实施例二
本发明实施例提供了一种即时视频的显示方法，参见图2所示，方法包括：
201、获取用户在至少一帧视频画面输入的手势轨迹。
具体的，获取用户在至少一帧视频画面输入的手势轨迹的方向，手势轨迹的方向包括左右方向、上下方向以及对角方向。
在即时视频过程中，将电子设备在垂直竖屏时的位置预设为初始位置，在电子设备屏幕中手势轨迹所在的位置设置极坐标，该极坐标以手势轨迹的几何中心为原点，该极坐标参照图3中a所示。
其中，手指在屏幕中的轨迹满足第一条件，则确定为左右方向，第一条件为手势轨迹角度范围满足小于等于第一角度大于第二角度，并小于等于第三角度大于第四角度，在实际应用中，第一角度可以是-3π/8第二角度可以是-5π/8，第三角度可以是-11π/8第四角度可以是-13π/8。具体的，以实际应用中的角度为例进行说明，第一条件在极坐标中所指的区域参照图3中b所示，其中，虚线表示第一条件的范围不包含虚线所在的角度；
手指在屏幕中的轨迹满足第二条件，则确定为上下方向，第二条件为手势轨迹角度满足大于第五角度小于等于第六角度，并小于等于第七角度大于第八角度，在实际应用中，第五角度可以是-π/8第六角度可以是-15π/8，第七可以是-7π/8第八角度可以是-9π/8。具体的，以实际应用中的角度为例进行说明，第二条件在极坐标中所指的区域参照图3中c所示，其中，虚线表示第二条件 的范围不包含虚线所在的角度；

通过在即时视频过程中获取用户输入的手势轨迹，因为手势轨迹可以是在视频画面的任何位置，相比于其他点击选择等输入方法，灵活度高，方便用户操作，进一步提高了用户体验；另外，根据手势轨迹的位置而建立极坐标系，避免了只能在一个位置建立极坐标系，导致某些位置的手势轨迹不能识别的情况，从而可以根据手势轨迹满足在极坐标系中的位置而识别不同的手势轨迹，进一步满足了用户需求，提高了用户体验；同时，在即时视频中获取用户输入的手势轨迹，使得用户可以通过输入手势轨迹的方式进行即时视频的交互，增加了即时视频过程中的互动形式，进一步满足了用户需求，提高了用户体验。
202、根据手势轨迹，获取用户输入的第一显示参数。
其中，第一显示参数用于指示即时视频画面的显示比例。
具体的，根据手势轨迹，获取用户输入的第一显示参数的过程可以为：
获取用户手指在显示屏上触发起始点后，在至少一帧视频画面之后检测用户手指在屏幕中的位置与起始点之间的位移，并确定该位移所对应的显示比例为用户根据手势轨迹输入的第一显示参数。
根据位移与显示比例之间的对应关系，获取与该位移对应的显示比例，本发明实施例对具体的对应关系不加以限定。
除了通过上述方式实现根据手势轨迹，获取用户输入的第一显示参数的外， 还可以通过其他方式实现该过程，本发明实施例对具体的方式不加以限定。
通过检测用户手指在屏幕中的位置与起始点之间的位移，根据用户的手势轨迹的位移确定该位移对应的显示参数为用户输入的第一显示参数，使得获取第一显示参数的方式更加简洁方便，易于操作，从而满足了用户需求，提高了用户体验。
203、根据手势轨迹，获取位置参数。
其中，位置参数至少包括位置的坐标。
位置参数用于指示所要调整的即时视频画面区域。
具体的，获取该位置的坐标的过程可以为：获取手势轨迹的几何中心，该几何中心的坐标为该位置的坐标。
除此之外，还可以包括其他的位置参数，本发明实施例对具体的位置参数不加以限定。
示例性的，假设图4中虚线所示的轨迹为用户输入的手势轨迹，在图4中该手势轨迹的几何中心为该虚线的中点，该中点的坐标为该位置的坐标。
通过获取手势轨迹在即时视频画面中的位置，获取该位置的坐标，从而可以识别手势轨迹在即时视频画面中的位置，实现了对即时视频画面中任意手势轨迹位置的确定，进一步满足了用户需求，提高了用户体验。
可选的，方法还包括：
确定所要调整的即时视频画面区域。
具体的，根据位置坐标和手势轨迹确定所要调整的即时视频画面区域。
通过选择预先存储的形状，本发明实施例对具体的形状不加以限定，确定所要调整的即时视频画面区域，该预先存储的形状包括圆形、椭圆形、长方形、正方形以及三角形等，该过程可以为：
选择预先存储的形状；
以该位置坐标为中心，根据手指滑动的位置，确定该形状所在的位置，该形状的大小可以根据手指的滑动进行控制；
该形状所在的区域即为所要调整的即时视频画面区域。
为了使得本领域的技术人员进一步理解本发明实施例所述的方法，下面将举例对本发明实施例所述的方法进行说明，假设选择的预先存储的形状是圆形，则以起始手势轨迹的几何中心为该圆开始的圆心，以开始手势轨迹的长度为直径，确定该圆的位置，随着手指的滑动，若手势轨迹的几何中心未发生变化，则根据手势轨迹的长度放大或缩小圆的区域，若手势轨迹的几何中心发生变化，则重新以该手势轨迹的几何中心为圆心，该手势轨迹的长度为直径，确定圆的位置。
若选择的预先存储的形状是椭圆形，则以起始手势轨迹的几何中心为该椭圆开始的焦点，以开始手势轨迹的长度为椭圆的长轴，短轴为系统默认的短轴，确定该椭圆的位置，随着手指的滑动，若手势轨迹的几何中心未发生变化，则根据手势轨迹的长度放大或缩小椭圆的区域，若手势轨迹的几何中心发生变化，则重新以该手势轨迹的几何中心为焦点，该手势轨迹的长度为长轴，确定椭圆的位置。
以此类推，若通过选定正方形或长方形等其他预先存储的形状，则确定所要调整的区域的方法同上述方法类似，不再一一进行列举。
通过根据手势轨迹的变化，确定形状的位置，使得确定的形状的位置可以不断的跟随手势轨迹位置的变化而变化，从而提高了用户体验，满足了用户需求。
除了上述方式外，还可以通过选择形状图标至所要调整的即时视频画面中，对该形状图标进行拉伸或压缩改变大小，以确定所要调整的即时视频画面区域，选择的方式可以是点击，也可以是拖动，本发明实施例对具体的方式不加以限定；还可以在即时视频画面中拖动该形状以改变该形状在即时视频画面的位置以确定所要调整的即时视频画面区域。
需要说明的是，若用户预先未选择所需的形状，则以默认的形状确定的区域为所要调整的即时视频画面区域，该默认的形状可以为圆形、也可以为椭圆 形、还可以为其他的形状，本发明实施例对具体的默认形状不加以限定。
示例性的，若选择预先存储的形状为椭圆形，界面图可以参照图5中a所示，假设图5的b中的虚线所示的轨迹为用户输入的手势轨迹，则以该手势轨迹的几何中心的坐标为位置的坐标，确定的所要调整的即时视频画面区域可以参照图5中c所示，随着手势轨迹按虚线箭头所示的两侧方向进行形状放大的调整，若手势轨迹的几何中心未发生变化，则调整后的即时视频画面区域可以参照图5中d所示，若手势轨迹的几何中心发生变化，则调整后的即时视频画面区域可以参照图5中e所示。
通过选择预先存储的形状，根据位置坐标和手势轨迹确定所要调整的即时视频画面区域，使得获取的所要调整的即时视频画面的区域更加明确，实现了用户根据自身的需求对选定区域的显示比例进行调整，从而进一步满足了用户需求，提高了用户体验；另一方面，可以预先存储多种不同的形状，从而可以满足用户选择与自身所要调整的区域相符合的形状，以方便对所要调整的即时视频画面区域的确定，增加了互动性和即时视频画面的显示形式，进一步提高了用户体验，满足了用户需求。
可选的，还可以通过用户即时输入的闭合曲线确定所要调整的即时视频画面区域。
具体的，用户可以直接通过手指的滑动输入闭合的滑动轨迹曲线，确定所要调整的即时视频画面区域，还可以通过笔触特效，输入闭合的滑动轨迹曲线，确定所要调整的即时视频画面区域，还可以是其他方式，本发明实施例对具体的方式不加以限定。
示例性的，参照图6中a所示的图标为笔触图标，用户点击该图标，参照图6中b所示的闭合曲线可以是用户在即时视频上通过笔触输入的闭合曲线，该闭合曲线的区域即为所要调整的即时视频画面的区域。
通过用户手指输入或笔触特效输入的闭合曲线确定所要调整的即时视频画面区域，使得确定所要调整的即时视频画面区域的方式更加灵活，增加了即时 视频的画面的显示形成，进一步满足了用户需求，提高了用户体验。
可选的，方法还包括
获取所要调整的即时视频画面区域的特征参数，通过该特征参数在下一帧即时视频画面中确定该区域，本发明实施例对具体的方式不加以限定。
通过获取所要调整的即时视频画面区域的特征参数，在下一帧画面中确定该即时视频画面区域，从而实现了在即时视频过程中，由于人脸位置的移动，使得确定的区域发生变化的情况，实现了对确定的即时视频画面的跟踪定位，进一步满足了用户需求，提高了用户体验。
需要说明的是，对步骤202和步骤203在实际应用中的先后顺序不加以限定，也可以是先执行203步骤再执行202步骤，还可以是同时执行步骤202和步骤203。
需要说明的是，步骤201至步骤203是获取用户触发的第一显示参数和触发第一显示参数的位置参数的过程，除了上述方式外，还可以包括其他方式，本发明实施例对具体的方式不加以限定。
通过用户输入的第一显示参数和位置参数，使得用户可以根据自身的需求在即时视频画面中选择需要调整的位置，实现了用户对即时视频画面不同位置的显示比例的调整，增加了即时视频画面的显示方式，从而进一步满足了用户需求，提高了用户体验；另一方面，通过在即时视频过程中调整即时视频画面，增加了用户在即时视频过程中的互动形式，进一步满足了用户需求，提高了用户体验。
204、根据第一显示参数，对即时视频画面区域的像素间距进行调整，生成调整后的即时视频画面。
具体的，根据第一显示参数，对即时视频画面区域的像素间距进行调整包括：像素间距拉伸和像素间距压缩，拉伸时的方向包括左右方向、上下方向以及对角方向，压缩时的方向包括左右方向、上下方向以及对角方向，其中，若手势轨迹为用户手指由中间向两侧滑动生成，则该手势轨迹的方向为拉伸时的 方向，若手势轨迹为用户手指由两侧向中间滑动生成，则该手势轨迹的方向为压缩时的方向。
为了进一步说明本发明实施例所述的方法，以调整第i帧视频画面中某一区域的像素间距至第i+1帧视频画面为例进行说明：
若手势轨迹方向为左右方向，根据第一显示参数，调整第i+1帧即时视频画面所要调整区域内的左右像素间距为第五数值、上下像素间距为第六数值，调整第i+1帧即时视频画面所要调整区域外的左右像素间距为第七数值、上下像素间距为第八数值，第五数值与第七数值对应、第六数值和第八数值对应，对具体的对应关系不加以限定；
需要说明的是，第五数值对应的区域和第七数值对应的区域对应、第六数值对应的区域和第八数值对应的区域对应；
假设第i帧视频画面该区域内的左右像素间距为第一数值、上下像素间距为第二数值，第i帧视频画面该区域外的左右像素间距为第三数值、上下像素间距为第四数值；
需要说明的是，第一数值对应的区域和第三数值对应的区域对应、第二数值对应的区域和第四数值对应的区域对应；
在第五数值大于第一数值、第六数值大于第二数值，对应的，第七数值小于第三数值、第八数值小于第四数值时，增大了第i+1帧视频画面所要调整区域内的像素间距，减小了所要调整区域外的像素间距，可以实现第i+1帧视频画面该区域内的像素间距增大，该区域外的像素间距缩小；
在第五数值小于第一数值、第六数值小于第二数值，对应的，第七数值大于第三数值、第八数值大于第四数值时，减小了第i+1帧视频画面所要调整区域内的像素间距，增大了所要调整区域外的像素间距，可以实现第i+1帧视频画面该区域内的像素间距的缩小，该区域外的像素间距的增大。
若轨迹方向为上下方向时，对即时视频画面所要调整区域的像素间距进行调整的方法与轨迹方向为左右方向的调整方法相同。
若手势轨迹方向为对角方向，根据第一显示参数，调整第i+1帧即时视频画面所要调整区域内的像素间距为第十一数值，调整第i+1帧即时视频画面所要调整区域外的像素间距为第十二数值，第十一数值与第十二数值对应，对第十一数值和第十二数值具体的对应关系不加以限定；
假设第i帧视频画面该区域的像素间距为第九数值，第i帧视频画面该区域外的像素间距为第十数值；
在第十一数值大于第九数值，对应的，第十二数值小于第十数值时，增大了第i+1帧视频画面所要调整区域内的像素间距，减小了所要调整区域外的像素间距，可以实现第i+1帧视频画面该区域内的像素间距增大，该区域外的像素间距缩小；
在第十一数值小于第九数值，对应的，第十二数值大于第十数值时，减小了第i+1帧视频画面所要调整区域内的像素间距，增大了所要调整区域外的像素间距，可以实现第i+1帧视频画面该区域内的像素间距的缩小，该区域外的像素间距的增大。
示例性的，当电子设备屏幕为竖直方向时，假如所要调整的即时视频画面区域是参照图7中a所示的区域，如果对该区域进行左右方向的拉伸，则该区域内的像素间距被拉伸，拉伸方向可以参照图7中b的箭头方向所示，左右箭头表示向左右方向拉伸，上下箭头表示向上下方法拉伸，其中，左右方向的箭头长度比上下方向的箭头的长度长，表示左右方向的拉伸大于上下放下的拉伸；假如对该区域进行左右方向的压缩，压缩方向可以参照图7中c的箭头方向所示，左右箭头表示向左右方向压缩，上下箭头表示向上下方法压缩，其中，左右方向的箭头长度比上下方向的箭头的长度长，表示左右方向的压缩大于上下放下的压缩。
当电子设备屏幕处于水平位置时，左右方向的压缩调整和左右方向的拉伸调整、上下方向的压缩调整和上下方向的拉伸调整以及对角方向的压缩调整和对角方向的拉伸调整方法与电子设备屏幕处于竖直位置时的调整方法相同，此 处不再加以赘述。
通过第一显示参数的指示，不仅可以实现的对即时视频画面所要调整区域的像素间距的上下方向的拉伸和压缩，也可以实现对即时视频画面所要调整区域的像素间距的左右方向的拉伸和压缩，还可以通过对角方向，实现对即时视频画面所要调整区域的像素间距呈同心圆式的拉伸和压缩，从而通过对即时视频画面的像素间距的调整，实现了对即时视频画面的显示比例的调整，增加了即时视频的显示形式，使得用户可以根据自己的需求对即时视频画面的显示比例进行调整，从而进一步满足了用户需求，提高了用户体验。
可选的，本实施例的即时视频的显示方法还包括：
对调整后的即时视频画面进行处理。
具体的，还可以对调整后的即时视频画面进行模糊处理，模糊处理可以通过高斯模糊算法实现。
通过对调整后的即时视频画面进行模糊处理，可以增加视频画面被拉伸或压缩后的显示效果，尤其是在像素分辨率比较低的时候，对拉伸或者压缩后的即时视频进行模糊处理，能够提高视频画面质量，从而进一步提高了用户体验，满足了用户需求。
205、显示调整后的即时视频画面。
具体的，本发明实施例对具体的显示调整后的即时视频画面的方式不加以限定。
通过显示调整后的即时视频画面，增加了即时视频画面的显示形式，使得用户可以根据自己的需求对即时视频画面不同区域的显示比例进行调整，进一步满足了用户需求，提高了用户体验。
可选的，参见图8所示，本实施例的即时视频的显示方法还可以包括：
206、判断屏幕是否发生旋转，若是，则执行步骤207及207之后的步骤；若否，则继续执行步骤206。
具体的，将屏幕初始所在的位置角度预设为0°，通过第一预设公式确定屏 幕当前所处的角度，若当前的角度与初始角度相比不为0，则确定为屏幕发生了旋转。
第一预设公式可以为：
rotation＝2*arctan(Gx,Gy)-π
其中，rotation表示电子设备旋转过程中的偏离角，Gx表示重力加速度在电子设备水平方向的分量，Gy表示重力加速度在电子设备竖直方向的分量。
Gx和Gy分别可以通过电子设备自身的重力加速器进行获取，该重力加速器对电子设备各个方向的重力加速度值进行实时获取。
通过重力加速器实时获取电子设备各个方向的重力加速度值，相比其他方法节约了终端计算量，以最低的代价实现了较好的调整比例的效果，因为使用该方法不会影响终端硬件的使用，从而满足了用户需求，提高了用户体验。
207、获取屏幕旋转的角度。
具体的，根据第一预设公式的计算结果获取屏幕旋转的角度。
其中，旋转角度的取值范围为：
-π/2≤rotation＜0
-π≤rotation＜-2/π,
-3*π/2≤rotation＜-π,
-2π≤rotation＜-3*π/2
以电子设备屏幕竖直放置时为初始位置为例进行说明，即此时为0°，若向右旋转至水平位置，即-90°位置时，角度的旋转范围为：
-π/2≤rotation＜0，
若由-90°位置向右旋转至倒立竖直位置，即-180°位置时，角度的旋转范围为：
-π≤rotation＜-2/π，

rate＝Rmax+Rrange*rotation/(π/2)，-π/2≤rotation＜0；
当屏幕由-90°位置旋转至-180°位置时，则对应的第二显示参数为：
rate＝Rmax-Rrange*(π+rotation)/(π/2)，-π≤rotation＜-π/2；
当屏幕由-180°位置旋转至-270°位置时，则对应的第二显示参数为：
rate＝Rmin+Rrange*((π/2)*3+rotation)/(π/2)，-3*π/2≤rotation＜-π；
当屏幕由-270°位置旋转至-360°时，即初始位置，则对应的第二显示参数为：
rate＝Rmax-Rrange*((π/2)+rotation)/(π/2)，-2π≤rotation＜-3*π/2。
