水波纹直播源码

① 用一个手机照着另一个手机直播的时候为什么下边的手机有水波纹

摘要 是屏幕分辨率的问题 就像你用手机拍电视 的效果是一样的

② 如何使用 HTML5 Canvas 制作水波纹效果

看看flash是怎么做的吧。水波波纹效果有好多种做法，实现难度不一样，效果也不一样。
比如这个
http://bbs.9ria.com/forum.php?mod=viewthread&tid=404246&highlight=%E6%B0%B4%E6%B3%A2
可以在论坛搜一搜，有讲原理的，也有直接贴源码的。用遮罩做比较简单，用柏林噪声做比较难。

③ 用手机录电视节目怎样才能没有水波纹

用手机录制电视机屏幕，因电视机的刷新频率太慢的问题，都无法避免水波纹，就好比你将任何遥控板发射器对准手机摄像头按任何键都会看见发光。

④ 看直播一卡一卡的还有水波纹，看别人直播就没事，是这个主播那边卡吗

摘要 是的，是那个主播的线路问题，他的频道可能是人多

⑤ 易语言 水波纹特效模块源码

没看懂你想表达什么，你想要这个模块源码还是让它不公开？

⑥ 摩尔纹是什么

摩尔纹现象主要影响在于电视摄像，如果现有的led大屏幕存在像素间发光不平衡、成像效果不好、近距离观看炫目，会出现摩尔纹，从而影响led大屏幕在演播室的推广使用。

消除摩尔纹的几类方法，消除摩尔纹现象，可以从画面拍摄和画面显示两方面解决。摄像机像素偏置技术：摩尔纹现象是由于图像细节小于每一个图像传感器之间的间隔所造成的。而空间偏置尽可能地提高CCD摄像机亮度水平分辨率。但是，这种方法，仍不能彻底消除led大屏幕摩尔纹，原因是图像传感器仍存在一定的空间频率，无法连续成一个面。

光学处理幕消除摩尔纹：通过光学处理的led大屏幕，摄像机几乎可在任何角度、任何位置、任何焦距都可以拍摄出不产生摩尔纹的图像。光学处理好的led大屏幕，其亮度、色温满足电视拍摄要求，不会出现摩尔纹干扰现象。目前，国内外一些厂家已掌握了相关技术。

在led大屏幕发光管表面固定一层光学处理幕。目前，光学处理幕技术已经得到应用，上海三思公司为上海青浦电视台设计制造的P2小间距led大屏幕就是一个应用案例。光学处理幕须紧贴显示屏发光管;光学处理幕选用特定比例的吸光材料和微珠透镜涂层，使其在透光性、色调等方面满足电视摄像要求。这块小间距led大屏幕亮度均匀度高，色彩还原饱和性高，能改善色温、白平衡；能够过滤90%以上的杂散光。图像清晰、柔和、色彩逼真，在特写镜头时，图像不失真。超大视角，给现场观众带来非常好的视觉体验。

⑦ 监控摄像头画面有水波纹是怎么回事

由于传输线的特性阻抗不匹配引起的故障现象，这种现象的表现形式是在监视器的画面上产生若干条间距相等的竖条干扰，干扰信号的频率基本上是行频的整数倍。这是由于视频传输线的特性阻抗不是75Ω而导致阻抗失配造成的。

另外，值得注意的是，在视频传输距离很短时（一般为 150米以内），使用上述阻抗失配和分布参数过大的视频电缆不一定会出现上述的干扰现象。解决上述问题的根本办法是在选购视频电缆时，一定要保证质量。必要时应对电缆进行抽样检测。

(7)水波纹直播源码扩展阅读

红外半球系列机器晚上出现图像照度差、发白或有亮白色光圈现象。该现象是机器装配不当导致的，装配时感光器件（光敏电阻）离半球距离过远会导致红外灯启动不完全造成机器夜间照度差；

出现图像发白或亮白色光圈现象主要因红外发光管发出的红外光通过球罩折射到镜头所致，解决此现象就是避免让红外光折射到镜头表面，通常采用海绵圈进行镜头与红外光的隔离，在装配时一定要将球罩紧贴海绵圈。

⑧ 手机拍摄电脑和电视时，为何会产生水波纹现象

细心的朋友会发现，当我们用手机对着电脑屏幕或电视机屏幕拍照时，拍出来的照片上往往都会有一些不规则的波纹，如同水面收到刺激散开的水纹一样。之所以出现这种现象主要与这些电子产品的刷新率有关，通常我们的肉眼是无法捕捉到这一微小的变化的，但是用手机拍照则不同，手机能迅速的捕捉到屏幕的刷新率，若是频率与自己不相同便会使得照片出现波纹现象，此外条纹之间的相互干扰也是原因之一。

若要解决这个问题，就要尽量使得手机拍照时的刷新率与屏幕的刷新率一致，所以要购买刷新率较高的屏幕。此外，通过调整手机拍摄时的角度或距离也能够使得手机拍摄的频率接近屏幕的刷新率，从而在一定程度上避免出现这种现象。如若是想得到清晰的图片建议不要使用拍照的方式，改用截图。
