(1) If you have not repaired permissions since installing iMovie, restart Mac and use Mac's Disk Utility to repair permissions. Then check to see if iMovie recognizes your inbuilt- iSight again.
If iSight is still not recognized, reinstall iMovie and repair permissions again after the reinstall is complete.
(To ensure that the installer and installed software can work properly, I always repair permissions before and after installing any software that asks for my user account and password.)

(2) Immediately following this (or any other Apple software installation), use
your Mac's > Software Update... to check for and install any needed
updates for your iMovie version.
If an update is required, install it and repair permissions again before testing iMovie again.
If you need to post back for other help, use your Mac's iMovie > About iMovie menu command to find the iMovie version you are using. Include your iMovie's version info in your next post. For example, mine shows iMovie '11 version 9.0.6 (1763). You should provide the equivalent info for your iMovie.
