This is an English website. I don't speak French but I tried an online translator on your post. I think you are saying ...
"when you upgraded your emachine E725 the integrated video camera is now all black"

Unfortunately eMachines does not offer W7 support so you will have to try the Vista drivers available for the camera. You have two choices Camera_Chicony or Camera_Suyin. Pick the one that matches your equipment. Link: Drivers eMachine E725

If those drivers do not work I'm afraid I don't know what else you can do.
