[60] 图 8为本发明实施例一种终端设备的结构示意图。 具体实施方式
[61] 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、 完整地描述， 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作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。 [62] 如图 1所示， 为本发明实施例一通信系统中终端间进行图像共享的应用场景示 意图，该通信系统包含发送端和接收端。其中，发送端与接收端通过局域网建立连接， 例如通过 WI-FI (无线-保真）建立连接， 连接后， 在发送端和接收端分别启动屏幕共 享的应用程序， 从而进入屏幕共享模式，此模式下在发送端对屏幕的操作都会视为选 择共享区域的操作， 之后发送端和接收端之间即可进行图像等信息共享。其中， 该发 送端和接收端可以分别是手机、 电视、 手写本、 PAD 等终端中的任意一个， 发送端 与接收端可以是相同类型的终端， 也可以是不同类型的终端， 例如发送端是手机， 接 收端是电视； 上述图像可以是单张图片或一段视频中的连续多个图像等。上述两终端 建立连接的过程无需在每次进行图像等信息共享时重复执行。
[63] 该发送端与接收端间的图像共享方法， 如图 2a所示， 可以包括：
[64] 步骤 101， 发送端确定其屏幕所显示图像上的共享区域。
[65] 需要说明的是， 在所述发送端确定其屏幕所显示图像上的共享区域之前， 所述 发送端与所述接收端需要首先通过局域网建立连接。
[66] 发送端在与接收端进行屏幕上的局部图像共享时， 发送端首先确定其屏幕所显 示的图像中需要进行图像共享的共享区域， 如图 2b所示的图像中的共享区域 11。 该 共享区域内的图像即为需要共享的图像。
[67] 该共享区域的确定具体可以是用户在发送端屏幕上选择的共享区域， 其中， 该 共享区域可以是用户预先在发送端上设定的，例如预先设定共享区域为屏幕中心一固 定尺寸的区域； 该共享区域也可以是用户在进行局部图像共享时临时划定的区域。该 共享区域可以为任意形状， 不一定为矩形。
[68] 发送端在确定共享区域时， 可以读取用户预先设定的共享区域的坐标， 或者获 取用户在屏幕上划定的共享区域进而获得共享区域的坐标。在获取用户在屏幕上划定 的共享区域时，可以首先获得用户在屏幕上滑动产生的轨迹， 识别该轨迹是否为闭环 轨迹或接近闭环的轨迹， 如果是， 则将闭环轨迹或接近闭环的轨迹所包围的区域作为 共享区域。
[69] 步骤 102， 发送端对非共享区域的图像进行处理， 以屏蔽该非共享区域的图像。
[70] 发送端在确定共享区域后， 该图像上除共享区域外的区域即为非共享区域， 接 下来， 发送端需要对该非共享区域的图像进行处理， 以屏幕该非共享区域的图像。应 当理解的是，相对于屏幕所显示的原始图像， 处理后的所述屏幕所显示的图像对所述 非共享区域的图像进行了屏蔽。
[71] 具体的， 可以对该非共享区域的图像进行单色着色处理。 比如， 将该非共享区 域的图像中各像素点全部着白色或者着黑色。例如图 2b所示， 除了共享区域 11之外 的非共享区域的图像全部着白色， 即可屏蔽图像中非共享区域的 "A、 B、 C、 K、 L、 Μ"。
[72] 该图像处理过程仅在内存中操作， 不会在发送端的屏幕上进行显示。 当然也还 可以对该非共享区域的图像进行其他处理， 只要可以屏蔽该非共享区域的图像即可。
[73] 步骤 103，发送端将处理后的该屏幕所显示的图像的数据通过局域网向接收端发 送， 以使发送端与接收端共享该共享区域的图像。
[74] 发送端通过局域网将处理后的图像发送至接收端， 该图像是发送端屏幕显示的 处理后的完整图像， 既包含共享区域的图像， 也包含处理后的非共享区域的图像。
[75] 由接收端根据接收到的图像进行输出显示。 如图 2b所示， 由于非共享区域的图 像进行了着白色处理， 与整个图像的背景色一致， 因此， 在接收端所显示的图像对于 用户来说只能看到共享区域的图像， 即 "D E F H I J"。 [76] 在发送该处理后的图像时， 发送端可以对处理后的图像数据进行编码压缩， 还 可以进行分辨率的处理后再发送。
[77] 本发明实施例通过对图像划定共享区域及非共享区域， 并对非共享区域的图像 进行处理， 以屏蔽非共享区域图像， 实现了局域网中两终端之间局部图像的共享， 满 足了用户的安全性、个性化的需求， 而且在局域网环境下终端之间可以实时快速地分 享屏幕， 终端之间图像的传输无需通过运营商网络， 也无需中央服务器的支持， 从而 避免了通过运营商网络传输存在的流量大及传输时延， 不能实时动态共享的问题。
[78] 在本发明的另一实施例中， 发送端与接收端间的图像共享方法还可以如图 2c所 示， 该实施例与前述实施例的区别在于， 增加了步骤 111， 发送端接收接收端发送的 屏幕共享请求， 发送端在接收到该请求后再执行步骤 112: 响应来自所述接收端的屏 幕共享请求， 所述发送端确定其屏幕所显示图像上的共享区域。
[79] 其中， 步骤 112与前述步骤 101类似， 步骤 113与前述步骤 102类似， 步骤 114 与前述步骤 103类似， 此处不再赘述。
[80] 在本发明的另一实施例中， 发送端与接收端之间可以共享一幅或多幅图像， 如 果发送端需要进行局部图像共享的是多幅图片 （例如一段视频中的多幅图像）， 则可 以针对每一幅图像执行上述步骤实现每幅图像的局部图像共享，每一图像的共享区域 可以相同， 也可以不同。
[81] 若多幅图片的共享区域相同， 则发送端在执行上述步骤 102 103时可以对这多 幅图片进行批量处理， 例如在执行步骤 102时， 发送端在确定共享区域后， 可以依次 对每幅图像中非共享区域的图像进行处理，执行步骤 103时， 发送端一次将所有处理 后的图像发送至接收端。 上述步骤还可以有其它变化， 此处不做限定。
[82] 参见图 3a， 为本发明实施例另一种终端间的图像共享方法流程图。
[83] 首先， 发送端与接收端通过局域网建立连接。 该方法可以包括：
[84] 步骤 201，接收端接收发送端通过局域网发送的图像数据及非共享区域的位置信 息， 其中， 非共享区域为发送端屏幕所显示的图像中除共享区域之外的区域。
[85] 发送端首先确定出共享区域， 该确定共享区域的方法与前述步骤 101类似。 在 确定出共享区域后，发送端直接将当前屏幕上显示的完整图像以及非共享区域的位置 信息发送到接收端。其中， 该非共享区域的位置信息可以是该非共享区域在图像中的 坐标位置。 [86] 接收端接收到上述信息后， 执行步骤 202。
[87] 步骤 202，接收端根据非共享区域的位置信息对图像中非共享区域的图像进行处 理， 以屏蔽非共享区域的图像。
[88] 接收端首先根据非共享区域的位置信息在接收到的图像中确定出共享区域和非 共享区域。然后， 接收端对非共享区域的图像进行图像处理， 以屏蔽非共享区域的图 像。
[89] 具体的， 可以对该非共享区域的图像进行单色着色处理。 比如， 将该非共享区 域的图像中各像素点全部着白色或者着黑色。该过程与前述步骤 102中的图像处理过 程类似， 此处不再赘述。
[90] 接收端在上步骤接收到的图像不会在屏幕上显示， 上述图像处理过程也仅在内 存中操作。当然也还可以对该非共享区域的图像进行其他处理， 只要可以屏蔽该非共 享区域的图像即可。
[91] 步骤 203，接收端输出并显示处理后的图像， 以使发送端与接收端共享该共享区 域的图像。 [92] 接收端在处理好图像后， 将处理后的图像输出， 输出的图像中由于非共享区域 图像的屏蔽， 对于用户来说， 无法观察到原图像中非共享区域的图像， 但是能观察到 共享区域的图像。
[93] 本实施例中通过对图像划定共享区域及非共享区域， 并对非共享区域的图像进 行处理， 以屏蔽非共享区域图像， 实现了局域网中两终端之间局部图像的共享， 满足 了用户的安全性、个性化的需求， 而且在局域网环境下终端之间可以实时快速地分享 屏幕， 终端之间图像的传输无需通过运营商网络， 也无需中央服务器的支持， 从而避 免了通过运营商网络传输存在的流量大及传输时延， 不能实时动态共享的问题。
[94] 在本发明的另一实施例中，发送端与接收端间的图像共享方法还可以如图 3b所 示， 该实施例与前述实施例的区别在于， 增加了步骤 211， 接收端向发送端发送屏幕 共享请求， 发送端在接收到该请求后发送共享的相关信息，然后再由接收端执行步骤
212。
[95] 其中， 步骤 212与前述步骤 201类似， 步骤 213与前述步骤 202类似， 步骤 214 与前述步骤 203类似， 此处不再赘述。 [96] 在本发明的另一实施例中， 发送端与接收端之间可以共享一幅或多幅图像， 如 果发送端需要进行局部图像共享的是多幅图片 （例如一段视频中的多幅图像）， 则接 收端可以针对每一幅图像执行上述步骤实现每幅图像的局部图像共享，每一图像的共 享区域可以相同， 也可以不同。
[97] 若多幅图片的共享区域相同， 则接收端在执行上述步骤 202时可以对这多幅图 片进行批量处理。 上述步骤还可以有其它变化， 此处不做限定。
[98] 以上是对本发明方法实施例的描述， 下面对实现上述方法的装置进行介绍。
[99] 参见图 4a， 为本发明实施例一种终端设备的结构示意图。
[100]该终端设备作为发送端与接收端通过局域网连接， 该终端设备可以包括：
[101]区域确定单元 301， 用于确定该终端设备的屏幕所显示图像上的共享区域； [102]图像处理单元 302，用于对非共享区域的图像进行处理， 以屏蔽所述非共享区域 的图像，其中，所述非共享区域为所述终端设备屏幕所显示的图像中除所述共享区域 之外的区域；
[103]信息发送单元 303，用于将处理后的所述屏幕所显示的图像的数据通过所述局域 网向所述接收端发送， 以使所述终端设备与所述接收端共享所述共享区域的图像。
[104]区域确定单元 301确定该终端设备屏幕上所显示图像中的共享区域， 其中， 该 共享区域可以是用户预先在该终端设备上设定的，例如预先设定共享区域为屏幕中心 的区域； 该共享区域也可以是用户在进行局部屏幕共享时临时划定的区域。 图像处理 单元 302对非共享区域的图像进行处理， 以屏蔽非共享区域的图像，然后将处理后的 图像发送至信息发送单元 303， 信息发送单元 303将处理后的图像发送至接收端。
[105]本发明实施例通过上述单元对图像划定共享区域及非共享区域， 并对非共享区 域的图像进行处理， 以屏蔽非共享区域图像， 实现了局域网中两终端之间局部图像的 共享， 满足了用户的安全性、个性化的需求， 而且在局域网环境下终端之间可以实时 快速地分享屏幕， 终端之间图像的传输无需通过运营商网络， 也无需中央服务器的支 持， 从而避免了通过运营商网络传输存在的流量大及传输时延， 不能实时动态共享的 问题。
[106]在本发明的另一实施例中， 如图 4b所示， 该终端设备还可以包括：
