具体实施方式
以下结合附图及实施例，对本公开进行详细说明。此处描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
本公开实施例提供的视频生成方法，可以应用于多类终端设备，可以但不限于是多种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。
如图1所示，该终端设备10可以包括处理器11、存储器12、系统总线13、显示屏幕14，以及视频录制装置15；其中，处理器11、存储器12、显示屏幕 14和视频录制装置15可以通过系统总线13连接。存储器12可以包括非易失性存储介质和/或易失性存储介质，可以存储计算机程序；处理器11执行该计算机程序时可以实现本公开实施例提供的一种视频画面调整方法；显示屏幕14可以是液晶屏、电子墨水屏，设置为显示录制视频和参考视频；视频录制装置15可以是摄像头等，设置为录制视频。该终端设备还可以支持多类应用程序，例如用于分屏录制的应用程序。
本领域技术人员可以理解，图1中示出的结构，仅仅是与本公开方案相关的部分结构的框图，并不构成对本公开方案所应用于上述终端设备的限定，实际的终端设备可以包括比图中所示更多或更少的部件，或者组合某些部件，或者具有不同的部件布置。
在一个实施例中，如图2所示，提供了一种视频画面调整方法，以该方法应用于图1中的终端设备为例进行说明，可以包括以下步骤：
步骤202，将参考视频的画面的第一高宽比和预设高宽比进行比较，得到第一比较结果。
其中，上述参考视频为终端设备中存储的完整视频，可以是预先存储的视频、预先录制的视频，还可以是通过网络下载的视频等等。其中，预设高宽比对应的人眼舒适参数满足预设条件，该预设条件可以理解为预设高宽比对应的人眼舒适参数最优。在一实施例中，人眼舒适参数最优可以理解为该人眼舒适参数所属的舒适程度最高，即不同视频的画面的高宽比可以对应不同的人眼舒适参数。例如，预设高宽比可以通过统计用户针对大量分屏录制的合成视频的观看评价来得到。该分屏录制的合成视频包括录制视频和参考视频，不同的合成视频中录制视频的高宽比可以不同；例如，采用用户评价最高的录制视频的高宽比作为预设高宽比。示例性地，预设高宽比可以为3:4、4:5、1:1、5:4、4:3或5:3等，还可以是其它高宽比。
在一个实施例中，终端设备通过统计大量已录制的视频的高宽比，获得针对已录制的视频的高宽比的统计参数作为预设高宽比，该统计参数可以是均值，还可以是中位值，还可以是其它统计参数。在一实施例中，上述预设高宽比和终端设备的类型还存在相关性；例如，针对手机的预设高宽比和针对个人计算机的预设高宽比是不同的。因此在一个实施例中，预先建立多种终端设备的类 型和多个预设高宽比的对应关系，根据该多种终端设备的类型和多个预设高宽比的对应关系，获取当前终端设备的类型对应的预设高宽比。例如，若当前终端设备是手机类型，则预设高宽比可以是4:3；若当前终端设备是个人计算机类型，则预设高宽比可以是3:4。
在一个实施例中，预先建立多种终端设备的类型和多个预设高宽比的对应关系，可以包括：对于多种类型的终端设备中的一种类型终端设备，可以通过统计采用该种类型的终端设备录制的视频的高宽比，获得统计参数，根据统计参数来确定该种类型的终端设备对应的预设高宽比。此外，预设高宽比还可以是经验值，由用户或技术人员通过大量分屏录制的实践经验得到。
在一个实施例中，终端设备获取参考视频的画面的第一高宽比；终端设备将第一高宽比和预设高宽比进行比较，得到第一比较结果。示例性地，若第一高宽比为2:1，预设高宽比为3:4，则第一比较结果为第一高宽比大于预设高宽比；若第一高宽比为3:4，预设高宽比为1:1，则第一比较结果为第一高宽比小于预设高宽比。可选地，获取参考视频的画面的第一高宽比，包括：获取参考视频的画面尺寸，包括画面宽度和画面高度，计算参考视频的画面高度和画面宽度的商，作为参考视频的画面的第一高宽比。
步骤204，根据录制视频的画面尺寸和第一比较结果，调整参考视频的画面尺寸。
其中，参考视频和录制视频为显示屏幕上分屏显示的两个视图；参考视频和录制视频可以分别左右显示，还可以分别上下显示。在本公开的实施例中，以参考视频和录制视频左右显示为例，进行详细说明。例如，参考视频位于当前显示屏幕左侧显示，录制视频位于当前显示屏幕右侧显示；或者参考视频位于当前显示屏幕右侧显示，录制视频位于当前显示屏幕左侧显示。可以理解的是，参考视频和录制视频上下显示的情形，和参考视频和录制视频左右显示的情形是相对应的，本公开的实施例中不再赘述。参考视频可以是一个，还可以是多个；当参考视频为多个时，仍可以采用参考视频为一个时的技术方案分别调整多个参考视频的画面尺寸，本公开的实施例中不再赘述。
如图3所示，并结合图1，终端设备10在分屏录制时，其显示屏幕14的显示界面可以包括：录制视频的画面、参考视频的画面。终端设备10可以将参考 视频的画面的第一高宽比和预设高宽比进行比较，得到第一比较结果，根据录制视频的画面尺寸和第一比较结果，调整参考视频的画面尺寸，终端设备在接收录制指令后，通过视频录制装置15拍摄录制视频，并将拍摄的录制视频显示在显示屏幕14上，如图3中的录制视频的画面所示。终端设备10在显示屏幕上分屏显示录制视频的同时，在显示屏幕上分屏显示调整后的参考视频，如图3中的参考视频的画面所示。终端设备10在录制完成之后或者录制过程中，可以将录制视频和调整后的参考视频进行合成处理，得到合成后的视频；终端设备10可以将合成后的视频保存在存储器12中，还可以通过通信网络将第二视频数据进行共享，例如上传至多类视频分享网站的服务器或者发送给其它终端设备。
在本实施例中，终端设备可以在对录制视频进行录制前调整参考视频的画面尺寸，也可以在录制视频进行录制的过程中调整参考视频的画面尺寸。
在一个实施例中，终端设备根据录制视频的画面尺寸和第一比较结果，调整参考视频的画面尺寸；其中，录制视频的画面尺寸为用户预先设置的画面尺寸或者该终端设备录制视频的默认画面尺寸，还可以是其它。
在一实施例中，因为用户采用参考视频作为录制视频的背景、参照或映衬，对录制视频的画面完整性等要求更高，因此通过调整参考视频的画面尺寸来提高整个视频画面的协调性和观赏效果。
在一个实施例中，当第一比较结果为第一高宽比小于预设高宽比时，即相对人眼舒适参数最优的高宽比，参考视频的画面较为扁平，为了人眼观看更为舒适，此时根据录制视频的画面尺寸和第一比较结果对参考视频的画面进行调整，使得参考视频的画面完整的呈现在当前显示屏幕中除录制视频的画面以外的区域，且参考视频的画面与录制视频的画面在视觉上协调，提高画面显示质量和用户观看舒适度。
在一个实施例中，当第一比较结果为第一高宽比大于等于预设高宽比时，即相对人眼舒适参数最优的高宽比，参考视频的画面较为瘦长，为了人眼观看更为舒适，此时根据录制视频的画面尺寸和第一比较结果对参考视频的画面进行调整，使得参考视频的画面尽可能撑满当前显示屏幕中除录制视频的画面以外的区域，且参考视频的画面与录制视频的画面在视觉上协调，提高画面显示质量和用户观看舒适度。
上述视频画面调整方法中，将参考视频的画面的第一高宽比和预设高宽比进行比较，得到第一比较结果，根据录制视频的画面尺寸和第一比较结果，调整参考视频的画面尺寸，且由于该预设高宽比对应的人眼舒适参数最优，因此，根据预设高宽比调整后的合成视频中，在显示屏幕上分屏显示的录制视频的画面和参考视频的画面在视觉上协调，提高了画面显示质量和用户观看舒适度。
在一个实施例中，如图4所示，提供了一种视频画面调整方法，可以包括以下步骤：
步骤402，将参考视频的画面的第一高宽比和预设高宽比进行比较，得到第一比较结果。
其中，预设高宽比对应的人眼舒适参数满足预设条件。步骤402的解释说明参照上述步骤202，这里不再赘述。
步骤404，根据录制视频的画面尺寸和第一比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频。
其中，缩放后的参考视频的画面尺寸与录制视频的画面尺寸相适配。其中，等比缩放处理是指对参考视频的画面进行整体缩放，画面高度的缩放比例和画面高度的缩放比例相同，避免了参考视频的画面因为变形扭曲，导致显示质量降低的问题。
在一个实施例中，缩放后的参考视频的画面尺寸与录制视频的画面尺寸相适配是指缩放后的参考视频的画面尺寸与录制视频的画面尺寸相同，或者缩放后的参考视频的画面尺寸与录制视频的画面尺寸近似，或者缩放后的参考视频的画面尺寸与录制视频的画面尺寸在一个维度上相同或近似，其中，一个维度可以是画面宽度，也可以是画面高度。
示例性地，缩放后的参考视频的画面尺寸与录制视频的画面尺寸近似，可以是(1)参考视频的画面尺寸中的画面宽度与录制视频的画面尺寸中的画面宽度相等，且参考视频的画面尺寸中的画面高度与录制视频的画面尺寸中的画面高度的差值小于预设高度阈值；或者可以是(2)参考视频的画面尺寸中的画面高度与录制视频的画面尺寸中的画面高度相等，且参考视频的画面尺寸中的画面宽度与录制视频的画面尺寸中的画面宽度的差值小于预设宽度阈值；还可以是(3)参考视频的画面尺寸中的画面高度与录制视频的画面尺寸中的画面高度 的差值小于预设高度阈值，且参考视频的画面尺寸中的画面宽度与录制视频的画面尺寸中的画面宽度的差值小于预设宽度阈值。预设宽度阈值可以是相对录制视频的画面尺寸中的画面宽度的百分比，例如1％，2％或5％等。
在一实施例中，缩放后的参考视频的画面尺寸与录制视频的画面尺寸相适配，可以为参考视频和录制视频在显示屏幕上分屏显示的两个视图的画面尺寸相同，并且该两个视图紧密贴合，即两个视图的结合部位不存在预留区域；示例性地，该预留区域可以为黑边。
在一个实施例中，根据录制视频的画面尺寸和第一比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，可以包括：若第一比较结果为第一高宽比小于预设高宽比，终端设备则根据录制视频的画面尺寸中的画面宽度，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频。
在一实施例中，缩放后的参考视频与录制视频在显示屏幕上所占的屏幕宽度相等。在一个实施例中，根据录制视频的画面尺寸中的画面宽度，对参考视频的画面尺寸进行等比缩放处理，可以包括：计算参考视频的画面尺寸中的画面宽度和录制视频的画面尺寸中的画面宽度的宽度比值，根据宽度比值，对参考视频的画面尺寸进行等比缩放处理。
示例性地，参照图5a，示出了当第一高宽比为5:4，预设高宽比为4:3，录制视频的画面的第二高宽比为16:9时参考视频与录制视频在显示屏幕上显示的示意图，此时第一高宽比小于预设高宽比；参照图5b，示出了根据录制视频的画面尺寸中的画面宽度，对参考视频的画面尺寸进行等比缩放处理后的参考视频的示意图，缩放后的参考视频与录制视频在显示屏幕上所占的屏幕宽度相等，且缩放后的参考视频的画面的上部和下部包括黑边；参照图5c，示出了缩放后的参考视频与录制视频在显示屏幕上显示的示意图。
示例性地，参照图6a，示出了当第一高宽比为1:1，预设高宽比为4:3，录制视频的画面的第二高宽比为8:7时参考视频与录制视频在显示屏幕上显示的示意图，此时第一高宽比小于预设高宽比；参照图6b，示出了根据录制视频的画面尺寸中的画面宽度，对参考视频的画面尺寸进行等比缩放处理后的参考视频的示意图，缩放后的参考视频与录制视频在显示屏幕上所占的屏幕宽度相等， 且缩放后的参考视频的画面的上部和下部包括黑边；参照图6c，示出了缩放后的参考视频与录制视频在显示屏幕上显示的示意图。
可选地，在本实施例中，缩放后的参考视频的画面的上部和/或下部包括预留区域。终端设备可以根据用户指令或预设指令调整参考视频相对于录制视频的相对显示位置，因此当该相对显示位置偏上时，缩放后的参考视频的画面的上部可以包括预留区域，下部不包括预留区域；当该相对显示位置偏下时，缩放后的参考视频的画面的下部可以包括预留区域，上部不包括预留区域；当该相对显示位置位于中间时，缩放后的参考视频的画面的上部可以包括预留区域，下部也可以包括预留区域。在一个实施例中，在将参考视频的画面的第一高宽比和预设高宽比进行比较，得到第一比较结果之后，该视频画面调整方法还可以包括：终端设备将录制视频的画面的第二高宽比与第一高宽比进行比较，得到第二比较结果。可选地，步骤“根据录制视频的画面尺寸和第一比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频”，可以包括：根据录制视频的画面尺寸、第一比较结果和第二比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频。
可选地，终端设备获取录制视频的画面尺寸的第二高宽比，将第二高宽比和预设高宽比进行比较，得到第二比较结果。示例性地，若第二高宽比为1:1，预设高宽比为3:4，则第二比较结果为第二高宽比大于预设高宽比；若第二高宽比为5:4，预设高宽比为4:3，则第二比较结果为第二高宽比小于预设高宽比。可选地，获取录制视频的画面的第二高宽比，包括：获取录制视频的画面尺寸，包括画面宽度和画面高度，计算录制视频的画面高度和画面宽度的商，作为录制视频的画面的第二高宽比。
在一实施例中，根据录制视频的画面尺寸、第一比较结果和第二比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，可以包括：若第一比较结果为第一高宽比大于或等于预设高宽比，且第二比较结果为第一高宽比大于第二高宽比，则根据录制视频的画面尺寸中的宽度，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，并根据录制视频的画面尺寸中的高度和预设的裁剪规则对缩放的参考视频进行裁剪；缩放后的参考视频与录制视频在显示屏幕上所占的屏幕宽度相等。其中，根据录制视频的画面尺寸中的高度和预设的裁剪规则对缩放的参考视频进行裁剪，可以包括：根据 录制视频的画面尺寸中的高度，裁剪掉缩放后的参考视频的画面中超出高度的部分。可以理解的是，对超出高度的部分，可以从参考视频的画面中高度方向的两端进行裁剪，也可以仅裁剪一端。
示例性地，参照图7a，示出了当第一高宽比为2:1，预设高宽比为4:3，录制视频的画面的第二高宽比为16:9时参考视频与录制视频在显示屏幕上显示的示意图，此时第一高宽比大于预设高宽比，且，第一高宽比大于第二高宽比；参照图7b，示出了根据录制视频的画面尺寸中的画面宽度对参考视频的画面尺寸进行等比缩放处理，和根据录制视频的画面尺寸中的画面高度对缩放后的参考视频进行剪裁处理的示意图；参照图7c，示出了缩放和剪裁处理后的参考视频与录制视频在显示屏幕上显示的示意图，二者在显示屏幕上显示时所占屏幕尺寸相同。
示例性地，参照图8a，示出了当第一高宽比为4:3，预设高宽比为4:3，录制视频的画面的第二高宽比为8:7时参考视频与录制视频在显示屏幕上显示的示意图，此时第一高宽比等于预设高宽比，且，第一高宽比大于第二高宽比；参照图8b，示出了根据录制视频的画面尺寸中的画面宽度对参考视频的画面尺寸进行等比缩放处理，和根据录制视频的画面尺寸中的画面高度对缩放后的参考视频进行剪裁处理的示意图；参照图8c，示出了缩放和剪裁处理后的参考视频与录制视频在显示屏幕上显示的示意图，二者在显示屏幕上显示时所占屏幕尺寸相同。
在一实施例中，根据录制视频的画面尺寸、第一比较结果和第二比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，可以包括：若第一比较结果为第一高宽比大于或等于预设高宽比，且第二比较结果为第一高宽比小于第二高宽比，则根据录制视频的画面尺寸中的高度，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，并根据录制视频的画面尺寸中的宽度和预设的裁剪规则对缩放的参考视频进行裁剪；缩放后的参考视频与录制视频在显示屏幕上所占的屏幕高度相等。其中，根据录制视频的画面尺寸中的宽度和预设的裁剪规则对缩放的参考视频进行裁剪，可以包括：根据录制视频的画面尺寸中的宽度，裁剪掉缩放后的参考视频的画面中超出宽度的部分。可以理解的是，对超出宽度的部分，可以从参考视频的画面中宽度方向的两端进行裁剪，也可以仅裁剪一端。
在该实施例中，根据录制视频的画面尺寸中的高度，对参考视频的画面尺寸进行等比缩放处理，可以包括：计算参考视频的画面尺寸中的画面高度和录制视频的画面尺寸中的画面高度的高度比值，根据高度比值，对参考视频的画面尺寸进行等比缩放处理。
示例性地，参照图9a，示出了当第一高宽比为4:3，预设高宽比为4:3，录制视频的画面的第二高宽比为16:9时参考视频与录制视频在显示屏幕上显示的示意图，此时第一高宽比等于预设高宽比，且，第一高宽比小于第二高宽比；参照图9b，示出了根据录制视频的画面尺寸中的画面高度对参考视频的画面尺寸进行等比缩放处理，和根据录制视频的画面尺寸中的画面宽度对缩放后的参考视频进行剪裁处理的示意图；参照图9c，示出了缩放和剪裁处理后的参考视频与录制视频在显示屏幕上显示的示意图，二者在显示屏幕上显示时所占屏幕尺寸相同。
在一个实施例中，根据录制视频的画面尺寸、第一比较结果和第二比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，可以包括：若第一比较结果为第一高宽比大于或等于预设高宽比，且第二比较结果为第一高宽比等于第二高宽比，则根据录制视频的画面尺寸中的宽度或高度，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频；缩放后的参考视频与录制视频在显示屏幕上所占的屏幕尺寸相等。
在一实施例中，预设的裁剪规则包括均匀裁剪规则、对齐裁剪规则、识别人物裁剪规则或根据用户指令生成的裁剪规则。例如，可以通过录制视频的画面尺寸和/或预置图像识别技术，识别缩放后的参考视频的画面的目标区域，然后根据裁剪规则，对目标区域进行裁剪。均匀裁剪规则可以是通过获取目标区域的位置坐标，对该目标区域的上、下、左、右四个位置的区域进行等比例裁剪；左右对齐裁剪可以是通过将目标区域采用左对齐或者右对齐的方式，裁剪掉多余区域；识别人物裁剪可以是通过识别目标人物的关键点坐标，对目标人物的关键点以外的其他区域进行裁剪；根据用户指令生成的裁剪规则，可以是实时根据用户指令选择与该指令相应地裁剪规则进行裁剪，例如当用户指令为第一指令时，可以选择均匀裁剪规则。
上述视频画面调整方法中，将参考视频的画面的第一高宽比和预设高宽比 进行比较，得到第一比较结果，根据录制视频的画面尺寸和第一比较结果，对参考视频的画面尺寸进行等比缩放处理，得到缩放后的参考视频，使得缩放后的参考视频与录制视频的画面尺寸相适配，且由于该预设高宽比对应的人眼舒适参数最优，因此在显示屏幕上分屏显示的录制视频的画面和参考视频的画面在视觉上协调，提高了画面显示质量和用户观看舒适度，同时避免了在调整过程中参考视频的画面因变形扭曲，导致显示质量降低的问题。
在一个实施例中，提供的一种视频画面调整方法，还可以包括：在录制录制视频的过程中，将调整后的参考视频和录制视频合成为目标视频。也就是说，在录制该录制视频的过程中，将调整后的参考视频的视频帧和该录制视频中已录制的视频帧进行合成，生成目标视频的视频帧。可以理解的是，进行合成的一组参考视频的视频帧和录制视频的视频帧在当前显示屏幕上播放时具有相同的时间戳。在本实施例中，因为采用在录制过程中进行录制视频和参考视频的合成，相比于录制完成后再开始合成视频，更加高效。
应该理解的是，虽然图2和图4的流程图中的多个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2和图4中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
