处理后的图像，并基于处理后的图像，得到目标视频。
示例性地，在上述步骤204a之前，本申请实施例提供的拍摄控制方法还可以包括下述的步骤10至步骤13。
步骤10、电子设备获取图像1(图像1为实际拍摄得到的光轨生成图像)。
步骤11、电子设备对图像1进行图像分割处理，得到S个光轨图像1，每个光轨图像1为：相对于实际拍摄的前一帧图像(实际场景中的光轨图像)中的对应光轨，光轨长度增长的光轨(图像1中的光轨)的图像，S为大于或等于P的正整数，P为M和N中的较大值。
步骤12、电子设备对第一图像进行图像分割处理，得到中间图像1，中间图像1为：从第一图像中分割出N个光轨图像2之后的图像，每个光轨图像2为：第一图像中与N条光轨中的一条光轨对应的光轨的图像。
步骤13、电子设备对中间图像1和N个光轨图像3进行图像合成处理，得到第二图像。
可选地，N个光轨图像3中的每个光轨图像3为：该S个光轨图像1中与光轨1对应的光轨图像1和之前保存的与光轨1对应的光轨图像集中，光轨长度最短的光轨图像(若N个光轨图像3中有之前保存的光轨图像，则在步骤13之后，从存储区域删除该保存的光轨图像)，其中，光轨1为N条光轨中的一条光轨，不同的光轨图像3对应N条光轨中的不同光轨。
可选地，N个光轨图像3中的每个光轨图像3为：该S个光轨图像1中与光轨1对应的光轨图像1和之前保存的与光轨1对应的光轨图像集中，任意一个光轨图像。
其中，光轨1为N条光轨中与该每个光轨图像3对应的光轨。也就是说，光轨1为N条光轨中的一条光轨，不同的光轨图像3对应N条光轨中的不同光轨。
需要说明的是：本申请实施例中，针对每条被控制生成参数(停止生成)的光轨，有一个对应的光轨图像集。针对没有被控制生成参数的光轨，可以有光轨图像集(光轨图像集为空)，也可以没有光轨图像集。一个光轨图像集可以是拍摄目标视频的初始生成的，也可以是在对应的光轨被控制生成参数的情况下才生成的，本申请实施例不做限定。
光轨图像集可以是一个集合，也可以不是一个集合(仅是一个单独的存储区域)，本申请实施例不做限定。
可选地，在步骤13之后，本申请实施例提供的拍摄控制方法还可以包括下述的步骤14。
步骤14、电子设备保存该S个光轨图像1中除与N个光轨图像3中的光轨图像相同的光轨图像1之外的光轨图像1。
示例性地，假设目标视频针对的拍摄场景中实际包括4条光轨，分别为光轨a、光轨b、光轨c和光轨d，也就是说，在不实施本申请实施例提供的拍摄控制方法的情况下，目标视频中为4条光轨的生成过程视频。在目标视频的初始的视频片段1中，4条光轨(光轨a、光轨b、光轨c和光轨d)同时生成，然后接收到用户将同时生成的光轨数量由4条减少为2条的输入1(数量控件由4调为2)，在接下来的视频片段2中，2条光轨同时生成(光轨a和光轨b)，2条光轨从接收到输入1开始停止生成(光轨c和光轨d)，将该过程中实际拍摄到的逐帧光轨生成图像中，光轨c对应的光轨图像分割出来，并逐帧保存在光轨图像集c中，光轨d对应的光轨图像分割出来，并逐帧保存在光轨图像集d中。一段时间后，接收到用户将同时生成的光轨数量由2条增加到3条的输入2(数量控件由2调为3)，在接下来的视频片段3中，2条光轨继续同时生成(光轨a和光轨b)，1条光轨(光轨c)由停止生成变为继续生成，具体地，逐帧从光轨图像集c中获取最短的光轨图像(之后从光轨图像集c删除该光轨图像)替换掉实际拍摄到的逐帧光轨生成图像中光轨c对应的光轨图像(将该替换下来的光轨图像保存至光轨图像集c)(也可以说，将从光轨图像集c中获取的逐帧最短光轨图像x与实际拍摄到的逐帧光轨生成图像中光轨c对应的光轨图像y对调)，1条光轨继续停止生成(光轨d)，将该过程中实际拍摄到的逐帧光轨生成图像中，光轨d对应的光轨图像分割出来，并逐帧保存在光轨图像集d中。又一段 时间后，接收到用户将同时生成的光轨数量由3条减少到1条的输入3(数量控件由3调为1)，在接下来的视频片段4中，1条光轨继续生成(光轨a)，2条光轨(光轨b和光轨c)由生成变为停止生成，1条光轨继续停止生成(光轨d)，将该过程中实际拍摄到的逐帧光轨生成图像中，光轨b对应的光轨图像分割出来，并逐帧保存在光轨图像集b中，光轨c对应的光轨图像分割出来，并逐帧保存在光轨图像集c中，光轨d对应的光轨图像分割出来，并逐帧保存在光轨图像集d中。
需要说明的是，本申请实施例中，在第一输入之后，未接收到其他输入(对任意第一控件的输入、停止目标视频拍摄的输入)的情况下，电子设备通过循环执行上述步骤10至步骤14，可以得到(目标视频中)第一输入之后的视频片段。
可选地，本申请实施例中，可以通过对在未接收到第一输入的情况下，得到的图像(第三图像)进行与第一输入对应的处理后，得到生成参数发生变化的图像(处理后的图像，第二图像)，并在视频预览窗中显示处理后的图像，并基于处理后的图像，得到目标视频。
示例性地，在上述步骤204a之前，本申请实施例提供的拍摄控制方法还可以包括下述的步骤204b至步骤204c。
步骤204b、电子设备获取第三图像。
步骤204c、电子设备对第三图像进行目标处理，得到第二图像。
其中，该目标处理为与第一输入对应的处理。
本申请实施例中，目标处理包括图像分割处理、图像合成处理，还可以包括其他图像处理方法，具体可以根据实际使用需求确定，本申请实施例不做限定。
可以理解，若在第一输入之前，电子设备未接收到对任意第一控件的其他输入，则第三图像是电子设备拍摄得到基于拍摄场景的实际光轨生成图像；若在第一输入之前，电子设备曾接收到对任意第一控件的其他输入，则第三图像可以是上述实际光轨生成图像，也可以是对上述实际光轨生成图像处理(与上述其他输入对应的处理)后的图像。
需要说明的是，本申请实施例中，在第一输入之后，未接收到其他输入(对任意第一控件的输入、停止目标视频拍摄的输入)的情况下，电子设备通过循环执行上述步骤204b至步骤204c，得到(目标视频中)第一输入之后的视频片段。
本申请实施例中，通过获取第三图像，并对第三图像进行目标处理，得到第二图像，从而可以得到用户需求的光轨生成图像，进而得到用户需求的光轨生成视频。
可选地，在N小于M的情况下，该M条光轨包括该N条光轨(即控制原来同时生成的光轨中的一部分光轨停止生成)，上述步骤204c具体地可以通过下述步骤101至步骤103实现。
步骤101、电子设备对第三图像进行图像分割处理，得到第一中间图像。
其中，第一中间图像为：从第三图像中分割出M-N个第一光轨图像之后的图像，每个第一光轨图像为：该M条光轨中除该N条光轨之外的一条光轨的图像。
步骤102、电子设备对第一图像进行图像分割处理，得到M-N个第二光轨图像。
其中，每个第二光轨图像为：该M条光轨中除该N条光轨之外的一条光轨的图像。
步骤103、电子设备对第一中间图像和该M-N个第二光轨图像进行图像合成处理，得到第二图像。
需要说明的是，本申请实施例中，上述图像分割处理、图像合成处理等可以参考相关图像分割技术、图像合成技术等(下同)，此处不予赘述。
可选地，上述步骤101具体地可以通过下述步骤101a实现，在步骤101a之后，本申请实施例提供的拍摄控制方法还可以包括下述的步骤104。
步骤101a、电子设备对第三图像进行图像分割处理，得到第一中间图像和M-N个第一光轨图像。
步骤104、电子设备保存该M-N个第一光轨图像。
可以理解，上述步骤101至步骤104，可以是在用户点击“拍摄”选项，开始拍摄目标视频之后，接收到的用户调节数量控件以减少同时生成光轨数量的输入(也可以是拍摄目标视频的过程中，用户多次调节数量控件之后，再次接收到的用户调节数量控件以减少同时生成光轨数量的输入)，电子设备响应于该输入，把减少的(实际)正在生成的光轨(M条光轨中除N条光轨之外的光轨)的图像通过图像分割技术提取出来(如图3所示，可以通过图像分割技术将图像的背景和前景分割开来，也可以将前景中的光轨1和光轨2分割开来。如图4所示，将光轨2分割出来保存)，然后按逐帧保存下来，供后续处理使用，在视频预览窗中该减少的(实际)正在生成的光轨停止生成。
可以理解，用户减少同时生成光轨数量的情况，如果此时实际正在生成的光轨数量大于用户设定的同时生成光轨数量，在视频预览窗中显示的图像中只包括用户设定的同时生成的光轨。那么多出来的光轨的图像可以先分割出来，并保存下来，后续当用户又设定该多出来的光轨中的一部分或全部光轨继续生成时，电子设备可以从存储区域把之前保存的该一部分或全部光轨对应的光轨图像取出来，再合成到预览图像中，在视频预览窗中进行显示，以体现该一部分或全部光轨的生成过程。
可选地，在N大于M的情况下，该N条光轨包括该M条光轨(即在原来的M条光轨继续保持生成的情况下，增加一些之前控制停止生成的光轨，重新恢复生成)，上述步骤204c具体地可以通过下述步骤105至步骤106实现。
步骤105、电子设备获取N-M个第三光轨图像。
其中，每个所述第三光轨图像为：所述第一输入之前保存的，与一条第一目标光轨对应的光轨图像集中，光轨长度最短的光轨图像；所述一条第一目标光轨为：所述N条光轨中除所述M条光轨之外的N-M条光轨中的一条光轨。
可以理解，不同的第三光轨图像对应不同的第一目标光轨。
本申请实施例中，对光轨图像集的描述可以参考上述步骤13中对光轨图像集的相关描述，此处不予赘述。
步骤106、电子设备对所述第三图像和所述N-M个第三光轨图像进行图像合成处理，得到所述第二图像。
可选地，若第三图像中除该M条光轨图像之外可以不包括其他光轨，也可以包括其他光轨。可以理解为：第三图像中除该M条光轨图像之外不包括该N-M条光轨(第三图像中不包括该N-M条光轨)，第三图像中除该M条光轨图像之外包括该N-M条光轨(第三图像中包括该N-M条光轨)，第三图像中除该M条光轨图像之外包括该N-M条光轨中的一部分光轨(第三图像中包括该N-M条光轨中的一部分光轨)。针对，N-M条光轨中不在第三图像中的光轨，步骤106中的合成处理可以为将该不在第三图像中的光轨对应的第三光轨图像插入第三图像中的相应位置；针对，N-M条光轨中在第三图像中的光轨，步骤106中的合成处理可以为用该不在第三图像中的光轨对应的第三光轨图像替换第三图像中的相应位置的光轨图像。
可选地，在第三图像中包括该N-M条光轨的情况下，上述步骤106具体也可以通过下述步骤106a至步骤106b实现。
步骤106a、电子设备对第三图像进行图像分割处理，得到第二中间图像。
其中，第二中间图像为：从第三图像中分割出N-M个第五光轨图像之后的图像，每个第五光轨图像为：该N条光轨中除该M条光轨之外的一条光轨的图像。
可以理解，一个第五光轨图像对应一个第三光轨图像，不同的第五光轨图像对应不同的第三光轨图像。该光轨图像集中的每个光轨图像中的光轨的长度均大于对应的第五光轨图像中的光轨的长度。因为第五光轨图像为：第三图像中长度未增长的一条光轨的图像， 而该光轨图像集中保存的光轨图像都是实际长度增长，但未显示在视频预览窗中的光轨图像。
步骤106b、电子设备对第二中间图像和该N-M个第三光轨图像进行图像合成处理，得到第二图像。
可以理解，上述步骤105至步骤106是在用户减少同时生成的光轨数量之后，有一定数量缓存起来的光轨图像之后，又提高同时生成的光轨数量(将原来控制停止生成的光轨中的一部分或全部光轨又恢复生成)。此时由于有缓存的光轨，当提高光轨同时生成数量以后，可以将该一部分或全部光轨的实时生成图像分割出来并保存起来，然后将之前保存的对应光轨图像提取出来，合成到预览图像中，显示在视频预览窗中，也就是说，会在视频预览窗上显示大量之前缓存的光轨图像。
可选地，第一界面中还包括至少一个第二控件，每个第二控件用于确定该N-M个第三光轨图像的分布模式，上述步骤105之前，本申请实施例提供的拍摄控制方法还可以包括下述的步骤107至步骤108，上述步骤105具体可以通过下述步骤105a实现。
步骤107、电子设备接收用户对第二目标控件的第二输入。
其中，第二目标控件为该至少一个第二控件中的控件。
可选地，该至少一个第二控件包括以下至少一项：单点扩散分布控件，多点扩散分布控件，均匀分布控件，随机分布控件。
示例性地，该至少一个第二控件包括：单点扩散分布控件、多点扩散分布控件、均匀分布控件、随机分布控件，分别对应图2中的标记“4”指示的“单点扩散”、“多点扩散”、“均匀”、“随机”。
可以理解，本申请实施例中，如图5中的(a)所示，单点扩散分布控件用于控制恢复生成的光轨是围绕一个中心点分布的(即优先选取靠近中心点的光轨恢复生成，然后选取远离中心点的光轨恢复生成)。如图5中的(b)所示，多点扩散分布控件用于控制恢复生成的光轨是分别围绕多个中心点分布的(即优先选取任意靠近两个中心点的光轨恢复生成，然后选取任意远离两个中心点的光轨恢复生成)。如图6中的(a)所示，均匀分布控件用于控制恢复生成的光轨是在图像中均匀分布的，不要集中于任意一点或多点分布。如图6中的(b)所示，随机分布控件用于控制恢复生成的光轨是在图像中随机分布的，不限制其分布形式。
步骤108、电子设备响应于第二输入，确定该N-M个第三光轨图像的分布模式为目标模式。
步骤105a、电子设备响应于第二输入，从K个第四光轨图像中获取分布模式为目标模式的N-M个第四光轨图像，作为该N-M个第三光轨图像。
其中，每个第四光轨图像为：第一输入之前保存的，与一条第二目标光轨对应的光轨图像集中，光轨长度最短的光轨图像，一条第二目标光轨为除M条光轨之外的一条光轨，K为大于N-M的正整数。
可以理解，不同的第四光轨图像对应不同的第二目标光轨。
示例性地，如图4所示，当用户选择“单点扩散”选项时，如图7所示，响应于用户输入，电子设备控制恢复生成的光轨围绕用户指定的中心点向外扩散分布。若用户不选择任意一个第二控件，则电子设备可以按照原来的顺序(光轨出现时间的先后顺序)依次分布。
本申请实施例中，增加至少一个第二控件，用户可以根据自身需求选择对应的第二控件，以使恢复生成的光轨是按照用户需求分布的，从而可以增加拍摄形式。
可选地，第一目标控件为该至少一个第一控件中的速度控件，该光轨生成参数为光轨的生成速度，该速度控件用于调节处于生成状态的光轨的生成速度；上述步骤204具体可 以通过下述步骤204d实现。
步骤204d、电子设备在第一时间段内，以第一帧率更新该视频预览窗中的图像。
其中，第一时间段的起始时刻为接收到第一输入的时刻，第一时间段的结束时刻为接收到目标输入的时刻，该目标输入为以下任意一项：对该至少一个第一控件中的控件的输入，停止拍摄该目标视频的输入。
第一帧率是基于第一输入确定的，在未接收到第一输入的情况下，以第二帧率更新该视频预览窗中的图像；第二帧率与第一帧率不同。
可以理解，本申请实施例中，用户通过对速度控件的第一输入，调整了视频的帧率，从而可以改变光轨的生成速度。若降低帧率，则降低光轨的生成速度，若提高帧率，则提高光轨的生成速度。如此，可以增加拍摄形式。
可选地，在第一帧率小于第二帧率的情况下(即降低帧率)，在上述步骤204d之后，本申请实施例提供的拍摄控制方法还可以包括下述的步骤205。
步骤205、电子设备保存第一目标图像。
第一目标图像为第一时间段内，未在该视频预览窗中更新的图像。
可以理解，本申请实施例中，若降低帧率，则有一部分生成的视频片段(即第一目标图像，本申请实施例中，不限定第一目标图像中的图像数量)无法在视频预览窗中显示，电子设备可以先将第一目标图像保存起来，以待后续提高帧率时使用。
本申请实施例中，降低帧率即延缓光轨的生成速度。具体地，如图8所示，电子设备可以将获得的预览图像保存下来，然后按照F*(X％)帧每秒的速度在视频预览窗中显示。其中，X％为用户设定的速度控件的值，F帧每秒为第一输入之前的帧率。
可选地，在第一帧率大于第二帧率的情况下(即提高帧率)，在上述步骤204d之前，本申请实施例提供的拍摄控制方法还可以包括下述的步骤206，上述步骤204d具体可以通过下述步骤204d1实现。
步骤206、电子设备获取第二目标图像，第二目标图像为：第一输入之前，保存的未在该视频预览窗中更新的图像。
步骤204d1、电子设备在第一时间段内，基于第二目标图像和第三目标图像，以第一帧率更新该视频预览窗中的图像。
其中，第三目标图像为：第一时间段内生成的图像。
本申请实施例中，在之前用户通过降低速率的输入延缓光轨的生成速度的前提下，本步骤才可以通过提高帧率的方法加快光轨的生成速度，甚至使光轨的生成速度高于实际生成速度(高于F帧每秒)。具体地，(如图9所示)，电子设备把当前生成的图像逐帧保存下来，然后把之前逐帧缓存下来的图像以F*(Y％)帧每秒的速度重新在视频预览窗中显示。其中，其中，Y％为用户设定的速度控件的值。
可选地，用户还可以通过点击“停止拍摄”按钮，结束拍摄，并生成目标视频。具体地，用户可以手动停止视频录制，电子设备把录制出来的视频保存到本地，供用户查看。
本申请实施例中，在拍摄光轨生成过程的视频的过程中，在电子设备相机的流光快门视频模式下，用户可以通过对速度控件的输入调节光轨的生成速度，以使光轨延缓生成或加快生成。
需要说明的是，本申请实施例提供的拍摄控制方法，执行主体可以为拍摄控制装置，或者该拍摄控制装置中的用于执行拍摄控制方法的功能模块和/或功能实体。本申请实施例中以拍摄控制装置执行拍摄控制方法为例，说明本申请实施例提供的拍摄控制方法的装置。
