本实施例提供了一种会议电视终端，请参考图1，包括：
终端本体101、摄像头模组102、激光模组103，视频信号由摄像头模组102采集后发送到终端本体101，激光显示信号由终端本体101发送到激光模组103，激光模组103根据激光显示信号将相应的显示信息投射在会场内。
摄像头模组102用于采集会场中的视频信息，即录像；录像可以固定视角录像，也可以改变视角录像，即摄像头模组102在终端本体101上可以是可旋转的，终端本体101以控制摄像头模组102的旋转，以及，还可以控制摄像头模组102的光圈、焦距等摄像参数，达到会议所需的效果。会议电视终端的设置位置，可以是在会场的端部，如会场的前方，侧方，后方等等，可以很好的采集到会场的信息。摄像头模组102将采集到的视频信号发送给终端本体101，由终端本体101处理该视频信号，然后再进行后续的转发、将视频信号进行播放等处理。视频信号的采集和处理过程可以是实时进行的，即摄像头模组102采集视频信号的同时，终端本体101相应的对视频信号进行处理，可以达到实时转发、播放的目的。
激光模组103用于根据终端本体101发送的激光显示信号，将相应的显示信息投 射在会场内。光是从组成物质的原子中发射出来的，原子获得能量后处于不稳定状态(也就是激发状态)，它会以光子的形式把能量发射出去。而激光，就是被引诱(激发)出来的光子队列，这光子队列中的光子们，光学特性一样，步调极其一致。普通光源是向四面八方发光，要让光朝着一个方向传播，需要给光源装上一定的聚光装置，如汽车的车前灯和探照灯都是安装有聚光作用的反光镜，使辐射光汇集起来像一个方向射出。然而，这只是表面上看起来汇聚，实际上仍然是杂乱无章。激光模组103中的激光发射器发射的激光，方向性极强，光束的发散性小，接近平行。那么，激光模组103发射的激光就可以很好的在投射物上形成激光的光斑，该光斑的尺寸小，多个激光发射器形成的激光模组103就可以通过合理的排布、激光的明灭、亮度的区别而在投射物上形成有意义的信息，该信息在本实施例中包括但不限于会场信息，其具体形式包括但不限于文字、图像。投射物，在会场中可以包括各个墙壁，或者投影幕布，投射物的表面颜色宜选择白色或者灰色等浅色，使激光模组103投射的信息比较清晰。本实施例中的激光模组103，其包括的激光发射器，不管是激光发射器的数量还是排布形式，均没有限定，可以排布成圆形，方形，椭圆形、甚至是不规则的形状，且各个激光发射器之间的间距也不一定相等，本实施例并不对激光模组103的具体形式做限定。
激光模组103和终端本体101之间的连接关系，可以包括：激光模组103设置在终端本体101上，即激光模组103和终端本体101作为一体的设备，也可以分离设置激光模组103和终端本体101，如图2所示，激光模组103通过有线或者无线的方式接收激光模组103发送的激光显示信号，并根据激光显示信号将相应的显示信息投射在会场内。
激光模组103发射激光的方向，至少部分与摄像头模组102一致，摄像头模组102采集激光模组103投射在会场内的显示信息。激光模组103，和/或摄像头模组102，是可以旋转的，在激光模组103发射激光的方向，至少部分与摄像头模组102一致时，激光模组103投射在会场内的显示信息可以被摄像头模组102采集到；摄像头模组102用于采集视频信号，视频信号中，包括激光模组103投射在会场内的显示信息，即摄像头模组102采集到会场的视频信息时，还可以采集到显示信息，这样在终端本体101对会场的视频信号的处理中，会场信息已经添加进去了，处理过程更加简单，不同于现有技术中的由摄像头模组102采集视频信号，然后将会场信息以字幕等形式 叠加在处理视频信号得到的视频信息中，减少了处理步骤，也不会有因为内容过多出现字幕过多占用画面的问题。
此外，可选的，激光模组103还包括调整单元，至少用于调节激光模组103的激光发射方向。激光模组103的激光发射方向，在本实施例中至少包括与摄像头模组102方向一致，以便摄像头模组102将激光模组103投射的显示信息进行采集；激光模组103投射显示信息还可以朝向其他的方向，如使与会人员能够轻易看到显示信息的方向，即激光模组103的激光发射方向朝向会场的前方。由于会场的各个方向上的投射物，如会场的墙壁，或者投影幕布，与激光模组103的位置之间可能会出现区别，那么，调整单元调节激光模组103的激光发射方向还可以适应各个投射物的距离进行调整，使激光模组103投射的显示信息更加清晰，更容易被与会人员或者摄像头模组102采集到。这里的调整可以是激光模组103的激光发射方向的大调整，也可以是在一个方向上的微调，甚至是调整激光模组103中的各个激光发射器的不同发射方向，在本实施例中都是可行的。
激光模组103投射在会场内的显示信息，由激光显示信号所决定。激光显示信号，由终端本体101发送给激光模组103，但激光显示信号的具体来源不限于终端本体101。可选的，还包括处理单元，激光显示信号包括输入信号和显示信号，处理单元用于将输入信号处理为显示信号，激光模组103则根据显示信号将相应的显示信息投射在会场内。输入信号可以是用户输入的信号，也可以是终端本体101等设备自动输入的信号，即终端本体101等设备可以根据会场信息自动生成输入信号；输入信号是电信号，其需要通过控制单元转化为可控制激光模组103将相应的显示信息投射在会场内的显示信号，激光模组103可根据该显示信号，调节激光的发射参数，比如角度、亮度、间距等等，以达到将相应的显示信息投射在会场中的目的。
激光模组103投射的显示信息可以是用于标识会场主题的信息，比如“XXX会议”，也可以是其他会议信息，公示等等；在一次会议中，激光模组103投射的信息是可以变化的，也可以通过多个激光模组103来投射多个不同的显示信息的目的，除了起到很好的标识作用，也可以使会场的显示效果更佳。

激光模组103投射在会场内的显示信息，由激光显示信号所决定。激光显示信号，由终端本体101发送给激光模组103，但激光显示信号的具体来源不限于终端本体101。可选的，还包括处理单元，激光显示信号包括输入信号和显示信号，处理单元用于将输入信号处理为显示信号，激光模组103则根据显示信号将相应的显示信息投射在会场内。输入信号可以是用户输入的信号，也可以是终端本体101等设备自动输入的信号，即终端本体101等设备可以根据会场信息自动生成输入信号；输入信号是电信号，其需要通过控制单元转化为可控制激光模组103将相应的显示信息投射在会场内的显示信号，激光模组103可根据该显示信号，调节激光的发射参数，比如角度、亮度、间距等等，以达到将相应的显示信息投射在会场中的目的。

本实施例提供了一种会议电视终端，包括终端本体、摄像头模组、激光模组，视频信号由摄像头模组采集后发送到终端本体，激光显示信号由终端本体发送到激光模 组，激光模组根据激光显示信号将相应的显示信息投射在会场内，用激光模组投射取代了横幅，重复利用率高，且激光模组与终端本体进行交互，提供了系统的整体性，便于安装和管理。
第三实施例
本实施例提供了一种会议电视终端10的在会场中的应用场景，请参考图5，会议电视终端10包括：终端本体、摄像头模组、激光模组，视频信号由摄像头模组采集后发送到终端本体，激光显示信号由终端本体发送到激光模组，激光模组根据激光显示信号将相应的显示信息投射在会场内。
会场内部的形状一般是矩形或者圆形；矩形的会场，其靠近一边的位置是主席台，这边是长边还是短边则因会场的建筑方式而异。与会人员则在主席台下，一般是呈阶梯状或者是平行的就坐，在会议开始后，各个与会人员的位置基本上就固定了。此时，会议电视终端10则可以设置在主席台的位置，摄像头模组面向与会人员。
摄像头模组采集视频信号，就是进行录像，录像可以固定视角录像，也可以改变视角录像，摄像头模组往往会有一定范围的旋转空间，根据需要，在终端本体的控制下进行相应的视频信号的采集。在采集的过程中，摄像头模组可以在终端本体的控制下随时调整视角，还可以调整焦距、光圈等摄像参数，有目的性的进行视频信号的采集。
而激光模组，用于根据终端本体发送的激光显示信号，将相应的显示信息投射在会场内。激光模组发射的激光就可以很好的在投射物上形成激光的光斑，该光斑的尺寸小，多个激光发射器形成的激光模组就可以通过合理的排布、激光的明灭、亮度的区别而在投射物上形成有意义的信息，该信息在本实施例中包括但不限于会场信息，其具体形式包括但不限于文字、图像。而投射物，在本实施例中，包括会场的各个墙壁，激光模组发射激光，将激光投射在会场的墙壁上，将相应的显示信息进行显示。
在激光模组发射激光的方向，部分与摄像头模组一致时，如图6所示，摄像头模组采集激光模组投射在会场内的显示信息。摄像头模组采集视频信号，视频信号中，包括激光模组投射在会场内的显示信息，即摄像头模组采集到会场的视频信息时，还可以采集到显示信息，这样在终端本体对会场的视频信号的处理中，会场信息已经添加进去了，处理过程更加简单，不同于现有技术中的由摄像头模组采集视频信号，然 后将会场信息以字幕等形式叠加在处理视频信号得到的视频信息中，减少了处理步骤，也不会有因为内容过多出现字幕过多占用画面的问题。
此外，激光模组发射激光的方向还可以与摄像头模组不一致，如图7所示，其作用在于，激光模组发射激光，投影在会场的墙壁上，直接将显示信息显示给与会人员，使与会人员直接知道显示信息的内容。图中仅仅示出了激光模组发射激光的方向与摄像头模组方向相反，事实上，激光模组发射激光的方向可以与摄像头模组的方向成任何角度，以激光模组投射在会场墙壁上的显示信息清晰和完整为准。
会场的各面墙壁与激光模组的距离不尽相同，那么，激光模组的激光发射方向还可以适应各面墙壁的距离进行调整，使激光模组投射的显示信息更加清晰，更容易被与会人员或者摄像头模组采集到。具体的调整方式，可以是激光模组的激光发射方向的大调整，也可以是在一个方向上的微调，甚至是调整激光模组中的各个激光发射器的不同发射方向，在本实施例中都是可行的。
此外，激光模组除了可以通过旋转的方式实现向不同的方向投影之外，还可以通过设置多个激光模组，或者将激光模组设置在多个方向上，以达到向不同的方向投射显示信息的目的。激光模组设置在终端本体的各个方向上，这些不同方向上的激光模组可以通过不同的控制线路，接收终端本体发送的激光显示信号，从而将相应的显示信息投影在会场的墙壁上；也可以通过一致的控制线路，接收终端本体发送的激光显示信号。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
