204:获取单指操作的角度,根据预设的单指操作角度与视频画面转动关系, 对视频画面进行转动, 然后执行 210。
获取单指操作的角度的示例方法如下: 预先设置一个参考射线。 可以根据 实际应用, 设置参考射线, 如可以设置与水平方向平行且方向为从左到右的直 线为参考射线; 可以从触摸屏上选取两个点, 设置从一个点到另一个点的连线 为参考射线。 总之, 可以根据实际应用灵活设置, 对此不做限定。 假设单指触 碰触摸屏时的点 P1坐标为 (xl , yl ), 单指离开触摸屏时的点 P2坐标为 (x2, y2 ), 由点 PI指向点 P2确定出另一个射线, 将参考射线和点 P1指向点 P2确定 出的射线之间的夹角作为单指操作的角度 A1。
具体地, 本公开实施例中预设的单指操作角度与视频画面转动关系包括: 165° <A1<195° 则表示单指向左滑动, 视频画面左右翻转; -15° <Α1<15。 , 则表示单指向右滑动,视频画面左右翻转; 75。 <A1<105° 则表示单指向上滑动, 视频画面上下翻转; 255。 <A1<285° 则表示单指向下滑动,视频画面上下翻转; 30° <A1<60。 则表示单指向上然后向右滑动, 视频画面顺时针旋转 90度; 120。 <A1<150° 则表示单指向上然后向左滑动, 视频画面逆时针旋转 90度; 210。 <A1<240° 则表示单指向下然后向左滑动, 视频画面顺时针旋转 90度; 300。 <A1<330° 则表示单指向下然后向右滑动, 视频画面逆时针旋转 90度。
205: 判断单指操作属于现有哪种类型的操作, 按照相应的类型对视频画面 进行处理, 然后执行 210。
206: 判断是双指操作还是多于双指的操作, 如果是双指操作, 则执行 207; 如果是多于双指的操作, 则结束。
207: 判断双指操作是否属于对视频画面进行转动的双指操作, 如果属于对
视频画面进行转动的双指操作, 则执行 208; 否则, 执行 209。
具体地, 判断双指操作是否属于对视频画面进行转动的双指操作包括: 判断双指是否同时向上或向下或向左或向右滑动, 或者
双指中是否有一个手指保持位置不变, 另一个手指进行移动;
如果是上述任一种情况, 则确定双指操作属于对视频画面进行转动的双指 操作。
208:获取双指操作的角度,根据预设的双指操作角度与视频画面转动关系, 对视频画面进行转动, 然后执行 210。
具体地, 如果双指操作是双指同时向上, 则设对应的角度为 90° ; 如果双 指操作是双指同时向下, 则设对应的角度为 270° ; 如果双指操作是双指同时向 右, 则设对应的角度为 0° ; 如果双指操作是双指同时向左, 则设对应的角度为 180。 。
如果双指操作是双指中有一个手指保持位置不变, 另一个手指进行移动, 则设保持位置不变的手指在触摸屏的坐标为 PI ( xl , yl ), 另一个手指在触碰触 摸屏时的坐标为 P2 ( x2, y2 ), 另一个手指在离开触摸屏时的坐标为 P3(x3, y3), 将射线 Pl-P2、 射线 P1-P3之间的夹角作为该情况下双指操作的角度 A2。 计算 该情况下双指操作的角度 A2为:
Λ - xl)2 + (y2 - yl)2 + (x3 - xl)2 + (y3 - yl)2 - [(x3 - x2f + (y3 - ylf ]
AZ= arccos , =—— , =
2 * - x\)2 + {yl - yl)2 ^(x3 - xl)2 + (y3 - yl)2
具体地, 本实施例中预设的双指操作角度与视频画面转动关系包括: 如果双指操作是双指同时向上, 对应的角度为 90° 时,视频画面上下翻转; 如果双指操作是双指同时向下, 对应的角度为 270° 时, 视频画面上下翻转; 如 果双指操作是双指同时向右, 对应的角度为 0° 时, 视频画面左右翻转; 如果双 指操作是双指同时向左, 对应的角度为 180° 时, 视频画面左右翻转。 当然, 这 仅仅是一种示例而已, 本领域技术人员可以根据需要灵活设置双指操作角度与 视频画面转动之间的对应关系, 例如, 上文所述的单指操作角度与视频画面转 动之间的对应关系可以应用于此。
另一方面, 如果双指操作是双指中有一个手指保持位置不变, 另一个手指 进行移动, 计算得到角度 A2时, 则同该另一个手指移动的顺时针和逆时针方向 一致, 视频画面旋转 A2度。
209: 判断双指操作属于现有哪种类型的操作, 按照相应的类型对视频画面
进行处理, 然后执行 210。
210: 显示处理后的视频画面, 然后结束。
