Restart Mac and test again. Sometimes a simple restart corrects things. If not, continue.
• If Apple's http://support.apple.com/kb/HT2090
suggestions do not help you, (the "reset" suggested there
often restores normal function,) continue with the following.
• Use your Mac's Disk Utility to repair permissions and then
download and apply the latest Combo Update. For your OS X (10.8.2),
the latest Combo is http://support.apple.com/kb/DL1676
• Repair permissions again immediately following the system restart
that completes the Combo update.
Properly applying the Combo version of updates can sometimes correct software problems, but, if your trouble is caused by a hardware problem, there are no user serviceable parts of the camera. For hardware help, contact Apple or an Apple-Authorized Service Provider for service.
(Over time, Apple has changed the built-in camera's name on newer Macs from "iSight" to "FaceTime" and then to "FaceTime HD." Regardless of the name of your Mac's built-in camera, the same info and troubleshooting applies.)
