本发明实施例一的多画面显示的控制方法可由图 2所示的控制设备来执 行, 图 5为本发明实施例一的多画面显示的控制方法的流程示意图。 如图 5所 示, 该方法具体包括以下步骤:
步骤 S101 , 接收用户操作的滑动轨迹, 根据所述用户操作的滑动轨迹进 行多画面分割线的操作;
步骤 S102, 根据操作后的多画面分割线所形成的多画面显示模式, 控制 目标展幕进行画面显示。
具体地, 视频会议系统中, 会场的屏幕可以按照单屏显示模式或多画面 显示模式显示会场图像。 在单屏显示模式下, 屏幕中不包含分割线, 在多画 面显示模式下, 多画面之间的分割是通过设置在任意两画面间的多画面分割 线来实现的。
用户对控制设备的控制区域进行操作。 控制设备的控制接口将用户操作 转化为设备可执行的操作信息, 即多画面分割线操作信息, 并根据多画面分 割线操作信息对显示区域的边界的多画面分割线进行调节, 该调节例如包括 增加、 删除、 移动和 /或旋转等, 从而实现多画面显示模式的调节。 其中, 用 户操作可以为任一种操作, 例如包括用户的触碰(单击)操作、 双击操作、 拖动操作或长时间按压操作等。
根据本实施例的多画面显示的控制方法, 由于用户可通过对控制设备进 行点击和拖动等操作, 针对多画面显示模式中的多画面分割线进行操作, 从 而获得按照调节后的多画面分割线形成的多画面显示模式, 实现了多画面显 示模式的直观、 灵活设置。 实施例二
在实施例一的基础上, 本实施例的多画面显示的控制方法中, 用户可通 过触摸控制设备实现多画面显示模式设置。 具体地, 用户可通过触摸控制设 备的控制区域的方式, 对多画面分割线(以下简称为 "分割线" )进行生成、 删除、 移动和旋转等操作。 下面分别针对上述各种多画面分割线的操作进行 详细说明。
(一)用户以触摸方式生成分割线。 图 6为生成多画面分割线的示意图。 如图 6所示, 例如用户欲在屏幕上画 一条从 A点到 B点的线, 可以先用手指在屏幕的 A点点击, 然后在用手指在控 制设备屏幕的 B点点击, 在结束操作后, 即得到 A到 B的一个直线, 如图 6中的 ( a ) 所示, 该操作作为多画面分割线生成信息保存下来; 用户也可以在 A点 点击后, 一直在屏幕上拖动, 控制设备记录下手指触摸屏幕的轨迹, 生成一 条从 A点到 B点的曲线, 如图 6中 (b )所示的实线; 在用户结束操作后, 控制 设备根据该曲线的 A点和 B的坐标,生成一条从 A点到 B点的直线,如图 6中(b ) 所示的虚线, 该直线的属性信息, 可以包括该直线的端点坐标(起始端点 A的 坐标和结束端点 B坐标), 被作为多画面分割线生成信息保存下来。 若控制设 备允许用户在绘制的过程中任意以自由态任意拖动,则需要计算最终生成的 A 点和 B点直线的倾斜率; 控制设备还可以在用户生成分割线时给予约束, 即只 允许在绘制时沿水平或者垂直方向进行延伸。
(二)用户以触摸方式移动 (平移)分割线。
图 7为移动多画面分割线的示意图。 如图 7所示,首先用触摸的方式选定 分割线 AB, 选定的方式可以用长按该分割线的方式选定, 然后用触摸的方式 将分割线 AB从位置 1 1 '拖动到 22' , 操作完毕后, 以 22'的端点坐标作为该直线 的新的属性信息, 该操作对应移动一个分割线的多画面分割线移动信息。
下面, 对选定分割线的方式进行具体说明。 图 8为选择多画面分割线的第 一示意图, 釆用点选的方式来选定分割线, 即接收所述用户对多画面分割线 的点击操作, 将所述点击操作所选中的多画面分割线确定为所述待操作的多 画面分割线。 如图 8所示, 以一个典型 3 x 3的多画面配置模式为例, 从 A点到 H点由三段分割线组成, 即 AC、 CE和 EH。 当用户需要选择某一段分割线进行 操作时, 用手指选定该段分割线两点间的任一点即可选定该段分割线进行操 作, 例如要对 AC段进行操作, 用手指选定 AC段上的 B点即可。 这适用于对除 了端点之外无其它中间分割点的线段进行选择, 并进行删除和移动等操作。 如果要进行跨段操作, 例如要对 AE段进行操作, 则需要分别选定 AC段的某一 点 (例如 B点)和 CE段的某一点 (例如 D点),选定后, AC和 CE段可看作一条完整 的分割线进行操作。 例如要对 AH段进行操作, 则需要在 AC段和 EH段进行分 别选定一点, 例如 B点和 F点, 上述是釆用选点的方式来确定待选择的分割线。
此外, 可以用框选的方式选中要操作的分割线。 图 9为选择多画面分割线 的第二示意图。 如图 9所示, 要选择 AH , 则在屏幕上先选择 LT1点, LT1点要 在该屏幕对应的显示框之外; 再滑动到多画面屏幕之外的区域 RB1点, LT1和 RB1则分别为选择框 L1的左上顶点坐标和右下顶点坐标, 可见框 L1完整包含 的分割线包括 AH , 则表示选定了 AH; 同理, 由于根据左上顶点坐标 LT2和右 下顶点坐标 RB2所构成的 L2并没有完整的包含 IP, 因此用 L2仅能选定分割线 IM以进行进一步的操作。
(三)用户以触摸方式删除分割线。
用户首先选择屏幕上用以分割多画面的分割线, 然后按照上述移动分割 线的方式, 将该分割线拖出控制区域, 即表示将该分割线不再影响多画面的 配置, 由配置多画面的其它分割线来生成对应的多画面, 该操作对应删除一 个分割线的多画面分割线删除信息。
(四)用户以触摸方式旋转分割线。
图 10为旋转多画面分割线的第一示意图。 如图 10所示, 首先用触摸的方 式选定分割线 AB, 选定的方式可以用长按该分割线的方式选定, 用两个手指 选定分割线 AB上的两点, 然后用触摸的方式将分割线 AB从 1 1 '旋转到 22' , 操 作完毕后, 以 22'的端点坐标作为该直线的新的属性信息, 该操作对应旋转一 个分割线的多画面分割线旋转信息。
用户除通过上述方式对分割线进行操作以外, 控制设备的辅助区域还可 提供各种多画面分割线操作信令对应的操作按钮, 例如包括多画面分割线生 成按钮、 多画面分割线移动按钮、 多画面分割线旋转按钮或多画面分割线删 除按钮。 在此情况下, 用户可通过点击相应操作按钮、 选择需操作的分割线 及相关位置即可完成对分割线的操作。 由于在实际应用中, 多画面分割线通 常应垂直或水平, 因此旋转角度通常为 90度或 180度, 但作为技术方案, 本发 明并不排除非 90度或者 180的旋转操作, 其实现方式类似, 在此不再赘述。
控制设备通过上述用户操作得到了对应的多画面分割线操作信息后, 根 据多画面分割线操作信息, 生成对应的多画面显示模式, 具体说明如下。
图 1 1为根据多画面分割线生成信息设置多画面显示模式的第一示意图。 如图 1 1所示, 例如欲在一个没有显示任何会场图像的屏幕上配置一个四画面 的多画面显示模式, 包括以下两个步骤:
(1)首先使用多画面分割线生成信息生成第一分割线 ΑΑ', 将目标屏幕分 为一个 1 x 2的多画面;
(2)使用另一多画面分割线生成信息生成第二分割线 ΒΒ',则目标屏幕调整 为一个 2 X 2的多画面。
图 12为根据多画面分割线生成信息设置多画面显示模式的第二示意图。 如图 12所示, 例如欲将一个目前单屏显示会场图像的屏幕配置为一个四画面 的多画面显示模式, 则当会场 S1已经显示在目标屏幕中时(如图 12的(a )所 示) , 生成第一分割线 AA'后, 会场 S1自动调整到左侧显示区域内 (如图 12 的 (b )所示) , 之后再生成第二分割线 BB' (如图 12的 (c )所示) , 屏幕 调整为一个四画面显示模式, 并将会场 S1自动调整到左上显示区域显示 (如 图 12的 (d )所示) 。
图 13为根据多画面分割线删除信息设置多画面显示模式的第一示意图。 如图 13所示, 例如欲将显示有一个会场 S1的四画面屏幕配置为一个 1 χ 2的多 画面显示模式, 初始状态下多画面显示模式如图 13中的 (a ) 所示, 会场 S1 的画面在目标屏幕的左上角显示; 删除分割线 ΑΑ', 生成的多画面显示模式如 图 13中的(b )所示, 会场 S1的画面自动调节到目标屏幕的上半部显示区域显 示。 至此, 获得了 1 X 2的多画面显示模式。
(2)使用另一多画面分割线生成信息生成第二分割线 ΒΒ',则目标屏幕调整 为一个 2 X 2的多画面。
图 14为根据多画面分割线移动信息设置多画面显示模式的第一示意图。 控制设备根据多画面分割线移动信息可实现多画面显示模式下, 各子画面的 大小调节。 如图 14所示, 初始状态下, 多画面显示模式如图 14中的(a )所示, 会场 S1显示在目标屏幕上的左上角区域; 控制设备根据多画面分割线移动信 息, 将分割线 AA'移动至 CC', 此时的多画面显示模式如图 14中的 (b )所示; 之后, 控制设备自动将会场 S1的画面调节至子画面的中间位置进行显示, 该 子画面的两侧位置为空闲区域, 如图 14中的(c )所示。 控制设备还可根据调 节后的子画面尺寸对子画面内的会场 S1的图像进行裁剪和 /或缩放, 以使会场 S1的图像将所在子画面填满。
图 15为根据多画面分割线移动信息设置多画面显示模式的第二示意图。 用户还可通过同时移动两条相互交叉的分割线进行多画面显示模式设置。 如 图 15中 (a ) 所示, 会场 S1显示在目标屏幕上的左上角区域, AA'和 BB'的交 叉点为 O点; 如图 15中 (b )所示, 用户选择分割线 AA'和 BB'的交叉位置 0, 并拖动交叉点位置到 0, , 则分割线 AA'调节至 CC', 分割线 BB'调节至 DD'; 控制设备将多画面调整为一个如图 15中(c )所示的四画面, 并将会场 S1自动 调整至新的区域大小进行显示。
图 16为根据多画面分割线旋转信息设置多画面显示模式的第一示意图。 以将左右方式显示的多画面显示模式调整为上下方式显示的多画面显示模式 为例进行说明。 初始状态下, 如图 16中 (a )所示, 会场 S1的图像显示在屏幕 的左侧; 如图 16中 (b )所示, 用户选定分割线 ΑΑ'; 如图 16中 (c )所示, 将 分割线 AA'进行顺时针旋转, 则 AA'由垂直方向变为水平方向; 控制设备自动 将会场 S1调整至目标屏幕的上部区域显示, 形成如图 16中(d )所示的多画面 显示模式。
根据本实施例的多画面显示模式设置方法, 用户可通过用手触摸控制设 备的控制区域, 即可灵活地进行分割线的生成、 删除、 移动和旋转等操作, 实现了有效、 便捷的多画面显示模式设置。 实施例三
在实施例一的基础上, 本实施例的多画面显示模式设置方法中, 用户可 通过用鼠标操作实现多画面显示模式设置。 具体地, 用户可通过鼠标的方式 对控制区域进行操作, 实现多画面分割线 (以下简称为 "分割线" )进行生 成、 删除、 移动和旋转等操作。 本实施例中的选择分割线的方式与实施例二 中介绍的选择方式相同。 下面分别针对上述各种多画面分割线的操作进行详 细说明。
(一)用户以鼠标方式生成分割线。
仍以图 6为例,用户欲在屏幕上画一条从 A点到 B点的线,可以先将鼠标移 动屏幕的 A点并点击, 然后在将鼠标移动到控制设备屏幕的 B点点击, 在结束 操作后, 即得到 A到 B的一个直线, 如图 6中的 (a ) 所示, 该操作作为多画面 分割线生成信息保存下来; 用户也可以在 A点点击后, 一直在屏幕上拖动, 控 制设备记录下鼠标在触摸屏幕的轨迹, 生成一条从 A点到 B点的曲线, 如图 6 中(b )所示的实线; 在用户结束操作后, 控制设备根据该曲线的 A点和 B的坐 标, 生成一条从 A点到 B点的直线, 如图 6中 (b )所示的虚线, 该分割线的属 性信息, 包括了该分割线的端点坐标(起始坐标和结束坐标) , 被作为多画 面分割线生成信息保存下来。 若控制设备允许用户在绘制的过程中任意以自 由态任意拖动, 则需要计算最终生成的 A点和 B点直线的倾斜率; 控制设备还 可以在用户生成分割线时给予约束, 即只允许在绘制时沿水平或者垂直方向 进行延伸。
(二)用户以鼠标方式移动分割线。
仍以图 7为例, 首先用鼠标选定分割线 AB, 选定的方式可以用短按鼠标 左键的方式, 将该分割线选定, 拖动分割线 AB从位置 1 1 '拖动到 22' , 操作完 毕后, 以 22'的端点坐标作为该直线的新的属性信息, 该操作对应移动一个分 割线的多画面分割线移动信息。
(三)用户以鼠标方式删除分割线。
用户首先选择屏幕上用以分割多画面的分割线, 然后按照上述移动分割 线的方式, 将该分割线拖出控制区域, 即表示将该分割线不再影响多画面的 配置, 由配置多画面的其它分割线来生成对应的多画面, 该操作对应删除一 个分割线的多画面分割线删除信息。
(四)用户以鼠标方式旋转分割线。
图 17为旋转多画面分割线的第二示意图。 旋转多画面分割线时, 鼠标方 式与触摸方式的操作不同, 例如想把分割线从垂直位置变换为水平位置。 如 图 17所示, 首先选定要旋转的分割线 AB (如图 17中 (a ) 所示) , 选定后将 鼠标移至 AB靠近中心位置时 (例如距离 AB中心点为距离小于 A点到 B点的距离 1/3)出现可旋转的符号提示 (如图 17中 (b ) 所示) ; 当出现可旋转的符号提 示时, 长按鼠标左键并向右侧拖动, 即可完成从垂直位置到水平位置的转换 (如图 17中 (c ) 所示) 。 操作完毕后, 以 22'的端点坐标作为该直线的新的 属性信息, 该操作对应旋转一个分割线的多画面分割线旋转信息。
控制设备通过上述用户操作得到了对应的多画面分割线操作信息后, 根 据多画面分割线操作信息生成对应的多画面显示模式的具体流程与实施例二 相同, 故此处不再赘述。 实施例四
除上述实施例二或三中所述的获取用户直接对分割线进行的操作之外, 控制设备还可获取用户对会议画面的拖动操作, 并根据该拖动操作生成相应 的多画面分割线操作信息, 并根据多画面分割线操作信息生成多画面显示模 式。
图 18为根据多画面分割线生成信息设置多画面显示模式的第三示意图。 如图 18所示, 例如当前具有 6个可显示的会场画面, 即会场 S1 -会场 S6。 控制 设备的辅助区域可用于显示四个当前屏幕未显示的会场画面。 例如在初始状 态下, 屏幕单屏显示会场 S1的画面, 辅助区域显示会场 S2-会场 S5的小画面, 此时多画面显示模式如图 18中的 (a ) 所示; 用户将辅助区域显示的会场 S2 的画面拖入到目标屏幕的右侧, 用户的该画面拖动操作隐含生成分割线 ΑΑ', 控制设备根据用户的该画面拖动操作生成多画面分割线生成信息, 并根据该 多画面分割线生成信息生成分割线 ΑΑ' , 此时多画面显示模式如图 18中的( b ) 所示; 在完成上述操作后, 辅助区域中显示会场 S3-会场 S6的小画面, 用户将 辅助区域显示的会场 S3的画面拖入到目标屏幕的左下方, 用户的该画面拖动 操作隐含生成分割线 BO, 控制设备根据用户的该画面拖动操作生成多画面分 割线生成信息, 并才艮据该多画面分割线生成信息生成分割线 BO, 此时多画面 显示模式如图 18中的(c )所示; 在完成上述操作后,辅助区域中显示会场 S4- 会场 S6的小画面, 用户将辅助区域显示的会场 S4的画面拖入到目标屏幕的右 下方, 用户的该画面拖动操作隐含生成分割线 ΟΒ', 控制设备根据用户的该画 面拖动操作生成多画面分割线生成信息, 并根据该多画面分割线生成信息生 成分割线 ΟΒ' , 此时多画面显示模式如图 18中的 (d )所示。 至此, 完成了将 单屏显示模式配置为 2 x 2的多画面, 并且屏幕中的各显示区域, 即各子画面 均显示用户指定的会场画面。
除了通过以拖拽分割线的方法来删除分割线之外, 也可以通过将会场画 面拖出显示区域的方法来删除分割线, 从而得到新的多画面显示模式。 图 19 为根据多画面分割线删除信息设置多画面显示模式的第二示意图。 如图 19所 示, 以将显示有一个会场 S1的四画面屏幕配置为一个 1 X 2的多画面显示模式 为例进行说明。 如图 19中的 (a ) 所示,目标屏幕是一个 4 x 4的多画面显示模 式; 用户将(a ) 中的会场 S4从显示区域拖出, 隐含删除分割线 ΟΒ, , 形成 如图 19中的 (b ) 所示多画面显示模式; 用户将(b ) 中的会场 S3从显示区域 拖出, 隐含删除分割线 BO, 形成如图 19中的 (c ) 所示多画面显示模式; 用 户将(c ) 中的会场 S2从显示区域拖出, 隐含删除分割线 ΑΑ', 形成如图 19中 的 (d ) 所示多画面显示模式。
此外, 还可通过对会场画面进行操作来移动或旋转分割线, 从而得到新 的多画面显示模式。
具体地, 接收所述用户对所述待操作的会场画面进行尺寸调节操作的滑 动轨迹, 根据尺寸调节的滑动轨迹, 对用于构成显示所述待操作的会场画面 的显示区域的边界的多画面分割线进行移动; 例如通过拖拉会场画面的边界 来对会场画面的尺寸进行调节时, 等同于图 15中所示的同时移动两条相互交 叉的分割线进行多画面显示控制。
具体地, 接收所述用户在所述目标屏幕内对所述待操作的会场画面进行 拖动操作的滑动轨迹, 根据所述拖动操作的滑动轨迹, 对用于构成显示所述 待操作的会场画面的显示区域的边界的多画面分割线进行旋转。 以图 16为例, 当将会场画面 S1由图 16 ( a )所示的左侧位置拖动至图 16 ( d ) 中所示的上部 位置时, 可自动生成将分割线 AA'由图 16 ( a )中所示位置旋转至图 16 ( d )中 所示位置的多画面分割线旋转信息。 实施例五
在上述实施例的基础上, 控制设备还可结合多种多画面分割线操作信息 进行多画面显示模式设置, 以得到用户期望的多画面显示模式。
图 20为根据多种多画面分割线操作信息设置多画面显示模式的示意图。 如图 20所示, 将一个单屏显示模式设置为 3 X 3的多画面显示模式需通过四次 调整来实现。 初始状态下, 屏幕的显示模式如图 20中的(a )所示; 生成分割 线 ΒΒ', 屏幕切换为 1 X 2的多画面显示模式, 并生成分割线 ΑΑ', 屏幕切换为 2 x 2的多画面显示模式, 如图 20中的 (b ) 所示; 拖动 BB, 和 AA, 的交点 0 至 00' , 生成分割线 DD', 并生成分割线 CC', 形成如图 20中的(c )所示的多 画面显示模式; 生成分割线 DE和分割线 FC, 最终形成如图 20中的 (d )所示 的多画面显示模式。 实施例六
在上述任一实施例的基础上, 所述根据操作后的多画面分割线所形成的 多画面显示模式, 控制目标屏幕进行画面显示具体包括:
从预先存储的多画面显示模式中, 调取与第一多画面显示模式相近的第 二多画面显示模式, 并控制所述目标屏幕根据所述第二多画面显示模式进行 画面显示; 其中, 所述第一多画面显示模式为操作后的多画面分割线所形成 的多画面显示模式;
其中: 所述第二多画面显示模式与所述第一多画面显示模式具有相同数 量的显示区域, 或者
所述第二多画面显示模式与所述第一多画面显示模式的面积差, 小于预 先存储的多画面显示模式中任意其它多画面显示模式与所述第一多画面显示 模式的面积差。
由于常用的视频图像显示格式有 4:3和 16:9等, 如果用户以任何比例设置 图像大小, 都将相关会场的图像调整进行调整为用户设置的大小和比例, 则 往往需要进行裁剪和缩放操作, 这会耗费设备相当多的运算量, 导致系统端 到端延时的产生。 因此可将系统支持的各种多画面显示模式作为一个数据 库保存下来, 并在获得用户操作, 临时或虚拟生成与用户操作对应的第一多 画面显示模式后, 从数据库中查找与第一多画面显示模式最相似的第二多画 面显示模式, 并将该第二多画面显示模式作为屏幕的多画面显示模式。 其中, 相似性的判断例如基于两种多画面显示模式的显示区域的个数或各显示区域 相差面积等。 下面以基于相差面积来选择第二多画面显示模式为例进行说明。
图 21为数据库中保存的多画面显示模式示意图。 如图 21所示, 控制设备 可支持(a ) 至 (f ) 六种多画面显示模式。 图 22为根据第一多画面显示模式 选择第二多画面显示模式的示意图, 在图 22所示, 以虚线表示根据用户操作 形成第一多画面显示模式, 以实现表示数据库中的可支持的多画面显示模式。 图 22的( a )为将第一多画面显示模式与数据库中的第一种多画面显示模式(如 图 21中 (a )所示)进行比较, 其中阴影区域为两者相差面积, 记为第一相差 面积; 图 22的(b )为将第一多画面显示模式与数据库中的第二种多画面显示 模式(如图 21中 (b )所示)进行比较, 其中阴影区域为两者相差面积, 记为 第二相差面积; 按照相同方式, 可获得第一多画面显示模式与数据库中其余 四种多画面显示模式的相差面积, 此处未示出。 通过将各相差面积进行比较, 例如获知第一相差面积小于第二相差面积 (及其它各相差面积) , 则可选定 第二种多画面显示模式作为屏幕的多画面显示模式。
在上述实施例一至六的多画面显示的控制方法中, 虽然以用户通过触摸 操作或鼠标操作向控制设备提供用户操作的滑动轨迹为例, 对本发明实施例 的多画面显示的控制方法进行说明。 但本领域的技术人员能够理解, 控制设 备还可通过任意其它方式来接收用户操作的滑动轨迹时, 均能够实现本发明 实施例的技术方案。
例如, 控制设备通过手势识别的方式来接收用户操作的滑动轨迹。 具体 地, 控制设备中预先存储有与用户手势相对应的用户操作, 通过摄像头获取 用户手势和手势移动位置时, 根据用户手势与用户操作的映射关系, 识别出 用户操作, 并根据用户手势的移动位置形成用户操作的滑动轨迹。 更为具体 地, 例如当摄像头识别出用户食指伸直, 其他四指合拢的手势时, 若根据预 先存储的用户手势与用户操作的映射关系, 获知该手势对应于多画面分割线 生成操作; 并根据摄像头识别出用户保持该手势从一个位置 (对应于第一坐 标)移动至另一个位置 (对应于第二坐标) , 则生成以第一坐标和第二坐标 为两个端点的多画面分割线。 类似地, 通过预先定义分别与多画面分割线删 除操作、 移动操作和旋转操作对应的不同用户手势, 则可实现本发明实施例 的技术方案。 实施例七
