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、完整的描述，显然，所描述的实施例仅仅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做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。
图1为本发明实施例提供的一种放大视频图像的方法的流程图。图1所示的放大 视频图像的方法，可以用于移动终端中。本发明提供的放大视频图像的方法可以在视频窗口中观看放大后的目标显示区域内的视频图像，以使用户可以在视频窗口中看清目标显示区域内的视频图像，从而满足了用户的观影需求。该方法包括以下步骤。
步骤S11、在显示屏幕的目标显示区域接收到按压操作时，检测按压操作对应的压力值。
其中，本发明提供的方法可以应用于具有显示屏幕的移动终端内，移动终端可以为智能手机或平板电脑等设备。
显示屏幕的目标显示区域指的是用户利用手指或触摸笔按压的区域。例如，用户利用手指按压了显示屏幕的中心区域，那么显示屏幕的中心区域即为目标显示区域。又如，用户利用触摸笔按压了显示屏幕的右上区域，那么显示屏幕的右上区域即为目标显示区域。
移动终端的显示屏幕上可以设置感应压力的传感器，在显示屏幕显示视频图像时，用户可以利用手指或触摸笔按压显示屏幕的任意显示区域。在显示屏幕的目标显示区域接收到用户输入的按压操作时，显示屏幕上的传感器会检测该按压操作的压力值。
例如，假设移动终端为配备触摸屏幕的智能手机，而且该触摸屏上设置有压力传感器，该智能手机当前正在显示视频图像。在用户利用手指按压触摸屏幕上的目标显示区域，智能手机的触摸屏幕便会检测用户利用手指按压的压力值。假设用户利用手指使用2牛的力按压触摸屏幕的目标显示区域时，那么智能手机的触摸屏幕便会检测出按压操作的压力值为2牛。
步骤S12、在按压操作对应的压力值大于阈值时，在显示屏幕的预设位置上生成视频窗口。
其中，阈值指的是预先设置好的压力值，例如，可以预先将阈值设置为3牛。阈值可以由用户根据自身习惯来设置。当然，阈值也可以在出厂时进行统一设置，以使用户不能随意更改。
显示屏幕的预设位置为预先设置好的位置，例如，可以将预设位置设置在显示屏幕的右上角；又如，可以将预设位置设置在显示屏幕的左上角。
在移动终端判断出按压操作对应的压力值大于阈值时，说明用户想要仔细的观看目标显示区域内的视频图像，那么移动终端便会在显示屏幕的预设位置上生成视频窗口，以便于移动终端将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中，以使得用户能够在视频窗口中观看到放大后的目标显示区域内的视频图像。
视频窗口的边框可以根据实际要显示的视频图像的大小而发生变化，所以视频窗口的大小并不固定。
步骤S13、将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
其中，预设倍数指的是预先设置好的倍数。例如，可以预先将预设倍数设置为2倍。
移动终端在显示屏幕的预设位置上生成视频窗口以后，移动终端便会将目标显示区域内的视频图像放大至预设倍数，然后再将放大后的视频图像显示在视频窗口中，以便于用户能够在视频窗口中看清目标显示区域内的视频图像。
例如，预先对以下参数进行设置，其中，阈值为1牛，显示屏幕的预设位置为显示屏幕的右上角，预设倍数为2倍。假设用户正在使用移动终端的显示屏幕观看明星A的演唱会，由于显示屏幕显示出的是整个舞台的视频图像，用户无法看清处于显示屏幕的中心区域的明星A，所以用户在显示屏幕的中心区域进行按压。此时，显示屏幕的中心区域接收到用户输入的按压操作，移动终端会检测按压操作对应的压力值。移动终端检测出按压操作对应的压力值为3牛，移动终端可以判断出按压操作对应的压力值3牛大于阈值1牛，那么移动终端便会在显示屏幕的右上角生成一个视频窗口，并将显示屏幕的中心区域内的视频图像放大至2倍后显示在视频窗口中，以使得用户在视频窗口中能够看清中心区域内的视频图像。
在图1所示的实施例中，在目标显示区域接收到按压操作对应的压力值大于阈值时，说明用户想要观看目标显示区域放大后的视频图像。为此，本发明提供的方案会在显示屏幕的预设位置上生成视频窗口，以便于将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。此时，用户便可以在视频窗口中观看放大后的目标显示区域内的视频图像，以使用户可以在视频窗口中看清目标显示区域内的视频图像，从而满足了用户的观影需求。
图2为本发明实施例提供的另一种放大视频图像的方法的流程图。图2为基于图1的一个可选的实施例，在图2所示的实施例中，与图1所示的实施例相同的部分可以参见图1所示的实施例中介绍和解释。图2所示的方法包括以下步骤。
步骤S21、在显示屏幕的目标显示区域接收到按压操作时，检测按压操作对应的压力值。
步骤S22、在按压操作对应的压力值大于阈值时，在显示屏幕的预设位置上生成视频窗口。
步骤S23、将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
步骤S24、利用图像识别技术识别出目标显示区域内的人脸图像。
其中，图像识别技术可以通过识别人脸五官来确定目标显示区域内是否存在人脸图像。
例如，假设显示屏幕的目标显示区域内的视频图像为明星A的人脸图像，在移动终端将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中以后，移动终端会继续利用图像识别技术识别出目标显示区域内的明星A的人脸图像。
步骤S25、在人脸图像从目标显示区域移动至指定显示区域时，将指定显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
其中，在移动终端识别出目标显示区域内的人脸图像以后，移动终端会判断该人脸图像是否从目标显示区域移动至其他显示区域。在移动终端判断出人脸图像从目标显示区域移动至指定显示区域时，说明用户关注的人脸图像已经不再目标显示区域，而在显示屏幕的指定显示区域内，所以为了视频窗口中始终显示着用户关注的人脸图像，移动终端会将指定显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
图3为本发明实施例提供的又一种放大视频图像的方法的流程图。图3为基于图1的一个可选的实施例，在图3所示的实施例中，与图1所示的实施例相同的部分可以参见图1所示的实施例中介绍和解释。图3所示的方法包括以下步骤。
步骤S31、在显示屏幕的目标显示区域接收到按压操作时，检测按压操作对应的压力值。
步骤S32、在按压操作对应的压力值大于阈值时，在显示屏幕的预设位置上生成视频窗口。
步骤S33、将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
步骤S34、确定视频窗口的显示时长和生成视频窗口的起始时间。
其中，视频窗口的显示时长指的是视频窗口存在于显示屏幕上的时间长度。例如，假设预先将视频窗口的显示时长设置为1分钟，那么移动终端会在生成视频窗口时开始计时，在视频窗口存在于显示屏幕上的时间长度等于1分钟的时候，移动终端便会关闭该视频窗口。
在很多情况下，用户并不希望视频窗口长期停留在显示屏幕上，所以移动终端在生成视频窗口以后，便需要确定视频窗口的显示时长和生成视频窗口的起始时间。
步骤S35、在当前时间与起始时间的差值等于显示时长时，关闭视频窗口。
其中，移动终端在确定视频窗口的显示时长和生成视频窗口的起始时间以后，便开始判断当前时间与起始时间的差值是否等于显示时长。在移动终端判断出当前时间与起始时间的差值等于显示时长时，那么移动终端会关闭视频窗口。
例如，假设用户预先将视频窗口的显示时长设置为1分钟。在移动终端将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中以后，移动终端便会确定视频窗口的显示时长和生成视频窗口的起始时间，假设移动终端确定出生成视频窗口的起始时间12点10分，然后移动终端便会判断当前时间与起始时间12点10分的差值是否等于显示时长。在当前时间为12点11分的时候，移动终端判断出当前时间12点11分与起始时间12点10分的差值1分钟等于显示时长1分钟，所以移动终端便会关闭视频窗口，以满足用户的需求。
图4为本发明实施例提供的又一种放大视频图像的方法的流程图。图4为基于图1的一个可选的实施例，在图4所示的实施例中，与图1所示的实施例相同的部分可以参见图1所示的实施例中介绍和解释。图4所示的方法包括以下步骤。
步骤S41、在显示屏幕的目标显示区域接收到按压操作时，检测按压操作对应的压力值。
步骤S42、在按压操作对应的压力值大于阈值时，在显示屏幕的预设位置上生成视频窗口。
步骤S43、将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
步骤S44、确定视频窗口的显示时长。
其中，视频窗口的显示时长指的是视频窗口存在于显示屏幕上的时间长度。例如，假设预先将视频窗口的显示时长设置为2分钟，那么移动终端会在生成视频窗口时开始计时，在视频窗口存在于显示屏幕上的时间长度等于2分钟的时候，移动终端便会关闭该视频窗口。
步骤S45、在经过显示时长后确定目标显示区域所承受的目标压力值。
其中，在移动终端确定视频窗口的显示时长以后，移动终端需要等待显示时长，然后再次确定目标显示区域所承受的目标压力值，以此来判断用户是否希望继续在显示屏幕上显示视频窗口。
步骤S46、判断目标压力值是否大于阈值。在目标压力值大于阈值时，触发步骤S45。在目标压力值小于或等于阈值时，触发步骤S47。
其中，在移动终端确定出目标显示区域所承受的目标压力值以后，移动终端还需要判断目标压力值是否大于阈值。在目标压力值大于阈值时，说明用户再次按压了目标显示区域，也说明了用户希望继续观看视频窗口，所以移动终端便不会关闭视频窗口，移动终端会执行步骤S45。在目标压力值小于或等于阈值时，说明用户不想再继续观看视频窗口了，所以移动终端会关闭视频窗口。
步骤S47、关闭视频窗口。
图5为本发明实施例提供的又一种放大视频图像的方法的流程图。图5为基于图1的一个可选的实施例，在图5所示的实施例中，与图1所示的实施例相同的部分可以参见图1所示的实施例中介绍和解释。图5所示的方法包括以下步骤。
步骤S51、在显示屏幕的目标显示区域接收到按压操作时，检测按压操作对应的压力值。
步骤S52、在按压操作对应的压力值大于阈值时，在显示屏幕的预设位置上生成视频窗口。
步骤S53、将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
步骤S54、在按压操作由目标显示区域移动至指定显示区域，将指定显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
其中，在移动终端将目标显示区域内的视频图像放大至预设倍数后显示在视频窗口中以后，移动终端会判断按压操作是否由目标显示区域移动至指定显示区域。在移动终端判断出按压操作由目标显示区域移动至指定显示区域时，说明用户此时想要仔细观看指定显示区域内的视频图像，那么移动终端便会将指定显示区域内的视频图像放大至预设倍数后显示在视频窗口中。
另外，移动终端可以通过按压操作的压力值来判断按压操作是否由目标显示区域移动至指定显示区域。如果移动终端判断出目标显示区域的压力值小于阈值，但是指定显示区域的压力值大于阈值，那么便说明按压操作由目标显示区域移动至指定显示区域。
