网路摄影机（webcam）编辑本段回目录
网路摄影机（webcam）一般具有视讯摄影/传播和静态图像捕捉等基本功能，它是借由镜头采集图像后，由网路摄影机内的感光元件电路及控制元件对图像进行处理并转换成电脑所能识别的数位讯号，然后借由Parallel或USB连接输入到电脑后由软体再进行图像还原。
历史
1991年, 世界第一支网路摄影机（称为 CoffeeCam），首度出现在英国剑桥大学的泰贾屋咖啡店 （Trojan room coffee pot）。最古老的网路摄影机, 是旧金山州立大学（San Francisco State University）的 FogCam, 自1994年使用至今。
视讯会议
目前许多程式都可以支援视讯会议，这些程式包含： Yahoo Messenger, AOL Instant Messenger (AIM), Windows Live Messenger, Skype, iChat, Paltalk（目前改名为PaltalkScene）, Ekiga, Stickam, Tokbox, Camfrog 以及 meetcam。
技术
USB video device class (UVC) 可支援各式的网路摄影机，因此电脑不必再安装多余的驱动程式。目前Microsoft Windows Vista, Linux 和 Mac OS X 10.4 与 10.5 皆有支援内建的 UVC drivers.
感光元件
网路摄影机的感光元件类型有：
CMOS
CCD
目前有不少新式的网路摄影机已可支援 multi-megapixel 的解析度, 某些摄影镜头更拥有高帧率, 像是 PlayStation Eye, 可以产生 320×240 ，每秒 120 帧（frames）.
连接阜类型
