Perhaps.
• If you have not already done so, restart Mac and
try again. If the iSight still does not work, continue.
• If Apple's http://support.apple.com/kb/HT2090
suggestions do not help you, (be certain that you
use the correct PMU/SMC "reset" procedure for your
Mac model), yours may be a hardware problem
that will require a professional fix.
• Test more than one Apple app in more than one
user account. If the problem persists with all,
Unless you have a current backup, make one now.
Then use the final "Troubleshooting" suggestion:
"... contact Apple or an Apple-Authorized Service Provider for service."
• If you want to try one more thing on your own first,
use Disk Utility to repair permissions. Then
download and apply the latest Combo Update for
your OS. Currently, the latest SL Combo is here:
http://support.apple.com/kb/DL1399
• 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 iSight so see your AASP if the Troubleshooting suggestions don't work.
